Sensor Information Sharing in IMS Calls Through RTCP Payloads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication services, such as MCX and IMS, do not effectively utilize sensor data from First Responders' devices, limiting the sharing of critical information like temperature, light, and humidity during calls, which affects the immersive experience and hinders efficient disaster response.
Innovation Solution
A method and apparatus for sharing sensor information in MCX and IMS calls by incorporating a new payload to transmit sensor data, allowing UEs to exchange lists of sensors and their parameters, using RTCP packets, and enabling ambience sharing through IMS Application Reference Identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional MCX and IMS communication services are used, then basic voice and video communication is maintained, but sensor data sharing capability is lost
Solution Approach 1:
The patent extends the existing MCX and IMS communication services to support multiple functions including voice, video, and sensor data sharing through a unified payload structure. The sensor payload is integrated into the existing RTCP framework, allowing the same communication infrastructure to handle diverse data types without requiring separate dedicated systems.
Solution Approach 2:
The sensor data is encapsulated within the existing RTCP payload structure, creating a nested architecture where sensor information is contained within the broader communication protocol framework. This allows sensor sharing to be implemented without fundamentally redesigning the underlying communication infrastructure.
2Loss of information
If sensor information is shared in real-time during calls, then immersive experience and situational awareness are improved, but communication overhead and data transmission complexity increase
Solution Approach 1:
The patent extracts only the essential sensor parameters needed for situational awareness (temperature, humidity, light intensity, pressure) and transmits them through a streamlined payload structure. By selecting and transmitting only critical sensor data rather than all available sensor information, the system reduces data overhead while maintaining effective communication.
Solution Approach 2:
The system dynamically adjusts which sensor parameters are transmitted based on the communication needs and available bandwidth. The payload structure allows flexible configuration of sensor data inclusion, enabling optimization between information completeness and transmission efficiency.
3Adaptability or versatility
If existing payload structures are used for MCX services, then compatibility with current standards is maintained, but sensor data transmission capability is limited
Solution Approach 1:
The patent designs a sensor payload that can be integrated into existing MCX and IMS payload structures, creating a universal solution that works with current standards while enabling new sensor data sharing capabilities. The payload is designed to be compatible with existing RTCP frameworks while adding sensor data support.
Solution Approach 2:
The patent prepares and structures sensor data in advance according to standardized formats that are compatible with existing MCX and IMS protocols. By pre-formating sensor information according to established standards, the system ensures seamless integration with current communication infrastructure without requiring protocol changes.

AI summary
Sharing sensor information in a internet protocol (IP) multimedia subsystem (IMS) call includes receiving, by a first user equipment (UE), a sensor message in the IP IMS call and obtaining, by the first UE, the sensor information associated with a second UE from the sensor message.
