Solution Overview

Problem

Paging multi-USIM wireless communication devices incurs increased control signaling overhead and energy consumption due to independent timing of paging occasions for each identity, leading to operational inefficiencies.

Innovation Solution

A method for co-scheduling paging occasions across multiple identities, allowing a wireless communication device to request and coordinate the same timing for multiple identities, thereby reducing the need for separate monitoring and signaling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If paging occasions are scheduled independently for each identity in multi-USIM UEs, then each identity can be paged separately, but control signaling overhead and energy consumption increase

Engineering Contradiction:

Improvepaging reliabilityVSAvoidenergy consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent merges paging occasions for multiple identities into a single co-scheduled paging occasion. Instead of separately scheduling paging occasions for each USIM identity, the network schedules a unified paging occasion that serves multiple identities simultaneously, thereby reducing energy consumption while maintaining paging reliability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a universal paging occasion that serves multiple functions - it can page multiple USIM identities within a single time-frequency resource. This multi-functional approach allows the same paging occasion to handle paging for different identities, reducing overall signaling overhead and energy consumption.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If paging occasions are scheduled independently for each identity, then each identity has dedicated monitoring time, but control signaling overhead increases

Engineering Contradiction:

Improvepaging deliveryVSAvoidcontrol signaling overhead

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent combines multiple identity-specific paging occasions into a single co-scheduled paging occasion. By merging the paging resources for multiple identities into one unified occasion, the network reduces control signaling overhead while ensuring reliable paging delivery through the shared occasion.

Inventive Principle:

Principle #5Merging (Combining)

3Adaptability or versatility

If separate paging occasions are used for multiple identities, then each identity can be monitored independently, but operational complexity increases

Engineering Contradiction:

Improveidentity managementVSAvoidoperational complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal paging occasion that handles multiple identities through a standardized procedure. This approach maintains adaptability for different identities while reducing operational complexity by using a single monitoring procedure rather than separate procedures for each identity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
