METHOD FOR FACILITATING ACCESS TO A FIRST ACCESS NEWORK OF A WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION DEVICE, AND WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method for facilitating access to a first access network of a wireless communication system, the method comprising:
- authenticating a wireless communication device with a second access network and generating temporary access credentials using access information provided by the second access network;
transforming by the wireless communication device the temporary access credentials and an identifier of the first access network to provide first transformed access credentials; and
transmitting the first transformed access credentials for performing authentication with the first access network;
providing the identifier of the first access network to the second access network and generating by the second access network second transformed access credentials using the identifier of the first access network and the temporary access credentials; and
performing authentication with the first access network, including comparing the first transformed access credentials with the second transformed access credentials and allowing access to the first access network when the first transformed access credentials and the second transformed access credentials are substantially the same.

Abstract
A method for facilitating access to a first access network (110) of a wireless communication system (100) comprises authenticating (300) a wireless communication device (102) with a second access network (104) and generating temporary access credentials using access information provided by the second access network (104). The wireless communication device (102) then transforms (302) the temporary access credentials and an identifier of the first access network (110) to provide first transformed access credentials which are transmitted (304) for performing authentication with the first access network (110). The identifier of the first access network (110) is provided to the second access network (104) which generates (308) second transformed access credentials using the identifier of the first access network (110) and the temporary access credentials. Authentication is performed (310) with the first access network (110), which includes comparing the first transformed access credentials with the second transformed access credentials and allowing access to the first access network (110) when the first transformed access credentials and the second transformed access credentials are substantially the same. A wireless communication device, and a wireless communication system are also disclosed and claimed.
