Embodiment 1

[0046] See figure 1 As shown, the neighbor cell maintenance method provided in this embodiment includes:

[0047]Step 101: Obtain the candidate neighbors of the serving cell, the candidate neighbors include the configured neighbors in the list of configured neighbors of the serving cell and the discovered unknown neighbors of the serving cell, which are referred to herein as pending Configure neighbors;

[0048] Step 102: Count the handover performance of each candidate neighboring cell;

[0049] Step 103: Select M neighbors with good handover performance from the candidate neighbors according to the obtained handover performance as formally configured neighbors of the serving cell; where M is less than or equal to the maximum number of neighbors N supported by the serving cell.

[0050] In the above step 101, specifically, the unknown neighboring cell with low serving capacity can be automatically discovered through UE measurement during the ANR process. After the UE measu...

Embodiment 2

[0067] The neighbor cell maintenance device provided in this embodiment can be implemented on the wireless network control SRNC, please refer to figure 2 As shown, it includes: a neighboring cell acquisition module, a statistics module and a selection module;

[0068] The neighbor cell acquisition module is used to obtain the candidate neighbor cells of the serving cell. The candidate neighbor cells include the configured neighbor cells in the configured neighbor cell list of the serving cell and the discovered unknown neighbor cells of the serving cell. This type of unknown neighbor cells is called here. The area is a neighboring area to be configured;

[0069] The statistical module is used to count the handover performance of each candidate neighboring cell of the serving cell;

Embodiment 3

[0089] In this embodiment, an application scenario in which the sum of the number L of adjacent cells to be configured and the number K of adjacent cells to be configured is greater than the maximum number N of adjacent cells supported by the serving cell is used as an example to describe several situations in this scenario. Further illustrative instructions.

[0090] See Figure 4 As shown, the neighbor cell maintenance process shown in this figure includes:

[0091] Step 401: The serving cell has been configured with L configured neighbor cells, L

[0092] Step 402: Detecting K unknown neighboring cells, obtaining the information of these neighboring cells through UE measurement, and putting them into the list of neighboring cells to be configured as neighboring cells to be configured;

[0093] Step 403: start the statistical period;

[0094] Step 404: within the statistical period, count the handover performance of each candidate neighboring cell, specifically count t...

Abstract

The invention discloses a neighbor cell maintenance method and a neighbor cell maintenance device. The neighbor cell maintenance process comprises the following steps: after acquiring candidate neighbor cells of a service cell (including configured neighbor cells in a configured neighbor cell list of the service cell and discovered unknown neighbor cells of the service cell), making statistical analysis of the switching performance of each neighbor cell; and selecting M neighbor cells of good switching performance as formal configured neighbor cells of the service cell according to the switching performance of each neighbor cell. According to the invention, after unknown neighbor cells are detected, whether or not to add the unknown neighbor cells is not judged immediately based on the current remaining space of the service cell. The switching performance of configured and to-be-configured neighbor cells is acquired first, and then, M neighbor cells of good switching performance are selected as formal configured neighbor cells of the service cell. Previously-configured neighbor cells of poorer performance than the selected M neighbor cells are deleted from the configured neighbor cell list. Thus, the added neighbor cells are neighbor cells of best switching performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a neighboring cell maintenance method and device. Background technique [0002] In order to improve the efficiency of neighbor cell configuration, an ANR (Automatic NeighbourRelation) function is introduced in the LTE system. The LTE system can automatically discover unknown neighbor cells through UE (User Equipment) measurement through the ANR function, and automatically add neighbor cell configurations. However, when the cells in the network are densely deployed or deployed in multiple layers, there will be many neighboring cells around the serving cell, which may exceed the number of neighboring cells that the system can support. For example, the number of neighboring cells that the serving cell can support is N, and the number of cells that are adjacent to the coverage of the serving cell is M. Then when M is greater than N, the system cannot be added to the configuration ...
