Method and system for accessing terminal to Worldwide Interoperability for Microwave Access (WiMAX) network

Abstract

The invention discloses a method for accessing a terminal to a Worldwide Interoperability for Microwave Access (WiMAX) network, which comprises the following steps that: when the terminal needs to access the WiMAX network, the processes of configuration selection, authorization, user information verification and resource distribution are sequentially completed through the information interaction between the terminal and a base station (BS) as well as between the BS and an access service network-gateway (ASN-GW), and the WiMAX network access is realized. The invention simultaneously discloses a system for accessing the terminal to the WiMAX network. When the method and the system disclosed by the invention are adopted, the functions of each process are clearly divided, the carrying relationship is simple, in addition, the data interaction process of the capability information is converted from an idle port to an R6 port, and the data required to be transmitted by the idle port is reduced, so the complexity for realizing the terminal and the BS is reduced.

Description

technical field [0001] The present invention relates to an access technology in communication, in particular to a method and system for a terminal to access a Worldwide Interoperability for Microwave Access (WiMAX, Worldwide Interoperability for Microwave Access) network. Background technique [0002] WiMAX technology, as a rapidly developing broadband wireless technology, has been commercially or trial commercially used in many countries. The use of WiMAX technology follows the 16e and Network Working Group (NWG) protocols. At the same time, the rapid development of WiMAX technology application also promotes the continuous upgrade of 16e and NWG protocols, and evolves in a new direction to adapt to the rapid development of market demand. [0003] The existing 16e and NWG agreements stipulate that the terminal access process includes: ranging (RNG) sub-process, terminal basic capability negotiation (SBC) sub-process, registration capability negotiation (REG) sub-process, an...

Problems solved by technology

When executing each of the above sub-processes, the terminal needs to send data containing its own capability information to the base station (BS), and then negotiate with the BS to finally determine the terminal's access. In this way, the air interface needs to transmit a lot of data

Due to the limited air interface resources and many interference factors on the air interface, too much air interface data interaction will cause certain difficulties in the design of the state machine between the terminal and the BS, that is, the implementation of the terminal and the BS is relatively complicated; moreover, for large In the scenario used by the user, too much data interaction will reduce the utilization of air interface resources

[0004] In addition, in the existing access process, the division of stage functions and the succession relationship are not clear. For example, when executing the DSA sub-process, it needs to rely on the capability negotiation results of other sub-processes executed before. In this way, the succession relationship Too many crossovers will increase the complexity of the state machine design of the terminal and BS
