Method and apparatus for providing overlay to support third generation cellular services
First Claim
1. An overlay system provided over a first infrastructure in a communications system, comprising:
- an access network, a terminal connected to the access network, a first infrastructure for providing processing of first set of communication services;
a second infrastructure for providing-processing of second set of communication services;
a first interface manager, coupled to the first infrastructure and the second infrastructure, for providing an access interface to an access system and routing access system signaling based upon a type of service associated with the received signaling from an access network subsystem either to the first or the second infrastructure; and
a second interface manager, coupled to the first infrastructure and the second infrastructure, for providing an inter-system interface to a signaling network and processing inter-system signaling between the signaling network and the first and second infrastructures.

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 subsystem signaling received from the base station subsystem according to a type of service and a type of call flow associated with the received base station subsystem signaling. The access interface manager further comprises a base station subsystem manager and a protocol interworking manager and the second interface includes an inter-system interface manager. The post-second generation infrastructure includes a general packet radio service system including a packet handoff manager, a serving general packet radio service support node, and a gateway general packet radio service support node.
