HiGA Gateway Protocol Translation for IMS Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Second type terminal devices are unable to exchange control information with a first type service providing server due to differences in control protocols, preventing the execution of services with application-specific attributes.
Innovation Solution
A communication system with a gateway apparatus that includes service-specific mapping devices to translate first type control data from the server into second type control data for terminal devices, enabling the execution of services by processing the service-specific mapping devices to exchange first type control data with the server and second type control data with terminal devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard terminal devices are used, then device complexity is reduced and ease of manufacture is improved, but the ability to exchange control information with first type service providing servers is lost
Solution Approach 1:
The patent introduces a gateway apparatus as an intermediary component between standard terminal devices and first type service providing servers. The gateway contains service-specific mapping devices that translate first type control data into second type control data compatible with standard terminals, enabling communication without requiring the terminals themselves to be complex or adaptable.
2Adaptability or versatility
If service-specific mapping devices are added to the gateway, then adaptability is improved and control information exchange is enabled, but device complexity increases
Solution Approach 1:
The gateway apparatus is segmented into distinct functional components: service-specific mapping devices that handle protocol translation and a core gateway function that manages communication. This segmentation allows the mapping functionality to be added without fundamentally redesigning the entire gateway system.
3Adaptability or versatility
If first type control data is translated to second type control data, then compatibility with standard terminals is improved, but information loss may occur
Solution Approach 1:
The service-specific mapping devices perform parameter changes by translating control data between different protocols (first type and second type). The mapping process transforms the control information into a different format that is compatible with standard terminals while preserving the essential service control functionality.

AI summary
The present invention relates to a communication system (SYS), a gateway apparatus (HiGA) and a method for allowing services of a first type provided by a communication server (IMS-S) to be provided to terminal devices (T1, T2, . . . Tn . . . TN) of a home network (CPN) independent of the fact whether the terminal devices are of a first type or a second type (IMS-based or non-IMS-based). The gateway apparatus (HiGA) comprises one or more service-specific mapping applications (AS) for adapting the control plane (SIP) used between the second type terminal devices (T2) to the control plane (HTTP) used between the gateway apparatus (HiGA) and the communication sever (IMS-S).
