Abstract:
The present invention concerns a method for optimizing ROHC RTP (Robust Header Compression Real Time Protocol) compression applied to IP header of data packets stream so as to use more compact formats enable to remain in a steady state, to never discard received packet, and to serve radio resources without requiring to modify ROHC specification. In the method, when handover or mobility procedure is started, new reference values are normally added to a sliding compression window, but no reference value is removed from the window as long as the handover or mobility procedure is on going. After the handover or mobility procedure is complete, when the number of values transmitted on the new radio link are appropriate to cope against the error properties on the new link, all older values can be removed at once from the compression window, thereby reverting to normal window operation.

Claim (Index 4):
A mobile terminal which communicates with a communication apparatus comprising a header decompressor, the mobile terminal comprising:\n a header compressor; a transceiver; a memory storing instructions; and one or more processors configured to execute the instructions to:\n operate the header compressor in optimistic \u2018O\u2019 mode; \n control the transceiver to receive, when the header compressor of the mobile terminal is operating in the \u2018O\u2019 mode, an indication about Serving Radio Network Subsystem (SRNS) relocation being performed; \n upon reception of the indication about SRNS relocation being performed, for Window-based Least Significant Bit (W-LSB) encoding, update a set of candidate reference values used by the decompressor by adding newly transmitted reference values but not removing old reference values; and \n control the header compressor and the transceiver to compress and transmit, based on the updated set of candidate reference values, until SRNS relocation is completed, Robust Header Compression (ROHC) uplink packets to the communication apparatus.
