Neighborhood access method in heterogeneous network, wireless access control center and system

Abstract

The invention provides a neighborhood access method in the heterogeneous network, a wireless access control center and a system. The neighborhood access method in the heterogeneous network includes acquiring base station information and request information of QoS (quality of service) of base stations around a user terminal and generating base station lists according to the base station information capable of meeting the request information of the QoS; acquiring moving speed of the user terminal, and determining moving states of the user terminal according to the moving speed of the user terminal and preset speed threshold value; selecting a neighborhood corresponding to the maximum value of the ratio of the diameter of the neighborhood to the moving speed of the user terminal as a target neighborhood if the user terminals are at high speed moving state, and controlling the user terminal to access to the target neighborhood. By the neighborhood access method, the user terminal can be provided with the optimum target neighborhood to access according to the request information of the QoS of users and the base station information when the user terminal launches service requests.

Description

technical field [0001] The invention relates to the communication technology in the communication network, in particular to a cell access method, a wireless access control center and a system in the heterogeneous network. Background technique [0002] In modern mobile communications, users' demand for data services is increasing rapidly, and wireless mobile networks are facing huge expansion requirements. Relying solely on the wireless access technology enhancement of macro base stations is not only difficult to meet the capacity requirements of hotspot areas, but also unable to achieve full coverage of blind spots. . [0003] Therefore, in the current communication network, a cell configuration method with a hierarchical cell structure is adopted, and a macro base station and a micro base station are used to divide the area of ​​the communication network into a macro cell and a micro cell. The macro cell is a layered cell with a larger effective signal coverage, and the mi...

Problems solved by technology

However, in traditional technologies, the access control of heterogeneous networks mainly uses signal strength as the decision parameter, but this mechanism will at least cause the following problems: First, if fast mobile users access micro cells, frequent access will occur, and users Communication performance declines; second, the network load of each wireless access point is unbalanced, resulting in a waste of some wireless resources
