Embodiment Construction

[0042] Please refer to the standard document "3GPP TS 25.433 v5.13.0" of the 3GPP standardization organization and the standard document TC5-WG9-2005-065Q-multi-carrier HSDPA Iub interface revision of the China Communications Standards Association for the relevant description of the related messages and tables mentioned below. .

[0043] The present invention realizes effective management of HSDPA resources by supporting the partial success of the physical shared channel reconfiguration request.

[0044] According to the HSDPA resource management method provided by the present invention, as shown in Figure 2, the RNC sends a physical shared channel reconfiguration request to the NodeB, and the Node B responds to the request and configures the HSDPA resources according to the configuration supported by the Node B.

[0045] If the Node B supports part of the configuration in the channel reconfiguration request, it creates / reconfigures / deletes HSDPA resources for the supported part o...

Abstract

The method includes steps: in procedure for configuring or reconfiguring HSDPA resource in sector, in message of configuration request, response, and failure between Node B and RNC, indicating carrier wave info to allot HSDPA resources for configuration supported by Node B first, and to refuse other configurations not supported; thus, the method supports partial successful to configure or reconfigure HSDPA resources of sector to improve efficiency of procedure for configuring resources; when capability of sector or state of resources operation change, making Node B report state of resources operation of HS-DSCH to RNC according to carrier wave; when carrying out common measurement related to HSDPA, common measurement type IE and frequency point info UARFCN IE are cooperated to make measurement related to HSDPA possible to be based on each carrier wave within sector. The invention manages HSDPA resources effectively in order to raise efficiency for running system.

Description

Technical field [0001] The invention relates to the technical field of broadband wireless data communication, in particular to a method for managing high-speed downlink packet access (HSDPA) resources. Background technique [0002] High Speed ​​Downlink Packet Access (HSDPA) is a technology that improves the downlink data transmission rate of the Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) system. It is the 3GPP standardization organization in order to meet the asymmetric requirements of uplink and downlink data services through R5 The (Release 5) version of the system standard proposed that the user downlink service data rate can be increased to above 2.8 Mbps under the existing TD-SCDMA system network structure. [0003] Figure 1 is a schematic diagram of the cell structure of the WCDMA or TD-SCDMA system. As shown in Figure 1, the TD-SCDMA system includes a Radio Network Controller (RNC), Node B (Node B), and User Equipment (UE). The resources related to...
