レゼンス情報の要求を行う（ｓ１，ｓ２）。First, the information requesting means 22 of the communication terminal 2-1.
Sends a request for presence information to the communication terminal 2-2 (s1, s2). At this time, if the communication terminal 2-2 is operating normally online, the presence information is sent to the communication terminal 2-2.
-1 is continuously transmitted during the expiration date (T1) of the request.
The information requesting means 22 of the communication terminal 2-1 continues to receive the presence information during the expiration date of the request (s3, s4),
When the request expiration date has passed, the communication terminal 2-2 is again requested for presence information (s1, s2).
