A multi-user access selection method under centralized network architecture

Abstract

The invention discloses a multi-use access selection method under centralized network architecture. The method comprises that (1), when users enter into cells for the first time, a user terminal automatically connects with macro base station links; the user terminal synchronously receives signal strengths of periphery base stations, base station ID information and base station type information; (2), the signal strengths of the base stations, the ID information corresponding to the base stations, base station type information and user Qos demand signs are sent to a convergence server through the macro base station links; (3), the convergence server evaluates and marks networks available for access according to the signal strength, available bandwidth, same-level user link delay of each base station, and selects the base stations corresponding to the networks with the highest marks as the proposed access base stations of the user terminal; and (4), the users access corresponding base stations according to selection results. According to the user access selection method provided by the invention, the Qos demands of different users can be satisfied well; the problem that the latter user squeezes the bandwidth of the former user is solved; and the load balance degrees of the homogeneous base stations are improved.

Description

Technical field [0001] The technical field of the access network of the present invention, more specifically, relates to a method for multi-user access selection under a centralized network architecture. Background technique [0002] In the access layer of the traditional network, the cell is centered on the base station. A base station covers a large area and serves multiple users. At the edge of the cell, when inter-cell interference is allowed, users are based on the received signal strength and access threshold. Select the network access with the maximum received signal strength. As the communication system moves towards the 5G era, the network is evolving to dense and heterogeneous. With the increase of users and the increasingly dense network, this access strategy brings more serious problems to the overall network efficiency and user performance. as follows: [0003] The first is the issue of user fairness. Users who arrive later will have a great bandwidth squeeze for the...
