Problems solved by technology

[0008] The purpose of the present invention is to provide a kind of method for managing wireless resources in the high-speed downlink packet access system of multi-carriers, to overcome in the prior art by Iub mouth NBAP message RNC can only obtain the information of whole local sub-district / community relevant HSDPA, and cannot Learn the capabilities of multi-carrier bundling supported by Node B and the shortcomings of the corresponding resource operation status, accurately, reasonably and effectively manage the frequency point resources of the cell, and give full play to the multi-carrier HSDPA capability of the cell and UE

Embodiment Construction

[0037] The core of the present invention is to put the HSDPA carrier resources that can be uniformly scheduled by the Node B into a HSDPA carrier resource pool for a cell supporting multiple carriers, and set an identification number for each carrier resource pool. Simultaneously, relevant NBAP message of Iub mouth is made corresponding modification, adds HSDPA resource pool relevant information in resource status instruction message; Adds described carrier resource pool information in audit response message; The corresponding relationship between its frequency point and the HSDPA carrier resource pool, that is, the HSDPA carrier resource pool to which the specified frequency point (UARFCN) belongs; the carrier resource pool information is added in the public measurement initialization request message. The RNC obtains the relevant information of the HSDPA carrier resource pool in the multi-frequency cell through these messages, and then allocates the carrier required by the DPC...

Abstract

The method includes steps: base station collocates resource pool of carrier wave for each cell of supporting high speed down packet access (HSDPA); reporting information of resource pool of carrier wave possessed by each cell to radio network controller RNC; when user equipment (UE) accesses, based on information of resource pool of carrier wave, and multicarrier capability for HSDPA supported by UE, RNC collocates and manages resource of carrier wave of system. The invention manages frequency resources of cell precisely effectively, gives full play of HSDPA capability of multicarrier in cell and UE so as to raise transmission performance of system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for managing wireless resources in a multi-carrier high-speed downlink packet access system. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) is a new technology introduced by 3GPP (Third Generation Partnership Project) in Release 5. It uses AMC (Adaptive Coding and Modulation) and HARQ (Hybrid Automatic Repeat Request) And other technologies can effectively increase the data transmission rate in the downlink direction of the packet service and improve the frequency band utilization of the system. [0003] In the wireless mobile communication system that adopts HSDPA technology, through the Iub interface (the interface between the base station Node B and the radio network controller RNC) message, the RNC can obtain the HSDPA capability and the relevant resource operation status of the local cell / cell in the Node B. [0004] It is st...
