In addition, the CMailPlus system analyzes the received message, and if the received message is a telegraph code, the message is translated into Chinese delivery.
Another case corresponds to step 208-step 214.
And step 208, the ship located at the AOR sends the message to the cooperative ground station. Specifically, the SAC of the cooperative ground station and the cooperative ground station code are selected.
For example, the message format is as follows:
To：cmailplus@cmailplus.com
CC：test
text content description: the first action is the public address distributed to all clients by the Beijing ground station, and the second action is the address sent by the clients.
And step 210, communicating the IGW service by the cooperative ground station, and sending the message to the CMailPlus system.
Step 212-step 214, the CMailPlus system processes the mail content periodically or periodically. And the CMailPlus system extracts the delivery address, judges the type of the receiving user and sends the delivery address according to the type of the user. Specifically, if the user is a fax user, the user is sent to the land fax user through the fax service unit 450; if the user is an Email user, the user is sent to a land Email user through the mail service unit 420 of the CMailPlus system; if the user is the SMS user, the SMS user is sent to the SMS user through the short message service unit 430; the land user can view the received message and the communication status in a Web manner through the Web service unit 440. In addition, the CMailPlus system analyzes the received message, and if the received message is a telegraph code, the message is translated into Chinese delivery.

And step 310, the Beijing maritime satellite ground station sends a receipt to the CMailPlus system.
Step 312, the CMailPlus system sends the receipt to the land user terminal.
Step 314-step 316, if the CMailPlus system does not receive the return receipt returned by the beijing maritime satellite ground station within the preset time threshold value, for example, 30 minutes, the CMailPlus system sends the message to the cooperative ground station through the IGW service of the cooperative ground station, and the cooperative ground station sends the message to the ship located in the AOR through the international maritime satellite covering the AOR.
And step 318, the cooperative ground station sends a receipt to the CMailPlus system.
And step 320, the CMailPlus system sends the receipt to the land user terminal.
And 322-324, if the called ship is located at the AOR and the state is normal, the CMailPlus system sends the message to the cooperative ground station through the IGW service of the cooperative ground station, and the cooperative ground station sends the message to the ship located in the AOR through the international maritime satellite covering the AOR.
Step 326, the cooperative ground station sends a receipt to the CMailPlus system.
Step 328, the CMailPlus system sends the receipt to the land user terminal.
