Abstract: A method and system enables communications between a switched telephone network and a wireless network comprising a plurality of Mobile Switching Centers (MSCs). Each MSC is connected by respective interfaces to a broadband packet network used for the transfer of bearer traffic between the MSCs, and controls wireless communications with a respective plurality of wireless transceivers. The switched telephone network and the wireless network are interconnected by at least one media gateway for conveying bearer traffic between the switched telephone network and the broadband packet network. The system comprises a location register and a call manager. The location register is adapted to store, in respect of each wireless transceiver, information identifying a respective current MSC controlling communications with the wireless transceiver. The, call manager is adapted to: query the location register to obtain the information identifying the current MSC respecting the selected wireless transceiver; and enable a communications path across the broadband packet network between an inbound media gateway and the current MSC. The advantages include simplified routing, congestion reduction and reduced cost of infrastructure to support a rapidly expanding wireless subscriber base.

Abstract: An Interworking Gateway enabled to provide continuous conversion of Protocol Data Units (PDUs) of any one of a provisioned set of transport protocols to any other member of the set is disclosed. Each transport protocol is associated with at least one transport protocol unit comprising at least one signaling port, at least one receive path, and at least one transmit path. Receive paths are adapted to convert PDUs of respective transport protocols into a base format, and transmit paths are adapted to convert a stream of base format data into PDUs of respective transport protocols. Transport protocol units are autonomous modules. The Interworking Gateway permits telephone services to extend across different broadband telephony networks in today's telecommunications system of networks.
