Common Service Device for Multi-Carrier Message Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network configurations, such as those disclosed in Patent Literature 1, are unable to broadcast and distribute various types of messages requested by multiple carriers, limiting their capability to handle different content distributions across multiple application servers.
Innovation Solution
A common service device connected to multiple distribution networks aggregates application servers, authenticates requests, and selects appropriate distribution networks for message broadcasting, enabling the transmission of broadcast distribution requests to ensure diverse message dissemination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a network configuration is designed to distribute emergency information using CBS and ETWS services, then disaster notification capability is improved, but the system cannot distribute various types of messages requested by multiple carriers and application servers
Solution Approach 1:
The common service device is designed to perform multiple functions: it authenticates application servers from different carriers, selects appropriate distribution networks based on message type and carrier, and manages both emergency information (CBS/ETWS) and general message distribution. This multi-functional design allows a single device to handle diverse messaging requirements while maintaining reliable emergency notification capabilities
Solution Approach 2:
The common service device acts as an intermediary between application servers and distribution networks. It receives distribution requests from multiple carriers' application servers, performs authentication, selects the appropriate distribution network, and forwards requests accordingly. This intermediary role enables the system to support multiple carriers and message types without compromising the reliability of emergency information distribution
2Reliability
If a specific flash report transmission station is used for message distribution, then emergency information distribution is achieved, but the system cannot handle messages requested by a plurality of different carriers
Solution Approach 1:
The common service device merges the functions of multiple flash report transmission stations into a single unified device. It consolidates authentication capabilities for multiple carriers, maintains connections to multiple distribution networks, and provides centralized message distribution. This merging allows the system to handle messages from multiple carriers while preserving the reliable emergency information distribution capability of the original flash report transmission station
3Productivity
If a broadcast distribution service is provided in a network managed by a carrier, then data distribution to communication devices is achieved, but the system lacks the capability to aggregate multiple application servers from different carriers
Solution Approach 1:
The common service device provides universal access points that can authenticate and process distribution requests from application servers belonging to different carriers. It maintains a unified interface for receiving distribution requests while supporting multiple carriers' application servers, thereby enabling efficient data distribution across the network without requiring separate infrastructure for each carrier

AI summary
An object of the invention is to provide a common service device cable of broadcast distribution of various types of messages. A common service device (20) according to the present invention aggregates a plurality of application servers (40) and is connected to a plurality of distribution networks (30). The common service device (20) includes: an authentication unit (21) that performs authentication for a first application server by using a distribution request message transmitted from a first application server included in the plurality of application servers (40) via a first interface commonly set among the plurality of application servers (40); and a communication unit (22) that selects a first distribution network for which broadcast distribution is requested from among the plurality of distribution networks (30) based on the distribution request message, and transmits a broadcast distribution request message to the selected first distribution network.
