Satellite Service Gateway Protocol Translation for Session Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in seamlessly integrating satellite networks with wireless devices and service providers due to differences in protocols and bandwidth requirements, leading to inefficiencies in session establishment and data transmission.
Innovation Solution
A service gateway within the satellite network translates lightweight wireless device trigger messages into compatible protocols like SIP or SS7, supplements mandatory data, and manages codec transcoding to facilitate seamless communication between wireless devices and service providers, including mobile operators and OTT service providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If lightweight protocols are used for satellite communication, then bandwidth efficiency is improved, but compatibility with service providers using standard protocols deteriorates
Solution Approach 1:
The service gateway acts as an intermediary between the wireless device using lightweight protocols and the service provider using standard protocols. It receives trigger messages from the wireless device, supplements them with mandatory data, translates them into standard protocols (SIP/SS7), and forwards them to the service provider, enabling seamless communication without requiring changes to either endpoint
Solution Approach 2:
The service gateway dynamically changes protocol parameters by transforming messages from one protocol format to another. It modifies message structures, adds required fields, and adapts data formats to match the service provider's protocol requirements while maintaining the original lightweight protocol's efficiency benefits
2Adaptability or versatility
If protocol translation and data supplementation are performed, then session establishment compatibility is improved, but processing complexity increases
Solution Approach 1:
The service gateway performs preliminary actions by maintaining pre-configured protocol translation rules and mandatory data templates for different service providers. This allows it to quickly supplement and translate messages without complex real-time decision-making, reducing processing complexity while maintaining high compatibility
3Reliability
If mandatory data is supplemented in trigger messages, then session establishment success rate is improved, but message processing time increases
Solution Approach 1:
The service gateway pre-configures mandatory data templates and validation rules for different protocol types and service providers. When a trigger message arrives, it quickly matches the message type to the appropriate template and supplements the required data without complex real-time analysis, minimizing processing time while ensuring high success rates
Solution Approach 2:
The system implements automated self-service mechanisms where the service gateway autonomously identifies missing mandatory data, retrieves it from pre-configured sources, and supplements messages without human intervention. This automation reduces both processing time and the potential for errors

AI summary
Apparatuses, methods, and systems for managing an interface of a satellite network between a wireless device and a service provider are disclosed. One method includes receiving through a satellite link, by a service gateway of the satellite network, a wireless device trigger message from the wireless device, wherein the satellite network includes a base station and a satellite core network, and performing, by the service gateway of the satellite network, session establishment of the wireless device with the service provider when receiving the wireless device trigger message, including modifying the wireless device trigger message to include additional data required by the service provider.
