Mobile Object Network Selection via Remote Server Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for selecting a Public Land Mobile Network (PLMN) in mobile equipment, such as GSM modules, primarily rely on commercial agreements and signal strength, which can lead to inappropriate network selection, resulting in service unavailability, especially for applications requiring specific data transmissions like telemedicine, where TCP ports are critical, and do not account for network saturation or quality changes over time.
Innovation Solution
A method where a mobile object establishes a radio connection with a preferred PLMN, transmits signal and error information to a remote server, which verifies the connection and sends an acknowledgment, allowing the mobile object to automatically switch to another available network if validation fails, enabling autonomous network selection based on real-time conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic network selection is performed by the radio module based on commercial agreements and signal strength, then the network selection process is simplified and automated, but the service availability may be compromised due to inappropriate network selection
Solution Approach 1:
The patent implements a feedback mechanism where the mobile object transmits information about the selected network to a remote server, which validates whether the network is appropriate for the service. The server sends back validation results, and if the network is not appropriate, the mobile object automatically switches to another network. This closed-loop feedback system ensures service availability while maintaining automation.
Solution Approach 2:
The system performs preliminary validation of network suitability before committing to service operations. The mobile object proactively transmits network identification information to the server for validation, and the server pre-approves or rejects the network selection before the service is fully established, preventing service disruption.
2Reliability
If the mobile object continuously monitors and switches between networks to maintain optimal connection, then service availability is improved, but the complexity of the network selection process increases
Solution Approach 1:
The patent introduces a remote server as an intermediary that handles the complex validation logic. Instead of embedding complex decision-making algorithms in the mobile object, the system uses a centralized server to validate network suitability based on service requirements, commercial agreements, and network conditions. This distributes complexity from the mobile device to the network infrastructure.
3Reliability
If manual network selection is implemented to ensure appropriate network choice, then service availability is maintained, but the ease of operation is reduced
Solution Approach 1:
The system enables self-service by automatically performing network validation and switching without user intervention. The mobile object autonomously transmits network information to the server, receives validation results, and automatically switches networks if needed. This maintains service availability while preserving ease of operation through full automation.
4Measurement precision
If the mobile object transmits network information to a remote server for validation, then network selection accuracy is improved, but the communication overhead increases
Solution Approach 1:
The system performs partial validation by transmitting only essential network identification information to the server, rather than complete network state data. This provides sufficient accuracy for network selection while minimizing communication overhead and energy consumption. The server uses this partial information to make validation decisions based on pre-configured service requirements.

AI summary
Title: Method of establishing a connection between a mobile communicating object and a remote server. The present invention relates to a method of establishing a connection between a mobile communicating object and a remote server, by way of a mobile communication network where the communicating object has a list encompassing a determined number of preferred mobile communication networks with which the object can be made to connect. Said method comprises a first step where said communicating object establishes a radio connection with one of the networks available so as to transmit a first series of audit information (such as quality of the signal, error rate, base station cell identifier) to the remote server, a step of verification by said server of the data received and, in the event of anomaly, of engagement of a procedure for modifying the selection of the mobile communication network to which said mobile object is connected.
