Transceiver Control Module for Handover to Higher Data Rate Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in seamlessly transitioning to higher data rate networks, especially for devices that require continuous connectivity, as they often remain on lower data rate technologies due to ongoing calls and good coverage, leading to suboptimal performance in handover processes.
Innovation Solution
A transceiver module and control module configuration that frequently monitors and measures signals from overlapping cells with different radio access technologies, enabling handover to higher data rate cells even if not initially configured, by degrading measurement results or using a secondary receiver module to identify and switch to better networks.

Engineering Contradiction Analysis
1Productivity
If inter-system or inter-frequency measurements are configured to enable handover to higher data rate networks, then data rate is improved, but service interruption occurs during measurement
Solution Approach 1:
The patent performs inter-system or inter-frequency measurements in advance during idle periods or when resources are available, before handover is actually needed. This preliminary measurement action allows the system to prepare handover candidates without causing service interruption during critical data transmission periods.
Solution Approach 2:
The patent dynamically adjusts the timing and frequency of measurements based on current service conditions, channel quality, and network state. Measurements are performed more frequently when service quality degrades or when higher data rate networks are detected, and less frequently when current service is satisfactory, thereby balancing measurement overhead with service continuity.
2Reliability
If frequent measurements are performed on cells of other communication systems to enable handover, then service quality is improved, but measurement overhead and complexity increase
Solution Approach 1:
The patent applies different measurement strategies to different cell types and geographic locations. For example, measurements on neighboring cells within the same system may be performed more frequently than measurements on cells from different communication systems. The measurement configuration is locally optimized based on cell-specific parameters such as signal strength, data rate capability, and handover history.
Solution Approach 2:
The patent changes measurement parameters such as measurement bandwidth, averaging window, and reporting threshold based on current service conditions. When service quality is satisfactory, measurement parameters are relaxed to reduce overhead. When service quality degrades or higher data rate opportunities are detected, measurement parameters are tightened to improve detection accuracy.
3Device complexity
If measurements are restricted to configured cells only, then device complexity is reduced, but adaptability to higher data rate networks is limited
Solution Approach 1:
The patent performs preliminary scanning and detection of available cells from different communication systems, even if not explicitly configured. This preliminary action builds a repository of potential handover targets that can be quickly evaluated when service quality degrades or when higher data rate networks are detected, without requiring complex real-time configuration management.
Solution Approach 2:
The patent enables the mobile transceiver to autonomously identify and evaluate cells from different communication systems based on broadcast information and signal measurements. The device self-manages the measurement configuration for unconfigured cells, automatically adjusting measurement parameters and reporting thresholds without requiring explicit network configuration, thereby improving adaptability while maintaining manageable complexity.

AI summary
Embodiments provide apparatuses, methods and computer programs for a transceiver (100) of a mobile communication system (500) and a backhaul modem. A mobile communication system (500) comprises at least a first radio cell (200a). An apparatus (10) for a transceiver (100) of a mobile communication system (500) comprises a transceiver module (12) to communicate with the at least first radio cell (200a) using a first data rate, and a control module (14) to control the transceiver module (12). The control module (14) is further configured to frequently obtain information related to measurement results on signals of a second radio cell (200b). The second radio cell (200b) is configured to provide a wireless service with a second data rate. The control module (14) is further configured to determine whether the second data rate of the second radio cell (200b) is potentially higher than the first rate. The control module is further configured to affect handover or reselection of the transceiver (100) from the first cell (200a) to the second cell (200b) if the second data rate is potentially higher than the first data rate.
