Providing session initiation protocol request contents method and system
An embodiment provides a user equipment that includes a processor configured to receive a Session Initiation Protocol (SIP) NOTIFY message transmitted by a network component as a result of a registration event. The SIP NOTIFY message contains at least a portion of information included in a first SIP message sent between a first user equipment and the network component. Another embodiment provides method and apparatus for a network node to determine whether filter criteria include one or more indicators that specify the need for information, and including in a second SIP message the information specified by the one or more indicators.
1. A Call Session Control Function (CSCF) for providing information regarding a first entity, the CSCF comprising:
a processor configured to send a session initiation protocol (SIP) message to a second entity, the SIP message including a message,
wherein the message comprises a first request uniform resource identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the SIP message comprises a second Request URI, the second Request URI comprising an address of the second entity.
2. The CSCF of claim 1 , wherein the second entity comprises an application server (AS).
3. The CSCF of claim 1 , wherein the SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event.
4. The CSCF of claim 1 , wherein the message includes at least an initial line and a header field.
5. The CSCF of claim 1 , wherein the message is sent from the CSCF or received by the CSCF.
6. The CSCF of claim 1 , wherein the message is a copy of a SIP 200 OK message sent by the first entity or the second entity.
7. The CSCF of claim 1 , wherein the SIP message comprises a Multi-purpose Internet Mail Extensions (MIME) body including at least one of a SIP Register message as a whole or a SIP Response message as a whole.
8. A method for providing information regarding a first entity, the method comprising:
sending, by a Call Session Control Function (CSCF), a session initiation protocol (SIP) message to a second entity, the SIP message including a message,
wherein the message comprises a first request uniform resource identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the SIP message comprises a second Request URI, the second Request URI comprising an address of the second entity.
9. The method of claim 8 , wherein the second entity comprises an application server (AS).
10. The method of claim 9 , wherein the message includes at least an initial line and a header field, and wherein the AS is configured to obtain the information from the initial line or the header field.
11. The method of claim 8 , wherein the SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event.
12. The method of claim 8 , wherein the message is sent from the CSCF or received by the CSCF.
13. The method of claim 8 , wherein the message is a copy of a SIP 200 OK message sent by the first entity or the second entity.
14. The method of claim 8 , wherein the SIP message comprises a Multi-purpose Internet Mail Extensions (MIME) body including at least one of a SIP Register message as a whole or a SIP Response message as a whole.
15. A non-transitory computer readable medium storing computer readable instructions executable by a processor to implement a method for providing information regarding a first entity, the method comprising:
sending, by a Call Session Control Function (CSCF), a session initiation protocol (SIP) message to a second entity, the SIP message including a message,
wherein the message comprises a first request uniform resource identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the SIP message comprises a second Request URI, the second Request URI comprising an address of the second entity.
16. The non-transitory computer readable medium of claim 15 , wherein the second entity comprises an application server (AS).
17. The non-transitory computer readable medium of claim 16 , wherein the message includes at least an initial line and a header field, and wherein the AS is configured to obtain the information from the initial line or the header field.
18. The non-transitory computer readable medium of claim 15 , wherein the SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event.
19. The non-transitory computer readable medium of claim 15 , wherein message is sent from the CSCF or received by the CSCF.
20. The non-transitory computer readable medium of claim 15 , wherein the SIP message comprises a Multi-purpose Internet Mail Extensions (MIME) body including at least one of a SIP Register message as a whole or a SIP Response message as a whole.
