System and method for executing originating services in a terminating network for IMS and non-IMS applications
First Claim
Patent Images
1. A system configured to execute originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, comprising;
- a) a carrier or cellular gateway server (GS-C) configured to operate as an IMS-compliant SIP application server (SIP-AS) communicating with a terminating network gateway server (GS-E) located in an enterprise via a direct signaling connection, the GS-C configured to prepare the GS-E for an upcoming communication;
b) the GS-C configured to operate as an IMS-compliant SIP application server (SIP-AS) responding to a serving CSCF (S-CSCF) and configured to route the session to a destination in the terminating IMS network;
c) the GS-E configured to receive the session in the terminating IMS network and act as an IMS-compliant interrogating CSCF (I-CSCF); and
d) the GS-E configured to act as an IMS-compliant S-CSCF, wherein the I-CSCF is configured to route the session for handling.

7. A carrier gateway server (GS-C) configured to execute originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, comprising;
-
a) the GS-C configured to operate as an IMS-compliant SIP application server (SIP-AS) communicating with a terminating network gateway server (GS-E) supporting a legacy, hybrid and/or IP PBX and located in an enterprise via a direct signaling connection, the GS-C configured to prepare the GS-E for an upcoming communication; and b) the GS-C configured to operate as an IMS-compliant SIP application server (SIP-AS) responding to the serving CSCF (S-CSCF) and configured to route the session to a destination in the terminating IMS network.

8. An enterprise gateway server (GS-E) configured to execute originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, comprising;
-
a) the GS-E configured to receive the session in the terminating IMS network and act as an IMS-compliant interrogating CSCF (I-CSCF); and b) the GS-E configured to act as an IMS-compliant S-CSCF, wherein the I-CSCF is configured to route the session for handling.

9. A method for executing originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, comprising the steps of;
-
a) a carrier gateway server (GS-C) acting as an IMS-compliant SIP application server (SIP-AS) communicating with a terminating network gateway server (GS-E) that is supporting a legacy, hybrid and/or IP PBX and located in an enterprise via a direct signaling connection to prepare the GS-E for an upcoming communication; b) the GS-C acting as an IMS-compliant SIP application server (SIP-AS) responding to the serving CSCF (S-CSCF) which routes the session to the destination in the terminating IMS network; c) the GS-E receiving the session in the terminating IMS network acting as an IMS-compliant interrogating CSCF (I-CSCP); and d) the GS-E acting as an IMS-compliant S-CSCF, to which the I-CSCF routes the session for handling. - View Dependent Claims (10, 11, 12, 13, 14)
