Abstract

PURPOSE:To surely execute a call by executing the transmission by containing a specific code, in the case of executing an emergency call, and sounding continuously a calling sound until a user of a receiving side executes a stop operation. CONSTITUTION:In the case of an emergency call, when a receiving signal containing a U-code for showing its fact in a message is received from a decoder 4 to a CPU1, it is set in a RAM7, and stored in a U-code flag area. Subsequently, a continuous notice flag is set, a receiving notice is started by a loudspeaker 11 and an LED9, and even after a prescribed time elapses, a call is executed continuously until a reset switch is operated from a key input part 6. When the operation of the reset switch is confirmed, the call is stopped, and also, a processing for displaying the message on a display part 13 is started. In such a way, the emergency call can be recognized surely even if the other party of the call is in a separated place.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD OF THE INVENTION The present invention relates to paging receivers.

[0002]

2. Description of the Related Art A conventional paging receiver is provided with a plurality of addresses, and even if a silent mode that does not generate a ringing tone is selected when receiving at a specific address among them. There were those that could make a so-called priority call that generated a ringing tone.
This priority call is provided when it is necessary to make an emergency call to the carrier. On the other hand, paging receivers are generally provided with an auto reset function, including those of the type to which a priority call function is added, so that the ringing tone is not continued for a predetermined time or longer. Therefore, even if the ringing tone is generated by the above-mentioned priority call, the ringing tone generation is stopped after a predetermined time by the automatic reset function. For this reason, if the carrier puts the paging receiver in a bag etc. and leaves it in the car, and there is a priority call while leaving the car, and the generation of ringing tone is stopped by auto reset. Means that the carrier cannot recognize that there is an emergency call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the drawings. Configuration FIG. 1 shows a circuit configuration of an embodiment of the present invention. That is, each circuit section is connected to the CPU 1 as a center. The CPU 1 is a circuit unit that controls each circuit unit. The receiving unit 3 is a circuit unit that demodulates a radio wave received by the antenna 2. The ID-ROM 5 is a circuit that stores the frames and addresses individually assigned to the paging receiver, and sends the stored frames and addresses under the control of the decoder unit 4 to the decoder unit 4. is there. The decoder unit 4 collates the reception signal demodulated by the reception unit 3 with the data from the ID-ROM 5, and when the reception signal is transmitted to itself, sends it to the CPU 1 and After that, a control signal is sent to the receiving unit 3 and the receiving unit 3 is operated only at the timing when there is a transmission to itself.

The key input section 6 is a circuit section which is provided with various switches and which sends a corresponding key input signal to the CPU 1 when any one of them is operated. That is, the key input unit 6 has a mode changeover switch S _{M for} switching the mode between a ringing mode in which a ringing tone is generated when a call is received and a silent mode in which the ringing tone is not generated.
A reset switch S _R that is operated when stopping the generation of a ringing tone, and a read switch that is operated when sequentially displaying past reception messages stored in the _{RAM 7} described below on the display unit 13 described below. S _{Y and the} like are provided. The RAM 7 has a configuration described later and is a circuit for storing past received messages and the like.

The LED driver 8 is a circuit which receives a control signal from the CPU 1 and drives the LED 9. LED9
Is an LED which is driven by the LED driver 8 and blinks or lights to notify the reception. Speaker driver 10 is C
It is a circuit that receives a control signal from the PU 1 and drives the speaker 11. The speaker 11 is a speaker that is driven by the speaker driver 10 to generate a ringing tone.

The display buffer 12 is a buffer memory in which display data sent from the CPU 1 is set.
The display unit 13 is a circuit unit that includes a liquid crystal display panel and digitally displays the display data set in the display buffer 12.

FIG. 2 shows the configuration of the RAM 7 described above. The buffer register BR is connected from the decoder unit 4 to C.
The received data sent to PU1 is a register that is temporarily set. The pointer P is a register for designating each row of the reception information memory CM by the row address given to them. The mode flag MF is a flag that designates a mode, and is a flag that is set in the sounding mode and is lowered in the silent mode. The notification flag A is a flag that is set when reception notification is performed by the LED 9 or the like. The display flag D is displayed on the display unit 13.
This is a flag that is set when a received message or the like is displayed on. In this embodiment, even if an emergency call is received and then reception notification is continuously performed for a certain period of time, if the reset switch S _R is not operated during that period, the ringing tone continues at a certain period thereafter. However, the continuation notification flag L is a flag that is set when the ringing tone continues. The timer T ₁ is a timer used for measuring a general call notification time or a message display time so that each of them is a constant time, and the timer T ₂ is a continuation of the ringing sound at the above-mentioned constant cycle. It is a timer used for measuring a fixed period in the generation.

The reception information memory CM is a memory section which is composed of a large number of rows starting from the row address 1 and stores the reception information relating to one reception in each row. Also, the reception information memory C
Each row of M includes call type information related to the reception (for example, information indicating which address is called in a receiver having two types of addresses, and an address code word in a call using a POCSAG code). A call type information area CA that stores function bit information), a message information area MA that stores a message related to its reception, a reception related to an emergency call, and a U code (for example, P
It includes a U code flag area UA in which a U code flag is set when the 4 bit code “1011” used in the OCSAG code is included.

[0011] Operation Hereinafter, the incoming call processing operation of the present embodiment constructed in as described above will be described based on the flowcharts of FIGS.

(B) When there is an emergency call First, the case where an emergency call including the above-mentioned U code is transmitted in the message will be described. The received signal is
It is sent from the decoder unit 4 to the CPU 1. At this time, the call type information and message information therein are stored in the RAM 7
To the buffer register BR (step S
1). Then, it is confirmed that there is a U code in the message (step S2), and then the message or the like received this time is stored in an unstored line in the reception information memory CM (step S3). In this case, the line to be stored is designated by the pointer P, and the call category information area CA of that line is designated.
In the call type information, the message is stored in the message information area MA, and 1 is stored in the U code flag area UA. Then, in step S4, the continuous notification flag L
Check if is set up. That is, prior to the reception of the emergency call this time, there is another call, and it is checked whether or not the other call was an emergency call. When the continuation notification flag L is not set and the above case is not the case, the continuation notification flag L is set (step S5), the notification flag A is set, and the timer T ₁ starts measuring a predetermined time (step S6). ). Then, regardless of the mode, reception notification by the speaker 11 and the LED 9 is started (step S7).

After the processing of step S7 is completed, it is further determined whether another call is received (step S8). When another call is received, step S7 is performed.
Returning to step 1, the same operation as above is performed, but when another call is not received, whether the reset switch S _R has been operated, that is, the reception notification informs the carrier of the paging receiver that this time. reception recognized and the determining whether operating the reset switch S _R (step S9), and whether the operation of the reset switch S _R is when not made, the timer T ₁ is being accidentally measuring a predetermined time When it is checked (step S10) and the measurement has not yet been completed, the process returns to step S8.

For example, if the reset switch S _R is operated before the predetermined time is measured by the timer T ₁ , it is detected in step S9 and the reception information memory C is detected.
Of M, the U code flag in the U code flag area UA of the line in which the received message etc. of this time is stored is lowered (step S12), the notification flag A is lowered, and the reception notification by the speaker 11 and the LED 9 is stopped (step S12). S22), and proceeds to step S23 in FIG. Then, in step S23, the display flag D is set and the timer T
The elapsed time of a certain time is measured by ₁ and step S24
Then, the display process of displaying the received message and the like of this time on the display unit 13 is started.

Next, in step S25, it is determined whether another call is received after that. If it is received, the process returns to step S1 and the same operation as described above is repeated, but another call is not received. When the reset switch S
_It is checked whether or not the operation of _R or the measurement of a constant time by the timer T ₁ has been performed (steps S26 and S27), and thereafter, the operations of steps S25 to S27 are repeated. When the reset switch S _R is operated, the display flag D is lowered and the display operation on the display unit 13 is also stopped (step S2).
8) Wait for receipt of next call.

On the other hand, when the reset switch S _R is not operated while the process of steps S8 to S10 of FIG. 3 is repeated and the timer T ₁ measures the elapse of a certain time, the steps S10 to S11 are continued. Proceed to the notification process. When it is detected in step S4 that the continuous notification flag L has already been set (that is, when there is a preceding emergency call before the current emergency call and there is a current emergency call during the notification). ) Is also the above step S
The process proceeds to the continuous notification process of 11.

FIG. 5 is a flow chart showing the continuation notification process in detail. That is, in step S30, to measure a predetermined period by the timer T _2, and drives the speaker 11 to start the continuous call for very short time generate a ringing tone for respective periods, but to wait for the operation of the reset switch S _R (Step S32) During this waiting, when another call is received, this is detected in step S31, and the process returns to step S1 as described above to perform the subsequent processes. That is, when there is no other call and the reset switch S _R is not operated, the continuous call is continued. And
When the reset switch S _R is operated, the process proceeds from step S32 to step S33, the display flag D is set, the timer T ₁ starts the time measurement, and the message relating to the emergency call this time is displayed on the display unit 13. Is started (step S34). Then, the U code flag in the U code flag area UA of the row of the reception information memory CM in which the received message and the like of this time is stored is lowered (step S35), and further, in another row of the reception information memory CM. It is checked whether or not the U code flag area UA has a U code flag that has not been unloaded (step S36).
In this case, if there is a U code flag that has not been unloaded, the process directly proceeds to step S38, but if there is no U code flag that has not been unloaded, it is no longer necessary to perform continuous calling, so the continuous notification flag L is set. After lowering, the process proceeds to step S38. Then, in step S38,
After that, it is checked whether a call is received, and if it is, the process returns to step S1, but if it is not received, the operation of the reset switch S _R or the measurement of the predetermined display time by the timer T _{1 is} completed. Wait (step S3)
9, S41, S38, S39). If the reset switch S _R is operated during this standby, step S3
The process proceeds from step 9 to step S40, and it is determined whether or not the continuation notification flag L is set. When the continuation notification flag L is set, that is, the emergency call is received twice or more in succession and is still displayed. There is no emergency call message, and the above steps S36 to S38 are executed directly.
If it has proceeded, steps S40 to S3
Returning to step 3, the undisplayed emergency call message is displayed on the display unit 13 (steps S34 to S39).

[0018] On the other hand, when the reset switch S _R continue when the is operated broadcast flag L has been unloaded (step S39, S40), or the reset switch S _R is passed the display time without being operated this If it is detected (step S41), the display flag D is lowered to stop the display of the received message and the like on the display unit 13 (step S42), and the reception of the next call is awaited.

(B) When there is a general call Next, a case where there is a general call other than an emergency call, that is, a call in which a U code is not included in the messages sent at the same time will be described. Also in this case, the received data is temporarily stored in the buffer register BR (step S1), and it is confirmed in the next step S2 that the U code is not included in the message, and then the received data of this time is received information. It is stored in an unstored row in the memory CM (step S13). Next, it is checked whether or not the continuous notification flag L is set (that is, whether or not the current general call was during the reception notification of the previous emergency call) (step S14). When the continuous notification flag L is set, , Step S11, that is, the process proceeds to the flowchart of FIG. On the other hand, when the continuous notification flag L is not set and the current call is not in the above situation, the notification flag A is set and the time counting by the timer T ₁ is started (step S15).
Then, the process proceeds to next step S16.

In step S16, the mode flag MF is used to check whether the sounding mode is currently set. If the sounding mode is set, in step S17 the speaker 11 is driven to start the generation of the ringing tone. Step S18
However, when it is detected in step S16 that the silent mode is set, the process directly proceeds from step S16.
It proceeds to step S18. Then, in step S18, LE
The reception notification by D9 is started, and it is checked whether there is another call after that (step S19). If there is another call, the process returns to step S1. If not, the reset switch S _R is operated, or The system waits until the general reception notification time measured by the timer T ₁ has elapsed (steps S20, S21, S19, S20). When the reset switch S _R is operated during this standby, or when the timer T ₁ measures the elapse of the reception notification time without the operation, the notification flag A is lowered and the speaker 11 and the LED 9
To stop the reception notification (step S22).
After that, the process proceeds to steps S23 to S28 in FIG. 4 described above, and the received message or the like of this time is displayed on the display unit 13 for a predetermined display time or until the reset switch S _R is operated, and the reset switch S _R When there is an operation and when the display time has elapsed, the above display is stopped and the reception of the next call is waited. The present invention is not limited to the above embodiments, and various modifications can be applied without departing from the present invention.
