Description
본 발명은 듀얼밴드듀얼모드 단말기에서 SIM 카드 정보를 대상으로 과금하는 기술에 관한 것으로, 특히 CDMA와 WCDMA 모드에서 모두 통화하면서 SIM 카드 정보만을 이용하여 과금할 수 있도록 한 듀얼밴드듀얼모드 단말기의 과금 방법에 관한 것이다.The present invention relates to a technology for charging SIM card information in a dual band dual mode terminal, and in particular, a charging method of a dual band dual mode terminal capable of charging using only SIM card information while talking in both CDMA and WCDMA modes. It is about.
CDMA 폰의 호 처리를 설명하면, 단말기에 전원이 인가될 때 이이피롬(EEPROM)으로부터 필요한 시스템 정보(NAM: Number Assignment Module)를 읽어와 램(RAM)에 셋팅한 후 파일럿 채널, 동기 채널을 이용하여 시스템과 동기를 일치시키고 필요한 시스템 정보를 수신한다. In the call processing of a CDMA phone, when a terminal is powered on, it reads the required system information (NAM) from EEPROM, sets it in RAM, and then uses a pilot channel and a synchronization channel. To synchronize with the system and receive the necessary system information.
상기 CDMA 폰의 전체적인 호 처리 과정을 도 1을 참조하여 설명하면 다음과 같다.The overall call processing process of the CDMA phone will be described with reference to FIG.
단말기(MS: Mobile Station)에 전원이 공급되기 시작하는 초기화 상태에서, 단말기를 부팅시키고 파일럿 채널과 동기 채널을 수신한다. 그리고, 단말기가 모든 시스템 정보를 수신하여 정상동작을 완료한 후에는 페이징(paging) 채널을 계속 수신하는 아이들 상태에 놓이게 된다. 이후, 단말기가 시스템에 접속하기 위한 시스템 액세스 상태를 거친 후 통화중인 트래픽 상태에 놓이게 된다. In an initialization state in which power is supplied to a mobile station (MS), the terminal is booted and receives a pilot channel and a synchronization channel. After the terminal receives all the system information and completes the normal operation, the terminal is in an idle state for continuously receiving a paging channel. Thereafter, the terminal goes through a system access state for accessing the system and is placed in a busy traffic state.
한편, WCDMA 폰의 호 처리 과정은 단말기에서 필요한 정보를 SIM 카드에서 읽어오는 것을 제외하고 상기 CDMA 폰의 호 처리 과정과 동일하다.On the other hand, the call processing of the WCDMA phone is the same as the call processing of the CDMA phone except that information required by the terminal is read from the SIM card.
그런데, 종래의 기술을 이용하여 듀얼밴드듀얼모드(DBDM: Dual Band Dual Mode) 폰을 구성할 경우, WCDMA 모드에서는 SIM 카드에 의해 과금이 행해지는 반면, CDMA 모드에서는 기기의 EEPROM에 저장된 NAM 정보에 의해 과금이 행해지게 된다. 따라서, 폰을 교체할 경우 SIM 카드를 변경해야 할 뿐만 아니라 기기를 같이 변경해야 하는 불편함이 있고, 과금도 따로 처리하게 되므로 SIM 카드를 사용하는데 따른 본래의 이점도 없어지게 된다. 또한, 기기 등록시에는 CDMA 폰 번호도 기록되어야 하지만, 실제 사용자가 부여받는 번호는 WCDMA 폰 번호 하나 뿐이다. 따라서, 외부에서 CDMA 폰으로 전화를 걸 경우 사업자가 WCDMA 폰 번호에 대해 CDMA 폰 번호를 매칭시키기 위한 장치를 필요로 하는 문제점이 있었다. However, when configuring a dual band dual mode (DBDM) phone using the conventional technology, charging is performed by the SIM card in the WCDMA mode, while in the CDMA mode, the NAM information stored in the EEPROM of the device is used. Charging is done. Therefore, the replacement of the phone not only has to change the SIM card, but also the inconvenience of changing the device, and because the billing process separately, the original advantage of using the SIM card is also lost. In addition, the CDMA phone number should also be recorded when registering the device, but the actual user is assigned only one WCDMA phone number. Therefore, there is a problem that the operator needs a device for matching the CDMA phone number to the WCDMA phone number when making a call from a CDMA phone from the outside.
따라서, 본 발명의 목적은 CDMA와 WCDMA 모드에서 모두 통화하면서 SIM 카드 정보만을 이용하여 과금하는 듀얼밴드듀얼모드 단말기의 과금 방법을 제공함에 있다.Accordingly, an object of the present invention is to provide a charging method of a dual band dual mode terminal for charging using only SIM card information while talking in both CDMA and WCDMA modes.
본 발명에 의한 듀얼밴드듀얼모드 단말기의 과금 방법은, 폰이 초기화 수행 후 위치등록기에 WCDMA의 NAM 정보를 등록하면서 DBDM인 코드를 같이 알려주는 제1단계와; 위치등록기에서, 전송되어 온 SIM 카드 정보를 등록하는 제2단계와; 자신의 테이블에서 할당한 CDMA MIN 정보를 폰에 통보하는 제3단계와; 폰이 위치등록기로부터 전송되어 온 CDMA MIN 정보를 저장하여 통화에 사용하는 제4단계로 이루어지는 것으로, 이와 같은 본 발명의 과금 처리과정을 첨부한 도 2 및 도 3을 참조하여 상세히 설명하면 다음과 같다.The charging method of a dual band dual mode terminal according to the present invention includes a first step of informing a DBDM code together with a phone registering NAM information of WCDMA in a location register after performing initialization; Registering, at the location register, the transmitted SIM card information; A third step of notifying the phone of the CDMA MIN information allocated from its table; The phone is a fourth step of storing the CDMA MIN information transmitted from the location register to use the call, and will be described in detail with reference to FIGS. 2 and 3 attached to the billing process of the present invention as follows. .
통상적으로, 중요한 폰 정보를 램으로 로딩한 후 사용하게 되는데, 본 발명은 이 중에서 ESN(ESN: Electronic Serial Number)의 경우 수정이 불가능하지만, MIN(MIN: Mobile Identification Number)의 경우에는 수정이 가능하다는 것에 착안한 것이다. 폰이 초기화 수행 후 위치등록기(HLR)에 등록시 WCDMA의 NAM 정보를 등록하면서 기지국에서 더미 CDMA MIN을 할당해 주는 방식이다. 따라서, 통화 요금은 등록된 SIM 정보의 번호에만 할당하게 되므로, 기기의 모드에 상관없이 과금할 수 있게 된다. Typically, important phone information is loaded into RAM and used. In the present invention, the modification is not possible in the case of ESN (Electronic Serial Number), but in the case of MIN (MIN: Mobile Identification Number). I thought about it. When the phone registers with the location register (HLR) after initialization, the base station allocates the dummy CDMA MIN while registering the NAM information of the WCDMA. Therefore, since the call charge is assigned only to the registered SIM information number, the call charge can be charged regardless of the mode of the device.
본 발명이 적용되는 망의 구성은 기존의 망과 동일하며, 위치등록기 내부에 하기의 새로운 정보가 추가된다. 상기 위치등록기는 도 2와 같은 더미 MIN 정보를 가진 데이터베이스를 보유하고 있어야 하며, 그 데이터베이스는 룩업테이블로 구성되어 있어야 한다. The configuration of the network to which the present invention is applied is the same as the existing network, and the following new information is added to the location register. The location register must have a database with dummy MIN information as shown in FIG. 2, and the database must be configured with a lookup table.
사용자가 DBDM 폰을 휴대하고 서비스 지역에 진입하면, 상기 위치등록기에 등록을 요청하게 되는데, 이때, 폰이 DBDM인 코드를 같이 알려주면 그 위치등록기는 보내온 SIM 카드 정보를 등록하게 되며, 자신의 테이블에서 할당한 CDMA MIN 정보를 폰에 통보하게 된다. 따라서, 상기 폰은 위치등록기로부터 전송되어 온 CDMA MIN 정보를 저장한 후 이를 통화에 사용한다.When a user carries a DBDM phone and enters a service area, the user requests a registration to the location register. At this time, if the phone notifies the DBDM code, the location register registers the SIM card information sent thereto. The phone will notify the CDMA MIN information assigned by. Therefore, the phone stores the CDMA MIN information transmitted from the location register and uses it for the call.
이상에서 상세히 설명한 바와 같이 본 발명은 폰이 위치등록기에 등록시 WCDMA의 NAM 정보를 등록하면서 기지국에서 더미 CDMA MIN을 할당하여, 등록된 SIM 카드 정보의 번호를 대상으로 요금을 할당하게 함으로써, 기기와 모드에 상관없이 과금할 수 있는 효과가 있다. As described in detail above, the present invention provides a device and a mode by allocating a dummy CDMA MIN at a base station while allocating a charge to a number of registered SIM card information while registering a NAM information of WCDMA when the phone registers with a location register. Regardless of whether you can charge the effect.
또한, 사용자가 DBDM 폰 사용시 SIM 카드만 삽입하고도 별도의 등록절차 없이 두 모드로 전화 서비스가 가능하고, 하나의 번호로 모드에 관계없이 서비스가 가능한 이점이 있다. In addition, when a user uses a DBDM phone, even if only the SIM card is inserted, the phone service can be performed in two modes without a separate registration procedure.
