Problems solved by technology

[0023] First of all, since the radio resource management protocol stack is moved down to the iNodeB, the switching between iNodeBs will be very frequent. When the UE switches between iNodeBs, there will be a large number of contexts related to header compression and encryption that need to be migrated on the Iur interface. This may lead to traffic congestion on the Iur interface, and the resources of this interface are very precious
[0024] Secondly, the data on the Iu_u interface cannot be compressed and encrypted, and the data security and bandwidth usage efficiency of this interface will be seriously affected

Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0072] The structure of a mobile communication network in a preferred embodiment of the present invention is shown in FIG. 7 .

[0073] In the mobile communication network, the communicating network element nodes include a base station, an IP access gateway, IN UPS and IN CPS. The IN UPS is responsible for the convergence and centralized processing of user plane data transmission, and the IN CPS is responsible for the control plane function of the RAN Server intermediate node. That is to say, the IN UPS and the IN CPS belong to the same layer of nodes.

[0074] The connection between entities in the mobile communication network will be described below.

[0075]The IP access gateway is connected to the IN CPS and IN UPS respectively, the interface between the IP a...

Abstract

The invention is used for solving the issue of traffic congestion brought by compression and encryption at iNodeB in evolving network architecture. In the invention, the 'IN' of RAN server of currently-used evolving network is expanded into 'IN CPS' and 'IN UPS', the 'IN CPS' is used in implementing the convergence and centralized process functions for user plane data transmission, including user plane header compression and encryption; the 'IN UPS' has same function of RAN server control plane.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a mobile communication network and a data transmission method thereof. Background technique [0002] Universal Mobile Telecommunications System (UMTS for short) is a third-generation mobile communication system that adopts Wideband Code Division Multiple Access (WCDMA for short) air interface technology. It is called WCDMA communication system. The UMTS system adopts a structure similar to that of the second-generation mobile communication system, as shown in Figure 1, including the Universal Mobile Telecommunications System Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network, referred to as "UTRAN") and the core network (Core Net, referred to as "CN"). Among them, UTRAN is used to handle all wireless-related functions, while CN handles all voice calls and data connections in the UMTS system, and realizes switching and routing functions with external networ...
