Multi-SIM UE Colliding Gap Management via RRC Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in managing colliding gaps in multi-subscriber identification module (SIM) terminals, particularly in next-generation wireless communication systems.
Innovation Solution
A method and device for multi-SIM terminals to manage colliding gaps by receiving a radio resource control (RRC) message from a base station, identifying whether to initiate a transmission of a UE assistance information message, and configuring preferences for multi-universal subscriber identity module (MUSIM) gaps and priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-SIM terminals operate multiple SIM cards simultaneously, then service coverage and communication flexibility are improved, but gap collision management complexity increases
Solution Approach 1:
The patent introduces a base station as an intermediary that receives UE assistance information from the multi-SIM terminal and provides gap configuration recommendations. This mediator coordinates the gap management between multiple SIM cards, reducing the terminal's management complexity while maintaining service coverage benefits
Solution Approach 2:
The patent implements dynamic gap configuration where the base station adjusts measurement gap patterns based on terminal feedback and network conditions. The gap configuration can be modified through RRC reconfiguration messages, allowing the system to adapt to changing communication requirements while managing collisions efficiently
2Measurement precision
If terminals transmit UE assistance information messages frequently to report gap preferences, then gap management accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent implements periodic gap measurement and reporting mechanisms where the terminal monitors gap collisions over a period and transmits UE assistance information at appropriate intervals. This periodic approach maintains accurate gap management information while avoiding excessive signaling by batching reports rather than transmitting continuously
Solution Approach 2:
The patent establishes a feedback loop where the terminal reports gap collision situations to the base station, which then provides optimized gap configurations. This feedback mechanism improves gap management accuracy by using actual measured data while controlling signaling overhead through targeted feedback messages rather than continuous transmission

AI summary
The disclosure relates to a 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A user equipment (UE) and a method performed by a terminal (multi-universal subscriber identity module (USIM) UE (MUSIM UE)) supporting a first universal subscriber identity module (USIM) and a second USIM in a wireless communication system is provided. The method includes receiving, from a base station, a radio resource control (RRC) message for configuring the UE to provide a preference for a multi-universal subscriber identity module (MUSIM) gap and a MUSIM gap priority, identifying whether to initiate a transmission of a UE assistance information message for providing first preference information on the MUSIM gap priority or second preference information indicating to keep all colliding MUSIM gaps based on a timer T346h, and, in case that the timer T346h is not running, initiating the transmission of the UE assistance information message for providing the first preference information or the second preference information.
