A radio terminal corresponding to a first radio terminal associated with a
second radio terminal comprises following units. A first receiving unit
receives a first request issued from the second radio terminal. An
establishing unit establishes, in response to the first request, a radio
link with respect to the second radio terminal. A setting unit sets, on
the radio link, a connection with the second radio terminal. A detecting
unit detects an event in association with the second radio terminal. A
first transmitting unit transmits, to the second radio terminal via the
connection, a first request message representing that first service
information concerning the second radio terminal should be transmitted to
the first radio terminal, when the detecting unit detects the event.
