Problems solved by technology

[0009] There are two main defects in the basic process of dynamic bandwidth allocation: one is that it is difficult to choose an appropriate bandwidth request-authorization cycle
In most of the wireless systems in the past, the QoS of the service was not considered as the focus

Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail with examples given below and in conjunction with the accompanying drawings.

[0031] The invention provides a new uplink bandwidth allocation method aiming at the different QoS requirements of multiple services in the broadband wireless access system. The following takes a broadband wireless access system including 1 BS and L SSs as an example to illustrate the uplink bandwidth allocation method, and assume that the subscriber station SS j (j=1, 2, ..., L) exists N j Uplink service flow connections, as shown in Figure 2. First, two important QoS parameters describing the service flow are given: the minimum sustained transmission rate R min and the maximum sustained transfer rate R max . Fig. 3 is the flow chart of whole uplink bandwidth allocation of the present invention, comprises the following steps:

Abstract

A method for distributing uplink bandwidth of wideband radio access system includes calculating out parameter of desired distribution bandwidth on next uplink sub frame at user station as per service quality parameter and historical connection state of user station service stream by base station, updating bandwidth parameter of current uplink sub frame at user station as per calculated out parameter and using it as bandwidth parameter of next uplink sub frame, reupdating bandwidth parameter of next uplink sub frame as per bandwidth parameter of system interface and using reupdated bandwidth parameter as actual bandwidth distributed to user station.

Description

technical field [0001] The invention relates to the field of wireless access bandwidth allocation, in particular to an uplink bandwidth allocation method of a broadband wireless access system. Background technique [0002] Broadband Wireless Access (BWA, Broadband Wireless Access) network has developed rapidly in the past ten years due to its advantages of flexibility, convenience, mobility, and low investment. With the diversification of services, it has become an inevitable trend to provide quality of service (QoS, Quality of Service) support for users in wireless networks. Due to the limitation of wireless air interface resources, the system can only meet the QoS requirements of multiple users for multiple application services by using a more effective wireless resource management method for resource utilization. [0003] FIG. 1 is a schematic diagram of a typical broadband wireless access cellular structure, which includes a base station (BS, Base Station) and multiple ...
