US 2010/0064056 A1 · COMMUNICATION SYSTEM AND METHOD

Abstract

A communication system includes a computer terminal and a server. The computer terminal includes a command control module and a response detecting module. The server includes a response control module. The command control module is configured for sending a command to the server. The response control module is configured for receiving the command, calculating a command check reference value according to the received command using a first formula, and sending a response to the response detecting module. The response detecting module is configured for calculating a response check reference value according to the response using a second formula. If the response check reference value is not equal to the response checksum bits value, the command control module resends the command corresponding to the received command to the server.

Dependent claims

A communication system, comprising:

a computer terminal comprising a command control module and a response detecting module;
and
a server comprising a response control module;
wherein the command control module is configured for sending a command to the server;
the response control module is configured for receiving the command and calculating a command check reference value using a first formula, determining if the command check reference value is equal to a command checksum bits value of the command, and sending a response to the response detecting module based on the compared result;
the response detecting module is configured for calculating a response check reference value according to the response using a second formula;
upon a condition that the response check reference value is not equal to a response checksum bits value of the received response, the command control module resends the command corresponding to the received command to the server.

A computer-readable medium having stored thereon instructions that, when executed by a computer, cause the computer to perform a method, the method comprising:

sending a command from a computer terminal to a server;
receiving the command;
calculating a command check reference value according to the received command using a first formula;
determining if the command check reference value is equal to a value of command checksum bits of the command;
upon a condition that the command check reference value is not equal to the value of the command checksum bits of the command, discarding the received command;
upon a condition that the command check reference value is equal to the value of the command checksum bits of the command, sending a response to the computer terminal;
calculating a response check reference value of the received response using a second formula;
determining if the response check reference value is equal to a value of response checksum bits of the received response;
upon a condition that the response check reference value is not equal to the value of the response checksum bits, discarding the received response, and resending a command corresponding to the received command to the server.
