PLMN Selection Procedure for Mobile Device Resource Optimization

Solution Overview

Problem

Modern multimode mobile devices face challenges in optimizing resource allocation to prevent performance degradation, particularly in scenarios where incompatible network access technologies and frequency bands lead to inefficient battery usage and poor user experience.

Innovation Solution

A method and system for generating a public land mobile network (PLMN) selection procedure that identifies compatible PLMNs by comparing access technologies and frequency bands, disabling resources for incompatible networks, and optimizing resource usage to enhance battery efficiency and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile device scans all available PLMNs to ensure comprehensive network coverage, then network selection reliability is improved, but power consumption increases and battery life decreases

Engineering Contradiction:

Improvenetwork selection reliabilityVSAvoidpower consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by pre-configuring the mobile device with a resource list containing access technology configurations of available PLMNs before the device needs to select a network. This allows the device to perform compatibility checks in advance and only scan PLMNs that match its supported access technologies, avoiding wasteful scanning of incompatible networks and thereby reducing power consumption while maintaining reliable network selection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by making the PLMN scanning process adaptive based on device capabilities. The mobile device dynamically determines which PLMNs to scan by comparing its supported access technologies against the pre-stored resource list, enabling flexible adjustment of scanning behavior to match device capabilities and minimize unnecessary power consumption

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the mobile device scans all PLMNs including incompatible access technologies, then network coverage completeness is improved, but device performance degrades due to inefficient resource allocation

Engineering Contradiction:

Improvenetwork coverage completenessVSAvoiddevice performance

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies preliminary action by pre-configuring the mobile device with a resource list containing access technology configurations of available PLMNs before the device needs to select a network. This allows the device to perform compatibility checks in advance and only scan PLMNs that match its supported access technologies, avoiding wasteful scanning of incompatible networks and thereby reducing power consumption while maintaining reliable network selection

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent extracts only the relevant PLMNs from the complete list of available networks by comparing device capabilities with the pre-stored resource list. This extraction process removes incompatible PLMNs from the scanning set, allowing the device to focus resources on scanning only those networks it can actually access, thus improving performance without sacrificing coverage completeness

Inventive Principle:

Principle #2Taking out (Extraction)

3Adaptability or versatility

If the mobile device maintains support for multiple access technologies to ensure compatibility with various networks, then adaptability is improved, but device complexity increases

Engineering Contradiction:

Improveaccess technology compatibilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by pre-configuring the mobile device with a resource list containing access technology configurations of available PLMNs before the device needs to select a network. This allows the device to perform compatibility checks in advance and only scan PLMNs that match its supported access technologies, avoiding wasteful scanning of incompatible networks and thereby reducing power consumption while maintaining reliable network selection

AI summary

A public land mobile network (PLMN) selection procedure may be generated that, when implemented, disables at least one resource of a particular mobile device to prevent a scan of particular ones of PLMNS that exhibit supported access technologies, and/or supported frequency bands of supported access technologies, incompatible with a preferred operation of the particular mobile terminal.
