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. An Application Server (AS) for obtaining information regarding a first entity, the AS comprising:
a processor configured to receive a session initiation protocol (SIP) message from a second entity, the SIP message including a first message that was received by the second entity from the first entity or a second message that was sent from the second entity towards the first entity,
wherein the processor is further configured to obtain the information that was included by the first entity from the first message or that was sent towards the first entity in the second message,
wherein at least one of the first message or the second 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 AS.
2. The AS 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.
3. The AS of claim 1 , wherein at least one of the first message or the second message includes at least an initial line and a header field, and wherein the AS obtains the information from the initial line or the header field.
4. The AS of claim 1 , wherein the SIP message is received from a Serving Call-State Control-Function (S-CSCF).
5. The AS of claim 1 , wherein the second message is a copy of a SIP 200 OK message sent from the second entity towards the first entity in response to the first message received by the second entity from the first entity.
6. The AS 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.
7. A method for obtaining information regarding a first entity, the method comprising:
receiving, at an Application Server (AS), a session initiation protocol (SIP) message from a second entity, the SIP message including a first message that was received by the second entity from the first entity or a second message that was sent from the second entity towards the first entity; and
obtaining the information that was included by the first entity from the first message or that was sent towards the first entity in the second message,
wherein at least one of the first message or the second 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 AS.
8. The method of claim 7 , wherein the SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event.
9. The method of claim 7 , wherein at least one of the first message or the second message includes at least an initial line and a header field, and wherein the AS obtains the information from the initial line or the header field.
10. The method of claim 7 , wherein the SIP message is received from a Serving Call-State Control-Function (S-CSCF).
11. The method of claim 7 , wherein the second message is a copy of a SIP 200 OK message sent from the second entity towards the first entity in response to the first message received by the second entity from the first entity.
12. A non-transitory computer readable medium storing computer readable instructions executable by a processor to implement a method for obtaining information regarding a first entity, the method comprising:
receiving, at an Application Server (AS), a session initiation protocol (SIP) message from a second entity, the SIP message including a first message that was received by the second entity from the first entity or a second message that was sent from the second entity towards the first entity; and
obtaining the information that was included by the first entity from the first message or that was sent towards the first entity in the second message,
wherein at least one of the first message or the second 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 address of the AS.
13. The non-transitory computer readable medium of claim 12 , wherein the SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event.
14. The non-transitory computer readable medium of claim 12 , wherein at least one of the first message or the second message includes at least an initial line and a header field, and wherein the AS obtains the information from the initial line or the header field.
15. The non-transitory computer readable medium of claim 12 , wherein the second message is a copy of a SIP 200 OK message sent from the second entity towards the first entity in response to the first message received by the second entity from the first entity.
