IMS Menu Server Personalizing Service Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in identifying and accessing available communication services on their terminals, as existing systems lack efficient methods to display and update service menus based on subscriber capabilities, leading to limited utilization of terminal functions and unsatisfied demands for diverse services.
Innovation Solution
A system and method where a menu server manages subscriber service capability information to provide personalized service menus, allowing terminals to authenticate and download updated service menus, ensuring users can easily access and select available services by comparing subscribed services with terminal capabilities and providing necessary client programs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a subscriber wants to receive a subscribed service, then the service can be provided to the user, but there is no efficient way for the user to find out which service is available through his terminal
Solution Approach 1:
A menu server is introduced as an intermediary component that stores service capability information and generates service menus. The menu server acts as a mediator between the service provider and the terminal, efficiently delivering service availability information to users based on their terminal capabilities and subscribed services, thereby resolving the information asymmetry problem.
Solution Approach 2:
The terminal is equipped with the ability to autonomously determine its own capability information and request appropriate service menus from the menu server. The terminal can self-identify its capabilities and automatically obtain the corresponding service menu without requiring manual configuration or intervention, improving ease of service discovery.
2Adaptability or versatility
If the terminal displays all available services, then users can access diverse services, but the terminal display utilization is reduced due to lack of personalized service presentation
Solution Approach 1:
Service menus are customized according to each terminal's specific capability information and the subscriber's service subscriptions. Instead of displaying all available services uniformly, the system presents locally optimized service lists tailored to each terminal's display capabilities, resolution, and supported features, thereby maximizing display utilization while maintaining service diversity.
Solution Approach 2:
The service menu is dynamically generated and updated based on the terminal's capability information and the subscriber's service subscriptions. The menu server can adaptively adjust the service presentation according to changes in terminal capabilities or subscribed services, ensuring optimal display utilization without sacrificing service versatility.
3Adaptability or versatility
If the terminal downloads service applications to implement subscribed services, then the services can be executed, but the process requires manual intervention and is not efficient
Solution Approach 1:
Service capability information and corresponding service menus are pre-configured and stored in the menu server before being requested by the terminal. When a terminal connects, the service menu is already prepared and can be quickly downloaded without requiring manual service application installation or configuration, significantly reducing service setup time while maintaining implementation versatility.

AI summary
A system and method for providing an Internet Protocol (IP)-based service in a communication system are provided. In an IP Multimedia Subsystem (IMS) communication system, a menu server generates a service object based on service capability information of a subscriber received from a service provider, and a terminal activates the service object received from the menu server so that the subscriber can easily use services. The user can select one of services from a service menu displayed on the terminal and immediately implement the selected service.
