Terminal Device Proximity Communication Base Station Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices face challenges in determining whether a drop in signal intensity is due to moving out of coverage or environmental obstacles, leading to unnecessary searches for new base stations and periods of disabled communication.
Innovation Solution
The terminal device uses proximity communication with other devices to receive base station information, comparing it with its own to decide whether to maintain or switch connections, thereby inhibiting unnecessary searches by determining if the signal drop is due to moving out of coverage or local reception issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device searches for a new base station device when signal reception becomes poor, then the device can potentially find a new base station to maintain communication, but communication is disabled during the search and unnecessary searches occur when the terminal is actually within coverage
Solution Approach 1:
The terminal device performs preliminary actions by acquiring base station information from other terminal devices via proximity communication before actually needing to search. When the terminal device experiences poor signal reception, it can proactively check whether other nearby terminals are connected to different base stations, and if so, it can initiate a search for those base stations in advance or avoid unnecessary searches if it determines it's still within coverage area.
Solution Approach 2:
The system implements feedback by having terminal devices share base station information with each other through proximity communication. When a terminal device experiences poor signal reception, it receives feedback from other terminals about which base stations they are connected to, allowing it to make informed decisions about whether to search for new base stations or wait for signal recovery.
2Measurement precision
If the terminal device performs base station search when signal intensity drops, then it can switch to a new base station if outside coverage, but it cannot discriminate between being in poor reception area versus outside coverage leading to unnecessary searches
Solution Approach 1:
Other terminal devices act as intermediaries to provide base station information to the terminal device experiencing poor signal reception. By communicating with nearby terminals through proximity communication, the terminal device can indirectly obtain information about available base stations and determine whether it is outside coverage area or merely in a poor reception location, thereby improving the accuracy of coverage status determination.

AI summary
A first communication interface communicates with one of a plurality of base station devices according to a first communication scheme. A second communication interface communicates with a further terminal device according to a second communication scheme different from the first communication scheme. A controller selects a base station device that the first communication interface should communicate with based on base station information received in the second communication interface from the further terminal device and related to the base station device that the further terminal device is communicating with.
