Title: Arrangement for data exchange in a wireless communication system
Inventor: DAVIES STEPHEN WILLIAM
IPC: H04L12/56
Filed: 2001-02-08
Abstract: PURPOSE: An arrangement for data exchange in wireless communication system is provided to no further request for handoffs during the transmission of the frames received in the new layer-3 packet in pedagogical and clarity purposes. CONSTITUTION: A penalties associated with relying on layer-4 to handle packets lost as a result of a handoff can be reduced, in accordance with the principles of the invention, by forwarding, in response to a handoff request from a first base station to a second base station, at least one layer-2 frame of a layer-3 packet that is destined to/from the wireless terminal that has been passed down from layer-3 to layer-2, and so is indicated to have been transmitted at layer-3 even though not all of the layer-2 frames of the layer-3 packet have actually been transmitted. Each of the at least one layer-2 frames may be encapsulated together in a special layer-3 packet that is transferred from the first base to the second base station in the usual manner of inter-base-station communication. Advantageously, packets are not lost at layer-4 due to handoffs. Thus, layer-4 retransmissions are not required, and so delays in the network are reduced. Furthermore, if only the layer-2 frames that were not transmitted over the air to the wireless terminal by the first base station are transferred to the second base station, a savings may be had in use of the air interface.
