UE Relay Data Radio Bearer Management for Wearable Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices face limitations due to small battery capacity and antenna design challenges, leading to short battery life and reduced network access efficiency, with current solutions requiring multiple data radio bearers to manage varying quality of service (QoS) and limiting the number of devices that can be supported by a single intelligent terminal.
Innovation Solution
Implementing a method where a first UE acts as a relay for a second UE, using a specific identifier to manage data radio bearers, allowing the second UE to access the network through the first UE without allocating a separate bearer, thereby reducing energy consumption and increasing the number of wearable devices that can be supported by each intelligent terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the wearable device directly communicates with a base station, then network access capability is improved, but battery consumption increases and standby time decreases
Solution Approach 1:
The patent introduces an intelligent terminal as an intermediary device between the wearable device and the base station. The wearable device communicates with the base station through the intelligent terminal's data radio bearer, eliminating the need for the wearable device to maintain its own direct radio connection. This mediator approach enables network access while significantly reducing the wearable device's energy consumption and hardware requirements.
2Reliability
If the intelligent terminal allocates separate data radio bearers for each wearable device service, then quality of service is improved, but the number of wearable devices that can be supported decreases
Solution Approach 1:
The patent makes the intelligent terminal's data radio bearer universal by allowing it to serve multiple wearable devices simultaneously. Instead of dedicating separate bearers to each wearable device, the same data radio bearer is shared among multiple wearable devices, with the intelligent terminal managing the multiplexing. This multi-functional approach maintains quality of service while dramatically increasing the number of wearable devices that can be supported.
Solution Approach 2:
The patent merges multiple wearable device data streams into a single data radio bearer of the intelligent terminal. By combining the resources and management functions, the system achieves efficient multi-device support without sacrificing service quality. The intelligent terminal consolidates the data radio bearers that would otherwise be required for each individual wearable device.

AI summary
The present invention discloses a method for accessing a network by UE, a core network entity, a base station, and first UE. The method includes: determining, by a base station, that first UE provides relay for the second UE; and sending, by the base station, a first message including a first identifier to the first UE, where the first message is used to manage a data radio bearer DRB of the first UE, so that the DRB of the first UE is used to transmit data of the second UE, and the first identifier is in a one-to-one correspondence with the second UE. Therefore, energy consumption of the second UE can be reduced, and a quantity of second UEs that can be borne by the first UE can be increased.
