Wireless Path Switching via Pre-established Backup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in maintaining communication quality due to obstacles, leading to increased power consumption and inefficient frequency utilization, as terminals need to constantly monitor multiple base stations and switch communication paths slowly, causing interruptions in services like video streaming and extended download times.
Innovation Solution
A wireless communication system that includes a terminal device connected to both a main base station and a backup base station, managed by a management device that facilitates quick path switching by pre-establishing connections and reducing power consumption by only activating the backup station when necessary, allowing for efficient communication path switching without frequent monitoring of control channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal simultaneously communicates with multiple base stations to form multiple wireless communication paths, then communication quality is stabilized, but power consumption at the terminal increases due to constant monitoring of control channels to multiple base stations
Solution Approach 1:
The system pre-establishes a backup communication path to a standby base station before it is needed. The terminal is configured with both a normal communication path and a backup communication path in advance, so that when the normal path deteriorates, switching can occur immediately without the terminal needing to continuously monitor multiple base stations, thus reducing power consumption while maintaining reliability.
2Reliability
If multiple base stations transmit the same packet data to a terminal to maintain communications, then communication reliability is improved, but frequency utilization efficiency decreases
Solution Approach 1:
The backup base station is pre-configured with the terminal's identification information and can immediately take over transmission when needed. Data is not redundantly transmitted by multiple base stations simultaneously; instead, the backup path is prepared in advance so that only one base station transmits at any given time, improving frequency utilization while maintaining communication reliability through rapid path switching.
3Reliability
If communication paths are switched upon detecting a decrease in quality of communication, then communication quality is maintained, but service interruption occurs if switching takes too long
Solution Approach 1:
The system establishes a backup communication path in advance before the normal path fails. The terminal is pre-configured with both normal and backup path information, and the backup base station is pre-synchronized. When the normal path deteriorates, the terminal can immediately switch to the backup path without time-consuming reconnection procedures, thus minimizing service interruption while maintaining communication quality.
4Reliability
If a terminal constantly monitors all control channels to multiple base stations to detect user data, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The system pre-configures the terminal with specific backup base station information including identification and access parameters. The terminal only needs to monitor control channels from the designated backup base station rather than all possible base stations, significantly reducing monitoring complexity while maintaining the ability to switch paths for communication reliability.

AI summary
To reduce power consumption and enable a quick change from one communication path to another when detecting a decrease in quality of communication for communicating user data, a first base station determines a second base station and a third base station, and then the first base station transmits a connection request message to a terminal, the second base station and the third base station concurrently with transmitting a communication request message to the second base station, and, while the second base station is in communication with the terminal, upon detecting a decrease in quality of communication with the terminal based on a reception status of an uplink signal from the terminal, the second base station transmits a path switching request message to the first base station, which in turn transfers the received path switching request message transmitted from the second base station to the third base station.
