3GPP MCS Client Entity Request Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3GPP MCS standard networks, client entities belonging to multiple communication groups face challenges in discriminating between identical requests, leading to potential multiple identical media sessions and network performance issues.
Innovation Solution
A method that allows a destination client entity to discriminate between requests by adding belonging group information to each request, enabling it to choose the appropriate request and reject duplicates, thereby preventing multiple identical sessions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a client entity belonging to multiple communication groups receives identical requests from different groups, then the client entity can establish multiple identical media sessions, but this leads to network performance degradation and resource waste
Solution Approach 1:
The patent segments the request handling process by introducing belonging group information as a distinguishing parameter. Each request is tagged with the specific communication group it originates from, allowing the client entity to segment and identify duplicate requests across different groups. This enables the client to accept requests from different groups while rejecting duplicates from the same group, thus maintaining multi-group participation without creating redundant media sessions.
2Ease of operation
If the network transmits identical requests to all communication groups a client belongs to, then the client can potentially accept requests from any group, but this creates multiple identical media sessions and increases network load
Solution Approach 1:
The patent implements a feedback mechanism where the client entity sends rejection notifications back to the network for duplicate requests. When the client receives identical requests from different communication groups, it uses the belonging group information to identify duplicates and sends rejection feedback to the network for the redundant requests. This feedback loop enables the network to understand which requests should not be processed, preventing the creation of multiple identical media sessions while maintaining the simple broadcast transmission approach.
3Reliability
If the network adds belonging group information to each request, then the client entity can discriminate between requests, but this increases the complexity of the request structure
Solution Approach 1:
The patent applies local quality by adding belonging group information specifically to the request structure where it is needed for discrimination. Rather than fundamentally changing the entire request protocol, the invention locally enhances the request structure by incorporating group identification data. This targeted modification provides the necessary discrimination capability while minimizing the overall complexity increase, as the added information is confined to a specific field within the request structure.

AI summary
A method for discriminating, by a first destination client entity, requests in a communication network according to the 3GPP MCS “3rd Generation Partnership Program Mission-Critical System” standard, wherein the requests received by the destination client entity include a first mission-critical service request originating from the non-controlling server of the second communication group and a second mission-critical service request originating from the non-controlling server of the third communication group, each request received including at least one piece of belonging group information of the non-controlling server emitting the request.
