Solution Overview

Problem

Current 5G networks face inefficiencies in paging mechanisms, leading to increased signaling load and resource waste due to broadcasting user data to all access nodes, even when the targeted device is unlikely to receive it, which results in higher latency and interference.

Innovation Solution

A method where a network node selects a subset of transmission points based on the likelihood of reaching the wireless device, including user data only in paging messages from those points and transmitting regular paging messages from others, optimizing radio resource usage and reducing interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user data is included in paging messages from all access nodes, then the probability of successful data delivery increases, but radio resource usage and interference increase

Engineering Contradiction:
Improvesuccessful data delivery probabilityVSAvoidradio resource usage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies local quality by differentiating the paging message content based on the specific transmission point. Access nodes that are more likely to reach the wireless device include both user data and paging information, while other access nodes transmit only paging information. This localized differentiation optimizes radio resource usage while maintaining reliable data delivery.

Inventive Principle:
Principle #3Local quality

2Reliability

If user data is included in paging messages from all access nodes, then data delivery reliability improves, but signaling load increases

Engineering Contradiction:
Improvedata delivery reliabilityVSAvoidsignaling load
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent implements local quality by making the paging message content dependent on the transmission point's ability to reach the device. Only selected access nodes include user data in their paging messages, reducing the overall signaling load across the network while ensuring reliable delivery through the most effective transmission points.

Inventive Principle:
Principle #3Local quality

3Reliability

If user data is included in paging messages from all access nodes, then data delivery improves, but latency increases due to processing overhead

Engineering Contradiction:
Improvedata deliveryVSAvoidprocessing latency
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent reduces processing latency by applying local quality - only access nodes that are likely to successfully reach the wireless device include user data in their paging messages. This selective approach minimizes the number of nodes that need to process and transmit full paging messages with user data, thereby reducing overall processing overhead and latency.

Inventive Principle:
Principle #3Local quality

4Area of stationary object

If user data is included in paging messages from all access nodes, then comprehensive coverage is achieved, but interference increases

Engineering Contradiction:
Improvepaging coverage areaVSAvoidinterference
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent reduces interference while maintaining comprehensive coverage by applying local quality - differentiating the paging message content based on the transmission point's characteristics. Access nodes with higher likelihood of successful transmission include user data, while others transmit only paging information, thereby reducing overall interference levels while maintaining wide coverage.

Inventive Principle:
Principle #3Local quality

AI summary

The disclosure relates to methods, devices, and computer programs in mobile communications. More specifically, the disclosure relates to a method, performed in a network node, for transmitting data to a wireless device. The method comprises obtaining a paging area for transmitting paging data to the wireless device, the paging area comprising multiple transmission points. The method further comprises selecting a subset of the multiple transmission points, based on a selection criterion, and initiating transmission of a paging transmission in the paging area. The paging transmission comprises first data and second data targeting the wireless device when transmitted from the transmission points of the selected subset of the multiple transmission points. The first data comprises the paging data and the second data comprises information not comprised in the first data. Moreover, the paging transmission comprises only the first data when transmitted from other transmission points of the paging area.
