Abstract
An overlay to an existing cellular switching structure to provide post-second generation services without the need to make modifications or updates to the existing infrastructure is disclosed. The overlay preserves second generation switching while providing post-second generation services. The overlay includes a post-second generation infrastructure for providing processing of post-second generation communication services, a first interface, coupled to the post-second generation infrastructure, for providing an access interface to a base station subsystem and processing base station subsystem signaling based upon a type of service and a type of call flow associated with the received signaling from the base station subsystem, and a second interface, coupled to the post-second generation infrastructure, for providing an inter-system interface to a signaling network and processing inter-system signaling between the signaling network, the first interface, the existing switching infrastructure and the post-second generation infrastructure. The first interface comprises an access interface manager, the access interface manager outputting access interface signaling based on base station …
