Switching Process Suspension Interval Following Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Multi-USIM devices face issues with efficient handover processes in 5G networks, leading to data transfer latency and resource misallocation due to the lack of coordinated switch gap configurations across base stations, resulting in inefficient use of time and frequency resources.
Innovation Solution
Implementing a mechanism to share and suspend switch gap configurations during and after handover operations, allowing base stations to coordinate the scheduling of Radio Resource Control (RRC) connections and time-frequency resources, enabling seamless switching between networks without leaving the RRC_CONNECTED state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continues switching between networks during handover, then network monitoring capability is maintained, but data transfer latency increases and resource allocation becomes inefficient
Solution Approach 1:
The patent applies preliminary action by suspending the switching process before it can cause harmful effects. The network temporarily pauses the UE's ability to switch between networks during a specified suspension interval following handover, preventing resource conflicts and data transfer delays while maintaining network monitoring capability through coordinated gap configurations.
2Adaptability or versatility
If the UE autonomously releases RRC connection during switching, then switching flexibility is improved, but connection stability deteriorates and network statistics are distorted
Solution Approach 1:
The patent implements feedback mechanisms where the network provides gap configuration information to the UE, and the UE reports its switching status. This feedback loop allows the network to coordinate gap configurations with the UE's switching activities, preventing autonomous RRC connection releases while maintaining switching flexibility through controlled, network-coordinated operations.
3Speed
If switch gap configuration is not coordinated during handover, then switching speed is maintained, but resource allocation efficiency decreases
Solution Approach 1:
The patent merges the gap configuration coordination function into the handover procedure itself. The network combines the suspension interval configuration with the handover commands, integrating previously separate functions into a unified process that maintains switching speed while improving resource allocation efficiency through coordinated time-frequency resource management.
Data Source
AI summary
A method for a user equipment (UE) is provided. The method includes the UE maintaining a first Radio Resource Control (RRC) connection with a first base station (BS) of a first network while receiving transmissions from a BS of a second network during at least one time period specified in a switch gap configuration. The UE receives an RRC reconfiguration message from the first BS that includes a first command and a second command. The first command instructs the UE to begin a handover procedure from the first BS to a second BS of the first network. The second command controls usage of the switch gap configuration by the UE. The UE initiates the handover procedure according to the first command. The UE may suspend reception of transmissions from the BS of the second network during a time interval following completion of the handover procedure based on the second command.
