Embodiment Construction

[0037] The present invention will be described below in conjunction with the accompanying drawings and specific embodiments.

[0038] Before describing the method of the present invention, in order to facilitate understanding, firstly, the composition of the wireless metropolitan area network involved in the present invention will be described. The wireless metropolitan area network formed according to the IEEE 802.16e protocol consists of an air interface side and a network side. Entities on the air interface side include a mobile subscriber station (MS) and a base station (BS), and the subscriber station and the base station interact through the air interface. Entities on the network side include gateways and various management entities, which interact through wires. What the present invention relates to is the relevant entity of the air interface side, so the uplink business mentioned in the present invention usually refers to the business initiated by the mobile user stat...

Abstract

The invention provides an upstream bandwidth distribution method of a wideband wireless metropolitan area network base station, which is used for realizing the upstream bandwidth distribution between the base station and the mobile user station, and the base station comprises global multi-class mobile user station business queues which are used for managing various businesses of the mobile user station; the method comprises the following steps: calculating the size of bandwidth resources which can be dispatched in the dispatching distribution process of the upstream bandwidth; the bandwidth distribution is sequentially carried out on initial competition ranging, a contention channel and a rapid feedback channel; calculating the residual bandwidth resources, and if the residual bandwidth exists, the bandwidth resources are distributed in the order of first processing UGS / ertPS business, then rtPS business and last nrtPS / BE business for the business in the global multi-class mobile user station business queues according to the height of priority scheme, until the bandwidth resources are completely distributed or the distribution of the bandwidth resources of all the businesses is finished.

Description

technical field [0001] The invention relates to broadband wireless metropolitan area network technology, in particular to an uplink bandwidth allocation method of a broadband wireless metropolitan area network base station. Background technique [0002] The broadband wireless metropolitan area network technology represented by the IEEE 802.16 series standards is considered to be one of the most promising access technologies in the next generation communication network. The advantages of multimedia communication services are attracting more and more attention from the industry. In theory, this technology can be applied to all broadband access markets such as wide area access, enterprise broadband access, family last mile access, hotspot coverage, and mobile broadband access. The WirelessMAN-OFDMA physical layer specification of IEEE 802.16 standard is based on Orthogonal Frequency Division Multiplexing (OFDM) technology. As a representative of multi-carrier transmission tec...
