Circuit connection restoration method and program for restoring connection in short time

A connection link restoration method for a first information communication apparatus, comprising:

• providing a host computer;
• providing a communications module in communication with the host computer, performing;
• communicating data through a data transmission link;
• detecting a disconnection of the data transmission link;
• analyzing a reason for the disconnection of the data transmission link;
• determining whether or not to reconnect the disconnected data transmission link on the basis of the analysis of the disconnection reason;
• generating a reconnection command signal if the disconnected data transmission link should be reconnected;
• and
• generating a forced link disconnection command signal if the disconnected data transmission link should not be reconnected.

A connection link restoration method for a first information communication apparatus including a host computer and a communications module having a control unit, the communications module performing the method which comprises:

• performing radio communication by transferring a radio transmission signal;
• detecting disconnection of a radio transmission link for the radio transmission signal;
• analyzing, in the control unit, a reason for the disconnection of the radio transmission link;
• determining whether or not to reconnect the disconnected radio transmission link on the basis of the analysis of the disconnection reason;
• generating a reconnection command signal if the disconnected radio transmission link should be reconnected;
• and,
• generating a forced link disconnection command signal if the disconnected radio transmission link should not be reconnected.

A connection link restoration means, comprising:

• means for performing radio communication;
• means for detecting disconnection of a radio transmission link for a radio transmission signal, means for analyzing a reason for the disconnection of the radio transmission link,
• means for determining whether or not to reconnect the disconnected radio transmission link on the basis of the analysis of the disconnection reason,
• means for generating a reconnection command signal if the disconnected radio transmission link should be reconnected;
• and
• means for generating a forced link disconnection command signal if the disconnected radio transmission link should not be reconnected.

A communications system, comprising:

• a first information communication apparatus being in communication with a second information communication apparatus;
• the first information communication apparatus having a host computer and a communications module interfaced with the host computer;
• and
• the communications module having a control unit which determines a reason for a failure of communications between the first information communication apparatus and the second information communication apparatus,
• wherein a link disconnection signal is not sent to the host computer when there is a failure of communications between the first information communication apparatus and the second information communication apparatus.

A data communications system, comprising:

• a first information communication apparatus having a host computer and a communications module, the communications module having a control unit and a connection restoration circuit unit;
• and
• the information communication apparatus performing data communication through a data communications link;
• the control unit analyzing whether or not to reconnect data communications link when the data communications link has been disconnected based on a disconnection reason and inhibits a link disconnection signal from being communicated to the host computer;
• and
• the control unit generates a reconnection command signal if the data communications link should be reconnected and a forced link disconnection signal if the disconnected signal should not be reconnected.
