Dynamic Communication Gap Allocation for Multi-Subscription Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, terminal devices with multiple subscription identities face inefficiencies in handling simultaneous connections and idle states, leading to interruptions in RRC connections due to the need for paging monitoring across multiple networks, which negatively impacts ongoing communication.
Innovation Solution
The implementation of dynamic communication gap allocation, where terminal devices and networks negotiate and adjust the start, length, and periodicity of communication gaps based on radio conditions and synchronization requirements, allowing for minimal interruption during paging monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal device maintains connected state with first network and inactive/idle state with second network simultaneously, then multi-subscription capability is enabled, but communication interruptions occur due to paging monitoring requirements
Solution Approach 1:
The patent implements dynamic communication gap allocation where the network and terminal device negotiate and adjust the start, length, and periodicity of communication gaps based on radio conditions and synchronization requirements. This dynamic adjustment allows the system to adapt the gap configuration to current network conditions, enabling multi-subscription operation while minimizing disruptions to the connected state subscription.
Solution Approach 2:
The patent introduces periodic communication gaps during which the terminal device can perform paging monitoring activities on the inactive/idle subscription. By scheduling these monitoring activities in periodic intervals rather than continuously, the system enables multi-subscription capability while concentrating interruptions into specific time windows, thereby improving overall communication continuity during non-gap periods.
2Adaptability or versatility
If communication gaps are allocated for paging monitoring on second network, then multi-subscription operation is enabled, but duration and frequency of gaps reduce communication efficiency
Solution Approach 1:
The patent implements dynamic communication gap allocation where the network and terminal device negotiate and adjust the start, length, and periodicity of communication gaps based on radio conditions and synchronization requirements. This dynamic adjustment optimizes gap duration to be sufficient for paging monitoring while minimizing the time taken away from active communication on the connected subscription.
Solution Approach 2:
The patent allows negotiation and adjustment of gap parameters (start time, length, periodicity) based on current radio conditions and synchronization requirements. By changing these parameters dynamically rather than using fixed gap configurations, the system achieves multi-subscription operation with minimized impact on communication efficiency.
3Ease of manufacture
If fixed gap configuration is used for paging monitoring, then implementation is simple, but it cannot adapt to varying radio conditions and synchronization requirements
Solution Approach 1:
The patent transitions from fixed to dynamic gap configuration through negotiation between network and terminal device. The system determines gap parameters (start, length, periodicity) based on current radio conditions and synchronization requirements, providing adaptability while maintaining standardized procedures that preserve implementation feasibility.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal device reports synchronization status and radio conditions to the network, which then adjusts gap configurations accordingly. This feedback loop enables adaptation to varying conditions while maintaining structured interaction protocols that keep implementation complexity manageable.
