Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for interconnecting different wireless communication networks are costly and time-consuming, requiring custom-designed gateways and standardization efforts, which hinder seamless communication when mobile stations migrate between incompatible networks.
Innovation Solution
A data interface interconnection gateway (DIIGW) that uses standardized air interface technologies to determine the location of mobile stations and establish virtual mobile stations, allowing communication between different wireless communication networks without the need for custom gateways or major infrastructure changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If custom-designed gateways are developed to interconnect different wireless communication networks, then communication compatibility between networks is improved, but development cost and time increase significantly
Solution Approach 1:
The patent applies universality by making the mobile station itself multi-functional, capable of operating in multiple wireless communication networks (e.g., both TETRA and GSM). Instead of requiring separate gateways for each network pair, the mobile station is designed with multiple air interface protocols, allowing it to register and communicate across different networks directly, thereby eliminating the need for complex custom gateways.
Solution Approach 2:
The patent uses the mobile station as an intermediary between different wireless networks. Rather than introducing external gateway infrastructure to mediate communication, the mobile station itself acts as the mediator by maintaining compatibility with multiple networks and facilitating its own registration and communication across network boundaries.
2Adaptability or versatility
If standardization efforts are undertaken to enable network interconnection, then interoperability between networks is improved, but implementation time and resource requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the mobile station with multiple air interface protocols and registration capabilities before deployment. The mobile station is designed in advance to support multiple networks (TETRA, GSM, etc.), eliminating the need for time-consuming standardization and gateway implementation efforts after deployment.
Solution Approach 2:
The patent changes the key parameter of mobile station capability from single-network support to multi-network support. By modifying the mobile station's inherent parameters (supported protocols, registration procedures), the system achieves interoperability without requiring external standardization processes or gateway infrastructure.
3Adaptability or versatility
If mobile stations are designed to operate in multiple networks, then migration capability is improved, but device complexity increases
Solution Approach 1:
The patent applies dynamics by making the mobile station's network operation dynamic rather than static. The mobile station can dynamically select which network to register with based on availability and compatibility, switching between TETRA, GSM, or other networks as needed. This dynamic capability enables migration without requiring complex fixed infrastructure.

AI summary
A data interface interconnection gateway (DIIGW 160) is provided that interconnects to different wireless communication networks (120-1, 120-2). The DIIGW implements methods for determining the network location of a mobile station (111-1) from among the different networks. The DIIGW communicates data link messages with standardized air interface protocols using a data service that implements an acknowledgement mechanism. The data service can be one of: a short data service (SDS), a TErrestrial Trunked RAdio (TETRA) high speed data service (TEDS), a TETRA packet data service, a short message service (SMS), general packet radio service (GPRS), a text messaging service or a wireless data link service. The DIIGW also implements at least one virtual mobile station (161) that corresponds to a real mobile station that has migrated to a visited wireless communication network, and can allow its corresponding real mobile station to communicate with its home wireless communication network.
