Embodiment Construction

[0024] 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.

[0025] 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 perform the following cell splitting method flow, which is specifically used to determine whether the logical cell needs to be split, and when it is necessary to perform cell splitting, determine a unique new logical cell combination, and p...

Abstract

The embodiment of the invention, which relates to the technical field of communication, discloses a cell splitting method and apparatus. With the method and apparatus, the maintenance cost during the network planning construction process can be reduced. According to the embodiment of the invention, the method comprises: path loss parameters and path loss thresholds for data transmission between a target terminal and all RRUs in a logic cell are obtained respectively, wherein the logic cell is formed by all RRUs; according to the path loss parameters and path loss thresholds, an ownership between the target terminal and all RRUs is determined, and alternative cell splitting schemes are determined according to the ownership, wherein the alternative cell splitting schemes are used for dividing the logic cell into new logic cell combination units designated by the alternative cell splitting schemes; a user ratio value of each alternative cell splitting scheme is obtained, wherein the user ratio value is a ratio value of user numbers of two new logic cells; and according to the user ratio values, the logic cell is split into designated new logic cell combination units meeting a preset condition. The method and apparatus are suitable for a communication network system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a cell splitting method and device. Background technique [0002] With the development of communication technology, especially the popularization of cell combination technology, the receiving gain can be improved by realizing uplink data combination. Therefore, in the process of network planning and construction, multiple independent logical cell RRUs (RemoteRadioUnit, remote radio frequency unit) are usually connected to the same BBU (BuildingBasebandUnit, indoor baseband processing unit) at the same time to form a new logical cell, thereby expanding the cell In order to reduce the switching times of users, and then reduce the probability of dropped calls of users. [0003] At present, because multiple RRUs are connected to the same BBU at the same time, the original multiple cell resources are reduced to one cell resource. Therefore, in order to increase cell re...
