Adaptive Multi-SIM Paging for Conflict-Free Network Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multi-SIM user equipment (UE) devices experience conflicts and inefficiencies in paging due to overlapping paging messages for different SIMs, leading to resource wastage and poor user experience, as existing systems struggle to adapt to multiple active SIMs and prioritize high-priority communications.
Innovation Solution
The UE provides an indication of its multiple SIM support to the network, allowing the network to adjust paging repetitions and conflicts, and sends a paging control message to manage SIM activity, using assistance information to coordinate optimal paging occasions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network sends paging messages for multiple SIMs simultaneously, then all SIMs can be reached, but paging conflicts and resource wastage occur
Solution Approach 1:
The network dynamically adapts the number of paging repetitions based on the UE's multi-SIM capability indication. When the network receives an indication that the UE supports multiple SIMs, it adjusts the paging repetition count to match the number of active SIMs, allowing flexible resource allocation that prevents both conflicts and wastage
Solution Approach 2:
The system changes the paging parameter (number of repetitions) based on the UE's reported SIM capability. The network entity modifies paging configuration parameters dynamically according to the multi-SIM indication received from the UE, optimizing resource usage for each specific UE scenario
2Reliability
If the network increases paging repetitions for multi-SIM UEs, then paging reliability improves, but network overhead increases
Solution Approach 1:
The paging repetition count is dynamically adjusted based on real-time UE capability information. The network entity receives an indication of multi-SIM support and adaptively sets the number of paging repetitions to match the actual number of active SIMs, avoiding both insufficient repetitions and excessive overhead
Solution Approach 2:
The UE self-identifies its multi-SIM capability by including an indication in its registration message to the network. This allows the network to automatically determine the appropriate paging configuration without manual intervention or complex signaling exchanges
3Reliability
If the UE monitors paging occasions for all SIMs, then no paging is missed, but device power consumption increases
Solution Approach 1:
The UE performs preliminary identification of its multi-SIM capability and communicates this to the network before paging occurs. The network uses this advance information to pre-configure the appropriate number of paging repetitions, allowing the UE to monitor only the necessary paging occasions without excessive power consumption

AI summary
A method, apparatus, and computer program product provide for adaptive paging for user equipment (UE) with multiple subscriber identification modules (SIMs). A UE may provide, in a registration message to the network, an indication that the UE supports multiple SIMs. The network may allow repeated paging to let a SIM miss a paging occasion without interpreting that the UE is unavailable. The indication from the UE can specify the number of SIM s supported by the UE. The network can adapt the number of paging repetitions to the UE. If the UE is accepting paging from another network or has a SIM that is already active with the network, the UE sends the network a paging control message. If the UE detects a paging occasion conflict, the UE sends the network a registration message with a replacement ID for paging another SIM, and the UE and the network negotiate appropriate paging.
