Embodiment 1

[0050] Because the wireless business is dynamic, sometimes the business volume is large, sometimes small, and the overall cost performance of the system is constantly changing. Therefore, the inventors of the present application propose that the relationship between adjacent base stations in adjacent cells can be dynamically adjusted according to changes in actual application scenarios, so that the performance, capacity, interference, and power consumption of a joint system of many base stations can dynamically approach the best ideal value.

[0051] Based on the above idea, this embodiment provides a multi-base station coordination method applied to a cellular system, including the following steps:

[0052] Step 1. When planning the cellular system, a group of adjacent base stations is regarded as a cluster, and a primary base station is configured therefrom, and the rest are configured as secondary base stations, wherein each secondary base station corresponds to a monitor;

...

Embodiment 2

[0070] This embodiment provides a base station, which can be used as the primary base station or the secondary base station in the foregoing embodiment 1, and can be dynamically adjusted specifically. The base station at least includes a transceiver unit and a main processor unit.

[0071] A transceiver unit for receiving traffic reported by other base stations;

[0072] The main processor unit, when the base station is the main base station, determines that the received service volume reported by other secondary base stations is lower than the pre-configured first threshold value, starts the service transfer operation of the secondary base station, and when the service transfer operation is completed Afterwards, the controller corresponding to the secondary base station shuts down the secondary base station.

[0073] On the basis of the above base station, it also includes: a multi-channel gate unit, which selects the secondary base station to be shut down when the base stat...

Embodiment 3

[0080] This embodiment provides a multi-base station coordination system applied to a cellular system, which includes a group of adjacent base stations, one of which is a primary base station, and the rest are secondary base stations. The functions of each part are described below.

[0081] The secondary base station is configured with a monitor, and when the cellular system is operating normally, the monitor updates and counts the traffic volume of the cell area corresponding to the secondary base station in real time, and uploads the statistical traffic volume information to the primary base station;

[0082] The primary base station, when judging that the received service volume reported by the secondary base station is lower than the pre-configured first threshold value, starts the service transfer operation of the secondary base station, and after the service transfer operation is completed, the primary base station passes the secondary base station The corresponding cont...

Abstract

A multiple base station collaboration method, system and base station for use in cellular systems, relating to the field of wireless communications. Said multiple base station collaboration method comprises: during cellular system planning, forming a cluster out of a group of neighboring base stations, configuring one of same to be a primary base station and configuring the rest to be auxiliary base stations; during normal cellular system operation, monitoring devices corresponding to each of the auxiliary base stations update, in real time, statistics regarding the service volume of the cell areas corresponding to a given auxiliary base station, and upload the statistical service volume information to the primary base station; when the primary base station determines that the reported service volume received from the auxiliary base station is lower than a preconfigured first threshold value, service transfer operations are initiated for said auxiliary base station; after service transfer operations are complete, the primary base station uses the controller corresponding to said auxiliary base station to shut down said auxiliary base station. The above technical solution improves wireless system power consumption and interference and achieves significant gains in efficiency.

Description

technical field [0001] The invention belongs to the field of wireless communication, and in particular relates to a multi-base station coordination method, system and base station applied to a cellular system. Background technique [0002] Due to the particularity of wireless communication, there is always more or less mutual interference between adjacent base stations. Therefore, at the beginning of the design, mutual cooperation between base stations and interference reduction are always given priority. In order to reduce the interference between base station cells, a series of methods are proposed: [0003] Frequency division method: Adjacent cells are assigned different frequency bands. [0004] Orthogonal scrambling code method: Adjacent cells are assigned different orthogonal scrambling codes. [0005] These methods can reduce the interference between cells to a certain extent, but there are certain limitations. In the frequency division method, different frequency...
