Abstract

A system, server and method of executing originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS.

Claims

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 carrier gateway server configured to operate as an IMS-compliant SIP application server (SIP-AS); and

an enterprise gateway server, wherein the enterprise gateway server is configured to act as at least one of an IMS-compliant proxy call session control function (P-CSCF), interrogating call session control function (I-CSCF), and a serving call session control function (S-CSCF), and manage an incoming call log and order the carrier gateway server to originate an outgoing call leg to a subscriber'"'"'s mobile phone with a calling identify of a calling party to indicate which line was called, wherein the carrier gateway server is configured to

communicate with the enterprise gateway server,

prepare the enterprise gateway server for an upcoming communication,

respond to a serving call session control function (S-CSCF), and route the session to a destination in the terminating IMS network, wherein the enterprise gateway server is configured to

receive the session in the terminating IMS network,

act as at least one of a S-CSCF and an I-CSCF, wherein the I-CSCF is configured

to route the session for handling during session setup,

act as a S-CSCF front-end (FE) which is configured to convert a terminating services request, received during the session setup, to an originating services request prior to communicating with a terminating service associated with a terminating network application, and

once the outgoing call leg is established, connect the outgoing call leg to the incoming call leg in the control of the enterprise gateway server.

2. The system as specified in claim 1 wherein the FE is configured to convert IMS messaging into a corresponding SIP-AS service-invocation message and operate with a non-IMS application.

3. The system as specified in claim 2 wherein the enterprise gateway server is configured to enable a non-IMS application to perform terminating services once the originating services have been executed.

4. The system as specified in claim 2 wherein the enterprise gateway server is configured to act as an S-CSCF front-end to an IMS-compliant application, whereby the FE is configured to convert the terminating services request to an originating services request prior to communicating with the IMS-compliant application.

5. The system as specified in claim 2 wherein the system is configured such that following a successful execution of the originating services of an IMS-compliant application, the IMS-compliant application can return control to the FE to invoke another service request back to the IMS-compliant application to perform terminating services.

6. A carrier gateway server configured to execute originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, the carrier gateway server configured to:

operate as an IMS-compliant SIP application server (SIP-AS) communicating with a terminating enterprise gateway server acting as a at least one of an IMS-compliant proxy call session control function (P-CSCF), an interrogating call session control function (I-CSCF) and a serving call session control function (S-CSCF), and supporting at least one of a legacy, hybrid and IP private branch exchange (PBX) located in an enterprise, and wherein the enterprise gateway server manages an incoming call leg and orders the carrier gateway server to originate an outgoing call leg to a subscriber'"'"'s mobile phone with a calling identify number of a calling party to indicate which line was called;

prepare the enterprise gateway server for an upcoming communication;

respond to a serving call session control function (S-CSCF), and wherein the carrier gateway server is configured to route the session to a destination in the terminating IMS network during session setup; and

wherein the enterprise gateway server is configured to act as a S-CSCF front-end (FE) which is configured to convert a terminating services request, received during the session setup, to an originating services request prior to communicating with a terminating service associated with a terminating network application, and

once the outgoing call leg is established, connect the outgoing call leg to the incoming call leg in the control of the enterprise gateway server.

7. An enterprise gateway server configured to execute originating services in a terminating IP Multimedia Subsystem (IMS) network in which a triggered application may or may not support IMS, the enterprise gateway server configured to:

receive a session in the terminating IMS network; and

act as at least one of a proxy call session control function (P-CSCF), an interrogating call session control function (I-CSCF), and a serving call session control function (S-CSCF),

manage an incoming call leg and order the carrier gateway server to originate an outgoing call leg to a subscriber'"'"'s mobile phone with a calling identify of a calling party to indicate which line was called,

wherein the I-CSCF is configured to route the session for handling via a carrier gateway server configured to operate as an IMS-compliant SIP application server (SIP-AS), and

wherein the enterprise gateway server is configured to communicate with the carrier gateway server to prepare the carrier gateway server for an upcoming communication during session setup, and once the outgoing call leg is established, have the carrier gateway server connect the outgoing call leg to the incoming call leg in the control of the enterprise gateway server; and

act as a S-CSCF front-end (FE) which is configured to convert a terminating services request, received during the session setup, to an originating services request prior to communicating with a terminating service associated with a terminating network application.

8. 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:

configuring a carrier gateway server to act as an IMS-compliant SIP application server (SIP-AS);

communicating, by the carrier gateway server, with a terminating enterprise gateway server configured to act as a at least one of an IMS-compliant proxy call session control function (P-CSCF), an interrogating call session control function (I-CSCF) and a serving call session control function (S-CSCF) that is configured to support at least one of a legacy, hybrid and IP private branch exchange (PBX) located in an enterprise, and managing an incoming call leg and ordering the carrier gateway server to originate an outgoing call leg to a subscriber'"'"'s mobile phone with a calling identity of a calling party to indicate which line was called;

responding, by the carrier gateway server, to a serving call session control function (S-CSCF) which routes a session to a destination in the terminating IMS network;

receiving, by the enterprise gateway server, the session in the terminating IMS network; and

routing by the enterprise gateway server the session wherein during session setup, the enterprise gateway server acts as a S-CSCF front-end (FE) for converting a terminating services request, received during the session setup, to an originating services request prior to communicating with a terminating service associated with a terminating network application, and once the outgoing call leg is established, the carrier gateway server connects the outgoing call leg to the incoming call leg in the control of the enterprise gateway server.

9. The method as specified in claim 8, the method additionally comprising:

converting, by the front end, IMS messaging into a corresponding SIP-AS service-invocation message of the non-IMS application.

10. The method as specified in claim 9 wherein the enterprise gateway server enables the non-IMS application to perform terminating services once the originating services have been executed.

11. The method as specified in claim 9 wherein the FE converts the terminating services request to an originating services request prior to communicating with the IMS compliant application.

12. The method as specified in claim 9 wherein following a successful execution of the originating services of an IMS-compliant application, the IMS-compliant application returns control to the FE to invoke another service request back to the IMS-compliant application to perform terminating services.
