Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems for wearable devices waste network resources by establishing multiple bearers for different data directions, reducing the number of devices that can be supported.
Innovation Solution
Implement a multiplex bearer between a terminal device and a wearable device, using indication information in the data to distinguish different destination receive ends, eliminating the need for multiple bearers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple bearers are established for different data directions between wearable device and base station, then data transmission reliability is improved, but network resources are wasted and device support capacity is reduced
Solution Approach 1:
The patent merges multiple separate bearers (DRB-a and DRB-b) into a single multiplex bearer that can handle both uplink and downlink data transmissions. This is achieved by using a single bearer between the wearable device and relay UE, and another single bearer between relay UE and base station, eliminating the need for separate bearers for each data direction while maintaining transmission reliability through proper routing based on destination addresses.
Solution Approach 2:
The patent makes the bearer multiplexed and universal by enabling it to serve multiple functions - handling both uplink and downlink data, and supporting multiple destination addresses (wearable device, relay UE, or base station). The single bearer between relay UE and base station can route data to different destinations based on the destination address in the data packets, making it a multi-functional resource that reduces overall bearer quantity.
2Measurement precision
If multiple bearers are established for different data directions, then data routing accuracy is improved, but device support capacity is reduced
Solution Approach 1:
The patent changes the routing parameter from bearer-specific routing to destination-address-based routing within a multiplex bearer. Instead of having different bearers for different destinations, the system uses a single bearer with flexible routing that determines the final destination (wearable device, relay UE, or base station) based on the destination address contained in the data packets. This parameter change maintains routing accuracy while increasing device support capacity.
3Ease of operation
If separate bearers are established for uplink and downlink data, then data transmission control is improved, but network resource efficiency is reduced
Solution Approach 1:
The patent introduces dynamic routing control within the multiplex bearer, where the data transmission path is flexibly determined based on real-time destination requirements. The system dynamically selects whether to deliver data to the wearable device, relay UE, or base station based on the destination address, providing adaptive control without requiring separate static bearers for each scenario. This dynamic approach maintains transmission control while improving resource efficiency.
