A Wireless Mobility Gateway (MOGW) creates a wireless connection to allow a mobile terminal to perform IP packet transmission and reception and make use of mobile data services. The MOGW is able to directly route packets to the Internet and Corporate Networks, thus rendering the whole mobile network more efficient and simpler to construct and manage. The MOGW generates a special tunnel identifier to identify the wireless connection that must be contained in all packets received from the RAN. The MOGW generates such a tunnel identifier by concatenating a number of values that characterize the connection. Therefore, simply by reading this tunnel identifier, the MOGW can more efficiently forward packets appropriately. The Mobility protocol and function between MOGWs allows Mobile terminals to easily move between geographical areas served by different MOGWs.
