Global microwave insertion interoperating system and method for realizing real-time roaming service

Abstract

A WiMAX network system is prepared as connecting external network switched in with mobile table to radio access device in mobile table external network and fixed interchange device in fixed communication network for finalizing conversion function of signaling message and address, connecting said fixed interchange device to fixed access device in fixed communication network for setting up connection between mobile tables through fixed communication network. The method for realizing real time and roaming service in WiMAX network is also disclosed.

Description

technical field [0001] The invention relates to broadband wireless access network technology, in particular to a global microwave access interoperability system and a method for realizing real-time and roaming services. Background technique [0002] The broadband wireless access system has the characteristics of high spectrum utilization, low radiation, and low cost. Therefore, the broadband wireless access technology is considered by the industry to be the preferred technology for next-generation wireless communications. [0003] WiMAX (Worldwide Interoperability for Microwave Access) is a broadband wireless access protocol used to ensure compatibility and interoperability between different broadband wireless access devices. There are two networking modes for WiMAX network: independent networking of WiMAX network or integrated networking with existing network. Currently more promising, and more research is the second way. [0004] figure 1 It is a typical WiMAX network i...

Problems solved by technology

[0009] 1. In terms of networking methods, the existing fixed communication network resources are not fully utilized, resulting in high cost and difficulty in network construction

[0010] Due to the small coverage of the WiMAX network, it is impossible to build a wide-area coverage network like GSM (Global System for Mobile Communications) alone. Therefore, it needs to be integrated with the existing network, especially with the existing fixed communication network resources. Networking to reduce the cost and difficulty of network construction, but the existing technology does not make full use of the existing fixed communication network resources

[0011] 2. In terms of business capabilities, it cannot provide real-time services well

[0012] Although the rise of the Internet has led to the continuous growth of IP data services, the proportion of traditional voice services in communication services still occupies the first place. Therefore, it is necessary to provide high-quality real-time services, especially IP voice services, and the above-mentioned network obviously cannot guarantee real-time Service Quality of Service (QoS)

Although in the prior art, a VoIP network system with carrier-grade QoS is obtained by setting up an IP private network, that is, establishing a Voice over IP (VoIP) line between the CSN of the foreign network and the CSN of the home network, the construction of the VoIP line requires investment. Larger construction capital and operating costs

[0013] 3. In terms of roaming service, it can only be realized through three-sided routing

[0014] Multiple telecom operators cannot share the network through user roaming, and the WiMAX network coverage is relatively small. The roaming service implemented by three-sided routing cannot guarantee the QoS of real-time services, and can only provide services that do not require real-time performance within a limited coverage area. high data traffic
