ABSTRACT:
When a connection is established between a client device and a server device, a first message requesting establishment of a downlink connection is transmitted from the client device to the server device, and a server device which has received the first message is caused to transmit to the client device a second message requesting establishment of an uplink connection. The client device which has received the second message is caused to transmit to the server device a third message acknowledging the second message and requesting establishment of the downlink connection. The server device which has received the third message is caused to establish the downlink connection based on the content of the third message.
