Method for compressing communication message head

Abstract

This invention relates to message initial compression method, which comprises the following steps: defining wireless interface user interface agreement shed; processing compression process between agreement shed internet and core internet mouth. This invention can process effective compression between internet and core interface.

Description

technical field [0001] The invention relates to the field, in particular to a method for performing header compression on communication messages. Background technique [0002] UMTS (Universal Mobile Telecommunications System; Universal Mobile Communication System) is a third-generation mobile communication system that adopts WCDMA (Wideband Code Division Multiple Access; Wideband Code Division Multiple Access) air interface technology. The UMTS system is usually also called WCDMA communication system. [0003] The UMTS system adopts a structure similar to that of the second generation mobile communication system, as shown in Figure 1, including a radio access network (Radio Access Network, RAN), such as UTRAN (UMTS Territorial Radio Access Network UMTS; terrestrial radio access network), Core network (Core Network, CN), external network and user equipment (User Equipment, UE). [0004] Among them, the wireless access network is used to handle all wireless-related functions...

Problems solved by technology

Therefore, the problems of IP transmission delay and transmission efficiency between the access network and the core network have not been resolved.

[0016] In addition, in the existing 3G network, because the RNC implements the header compression function, the data on the Iub interface between the RNC and the NodeB is also compressed objectively, which is helpful for saving the last mile or backhaul (backhaul) transmission resources in operation It is very important in terms of investment. In the evolved network, since most of the functions of RNC are moved down to ERS, if the header compression function is also moved down, the transmission resources between IAGW and ERS still have the characteristics of the previous last mile , if there is no compression on this link, then the network construction cost of the operator will be very high, because the last mile link is very large, if there is a large bandwidth demand, the investment will inevitably increase

[0017] Moreover, in the future network evolution architecture, the CS domain will disappear, only the PS domain will exist, and the voice will be carried by the PS domain in the form of VOIP, which means that there will be a large number of VOIP services between the access network and the core network in the future. RTP packets, and we know that the header bytes in RTP packets often account for more than 80%, so this will greatly waste the bandwidth, transmission efficiency and delay of backhaul, so it is necessary to reconsider a set of headers in the new network architecture A Complete Solution for Compression
