TVWS Database Query for Wireless Terminal Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless terminals face challenges in determining the availability and connecting to different access network technologies when moving between locations, as they need to identify and establish connections with various access networks efficiently, which is not effectively addressed by existing solutions.
Innovation Solution
A method and apparatus that utilize a TVWS database to store and provide information about connectivity capabilities and requirements for TVWS access networks, allowing wireless terminals to retrieve this information before attempting a connection, thereby optimizing network access and conserving battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless terminals attempt to connect to access networks without pre-retrieving connectivity information, then they can establish connections when available, but they waste battery power and time making unnecessary connection attempts
Solution Approach 1:
The patent implements preliminary action by having wireless terminals query a database for access network connectivity information before attempting to connect. The terminal sends a query message containing its location and access technology type, receives connectivity status information in advance, and only attempts connection when the database indicates availability. This pre-check mechanism eliminates wasted battery power from unsuccessful connection attempts while maintaining high connection establishment efficiency for available networks.
2Adaptability or versatility
If wireless terminals support multiple communication modes and move between locations, then they can access different network technologies, but they face difficulty determining which access networks are available without extensive searching
Solution Approach 1:
The patent introduces a database as an intermediary between wireless terminals and access networks. The database stores pre-collected connectivity information for multiple access network technologies at various locations and responds to terminal queries with availability status. This intermediary eliminates the need for terminals to perform extensive active searching or scanning across multiple communication modes, significantly reducing network discovery time while maintaining adaptability to different network technologies.
3Loss of information
If wireless terminals actively scan for access networks at each location, then they can discover available networks, but they consume excessive energy and time performing repeated scanning operations
Solution Approach 1:
The patent implements copying by having the database store copies of access network connectivity information that can be quickly retrieved and distributed to multiple terminals. Instead of terminals performing energy-intensive active scanning to discover network availability, they query the database for pre-collected connectivity status copies. This approach maintains accurate information about access network availability while dramatically reducing the energy consumption associated with repeated scanning operations.

AI summary
Example methods and apparatus to provide network capabilities for connecting to an access network are disclosed. A disclosed example method involves receiving a request at a first access network of a first network type. The request is addressed to a database and requests network connectivity information for connecting a wireless terminal to a second access network of a second network type different from the first network type. The example method also involves sending a response to the wireless terminal via the first access network. The response includes the network connectivity information for connecting the wireless terminal to the second access network.
