• a) making a request to establish a connection between the transmitting end apparatus and the receiving end apparatus;
• b) the free transmitting end application receiving a unique ID of the receiving end apparatus from the paid receiving end application;
• c) the free transmitting end application executing an internal inspection operation to determine if the unique ID exists in an exception list in the free transmitting end application;
• d) the free transmitting end application reading a flag in the paid receiving end application to execute an external inspection operation if the unique ID does not exist in the exception list;
• e) determining if the paid receiving end application supports an operating system used by the transmitting end apparatus according to the flag;
• f) the transmitting end apparatus and the receiving end apparatus establishing an unlimited connection when determines the paid receiving end application supporting the operating system used by the transmitting end apparatus via the flag;
• and
