CELLPAC: A packet radio protocol applied to the cellular GSM mobile radio network

The CELLPAC (cellular packet radio) protocol is introduced, and its traffic performance is evaluated. The protocol is based on reservation of slots out of a GSM (Groupe Special Mobile) cellular radio network traffic channel, assigned to the respective service, and supports multipacket message communication between mobiles of a GSM cell. Contrary to the usual way of operation, a base station repeats packets received on the uplink of the CELLPAC channel on the respective downlink, whereby a local-area buslike communication network is established. The protocol has been formally specified in Estelle and applied in a simulated mobile environment.<
