Embodiment 3

[0148]In embodiment 3 of the device of the present invention, such as Figure 10 As shown, the device includes an original package multi-version adaptation unit, the original package multi-version adaptation unit:

[0149] An original packet analysis module, configured to analyze the Profile type of the received original packet;

[0150] The compression interface calling module is used to call the version interface corresponding to the Profile type to compress the original package.

[0151] Further, the Profile type selection module selects the Profile type according to the Protocol / Next Header field in the original packet.

[0152] The aforementioned device embodiment 3 can be placed at the compressor end to realize the version adaptation of the original package. It can be understood that, preferably, all the functional modules in the above device embodiments 1 and 3, or all the functional modules in the device embodiments 2 and 3 can be placed in a device capable of realiz...

Abstract

A robust header compression version adaptation method and apparatus and a robust header compression device. The device includes: a uniform external interface which is configured to receive a data packet to be processed, the data packet including a compression packet or including a compression packet and an original packet; and a robust header compression version adaptation apparatus and at least two version interfaces which are configured to process the received data packet according to a version protocol. The solution can realize the use of a plurality of robust header compression versions simultaneously.

Description

technical field [0001] The invention relates to a robust header compression algorithm in the field of mobile communication, in particular to a robust header compression version adaptation method and device. Background technique [0002] Due to the limitation of physical conditions, the wireless link in the mobile communication system has a lower transmission rate and a higher bit error rate than the wired link. In order to effectively utilize limited wireless channel bandwidth resources, a robust header compression technology (RObust Header Compress, hereinafter referred to as ROHC) is introduced. The core of ROHC is to transparently compress and decompress the information in the packet header between directly connected nodes by using the information redundancy between the packets of the service flow. [0003] The ROHC technology currently has two versions, ROHCv1 and ROHCv2, which are respectively described by the RFC3095 document and the RFC5225 document of the IETF (Inte...
