Problems solved by technology

[0011] To sum up, the existing bandwidth request technology fails to effectively use air interface resources to request bandwidth. If a large number of bandwidth request packets are suddenly sent at the same time, the uplink service data transmission rate of the SS will be seriously affected.

Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0042] The present invention provides two bandwidth request methods for the WiMAX system. The main design idea of ​​the two methods is: according to the real-time nature of the business, all services are divided into real-time and non-real-time services, and then based on real-time Services and non-real-time services to send bandwidth request messages. Wherein, when sending a bandwidth request message for a non-real-time service connection, the processing of the two methods of the present invention is the same: uniformly construct and send a bandwidth request message of a non-real-time service for all current non-real-time service connections. When sending a bandwidth request message for a real-time service connection, the processing of the two methods of the present invention is different: in the first method, a real-time service bandwidth request me...

Abstract

The invention discloses a bandwidth demand method in the global intercommunication WiMAX system through microwave, which divides the demand business into real-time business and non-real-time business. The method comprises the following steps: the A1.SS reports bandwidth demand for each real-time business; the SS reports bandwidth demand for non-real-time business; the B1. SS sends bandwidth demand report to BS. The invention can reduce bandwidth demand report occupation of vacant resource.

Description

Technical field [0001] The invention relates to a broadband access technology of a microwave access global interoperability (WiMAX) system, and particularly relates to a bandwidth request method of the WiMAX system. Background technique [0002] At present, the IEEE 802.16 protocol defines the air interface and media access control (MAC) layer of a point-to-multipoint broadband fixed wireless access system that is oriented to the metropolitan area and can provide multiple services. The IEEE802.16 protocol specifies the protocol layer of the air interface part of the WiMAX system, which mainly includes two parts: the physical layer (PHY) and the MAC layer. In a point-to-multipoint (PMP) system conforming to the IEEE 802.16 protocol, a base station (BS) can carry multiple subscriber stations (SS). Each SS can support the coexistence of the above four service types, and each service type can have multiple service connections. And define: the direction from BS to SS is downlink, and ...
