Method for admission control of terminal with Wimax (Worldwide Interoperability for Microwave Access) function, base station and system

Abstract

An admission control method, base station and system for a mobile station are provided. The method includes: a receiving step, wherein the base station receives a Wimax request sent from the mobile station, said Wimax request corresponding to a request for the service connection to be accessed; a second judging step, which judges whether the sum of the minimum bandwidth constraint of the current accessed service connection of the mobile station and the minimum bandwidth constraint of the service connection to be accessed by said mobile station is less than or equal to a threshold; a third step to establish a connection, which enables, when said sum of minimum bandwidth constraints is less than or equal to said threshold, admission and conversion of the service connection to be accessed to the current service connection. The method, base station and system provide a mobile station with subscriber stage control for services to be accessed by specifying, in the profile, specific rules for subscriber stage bandwidth constraints, and thus improve mobile station support of the Wimax function.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method, base station and system for performing admission control on a terminal with Wimax function. Background technique [0002] The bandwidth limit in the Wimax 16e protocol, also known as QoS (Quality of Service), is used to ensure the quality of service of the business connection. The profile specified in the Wimax 16e protocol only includes the corresponding parameters of the bandwidth limit of the business connection. The bandwidth limit of each service connection is stipulated in the fields of maximum maintenance rate and minimum reserved rate in the Profile of the service connection. [0003] According to the Wimax 16e protocol, only the maximum physical processing capacity of mobile terminals (MS, Mobile Station) is limited. However, each terminal or user can have multiple service connections, but there is no user-level bandwidth limitation in the Wimax 16e ...

AI Technical Summary

Problems solved by technology

[0003] According to the Wimax 16e protocol, only the maximum physical processing capacity of mobile terminals (MS, Mobile Station) is limited. However, each terminal or user can have multiple service connections, but there is no user-level bandwidth limitation in the Wimax 16e protocol. Provisions, that is to say, the Wimax 16e protocol does not impose bandwidth restrictions on the sum of the bandwidth of each service connection under the same MS: for example, there is no limit on the maximum maintenance rate and minimum reservation rate of the sum of the bandwidth of all service connections under the same MS

The protocol also does not support the function of limiting user-level bandwidth

[0004] In the process of realizing the present invention, the inventor has found that at least the following problems exist in the prior art: under the premise that almost all communication systems in actual commercial use have user-level bandwidth limiting functions, Wimax does not limit the user-level bandwidth. Access is controlled, which affects the commercial availability of the system
