Problems solved by technology

With the continuous development and change of wireless access network requirements, the interference scenarios between cells are becoming more and more complex. If the cell management is not good, it will cause serious interference between cells or cracks in cell coverage.
[0003] The inventor found through research that, in the case of a large number of cells, the cells configure the uplink and downlink ratios according to their own uplink and downlink business requirements, so that different cells will configure different uplink and downlink ratios, which will cause inter-cell Serious uplink and downlink interference, if such interference is avoided by reducing the transmit power of the cell site, it will bring coverage gaps between cells

Embodiment 1

[0029] A method for cell management provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0030] 101. Group the cells to obtain a target group list;

[0031] 102. Receive the uplink and downlink ratios sent by the cells in the target group list;

[0032] 103. Determine a target uplink and downlink ratio according to the uplink and downlink ratios of each cell in the target group list, and the target uplink and downlink ratio is used to provide each cell in the target group list for uplink and downlink service transmission .

[0033] According to a cell management method provided by an embodiment of the present invention, a target group list is obtained by grouping cells, and the target uplink and downlink ratio is determined by receiving the uplink and downlink ratios sent by the cells in the target group list. The target uplink-downlink ratio is used to provide each cell in the target group list for uplink-downlink service tr...

Embodiment 2

[0040] An embodiment of the present invention provides a method for cell management, such as image 3 As shown, CCE (Central Control Equipment, centralized management equipment) performs centralized management on the base stations of multiple cells, and the interface between the CCE and the base station is any one of air interface, S1 interface, Ethernet interface or optical interface, such as Figure 4 As shown, the specific steps of the method are as follows:

[0041] The cells are grouped by the CCEs, and a target group list is obtained.

[0042] 201. The CCE selects a cell from a reference cell list as a reference cell, and the reference cell list includes cells managed by the CCE.

[0043] For example, the cells managed by the CCE include cell 1, cell 2, cell 3, cell 4, and cell 5, and cell 1 is selected as a reference cell.

[0044] 202. The CCE receives an interfering cell list sent by the base station of the reference cell, where the interfering cell list includes ce...

Abstract

The invention discloses a method and device for managing cells, and relates to the technical field of communication. The problem that interference between uplinks and downlinks among cells is severe because uplink and downlink ratio of different cells is configured according to respective service requirements of the different cells is solved. According to the technical scheme, the method includes the steps of grouping the cells, obtaining a target grouping list, receiving uplink and downlink ratio sent by the cells in the target grouping list and determining a target uplink and downlink ratio according to the uplink and downlink ratio of the cells in the target grouping list, wherein the target uplink and downlink ratio is used for being supplied to each cell in the target grouping list for conducting uplink and downlink service transmission. The method and device are suitable for the process of cell management.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell management method and device. Background technique [0002] The Long Term Evolution (LTE) system supports Time Division Duplexing (TDD, Time DivisionDuplexing), that is, uplink (UL, Uplink) and downlink (DL, Downlink) use different time slots of the same frequency. The LTE TDD system can dynamically or semi-statically configure the cell uplink and downlink ratio according to different service types to meet different uplink and downlink asymmetric service requirements. With the continuous development and change of wireless access network requirements, the interference scenarios between cells are becoming more and more complex. If the cell management is not good, it will cause serious interference between cells or cracks in cell coverage. [0003] The inventor found through research that, in the case of a large number of cells, the cells configure the uplink ...
