ABSTRACT:
A wireless network gateway for transmitting data between a wireless network and a packet data network. The wireless network gateway comprises: 1) N input-output processors for transmitting and receiving data packets to and from the wireless network and the packet data network; 2) M service processors for performing packet data serving node (PDSN) functions associated with data sessions between the packet data network and mobile stations communicating with the wireless network; 3) a switch fabric for the N input-output processors and the M service processors; and 4) P switch modules. Each of the P switch modules transfers data packets between the switch fabric and at least one input-output processors. A first switch module stores session bindings information associated with a first data session between a first mobile station and the packet data network.
