Shared Operator Identifier for Cross-Border PMR Network Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current PMR networks based on standards like ITU-T E.212 struggle to recognize users across national borders for international missions, as IMSI identifiers are country-specific and do not support seamless transboundary communication.
Innovation Solution
A method for configuring user identification modules with a shared operator identifier for international organizations or missions, using a unique MCC code and MNC code that is not tied to a specific country or region, allowing recognition across national borders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If country-specific IMSI identifiers are used in PMR networks, then national network identification is precise and unique, but international mobility and cross-border recognition are prevented
Solution Approach 1:
The IMSI identifier is segmented into two functional parts: MCC (Mobile Country Code) for national identification and MNC (Mobile Network Code) for network identification. This segmentation allows the MCC to maintain country-specific precision while the MNC can be configured to enable international roaming and cross-border recognition, resolving the contradiction between precise national identification and international mobility.
Solution Approach 2:
The MNC field is designed to serve multiple functions: it identifies the home network within a country, enables international roaming partnerships, and supports cross-border PMR network operations. This multi-functionality allows the same identifier structure to work for both precise national identification and versatile international mobility.
2Reliability
If unique international IMSI identifiers are assigned to each user, then global uniqueness is achieved, but seamless transboundary communication for international missions is hindered
Solution Approach 1:
The MNC acts as an intermediary between the country-specific MCC and the user-specific MSIN. It provides a layer of abstraction that enables international roaming agreements and cross-border network operations while maintaining the unique identification of each user through the combination of MCC-MNC-MSIN, thus facilitating transboundary communication without compromising identifier uniqueness.
3Adaptability or versatility
If standard ITU-T E.212 identification systems are used, then compatibility with public mobile networks is maintained, but support for international PMR missions is limited
Solution Approach 1:
The identification module is designed to be universal, supporting both standard public mobile network operations and specialized PMR mission requirements. The same IMSI structure (MCC-MNC-MSIN) works for general mobile communication and for international PMR missions, with the MNC field configured to enable mission-specific network recognition and roaming capabilities.

AI summary
A method of configuring modules for identifying users of a telecommunication network able to cover a service area, each identification module including an identification code stored in the identification module, the identification code including: an operator identifier; a user identification number; the method includes assigning a same operator identifier to a plurality of modules for identifying users belonging to a same organization or international mission.
