Solution Overview

Problem

Reduced capability (REDCAP) devices consume more network resources and require network operators to control access, necessitating a method to manage their usage effectively.

Innovation Solution

A method for REDCAP devices involves receiving authorization information and system information to determine cell access, allowing or identifying alternative cells that support their capabilities, and establishing connections or sending notifications to manage access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If REDCAP devices are allowed to access the network, then device connectivity and service availability are improved, but network resource consumption increases

Engineering Contradiction:
Improvedevice connectivityVSAvoidnetwork resource consumption
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent applies local quality by configuring different access parameters and resource allocations for different device types. Specifically, the network configures cell-specific access information that distinguishes between REDCAP devices and other devices, allowing tailored resource management where REDCAP devices receive appropriate access permissions while consuming controlled network resources based on their specific capabilities and requirements.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent utilizes parameter changes by modifying access information parameters (such as cell access permissions, frequency configurations, and resource allocation parameters) based on device type. The network dynamically adjusts these parameters to allow REDCAP devices to access the network while optimizing resource consumption according to their reduced capabilities, thereby balancing connectivity with resource efficiency.

Inventive Principle:
Principle #35Parameter changes

2Productivity

If access control for REDCAP devices is implemented, then network resource management is improved, but access determination complexity increases

Engineering Contradiction:
Improvenetwork resource management efficiencyVSAvoidaccess determination complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring access information for different device types before actual access attempts. The network provides REDCAP devices with predetermined access parameters and cell configuration information in advance, enabling devices to self-determine accessibility without requiring complex real-time evaluations, thus simplifying the access determination process while maintaining efficient resource management.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling REDCAP devices to autonomously determine their access eligibility based on pre-provided access information and system parameters. Devices can independently assess whether they can access specific cells or frequencies using the configuration data received from the network, reducing the need for complex network-side access determination and simplifying overall access control.

Inventive Principle:
Principle #25Self-service
