Group Handover Method for Mobile Terminal Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing handover methods in mobile communications systems face challenges with high signaling overhead and increased power consumption due to the simultaneous handover of multiple terminal devices, which can lead to service interruptions and network congestion.
Innovation Solution
A method where terminal devices collaborate to form a handover group, with one device assisting others in the handover process by sharing identification information and configuration data, reducing signaling impact on the network and minimizing service interruption time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple terminal devices perform handover independently using traditional methods, then each device can complete handover individually, but signaling overhead increases and network congestion occurs
Solution Approach 1:
The patent merges multiple independent handover processes into a single group handover operation. Terminal devices are grouped together and perform handover simultaneously under coordinated control, combining multiple individual signaling operations into a unified process that reduces total signaling overhead while ensuring reliable handover completion for all devices in the group
Solution Approach 2:
The patent creates a universal handover mechanism that serves multiple terminal devices simultaneously through a single handover group. The group handover procedure acts as a multi-functional solution that handles handover for all member devices through shared signaling resources and coordinated execution, eliminating the need for separate individual handover procedures
2Reliability
If traditional handover procedures are used for each terminal device, then individual handover can be completed, but power consumption of terminal devices increases
Solution Approach 1:
The patent combines multiple individual handover operations into a single group handover event. Terminal devices share common handover signaling and coordination procedures, reducing the total power consumption required for handover execution while maintaining reliable handover completion through coordinated group management and shared communication resources
3Productivity
If simultaneous handover of multiple terminal devices is performed using traditional methods, then all devices can be handed over, but service interruption time increases
Solution Approach 1:
The patent implements preliminary coordination and preparation for group handover before actual handover execution. Terminal devices are pre-grouped, handover parameters are pre-configured, and coordination mechanisms are established in advance, allowing simultaneous handover to proceed efficiently with minimized service interruption time while maintaining high handover throughput
Solution Approach 2:
The patent incorporates feedback mechanisms where the network controller monitors and coordinates handover progress of multiple terminal devices in real-time. This feedback enables dynamic adjustment of handover execution timing and resource allocation, optimizing the balance between handover throughput and service interruption time by coordinating device handover sequences based on real-time network conditions

AI summary
Embodiments of this application provide a handover method, a terminal device, and a network device. The method includes: obtaining, by a first terminal device, first identification information, where the first identification information includes identification information of at least one second terminal device; and performing, by the first terminal device, handover of the first terminal device and the at least one second terminal device based on the first identification information, where the handover is handover from a first network device to a second network device. According to the embodiments of this application, impact of signaling on a network side caused by simultaneous handover of a large quantity of terminal devices is reduced, and a service interruption time during handover is reduced, thereby effectively supporting simultaneous handover of a plurality of terminal devices.
