Patent ID: 7606238

Claim:
A packet communication method comprising the steps of: establishing a single radio layer 2 connection based on a radio layer 2 protocol, between a mobile station and a controller device, the single radio layer 2 connection associated with multiple GTP (GPRS Tunneling Protocol) based connections; receiving, at the controller device, data packets in which respective qualities of service are set; inputting, at the controller device, the data packets to queues corresponding to the respective qualities of service; determining, at the controller device, a timing for taking out each data packet of the data packets from the queues corresponding to the respective qualities of service, based on the respective qualities of service; and multiplexing, at the controller device, each data packet of the data packets taken from the queues at the determined timing into a radio layer 2 protocol data unit of a fixed length which is transmitted and received on the single radio layer 2 connection associated with multiple GTP based connections.
