The present invention will now be described with reference to the accompanying drawings.

1 is a block circuit diagram of a radio selective call receiver according to a preferred embodiment of the present invention.

In Figure 1, a radio selective call receiver, which is preferably a pager, receives at the antenna 101 a select call signal from a base station (not shown) of the paging system to which the pager belongs. The select call signal is demodulated in the wireless unit 102, waveform shaped and converted into a digital signal. This digital signal is supplied to the decoder unit 103 and decoded here, and the select call signal contained in the digital signal is assigned to the pager and compared with the select call number recorded in the ID-ROM 104. If the selection call signal and the selection call number match, the decoder unit 103 transmits to the control unit 105 a detection signal of the selection call signal and a message signal included in the digital signal and subsequent to the selection call signal. In response to this detection signal, the control unit 105 stores the message signal in its internal memory and then operates the speaker driver 112 to drive the speaker 113 to notify the user of the pager by voice.

2A to 2E show preferred examples of the signal format of the radio select call signal. As shown in Fig. 2A, the radio select call signal from the base station is composed of a number of time slots each comprising a preamble signal, an asynchronous signal SC, and two code words CW. Each code word CW consists of 31 bits, of which header 1 bit is the control bit and subsequent 21 bits are the message signal or ID signal. The remaining 10 bits are check bits. If the control bit is, for example, 0, the subsequent 21 bits represent an ID bit, and if 1, the subsequent 21 bits represent a message signal.

The message signal shown in Fig. 2C is composed of a message and a control code CC for message notification as shown in Fig. 2D. The message includes at least a numeric message such as a predetermined code and a telephone number corresponding to the predetermined message which is a preset message notification phrase. The control code CC includes at least a notification method selection code MC which designates a message notification method as a voice notification through the speaker 113 or a video notification through the liquid crystal display device 107. The control code CC may further include a predetermined designation code FC for distinguishing a predetermined code included in the message signal as shown in FIG. 2E. Multiple predetermined designation codes and multiple notification method selection codes are provided in a one-to-one correspondence. In this case, each code is represented by a number of bits. In addition, the predetermined message memory unit 107 preferentially stores the display format and the numeric message of a predetermined word corresponding to a predetermined code, and the preset voice memory unit 111 prefers digital data for the preset voice. I remember.

When it is necessary to confirm the message after the above-mentioned call notification, the user of the called party receiver operates the switch unit 106 to confirm the message. When the message confirmation operation is introduced, the control unit 105 decodes the message signal stored in the internal memory to determine whether the message is a predetermined message, a numeric message, or both. The control unit 105 also determines a notification method selection code provided in a one-to-one correspondence with the message to determine whether the message is a video message, a voice message or both.

If the message is a predetermined video message, the control unit 105 reads the predetermined message designated by the predetermined code stored in the internal memory from the predetermined memory unit 107, thereby causing the liquid crystal display driver 108 to operate. By driving, a predetermined message is displayed on the liquid crystal display 109. If the message is a predetermined voice message, the control unit 105 controls the preset voice memory unit 111 to output digital data for the preset voice matching the predetermined code, and controls the voice synthesizer unit 110. Control to synthesize preset voice. The voice synthesizer unit 110 drives the speaker driver 112 to output a preset voice synthesized from the speaker 113. When it is necessary to notify the message by audio and video, the control unit 105 drives both the liquid crystal display device 109 and the speaker 113. In addition, when the message is a numeric message, the control unit 105 also drives the liquid crystal display device 109 and the speaker 113 to notify the message reception as in the case of the predetermined message.

3 schematically illustrates a message notification method in the radio selective call receiver shown in FIG.

Referring to Fig. 3, an example of a message notification 012-34-5678 emergency call request provided by this receiver is shown. In this example, it should be noted that only notification D2 for the current time indication such as AM 12:20 or the like is normally displayed on the liquid crystal display 109 during the time when the receiver is ready to receive a call. After the call notification is provided by the speaker 113, for example, the user of the receiver operates the switch unit 106 to put the speaker into the message acknowledgment operation state. The control unit 105 then causes the liquid crystal display device 109 to display the message memory number D3 12345, the numeric message D1 012-34-5678 and the stereotype D4 emergency of the internal memory corresponding to the call. Next, the control unit 105 causes the speaker 113 to notify by voice of the stereotype message S1 call request. This voice notification can be done simultaneously with the video notification.

FIG. 4 is an example of a control code included in the message signal, and FIG. 5 is a stereotype of stereotype memory unit 107 and stereotype voice memory unit 111 of the radio selective call receiver shown in FIG. An example is shown. Fig. 6 shows an example of the correspondence between the message signal to be notified and the message.

A message signal input to the calling telephone when the wireless selective calling receiver according to the present invention is called by the calling telephone will be described later with reference to FIGS. 4 to 6.

First, referring to Fig. 4, the control code of the message notification to be input from the calling telephone is made of 2 or 3 symbols and / or numbers. The symbol ## is a message end code indicating the end of the message, and * 00 is a shift-to-numeral code indicating that the signal following this message end code is a numeric message. 11 is a notification method selection code for selecting a notification method of a message preceding this symbol. The symbol * 11 is followed by a number. In other words, if * 111, display notification is executed; if * 112, voice notification is executed; if * 113, display notification and voice notification are executed at the same time; if * 114, display notification is executed and then voice notification is executed. * 22 is a shift-to-stereotype message code indicating that the signal following this symbol is a stereotype message. The shift-to-numeric code and the shift-to-stereotype-message code are message code types indicating the message type.

Referring to Fig. 5, stereotypes are arranged in a matrix of Y (3) and X (3). This matrix is stored in the stereotype memory unit 107 and the stereotype voice memory unit 111 as memory cells of the stereotype message. Stereotype code 11 goes, 12 urgently, 13 to office, 21 will go, 22 later, 23 to home, 31 is the call request, 32 is the tomorrow, and 33 is the client.

6, examples A to D of message signals are shown, each of which consists of a control code shown in FIG. 2, a stereotype code shown in FIG. 3, and a numeric message. The message signal consists of a message type code, a message, a notification method selection code, and a message end code arranged in the order of description. When the calling telephone transmits a plurality of messages, it repeatedly transmits a message type code, a message, and a notification method selection code.

In Example D, the message is an emergency call request in which an emergency is noticed visually and the call request is notified by voice.

In this case, the caller inputs a message type code followed by a message that determines whether the message is a stereotype or numeric message. Since the message in Example D is stereotype urgent, the message signal is * 2212. Next, the caller inputs the notification method selection code * 11, and then enters one of the numerals 1, 2, 3, and 4 indicating the notification method. In Example D, the emergency is indicated, so the additional message signal is * 111.

The caller then enters a second message via the calling telephone. In Example D, since the second message is a stereotype message call request to be notified by voice, the message signal * 2233 * 112 is further input. Finally, the message input is terminated by entering ## indicating the end of the message input. Thus, in Example D, the input is * 2212 * 111 * 2233 * 112 ##. In FIG. 6, a gap is provided between adjacent portions of the message signal for easy understanding, but in practice, such a gap is not provided.

Incidentally, in Example A, the correspondence relation between the message signal containing 12345 and the call request and the message signal is shown, and in Example B, the correspondence between the message and the message signal including 678910 and the call request notified by voice and video, respectively In Example C, a correspondence relationship between a message signal and a message including 12345 notified by voice and a call request notified by video and voice is shown.

As described, in the radio selective call receiver according to this embodiment, the voice notification which is advantageous in terms of instantaneous and recognition of message notification and the video notification which is advantageous in terms of confirmation reliability of message reception can be used simultaneously or in parallel. There is this. In the receiver of the present invention, since it is set by the caller of the simultaneous use condition of voice notification and video notification, there is a feature that annoying operation on the receiver side does not occur in selecting a message notification method.

If the number M of the notification method and the number N of the stereotype code are large, the selection error probability is increased in selecting the notification method selection code and the stereotype code while the caller inputs a message signal to the telephone. Even if there is a selection error, the caller does not realize that unless the caller communicates with the called receiver, this selection error is a big problem for a radio select call receiver that handles one-way communication, so that at least a selection error is possible. Need to be reduced.

In this embodiment, the number M of the message notification scheme is four and the number N of the stereotype message is nine. If the stereotypes for each message notification method are categorized, the number P of the stereotype code becomes M × N in this embodiment, 4 × 9 = 36, and thus the caller's operation in inputting the message signal. The burden is very large. However, in the receiver of the present invention in which control codes related to stereotype selection and notification method selection are set separately as stereotype code and notification method selection code, the total number Q of control codes becomes (M + N), and M 2 And N 2 is PQ. Therefore, in the receiver of the present invention, the total number Q of the stereotype message and notification method selection codes can be minimized, so that the error probability of the caller can be minimized when these codes are selected. In addition, in the case where it is necessary to notify the very same message in multiple notification schemes, the caller's input operation is simpler since only one stereotype code exists.

As described in detail, the radio selective call receiver according to the present invention is a control code for notifying a selection call signal having a selection call number that matches the selection call number of the wireless selection call receiver, a message following the selection call signal, and a message. A receiver unit for receiving and decoding a radio selection call signal including the configured message signal, a voice notification unit for notifying a message by voice, a video notification unit for notifying a message as a video, and a decoded notification method selection code. A message notification method determination unit which selects one of a voice notification unit and a video notification unit on the basis and a notification control unit for notifying a message decoded by the selected notification unit, wherein the control code includes the voice notification unit and the video. Write down the notification method selection code that designates one of the notification units. Also, it is because the user of the change operation of the receiver need to reduce the user's burden in selecting the message notification system to change any of the message notification unit to another by including.

In addition, according to the present invention, it is possible to simultaneously use or simultaneously use the audio notification advantageous in terms of instantaneousness and recognition of message notification and the video notification advantageous in confirming reliability of message reception.

According to the present invention, the control code related to stereotype selection and notification method selection is set as a stereotype code and a notification method selection code when the message includes a stereotype. Therefore, when the number of stereotypes and the number of notification schemes is large, the total number of control codes can be reduced, thereby minimizing the possibility of error in setting up the stereotype message by the caller.

Although the present invention has been described with reference to specific embodiments only, those skilled in the art may recognize that various variations and modifications are possible, and thus all such variations and modifications are considered to be within the spirit and scope of the invention. It should be noted that
