Multi-SIM Paging Coordination via Timing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks struggle with managing multiple SIMs on a single mobile device, leading to conflicts and inefficiencies in paging notification reception across different networks, resulting in degraded data throughput and missed communications.
Innovation Solution
A mobile communication device receives and transmits notifications to coordinate paging occasions across multiple wireless networks, adjusting timing and frame periodicity to prevent collisions and ensure simultaneous reception of paging notifications from multiple networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-Rx UE switches reception to another network before an on-going DL reception is completed, then paging reception on the second network can be received, but data throughput on the first network is degraded
Solution Approach 1:
The network performs preliminary actions by predicting paging occasions and proactively indicating to the UE when to switch reception networks. The network calculates timing information for paging occasions on the second network and provides this information to the UE before the actual paging occurs, allowing the UE to switch reception at the optimal time without interrupting ongoing DL reception on the first network.
2Reliability
If multiple networks send paging notifications simultaneously to a MUSIM UE, then both networks can deliver paging information, but conflicts occur causing missed paging or degraded performance
Solution Approach 1:
The system implements feedback mechanisms where the UE monitors paging occasions on both networks and reports back to the networks about paging reception status and conflicts. The networks use this feedback to adjust their paging timing and avoid simultaneous paging transmissions that would cause conflicts, thereby improving paging delivery reliability while managing coordination complexity.
3Adaptability or versatility
If a UE monitors paging occasions on multiple networks, then paging from both networks can be received, but timing collisions occur between networks
Solution Approach 1:
The network changes timing parameters of paging transmissions based on UE capabilities and network conditions. By adjusting paging frame offsets, periodicity, and timing advance values, the network ensures that paging occasions for different networks do not collide, allowing the UE to monitor paging on multiple networks without timing conflicts.

AI summary
According to one configuration, a wireless network environment includes a first wireless network and a second wireless network. A mobile communication device in the wireless network environment receives first paging notifications directed to the mobile communication device from a first wireless base station such as operated by a first wireless network service provider. The mobile communication device receives second paging notifications directed to the mobile communication device from a second wireless base station such as operated by a second wireless network service provider. The wireless network environment provides improved paging over conventional techniques.
