Method of providing improved integrated communication system data service
First Claim
1. A method of providing packet switched data services in a communication system comprising a first communication system and a second communication system, the first communication system comprising a licensed radio access network and a core network comprising a Gateway General Packet Radio Service (GPRS) Support Node (GGSN) for interfacing to a packet services network and a Serving GPRS Support Node (SGSN) for interfacing the licensed radio access network to the GGSN, the second communication system comprising a network controller that communicatively couples a user equipment in a service region of the second communication system to the core network of the first communication system, the method comprising:
- establishing a secure tunnel between the network controller and the user equipment;
receiving a data service session request from the user equipment over the secure tunnel;
establishing a GPRS Tunneling Protocol (GTP) tunnel between the network controller and the GGSN, the GTP tunnel bypassing the SGSN, the network controller emulating the SGSN to the GGSN; and
through the GTP tunnel, providing packet switched data services of the packet services network to the user equipment.

Abstract
Some embodiments provide a method and apparatus for seamlessly providing voice and data services across a licensed wireless network while accessing a second different communication network through a user equipment. The first and second communication networks include licensed wireless networks, unlicensed wireless networks, or Internet Protocol (IP) networks, to name a few. Furthermore, some embodiments of the second communication network include a modified interface for directly interfacing with components of the first communication network in order to pass and retrieve data packets from the user equipment.
