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

Abstract

The invention provides a method for admission control of a terminal with a Wimax (Worldwide Interoperability for Microwave Access) function, a base station and a system. The method comprises the following steps of: in a receiving step, receiving a Wimax request launched by a mobile terminal by the base station, wherein the Wimax request corresponds to a to-be-accessed service connecting request; in a second judging step, judging whether a minimum bandwidth limitation sum of all accessed service connections and service connections to be accessed of the mobile terminal is smaller than or equal to a threshold value; and in a connection establishing step, when the minimum bandwidth limitation sum of all the accessed service connections and the service connections to be accessed of the mobile terminal is smaller than or equal to the threshold value, admitting and converting the service connections to be accessed into the accessed service connections. Due to the adoption of the technology which is provided by the embodiment of the invention and is based on the user bandwidth limitation for controlling service to be accessed, the mobile terminal can designate a specific rule through the bandwidth limitation of a user class in a configuration file, realizes the user class control of the service to be accessed and improves the support of the Wimax function by the mobile terminal.

Description

Technical field [0001] The present invention relates to wireless communication technology, in particular to a method, base station and system for admission control of terminals with Wimax function. Background technique [0002] The bandwidth limitation in the Wimax 16e protocol, also known as QoS (Quality of Service), is used to ensure the quality of service of the service connection. The configuration attributes (Profile) specified by the Wimax 16e protocol only contain the corresponding parameters for the bandwidth limitation of the service connection. The bandwidth limit of each business connection is specified in the maximum maintenance rate and minimum retention rate fields in the profile of the business connection. [0003] According to the Wimax 16e protocol, only the maximum physical processing capacity of the mobile terminal (MS, Mobile Station) is limited. However, each terminal or user can have multiple service connections, but the Wimax 16e protocol does not limit user-...

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
