Solution Overview

Problem

In communication networks, especially with high mobility of mobile devices in clusters, there is an ineffective use of signaling resources due to redundant transmission of similar signaling information, which can lead to resource blocking.

Innovation Solution

Mobile devices are clustered based on shared properties like location and velocity, allowing only a subset to transmit signaling information, which is interpreted as valid for all devices in the cluster, thereby reducing redundant signaling and conserving resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signaling information is transmitted individually to every mobile device in a cluster, then each device receives accurate signaling information, but signaling resources are wasted due to redundant transmissions

Engineering Contradiction:
Improvesignaling information deliveryVSAvoidsignaling resource consumption
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent merges signaling transmissions by identifying clusters of mobile devices with similar mobility characteristics and transmitting signaling information to a representative device (such as the device with the worst channel conditions) in the cluster. The representative device then forwards the signaling information to other cluster members, eliminating redundant individual transmissions while ensuring all devices receive the necessary information.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The representative mobile device acts as an intermediary within the cluster, receiving signaling information from the base station and distributing it to other cluster members. This intermediary approach reduces the direct signaling burden on the base station while maintaining reliable information delivery to all devices in the cluster.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If uplink resources are allocated to all mobile devices in a cluster to send measurement reports, then each device can report its status, but uplink resources are blocked due to redundant reporting

Engineering Contradiction:
Improvemeasurement report accuracyVSAvoiduplink resource usage
Core Design Contradiction:
Loss of informationVSQuantity of substance

Solution Approach 1:

The patent combines measurement reporting by selecting a representative mobile device from each cluster to send measurement reports on behalf of all cluster members. Since devices in a cluster have similar mobility characteristics and channel conditions, the representative device's measurements are indicative of the entire cluster's status, eliminating the need for redundant individual reports.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent applies local quality by allowing different treatment for different clusters. Each cluster is identified based on specific mobility characteristics, and only the representative device within each cluster performs measurement reporting. This localized approach ensures adequate monitoring of each cluster's conditions while reducing overall uplink resource consumption.

Inventive Principle:
Principle #3Local quality

AI summary

The invention concerns a method for transmission of signalling information between a base station (BS1) and mobile devices (UE1-UE5), wherein a cluster of mobile devices (UE1-UE4) is defined comprising at least two of said mobile devices (UE1-UE5) that have at least one specifying parameter lying within a predefined range in common, and signalling information transmitted between at least one of the mobile devices (UE3, UE4) belonging to said cluster and the base station (BS1) are interpreted as signalling information of all mobile devices (UE1-UE4) belonging to said cluster, a base station (BS1) and a user terminal (UE1) therefor.
