Second UE Identity Adjusts Paging Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE and 5G networks, user equipment (UE) often face challenges in managing multiple UE identities with different paging timings, leading to conflicts and inefficiencies in power consumption due to simultaneous or misaligned paging time instants, which can result in either collisions or prolonged active periods, affecting the ability to monitor multiple networks or resources effectively.
Innovation Solution
The assignment of a second UE identity with a different paging timing allows for the adjustment of paging timing, enabling the UE to monitor downlink control information at distinct times for each network, thereby avoiding collisions and optimizing power usage by allowing a common warm-up period and reducing the need for prolonged active states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UE monitors multiple networks with different paging timings, then the UE can effectively monitor multiple networks or resources, but the UE experiences power consumption issues due to simultaneous or misaligned paging time instants causing collisions or prolonged active periods
Solution Approach 1:
The patent assigns a second UE identity specifically for paging purposes to separate the monitoring of different networks into distinct time segments. The first UE identity maintains the original paging timing while the second UE identity provides a different paging timing, allowing the UE to segment its monitoring activities across different time instances and reduce power consumption by avoiding prolonged active states.
Solution Approach 2:
The patent changes the paging timing parameter by introducing a second UE identity with a different paging timing configuration. This parameter change allows the UE to adjust when it monitors paging for different networks, transforming the timing parameter to optimize power consumption while maintaining the ability to monitor multiple networks.
2Ease of operation
If a UE uses a single UE identity for paging, then the paging timing is fixed and simple to manage, but the UE cannot effectively monitor multiple networks with different paging timings without experiencing collisions
Solution Approach 1:
The patent makes the UE identity system multi-functional by introducing a second UE identity that serves specifically for paging purposes. This second identity provides an additional function for monitoring different networks with different paging timings, while the first UE identity continues to serve its original purpose, creating a universal system that handles both single and multi-network monitoring scenarios.
Solution Approach 2:
The patent adds another dimension to the UE identity system by introducing a second UE identity with a different paging timing dimension. This dimensional addition allows the UE to operate in a multi-dimensional identity space where each identity can be associated with different timing characteristics, enabling effective monitoring of multiple networks without collision.

AI summary
A method includes receiving, by a user equipment (UE), at least a first UE identity assigned to the user equipment for a wireless network, the first UE identity associated with a first paging timing; and receiving, by the user equipment, a second UE identity that has been assigned to the user equipment at least for paging purposes that adjusts a paging timing from a first paging timing associated with the first UE identity to a second paging timing associated with the second UE identity, wherein the second paging timing is different from the first paging timing.
