Problems solved by technology

[0008] 1. Manually perform point-by-point analysis on the test data, which is costly and time-consuming. In addition, due to the complexity of the on-site network, it is impossible to accurately determine whether it is a cell that is missing from the adjacent cell.
[0009] 2. Due to the rapid construction speed of the current LTE network, the network structure is becoming more and more complex, and the signal is messy. It is impossible to accurately judge which cells are necessary to add neighboring cells and which are unnecessary to add.

Embodiment 1

[0079] This embodiment provides a method for processing missing adjacent cells, the method including:

[0080] Obtaining step S110: Obtain a first cell identifier of a first cell searchable by the user equipment from a measurement report formed when the user equipment camps on the primary cell; the first cell is a cell other than the primary cell;

[0081] Judging step S120: according to the measurement report, judging whether the first cell is a cell satisfying a preset handover condition;

[0082] Determining step S130: comparing the first cell ID with the pre-configured second cell ID of the neighboring cell, when the first cell ID is not included in the second cell ID and the first cell is When the cell meets the preset handover condition, it is determined that the first cell is a missing neighbor cell of the primary cell.

[0083] Specifically, the user equipment may include a mobile phone, and the mobile phone usually receives the measurement control information sent by...

Embodiment 2

[0117] Such as image 3 As shown, this embodiment provides a method for determining a missing adjacent cell, the method comprising:

[0118] Step S210: Obtain the sampling point data of the main cell by drive test; wherein, the sampling point data includes signal quality parameters of the second cell signal: the second cell signal is a signal sent by the second cell; the second cell signal is a signal sent by the second cell; The second cell is a cell other than the main cell;

[0119] Step S220: Determine whether the second cell is a neighboring cell of the primary cell according to the signal quality parameter of the signal of the second cell; wherein, the neighboring cell is the first neighboring cell;

[0120] Step S230: comparing the cell identity of the first neighboring cell with the cell identity of pre-configured neighboring cells, and determining whether the first neighboring cell is included in the pre-configured neighboring cells;

[0121] Step S240: When the fir...

example 1

[0174] This example analyzes and finds the missing configuration method of LTE neighbor cells based on the playback of existing drive test data. As well as cells with strong continuous signal strength in the sampling points and cells that are closer to the main serving cell, certain screening conditions and scoring sorting are used to find cells that are missing from neighboring cells.

[0175] This example includes two core contents, one is to find missing neighboring cells based on the A3 event in the measurement report; Areas with missing allocation. The A3 event is an event that the quality of service of a neighboring cell is higher than a threshold.

[0176] Step 1: Analyze the A3 event in the signaling, decode the MR (Measurement Report, MR) report of the A3 event, obtain the neighbor cell information reported by the terminal, and automatically compare it with the neighbor cell information issued in the measurement control to obtain the neighbor cell information. Area ...

Abstract

The invention discloses a method and a device for determining a configuration-neglected neighbor cell. The method comprises the following steps: acquiring a first cell identifier of a first cell which can be searched by user equipment from a measurement report formed when the user equipment resides in a main cell, wherein the first cell is a cell other than the main cell; judging whether the first cell is a cell meeting preset switching conditions according to the measurement report; and comparing the first cell identifier with a second cell identifier of a pre-configured neighbor cell, and determining the first cell as a configuration-neglected neighbor cell of the main cell when the first cell identifier is not included in the second cell identifier and the first cell is a cell meeting the preset switching conditions.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for determining a missing adjacent cell. Background technique [0002] In the current Long Term Evolution (LTE) network application process, with the further expansion of the network scale and the increasingly complex network structure, LTE network neighbor cell planning has become an important part of wireless network optimization. directly affect network performance. [0003] Missing configuration of adjacent cells will cause the user equipment UE to fail to switch normally, often resulting in dropped calls, which has a very bad impact on user perception. Obviously, good neighbor cell planning is one of the foundations to ensure LTE network performance and provide high-quality communication services. [0004] Compared with other communication systems, the handover measurement of LTE has an obvious feature, that is, the measurement in the LTE system is base...
