FBMS Termination in Wireless Multicast Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network systems face challenges in efficiently managing and terminating multicast services, particularly in effectively indicating when a station is no longer using a specific Flexible Broadcast Multicast Service (FBMS) element or when the access point can no longer provide the FBMS service, leading to potential resource mismanagement and unnecessary service continuation.
Innovation Solution
The implementation of a method and system that allows non-access point stations to indicate the termination of FBMS elements and for access points to manage service periods, using wireless network management capability information elements to request and respond to FBMS requests, ensuring accurate resource allocation and service termination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multicast service termination mechanisms are not implemented, then service continuity is maintained, but resource wastage occurs due to unnecessary service continuation
Solution Approach 1:
The patent implements preliminary termination indication mechanisms where stations send FBMS termination requests before actually stopping service usage, and access points send service end indications before terminating the service. This allows both parties to be notified in advance, ensuring proper resource cleanup while maintaining service continuity until the termination is actually executed.
Solution Approach 2:
The patent establishes a feedback loop where stations report their FBMS element usage status to access points, and access points confirm service termination to stations. This feedback mechanism ensures that services are terminated only when actually needed, preventing resource wastage while maintaining service reliability through coordinated termination actions.
2Productivity
If FBMS service termination is not properly indicated, then service operations continue, but resource mismanagement occurs
Solution Approach 1:
The patent implements a feedback mechanism where stations send FBMS requests indicating whether they are still using FBMS elements, and access points respond with service end indications. This ensures that resource allocation is continuously updated based on actual service needs, preventing resource mismanagement while maintaining efficient service operations.
Solution Approach 2:
Stations autonomously monitor their own FBMS element usage and initiate termination requests when no longer needed, rather than requiring external management. This self-service approach enables efficient resource management by allowing each station to manage its own service lifecycle based on actual usage patterns.
3Loss of substance
If termination indication mechanisms are implemented, then resource management is improved, but system complexity increases
Solution Approach 1:
The patent uses existing wireless network management message structures to carry FBMS termination indications, rather than creating entirely new communication protocols. The FBMS requests and service end indications are integrated into standard wireless management frames, allowing the termination mechanism to leverage existing infrastructure and reducing overall system complexity.
Solution Approach 2:
The access point acts as an intermediary that coordinates between multiple stations and the network infrastructure for service termination. By centralizing the termination coordination function at the access point, the system avoids the need for complex peer-to-peer coordination between stations, simplifying the overall termination mechanism while improving resource management efficiency.
