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.
