Abstract:
A method for interfacing among a terminal, a radio network and a core network connected to the radio network in a mobile telecommunication system, wherein the radio network has a base station (BS) and each of the terminal and the radio network has a hybrid operating type being possible to be set as either a synchronous operating type or an asynchronous operating type, said method comprising the steps of:a) at the BS, determining an operating type of the core network and generating core network operating type information representing the operating type of the core network; b) at the BS, setting an operating type of the BS to the synchronous operating type or the asynchronous operating type on the basis of the core network operating type information; c) at the BS, providing the terminal with the core network operating type information and information related to the core network through a predetermined channel in a form of a message; d) extracting, at the terminal, the core network operating type information from a received message, the core network operating type information being inserted into a predetermined location of the message; e) recognizing, at the terminal, the operating type of the core network on the basis of the extracted core network operating type information; and f) at the terminal, setting an operating type of the terminal to the synchronous operating type or the asynchronous operating type on the basis of the recognized operating type of the core network.
