Cross-Base-Station Communication Path Switching for Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices (WDs) face challenges with battery consumption and antenna design due to their small size, leading to inefficient network communication and the need for a high-performance mobile phone for network access, and existing communication path switching methods are limited to scenarios where WDs and relay UE share the same eNB.
Innovation Solution
A communication path switching method and device that allows WDs to access a network through a different base station or relay UE by exchanging configuration information, enabling flexible network access even when base stations and/or MMES serving the WD and relay UE are different.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the WD directly connects to the network, then the WD can access the network independently, but the battery consumption increases and standby time decreases
Solution Approach 1:
The patent introduces a relay UE as an intermediary device between the WD and the network. The relay UE receives data from the WD and forwards it to the network, allowing the WD to access the network indirectly through the relay UE's connection, thereby reducing the WD's direct energy consumption while maintaining network access capability
2Volume of moving object
If the WD uses a single antenna, then the device size is reduced, but the transmission efficiency decreases compared to multi-antenna devices
Solution Approach 1:
The patent combines the antenna resources of multiple UEs (including the relay UE and other nearby UEs) into a unified communication resource pool. This allows the WD to benefit from multi-antenna transmission capabilities without physically having multiple antennas, as the system merges the antenna resources of multiple devices to serve the WD's communication needs
3Ease of operation
If the WD and relay UE camp on the same eNB, then communication path switching can be implemented through simple reconfiguration, but the solution is not applicable to complex application scenarios with different base stations
Solution Approach 1:
The patent extends the communication path switching functionality to work universally across different eNB configurations. The system can handle both simple scenarios where WD and relay UE camp on the same eNB and complex scenarios where they camp on different eNBs, making the path switching mechanism adaptable to various application scenarios through a unified approach

AI summary
A communication path switching method includes receiving, by a first base station, a first message from a first terminal, where the first message requests to switch the first terminal from a first path for independently accessing a network to a second path for accessing the network using a second terminal, and the first base station serves the first terminal; determining, by the first base station according to the first message, a second base station serving the second terminal; obtaining, by the first base station, configuration information from the second base station, where the configuration information enables the first terminal to access the network using the second terminal; and sending, by the first base station, the configuration information to the first terminal.
