UE Paging Collision Avoidance via Dynamic Time Slot Offsets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, user equipment (UE) may experience paging collisions due to overlapping paging occasions assigned to different Universal Subscriber Identity Modules (USIMs), leading to missed paging messages from one or more networks.
Innovation Solution
The UE dynamically requests a new identifier or offsets its assigned time slots to avoid collisions by communicating with the network, ensuring it can monitor for paging messages from multiple networks without overlap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE monitors paging occasions for multiple USIMs using assigned identifiers, then the UE can receive paging messages from multiple networks, but paging collisions occur when time slots overlap causing missed messages
Solution Approach 1:
The patent applies dynamics by making the time slot configuration adjustable and flexible. The UE can dynamically request offset values from the network to shift its paging occasions in time, transforming a static collision-prone schedule into a dynamic, adaptable one that avoids overlaps with other USIMs.
Solution Approach 2:
The patent changes the time parameter of paging occasions by introducing offset values. The network can modify the timing parameters of paging slots for different USIMs, shifting them in time to prevent overlaps while maintaining the periodic monitoring structure.
2Productivity
If the UE uses fixed paging time slots assigned by the network, then the network can efficiently manage resources, but the UE cannot avoid collisions with other USIMs
Solution Approach 1:
The patent segments the paging monitoring function by USIM, allowing each USIM to have its own dedicated time slots with potential offsets. This segmentation enables the network to maintain efficient resource allocation while providing separate, non-colliding monitoring opportunities for each subscription.
Solution Approach 2:
The system transitions from completely fixed time slots to a semi-dynamic configuration where offsets can be applied per-USIM. This maintains network control and resource efficiency while introducing the flexibility needed to avoid collisions between multiple subscriptions.
3Reliability
If the UE requests dynamic identifier changes or time slot offsets, then paging collisions can be avoided, but the communication protocol complexity increases
Solution Approach 1:
The UE autonomously determines when paging collisions occur and initiates requests for offset adjustments without requiring complex external coordination. The UE self-manages its paging configuration by requesting appropriate offsets from the network, reducing the burden on network controllers.
Solution Approach 2:
The system implements a feedback mechanism where the UE monitors its paging occasions, detects potential collisions, and communicates this information back to the network. The network then adjusts offsets based on this feedback, creating a closed-loop system that adapts to collision conditions.

AI summary
In an example method, a user equipment (UE) determines a first identifier assigned to the UE for use on a first wireless communications network and one or more first time slots for monitoring the first wireless communication networks. The UE determines a second identifier assigned to the UE for use on a second wireless communications network and one or more second time slots for monitoring the second wireless communication networks. The UE determines that the one or more first time slots at least partially overlap the one or more second time slots, and in response, transmits to the second wireless communications network, a request for a third identifier to be assigned to the UE for use on the second wireless communications network and/or a request that the one or more second time slots be offset by an interval of time.
