WLAN Service Tunnel Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current WLAN technologies lack a specific method for releasing service tunnels, leading to resource occupation by redundant information in devices when tunnels are no longer needed or need to be terminated.
Innovation Solution
A method for releasing a service tunnel in WLAN, where an originating end point sends a release tunnel request, receives an acknowledgement, and releases resources, with the PDG removing authorization information and sending a tunnel disconnection report to update related service information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If service tunnels are established to provide wireless access and connectivity services, then service functionality and user access capability are improved, but resource occupation and information redundancy in devices worsen when tunnels are no longer needed
Solution Approach 1:
The patent implements a structured tunnel release mechanism where the originating end point sends a release request, the receiving end point processes and acknowledges, and both ends clean up their respective resources. This ensures that when service tunnels are no longer needed, resources are systematically discarded and made available for reuse, preventing resource occupation and information redundancy while maintaining service functionality during active use
2Reliability
If service tunnels are maintained to ensure continuous connectivity, then connection reliability is improved, but resource waste and information redundancy increase when tunnels should be released
Solution Approach 1:
The patent employs feedback mechanisms through acknowledgment messages in the tunnel release process. When a release request is sent, the receiving end point responds with an acknowledgment to confirm resource cleanup. This feedback loop ensures reliable resource release while preventing resource waste, as the system only releases tunnels when properly terminated rather than maintaining them indefinitely

AI summary
The present invention discloses a method for releasing a service tunnel in WLAN. This method comprises: an originating end point that desires to release a service tunnel in a WLAN sending a release tunnel request to a corresponding end point of the service tunnel; the corresponding end point returning a release acknowledgement to the originating end point, and releasing resources of the service tunnel, a Packet Data Gateway (PDG) sends a tunnel disconnection report to a service authentication and authorization unit, and upon receiving the tunnel disconnection report, the service authentication and authorization unit updates self-stored information related to the released service tunnel. The method in accordance with the present invention makes it possible to implement the release of a designated service tunnel and release or update the related resources and information in time.
