Terminal Device Paging Reception via GAP Configuration Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM card terminal devices, there is a high probability of failing to receive paging messages from another operator network due to outdated GAP or TDM pattern configuration information during cell reselection or handover, leading to communication disruptions.
Innovation Solution
The terminal device updates its GAP or TDM pattern configuration information by determining a target cell and sending relevant information to the network device, ensuring timely reception of paging messages by aligning with the network's timing offsets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device uses GAP configuration information or TDM pattern configuration information for cell communication, then the terminal device can receive paging messages from another operator network, but the configuration information changes during cell reselection or handover causing the terminal device to fail to receive paging messages in time
Solution Approach 1:
The terminal device performs cell reselection or handover in advance before the configuration information becomes invalid, and proactively updates the GAP configuration information or TDM pattern configuration information to the network device before leaving the current cell, ensuring continuous paging message reception without interruption
Solution Approach 2:
The network device provides feedback to the terminal device regarding the validity period of the configuration information, and the terminal device uses this feedback to determine when to update the configuration information, creating a closed-loop system that maintains synchronization between the terminal device and network device
2Reliability
If the terminal device updates GAP configuration information or TDM pattern configuration information during cell reselection or handover, then the terminal device can maintain synchronized timing with the network device, but the complexity of the cell reselection or handover process increases
Solution Approach 1:
The terminal device combines the configuration information update process with the existing cell reselection or handover procedure, so that the configuration information is updated as an integrated part of the cell transition process rather than as a separate operation, reducing overall process complexity
Solution Approach 2:
The same configuration information update mechanism is used for both cell reselection and handover scenarios, creating a universal solution that handles multiple situations with a single process, thereby reducing the need for separate complex procedures

AI summary
This application provides a communication method, apparatus, and system, and relates to the field of communications technologies, to improve a success rate of receiving a paging message by a terminal device. The method includes: After determining a target first cell, determining to reselect a first cell, or determining to have reselected a first cell, the terminal device sends first information to a network device. The first cell belongs to a first network. The network device belongs to a second network. The first information is determined by the terminal device. The first information includes first configuration information and/or first timing offset information. The first configuration information includes to-be-used gap GAP configuration information or to-be-used time division multiplexing TDM pattern configuration information of the terminal device. The first timing offset information includes a downlink timing offset between the first cell and a second cell. The second cell belongs to the second network, and a network device in the second network transmits data with the terminal device.
