Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] The embodiment of the present invention is applicable to a communication network system, in which a BBU, at least two RRUs and server / network equipment are set. Wherein, the server or the network device can be used to execute the following cell merging method flow, which is specifically used to determine whether the logical cell needs to perform cell merging, and when it is necessary to perform cell merging, determine the cell pair to be merged that need...

Abstract

The embodiment of the invention discloses a cell merging method and device and relates to the technical field of communication, which can lower the maintenance cost during network planning and construction. The method disclosed by the embodiment of the invention comprises the following steps: obtaining a neighbor list corresponding to a target logic cell; obtaining a switching failure rate between every two logic cells in a cell set formed by the target logic cell and adjacent logic cells; determining that two logic cells with switching failure rates greater than a first threshold are to-be-merged cell pairs; obtaining the resource utilization rates of the to-be-merged cell pairs and the retention situation of a target terminal in the preset time; and determining that the to-be-merged cell pairs meeting preset conditions are merged according to the resource utilization rates of the to-be-merged cell pairs and the retention situation. The cell merging method and device are applicable to a communication network system.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a cell merging method and device. Background technique [0002] With the development of communication technology, especially distributed base stations gradually replace traditional macro base stations, multiple RRUs (RemoteRadioUnit, remote radio frequency unit) can be connected to the same BBU (BuildingBasebandUnit, indoor baseband processing unit) at the same time to form multiple A logical cell, wherein each RRU is a logical cell. [0003] Currently, multiple logical cells can be combined so that the uplink data of the same user can be combined, thereby improving the receiving gain. However, in order to rationally merge multiple logical cells, it is necessary to confirm the distribution of users through a method of manual site survey, and then merge multiple logical cells according to the distribution of users. However, using the above method to merge multip...
