Path managing method, method and system of path managing entity maintaining optimizing management

Abstract

The invention supplies a path managing method, path managing identity maintaining optimizing managing method based on WiMAX system. The core of the invention is that the reason value generating the path managing information would be carried in the path managing information sent by path managing identity. The invention could clear the path managing process. The aim of improving the maintainability and optimizing path managing identity operating would be realized.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a WiMAX system-based path management method, a path management entity maintenance optimization management method and system. Background technique [0002] With the vigorous development of Internet services and the wide application of wireless networks, the WiMAX system has received a lot of applications and attention due to its good wireless access characteristics. How the WiMAX system is applied to mobile users, and how to better provide the forwarding or routing function of packet services between the network and mobile users has become a new focus of research in the industry. [0003] The WiMAX network architecture system is attached figure 1 shown. [0004] figure 1 Among them, the WiMAX network architecture mainly includes: ASN (Access Service Network), CSN (Connection Service Network) and MSS (Mobile Subscriber Station). [0005] ASN is defined as: a colle...

Problems solved by technology

[0017] It can be seen from the path management messages in Table 1 that none of the above path management messages contains the necessary information for path management. For example, the path management entity cannot accurately determine the path Whether the response message is a response message for the success of the data path establishment or a response message for the failure of the data path establishment, even if it can be determined that it is a response message for the establishment failure, the path management entity cannot determine what operations should be performed in order to enable the data path The establishment is successful, so that the path management entity cannot perform accurate path management according to the messages it receives, and the path management entity cannot provide effective path statistics information to the network equipment operator, that is, the maintenance and optimization management end, so that the network equipment Operators cannot effectively maintain and optimize path management entities
