Logical Channel Table for DH-CLF Interface Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of a defined logical interface between a Device Host (DH) and a Contactless Front End (CLF) complicates communication, especially when using different communication standards, leading to potential difficulties in establishing connections and increasing processing time due to unnecessary queries and association processes.
Innovation Solution
An information processing apparatus with a connection control unit that creates and updates table information to establish logical channels between processing units, allowing for communication through interfaces with different standards without specifying a corresponding logical channel, thereby omitting unnecessary queries and reducing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a unique specification different from HCI is used for the logical interface between DH and CLF, then implementation flexibility is improved, but communication difficulty increases due to managing different interface information
Solution Approach 1:
The patent introduces a correspondence table as an intermediary mechanism that bridges the DH and CLF interfaces. This table maps and associates the logical channels from different interface specifications (HCI and alternative specifications), enabling the system to manage multiple interface types uniformly. The correspondence table acts as a mediator that translates between different interface information management schemes, resolving the contradiction between implementation flexibility and communication ease.
2Adaptability or versatility
If logical channels are established with different communication standards, then adaptability is improved, but processing time increases due to unnecessary queries and association processes
Solution Approach 1:
The patent implements preliminary action by pre-establishing the correspondence table before actual communication occurs. This table is prepared in advance to store the association relationships between logical channels of different communication standards. When communication is needed, the system can directly query this pre-prepared table to find the corresponding logical channel, eliminating the need for time-consuming real-time queries and association processes, thus reducing processing time while maintaining multi-standard compatibility.

AI summary
An information processing apparatus including processing units and a connection control unit that controls the connections between the processing units, in which the connection control unit is provided with a table creation unit which, with respect to a first logical channel established with a processing unit, creates table information showing a correspondence between logical channels without designating a logical channel that corresponds to the first logical channel when there is no second logical channel established with another processing unit that corresponds to the first logical channel, a table storage unit that stores the table information created by the table creation unit, and a table update unit that updates the table information for the second logical channel that is stored in the table storage unit so as to configure the first logical channel as a logical channel that corresponds to the second logical channel when there is a second logical channel.
