The wireless side of the WiMAX network is a wireless metropolitan area network access technology based on the IEEE802.16d/e standard, which employs Orthogonal Frequency Division Multiplexing (OFDM) and OFDM Access (OFDMA) physics. Layer technology, effective against multipath fading. The best channel fading, the transmission rate can approach 75Mbps ₀

Figure 1 is a schematic diagram of the structure of a WiMAX network in the prior art. The logical architecture of the WiMAX network is as shown in Figure 1. The WiMAX network consists of the following three parts:

(1) Terminal: includes a Subscriber Station (SS) or a Mobile Station (MS), and the terminal uses the device to access the WiMAX network.

(2) Access service network: The Access Service Network (ASN) is defined as a set of network functions that provide wireless access services for WiMAX terminals. The ASN includes a base station (BS) and an ASN gateway (ASN-GW) network element. The main functions of the BS network element are: providing L2 connection between the BS and the MS, radio resource management, etc.; the main functions of the ASN-GW network element are: providing client functions for the MS authentication, authorization, and accounting (AAA) functions, Provides the relay (Relay) function of L3 information (such as Internet Protocol (IP) address allocation), intra-ASN handover, etc. for the MS. (3) Connection service network: The Connectivity Service Network (CSN) is defined as providing IP connection services for WiMAX terminals. The CSN mainly includes prepaid servers and logical entities such as authentication, authorization and accounting servers. The main functions provided are: MS IP address allocation, Internet (Internet) access, AAA proxy (proxy) or server (server), based on Authorization control of the terminal, etc. Along with the requirements of the openness of network services, a WiMAX network has also introduced a third-party application interface that can open the service of the WiMAX network to the network or the network. The Universal Service Interface (USI λ WiMAX network can pass) The USI system provides a service interface to an Application Service Provider (ASP)/Internet Application Service Provider (iASP). By calling the service capabilities provided by USI, ASP or iASP can be applied to WiMAX access terminals. Open services, and more convenient for WiMAX access terminals through ASP network or Internet.
