Embodiment Construction

[0039] Such as figure 1 As shown, the automatic detection method for cross-area coverage in the wireless cellular network of the present invention comprises the following steps:

[0040] (1) When the user terminal wants to switch from the source cell A to the target cell B, the base station where the source cell A is located obtains the distance dAB between the source cell A and the target cell B, and judges the distance dAB between the source cell A and the target cell B The relationship between the distance threshold value D between, if dAB<=D, then the process ends, otherwise enter step (2), the distance threshold value D is the average value of the distance between the source cell A and the nearest 6 base stations 3 to 5 times;

[0041] (2) Obtain the azimuth angles AzimuthA and AzimuthB, the lobe angles SectorA.BW and SectorB.BW, and the coverage radii RA and RB of the source cell A and the target cell B respectively, and calculate the connection lines between the source...

Abstract

The invention discloses an over-area covering automatic detection method in a wireless honeycomb network. The over-area covering automatic detection method comprises the following steps of: when a user terminal wants to be switched to a target cell B from a source cell A, a base station in which the source cell A is located acquires the distance dAB between the source cell A and the target cell B, and judges the relation between the distance dAB and the distance threshold D; whether the main lobe range of the target cell B and the cover range of the base station in which the source cell A is located have overlapped areas is judged, and if not, the threshold N of the number of cell layer between the source cell A and the target cell B is set to be 0; and the cell layers n between the source cell A and the target cell B is calculated, whether n is larger than N is judged, and if so, the existence of the over-area covering problem in the target cell B is proved. The over-area covering automatic detection method is convenient to acquire parameters, and can be obtained without calculation, thus guaranteeing the computational efficiency. In addition, the threshold parameters D and N are self-adaptive, so that the over-area covering automatic detection method is applicable to urban areas, suburban areas and the adjacent positions of the urban areas and the suburban areas theoretically, thus fully embodying the advantages of SON technologies.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method for automatically detecting crossover coverage in a wireless cellular network. Background technique [0002] With the rapid development of communication technologies and services, the scale of wireless networks is getting larger and larger. In order to better meet people's needs, the Long Time Evolved (LTE for short) network introduces a home base station (Home eNB), and various technical systems coexist, which makes the network very complicated. If the traditional network planning and optimization method is still used, operators will spend a lot of operating costs, and the efficiency of manual operation of massive network parameters will be reduced, and the network maintenance effect cannot be guaranteed. Therefore, while paying attention to equipment performance, operators will pay more attention to the efficiency of network maintenance and operation. How to redu...
