				The SIP-Server-Capabilities AVP (AVP Code 372) is of type Grouped.
				The Diameter indicates in this AVP the requirements for a particular
				SIP capability, so that the Diameter client (SIP server) is able to
				select another appropriate SIP server to serve the user.

				The SIP-Server-Capabilities AVP allows a Diameter client (SIP server)
				to select another SIP server for triggering or executing services to
				the user.  A user may have enabled some services that require the
				implementation of certain capabilities in the SIP server that
				triggers or executes those services.  For example, the SIP server
				that triggers or executes services to this user may need to implement
				SIP servlets [JSR-000116], Call Processing Language (CPL) [RFC3880],
				or any other kind of capability.  Or perhaps that user belongs to a
				premium users group that has a certain stringent quality-of-service
				agreement that requires a fast SIP server.  The capabilities required
				or recommended to a given user are conveyed in the
				SIP-Server-Capabilities AVP.  When it receives them, the Diameter
				client (SIP server) that does the SIP server selection needs to have
				the means to find out available SIP servers that meet the required or
				optional capabilities.  Such means are outside the scope of this
				specification.

				Note that the SIP-Server-Capabilities AVP assists the Diameter client
				(SIP server) to produce a subset of all the available SIP servers to
				be allocated to the user in the Home Realm; this is the subset that
				conforms the requirements of capabilities on a per-user basis.
				Typically this subset will be formed of more than a single SIP
				server, so once the subset of those SIP servers is identified, it is
				possible that several instances of these SIP servers exist, in which
				case the Diameter client (SIP server) should choose one particular
				SIP server to execute and trigger services to this user.  It is
				expected that at this point the SIP server (Diameter client) will
				follow the procedures of RFC 3263 [RFC3263] to allocate one SIP
				server to the user.

				The SIP-Server-Capabilities AVP is defined as follows (per the
				grouped-avp-def of RFC 3588 [RFC3588]):

				SIP-Server-Capabilities ::= < AVP Header: 372 >

				The SIP-Authentication-Scheme AVP (AVP Code 377) is of type
				Enumerated and indicates the authentication scheme used in the

				"auth-scheme" (see Section 1.2 of RFC 2617 [RFC2617]).  The only
				currently defined value is:

				o  DIGEST (0) to indicate HTTP Digest authentication as specified in
				RFC 2617 [RFC2617] Section 3.2.1.  Derivative work is also
				considered Digest authentication scheme, as long as the
				"auth-scheme" is identified as Digest in the SIP headers carrying
				the HTTP authentication.  This includes, e.g., the HTTP Digest
				authentication using AKA [RFC3310].

				Each HTTP Digest directive (parameter) is transported in a
				corresponding AVP, whose name follows the pattern Digest-*.  The
				Digest-* AVPs are RADIUS attributes imported from the RADIUS
				Extension for Digest Authentication [RFC4590] namespace, allowing a
				smooth transition between RADIUS and Diameter applications supporting
				SIP.  The Diameter SIP application goes a step further by grouping
				the Digest-* AVPs into the SIP-Authenticate, SIP-Authorization, and
				SIP-Authentication-Info grouped AVPs that correspond to the SIP WWW-
				Authenticate/Proxy-Authentication, Authorization/Proxy-Authorization,
				and Authentication-Info headers fields, respectively.

				Note: Due to the fact that HTTP Digest authentication [RFC2617] is
				the only mandatory authentication mechanism in SIP, this memo only
				provides support for HTTP Digest authentication and derivative
				work such as HTTP Digest authentication using AKA [RFC3310].
				Extensions to this memo can register new values and new AVPs to
				provide support for other authentication schemes or extensions to
				HTTP Digest authentication.

				Note: Although RFC 2617 [RFC2617] defines the Basic and Digest
				schemes for authenticating HTTP requests, RFC 3261 [RFC3261] only
				imports HTTP Digest as a mechanism to provide authentication in
				SIP.

				Due to syntactic requirements, HTTP Digest authentication has to
				escape quote characters in contents of HTTP Digest directives.  When
				translating directives into Digest-* AVPs, the Diameter client or
				server removes the surrounding quotes where present, as required by
				the syntax of the Digest-* attributes defined in the "RADIUS
				Extension for Digest Authentication" [RFC4590].

			The User-Authorization-Request (UAR) is indicated by the Command-Code
			set to 283 and the Command Flags' 'R' bit set.  The Diameter client
			in a SIP server sends this command to the Diameter server to request
			authorization for the SIP User Agent to route a SIP REGISTER request.
			Because the SIP REGISTER request implicitly carries a permission to
			bind an AOR to a contact address, the Diameter client uses the
			Diameter UAR as a first authorization request towards the Diameter
			server to authorize the registration.  For instance, the Diameter
			server can verify that the AOR is a legitimate user of the realm.

			The Diameter client in the SIP server requests authorization for one
			of the possible values defined in the SIP-User-Authorization-Type AVP
			(Section 9.10).

			The user name used for authentication of the user is conveyed in a
			User-Name AVP (defined in the Diameter base protocol, RFC 3588
			[RFC3588]).  The location of the authentication user name in the SIP
			REGISTER request varies depending on the authentication mechanism.
			When the authentication mechanism is HTTP Digest as defined in RFC
			2617 [RFC2617], the authentication user name is found in the
			"username" directive of the SIP Authorization header field value.
			This Diameter SIP application only provides support for HTTP Digest
			authentication in SIP; other authentication mechanisms are not
			currently supported.

			The SIP or SIPS URI to be registered is conveyed in the SIP-AOR AVP
			(Section 9.8).  Typically this SIP or SIPS URI is found in the To
			header field value of the SIP REGISTER request that triggered the
			Diameter UAR message.

			The SIP-Visited-Network-Id AVP indicates the network that is
			providing SIP services (e.g., SIP proxy functionality or any other
			kind of services) to the SIP User Agent.

			The Message Format of the UAR command is as follows:

			<UAR> ::= < Diameter Header: 283, REQ, PXY >

			/*
			The User-Authorization-Answer (UAA) is indicated by the Command-Code
			set to 283 and the Command Flags' 'R' bit cleared.  The Diameter
			server sends this command in response to a previously received
			Diameter User-Authorization-Request (UAR) command.  The Diameter
			server indicates the result of the requested registration
			authorization.  Additionally, the Diameter server may indicate a
			collection of SIP capabilities that assists the Diameter client to
			select a SIP proxy to the AOR under registration.


			In addition to the values already defined in RFC 3588 [RFC3588], the
			Result-Code AVP may contain one of the values defined in
			Section 10.1.

			Whenever the Diameter server fails to process the Diameter UAR
			message, it MUST stop processing and return the relevant error in the
			Diameter UAA message.  When there is success in the process, the
			Diameter server MUST set the code to DIAMETER_SUCCESS in the Diameter
			UAA message.

			If the Diameter server requires a User-Name AVP value to process the
			Diameter UAR request, but the Diameter UAR message did not contain a
			User-Name AVP value, the Diameter server MUST set the Result-Code AVP
			value to DIAMETER_USER_NAME_REQUIRED (see Section 10.1.2) and return
			it in a Diameter UAA message.  Upon reception of this Diameter UAA
			message with the Result-Code AVP value set to
			DIAMETER_USER_NAME_REQUIRED, the SIP server typically requests
			authentication by sending a SIP 401 (Unauthorized) or SIP 407 (Proxy
			Authentication Required) response back to the originator.

			When the authorization procedure succeeds, the Diameter server
			constructs a User-Authorization-Answer (UAA) message that MUST
			include (1) the address of the SIP server already assigned to the
			user name, (2) the capabilities needed by the SIP server (Diameter
			client) to select another SIP server for the user, or (3) a
			combination of the previous two options.

			If the Diameter server is already aware of a SIP server allocated to
			the user, the Diameter UAA message contains the address of that SIP
			server.

			The Diameter UAA message contains the capabilities required by a SIP
			server to trigger and execute services.  It is required that these
			capabilities are present in the Diameter UAA message due to the
			possibility that the Diameter client (in the SIP server) allocates a
			different SIP server to trigger and execute services for that
			particular user.

			If a User-Name AVP is present in the Diameter UAR message, then the
			Diameter server MUST verify the existence of the user in the realm,
			i.e., the User-Name AVP value is a valid user within that realm.  If
			the Diameter server does not recognize the user name received in the
			User-Name AVP, the Diameter server MUST build a Diameter User-
			Authorization-Answer (UAA) message and MUST set the Result-Code AVP
			to DIAMETER_ERROR_USER_UNKNOWN.


			If a User-Name AVP is present in the Diameter UAR message, then the
			Diameter server MUST authorize that User-Name AVP value is able to
			register the SIP or SIPS URI included in the SIP-AOR AVP.  If this
			authorization fails, the Diameter server must set the Result-Code AVP
			to DIAMETER_ERROR_IDENTITIES_DONT_MATCH and send it in a Diameter
			User-Authorization-Answer (UAA) message.

			Note: Correlation between User-Name and SIP-AOR AVP values is
			required in order to avoid registration of a SIP-AOR allocated to
			another user.

			If there is a SIP-Visited-Network-Id AVP in the Diameter UAR message,
			and the SIP-User-Authorization-Type AVP value received in the
			Diameter UAR message is set to REGISTRATION or REGISTRATION&
			CAPABILITIES, then the Diameter server SHOULD verify whether the user
			is allowed to roam into the network specified in the
			SIP-Visited-Network-Id AVP in the Diameter UAR message.  If the user
			is not allowed to roam into that network, the Diameter AAA server
			MUST set the Result-Code AVP value in the Diameter UAA message to
			DIAMETER_ERROR_ROAMING_NOT_ALLOWED.

			If the SIP-User-Authorization-Type AVP value received in the Diameter
			UAR message is set to REGISTRATION or REGISTRATION&CAPABILITIES, then
			the Diameter server SHOULD verify whether the SIP-AOR AVP value is
			authorized to register in the Home Realm.  Where the SIP AOR is not
			authorized to register in the Home Realm, the Diameter server MUST
			set the Result-Code AVP to DIAMETER_AUTHORIZATION_REJECTED and send
			it in a Diameter UAA message.

			When the SIP-User-Authorization-Type AVP is not present in the
			Diameter UAR message, or when it is present and its value is set to
			REGISTRATION, then:

			o  If the Diameter server is not aware of any previous registration
			of the user name (including registrations of other SIP AORs
			allocated to the same user name), then the Diameter server does
			not know of any SIP server allocated to the user.  In this case,
			the Diameter server MUST set the Result-Code AVP value to
			DIAMETER_FIRST_REGISTRATION in the Diameter UAA message, and the
			Diameter server SHOULD include the required SIP server
			capabilities in the SIP-Server-Capabilities AVP value in the
			Diameter UAA message.  The SIP-Server-Capabilities AVP assists the
			Diameter client (SIP server) to select an appropriate SIP server
			for the user, according to the required capabilities.

			o  In some cases, the Diameter server is aware of a previously
			assigned SIP server for the same or different SIP AORs allocated
			to the same user name.  In these cases, re-assignment of a new SIP
			server may or may not be needed, depending on the capabilities of
			the SIP server.  The Diameter server MUST always include the
			allocated SIP server URI in the SIP-Server-URI AVP of the UAA
			message.  If the Diameter server does not return the SIP
			capabilities, the Diameter server MUST set the Result-Code AVP in
			the Diameter UAA message to DIAMETER_SUBSEQUENT_REGISTRATION.
			Otherwise (i.e., if the Diameter server includes a
			SIP-Server-Capabilities AVP), then the Diameter server MUST set
			the Result-Code AVP in the Diameter UAA message to
			DIAMETER_SERVER_SELECTION.  Then the Diameter client determines,
			based on the received information, whether it needs to select a
			new SIP server.

			When the SIP-User-Authorization-Type AVP value received in the
			Diameter UAR message is set to REGISTRATION&CAPABILITIES, then
			Diameter Server MUST return the list of capabilities in the
			SIP-Server-Capabilities AVP value of the Diameter UAA message, it
			MUST set the Result-Code to DIAMETER_SUCCESS, and it MUST NOT return
			a SIP-Server-URI AVP.  The SIP-Server-Capabilities AVP enables the
			SIP server (Diameter client) to select another appropriate SIP server
			for invoking and executing services for the user, depending on the
			required capabilities.  The Diameter server MAY leave the list of
			capabilities empty to indicate that any SIP server can be selected.

			When the SIP-User-Authorization-Type AVP value received in the
			Diameter UAR message is set to DEREGISTRATION, then:

			o  If the Diameter server is aware of a SIP server assigned to the
			SIP AOR under deregistration, the Diameter server MUST set the
			Result-Code AVP to DIAMETER_SUCCESS and MUST set the
			SIP-Server-URI AVP value to the known SIP server, and return them
			in the Diameter UAA message.

			o  If the Diameter server is not aware of a SIP server assigned to
			the SIP AOR under deregistration, then the Diameter server MUST
			set the Result-Code AVP in the Diameter UAA message to
			DIAMETER_ERROR_IDENTITY_NOT_REGISTERED.

			The Message Format of the UAA command is as follows:

			<UAA> ::= < Diameter Header: 283, PXY >

			The Multimedia-Auth-Request (MAR) command is indicated by the

			server to request that the Diameter server authenticate and authorize
			a user attempt to use some SIP service (in this context, SIP service
			can be something as simple as a SIP subscription or using the proxy
			services for a SIP request).

			The MAR command may also register the SIP server's own URI to the
			Diameter server, so that future LIR/LIA messages can return this URI.
			If the SIP server is acting as a SIP registrar (see examples in
			Sections 6.2 and 6.3), its Diameter client MUST include a SIP-
			Server-URI AVP in the MAR command.  In any other cases (see example
			in Section 6.4), its Diameter client MUST NOT include a SIP-Server-
			URI AVP in the MAR command.

			The SIP-Method AVP MUST include the SIP method name of the SIP
			request that triggered this Diameter MAR message.  The Diameter
			server can use this AVP to authorize some SIP requests depending on
			the method.

			The Diameter MAR message MUST include a SIP-AOR AVP.  The SIP-AOR AVP
			indicates the target of the SIP request.  The value of the AVP is
			extracted from different places in SIP request, depending on the
			semantics of the SIP request.  For SIP REGISTER messages the SIP-AOR
			AVP value indicates the intended public user identity under
			registration, and it is the SIP or SIPS URI populated in the To
			header field value (addr-spec as per RFC 3261 [RFC3261]) of the SIP
			REGISTER request.  For other types of SIP requests, such as INVITE,
			SUBSCRIBE, MESSAGE, etc., the SIP-AOR AVP value indicates the
			intended destination of the request.  This is typically populated in
			the Request-URI of the SIP request.  Extracting the SIP-AOR AVP value
			from the proper SIP header field is the Diameter client's
			responsibility.  Extensions to SIP (new SIP methods or new semantics)
			may require the SIP-AOR to be extracted from other parts of the
			request.

			If the SIP request includes some sort of authentication information,
			the Diameter client MUST include the user name, extracted from the
			authentication information of the SIP request, in the User-Name AVP
			value.

			The Multimedia-Auth-Answer (MAA) is indicated by the Command-Code set
			to 286 and the Command Flags' 'R' bit cleared.  The Diameter server
			sends this command in response to a previously received Diameter
			Multimedia-Auth-Request (MAR) command.

			In addition to the values already defined in RFC 3588 [RFC3588], the
			Result-Code AVP may contain one of the values defined in
			Section 10.1.

			If the Diameter server requires a User-Name AVP value to process the
			Diameter MAR request, but the Diameter MAR message did not contain a
			User-Name AVP value, the Diameter server MUST set the Result-Code AVP
			value to DIAMETER_USER_NAME_REQUIRED (see Section 10.1.2) and return
			it in a Diameter MAA message.  The Diameter server MAY include a
			SIP-Number-Auth-Items AVP and one or more SIP-Auth-Data-Item AVPs
			with authentication information (e.g., a challenge).  Upon reception
			of this Diameter MAA message with the Result-Code AVP value set to
			DIAMETER_USER_NAME_REQUIRED, the SIP server typically requests
			authentication by generating a SIP 401 (Unauthorized) or SIP 407
			(Proxy Authentication Required) response back to the originator.

			If the User-Name AVP is present in the Diameter MAR message, the
			Diameter server MUST verify the existence of the user in the realm,
			i.e., the User-Name AVP value is a valid user within that realm.  If
			the Diameter server does not recognize the user name received in the
			User-Name AVP, the Diameter server MUST build a Diameter
			Multimedia-Auth-Answer (MAA) message and MUST set the Result-Code AVP
			to DIAMETER_ERROR_USER_UNKNOWN.

			If the SIP-Methods AVP value of the Diameter MAR message is set to
			REGISTER and a User-Name AVP is present, then the Diameter server
			MUST authorize that User-Name AVP value is able to use the URI
			included in the SIP-AOR AVP.  If this authorization fails, the
			Diameter server must set the Result-Code AVP to
			DIAMETER_ERROR_IDENTITIES_DONT_MATCH and send it in a Diameter
			Multimedia-Auth-Answer (MAA) message.

			Note: Correlation between User-Name and SIP-AOR AVP values is only
			required for SIP REGISTER request, to prevent a user from
			registering a SIP-AOR allocated to another user.  In other types
			of SIP requests (e.g., INVITE), the SIP-AOR indicates the intended
			destination of the request, rather than the originator of it.

			The Diameter server MUST verify whether the authentication scheme
			(SIP-Authentication-Scheme AVP value) indicated in the grouped
			SIP-Auth-Data-Item AVP is supported or not.  If that authentication
			scheme is not supported, then the Diameter server MUST set the
			Result-Code AVP to DIAMETER_ERROR_AUTH_SCHEME_NOT_SUPPORTED and send
			it in a Diameter Multimedia-Auth-Answer (MAA) message.

			If the SIP-Number-Auth-Items AVP is present in the Diameter MAR
			message, it indicates the number of authentication data items that
			the Diameter client is requesting.  It is RECOMMENDED that the
			Diameter server, when building the Diameter MAA message, includes a
			number of SIP-Auth-Data-Item AVPs that are a subset of the
			authentication data items requested by the Diameter client in the
			SIP-Number-Auth-Items AVP value of the Diameter MAR message.

			If the SIP-Server-URI AVP is present in the Diameter MAR message,
			then the Diameter server MUST compare the stored SIP server (assigned
			to the user) with the SIP-Server-URI AVP value (received in the
			Diameter MAR message).  If they don't match, the Diameter server MUST
			temporarily save the newly received SIP server assigned to the user,
			and MUST set an "authentication pending" flag for the user.  If they
			match, the Diameter server shall clear the "authentication pending"
			flag for the user.

			In any other situation, if there is a success in processing the
			Diameter MAR command and the Diameter server stored the
			SIP-Server-URI, the Diameter server MUST set the Result-Code AVP
			value to DIAMETER_SUCCESS and return it in a Diameter MAA message.

			If there is a success in processing the Diameter MAR command, but the
			Diameter server does not store the SIP-Server-URI because the AVP was
			not present in the Diameter MAR command, then the Diameter server
			MUST set the Result-Code AVP value to either:

			1.  DIAMETER_SUCCESS_AUTH_SENT_SERVER_NOT_STORED, if the Diameter
			server is sending authentication credentials to create a
			challenge.

			2.  DIAMETER_SUCCESS_SERVER_NAME_NOT_STORED, if the Diameter server
			successfully authenticated the user and authorized the SIP server
			to proceed with the SIP request.

			Otherwise, the Diameter server MUST set the Result-Code AVP value to
			DIAMETER_UNABLE_TO_COMPLY, and it MUST NOT include any
			SIP-Auth-Data-Item AVP.

			The Message Format of the MAA command is as follows:

		/* Server-Assignment-Request (SAR) Command */
		{
			/*
			
			The Server-Assignment-Request (SAR) command is indicated by the
			Command-Code set to 284 and the Command Flags' 'R' bit set.  The
			Diameter client in a SIP server sends this command to the Diameter
			server to indicate the completion of the authentication process and
			to request that the Diameter server store the URI of the SIP server
			that is currently serving the user.  The main functions of the
			Diameter SAR command are to inform the Diameter server of the URI of
			the SIP server allocated to the user, and to store or clear it from
			the Diameter server.  Additionally, the Diameter client can request
			to download the user profile or part of it.

			During the registration procedure, a SIP server becomes assigned to
			the user.  The Diameter client in the assigned SIP server MUST
			include its own URI in the SIP-Server-URI AVP of the
			Server-Assignment-Request (SAR) Diameter message and send it to the
			Diameter server.  The Diameter server then becomes aware of the
			allocation of the SIP server to the user name and the server's URI.

			The Diameter client in the SIP server MAY send a Diameter SAR message
			because of other reasons.  These reasons are identified in the
			SIP-Server-Assignment-Type AVP (Section 9.4) value.  For instance, a
			Diameter client in a SIP server may contact the Diameter server to
			request deregistration of a user, to inform the Diameter server of an
			authentication failure, or just to download the user profile.  For a
			complete description of all the SIP-Server-Assignment-Type AVP
			values, see Section 9.4.

			Typically the reception of a SIP REGISTER request in a SIP server
			will trigger the Diameter client in the SIP server to send the
			Diameter SAR message.  However, if a SIP server is receiving other
			SIP request, such as INVITE, and the SIP server does not have the
			user profile, the Diameter client in the SIP server may send the
			Diameter SAR message to the Diameter server in order to download the
			user profile and make the Diameter server aware of the SIP server
			assigned to the user.
			The user profile is an important piece of information that dictates
			the behavior of the SIP server when triggering or providing services
			for the user.  Typically the user profile is divided into:

			o  Services to be rendered to the user when the user is registered
			and initiates a SIP request.

			o  Services to be rendered to the user when the user is registered
			and a SIP request destined to that user arrives to the SIP proxy.

			o  Services to be rendered to the user when the user is not
			registered and a SIP request destined to that user arrives to the
			SIP proxy.

			The SIP-Server-Assignment-Type AVP indicates the reason why the
			Diameter client (SIP server) contacted the Diameter server.  If the
			Diameter client sets the SIP-Server-Assignment-Type AVP value to
			REGISTRATION, RE_REGISTRATION, UNREGISTERED_USER, NO_ASSIGNMENT,
			AUTHENTICATION_FAILURE or AUTHENTICATION_TIMEOUT, the Diameter client
			MUST include exactly one SIP-AOR AVP in the Diameter SAR message.

			The SAR message MAY contain zero or more SIP-Supported-User-Data-Type
			AVPs.  Each of them contains a type of user data understood by the
			SIP server.  This allows the Diameter client to provide an indication
			to the Diameter server of the different format of user data
			understood by the SIP server.  The Diameter server uses this
			information to select one or more SIP-User-Data AVPs that will be
			included in the SAA message.

			The Message Format of the SAR command is as follows:

			<SAR> ::= < Diameter Header: 284, REQ, PXY >
				 < Session-Id >
				 { Auth-Application-Id }
				 { Auth-Session-State }
				 { Origin-Host }

			   The Server-Assignment-Answer (SAA) is indicated by the Command-Code
			   set to 284 and the Command Flags' 'R' bit cleared.  The Diameter
			   server sends this command in response to a previously received
			   Diameter Server-Assignment-Request (SAR) command.  The response may
			   include the user profile or part of it, if requested.

			   In addition to the values already defined in RFC 3588 [RFC3588], the
			   Result-Code AVP may contain one of the values defined in
			   Section 10.1.

			   The Result-Code AVP value in the Diameter SAA message may indicate a
			   success or an error in the execution of the Diameter SAR command.  If
			   Result-Code AVP value in the Diameter SAA message does not contain an
			   error code, the SAA message MAY include one or more SIP-User-Data
			   AVPs that typically contain the profile of the user, indicating
			   services that the SIP server can provide to that user.

			   The Diameter server MAY include one or more
			   SIP-Supported-User-Data-Type AVPs, each one identifying a type of
			   user data format supported in the Diameter server.  If there is not a
			   common supported user data type between the Diameter client and the
			   Diameter server, the Diameter server SHOULD declare its list of
			   supported user data types by including one or more
			   SIP-Supported-User-Data-Type AVPs in a Diameter SAA message.  This
			   indication is merely for debugging reasons, since there is not a
			   fallback mechanism that allows the Diameter client to retrieve the
			   profile in a supported format.

			   If the Diameter server requires a User-Name AVP value to process the
			   Diameter SAR request, but the Diameter SAR message did not contain a
			   User-Name AVP value, the Diameter server MUST set the Result-Code AVP
			   value to DIAMETER_USER_NAME_REQUIRED (see Section 10.1.2) and return
			   it in a Diameter SAA message.  Upon reception of this Diameter SAA
			   message with the Result-Code AVP value set to
			   DIAMETER_USER_NAME_REQUIRED, the SIP server typically requests
			   authentication by generating a SIP 401 (Unauthorized) or SIP 407
			   (Proxy Authentication Required) response back to the originator.

			   If the User-Name AVP is included in the Diameter SAR message, upon
			   reception of the Diameter SAR message, the Diameter server MUST
			   verify the existence of the user in the realm, i.e., the User-Name
			   AVP value is a valid user within that realm.  If the Diameter server
			   does not recognize the user name received in the User-Name AVP, the
			   Diameter server MUST build a Diameter Server-Assignment-Answer (SAA)
			   message and MUST set the Result-Code AVP to
			   DIAMETER_ERROR_USER_UNKNOWN.
			   Then the Diameter server MUST authorize that User-Name AVP value is a
			   valid authentication name for the SIP or SIPS URI included in the
			   SIP-AOR AVP of the Diameter SAR message.  If this authorization
			   fails, the Diameter server must set the Result-Code AVP to
			   DIAMETER_ERROR_IDENTITIES_DONT_MATCH and send it in a Diameter
			   Server-Assignment-Answer (SAA) message.

			   After successful execution of the Diameter SAR command, the Diameter
			   server MUST clear the "authentication pending" flag and SHOULD move
			   the temporarily stored SIP server URI to permanent storage.

			   The actions of the Diameter server upon reception of the Diameter SAR
			   message depend on the value of the SIP-Server-Assignment-Type:

			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to REGISTRATION or RE_REGISTRATION, the Diameter
			      server SHOULD verify that there is only one SIP-AOR AVP.
			      Otherwise, the Diameter server MUST answer with a Diameter SAA
			      message with the Result-Code AVP value set to
			      DIAMETER_AVP_OCCURS_TOO_MANY_TIMES and MUST NOT include any
			      SIP-User-Data AVP.  If there is only one SIP-AOR AVP and if the
			      SIP-User-Data-Already-Available AVP value is set to
			      USER_DATA_NOT_AVAILABLE, then the Diameter server SHOULD include
			      one or more user profile data with the SIP or SIPS URI (SIP-AOR
			      AVP) and all other SIP identities associated with that AVP in the
			      SIP-User-Data AVP value of the Diameter SAA message.  On selecting
			      the type of user data, the Diameter server SHOULD take into
			      account the supported formats at the SIP server
			      (SIP-Supported-User-Data-Type AVP in the SAR message) and the
			      local policy.  Additionally, the Diameter server MUST set the
			      Result-Code AVP value to DIAMETER_SUCCESS in the Diameter SAA
			      message.  The Diameter server considers the SIP AOR authenticated
			      and registered.

			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to UNREGISTERED_USER, then the Diameter server MUST
			      store the SIP server address included in the SIP-Server-URI AVP
			      value.  The Diameter server will return the SIP server address in
			      Diameter Location-Info-Answer (LIA) messages.  If the
			      SIP-User-Data-Already-Available AVP value is set to
			      USER_DATA_NOT_AVAILABLE, then the Diameter server SHOULD include
			      one or more user profile data associated with the SIP or SIPS URI
			      (SIP-AOR AVP) and associated identities in the SIP-User-Data AVP
			      value of the Diameter SAA message.  On selecting the type of user
			      data, the Diameter server SHOULD take into account the supported
			      formats at the SIP server (SIP-Supported-User-Data-Type AVP in the
			      SAR message) and the local policy.  The Diameter server MUST set
			      the Result-Code AVP value to DIAMETER_SUCCESS.  The Diameter
			      server considers the SIP AOR UNREGISTERED, but with a SIP server
			      allocated to trigger and provide services for unregistered users.
			      Note that in case of UNREGISTERED_USER (SIP-Server-Assignment-Type
			      AVP), the Diameter server MUST verify that there is only one
			      SIP-AOR AVP.  Otherwise, the Diameter server MUST answer the
			      Diameter SAR message with a Diameter SAA message, and it MUST set
			      the Result-Code AVP value to DIAMETER_AVP_OCCURS_TOO_MANY_TIMES
			      and MUST NOT include any SIP-User-Data AVP.
			      If the User-Name AVP was not present in the Diameter SAR message
			      and the SIP-AOR is not known for the Diameter server, the Diameter
			      server MUST NOT include a User-Name AVP in the Diameter SAA
			      message and MUST set the Result-Code AVP value to
			      DIAMETER_ERROR_USER_UNKNOWN.

			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to TIMEOUT_DEREGISTRATION, USER_DEREGISTRATION,
			      DEREGISTRATION_TOO_MUCH_DATA, or ADMINISTRATIVE_DEREGISTRATION,
			      the Diameter server MUST clear the SIP server address associated
			      with all SIP AORs indicated in each of the SIP-AOR AVP values
			      included in the Diameter SAR message.  The Diameter server
			      considers all of these SIP AORs as not registered.  The Diameter
			      server MUST set the Result-Code AVP value to DIAMETER_SUCCESS in
			      the Diameter SAA message.

			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to TIMEOUT_DEREGISTRATION_STORE_SERVER_NAME or
			      USER_DEREGISTRATION_STORE_SERVER_NAME, the Diameter server MAY
			      keep the SIP server address associated with the SIP AORs included
			      in the SIP-AOR AVP values of the Diameter SAR message, even though
			      the SIP AORs become unregistered.  This feature allows a SIP
			      server to request that the Diameter server remain an assigned SIP
			      server for those SIP AORs (SIP-AOR AVP values) allocated to the
			      same user name, and avoid SIP server assignment.  The Diameter
			      server MUST consider all these SIP AORs as not registered.  If the
			      Diameter server honors the request of the Diameter client (SIP
			      server) to remain as an allocated SIP server, then the Diameter
			      server MUST keep the SIP server assigned to those SIP AORs
			      allocated to the username and MUST set the Result-Code AVP value
			      to DIAMETER_SUCCESS in the Diameter SAA message.  Otherwise, when
			      the Diameter server does not honor the request of the Diameter
			      client (SIP server) to remain as an allocated SIP server, the
			      Diameter server MUST clear the SIP server name assigned to those
			      SIP AORs and it MUST set the Result-Code AVP value to
			      DIAMETER_SUCCESS_SERVER_NAME_NOT_STORED in the Diameter SAA
			      message.
			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to NO_ASSIGNMENT, the Diameter server SHOULD first
			      verify that the SIP-Server-URI AVP value in the Diameter SAR
			      message is the same URI as the one assigned to the SIP-AOR AVP
			      value.  If they differ, then the Diameter server MUST set the
			      Result-Code AVP value to DIAMETER_UNABLE_TO_COMPLY in the Diameter
			      SAA message.  Otherwise, if the SIP-User-Data-Already-Available
			      AVP value is set to USER_DATA_NOT_AVAILABLE, then the Diameter
			      server SHOULD include the user profile data with the SIP or SIPS
			      URI (SIP-AOR AVP) and all other SIP identities associated with
			      that AVP in the SIP-User-Data AVP value of the Diameter SAA
			      message.  On selecting the type of user data, the Diameter server
			      SHOULD take into account the supported formats at the SIP server
			      (SIP-Supported-User-Data-Type AVP in the SAR message) and the
			      local policy.

			   o  If the SIP-Server-Assignment-Type AVP value in the Diameter SAR
			      message is set to AUTHENTICATION_FAILURE or
			      AUTHENTICATION_TIMEOUT, the Diameter server MUST verify that there
			      is exactly one SIP-AOR AVP in the Diameter SAR message.  If the
			      number of occurrences of the SIP-AOR AVP is not exactly one, the
			      Diameter server MUST set the Result-Code AVP value to
			      DIAMETER_AVP_OCCURS_TOO_MANY_TIMES in the Diameter SAA message,
			      and SHOULD not take further actions.  If there is exactly one
			      SIP-AOR AVP in the Diameter SAR message, the Diameter server MUST
			      clear the address of the SIP server assigned to the SIP AOR
			      allocated to the user name, and the Diameter server MUST set the
			      Result-Code AVP value to DIAMETER_SUCCESS in the Diameter SAA
			      message.  The Diameter server MUST consider the SIP AOR as not
			      registered.

			   The Message Format of the SAA command is as follows:

			   Location-Info-Request (LIR) command.

			   In addition to the values already defined in RFC 3588 [RFC3588], the
			   Result-Code AVP may contain one of the values defined in
			   Section 10.1.  When the Diameter server finds an error in processing
			   the Diameter LIR message, the Diameter server MUST stop the process
			   of the message and answer with a Diameter LIA message that includes
			   the appropriate error code in the Result-Code AVP value.  When there
			   is no error, the Diameter server MUST set the Result-Code AVP value
			   to DIAMETER_SUCCESS in the Diameter LIA message.

			   One of the errors that the Diameter server may find is that the
			   SIP-AOR AVP value is not a valid user in the realm.  In such cases,
			   the Diameter server MUST set the Result-Code AVP value to
			   DIAMETER_ERROR_USER_UNKNOWN and return it in a Diameter LIA message.

			   If the Diameter server cannot process the Diameter LIR command, e.g.,
			   due to a database error, the Diameter server MUST set the Result-Code
			   AVP value to DIAMETER_UNABLE_TO_COMPLY and return it in a Diameter
			   LIA message.  The Diameter server MUST NOT include any SIP-Server-URI
			   or SIP-Server-Capabilities AVP in the Diameter LIA message.

			   The Diameter server may or may not be aware of a SIP server assigned
			   to the SIP-AOR AVP value included in the Diameter LIR message.  If
			   the Diameter server is aware of a SIP server allocated to that
			   particular user, the Diameter server MUST include the URI of such SIP
			   server in the SIP-Server-URI AVP and return it in a Diameter LIA
			   message.  This is typically the situation when the user is either
			   registered, or unregistered but a SIP server is still assigned to the
			   user.

			   When the Diameter server is not aware of a SIP server allocated to
			   the user (typically the case when the user unregistered), the
			   Result-Code AVP value in the Diameter LIA message depends on whether
			   the Diameter server is aware that the user has services defined for
			   unregistered users:

			   o  Those users who have services defined for unregistered users may
			      require the allocation of a SIP server to trigger and perhaps
			      execute those services.  Therefore, when the Diameter server is
			      not aware of an assigned SIP server, but the user has services
			      defined for unregistered users, the Diameter server MUST set the
			      Result-Code AVP value to DIAMETER_UNREGISTERED_SERVICE and return
			      it in a Diameter LIA message.  The Diameter server MAY also
			      include a SIP-Server-Capabilities AVP to facilitate the SIP server
			      (Diameter client) with the selection of an appropriate SIP server
			      with the required capabilities.  Absence of the SIP-Server-
			      Capabilities AVP indicates to the SIP server (Diameter client)
			      that any SIP server is suitable to be allocated for the user.

			   o  Those users who do not have service defined for unregistered users
			      do not require further processing.  The Diameter server MUST set
			      the Result-Code AVP value to
			      DIAMETER_ERROR_IDENTITY_NOT_REGISTERED and return it to the
			      Diameter client in a Diameter LIA message.  The SIP server
			      (Diameter client) may return the appropriate SIP response (e.g.,
			      480 (Temporarily unavailable)) to the original SIP request.

			   If the SIP server (Diameter client) requires a User-Name AVP value to

			   10.1.2) and return it in a Diameter RTA message.

			   The SIP server (Diameter client) applies the administrative

			   The value of the SIP-Deregistration-Reason AVP in the Diameter RTR
			   command has an effect on the actions performed at the SIP server

			   o  If the value is set to PERMANENT_TERMINATION, then the user has

			      so.  The Diameter Client in the SIP Server SHOULD NOT request a
			      new user registration.  The SIP server clears the registration
			      state of the deregistered AORs.

			   o  If the value is set to NEW_SIP_SERVER_ASSIGNED, the Diameter
			      server informs the SIP server (Diameter client) that a new SIP
			      server has been allocated to the user, due to some reason.  The
			      SIP server, if supported through SIP procedures, will inform the
			      interested parties (e.g., subscribers to the "reg" event
			      [RFC3680]) about the administrative deregistration at this SIP
			      server.  The Diameter client in the SIP server SHOULD NOT request
			      a new user registration.  The SIP server clears the registration
			      state of the deregistered SIP AORs.

			   o  If the value is set to SIP_SERVER_CHANGE, the Diameter server
			      informs the SIP server (Diameter client) that a new SIP server has
			      to be allocated to the user, e.g., due to user's capabilities
			      requiring a new SIP server, or not enough resources in the current
			      SIP server.  If informing the interested parties about the
			      administrative deregistration is supported through SIP procedures
			      (e.g., subscriptions to the "reg" event [RFC3680]), the SIP server
			      will do so.  The Diameter client in the SIP Server SHOULD NOT
			      request a new user registration.  The SIP server clears the
			      registration state of the deregistered SIP AORs.

			   o  If the value is set to REMOVE_SIP_SERVER, the Diameter server
			      informs the SIP server (Diameter client) that the SIP server will
			      no longer be bound in the Diameter server with that user.  The SIP
