Multimode Terminal Service Discovery via Network Indication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless multimode terminals face challenges with high power consumption due to frequent network scanning and user-unfriendliness when managing multiple radio technologies, limiting efficient access to local services in a city-scale environment.
Innovation Solution
A mechanism where a mobile network indicates available short-range wireless technologies to a multimode terminal, allowing it to selectively activate and search for compatible networks, compile a service list, and present it to the user, thereby reducing power consumption and simplifying access management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the terminal frequently scans for supported networks to detect alternative access technologies, then the terminal can discover available services, but power consumption increases significantly
Solution Approach 1:
The mobile network performs preliminary actions by indicating the availability of short-range wireless systems to the terminal before the terminal needs to scan. This allows the terminal to activate short-range radios only when necessary, rather than continuously scanning, thereby reducing power consumption while maintaining service discovery capability
Solution Approach 2:
The mobile network acts as an intermediary that provides information about available short-range wireless systems to the terminal. This intermediary role allows the terminal to make informed decisions about when to activate short-range radios, reducing unnecessary scanning and power consumption
2Adaptability or versatility
If the terminal integrates multiple radio technologies to provide diverse access options, then service accessibility is improved, but the complexity of operating different radio technologies increases
Solution Approach 1:
The terminal automatically performs service discovery and compilation of service lists based on indications from the mobile network, without requiring user intervention. The system serves itself by autonomously managing the complexity of multiple radio technologies while presenting simplified service information to the user
Solution Approach 2:
The mobile network serves as an intermediary that abstracts the complexity of multiple radio technologies from the user. By providing indications about available short-range systems and enabling automatic service discovery, the intermediary role simplifies the user interface while maintaining access to diverse technologies

AI summary
The invention relates to a method for discovering services for a wireless multimode terminal with a plurality of radio interfaces. In order to improve the efficiency of a wireless multimode terminal in terms of power consumption and user-friendliness, an indication is sent to a multimode terminal in the mobile network, the indication indicating that services may be locally available for the multimode terminal via at least one short-range wireless network. The indication is received in the multimode terminal, and information is collected, based on the indication, about services available via at least one short-range wireless network. Based on the information collected, a service list is then compiled, the list describing at least one service available locally in one or more short-range wireless networks.
