Problems solved by technology

[0004] The existing DC-HSDPA technology has at least the following disadvantages: the uplink signaling transmission indication message received by the SRNC only includes the main carrier information of the DC cell (Dual-Cell, dual-cell), so the SRNC cannot update the cell in the UE During the process, apply DC-HSDPA to send data for UE

Abstract

The embodiment of the invention discloses an implementation method, device and system of a multi-carrier high speed downlink packet access technique. The method is applied to the cell updating process carried out by user equipment (UE) and comprises the following steps of: receiving an uplink signaling transmission indication message, wherein the uplink signaling transmission indication message comprises the cell information of a cell updated by the UE and the auxiliary carrier cell information of the cell updated by the UE; sending data to the UE on the cell updated by the UE and an auxiliary carrier cell thereof by applying the multi-carrier DC-HSDPA (Direct Current-High Speed Downlink Packet Access technique according to the cell information of the cell updated by the UE and the auxiliary carrier cell information. Through the embodiment of the invention, an SRNC (Serving Radio Network Controller) can send the data to the UE by applying the DC-HSDPA in the process of UE updating thecell.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and system for realizing multi-carrier high-speed downlink packet access technology. Background technique [0002] In order to improve the throughput of UE (User Equipment, user equipment) by improving the performance of HSPA+ (High Speed ​​Packet Access, high-speed packet access) technology, 3GPP (3rd Generation Partnership Project) proposed DC- HSDPA (DC-High Speed ​​Downlink Packet Access, multi-carrier high-speed downlink packet access technology) technology. [0003] The DC-HSDPA technology allows the UE to simultaneously receive HSDPA (High Speed ​​Downlink Packet Access, High Speed ​​Downlink Packet Access) data sent by two cells with different frequencies and the same coverage. The SRNC (Serving Radio Network Controller, Serving Radio Network Controller) can dynamically select two mutually primary and secondary carriers, and schedule HSDPA...
