AI Technical Summary

Problems solved by technology

When the terminal moves to the cell boundary, the terminal will not be able to use multiple carriers for data transmission because the cell with fewer carriers has not been deleted from the active set, so the data transmission rate cannot reach the peak value, and the transmission effect is not good

Embodiment 1

[0024] Please refer to figure 1 , is a flow chart of a method according to an embodiment of the present invention, and may include the following steps:

[0025] Step 101: Detect the forward wireless environment where the terminal is located;

[0026] Step 102: When the forward radio environment satisfies the update condition, update the carrier assignment to the terminal.

[0027] It can be seen that the detection of the forward wireless environment can determine the number of carriers allocated to the terminal. Therefore, when the terminal moves to the cell boundary and the forward wireless environment meets the update conditions, the number of carriers allocated to the terminal can be updated to enable data transmission. to achieve the best transmission status.

[0028] figure 1 The steps shown can be applied to the scenario of handover in the HRPD system. Wherein, the forward wireless environment mentioned in step 101 may include: forward pilot strength or DRC Cover (Da...

Abstract

The embodiment of the invention discloses a method, a device and a system for distributing carrier wave. The method is used for terminal to switch cell, and includes steps of detecting the forward wireless environment of the terminal; and updating the carrier wave distribution of the terminal when the forward wireless environment satisfies the updating condition. In the scene of carrying out switching, when the terminal moves to cell boundary, the invention can make the data transmission to optimum state.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method, device and system for allocating carriers. Background technique [0002] After CDMA (Code Division Multiple Access, Code Division Multiple Access) technology evolved to HRPD (High Rate Packet Data, high-speed data packet service) Rev.B, multi-carrier bundling technology was introduced. By assigning multiple carriers to the terminal, the data transmission rate can be increased, so that the forward peak rate can reach 14.7Mbps, and the reverse peak rate can reach 5.4Mbps. [0003] During the research process, the inventor found that in the scenario of handover in the HRPD system, when the terminal moves to the border of the cell, since the number of carriers configured in each cell in the active set of soft handover is different, the number of carriers finally allocated to the terminal can only be The minimum number of carriers in each cell, therefore, m...
