Embodiment Construction

[0085] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0086] In the prior art, the use of the IP protocol header compression mechanism can solve the problems of high overhead of the IP header on the default bearer, wasting bandwidth, increasing the probability of message discarding, and reducing QoS, while ensuring the inherent flexibility of the IP protocol. In a wireless cellular network LTE (Long Term Evolution, long-term evolution) system, ROHC (Robust Header Compression, robust header compression) is used to perform header compression on IP voice packets.

[0087]ROHC is a stream-based header compression scheme. During network data transmission, most header fields in packets of the same flow have the same field value. The ROHC mechanism takes a reference packet in a certain flow, and only sends the ch...

Abstract

The invention provides an IP (Internet Protocol) header compression method and apparatus, user equipment and a base station, relates to the field of communication, and solves the problem the conventional IP header compression mechanism cannot solve a problem of large header expense on a default bearer. The method comprises steps of determining whether to carry out IP header compression of an IP message of currently-operating data traffic according to service features of the currently-operating data traffic; sending an IP header compression activation request to a base station when carrying out IP header compression of the IP message of the currently-operating data traffic; receiving an IP header compression activation command returned by the base station; compressing an IP message meeting IP header compression starting conditions and sending the compressed IP message to the base station according to the IP header compression activation command; or decompressing the IP message subjected to IP header compression received by the base station and sending the decompressed IP message to a non-access layer of user equipment The scheme of the invention is suitable for IP messages on the default bearer, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a method, device, user equipment and base station for IP protocol header compression. Background technique [0002] Protocols such as VoIP (Voice over Internet Protocol, Internet telephony), IP (Internet Protocol, Internet Protocol), UDP (User Datagram Protocol, User Datagram Protocol) or RTP (Real-time Transport Protocol, real-time transport protocol ) of ordinary voice data transmitted, the IP header may represent about 70% of the packets, which leads to very inefficient use of the link. For example, for an IPv6 (Internet Protocol Version 6, Internet Protocol Version 6) voice message, the payload of the message actually needed by the user may only account for 22% of the entire packet, and the other part is occupied by the IP header. This not only wastes bandwidth, but also increases the probability of packet packets being discarded due to packet packet errors. If effective measures ...
