ABSTRACT:
In a method of establishing callback communication between first and second terminals via a relay station, the first terminal sends a callback request for establishing the callback communication to the second terminal. The method comprises the steps of: (1) establishing first connection between the first terminal and the relay station; (2) sending the callback request from the first terminal to the relay station; (3) establishing second connection between the second terminal and the relay station with the first connection being kept established in response to a request from the second terminal; and (4) linking the first connection with the second connection in order to establish the callback communication between the first and second terminals. Further, a relay station performing the method is also provided. This method dispenses with any identifier for identifying the first terminal on performing the callback.
