Method and apparatus for interfacing among mobile terminal, base station and core network in mobile telecommunications system

Abstract

A method, apparatus and a computer readable record media storing instructions for executing the same method for interfacing among a hybrid type synchronous or asynchronous terminal to a core network in a next generation mobile telecommunications system. The hybrid type synchronous or asynchronous radio network determines the operating type of the core network when the core network has a connection thereto, and sends the determined core network operating type information and information related to the core network to the hybrid type synchronous or asynchronous terminal, thereby allowing the synchronous or asynchronous terminal to smoothly perform a data interfacing operation with the core network.

1 . A method for interfacing among a terminal, a radio network and a core network connected to the radio network, wherein the radio network has an asynchronous operating type, said method comprising the steps of: 
 a) at the terminal, receiving a message including a core network operating type information; and    b) at the terminal, recognizing the operating type of the core network on the basis of the core network operating type information contained in the message, to thereby operate according to the recognized operating type of the core network.    
   
   
       2 . A method for interfacing among a terminal, a radio network and a core network connected to the radio network, wherein the radio network has an asynchronous operating type, said method comprising the steps of: 
 a) at the terminal, receiving a message including a core network operating type information representing the operating type of the core network; and    b) at the terminal, recognizing the operating type of the core network on the basis of the core network operating type information contained in the message, to thereby operate according to the recognized operating type of the core network.    
   
   
       3 . A method for interfacing among a terminal, a radio network and a core network connected to the radio network, wherein the radio network has an asynchronous operating type, said method comprising the steps of: 
 transmitting a message including a core network operating type information to the terminal,    wherein the core network operating type information contained in the message is used to allow the terminal to operate according to the recognized operating type of the core network.    
   
   
       4 . A method for interfacing among a terminal, a radio network and a core network connected to the radio network, wherein the radio network has an asynchronous operating type, said method comprising the steps of: 
 transmitting a message including a core network operating type information representing the operating type of the core network,    wherein the core network operating type information contained in the message is used to allow the terminal to operate according to the recognized operating type of the core network.    
   
   
       5 . A mobile communication terminal interfaced with a radio network and a core network connected to the radio network, comprising: 
 a layered protocol structure including a synchronous call control part, a synchronous mobility management part, an asynchronous call control part, and an asynchronous mobility management part,    wherein the terminal receives a message including a core network operating type information representing an operating type of the core network, recognizes the operating type of the core network on the basis of the core network operating type information contained in the message, and activates the synchronous call control part and the synchronous mobility management part or the asynchronous call control part and the asynchronous mobility management part in response to the message, to thereby operate according to the recognized operating type of the core network.
