Abstract
Apparatus and method are disclosed that enable an organization's enterprise-wide network to accommodate roaming wireless terminals that are affiliated with the local enterprise networks within the enterprise-wide network. An embodiment of a system is capable of handling a wireless terminal, such as a cellular telephone, that is able to use different SIM cards in different geographic regions or service-provider networks. A mobility client that is part of the wireless terminal registers when it detects that a new SIM card has been installed at the wireless terminal, whereby the client provides the subscriber-specific information that the wireless terminal reads from the SIM card. The mobility client identifies itself to the server by a user identifier, such as the station extension with which the terminal is affiliated back at the home local enterprise network. Upon successful registration, the client receives an access number suitable for its current location.
