Embodiment Construction

[0035] The invention designs a dynamic resource reservation admission control method for the IEEE 802.16e system, in which a system global reserved bandwidth is set to simultaneously meet the bandwidth requirements of real-time variable rate services and switching services. figure 1 It is a flow chart of the steps of the method of the present invention, as shown in the figure, including:

[0036] Step 101, reserving a set additional bandwidth for each real-time variable-rate service other than the minimum guaranteed bandwidth, and obtaining the real-time service reserved bandwidth according to the sum of the additional bandwidth of all real-time variable-rate services;

[0037] Step 102, setting the handover service reserved bandwidth that can guarantee the handover service access ratio;

[0038] Step 103, according to the changes of the real-time service reserved bandwidth and the handover service reserved bandwidth, obtain the system global reserved bandwidth according to pr...

Abstract

The invention discloses a dynamic resource reservation and access control method and device of wide-band wireless access system, wherein the method includes: reserving predetermined extra bandwidth for each real-time variable rated service besides minimum guaranteed bandwidth, getting preserved bandwidth for real-time service according to summing extra bandwidth of all real-time variable rated service; setting reserved bandwidth for switching service which could ensure access ratio of switching service; acquiring global reserved bandwidth of the system based on predetermined rule according to reserved bandwidth of real-time service and switching service. The invention can perfectly satisfy bandwidth need of real-time service, ensure quality of service, satisfy IEEE802.16e system's support to mobility, greatly enhance access ratio of switching service, and ensures persistence and accessibility of service connection during switching process.

Description

technical field [0001] The invention relates to broadband wireless access technology, in particular to a dynamic resource reservation admission control method and device in a broadband wireless access system. Background technique [0002] For a long time, solving the "last mile" problem in broadband data access has mainly relied on wired access technologies, such as cables, digital subscriber lines (xDSL), and optical fibers. With the rapid development of the wireless communication industry, broadband wireless access technology has also joined the ranks of this competition. The WiMAX (Worldwide Interoperability for Microwave Access) technology based on IEEE 802.16 series standards supports fixed and mobile broadband wireless access, and the coverage of base stations is on the order of several kilometers, providing a new solution for broadband data access. [0003] IEEE 802.16e broadband wireless access system is designed to meet the rapidly growing demand for wireless multi...
