Abstract:
A method for maintaining a compression state and applying a compression technique after a PPP renegotiation on a Um interface of a wireless communication network, said method comprising:receiving, in a communication device, packetized data transmitted from a terminal device, said terminal device coupled to said communication device via an Rm interface; ascertaining whether said received packetized data comprises compressed or uncompressed data; determining, in response to ascertaining that said received packetized data comprises compressed data, whether connection information identifying a compression slot is included in said compressed data and whether said connection information exceeds a highest-numbered decompression slot from a plurality of decompression slots on said Um interface; and decompressing, in response to determining that said connection information is included in said compressed data and that it exceeds said highest-numbered decompression slot, said compressed packetized data in a local decompression slot configured in said communication device, when said communication device receives compressed packetized data containing said connection information.
