1. A service gateway decomposition method in an Internet Protocol (IP) Multimedia Subsystem (IMS) network, the method comprising:
- effectuating a signaling interface via said IMS network with respect to an email services server using a service gateway controller (SGC);
effectuating a message transport interface with respect to said email services server using at least one of a plurality of service gateways (SGWs); and
interfacing said SGC with said plurality of SGWs using a signaling architecture for controlling a message path for a current messaging session between said email services server and a service client associated therewith, wherein said message path is effectuated via a particular SGW as an end-to-end session between said email services server and said service client in a dynamically configurable routing arrangement, said service client having a signaling flow path to said SGC via said IMS network and a message flow path to said particular SGW, such that said message path can be redirected via another SGW of said plurality of SGWs for said current messaging session.

Abstract
In one embodiment, a service gateway decomposition method is described that is operable in an Internet Protocol (IP) Multimedia Subsystem (IMS) environment. A service gateway controller (SGC) is provided for effectuating a signaling interface with respect to at least one remote services server. One or more service gateways (SGWs) are provided for effectuating a message transport interface with respect to the remote services server, wherein the SGC and SGWs are interfaced together using a suitable signaling architecture.

11. A service gateway controller (SGC) configured to operate in an Internet Protocol (IP) Multimedia Subsystem (IMS) network, said SGC comprising:
-
means for effectuating a signaling interface with respect to an email services server via said IMS network; means for effectuating a signaling interface via said IMS network with respect to a service client executing on a mobile communications device, wherein said service client is associated with said email services server; and means for effectuating a signaling interface with respect to a plurality of service gateways (SGWs) to control a message path for a current messaging session between said email services server and said service client associated therewith, wherein said message path is effectuated via a particular SGW as an end-to-end session between said email services server and said service client in a dynamically configurable routing arrangement, said service client having a signaling flow path to said SGC via said IMS network and a message flow path to said particular SGW, such that said message path can be redirected via another SGW of said plurality of SGWs for said current messaging session. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A non-transitory computer-readable medium having program code thereon for execution by a processor of a network node in association with an Internet Protocol (IP) Multimedia Subsystem (IMS) network, the non-transitory computer-readable medium comprising:
-
instructions for effectuating a signaling interface with respect to an email services server via said IMS network; instructions for effectuating a signaling interface via said IMS network with respect to a service client executing on a mobile communications device, wherein said service client is associated with said email services server; and instructions for effectuating a signaling interface with respect to a plurality of service gateways (SGWs) to control a message path for a current messaging session between said email services server and said service client associated therewith, wherein said message path is effectuated via a particular SGW as an end-to-end session between said email services server and said service client in a dynamically configurable routing arrangement, said service client having a signaling flow path to said SGC via said IMS network and a message flow path to said particular SGW, such that said message path can be redirected via another SGW of said plurality of SGWs for said current messaging session.
