Abstract:
The present disclosure relates to providing user information. In a method for requesting user information of an information requesting device in a mobile communication system, the method includes selecting a callee from a user, acquiring a user identifier (ID) of the selected callee, transmitting a user information request for the selected callee and the user ID to a relay server, evaluating whether an admission message is received from the relay server, and if the admission message is received, receiving user information from the relay server.

Abstract:
A clock synchronizing method in a multistage switch structure comprises providing a first reference clock signal to a first switch via a first clock recovery unit; providing a second reference clock signal to a second switch via a Phase Lock Loop (PLL); and providing a third reference clock signal to a third switch via a second clock recovery unit to synchronize first, second and third switches.
