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.
