Abstract:
PURPOSE: A control station device of an IMT-2000 network is provided to receive many base stations in a control station, which is connected with an ATM(Asynchronous Transfer Mode) exchange according to a network type by an ATM user-internetwork or an ATM internetwork interfacing standard and performs a handover function, so as to increase efficiency of a system assembly. CONSTITUTION: An ATM(Asynchronous Transfer Mode) router(210) performs routing functions relating to various traffic and control data between each circuit(230-290). A control station controller(220) transceives control data as an ATM adaptation layer(AAL)5 type with base stations through the ATM router(210) and base station interfacing circuits(250-280), and transceives control data with an exchange station through the ATM router(210) and an exchange station interfacing circuit(230), then transceives control data with each circuit(230-290) through the ATM router(210) to control a control station. The exchange station interfacing circuit(230) receives the control data from the control station controller(220) through the ATM router(210) to perform an interfacing function with the exchange station, and transceives traffic data with a vocoder selector circuit(240). The vocoder selector circuit(240) receives the control data from the control station controller(220) to perform a selector function for a voice source coding and a handover relating to the traffic data, and transceives the traffic data with the base station interfacing circuits(250-280). The base station interfacing circuits(250-280) perform transceiving functions for the traffic data and the control data with the base stations, and transmit the control data to the control station controller(220), then transmit the traffic data to the vocoder selector circuit(240). An operation and maintenance(OM) device(290) collects OM information from each circuit(210-280) to process the OM information, and transmits the OM information to the control station controller(220) to perform a function relating to an OM.

Abstract:
PURPOSE: A method and system for global roaming between international mobile telecommunications-2000(IMT-2000) systems having mutually different standards is provided to add interworking functions like an interworking mobile switching center(IMSC) and an interworking authentication center(IAC), and to absorb/convert a difference between standards of the IMT-2000 systems, so as to easily support the global roaming. CONSTITUTION: If a mobile subscriber of an European Telecommunications Standards Institute(ETSI) system(22) performs roaming to a Telecommunications Industry Association/Electronics Industry Association(TIA/EIA) system(21), a mobile station(MS) performs an authentication algorithm for the subscriber, and an authentication result value is transmitted to a base station(BS). The BS transmits the authentication result value and information related to location registration to a mobile switching center(MSC). The MSC transmits the authentication result value to a visitor location register(VLR) in order to decide whether the subscriber is appropriate. The VLR transmits the authentication result value to a TIA-interworking location register(ILR). The TIA-ILR transmits the authentication result value to an ETSI-interworking authentication center(IAC) of the ETSI system(22). The ETSI-IAC performs an authentication algorithm, an authentication key, and an authentication procedure of the TIA/EIA system(21). The ETSI-IAC of the ETSI system(22) compares the a result value of the authentication algorithm with the authentication result value from the TIA-ILR, to decide whether the subscriber is appropriate. A decided result is transmitted to the TIA-ILR. The TIA-ILR transmits the authentication decision result to the VLR. The VLR transmits the authentication decision to the MSC.
Abstract:
PURPOSE: A method for certification in a mobile communications net by using a smart card is provided to prevent that an unqualified user uses the service and to prevent network exposure of secret information of the user by using the smart card in the mobile communications circumstance. CONSTITUTION: A method for certification in a mobile communications net by using a smart card includes a few stages. In the first stage the certifying center of network generates a public key and a secret key and stores them in DB of the certifying center when execution begins. In the second stage(41) the mobile subscriber registers service with own ID in the certifying center. In the third stage(42,43,44) the mobile subscriber puts own smart card into the mobile terminal and judges yes or no of network excess. In the fourth stage(45) network certifies information sent through the mobile terminal and the smart card and inspects if the mobile subscriber and the smart card holder are reasonable or not when the mobile subscriber tries network excess by putting own smart card into the mobile terminal. In the fifth stage(46,47,48) the mobile subscriber gets mobile service according to the result of inspecting and ends the mobile communications service and removes the card from the mobile terminal and then the identity certification and inspecting service using the smart card end.

Abstract:
PURPOSE: A data message modulating device is provided to improve power efficiency of a terminal by reducing a peak-to-average power ratio of a mobile communication system. CONSTITUTION: A data message modulating device comprises a coder(110) which codes a data message to be transferred to a base station to generate one or more of data parts. A central processing unit(180) is coupled to the coder, and receives a spread vector associated with the data parts from the coder. The unit(180) calculates one or more of code numbers related to the data parts, and calculates the spread vector and the code numbers. A code generator(120) has a spread code generator(121), a signature generator(122), and a scrambling code generator(123), and is coupled to the unit. The code generator(120) generates a spread code. A spreader(130) spreads a control part from the coder and the data parts using the spread code from the code generator(120). A pair of I and Q data are generated through a scrambler(140), a filter(150), a gain adjusting part(160), and an adder(170) which are coupled in serial.
