Method for selectively maintaining and applying PPP compression in a wireless communication system

DETAILED DESCRIPTION The present invention addresses the need identified above by providing a method that determines when to maintain a compression state and apply compression techniques on a wireless communication device.
Methods consistent with the principles of the present invention as embodied and broadly described herein include a communication device for receiving packetized data transmitted from a terminal device which is coupled to the communication device via an R.
sub.
m interface.
The communication device determines whether the received packetized data comprises compressed or uncompressed headers and then determines whether connection information identifying a compression slot is included in the compressed data in response to determining that the received packetized data comprises compressed data.
The communication device further determines whether the connection information exceeds a highest-numbered decompression slot from a plurality of decompression slots on said U.
sub.
m interface.
The communication device sets up a local decompression slot, in the communication device, which corresponds to the connection information in order to maintain said compression state, wherein the local decompression slot is set up in response to determining that the connection information exceeds the highest numbered decompression slot.
The communication device decompresses the compressed packetized data when it receives compressed packetized data containing said connection information.
