Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a paging receiver which receives message information following its own calling number and displays the message information.

[Prior art and its problems]

Conventionally, as a method of calling a person carrying a paging receiver and transmitting a message including character information, a paging receiver is provided with a fixed phrase memory in which a fixed phrase message is stored, and a calling side makes a specific call from a touch-tone phone. There is a method of sending the number and the abbreviated code of the fixed phrase message suitable for the content of the message to be transmitted to the radio base station. The calling number and the abbreviated code sent to the wireless base station are sent as a wireless signal from the wireless base station to call. Then, the specific receiver corresponding to the calling number receives the message data including the abbreviated code following the calling number, sounds the ringing tone, and stores the received message data in the built-in memory.

The user of the above-mentioned receiver cannot know whether or not there is an emergency call only from the normal ring tone, and after confirming the message contents, if the call is an emergency call, the user is contacted.
However, there is a drawback that the message is not always confirmed immediately after the reception, and if the confirmation of the message by the user is delayed, the user cannot be contacted immediately.

Therefore, in order to inform whether or not there is an emergency call at the time of reception, for example, in a paging system using the POCSAG method, a method of notifying an emergency call using two function bits of an address code word, or one of message information is used. It is conceivable that the department adds data indicating that it is an emergency call and transmits it.

However, if the function bit is used for distinguishing an emergency call, the function bit cannot be used for identifying the four callers, and if a special code is added and transmitted, not only the input operation will increase but also the data operation will increase. It has a drawback that the transmission time becomes long.

[Purpose of device]

It is an object of the present invention to provide a paging receiver that can transmit the same message information as before without adding new data and notify the receiving side whether or not there is an emergency call.

[Key points of device]

According to the present invention, when the message information is received, a means for determining whether or not the fixed phrase shortening code in the received message information is a predetermined shortening code is provided, and the determining means determines that it is the predetermined shortening code. In this case, a call notification different from the usual one is made.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a block diagram showing a circuit configuration of a paging receiver of one embodiment. In the figure, the radio signal received from the antenna 1 is amplified, detected, and demodulated in the receiving unit 2, converted into digital data of “0” and “1”, and output to the decoder unit 3. The decoder unit 3 is a circuit for comparing whether or not the calling number composed of the data of "0" and "1" matches with its own calling number stored in the ID-ROM 4, and when the calling numbers match, it continues. The received data is output to the CPU 6, and when the calling numbers do not match, the receiving unit 2 is instructed to terminate the reception.

Although not shown in the figure, the switch group 5 is composed of a search key for searching a received message, a switch for stopping an alarm sound at the time of reception, etc., and these operation signals are output to the CPU 6.

The CPU 6 is a central processing unit that detects a key input from the switch group 5 and stores the received message in the message memory 7. When the received message is received from the decoder unit 3, the CPU 6 causes the alarm control unit 7 to receive the message. Notice. The sound control unit 7 receives an instruction from the CPU 6 and drives the speaker 8 to sound that there is a call. Fixed phrase memory 10 corresponding to the shortened code received at this time (described later)
When the call information (call notification control information) stored in is "1", that is, when an emergency call is meant, even if the sound mode switch is set to the silent mode, the CPU 6 controls the sound. The unit 7 is instructed to make a sound, and the speaker 8 makes a sound different from the normal call.

The fixed phrase memory 10 is a ROM that stores character codes of a plurality of fixed phrase messages and call information indicating whether or not the fixed phrase message is an emergency call. FIG. 2 is a diagram showing a part of the configuration of the fixed phrase memory 10, in which the character codes of the fixed phrase messages shown in FIG. “1” is stored as the call information in the memory units M ₃ and M ₄ of the message including the characters “Urgent”, for example, the fixed phrase messages corresponding to the abbreviated codes “03” and “04”, and “Urgent” is stored. “0” is stored as call information in the memory units M ₁ and M ₂ of the fixed phrase message that do not include the character “”.

The character generator 11 is a ROM that stores a character font corresponding to the character code of the fixed phrase memory 10. The display unit 12 is composed of a liquid crystal display or the like and includes a switch group 5
The received message stored in the message memory 9 is displayed by the operation of.

Further, the LED control unit 13 and the LED 14 are for displaying an incoming call by light, and the LED 13 is turned on by an instruction from the CPU 6.

Next, the processing operation at the time of reception of the embodiment having the above configuration will be described with reference to the flowchart of FIG. When the message is received, the message received in step S ₁ is stored in the head of the message memory 9. And step S ₂
In call information corresponding to the shortened code received is determined whether "1", to determine whether silent mode proceeds to step S ₃ If "0". If not silent mode proceeds to step S _4, After sounding a normal ring specified by the function bits, etc. described above, drives the LED13 of proceeds informing an incoming call in step S _5, directly to step if silent mode only the display of LED13 proceed to S ₅ in informing an incoming call. Further to end the display to process a message that there is an incoming call on the display unit 12 in the next step S _6.

On the other hand, when the call information of the fixed phrase memory 10 that matches the shortened code received in the determination of step S ₂ is “1”,
Its AutoText message is sounding that there was a call regardless of whether silent mode proceeds to step S ₄ it means an emergency call.

Therefore, when an abbreviated code of an emergency call phrase is received, for example, even if the silent mode is set by the sound mode switch, a ring tone is output to notify the user of the receiver that there is an emergency call. it can.

In the above embodiment, when the message of the emergency call is received, the ring tone is output even if the alarm mode switch is set to the silent mode. You may make it notify by a different vibration pattern. In addition to storing the call information corresponding to each abbreviated code, when the abbreviated code corresponding to the emergency call and the abbreviated code corresponding to the normal call are stored in different blocks and the abbreviated code is received by the receiver. The urgency of the call may be determined by determining which block the code is in.

[Effect of device]

According to the present invention, it is possible to determine whether the received message information is an emergency call or not by the fixed phrase shortening code included in the message information. Therefore, whether the call is a normal call as a part of the message information to be transmitted. Alternatively, it is not necessary to transmit information indicating whether the call is an emergency call, and both calls can be distinguished and informed without reducing the data transmission efficiency.
