A method for authenticating a mobile terminal in a wireless network is disclosed. The method includes transmitting a request for authenticating the mobile terminal in that wireless network operative to provide services at a location where the mobile terminal is currently present, receiving the request at a base station associated with that wireless network, and determining an entity associated with the wireless network to be operative as a single authentication access entity for that mobile terminal, as long as the mobile terminal location remains within that wireless network and traffic is directed through any location associated with that wireless network.
