MCData Server Resource Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public safety networks face challenges in efficiently managing resources for mission critical data communication, especially when a large number of users require services simultaneously, due to limited resources and the need for effective communication path establishment and termination.
Innovation Solution
A method is introduced that involves receiving a communication release message from first MCData user equipment, transmitting a communication release request to other MCData UEs, receiving a response, and releasing media plane resources associated with the communication, allowing for efficient resource allocation and management by the MCData server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If resources are allocated to support a large number of users simultaneously in MCData communication, then the number of users served increases, but resource availability per user decreases and resource management complexity increases
Solution Approach 1:
The patent segments the resource management process into distinct phases: establishment phase (allocating resources when communication starts) and release phase (freeing resources when communication ends). The MCData server independently manages these phases without requiring coordination with other network entities, thereby reducing overall system complexity while supporting multiple users simultaneously.
Solution Approach 2:
The MCData server autonomously performs resource allocation and release operations based on communication establishment and termination events. The server self-manages media plane resources without external intervention, and independently notifies relevant network entities (such as eNodeBs) about resource status changes, eliminating the need for complex inter-entity coordination mechanisms.
2Productivity
If centralized resource management is implemented by the MCData server, then resource allocation efficiency improves, but the signaling overhead and communication overhead increase
Solution Approach 1:
The patent extracts the resource management functionality from the general communication protocol stack and consolidates it into the MCData server application layer. The server directly manages media plane resources and handles release signaling independently, removing the need for complex integration with lower-layer resource management mechanisms and reducing overall signaling overhead.
Solution Approach 2:
Instead of having network infrastructure entities manage resources and notify application servers, the patent inverts the approach: the MCData server (application layer) actively manages resources and notifies network entities about resource status changes. This inversion reduces signaling overhead by eliminating redundant notification mechanisms.
3Reliability
If communication paths are established for multiple users simultaneously, then service availability increases, but resource consumption increases and resource release becomes more critical
Solution Approach 1:
The patent implements preliminary resource allocation when MCData communication is established, ensuring resources are ready before actual data transmission begins. The MCData server proactively reserves media plane resources and configures necessary network paths in advance, enabling immediate service delivery when users need communication, thereby maintaining high availability without unnecessary resource consumption.
Solution Approach 2:
The patent implements automatic resource recovery mechanisms that promptly release media plane resources when MCData communication terminates. The MCData server monitors communication status and immediately recovers allocated resources upon detecting communication end events, ensuring resources are quickly made available for other users while preventing resource leaks that would waste network capacity.

AI summary
Disclosures herein provide methods and servers for releasing mission critical data (MCData) communication in a wireless communication system. The release of MCData communication is initiated by MCData UE by using the hyper text transfer protocol (HTTP) or the release of MCData communication is initiated by a MCData server with or without prior notification to the MCData UE.
