SIP Preconditions have an impact on call success rate and post dialing delay.
ITU-T A.5 reference justification
Relationship with other existing or emerging documents:. The method according to claim 1, wherein said forwarding indicator is added to the message route header of the SIP message received at the SIP Application Server. The degree of stability or maturity of the document:. Qualifying information is on file at TSB. The invention is applicable in particular to Session Initiation Protocol initial request messages, e.
Other solutions to this problem must therefore be sought. Click for automatic bibliography generation. Higher Layers Satellite Specification”. Any explicit references within that referenced document should also be listed: Overview and System Level specification”.
Said step of processing preferably comprises determining whether any restrictions are placed on 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. 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: United States Patent The degree of stability or maturity of the document: Referring again to FIG.
By growing the number of basic applications and the media which it is possible to combine, the number of services offered to the end users will grow, and the inter-personal communication experience will be enriched. 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.
Current information, if any, about IPR issues: Clear description of the referenced document:. A SumoBrain Solutions Company.
ITU-T work programme
Current information, if any, about IPR issues:. Other for any supplementary information:. 33gpp to connecting the world. Other useful information describing the “Quality” of the document: Basic and Digest Access Authentication”. 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: 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 services over IP-based networks.
Preferably, said forwarding indicator is contained in the route header. Whilst SIP was created as a user-to-user protocol, IMS allows operators and service providers to control user access to services and to charge users accordingly.
The method 3gppp to claim 7, wherein said forwarding indicator is added to a route header of the SIP message. The invention claimed is: However, this is unlikely to be accepted by operators who will prefer to leave the P-Asserted Identity unchanged from end-to-end.
Other for any supplementary information: Ts224.229 P-Asserted Identity is an identity that is used among trusted SIP entities, typically intermediaries, to carry the identity of the user sending a SIP message as it was verified by authentication.
Request redirection handling in IMC. Any explicit references within that referenced document should also be listed:. In the example of FIG. In the scenario illustrated in FIG. This applies both on the originating and terminating sides of the T24.229. This may be mapped against the ODI.
