Terminal Apparatus Dynamic Base Station Selection in Heterogeneous Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to efficiently switch between base stations or add/delete connections based on application-specific communication conditions in heterogeneous networks, as prior art does not adequately address the need for selecting a suitable base station for ongoing communication.
Innovation Solution
A terminal apparatus and communication system that receive connection-destination candidate information from base stations and select a new base station based on user application requirements, allowing for seamless switching, addition, or deletion of connections by transmitting control messages and measuring wireless communication qualities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a terminal apparatus selects a base station based on initial connection requirements, then the initial connection can be established, but the system cannot switch connection destinations or add/delete connections during ongoing communication
Solution Approach 1:
The patent implements dynamic connection destination selection by enabling the terminal apparatus to receive CDC notification control messages during ongoing communication and switch connection destinations based on changing application requirements. The system transitions from static initial connection selection to dynamic multi-phase selection, allowing connection destinations to be added, switched, or deleted during communication without system reconfiguration.
2Adaptability or versatility
If a terminal apparatus uses a fixed base station connection, then connection stability is maintained, but the system cannot adapt to different application-specific communication conditions
Solution Approach 1:
The patent segments the base station selection process into distinct phases: initial connection selection, intermediate connection destination switching, and connection destination addition/deletion. Each phase handles specific application requirements independently, allowing the system to maintain stable connections for ongoing applications while enabling flexible reselection for new or changing applications without compromising overall communication reliability.
3Ease of operation
If multiple base stations are available in a heterogeneous network, then communication flexibility increases, but the terminal cannot properly select the suitable base station for specific applications
Solution Approach 1:
The patent implements feedback mechanisms where the terminal apparatus continuously monitors application requirements and base station characteristics, receiving CDC notification control messages that provide information about suitable connection destinations. The system uses this feedback to dynamically adjust connection selections, ensuring that the terminal can properly match applications with appropriate base stations while simplifying the selection process through automated decision-making based on received information.

AI summary
To allow for selection of a connection-destination suitable for an application when switching from one connection-destination to another, or adding or deleting a connection-destination, a base station apparatus is configured to generate connection-destination candidate information on base station apparatuses as connection-destination candidates connectable to a terminal apparatus, and transmit to the terminal apparatus a connection-destination candidate notification control message including the connection-destination candidate information, and the terminal apparatus selects a new base station apparatus to be used as a new connection-destination based on the connection-destination candidate information and a communication condition required by a user application section, the user application section being configured to perform information processing required by a user concurrently with performing wireless communication.
