Wearable Network Search via Host-Provided Cell List
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable devices in wireless communication systems face challenges in quickly and efficiently reconnecting to a wireless network after a short-range communication connection with a host device is released, leading to potential battery waste and connection delays.
Innovation Solution
A method and apparatus that enable a wearable device to perform an enhanced network search by receiving a neighboring cell list from a host device. This list is generated based on capability information previously received from the wearable device, allowing it to quickly discover suitable cells for wireless network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device performs a full network search after connection release, then the device can find any available network, but the search time and battery consumption increase
Solution Approach 1:
The host device performs preliminary action by pre-generating and storing a neighboring cell list based on the wearable device's capability information before the actual connection reestablishment is needed. This advance preparation allows the wearable device to immediately use the pre-computed list during network search, significantly reducing search time and battery consumption while ensuring reliable reconnection to suitable networks.
2Reliability
If the wearable device searches all available cells, then the device can select the optimal network, but the search process consumes excessive battery power
Solution Approach 1:
The system applies local quality by tailoring the network search process to the specific capabilities of the wearable device. The host device filters and selects only the relevant neighboring cells that match the wearable device's capability information (such as supported frequency bands, network types, and other device-specific parameters). This localized approach ensures the wearable device only evaluates networks it can actually connect to, maintaining high selection quality while dramatically reducing battery consumption compared to searching all available cells.
3Adaptability or versatility
If the host device stores capability information for all devices, then the system can support diverse device types, but the data storage and processing complexity increase
Solution Approach 1:
The system segments the capability information management by organizing data according to device types and categories. Instead of storing all possible device capabilities in a single monolithic structure, the host device divides capability information into manageable segments based on device types (e.g., wearable devices, mobile phones, tablets) and their specific capabilities. This segmentation approach maintains high adaptability to support diverse device types while reducing data management complexity through structured organization and efficient retrieval mechanisms.

AI summary
An example method performed by a first terminal in a wireless communication system may include identifying a connection state of a second terminal, receiving capability information from the second terminal, if the second terminal is connected with the first terminal using short-range communication, and is not connected with a serving cell of the first terminal over a wireless network, and transmitting a list of at least one candidate cell identified based on the capability information to the second terminal.
