Message processing method, device, system and recording medium

A message processing method, comprising the steps of:

• generating a unique receive ID to identify the reception of a receive message when said receive message to which a unique transmit ID is added by a sender is received;
• registering said receive message into a storage while adding said generated receive ID to said receive message;
• extracting a transmit ID given by the sender from a receive message to which a receive ID identical with ID added to a transmit message is added of receive messages to be registered in said storage when said transmit message provided with said ID identical with said receive ID registered in the storage is transmitted;
• and
• transmitting said transmit message while adding said extracted transmit ID to said transmit message.

A message processing method, comprising the steps of:

• transmitting a transmit message to a second message processing device while adding a unique transmit ID to identify the transmission of a transmit message to said transmit message, and registering the correspondence between said transmit message and said transmit ID into a first storage, when, said transmit message is transmitted, by using a first message processing device;
• and
• generating a unique receive ID to identify the reception of a receive message when said receive message is received from said first message processing device, registering said receive message into a second storage while adding said generated receive ID to said receive message, extracting a transmit ID given by said first message processing device from a receive message to which a receive ID identical with ID added to a transmit message by the user is added of receive messages to be registered in said second storage when said transmit message provided with said ID by the user is transmitted, and transmitting said transmit message to said first message processing device while adding said extracted transmit ID to said transmit message, by using said second message processing device;
• wherein said first message processing device judges that a receive message is related with a previously-transmitted transmit message when said receive message to which ID identical with a transmit ID registered in said first storage is added is received from said second message processing device.

A message processing device, comprising:

• a storage;
• a transmission-managing means for adding a unique transmit ID to identify the transmission of a transmit message to said transmit message, and for registering the correspondence between said transmit message and said transmit ID into said storage when said transmit message is transmitted;
• a message transmitter for transmitting a transmit message provided with a transmit ID by said transmission-managing means;
• and
• a transmission-related detector for judging that a receive message is related with a previously-transmitted transmit message when said receive message to which ID identical with a transmit ID registered in said storage is added is received.

A message processing device, comprising:

• a storage;
• a reception-managing means for generating a unique receive ID to identify the reception of a receive message when said receive message is received, and for registering the correspondence between said receive message and said generated receive ID into said storage;
• and
• a reception-related detector for judging that a transmit message is related with a previously-received receive message when said transmit message to which ID identical with a receive ID registered in said storage is added is transmitted.

A message processing device, comprising:

• a storage;
• a reception-managing means for generating a unique receive ID to identify the reception of a receive message when said receive message to which a unique transmit ID is added by a sender is received, and for registering said receive message into said storage while adding said generated receive ID to said receive message;
• an other's information adding means for extracting a transmit ID given by the sender from a receive message to which a receive ID identical with ID added to a transmit message is added of receive messages to be registered in said storage when said transmit message provided with said ID identical with said receive ID registered in the storage is transmitted, and for adding said extracted transmit ID to said transmit message;
• and
• a message transmitter for transmitting said transmit message provided with said transmit ID by said other's information adding means.

A message processing system, comprising:

• a first message processing device which comprises a first storage, a transmission-managing means for adding a unique transmit ID to identify the transmission of a transmit message to said transmit message and for registering the correspondence between said transmit message and said transmit ID into said first storage when said transmit message is transnitted. a message transmitter for transmitting a transmit message provided with a transmit ID by said transmission-managing means to a second message processing device, and a transmission-related detector for judging that a receive message is related with a previously-transmitted transmit message when said receive message to which ID identical with a transmit ID registered in said first storage is added is received from said second message processing device;
• and
• said second message processing device which comprises a second storage, a reception-managing means for generating a unique receive ID to identify the reception of a receive message when said receive message is received from said first message processing device. and for registering said receive message into said second storage while adding said generated receive ID to said receive message, an other's information adding means for extracting a transmit ID given by said first message processing device from a receive message to which a receive ID identical with ID added to a transmit message by the sender is added of receive messages to be registered in said second storage when said transmit message is transmitted and for adding said extracted transmit ID to said transmit message, and a message transmitter for transmitting said transmit messageprovided with said transmit ID by said other's information adding means to said first message processing device.

A mechanically-readable recording medium, which stores a a program to operate a computer for a first message processing device as a transmission-managing means for adding a unique transmit ID to identify the transmission of a transmit message to said transmit message and for registering the correspondence between said transmit message and said transmit ID into a first storage when said transmit message is transmitted, a message transmitter for transmitting a transmit message provided with a transmit ID by said transmission-managing means to a second message processing device, and a transmission-related detector for judging that a receive message is related with a previously-transmitted transmit message when said receive message to which ID identical with a transmit ID registered in said first storage is added is received from said second message processing device, and to operate a computer for said second message processing device as a reception-managing means for generating a unique receive ID to identify the reception of a receive message when said receive message is is received from said first message processing device, and for registering said receive message into a second storage while adding said generated receive ID to said receive message, an other's information adding means for extracting a transmit ID given by said first message processing device from a receive message to which a receive ID identical with ID added to a transmit message by the sender is added of receive messages to be registered in said second storage when said transmit message is transmitted and for adding said extracted transmit ID to said transmit message, and a message transmitter for transmitting said transmit message provided with said transmit ID by said other's information adding means to said first message processing device.
