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.

21. 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 system;
c) a GPRS mobility management protocol layer (GMM) for managing mobile station mobility;
d) a logical link control protocol layer (LLC);
e) an access mode switch for switching between the unlicensed wireless mode and the GPRS mode;
f) an unlicensed network radio link control entity (RLC); and
g) a GPRS radio link control entity (GPRS-RLC);
i. wherein the GPRS-RLC and the unlicensed network RLC coordinate with each other; and
ii. wherein the unlicensed network RLC and the GPRS-RLC each communicate with the GMM through a GPRS mobility management radio resource management service access point (GMMRR-SAP) interface; and
iii. wherein the unlicensed network RLC and the GPRS-RLC each communicate with the LLC through a GPRS radio resource management service access point (GRR-SAP) interface. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
