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 ne...

Embodiment Construction

[0105] The present invention relates to a method for performing header compression on communication messages, the core of which is: defining the protocol stack of the wireless interface user plane; Compression processing.

[0106] The present invention can use various compression algorithms, including point-to-point and end-to-end algorithms, such as IPHC, ROHC and so on.

[0107] The first embodiment provided by the present invention is realized based on a two-layer node architecture. In the case of a two-layer node architecture, there are only two layers of nodes on the network side, ERS and IAGW. The E-I interface is the interface between ERS and IAGW, using IP transmission. The concrete implementation process of the present invention comprises:

[0108]Step 101, define the wireless interface user plane protocol stack of the present invention based on the user plane protocol stack defined by 3G, as shown in Figure 7:

[0109] The ERS has the physical layer (L1), Lower La...

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...
