Ad Hoc Group Call Initiation in MCX Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G mobile communication systems lack a procedure for mission critical services (MCX) users to initiate ad hoc group calls without forming a temporary group, limiting user selection and operation efficiency.
Innovation Solution
The method and system enable ad hoc group calls in MCX by allowing users to select participants or functional aliases directly, with the MCPTT client generating an ad hoc group ID and establishing a media plane, and the MCPTT server managing participant notifications and mandatory additions based on configuration parameters, supporting off-network operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a temporary group is formed to initiate a group call in MCX services, then the group call can be established using existing procedures, but the system complexity and time required for group formation increase
Solution Approach 1:
The patent extracts the group formation step from the call initiation process. Instead of requiring users to form a temporary group before calling, the system allows direct ad hoc group call initiation by extracting only the necessary participant selection and call setup functions, eliminating the intermediary group creation step.
Solution Approach 2:
The patent segments the group call initiation process into independent components: participant selection, ad hoc group ID generation, and call establishment. This segmentation allows each component to be handled separately without requiring full group formation procedures, reducing overall system complexity.
2Productivity
If a temporary group is formed for group calls, then existing group call procedures can be used, but the time required to initiate calls increases due to the intermediary formation step
Solution Approach 1:
The system performs preliminary actions by pre-configuring functional aliases and participant lists before call initiation. When a user initiates an ad hoc group call, the necessary group identification and participant routing are already prepared, eliminating the need for time-consuming temporary group formation during the call setup process.
Solution Approach 2:
The patent enables skipping the temporary group formation step entirely by implementing direct ad hoc group call procedures. The system rushes through the essential call setup functions by using generated ad hoc group IDs and pre-configured participant information, bypassing the time-consuming intermediary group creation process.
3Ease of operation
If users can select participants directly without forming a group, then operation efficiency improves, but the system must handle ad hoc group ID generation and management
Solution Approach 1:
The system implements self-service by enabling users to directly select participants and initiate ad hoc group calls using pre-configured functional aliases. The system automatically handles ad hoc group ID generation and participant management without requiring users to manually form groups, making the process user-friendly while managing complexity on the system side.
Solution Approach 2:
The patent implements a universal ad hoc group call mechanism that can handle various participant selection scenarios (individual users, functional aliases, participant lists) through a single unified procedure. This multi-functional approach allows the system to manage different types of participant selections and group configurations using the same ad hoc group management framework, reducing overall system complexity.

AI summary
The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems for providing support for ad hoc group calls in mission critical services. The method includes listing, by an MCPTT client, a list of MCPTT participants or a functional alias to initiate an ad hoc group call in a MCX on network. The method further includes initiating, by the MCPTT client, the ad hoc group call with a list of MCPTT participants or the functional alias by sending a group call request to an MCPTT server.
