A wireless communication system for mobile devices including an air interface and a packet network. A modified mobile IP interface is utilized to provide a communication protocol for the wireless air interface. The wireless communication protocol is interfaced to a Generic Routing Encapsulation data tunneling protocol to transport communications through a packet switched data communication network. The Generic Routing Encapsulation header encapsulates the communication and control information and also accepts a network address as a session ID values to identify different communication sessions.
