Communication Processing Device for Body Area Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional body area network communication systems waste time allocating slots for emergency data transmission, require multiple channels for high-priority communication, and need special processing from non-emergency nodes during emergency data transmission, leading to inefficiencies and increased complexity.
Innovation Solution
A communication processing device that dynamically determines whether data should be transmitted over a control channel or a data channel based on the data type, allowing emergency data to be transmitted with higher priority using the control channel while non-emergency data follows standard allocation slots, reducing the need for special processing from other nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If time slots are allocated for emergency data transmission beforehand, then emergency data can be transmitted with high priority, but the allocated time is wasted when emergency data is not generated
Solution Approach 1:
The system dynamically switches between two operational modes: normal mode where data channels follow standard TDMA allocation, and emergency mode where the control channel is dynamically allocated for emergency data transmission. This dynamic adaptation allows the system to prioritize emergency data when needed while avoiding waste during normal operation.
Solution Approach 2:
The system changes the operational parameters of communication channels based on emergency status. When emergency data is detected, the control channel's priority parameter is changed from normal to high priority, and transmission timing parameters are adjusted to ensure immediate transmission without following standard slot allocation.
2Reliability
If multiple control channels and data channels are used for high priority emergency communication, then emergency data can be transmitted reliably, but the device complexity increases
Solution Approach 1:
The control channel is designed to serve dual functions: normal control signaling during standard operation and emergency data transmission during critical events. This multi-functionality eliminates the need for separate dedicated emergency channels, reducing overall system complexity while maintaining reliability.
Solution Approach 2:
The control channel dynamically changes its function based on emergency status. During normal operation, it performs standard control functions; when emergency data is detected, it immediately switches to high-priority data transmission mode, eliminating the need for static channel allocation and reducing device complexity.
3Reliability
If other nodes perform special processing during emergency data transmission on the control channel, then emergency data can be transmitted with high priority, but the ease of operation decreases
Solution Approach 1:
The node generating emergency data autonomously transmits it on the control channel without requiring coordination or special processing from other nodes. Other nodes continue their normal operations, and the emergency node independently manages the emergency transmission, greatly simplifying the operational complexity for the network.
Solution Approach 2:
The system segments emergency data transmission as an independent function performed by the emergency node itself, rather than requiring coordinated network-wide processing. This segmentation allows the emergency node to handle its own emergency transmission needs without burdening other nodes with special processing requirements.

AI summary
According to one embodiment, a communication processing device is provided which is mounted on a wireless communication device that performs communication using a first channel and performs communication by a communication scheme different from that of the first channel using a second channel. The communication processing device includes a control circuitry to determine whether or not transmission data is data that needs to be preferentially transmitted, specify at least one channel from the first channel and the second channel according to a determination result, and perform control so as to transmit the transmission data using the specified channel.
