Embodiment Construction

[0067] In the following, a specific implementation manner of an access control method and device provided by the present invention will be described in detail with reference to the accompanying drawings.

[0068] In the embodiment of the present invention, the BE service in the WiMAX system can be directly accessed without going through the access control process.

[0069] For other QoS types of services in the WiMAX system, namely UGS services, RTVR services, ERTVR and NRTVR services, access control is required. The specific flow of the access control method provided by the embodiment of the present invention is as follows: figure 1 shown, including the following steps:

[0070] S101. Calculate an average physical bandwidth available for a new service flow in each frame.

[0071] S102. Determine whether the physical bandwidth calculated in step S101 can meet the physical bandwidth required by the QoS minimum reserved rate of the new service flow; when it is determined that i...

Abstract

The invention discloses an access control method and an access control device. The method comprises the following steps of: calculating the average physical bandwidth used for new traffic stream in each frame; determining whether the calculated physical bandwidth meets the requirement of the physical bandwidth required by QoS minimum preset speed of the new traffic stream or not; accessing the new traffic stream when the new traffic stream belongs to real-time service, the calculated physical bandwidth meets the requirement of the physical bandwidth required by QoS minimum preset speed of thenew traffic stream, and the requirements of the new traffic stream and QoS maximum time delay of the connected real-time traffic stream are met; otherwise, rejecting accessing the new traffic stream.The access control method and the access control device meet the requirement of the QoS minimum preset speed of the traffic stream accepted by the system, and meet the requirement of the QoS maximum time delay of the real-time service accepted by the system on the premise of fully utilizing the system bandwidth resources.

Description

technical field [0001] The present invention relates to broadband wireless access technology, in particular to an access control method and device. Background technique [0002] In order to meet the requirements of quality of service (Quality of Service, QoS) guarantee, admission control must be introduced before resource allocation to limit the service flow of the access network, that is, to decide whether to admit new service flow or existing service flow according to the current load status. If there is further demand for resources by business flows, the QoS of the accessed business flows is guaranteed by controlling the number of service flows served by the network at the same time, otherwise, the sum of the QoS requirements of these service flows may exceed the upper limit that the network can carry . [0003] There are five types of QoS services in the WiMAX system, which need to be considered separately when performing admission control. The services of the five QoS...
