Mission-Critical Video Functional Alias Sharing for Role Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing MCVideo services, users are unable to share their preferred roles or functional aliases while starting or joining a group call or requesting transmission/reception, which is crucial for identifying their roles in emergency situations.
Innovation Solution
The system enables users to choose and share their preferred functional aliases using XML elements in SIP messages, allowing these roles to be visible to other participants during group calls, with predefined roles managed by the Functional Alias Management unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If users participate in MCVideo group calls without sharing functional aliases, then the system operation is simple, but role identification and communication clarity are poor
Solution Approach 1:
The system performs preliminary encoding of functional alias information into MCVideo messages before transmission. The Functional Alias Management unit pre-processes and embeds role identification data into the message structure, so that when users join the group call, their functional aliases are already included and ready for immediate display and recognition by other participants.
2Loss of information
If functional alias information is encoded into MCVideo messages, then role identification is improved, but message processing complexity increases
Solution Approach 1:
The MCVideo message structure is designed to serve multiple functions simultaneously: it carries video data, control information, and functional alias information. By making the message structure multi-functional and universally applicable for different types of information transmission, the system avoids creating separate complex protocols for role identification, thereby reducing overall processing complexity while still encoding functional alias data effectively.

AI summary
The present disclosure provides a method for managing a Mission Critical Video (MCVideo) group call. The method includes transmitting (602), by at least one sender user equipment (UE) in the MCVideo group call, a MCVideo message to an MCVideo Server. The method includes receiving (604), by at least one receiver UE in the MCVideo group call, the MCVideo message from the MCVideo server, wherein atleast one of a plurality of functional alias ID is encoded and included in the MCVideo message. The method includes decoding (606), by the at least one receiver UE in the MCVideo group call, the atleast one of the plurality of functional alias　ID from the MCVideo message.
