A method for allowing a mobile of a wireless communication simultaneous access to multiple data networks coupled to the wireless communication network. A network interface is created between network controlling elements, such as Base Station Controllers, of the wireless communication network. The network interface allows various communication channels established by the mobile to be routed to network controlling elements that are coupled to the various data networks. Information from various established communication channels are routed between various network controlling elements. Thus, a mobile is able to communicate simultaneously with different data networks. The network interface also allows handoffs to be executed with virtually no interruptions and no loss of information being exchanged between the mobile and system equipment involved in the handoff.
