Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a selective call receiver having a message display function.

(Prior Art) In recent years, as a new type of selective calling system, a system has been proposed in which a call can be made by sound or light emission, and a message can be transmitted and displayed. In this type of system, for example, when a call request and a transmission message for an arbitrary selective call receiver are sent to a base station, the base station sends a message that encodes the individual number code of the selective call receiver and the transmission message. This selective calling signal is inserted into an empty calling word of the group to which the selective calling receiver belongs and is transmitted. Then, the selective calling receiver receives the selective calling signal and compares the individual number code with the individual number code of the subscriber's own machine, and if the two codes match, the subscriber is informed by a ringing sound or flashing that a call has occurred. At the same time, the message code is decoded and displayed on, for example, a liquid crystal display. If such a system is used, it is very convenient to be able to convey to the subscriber, for example, a contact telephone number or a caller's name as a message.

By the way, selective call receivers that use this type of system generally have a memory for storing messages, and even after the message display at the time of a call is automatically erased, it can be stored in the memory by operating the display switch. Memorized messages can be read out and displayed again.

Therefore, the subscriber can check the received message even if the subscriber is unable to check the message when the call occurs due to some reason, or even if the subscriber can check the message but wants to check it again.

(Problem to be Solved by the Invention) However, this type of conventional receiver stores only the message code in the memory, so when the message is later read out from the memory and redisplayed, the message is It was not possible to know when the message was received, which sometimes made it impossible to take an appropriate response.

The present invention has focused on this point, and aims to provide a selective calling receiver that allows the reception time of each message to be clearly known, and thereby allows an appropriate response to be taken at all times.

[Structure of the Invention] (Means for Solving the Problems) The present invention includes a timer and a message storage control means, and when a call occurs, the message storage control means clocks the received message code by the timer. The information is stored in the memory along with received time information.

(Function) As a result, when the message stored in the memory is read out and redisplayed on the display, the reception time of this message will be displayed at the same time, allowing the subscriber to know when the message code was received. This makes it possible to clearly know what has happened, and this allows appropriate responses to be taken at all times.

(Embodiment) FIG. 1 shows the configuration of a selective call receiver in an embodiment of the present invention. This selective call receiver first transmits a selective call signal sent from a base station (not shown) to an antenna 1.
After being received by a radio circuit 2 via a mixing circuit 3, the signal is mixed with a local oscillation signal generated from an oscillation circuit 4, frequency-converted, and then demodulated by a demodulation circuit 5. This demodulated selective calling signal is then introduced into the control circuit 6.

This control circuit 6 has a collation and decoding means 61 and a call display control means 62, and the collation and decoding means 61 stores in advance the individual number code in the selective call signal in the memory circuit 7. The number code is compared with the number code, and when both codes match, a sound signal is output from the call display control means 62 and supplied to the speaker via the drive circuit, thereby generating a sound. At the same time, the message code inserted in the selective call signal is decoded by the collation and decoding means 61, and the decoded message is sent to the display 10.
I am trying to supply and display it.

Incidentally, reference numeral 11 is a group of switches for stopping the sound and display of messages, and for selectively displaying stored messages.

By the way, the receiver of this embodiment has a memory 12 for storing messages and a clock circuit 13 for measuring time, and further includes message storage control means 63 and message display control means 64 as control means of the control circuit. It is equipped with Of these, the message storage control means 63 stores the received message code in the memory 1 every time a call occurs.
At the same time, the time of the clock circuit 13 is added to the message code as call time information and stored in the memory 12. Note that if the memory 12 can only store a maximum of six pairs of messages and call time information, for example, when the memory 12 is full, the newly received message code and its new message code will be stored instead of the oldest message code. and call time information. On the other hand, the message display control means 64 reads out the pair of message code and call time information stored in the memory 12 and displays it on the display 10 when the display switch is operated while the message is not displayed. be.

Next, the operation of the receiver configured as described above will be explained according to the control procedure of the control circuit 6. In the call standby state, the control circuit 6 performs step 2a, for example, as shown in FIG.
Then, in step 2b, operation monitoring of the display switch and arrival monitoring of a call to the own machine are repeatedly performed.

When a selective call signal is received in this state and a call to the own machine is detected, the control circuit 6 performs step 2.
At step 2c, the speaker 9 generates a ringing sound to notify the subscriber that a call has occurred, and at step 2d, the message code is decoded. Then, in step 2e, information representing the current time is input from the clock circuit 13 as call time information. In step 2f, it is determined whether the call that has just occurred from the received message is a re-arrival call or not, and then predetermined display and storage control are performed in accordance with the determination result. That is, if the content of the message just received is different from the content of any message already stored in the memory 12, it is determined that it is a new call and the process proceeds to step 2g.
Then, the received message and the calling time information are respectively displayed on the display 10. Then, in step 2h, the received message code and call time information are written into an empty area of the memory 12 or an area where the message with the oldest reception time is stored.

On the other hand, if there is a message already stored in the memory 12 that has the same content as the message just received, it is determined that the call has arrived again and the process moves to step 21. The call time information is displayed on the display 10 with a re-arrival mark attached. Then, in step 2j, only the call time information out of the message code and call time information stored in the memory 12 is rewritten. Thus, the message storage memory 12 stores the received message code as well as its calling time information.

When displaying and storing the message is finished, the control circuit 6 proceeds to step 2 and step 2.7? The operation of the stop switch is monitored and the message display time is monitored, and when the stop switch is pressed or a certain period of time has elapsed, the process moves to step 2m, where the generation of the sound and the display of the message are stopped, and the call is made. Return to standby state.

On the other hand, in the call standby state, the subscriber
When the display switch is operated to check the message stored in the display switch, the control circuit 6 detects the operation of the display switch in step 2a and thereafter shifts to the message display control mode. That is, as shown in FIG. 2(b), first, in step 2n, the message code and the calling time information are respectively read out from a predetermined area of the memory 12, and then in step 2n, the message code and the calling time information are respectively read out.
0, the message obtained by decoding this message code and the calling time are displayed on the display 10, respectively.

By visually checking this display 10, the subscriber can know the contents of the message as well as the time when the message was received. When the message and the reception time are displayed, the control circuit 6 monitors the operation of the stop switch and the progress of the display time in steps 2q and 2'', and monitors the operation of the display switch in step 2p. Then, when the stop switch is operated or the display switch is operated again before a certain period of time has elapsed, the process returns to step 2n, where the message code and call time information are retrieved from a different storage area of the memory 12. Read each and display on display 1.
Display it at 0. Similarly, each time the display switch is operated, the control circuit 6 selects a different storage area in the memory 12 and displays the message code and call time information on the display 1.
Store it as 0. Thus, the subscriber can check all the messages stored in the memory 12 and their ringing times by operating the display switch.

In this example, each time a call occurs,
Since the received message code is stored in the memory 12 together with the reception time information, when the message code stored in the memory 12 is redisplayed and the contents are confirmed, the subscriber can of course check the contents of the message. You can also know the time when this message was received. Therefore, more appropriate measures can be taken. Furthermore, in this embodiment, when storing the message code and reception time information in the memory 12, it is determined from the content of the received message whether or not it is a second call. Since only the reception time information of the message code and reception time information is updated, new information can always be stored without wasting memory.

Note that the present invention is not limited to the above embodiment.

For example, the message code and reception time information stored in the memory 12 are periodically read out while waiting for a call, and the elapsed time from the reception time is determined based on the reception time information. In some cases, it may be automatically deleted. In addition, the manner in which the reception time information is used, the control procedure and control content of the control circuit, the display form of the time information, etc. can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As described in detail above, the present invention includes a timer and a message storage control means, and when a call occurs, the message storage control means causes the received message code to be clocked by the timer. By storing reception time information in the memory, it is possible to clearly know the reception time of each message, thereby providing a selective calling receiver that can always respond appropriately. can.
