Mobile access terminal with local call session control function
First Claim
1. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of accessing an application service from a mobile access terminal (MAT) via an internet protocol multimedia subsystem (IMS) network associated with a service provider, the method comprising:
- starting an application-service client on the MAT, the application-service client comprising a client program that communicates with an application server to facilitate access to an application service located in the application server;
invoking a local Call Session Control Function (CSCF) server on the MAT, the local CSCF server comprising one or more features of a Serving Call Session Control Function (S-CSCF), the local CSCF server interacts, according to a predetermined relationship, with an S-CSCF hosted by the IMS network to facilitate access to the application service by the MAT, wherein the predetermined relationship is determined in advance based on a specification of the MAT that defines the one or more features of the S-CSCF executable on the MAT;
creating a local control interface on the MAT, the local control interface comprising one or more features of an IMS Service Control (ISC) interface, wherein the local control interface facilitates interaction between the local CSCF server and the application-service client; and
interacting with the S-CSCF associated with the IMS network to facilitate access to the application service.

Abstract
A computing device, computing system, method, and medium are provided for utilizing a local Call Session Control Function (CSCF) server located on a mobile access terminal to facilitate access to application services hosted by an application server. An application-service client corresponding to the application server is instantiated on the mobile access terminal and interacts with the local CSCF server via a local control interface. The local CSCF server includes features of a Serving Call Session Control Function (S-CSCF), and thereby enables authentication, interoperability testing, and control functions to be performed in the operating environment on the MAT. The local CSCF server interacts according to a predetermined relationship with an S-CSCF on the IMS network to facilitate access to application services.

8. A mobile access terminal (MAT) capable of accessing an application service hosted by an application server via an internet protocol multimedia system (IMS) network, the MAT comprising a communications device having a system bus that couples a plurality of system components, the plurality of system components comprising:
-
a display device; a processor that executes computer-executable instructions read from computer-readable media; and computer-readable media that stores computer-readable instructions, the computer-readable instructions comprising; (a) a local Call Session Control Function (CSCF) server that runs on the MAT, the local CSCF server comprising one or more features of a Serving Call Session Control Function (S-CSCF), wherein the local CSCF server interacts, according to a predetermined relationship, with a Serving Call Session Control Function (S-CSCF) hosted by the IMS network to facilitate access to the application service, wherein the predetermined relationship is determined in advance based on a specification of the MAT that defines the one or more features of the S-CSCF executable on the MAT; (b) an application-service client that runs on the MAT, wherein the application-service client communicates with an application server to facilitate access to an application service hosted by an application server, wherein the application-service client is developed, at least in part, based on the specification of the MAT that defines the one or more features of the S-CSCF executable on the MAT; and (c) a local control interface that facilitates interaction between the local CSCF server and the application-service client to facilitate access to the application service. - View Dependent Claims (9, 10, 11, 12, 13)

14. One or more non-transitory computer-readable media having computer-executable instructions embodied thereon for performing a method of using a local Call Session Control Function (CSCF) server running on a mobile access terminal (MAT) to access an application service via an internet protocol multimedia subsystem (IMS) network, the method comprising:
-
detecting an installation of an application-service client on the MAT, the application-service client comprising a client program that communicates with an application server to facilitate access to an application service hosted by the application server, creating a local control interface on the MAT, the local control interface comprising one or more features of an IMS Service Control (ISC) interface, wherein the local control interface facilitates interaction between the local CSCF server and the application-service client; retrieving interoperability information from the application-service client, wherein the interoperability information comprises information of compatibility between the application-service client and the IMS network; determining that the application service is interoperable with the IMS network based on the interoperability information from the application-service client; and interacting, according to a predetermined relationship, with a Serving Call Session Control Function (S-CSCF) associated with the IMS network to facilitate access to the application service, wherein the predetermined relationship is determined in advance based on a specification of the MAT that defines the one or more features of the S-CSCF executable on the MAT. - View Dependent Claims (15, 16, 17, 18, 19, 20)
