Abstract
According to certain embodiments of the present invention, Wireless Mobility Gateway (MOGW) method and apparatus determines whether a wireless connection has been requested by a mobile terminal. As a consequence it performs security functions to authenticate the mobile user and grant access. If requested by the mobile user it then also creates a wireless connection to allow it to perform IP packet transmission and reception and therefore make use of mobile data services. The MOGW is able to directly route packets to 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.
