Abstract
A foreign wireless communication system is operated in a local communication network as if the foreign wireless communication system were a local wireless communication system. A data communication link is established between the wireless communication system and a service provider in a local wireless communication network. An outgoing request for authentication information is communicated from the wireless communication system to a remote administration system over the data communication link. The authentication information is received over the data communication link from the administration system and is transmitted over a signal link from the wireless communication system to the service provider. A requested wireless communication service is received at the wireless communication system based on authentication of the wireless communication system by the service provider using the authentication information.
