Transceiver Idle Mode Information Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication devices with multiple SIMs face challenges in efficiently receiving information from different radio cells due to timing conflicts, leading to reduced data transfer rates and increased power usage from frequent transmission gaps needed to monitor multiple networks.
Innovation Solution
A communication device with a transceiver that establishes a communication channel via a first radio cell and receives idle mode information of a second radio cell via this channel, allowing for efficient data transfer and reduced power consumption by reading system information and synchronization data through a dedicated data channel, rather than creating transmission gaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication device monitors multiple radio cells simultaneously to receive paging information and system information, then the network coverage and communication reliability are improved, but the power consumption increases and data transfer rates decrease due to frequent transmission gaps
Solution Approach 1:
The patent applies preliminary action by obtaining idle mode information (such as system information and synchronization data) of the second radio cell before actually needing to monitor it. This is achieved by receiving and storing this information through the first communication connection when the device is in connected mode, so that when transmission gaps occur for monitoring the second cell, the device can use pre-fetched information instead, thereby reducing the frequency and duration of transmission gaps and lowering power consumption while maintaining reliable network monitoring
2Reliability
If the communication device creates transmission gaps to monitor idle mode information of multiple radio cells, then the network diversity and service continuity are improved, but the data transfer rate of active connections deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-obtaining idle mode information of the second radio cell through the first communication connection before transmission gaps are needed. This allows the device to store this information in advance, reducing the need to create frequent transmission gaps for monitoring, thereby maintaining service continuity through multi-cell monitoring while minimizing interruptions to active data transfers and preserving high data transfer rates
Solution Approach 2:
The patent uses the first communication connection as an intermediary to transfer idle mode information from the network to the device during periods when the device is in connected mode. This intermediary channel allows the device to accumulate necessary monitoring information without interrupting active data transfers, effectively decoupling the timing of information acquisition from the timing of monitoring requirements, thus maintaining both service continuity and high data transfer rates
