A mobile application gateway for connecting devices on a cellular network with individual networks, such as enterprise voice and data networks and/or residential networks. The effects of the present invention are far reaching in terms of transferring effective call control from the cellular network into the control of the individual network such as the enterprise, and enabling new business models for the purchase of cellular service from a public cellular carrier by an enterprise. The invention may consist of a primarily of core network and services components based on the IMS network architecture, and is backward compatible to support legacy systems in place in current telecom and data networks.

A method for processing an incoming call to a called terminal in a telecommunications network, implemented by a TAS server in an IMS network. The method includes: interrogating an SDM entity to determine whether the service profile of the user associated with the called terminal contains IN terminating service information; interrogating an SDM entity to determine whether the routing domain to be used to route the call to the called terminal is a circuit or packet type; if the routing domain is a packet type, determining whether the called terminal is effectively reachable in packet mode, and if applicable, via which type of access network; if the service profile contains IN terminating information, allowing the IN terminating service provided for the user of the called terminal to be distinguished according to the type of access network of the called terminal; and routing the call to the called terminal.

A method of establishing a communication link between a mobile terminal of a wireless network and a subscriber of a network, such as an enterprise network, and/or a residential network.

A system that incorporates teachings of the present disclosure may include, for example, a communication device having a controller to retrieve from an address book a communication identifier for each of a plurality of participants, determine from the address book a conferencing type for each of the plurality of participants, and initiate according to the conference type and the communication identifier of each participant a Voice over Internet Protocol conference call directed to communication devices of the plurality of participants. Other embodiments are disclosed.
