Abstract

본 발명은 광역망 서비스가 가능한 광역서비스 기능을 갖는 무선 호출 수신기 및 그 수신방법에 관한 것으로, 본 발명의 무선 호출 수신기는 사용자와의 운용 데이터를 주고받는 인터페이스 수단(5, 6, 7, 8)과, RF 신호를 수신하는 안테나(9)와, 상기한 안테나(9)를 통해 수신된 RF 신호를 증폭한 후 POCSAG 코드 신호 형태의 2진 디지털 신호로 변환시켜주는 RF단(1)과, ID와 운용에 필요한 데이타가 저장되는 메모리(3)와, 상기한 RF단(1)에 연결되어 수신된 POCSAG 코드 신호로부터 동기 신호를 검출하여 동기 검출 신호를 발생하며 수신된 어드레스 코드워드 중 개인 ID가 상기한 메모리(3)에 저장된 개인 ID와 일치할 경우 ID 일치 신호를 발생하는 디코더(2)와, 상기한 동기 검출 신호에 응답하여 RF단(1)으로부터 입력되는 POCSAG 코드 신호로부터 어드레스 코드워드 중 지역 ID가 사용자의 지역 ID와 일치하는지를 판별하여 이를 기억시키고 상기한 ID 일치 신호에 응답하여 부저(5)나 진동장치(6) 중 어느 하나를 구동함과 동시에 상기한 디코더(2)로부터 인가된 수신 메시지 데이터를 LCD(8)를 통해 표시해 주는 제어수단(4)으로 구성된다.The present invention relates to a radio call receiver having a wide area service function capable of wide area network service, and a method of receiving the same. The radio call receiver according to the present invention provides interface means for exchanging operational data with a user (5, 6, 7, 8). And an antenna (9) for receiving an RF signal, an RF stage (1) for amplifying the RF signal received through the antenna (9) and converting it into a binary digital signal in the form of a POCSAG code signal, and an ID. And a memory (3) for storing data necessary for operation and the RF stage (1) connected to the RF stage (1) to detect a synchronization signal from the received POCSAG code signal to generate a synchronization detection signal, the personal ID of the received address codeword The decoder 2 generates an ID matching signal when the personal ID stored in the memory 3 matches and the POCSAG code signal input from the RF stage 1 in response to the synchronization detection signal. G Determining whether the station ID coincides with the user's area ID and storing it, and in response to the ID match signal, the buzzer 5 or the vibrator 6 is driven and applied from the decoder 2 at the same time. Control means 4 for displaying the received message data via the LCD 8;

상기한 바와 같이 구성된 본 발명은 소프트웨어적인 방법을 이용하므로 임의의 ID를 구별해 낼 수 있어, 광역망 서비스에 이용할 수 있으며, 본 발명의 CPU에는 ID 판별 기능만 부여하고 기타 데이터 처리는 디코더를 이용하므로 디코더보다 상대적으로 많은 전력을 소모하는 CPU에 의한 전력 소모를 방지할 수 있으며, CPU의 과도한 부담을 줄일 수 있는 효과를 제공한다.Since the present invention configured as described above uses a software method, any ID can be distinguished and can be used for a wide area network service. The CPU of the present invention is provided with only an ID discrimination function, and other data processing uses a decoder. Therefore, it is possible to prevent power consumption by the CPU, which consumes more power than the decoder, and to reduce the excessive burden on the CPU.

Claims

POCSAG code after amplifying the RF means received through the interface means (5, 6, 7, 8), the antenna (9) receiving the RF signal, and the antenna (9). The RF stage 1 converts the signal into a binary digital signal, the memory 3 storing ID and data necessary for operation, and the POCSAG code signal connected to the RF stage 1 for synchronization. A decoder 2 that detects a signal to generate a synchronization detection signal Sync.-det, and generates an ID matching signal when the personal ID of the received address codewords matches the personal ID stored in the memory 3; From the POCSAG code signal input from the RF terminal 1 in response to the synchronization detection signal, it is determined whether the area ID among the address codewords matches the area ID of the user and stored therein. Interface means (5, 6, 7 Control means (4) for driving any one of an alarm sound mode or a vibration mode and displaying received message data applied from the decoder (2) through the interface means (5, 6, 7, 8). Wireless call receiver having a wide area service function, characterized in that consisting of.

After the CPU starts to operate, the decoder detects the presence of a synchronization signal (Sync.-deta) at the decoder based on the POCSAG signal output from the RF terminal through the antenna. Sync. -Det), and the CPU sends Sync. determining whether a signal is present and operating a timer (32), reading (32) bits of received data supplied from the RF stage (33), and whether the received data is an idle codeword or an address codeword. (34) and if the data received in the determining step 34 is an address codeword, comparing the area ID among the received address data with the area ID inputted to the user's radio call receiver. If the result of the comparison between the step 35 and the ID does not match, the process proceeds to the data receiving step and receives new received data again and repeats the above steps. Stopping the timer (35, 36) after storing and performing a personal ID reading process using a decoder and a synchronization and message data signal processing process (3). 8) A reception method of a radio call receiver having a wide area service function, characterized in that consisting of.
