Service Platform for Flexible Message Distribution in Communication Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks are limited in their ability to broadcast and distribute various types of messages across different application servers and carriers, as existing configurations primarily focus on emergency information distribution and lack flexibility for diverse message content.
Innovation Solution
A communication system with a service platform positioned between network operator devices and application servers, which transmits distribution data and policies to network operator devices, enabling the broadcasting of different message types to multiple communication devices based on specific distribution policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network configuration is designed to distribute emergency information using CBS and ETWS, then emergency notification capability is improved, but the system cannot distribute various types of messages from multiple application servers
Solution Approach 1:
The system segments the message distribution function by introducing a service platform that separates emergency message distribution (handled by network operator device using CBS/ETWS) from general message distribution (handled by service platform routing to multiple application servers). This allows each segment to specialize while maintaining overall system versatility.
Solution Approach 2:
The service platform acts as an intermediary between application servers and the network operator device. It receives distribution requests from multiple application servers, determines appropriate distribution policies, and routes messages accordingly - enabling both emergency and non-emergency message distribution without compromising either function.
2Speed
If the network uses a fixed configuration for emergency message distribution, then emergency response speed is improved, but the network cannot adapt to distribute diverse message types from different carriers and application servers
Solution Approach 1:
The system implements dynamic message distribution by introducing a service platform that can adaptively route different message types through different paths. Emergency messages are rapidly distributed via CBS/ETWS through the network operator device, while other message types are routed through the service platform to appropriate application servers, allowing the system to dynamically adjust based on message content and urgency.
Solution Approach 2:
The service platform provides universal message distribution capability that handles both emergency and non-emergency messages. It can receive messages from multiple carriers and application servers, determine appropriate distribution policies, and route them to the network operator device or directly to target devices, making the system multi-functional without sacrificing emergency response speed.
3Device complexity
If the system is designed to handle only emergency information distribution, then system simplicity is improved, but it cannot support various types of messages from multiple application servers
Solution Approach 1:
The service platform serves as an intermediary layer that adds versatility without significantly increasing overall system complexity. It handles the complex logic of routing different message types from multiple application servers through appropriate distribution policies, while the network operator device maintains its relatively simple emergency message distribution function using established CBS/ETWS protocols.
