Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective calling receiver, and more particularly to a radio selective calling receiver, in addition to editing a character string for each of a plurality of fixed phrases so that it is possible to recognize from whom a message is transmitted without looking at a display unit. The present invention relates to a radio selective calling receiver capable of changing a sound depending on the content of a message by being able to designate a sound.

[0002]

2. Description of the Related Art A radio selective call receiver compares a transmitted call number with its own call number stored in a storage means, checks a message, extracts a message accompanying the call number, and converts the message into characters. Display on the display means.

At the time of message retrieval, when a message is searched for when converted to a character and matches the character stored in the storage means, two digits of the character are numbers and the number stored in the storage means is In this case, the contents corresponding to the two-digit numeric characters are retrieved from the storage means in a database of kana characters, alphanumeric characters, illustration characters, etc., and displayed on the display means. Has recently been in service (Japanese Unexamined Patent Publication No. 3-232).
327).

[0004] In the above-mentioned fixed phrase service, fixed phrases that can be edited and registered by the holder of the radio selective call receiver are assigned in addition to the fixed phrases defined by the business operator. Thus, the holder can register desired kana characters, alphanumeric characters, illustrations, and the like.

[0005] Further, there is also provided a service in which the sound of a report at the time of reception can be set by the holder of the radio selective call receiver. A receiver having a plurality of call numbers is provided with a call number. There is also a service in which a sound can be set separately (see Japanese Patent Application Laid-Open No. 63-252029).

[0006]

As described above, according to the prior art, a message at the time of reception can only be sounded by the sound set by the holder, so that the caller can send a message to the holder at the time of notification. Sound cannot be specified.

In this case, if the caller has a plurality of call numbers and the caller selects and calls the call number, the tone can be designated. However, the service provided by the carrier who performs the transmission management reduces the number of telephone lines. At present, a service for providing a plurality of call numbers is not widely used because of the fear.

Further, since only the number of call numbers can be designated as a sound at the time of notification, a radio selective call receiver having only one call number must recognize the received message by looking at the display unit after all. Will not be.

An object of the present invention is to solve the above-mentioned problems,
An object of the present invention is to provide a service that can easily designate a plurality of sounds at the time of a report at an existing transmitting station without increasing the number of telephone lines.

[0010]

In order to achieve the above-mentioned object, according to the present invention, for a fixed-form sentence service which has already been turned into a service, a notification sound at the time of reception is stored in a storage element in addition to characters for each fixed-form sentence. When this message is included in the message, the character string stored in the storage element and the contents of the notification sound designation at the time of reception are taken out, and the display unit Is displayed with the stored contents (character string), and the sound at the time of notification is performed with the specified contents.

[0011] Further, when the holder of the radio selective call receiver edits the fixed phrase, the display characters are not registered, and only the notification sound at the time of reception can be stored in the storage element. When the fixed message stored in the above message is included in the message, a control is provided so that nothing is displayed on the display unit, so that the display unit does not display anything, The feature is that only can be specified.

[0012]

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a radio selective calling receiver according to the present invention.

In this radio selective calling receiver 100,
The radio carrier modulated by the selective calling number and the following message signal on the transmitting side is received by the antenna 101 as a selective calling signal, amplified by the radio section 102, and then demodulated into a baseband signal.

The call number detector 103 performs error correction and word cutout in accordance with a predetermined signal format (for example, POCSAG system), extracts a selected call number from the selected call signal, and EEPRO the selected call number.
Call number of own machine and control unit 1 stored in M108
Match at 04. If they match,
After the message signal following the selected calling number in the selected calling signal is taken out and subjected to error correction, it is stored in the RAM 107 via the control unit 104.

The CPU 105 performs message processing according to the program shown in the flowchart of FIG.

(Clock).

Next, the radio selective calling receiver 1 shown in FIG.
The selective call signal received by 00 will be described.

FIG. 2A shows a format of a selective call signal received by the radio selective call receiver 100 shown in FIG. 1, and FIG. 2B shows a structure of each code word in the selective call signal.

As shown in FIG. 2A, the selective calling signal transmitted from the transmitting side is composed of a 576-bit preamble signal followed by a 32-bit SC signal. The preamble signal and the SC signal are used on the receiving side to synchronize with the transmitting side.

A radio selective calling receiver belongs to one of several groups, and a selective calling signal for calling its own device is transmitted only at a time allocated to the group to which the wireless device belongs. Therefore, after the radio selective calling receiver is turned on and receives and synchronizes the preamble signal and the SC signal, the radio selective calling receiver only needs to perform reception at the time allocated to the group to which the radio station belongs. The intermittent reception operation for receiving data only during the time allocated to the group to which the terminal belongs will be described later with reference to FIG.

As shown in FIG. 2A, after the SC signal, a selective call signal for the radio selective call receiver of each group is transmitted, and all groups (FIG. 2A shows eight groups).
After the transmission of the selective calling signal is completed, the SC signal is transmitted again, and then the selective calling signal to the radio selective calling receivers of each group is transmitted.

The selective paging signal for each group of paging receivers consists of two codewords, a first codeword and a second codeword. The SC signal is followed by the paging signal for all groups of paging receivers. The selective call signal is called one batch.

Each code word of the selective calling signal is shown in FIG.
The configuration is as shown in FIG. That is, 32
From the top, call number / message information identification bits (hereinafter simply referred to as “identification bits”), information bits,
It consists of a check bit and a parity bit.

The identification bit is 1 bit, and is a bit for identifying whether the code word is a code word indicating a selective call number of a radio selective call receiver to be called or a code word indicating message information. When this bit is 0, the code word is the selected call number, and when it is 1, the code word is message information.

The information bits are 20 bits. When the identification bit is 0, the call number of the radio selective call receiver to be called is set. When the identification bit is 1, the message information is set.

The check bit is 10 bits and the parity bit is 1 bit, that is, (31, 20) + 1B
The transmission error is corrected using the CH signal.

FIG. 3 is a diagram for explaining the intermittent receiving operation performed by the radio selective calling receiver 100 shown in FIG.
Indicates a non-reception time when a selective calling signal for calling the own device is not received, and (b) indicates a receiving time when the selective calling signal for calling the own device is received.

When the power of the radio selective calling receiver 100 is turned on, reception is first continued until a preamble signal is received, and the transmission side is synchronized by receiving the preamble signal and the subsequent SC signal.

As described above, the radio selective calling receiver 10
The calling number of the own device is stored in advance in the EEPROM 108 of 0, and the group to which the own device belongs is also stored. FIGS. 3A and 3B are diagrams showing a case where the radio selective calling receiver 100 belongs to group 2, and after receiving the preamble signal and the SC signal and synchronizing with the transmitting side, FIG. The power of the radio unit 102 is turned off and the intermittent reception operation is performed except for the time when the selective call signal to the radio selective call receiver belonging to No. 2 is transmitted.
By doing so, the radio selective calling receiver 100
Power consumption has been reduced.

At the time of non-reception when the selective call signal for calling the own device is not received, as shown in FIG. 3A, only when the selective call signal for the radio selective call receiver belonging to group 2 is transmitted. The power of the wireless unit 102 is turned on.

On the other hand, FIG. 3B shows a state at the time of receiving a selective call signal for calling the own device. That is, if the identification bit of the code word of the selective call signal for the radio selective call receiver of group 2 is 0 and the call number of the own device is set in the information bit, the radio select of another group that follows thereafter Since there is a possibility that a message to the own device may be transmitted at the time when the selective call signal to the paging receiver is transmitted, the identification bit is set to 0 next.
The reception is continued until the code word is transmitted.

In FIG. 3B, ID means that the identification bit is 0, that is, the code word of the selected call number, ME
S indicates that the identification bit is 1, that is, the code word of the message information. In the case of FIG. 3B, the call number of the own apparatus is set in the first code word of the selective call signal for the radio selective call receiver of group 2 and then the selective call signal for the radio selective call receiver of group 4 Since the identification bit has become 0 for the first time in the first code word of group 2, the first code word of the selective call signal for the radio selective call receiver of group 2 to the first code of the selective call signal for the radio selective call receiver of group 4 Receiving up to words continuously.

From the second codeword of the selective call signal for the radio selective call receiver of group 2 to the second codeword of the selective call signal for the radio selective call receiver of group 3, message information for the own apparatus is set. The radio selective calling receiver 100 stores this message information in the RAM 107.

FIG. 4 is a flow chart showing the processing of the radio selective calling receiver 100 shown in FIG.

The radio selective call receiver 100 includes a call number of its own device, a conversion code for converting a message (hereinafter, referred to as a “fixed-text conversion code”), and a character string corresponding to two numbers after the conversion code. And a database for designating the ringing tone is stored in the EEPROM 108 in advance.

In the radio selective calling receiver 100 according to the present invention, the switch 110 is used to enable the holder to edit the character string in the database and to specify the sound, and overwrite the contents before editing with the EEPROM 108. It is also possible to memorize it.

The processing will be described with reference to FIG. First, when the power of the radio selective calling receiver 100 is turned on, the control unit 10
4 reads out at least the calling number of the own device, the group number to which the own device belongs, and the fixed form conversion code from the EEPROM 108 and stores them in the RAM 107 (F-1). Then, it synchronizes with the transmitting side by receiving the preamble signal and the SC signal (F-2). And FIG.
The intermittent reception operation shown in (a) is started (F-3).

On the other hand, in step (F-4), if the identification bit of the first bit of the code word when the power of the radio selective calling receiver is turned on is 0, the next step (F-
When the process proceeds to 5), if the call number in the selected call signal matches the call number of the own device read in step (F-1), a message accompanying the call is taken out (F-6).
I do. If the identification bit is not 0, or if it does not match the calling number of the own device, the process returns to step (F-3) to continue the intermittent reception operation.

A message is taken out for each code word, and the message is stored in the RAM in the next step (F-7).
After storing the message in 107, the message is searched. During the message search, if it matches with the fixed form conversion code read in step (F-1) (F-8), it is further determined whether the two characters of the message after the fixed form conversion code are numbers (F-9). ), If YES, the EE in which the database shown in FIG. 5 corresponding to the two numbers is stored
The character string is read out from the PROM 108 (F-10), and the specified sounding tone is also taken out from the EEPROM 108 (F-10).
-12).

FIG. 5 shows an example in which a character string and a designated sounding tone are stored in a database in the form of a database. Two-digit number NO. Can be set by the holder using the switch 110 of the radio selective calling receiver.

If the answer is NO in step (F-8) or (F-9), the contents of the message text as it is and the contents of the notification sound set by the holder in the radio selective calling receiver are used. (F-11).

Thereafter, the radio selective calling receiver displays the character content in the above-mentioned step (F-10) or step (F-11) on the display unit 111 (F-13).

Next, based on the sound content in step (F-12) or step (F-11), the driving circuit 112
, The vibrating motor 114, the speaker 115, or the light emitting diode 116 is driven to start notification (F-14).

FIG. 6 shows an example of a ringing tone pattern of the ringing tone designated as the above-mentioned tone ringing tone. The ringing tone 1, the ringing tone 2, and the ringing tone 3 are controlled to sound only in the section of level 1 and to stop the ringing in the section of level 0. Thereby, the type of the sound can be changed.

The melody is caused to sound using the melody IC 113.

In the above embodiment, the character string is displayed on the display unit 111.
Is displayed, and a sound corresponding to the character string is generated. However, the character string may not be displayed on the display unit, and only the sound may be generated. To do so, when the holder of the radio selective call receiver edits the fixed phrase, the display characters are set to the unregistered state, only the notification sound at the time of reception is stored in the EEPROM 108, and the aforementioned message is included in the received message. When the stored fixed phrase is included, control is performed so that nothing is displayed on the display unit 111, so that only the sound at the time of notification is designated without displaying anything on the display unit.

[0047]

As described above, according to the present invention,
By deciding which fixed phrase number to use between the caller and the holder in advance, when the fixed phrase is received, the holder can determine from whom the call was made without looking at the display. It can be easily recognized by listening to the sound.

Further, since the holder can designate a corresponding sound based on the contents of the fixed phrase, the contents of the fixed phrase can be easily recognized by listening to the sound without looking at the display unit.

Further, if the display unit is not used,
It is also possible to generate only a sound without displaying anything on the display unit.

As described above, according to the present invention, there is no need to define the expansion in a new message such as specifying the ringing tone to be called on the caller side, and the service can be provided without changing the existing transmission system. .
