Smallcell scale networking system and method, Smallcell and centralized control center

Abstract

The invention discloses a Smallcell scale networking system. The Smallcell scale networking system comprises a plurality of Smallcells, a centralized control center and a Smallcell gateway, wherein each Smallcell is connected with the Smallcell gateway through the centralized control center; and the centralized control center is used for realizing convergence and distribution of data, and realizing centralized self-configuration and self-optimization flows. According to the Smallcell scale networking system, the centralized control center is used for controlling topological information of a current entire network, executing the centralized self-configuration and self-optimization flows, outputting cell parameters such as neighbor lists, working frequency points and emitting power of the Smallcells, and issuing the cell parameters to corresponding Smallcells, so that the manual maintenance cost is reduced, and the application demand of Smallcell scale deployment is met. The invention also discloses a Smallcell scale networking method, a Smallcell and the centralized control center.

Description

【Technical field】 [0001] The invention relates to the field of wireless communication, in particular to a Smallcell scale networking system and method, Smallcell, and a centralized control center. 【Background technique】 [0002] Smallcell is a low-power wireless access node, that is, a small indoor base station, which is connected to the Smallcell system gateway (Gateway) through a standard wired connection (such as DSL), and further connected to the operator's core network, providing indoor users with various The wireless access service of the business can increase the network capacity, provide high-speed service business, and allow users to have a better user experience. [0003] In the current field of wireless communication, 2G / 3G / 4G systems have the problem of signal blind area and weak area network coverage and extension in underground shopping malls, subways, tunnels, urban villages and other scenarios. With the widespread popularization of Internet broadband service...

Problems solved by technology

[0009] However, when small cells are deployed on a large scale, due to the uncertainty of the power-on and off time of the small cells, the small cells that are powered on first have the problem of limited listening, and cannot obtain the information of the small cells that are powered on later.

Therefore, if each Smallcell implements its own self-configuration function, it may cause conflicts in cell parameter configurations of different Smallcells. interfering issues

[0010] To avoid the above problems, it is feasible to deploy small-scale Smallcells by manually configuring cell parameters such as operating frequency, neighbor cell list, and transmit power; however, as the number of Smallcells increases, it is necessary to Manual configuration of cell parameters for each Smallcell will consume a lot of manpower, and every time a Smallcell is added or deleted, it needs to be manually reconfigured in real time to adapt to network changes

Therefore, when small cells are deployed on a large scale, the method of manually configuring small cell cell parameters cannot adapt to network changes in a timely manner, and the cost of human maintenance is extremely high
