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. ## Claims ### Claim 1 A method for providing information to an Application Server (AS) by a network component, the method comprising: receiving, from a user equipment (UE), a Session Initiation Protocol (SIP) Register message; determining whether filter criteria indicate a need for a new SIP message, and further determining whether the filter criteria indicate the new SIP message is to comprise at least one of the SIP Register message as a whole or a SIP response message, wherein the determinations are responsive to reception of the SIP Register message; and including a Multi-purpose Internet Mail Extensions (MIME) body in the body of the new SIP message, the MIME body including at least one of the SIP Register message as a whole or the SIP response message. ### Claim 2 (depends on 1) The method of claim 1, further comprising sending the new SIP message to the AS. ### Claim 3 (depends on 2) The method of claim 2, wherein the received SIP Register message comprises a first request uniform resource identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the new SIP message comprises a second Request URI, the second Request URI comprising an address of the AS. ### Claim 4 (depends on 1) The method of claim 1, further comprising downloading a user profile to the network component. ### Claim 5 (depends on 4) The method of claim 4, wherein the user profile comprises the filter criteria. ### Claim 6 (depends on 1) The method of claim 1, wherein the included SIP response message is a copy of a SIP 200 OK message sent to the UE in response to the SIP Register message. ### Claim 7 (depends on 1) The method of claim 1, further comprising including as a contact header field the request uniform resource identifier (R-URI) of the network entity. ### Claim 8 (depends on 1) The method of claim 1, wherein the new SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event, and the new SIP message contains the SIP Register message as a whole. ### Claim 9 (depends on 1) The method of claim 1, wherein the “To:” field of the new SIP message contains an identifier of the UE, and wherein the “From:” field of the new SIP message contains an identifier of the network entity. ### Claim 10 (depends on 1) The method of claim 1, wherein the network component is a serving call session control function. ### Claim 11 A component in a telecommunications network, the component comprising: a processor configured to: receive a Session Initiation Protocol (SIP) Register message from a user equipment (UE); determine whether filter criteria indicate a need for a new SIP message, and further determine whether the filter criteria indicate the new SIP message is to comprise at least one of the SIP Register message as a whole or a SIP response message, wherein the determinations are responsive to reception of the SIP Register message; and include a Multi-purpose Internet Mail Extensions (MIME) body in the body of the new SIP message, the MIME body including at least one of the SIP Register message as a whole or the SIP response message. ### Claim 12 (depends on 11) The component of claim 11, wherein the processor is further configured to send the new SIP message to an Application Server (AS). ### Claim 13 (depends on 12) The component of claim 12, wherein the received SIP Register message comprises a first request uniform resource identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the new SIP message comprises a second Request URI, the second Request URI comprising an address of the AS. ### Claim 14 (depends on 11) The component of claim 11, wherein the processor is further configured to download a user profile to the network component. ### Claim 15 (depends on 14) The component of claim 14, wherein the user profile comprises the filter criteria. ### Claim 16 (depends on 11) The component of claim 11, wherein the included SIP response message is a copy of a SIP 200 OK message sent to the UE in response to the SIP Register message. ### Claim 17 (depends on 11) The component of claim 11, wherein the new SIP message is a SIP NOTIFY message containing a registration event package transmitted as a result of a registration event, and the new SIP message contains the SIP Register message as a whole. ### Claim 18 (depends on 11) The component of claim 11, wherein the component is a serving call session control function. ### Claim 19 A non-transitory computer readable medium storing computer readable instructions, the computer readable instructions adapted to be executed by a processor to implement a method for providing information to an Application Server (AS), the method comprising: the processor receiving, from a user equipment (UE), a Session Initiation Protocol (SIP) Register message; the processor determining whether filter criteria indicate a need for a new SIP message, and further determining whether the filter criteria indicate the new SIP message is to comprise at least one of the SIP Register message as a whole or a SIP response message, wherein the determinations are responsive to reception of the SIP Register message; and the processor including a Multi-purpose Internet Mail Extensions (MIME) body in the body of the new SIP message, the MIME body including at least one of the SIP Register message as a whole or a SIP response message, wherein the received SIP Register message comprises a first Request Uniform Resource Identifier (Request URI), the first Request URI comprising a SIP registrar address, and wherein the new SIP message comprises a second Request URI, the second Request URI comprising an address of the AS. ### Claim 20 (depends on 19) The non-transitory computer readable medium of claim 19, wherein the method further comprises the processor downloading a user profile, wherein the user profile comprises the filter criteria.
