First, the CPU 7 outputs a control signal to the ID-ROM 5, outputs the stored data, and sets the frame register 47 and the address registers 48 and 54.
Further, when receiving a radio signal or the like for rewriting the ID code, the frame data and the address data which are set by the content of the radio signal and are newly stored in the ID-ROM 5 are output to the decoder unit 4 via the CPU 7, respectively. It is set in the register 50 and the address register 51. As a result, the frame register 47 contains the frame number of the frame used for calling the entire group of several pagers including the pager 1, that is, "3", and the address register 48 relates to the frame register 47. In the frame, an address to be called by only the pager 1 is set in the address register 54, and an address when the whole group is called in the frame related to the frame register 47 is set in the address register 51 according to the radio signal content. , A new address stored in the ID-ROM 5 is set, and a frame number related to the address of the address register 51 is set in the frame register 50.

After the above operations, the CPU 7 outputs a control signal to the BS control circuit 53 when an incoming call arrives, and the BS control circuit 53 starts the preamble search operation in response to this. On the other hand, the preamble signal is 18 times at a time.
Since the signal is continuously sent for the word time, when the receiving unit 3 is in the ON state (starting state), the preamble signal passes through the antenna 2 and the receiving unit 3 as a bit string and is a bit synchronization circuit of the decoder unit 4. 41 is input. Then, the preamble signal corresponds to the bit synchronization circuit 41.
Is synchronized with the circuit operation timing, and is output to the bit counter 45 and the word counter 46 via the sync code detection circuit 44. Based on the timing information input to the bit counter 45 and the word counter 46, BS
A control signal is output to the control circuit 53, the preamble search operation is stopped, and the synchronous code search operation is performed.

That is, every time 1 bit is input to the synchronization code detection circuit 44, which is sequentially inputting the bit string from the bit synchronization circuit 41, the input and the 31 bits previously sent are combined. Then, it is checked in 32 bit units whether the predetermined sync code pattern is obtained. When the sync code detection circuit 44 detects the sync code (preamble signal), the sync code detection circuit 44
The detection signal from resets the bit counter 45 and the word counter 46. Word synchronization is established by the above operation.

At the timing of the frame number "3", the address code word is received, and the address is transmitted from the bit synchronization circuit 41 to the BCH correction circuit 4
2, the BCH error correction process is performed, and the corrected data is given to the address comparison circuits 49 and 55. Further, at this timing, the frame register 47
A control signal is output from the CPU 7 to the address register 48 and the address register 48, which is controlled by the frame register 47, and the set address data is sent to the address comparison circuit 49 as a bit string. Is output.

Then, in the address comparison circuits 49 and 55, when the address received from the BCH correction circuit 42 is sent, the address is compared with the address assigned to the pager 1, and both are compared. It is judged whether or not it is done. At this time, when the address comparison circuit 49 or 55 detects that the addresses match, a detection signal is output from the address comparison circuit 49 or 55 to the BS control circuit 53 and the address message decoder via an OR gate (not shown). It The BS control circuit 53
Receiving this detection signal, the power supply of the receiving unit 3 is maintained in the ON state, and the reception is continued.

Next, the receiving process executed by the CPU 7 when the control data for rewriting the frame data and the address data is received will be described with reference to the flowcharts shown in FIGS.

First, the CPU 7 waits for reception (step S1), and when the call detection signal accompanying the reception is input from the decoder section 4 (step S2), the reception section 3 is made to continuously perform reception demodulation. Then, a control signal is output to the BS control circuit 53 to set the reception mode (step S
3). If the call detection signal is not received here, it returns to the reception standby state again.

When the reception mode is set, the CPU 7
Captures the received data following this calling signal (step S4). When the acquisition of the received data is completed (step S5), the reception mode end signal is output to the decoder unit 4, the BS control circuit 53 is instructed to the BS mode of the reception unit 3, and the main body of the pager 1 according to the content of the received data. Function control is performed (step S6). If the received data does not include the frame data and the control data for rewriting the address data stored in the ID-ROM 5 of the main body of the pager 1 (step S7), the received data is stored and displayed. (Step S8), when the data rewriting operation of the decoder unit 4 by the control data for rewriting the frame data and the address data is not interrupted or completed (Step S9), the reception standby state is returned again. (Step S1).

If the received data includes the control data for rewriting the frame data and the address data stored in the ID-ROM 5 of the main body of the pager 1 (step S7), the CPU 7 causes the receiving unit 7 Is B
The period in which the S state is set is the frame number data (frame number “3” in this embodiment) and the word counter 4
Data regarding driving of the receiver 3 in the pager 1 such as synchronization timing data is fetched from step 6 (step S10), and the ID-ROM 5 is read according to the received control data.
Is rewritten (step S11). Then, the time required for writing and resetting to the decoder unit 4 is calculated from the control data and compared with the data relating to the driving of the receiving unit 3 to determine the write period in the BS state or in the BS state as shown in FIG. Set (Step S1
2). Then, the writing to the decoder unit 4 is started according to the set writing period (step S13).
When a call detection signal is received during writing to the decoder unit 4 during this BS period (step S14), the rewriting operation is interrupted (step S15), and the process returns to the reception mode set (step S3).

When the call detection signal is not received during the writing to the decoder unit 4 during the BS period (step S14) and the data rewriting is completed according to the control data (step S16), the call is received again. The process returns to the standby state (step S1). When the data rewriting is not completed (step S16), the data rewriting is continued (step S17) and the process returns to the call detection signal reception determination process (step S14).

As described above, in the pager 1 of this embodiment, when the call detection signal of itself is received, the ID-ROM
When it is determined that the control information for rewriting the setting contents of the frame data and the address data stored in No. 5 is included, the time required for rewriting the control information is calculated, and the drive period of the receiving unit 3 The writing period is set in the taken non-driving period, and the ID-ROM is set according to the received control information.
Since the setting contents of 5 are rewritten, if a call detection signal is received during the rewriting, the rewriting can be interrupted and the reception mode can be immediately entered, and continuous reception can be performed without losing synchronization. It can be performed.

Further, in the pager 1 of the present embodiment, the frame register (second frame register) 50 in which the frame data and the address data which are rewritten by the setting contents included in the received control information are set in the decoder section 50. , The address register (second address register) 51 is provided.

Can be sent. As a result, it is possible to save the labor of transmitting control information on the transmitting side to a plurality of receiving devices that receive a common service in the same frame.

In the present embodiment, the setting contents contained in the received control signal set the respective data in the frame register 50 of the second frame and the address register 51 of the second address. Not limited to this, for example, the setting content may set only the data of the address register 54 of the second address of the first frame.
