Solution Overview

Problem

Existing wireless communications networks struggle to efficiently support dynamic services that are not covered by pre-existing arrangements between subscribers and service providers, particularly in scenarios where devices need to access services temporarily or without prior agreements.

Innovation Solution

A method for operating communications devices in wireless networks that allows devices to receive a registration accept indication, determine if the service is required, and transmit a rejection indication if the service is not needed, enabling access to dynamic services without prior agreements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If wireless communications networks provide dynamic services without pre-existing arrangements, then service accessibility and adaptability are improved, but network resource utilization efficiency deteriorates due to unnecessary service attempts

Engineering Contradiction:
Improveservice accessibilityVSAvoidnetwork resource utilization
Core Design Contradiction:
Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The network performs preliminary evaluation of service requirements before fully establishing service connections. The infrastructure equipment assesses whether a device actually requires a dynamic service based on device type, current context, and service characteristics, and only then proceeds with full service setup. This preliminary screening action prevents wasted network resources on unnecessary service attempts while maintaining accessibility for devices that do require services.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If the network automatically registers devices for services, then service deployment speed is improved, but device control and user autonomy deteriorate

Engineering Contradiction:
Improveservice deployment speedVSAvoiddevice control
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system implements a feedback mechanism where the communications device receives service registration indications from the network and can provide feedback by confirming acceptance or rejecting the service. The device autonomously evaluates the registration request and communicates its decision back to the network, maintaining both rapid deployment capability and user control. This feedback loop ensures devices have agency over their service subscriptions while the network maintains efficient automated registration processes.

Inventive Principle:
Principle #23Feedback

3Loss of energy

If the network evaluates service requirements thoroughly before registration, then network resource efficiency is improved, but registration process complexity and time increase

Engineering Contradiction:
Improvenetwork resource efficiencyVSAvoidregistration process time
Core Design Contradiction:
Loss of energyVSLoss of time

Solution Approach 1:

The network performs partial evaluation of service requirements rather than complete thorough assessment before initial registration decisions. The infrastructure equipment makes preliminary determinations about whether a device likely requires a dynamic service based on key criteria such as device type and service characteristics, without conducting exhaustive evaluation. This partial action approach maintains reasonable resource efficiency while avoiding excessive processing time that would result from completely thorough evaluation of every possible service parameter.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

A method of operating a communications device, the method comprising receiving broadcast information transmitted in a cell of the wireless communications network, based on the broadcast information, determining that a service is provided via the wireless communications network, selecting the cell of the wireless communications network as a serving cell, receiving an indication in the cell that registration for the service is permitted, receiving information associated with the service and determining that the service is not required, transmitting a rejection indication indicating that the service is not required and receiving a network restriction indication transmitted in response to the rejection indication, the network restriction indication indicating that the communications device is not permitted to select the cell as a serving cell.
