Abstract

A broad band wireless city-domain network method provides the broad band wireless city-domain network system structure, the network protocol model, the basic station protocol shed structure, network topological structure and radio station phonetic communication flow. The phonetic communication is one level of the classification service, and the communication process includes: main call radio station applies for the control band width and operational band width to the entrance of the base station, the base station distributes the required band width according to the utilizing condition of the radio resources; the main call party sends the request, the base station inquires the IP address corresponding to the number called; the city-domain network starts the route discovery, resource pre-reservation and mark exchange path establishment process, found a double-layer exchanging path meeting the demand of special quality between the main caller and the one being called; the conversation begins, and the network starts the fare registering; when the conversation is concluded, the relative network resources are released.

Description

technical field

[0001] The invention belongs to the technical field of broadband wireless metropolitan area network (IEEE 802.16 WirelessMAN), and relates to a method for constructing a broadband WirelessMAN providing graded services. Background technique

[0002] 802.16 WirelessMAN is a broadband network capable of providing high-speed wireless access within a metropolitan area [1] Carl Eklund, Roger B.Marks, "IEEE Standard 802.16: A Technical Overview of the WirelessMANTM Air Interface for Broadband Wireless Access", IEEE C802. 16-02 / 05, 2002. The IEEE 802.16 working group released IEEE Std 802.16-2004 on October 1, 2004, which defines the air interface physical layer (PHY) and media access control layer of fixed broadband wireless access systems operating in the 2-66GHz frequency band (MAC) specification. IEEE Std 802.16e will be released in March 2005, which defines the air interface specification for mobile broadband wireless access systems. The working group of IEEE...
