A system and method for mapping packet data functional entities to elements in a communication network is disclosed. The system allows the PPP/HDLC protocol to terminate in the packet data serving node (PDSN) element, and isolates the radio access network (RAN) element, which performs functions associated with the radio network, from the PDSN which performs functions associated with the data network. The system also includes a common link layer for coupling the RAN and the PDSN and provides communication through a common link layer identifier on a per wireless communication device basis.
