Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing wireless communication systems face challenges in successful paging due to insufficient link budgets, weak uplink signals, and inefficient use of UE identifiers, leading to increased latency and resource consumption.

Innovation Solution

Implementing pre-paging messages with a shorter pre-paging UE ID derived from the paging UE ID, managed by the AMF, and maintaining a mapping of pre-paging configurations to reduce latency and conserve signaling resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional paging UE ID is used, then paging coverage is maintained, but link budget is insufficient in poor coverage conditions

Engineering Contradiction:

Improvepaging success rateVSAvoidlink budget

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The paging procedure is segmented into two phases: pre-paging phase using a shorter pre-paging UE ID for initial contact in poor coverage conditions, and traditional paging phase using the full paging UE ID for reliable communication. This segmentation allows each phase to use the appropriate identifier length for its specific purpose, improving overall paging success rate while managing link budget constraints.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If pre-paging resources are reallocated, then paging flexibility is improved, but signaling resource consumption increases

Engineering Contradiction:

Improvepaging flexibilityVSAvoidsignaling resource consumption

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Pre-paging configuration and resource allocation are performed in advance before the actual paging event. The network entity configures pre-paging resources and establishes the mapping between pre-paging UE ID and paging UE ID beforehand, so that when paging is needed, the pre-configured resources can be immediately utilized without reallocation, reducing signaling overhead while maintaining flexibility.

Inventive Principle:

Principle #10Preliminary action

3Loss of time

If pre-paging configuration is implemented, then paging latency is reduced, but device complexity increases

Engineering Contradiction:

Improvepaging latencyVSAvoidnetwork entity complexity

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

A mapping mechanism is introduced as an intermediary between the pre-paging UE ID and the traditional paging UE ID. The network entity maintains a mapping table that associates pre-paging configurations with corresponding paging UE IDs. This intermediary structure allows the system to benefit from reduced latency through pre-paging while managing complexity through a standardized mapping approach rather than complex real-time processing.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network entity may establish a first user equipment (UE) identifier (ID) associated with pre-paging. The first network entity may transmit, with information associated with the first UE ID, a request associated with paging to a second network entity. Numerous other aspects are described.
