Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further elaborated below in conjunction with the accompanying drawings.

[0034] The existing problem of the processing method when the ROHC-U mode makes mistakes in the prior art is that there is no feedback channel from the decompression side to the compression side. Therefore, the core content of the present invention is to increase the feedback channel from the decompression side to the compression side: When the decompressor makes an error, it will send an error message to the compressor through the newly added feedback channel; the compressor will immediately send an IR packet or IR-DYN packet to the decompressor after receiving the error message, so that the context of the decompressor can be updated in time , so that the decompression side can quickly return to normal working status.

[0035] The following will take the Broadcast and Mu...

Abstract

This invention discloses one robust head compression U mode error process method, which comprises the following steps: a, decompress or transfers the top and down FC status with completeness into lower status and sends status transfer indication information; b, compressor receivers the transfer indication information and sends the needed message to decompress or part; c, decompress or part transfers the message to FC status according to the received message.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for processing errors in robust header compression U mode. Background technique [0002] Robust Header Compression (Robust Header Compression, ROHC) is a header compression scheme proposed by the Internet Engineering Task Force (IETF) in the standard document RFC3095, which currently defines four header compression frameworks, They are Real-time Transport Protocol (Rea1-time Transport Protocol, RTP) / User Datagram Protocol (User Datagram Protocol, UDP) / IP, UDP / IP, Encapsulation Security Payload (Encapsulation Security Payload, ESP) / IP and Uncompressed (Uncompressed) , which details a very efficient and robust header compression method for the first three types of packets. [0003] In ROHC-U mode, when the functional entity performing compression (referred to as the compressor) has continuously sent the number of packets reaching a preset value, it will tra...
