Problems solved by technology

[0003] Among them, during the access process, when the network side allocates code resources for the UE in the cell, sometimes it finds that the resources in the cell are not enough, then it may directly reject the access of the UE at this time, or go to other cells to try to provide code resources for the UE. The UE allocates code resources, resulting in a lower access success rate and longer access time
Similarly, during the handover, when the network detects that the code resource is allocated to the UE in the neighboring cell, it may sometimes find that the resource of the cell is insufficient, which may cause the handover to fail at this time, or try to handover again in another cell, resulting in The success rate of handover is reduced, and the handover time becomes longer

Embodiment Construction

[0025] In the embodiment of the present invention, the network side notifies the user equipment of the code resource occupancy information of each cell; the user equipment selects the target cell according to the channel quality of each cell and the code resource occupancy information.

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0027] figure 1 It is an exemplary flow chart of the method for cell selection in the embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0028] Step 101, the network side notifies the user equipment of the occupancy information of each cell code resource.

[0029] In this step, during specific implementation, the radio network controller (RNC) on the network side may send a code resource occupancy informat...

Abstract

The invention discloses a cell selection method which comprises the following steps: a network side notifies user equipment of the information of occupied code resources in various cells; and the user equipment selects a target cell according to the channel quality and the information of occupied code resources in each cell. Besides, the invention further discloses a system for cell selection, which comprises network side equipment used for notifying the user equipment of the information of occupied code resources in each cell, and the user equipment used for selecting the target cell according to the channel quality and the information of occupied code resources in each cell. The technical scheme can increase the rate of success in cell access or cell switch.

Description

technical field [0001] The present invention relates to communication technology, in particular to a cell selection method, a system for realizing cell selection, a base station and user equipment. Background technique [0002] In the communication system, when accessing a cell, the UE selects a cell with good channel quality to initiate the access process according to the measured channel quality of the cell; during cell handover, the UE can also select a channel according to the measured channel quality of the cell A cell with good quality initiates the handover process, and then the network side allocates code resources for the UE in the cell. [0003] Among them, during the access process, when the network side allocates code resources for the UE in the cell, sometimes it finds that the resources in the cell are not enough, then it may directly reject the access of the UE at this time, or go to other cells to try to provide code resources for the UE. The UE allocates co...
