Embodiment Construction

[0026] The basic principle of the present invention is as image 3 Shown:

[0027] In step s301, the mobile user detects a CPICH (Common Pilot Channel, Common Pilot Channel) received signal of an adjacent cell.

[0028] Step s302, the mobile user sends the measurement result to the wireless management system on the network side. The wireless management system is RNC (Radio network controller, radio network controller) in the WCDMA system; in GSM (Global System for Mobile communications) In the system, it is BSC (Base Station Controller, base station controller); the measurement result includes the size of the CPICH received signal of the adjacent cell, wherein the adjacent cell includes an active set cell and an inactive set cell.

[0029] Step s303, the wireless management system compares the signal quality of each neighboring cell according to the measurement result reported by the mobile user, and judges whether the signal quality of the neighboring cell is better than the...

Abstract

The method includes following steps: a) the mobile user detects the signal quality in neighboring cells; b) the mobile user reports the signal quality in neighboring cells to the wireless management system; c) the wireless management system decides if the signal quality in neighboring cell is better than the one in current serving HS-PDSCH cell; if yes, enters d; otherwise, enters a; d) HS-PDSCH cell is switched to a neighboring cell with better signal quality. By using the invention, user can be kept in a serving cell with better signal quality.

Description

technical field [0001] The invention relates to the switching of serving cells of the high-speed physical downlink shared channel in a wireless communication system, in particular to a method for dynamically switching the serving cells of the high-speed physical downlink shared channel. Background technique [0002] HSDPA (High Speed ​​Downlink Packet Access) is a solution for WCDMA (Wide-band Code Devision Multiple Access) downlink high-speed data access, which can effectively solve the problem of limited downlink capacity. In the prior art, when a mobile user supporting HSDPA technology requests to use HSDPA to transmit non-real-time data services, the wireless management system maintains a DPCH (Dedicated Physical Channel, Dedicated Physical Channel) from the active set cell where the mobile user is located (and the mobile user ) selects a cell with the best signal quality among all cells connected by ) channels, and establishes a HS-PDSCH (High Speed ​​Physical Downlink ...
