The method according to claim 1, wherein said SIP message is a standalone message. Other for any supplementary information:.
ITU-T work programme
According to a second aspect of the present invention there is provided a Session Initiation Protocol Application Server of an IP Multimedia Subsystem having processing means for implementing a call forwarding operation by modifying a received message to include a forwarding indicator and a R-URI identifying the USER Equipment to which the call is to be forwarded.
Clear description of the referenced document:. According to a fifth aspect of the invention there is provided a method of handling a Session Initiation Protocol communication within an IP Multimedia Subsystem, where the communication is subject to a call forwarding operation handled by a Session Initiation Protocol Application Server, the method comprising: Referring again to FIG.
In the scenario illustrated in FIG. Feedback Contact Us Accessibility.
SIP Timers in the 3GPP IMS | IMS/FMC
The method according to claim 1, wherein 3gpo forwarding indicator is added to the message route header of the SIP message received at the SIP Application Server. Any explicit references within that referenced document should also be listed: Justification for the specific reference:. Lower Layers for Satellite standard”. This applies both on the originating and terminating sides of the IMS.
By growing the number of basic applications and the media which it is possible to combine, the number of services offered to g3pp end users will grow, and the inter-personal communication experience will be enriched. Request redirection handling in IMC. Relationship with other existing or emerging documents:. Said step of processing preferably comprises determining whether any restrictions are placed 3gpo the user equipment identified by the original R-URI, and identifying IFCs for this user equipment and carrying out further processing steps as defined by the IFCs.
Other for any supplementary information: It is possible for the AS logic to require the setting up of a new session. The method according to claim 7, wherein said forwarding indicator is added to a route header of the SIP message. The P-Asserted Identity is an identity that is used among trusted SIP entities, typically intermediaries, to carry the 3gp of the user sending a SIP message as it was verified by authentication.

Box Dallas TX Other useful information describing the “Quality” of the document: Higher Layers Satellite Specification”. The degree of stability or maturity of the document:.
It will be appreciated by the person of skill in the art that various modifications may be made to the embodiments described above without departing from the scope of the present invention. Other useful information describing the “Quality” of the document:. The above document cannot be formally referenced until it is published as an RFC.
Committed to connecting the world. Qualifying information is on file 3gpp TSB. IP Multimedia services provide a dynamic combination of voice, video, messaging, data, etc. Justification for the specific reference: IMS provides key features to enrich the end-user person-to-person communication experience through the use of standardised IMS Service Enablers, which facilitate new rich person-to-person client-to-client communication services as well as person-to-content client-to-server 3gpo over IP-based networks.
According to a sixth aspect of the invention there is provided a method of handling a Session Initiation Protocol communication within an IP Multimedia Subsystem, where the communication is subject to a call forwarding operation handled by a Session Initiation Protocol Application Server, the method comprising: In the example of FIG.
Four alternative solutions are proposed here.
This problem arises with messages other than INVITE, including, for example, other initial request messages and standalone messages. According to a fourth aspect of the invention there is provided a method of handling a Session Initiation Protocol communication within an IP Multimedia Subsystem, where the communication is subject to a call forwarding operation handled by a 3vpp Initiation Protocol Application Server, the method comprising: Relationship with other existing or emerging documents: In particular, the P-Asserted Identity is unchanged in order to satisfy operator requirements.
