Home Subscriber Server Network Type Information Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Application servers in mobile telecommunication systems lack real-time information about the radio access network type used by user devices, leading to challenges in managing services when network types change during service provision.
Innovation Solution
Implementing a system where a Home Subscriber Server (HSS) receives and stores connection information, including network types, and provides this information to application servers, enabling them to manage services based on updated network types without relying on user devices for this data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If application servers rely on user devices to provide radio access network type information, then device complexity is reduced, but information availability and service management capability deteriorate
Solution Approach 1:
The patent introduces the HSS as an intermediary component that collects, stores, and provides radio access network type information to application servers. The HSS acts as a central repository that mediates between the user device and application servers, eliminating the need for devices to directly provide this information while ensuring accurate and timely information availability throughout the network.
2Adaptability or versatility
If real-time network type information is provided to application servers, then service management adaptability improves, but information transmission overhead increases
Solution Approach 1:
The HSS proactively stores radio access network type information in advance, before application servers need to request it. This preliminary action allows servers to obtain information on-demand without triggering continuous information transmission, reducing overhead while maintaining real-time adaptability when needed.
Solution Approach 2:
The system implements a feedback mechanism where application servers can request current network type information from the HSS based on their service management needs. This on-demand feedback approach ensures servers have up-to-date information for adaptive service management without requiring continuous information push, thereby controlling transmission overhead.

AI summary
A device may receive connection information associated with a connection, between a user device and a network, used to provide an application service to the user device. The connection information may include information identifying a network type of the network. The connection information may include information identifying an access point name associated with the connection. The application service may be provided by a device associated with providing the application service to the user device. The device may store the connection information based on receiving the connection information. The device may determine that the connection information is to be provided to the device associated with providing the application service to the user device, and may provide the connection information to the device associated with the application service. The connection information may permit the application service to be provided based on the network type of the network.
