Problems solved by technology

[0008] Secondly, when OMC-B cannot realize remote operation, the simulated loading of each Node B will have to be carried out on the station, which will greatly consume manpower and time
[0009] Third, since the RNC and Node B are configured separately, the consistency of their data is not easy to guarantee
The resource conditions recorded by RNC and Node B will be different, which may affect normal user access and testing

Embodiment Construction

[0019] The features and technical content of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments. The drawings are only used to explain the invention and not to limit it.

[0020] In the present invention, by modifying the wireless link establishment request message in 3GPP protocol 25.433, RNC2 can perform the frequency points, time slots, code channels, power, shaping angles, and each cycle that Node B1 needs to load through NBAP signaling. Configure parameters such as the adjusted step size and initial shaping direction, and record resource occupancy in the RNC for simulated loaded resources to ensure that normal user access is not affected, thereby realizing centralized control of simulated loading of Node B1. And through the normal resource release process, RNC2 reclaims the simulated loaded resources.

[0021] Such as figure 2 Shown is the flow chart of the simulated loading scheme of the presen...

Abstract

The invention discloses a Node B simulation loading method under RNC centralized control, comprising: a simulation loading data file making step; a simulation loading step; a simulation loading recovery step, wherein the simulation loading data file making step is that, the simulation loading wireless link building request information is made on RNC, including parameters required by loading and simulation loading indication. According to the invention, through modifying wireless link building information, RNC performs configuration of simulation loading parameters on the Node B through NBAP signalling, thereby realizing the centralized control of simulation loading on the Node B. For the simulation loading resource, the resource occupying record is performed in RNC, to ensure not to affect the normal user access. Through normal resource release process, RNC recovers simulation loading resource.

Description

technical field [0001] It relates to the field of mobile communication, in particular to a Node B simulation loading method under the centralized control of RNC. Background technique [0002] According to the basic standards of the IMT-2000 system, the third-generation mobile communication system is mainly composed of four functional subsystems, which are core network (CN), radio access network (RAN), mobile station (MT) and subscriber identity module ( UIM), wherein the radio access network part can be further divided into two parts: Node B (Node B, logically corresponding to a GSM base station) and a base station controller (RNC). [0003] The main function of Node B is to perform wireless interface layer processing, such as channel coding and interweaving, rate matching, spread spectrum, etc., and it usually spreads all over the network coverage area, such as urban areas, suburban counties, rural areas, and mountainous areas. The main function of the RNC is to control th...
