Abstract
Methods for marking and verifying an authentication status of a wireless communication device are disclosed. When a wireless communication device is authenticated in a first wireless communication network, copies of a token, are stored in memory accessible by the wireless communication device and in memory accessible by a clearinghouse server. The clearinghouse server also stores a correlation between the token and the identity of the server that authenticated the wireless communication device. When the wireless communication device moves from the first network to a second network, the WCD transmits the token to a server in the second network, which can then query the clearinghouse server to determine the identity of the server that authenticated the WCD in the first network, confirm the authentication status of the wireless communication device, and allow the WCD to access a resource in or via the second network.
