Mobile station GPRS implementation for switching between licensed and unlicensed wireless systems
First Claim
1. A mobile station for accessing both an unlicensed wireless communication system and a licensed wireless communication system, wherein the licensed system is a General Packet Radio Service (GPRS), the mobile station comprising:
- a) a GPRS mode for accessing the GPRS;
b) an unlicensed wireless mode for accessing the unlicensed wireless communication system;
c) a GPRS mobility management (GMM) protocol layer for managing mobile station mobility;
d) a logical link control (LLC) protocol layer;
e) an access mode switch for switching between the unlicensed wireless mode and the GPRS mode;
f) an unlicensed network radio link control (RLC) entity; and
g) a GPRS radio link control (GPRS-RLC) entity;
i. wherein the GPRS-RLC entity and the unlicensed network RLC entity coordinate with each other; and
ii. wherein the unlicensed network RLC entity and the GPRS-RLC entity each communicate with the GMM protocol layer through a GPRS mobility management radio resource management service access point (GMMRR-SAP) interface; and
iii. wherein the unlicensed network RLC entity and the GPRS-RLC entity each communicate with the LLC protocol layer through a GPRS radio resource management service access point (GRR-SAP) interface.

Abstract
An unlicensed wireless service is adapted to generate the interface protocols of a licensed wireless service to provide transparent transition of communication sessions between a licensed wireless service and an unlicensed wireless service. In one embodiment, a mobile station includes level 1, level 2, and level 3 protocols for licensed wireless service and an unlicensed wireless service. An indoor base station and indoor network controller provide protocol conversion for the unlicensed wireless service into a standard base station controller interface of the licensed wireless service.
