With the development of technology and society, as well as the popularity of Internet, requirements of sounds,video and data are increasing. Wireless communication satisfy people’s desires of accessing network wherever and whenever. As a competive chi flat iron technology of Broadband Wireless Metropolitan Area Network, IEEE802.16 provides a uniform worldwide standard for Broadband Wireless Access. IEEE802.16 MAC layer protocol defines comprehensive polo shirts guaranteeing mechanism, including complete signaling system, scheduling service types and bandwidth request/allocation, and so on.The research on wireless resource management algorithms for chi flat iron is of great significance.Call admission control is very important for QoS guaranteeing. Its main task is to determine whether allow a new service flow or not according certain policy. The entry of new one may decrease current online services’QoS performance. However, network has to absorb chi hair straighteners businesses as many as possible. Call admission control can be used to find the trade-off to ensure the Qos of existent services, meanwhile maintain the bandwidth utilization at a high level.Based on the introduction of hair straighteners system and call admission control technology, this thesis is specially about call admission control of Qos realization. The main contents are as follows:1. The QoS mechanism of MAC layer was analyed in detail. A proposal was posed in order to perfect the QoS realization architecture.
