Embodiment Construction

[0024] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] The invention is a macro-diversity merging method in a wideband code division multiple access full Internet protocol network. For the specific implementation process, see Figure 4 , The flowchart of the macro-diversity combining method in the wideband code division multiple access full Internet protocol network of the present invention is shown as follows:

[0026] 401) After the user enters the macrodiversity, the MDC records the arrival time t1 of the branch where the user first reaches the radio network controller, and determines that the branch is a macrodiversity combined branch;

[0027] 402) MDC records the current time t, this step to step 411) periodically monitor the delay process of each branch;

[0028] 403) Judge whether the cur...

Abstract

The method sets up maximal allowable time delay TComb of branch for user in WCDMA full IP network to carry out merger of macro diversity. When user to carry out merger of macro diversity, if a time relay of a branch to be merged exceeds TComb, merger functional module of macro diversity will inform wireless resources controller (RRC) to delete the branch. The invention controls quality of data and time delay.

Description

Technical field [0001] The invention relates to a macrodiversity processing method in a wideband code division multiple access (WCDMA) full Internet protocol (IP) network, and specifically to a macrodiversity combining method in a WCDMA full IP network. Background technique [0002] In the 3GPP R5 protocol and subsequent versions of the protocol, the WCDMA network structure will all support IP, that is, the three terrestrial interfaces IU / IUB / IUR can all use IP as the transmission protocol. The advantages of this are: First, the transmission bandwidth of the interface can be improved; Second, it can effectively reduce the cost of network construction. In an all-IP network, the network topology of the radio access network (RAN) is as follows: figure 1 Shown. figure 1 Among them, base stations (NodeB) 1, NodeB2, ..., and NodeBn are connected to a radio network controller (RNC) through an IP network. [0003] In actual networking, due to the diversity of the IP network characteris...
