Communication resource releasing method and its system

Abstract

The invention discloses a communication resource release method and its system. The method includes the steps: a resource decision-making functional entity and a resource usage functional entity expand and negotiate a resource release mode by carrying a resource recovery mode in a transmission message; when determining to release a resource, the resource The decision-making function entity instructs the resource usage function entity to release the resource of the user / mobile station that supports the resource recovery method according to the negotiated resource release mode; the resource usage function entity releases the resource according to the instruction. The invention can release resources in real time, clear system garbage information and improve system efficiency.

Description

technical field [0001] The present invention relates to a communication method and system thereof, in particular to a communication resource release method and system thereof. Background technique [0002] Worldwide Interoperability Microwave Access (WiMAX, Worldwide Interoperability MicrowaveAccess, also known as 802.16 or IEEE802.16 standard in Chinese) is a wireless metropolitan area network (WMAN) technology, and it is a new airborne network proposed for microwave and millimeter wave frequency bands. The interface standard can provide high-speed Internet-oriented connection. Like Wi-Fi, WiMAX is used to transmit wireless signals to solve the problem of wireless metropolitan area network. Using this technology, users can perform wireless data communication at a very fast speed within a range of 50 kilometers. [0003] The prior art WiMAX network reference model can be found in figure 1 . As shown in the figure, a WiMAX mobile station (MSS, Mobile Subscribe Station) 10...

AI Technical Summary

Problems solved by technology

[0008] 1. For the mobile station: the mobile station is unreachable, the mobile station is disconnected or shut down without sending a network exit request, the battery of the mobile station is exhausted, and other reasons for the abnormality of the mobile station may cause session correlation between the access service network gateway and the home agent. Resources cannot be released normally

[0009] 2. In terms of access service network gateway: in scenarios such as mobile station switching, sudden traffic of prepaid users causing insufficient balance, and management reasons, session-related resources may not be released normally at the access service network gateway

[0010] 3. Home agent: Mobile IP (MIP, Mobile IP) sessions are deleted due to management reasons, mobile IP users switch to a new access service network gateway, and mobile IP users switch to a new access service network gateway but are not supported In scenarios such as deleting the binding information with the original access service network gateway due to the need for dual-casting, session-related resources may not be released normally in the home agent

[0011] It can be seen from the above that because the resource release in WiMAX relies on the aging mechanism, it is not real-time, and the resource release mechanism is not perfect, so there is a lot of garbage information in the network, and there are various R6 interface resources and R4 interface resources that should be released in time but have not been released. , mobile IP binding resources, header compression and header removal context resources, flow template resources, and billing UDR resources, etc., resulting in waste of system resources
