Multi-SIM UE Capability Signaling for Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing simultaneous communication of a wireless device with multiple networks is challenging, particularly in deciding which communications to prioritize, and existing technologies often lead to network performance deterioration due to resource allocation issues.
Innovation Solution
A method where a multi-SIM user equipment (UE) signals its capability to networks without requiring specification changes, by providing full capability information to registered networks and indicating reduced capabilities through In-Device-Coexistence (IDC) assistance information, specifically highlighting carrier frequencies that need to be released due to multi-SIM usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-SIM UE signals full capability to multiple networks simultaneously, then network resource allocation is optimized, but resource conflicts occur due to limited UE resources
Solution Approach 1:
The patent implements dynamic capability indication where the UE transitions from signaling full capability to signaling reduced capability based on actual operational state. The network receives updated capability information when the UE enters multi-SIM simultaneous communication mode, allowing the network to dynamically adjust resource allocation to match actual UE capabilities, preventing resource conflicts while maintaining optimization.
Solution Approach 2:
The patent changes the capability parameter from static full capability to dynamic reduced capability. By modifying the capability indication parameter to reflect actual available resources during multi-SIM operation, the network can allocate appropriate resources without over-provisioning, resolving the contradiction between optimization and reliability.
2Ease of operation
If a UE maintains simultaneous communication with multiple networks, then user experience is improved, but network performance deteriorates due to resource allocation issues
Solution Approach 1:
The patent implements a feedback mechanism where the UE informs the network about its actual capability state during multi-SIM operation. The network receives feedback regarding reduced capability and adjusts resource allocation accordingly, creating a closed-loop system that maintains network performance while supporting multi-SIM user experience.
3Adaptability or versatility
If existing technologies are used for multi-SIM communication, then device compatibility is maintained, but resource conflicts occur due to lack of capability indication
Solution Approach 1:
The patent introduces capability indication information as an intermediary between the UE and network. This intermediary mechanism translates the complex multi-SIM operational state into network-understandable capability parameters, simplifying resource management while maintaining device compatibility through standardized signaling procedures.

AI summary
Embodiments herein relate to method performed by a UE (102) having multipleSIMs for simultaneous communication with two or more wireless communicationsnetworks. The UE (102) provides, to a first network node (104) associated with afirst wireless communications network associated with a first SIM, information on5full capability of the UE (102), wherein the UE (102) is registered with the firstwireless communications network. The UE further provides, to a second networknode (106) associated with a second wireless communications network associatedwith a second SIM, the information on the full capability of the UE (102), whereinthe UE (102) is registered with the second wireless communications network such10that the UE (102) is simultaneously registered with the first wirelesscommunications network and the second wireless communications network. TheUE further splits the full capability among the first and second SIMs into a firstreduced capability and a second reduced capability, and provides a first indicationof the first reduced capability to the first network node; and/or a second indication of the second reduced capability to the second network node.
