+ 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: 300, REQ, PXY, 16777216 >
+ < Session-Id >
+ { Vendor-Specific-Application-Id }

+ {
+ /*
+ 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
+ Command-Code set to 286 and the Command Flags' 'R' bit set. The
+ Diameter client in a SIP server sends this command to the Diameter
+ 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-

+
+ 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.

+
+ If the Diameter server requires a User-Name AVP value to process the

+ 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

+ /*
+
+ 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 Result-Code AVP value in the Diameter SAA message may indicate a

+
+ The Diameter server MAY include one or more

+
+ If the Diameter server requires a User-Name AVP value to process the

+ 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

+
+ 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

+ 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

+ sends this command in response to a previously received Diameter
+ 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.,

+
+ 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
