Mobile Device Backup Base Station Switching for Wireless Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems experience data transmission discontinuity and delays due to interruptions in the connection between mobile devices and base stations, necessitating a solution that maintains continuous data transmission without modifying existing hardware architectures.
Innovation Solution
A mobile device with a communication module and process module that selects a primary and backup base station based on received BS information, performing data transmission with the primary BS during available intervals and maintaining a connection with the backup BS during unavailable intervals, ensuring seamless data transmission recovery when the primary connection fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a mobile device uses a single base station for data transmission, then the device complexity is reduced, but data transmission reliability deteriorates when the connection is interrupted
Solution Approach 1:
The mobile device performs preliminary actions by establishing a backup connection to a second base station before the primary connection fails. The device selects and connects to a backup base station in advance, so when interruption occurs, data transmission can continue without breaking existing connections or performing complex reconfiguration procedures.
2Reliability
If the mobile device performs network entry procedure again when connection fails, then data transmission reliability is improved, but data transmission time increases due to reconnection delays
Solution Approach 1:
The device performs preliminary connection establishment with a backup base station before failure occurs. When the primary connection fails, the device can immediately switch to the pre-established backup connection, avoiding the time-consuming network entry procedure that would otherwise be required to re-establish connectivity.
3Reliability
If the mobile device switches to another base station when connection is interrupted, then data transmission reliability is improved, but device complexity increases due to additional connection management
Solution Approach 1:
The device manages connection complexity by pre-establishing a backup connection in advance. This preliminary action eliminates the need for complex real-time connection management during failure events, as the device simply switches from the primary to the pre-configured backup base station without performing complex selection or reconfiguration procedures.

AI summary
A mobile device, base stations, a backhaul network device for a wireless network system, and a method and a computer program storage product for the mobile device are provided. Each of the base stations is connected to the backhaul network device via a wired connection. The mobile device selects a primary base station and a backup base station from the base stations according to base station information of each base station. The mobile device performs a data transmission procedure with the primary base station during an available interval of a low-duty mode to communicate with the backhaul network device via the primary base station, and performs a connection keeping procedure with the backup base station during an unavailable interval of the low-duty mode. While the data transmission procedure fails, the mobile device performs a data transmission recovery procedure with the backup base station immediately so as to continuously communicate with the backhaul network device via the backup base station.
