The present invention relates to a radio selective call receiver, in particular a radio selective call receiver having a plurality of addresses.

A radio selective call receiver, such as, for example, a radio pager, having a plurality of registered address codes is described in, for example, Japanese Patent Laid-Open No. 1-288129. In this type of pager, an address code is assigned to a specific information source, respectively. For example, address codes A and B are each used to receive a message from a company in which the user of the pager works and to receive a message from the user's family. In addition, address codes C and D are useful for rapid reporting of currency rates or similar information services and athletic competition results, respectively. The pager displays a signal that has received a message related to one address at a time.

Preferably, with a pager of the type described above, the user can identify the caller who sent the message to the pager. For this purpose, the caller or source can send the name of the caller or the source with the message. However, this increases the amount of data, which increases the fee the caller has to pay.

In view of the above, Japanese Patent Laid-Open Publication No. 1-81338, for example, discloses a radio pager capable of displaying a caller's code together with a received message. In particular, given the fact that the address codes each assigned to a particular caller are included in the received signal, the pager displays the caller code corresponding to the address code. However, this type of pager introduces another problem that requires the user to remember the caller's code and the caller corresponding to the code. In particular, when the number of callers and the number of information sources is large, the memory of the user becomes unreliable. In addition, displaying one signal message at a time is not desirable from the point of view of efficiency.

It is therefore an object of the present invention to provide a radio selective call receiver capable of displaying a caller with a message without increasing the amount of data to be transmitted.

Another object of the present invention is to provide a radio selective call receiver capable of displaying a plurality of messages received from a single caller.

The radio selective call receiver of the present invention includes a display for displaying a received message and a name corresponding to the caller who sent the message. In addition, the radio selection call receiver includes a receiver for receiving a message and an address code, a memory for storing a message corresponding to the address code, and reading means for reading a message from the memory. When multiple messages from the caller are received or stored messages are read from memory, the messages are displayed with names.

According to the invention, the names respectively corresponding to the specific address codes to be received with the message are registered in advance in the pager. The name is displayed with the message. This makes it easy to identify the caller who sent the message.

Other objects, features and advantages of the present invention will become apparent from the following description with reference to the accompanying drawings. Like reference numerals denote like structural elements.

Referring to FIG. 1, there is shown a radio selective call receiver implementing the present invention. As shown, the radio select call receiver comprises a radio unit 1, an electrically erasable PROM (EEPROM; 2), a switching circuit (3), a decoder (4), a read-only memory (ROM; 5), a central processing unit ( A CPU 6), a random access memory (RAM) 7, a liquid crystal display (LCD) 8, an LCD driver 9, an antenna 10, a tone generator 11, and a speaker 12.

The paging signal from the base station, not shown in the figure, is received by the antenna 10 and applied to the radio section 1. The radio unit 1 demodulates the input signal. As shown in FIG. 2, the paging signal is composed of, for example, a preamble signal PA, a frame synchronization signal SC, and a plurality of groups F1-F8 each having two codewords. Each codeword includes an address code, a message code, and a temptation code indicating an address number. It is assumed that the address number is displayed in the first codeword of the fourth group F4. Then, if the address number is the same as the address number assigned to the receiver, the receiver receives a message following the address number. Upon detecting an idle codeword in group F2, the receiver terminates the reception.

3 shows a specific relationship between ID (identification) information and name corresponding to the address code. Preferably, the receiver has 12 different ID information and 6 different IDs. In FIG. 3, the numbers 1 to 6 represent IDs, and the letters A to D appended to the numbers 1 and 2 represent different functions belonging to the same ID. For example, 1-A, 1-B, 1-C, and 1-D belong to the same ID, but represent different functions based on function bits. Among the ID information, 1-A, 2-A, 5 and 6 are assigned to private messages, and 1-B and 2-B are assigned to messages from companies. In the column of names, a blank cell represents an unregistered state. Note that the number of ID information and the number of IDs shown in FIG. 3 are merely examples. This also applies to the number of names. For ID information indicated by numbers 3-6, the function bit may be labeled A as an example.

Referring back to FIG. 1, the signal demodulated by the radio 1 is applied to the decoder 4 via the data line 18. Detecting the assigned address number from the input signal, the decoder 4 delivers an address code corresponding to the address number and a message following the address code to the CPU 6 via the data bus 14. At the same time, the decoder 4 transmits the control information for storing the battery to the radio section 1 via the control line 19. The address code assigned to the receiver is read from the EEPROM 2 and sent to the decoder 4. The address bus 13 is used to transfer address information from the CPU 6 to the decoder 4, the ROM 5, and the RAM 7.

When the receiver is operated by the user, the switching circuit 3 transmits a command signal to the decoder 4 so that the received message can be displayed on the LCD 8. In response, the decoder 4 sends a command signal to the CPU 6 via the control line 15. ROM 5 stores a program for controlling the receiver.

The CPU 6 writes the received message to the RAM 7 while matching the address code based on the program stored in the ROM 5. In addition, in response to the command signal from the decoder 4, according to the program, the CPU 6 displays a message matched with the address code on the LCD 8 together with the address name. The LCD driver 9 drives the LCD 8.

When the address number detected by the decoder 4 is the same as the address number assigned to the receiver, the tone generator 11 transmits a tone signal to the speaker 12. In response, speaker 12 generates an alarm tone to inform the user that the call has been received.

In particular, the CPU 6 includes a group information receiving unit 61, a group recording control unit 62, a group reading control unit 63, and a group display control unit 64. These sections 61-64 are controlled by a program stored in the ROM 5. The group information receiver 61 receives an address code and a message from the decoder 4 and receives a command signal from the switching circuit 3 via the decoder 4. The group recording control unit 62 records the address code and the message in the selected area of the RAM 7 while matching the address code and the message with each other. In response to the command signal from the group information receiving section 61, the group reading unit 63 reads the message of the designated group (address) from the RAM 7 together with the address name. The group display control unit 64 causes the message read by the group read control unit 63 to be displayed on the LCD 8 together with the related information.

4 is referred to to explain how a receiver processes a received message. First, the received paging signal is demodulated by the radio unit 1 (step S101). The demodulated signal is transmitted to the decoder 4 via the data line 18. The decoder 4 detects the frame synchronizing signal SC from the demodulated signal and synchronizes various timing signals with the signal SC (step S103). As a result, the decoder 4 detects the address number from the demodulated signal (step S104) and compares it with the address number stored in the EEPROM 2 (step S105).

If the two address numbers are the same (YES in step S105), the decoder 4 determines whether or not a message follows the address number (step S106). If the answer to step S106 is no, the decoder 4 performs an operation of detecting an address number as described later. If the message exists (YES, step S106), the decoder 4 identifies the ID information matching the detected address code (step S107), and then interrupts the CPU 6 via the interrupt line 17. In response, the CPU 6 receives an address code and a message from the decoder 4 via the data bus 14 (step S109). The group information receiver 61 receives an address code and a message. The group recording control unit 62 records the address code and the message transmitted from the group information receiving unit 61 in the selected area of the RAM 7 while matching the address code and the message with each other (step S110).

5 shows the specific format in which the received message is stored in the RAM 7. As shown, the RAM 7 has message areas each assigned to one address name. The message is stored based on the address name, even if different ID information. In particular, messages relating to personal ID information are stored in the same group in the order received. The same applies to the message regarding the company ID information and the information ID information. The embodiment assigns a plurality of ID information to a single caller in consideration of the case where the amount of communication from a particular caller is relatively high. Thus, the message may be stored based on ID information instead of address name.

Referring again to FIG. 4, if no message follows the address number (NO in step S106), the decoder 4 interrupts the CPU 6 (step S111). In response, the CPU 6 separates the address code (step S112), and writes the address code in the selected area of the RAM 7 (step S113).

As described above, this embodiment stores the received message based on the address name by detecting the address code included in the paging signal.

6 shows another specific relationship between ID information and names corresponding to address codes. 7 illustrates another specific format in which a message is stored. As shown, the address names Shibayama are given ID information 1-A and 2-A, and the address name companies are given ID information 1-B and 2-B. The address names weather forecast and stock information are given ID information 3 and 4, respectively. In addition, ID information 5 and 6 are given to the address name and the like. As shown in FIG. 7, the received message is stored in the RAM 7 based on the address name.

In particular, the message display procedure for the embodiment is described with reference to FIG. When the switching circuit 3, preferably, the message read switch is pressed by the user (step S201), the decoder 4 detects it (step S202). In response to this, the decoder 4 transmits a control signal to the group read control section 63 of the CPU 6 via the control line 15 (step S203). The group read control unit 63 receives group information read from the RAM 7 in addition to the control signal. The group readout section 63 sends a display control signal to the group display control section 64 to display a group selection menu on the LCD 8 (step S204). In response, the group display control unit 64 activates the LCD driver 9. As a result, the LCD driver 9 causes the LCD 8 to display, for example, one group selection menu shown in FIG. 9A according to the group information (step S205). As shown in FIGS. 3 and 5, three different groups are provided, namely a company, an individual and information.

Whenever the switching circuit 3, preferably, the selection switch is pressed (step S206), the decoder 4 detects it (step S207) and changes the selection number which appears on the LCD 8 (step S208). ). When the input switch is pressed (step S209), that is, when a desired group to be read is input, the decoder 4 detects the first command signal (step S210). If the selection switch is not pressed (NO in step S206), the decoder 4 determines whether the input switch has been pressed. If the input switch is not pressed (NO in step S209), the pager waits for the paging signal to arrive (step S211).

When the group to be read is input, the group reading control section 63 determines whether the address 7 is registered in the RAM 7 (step S212). If the answer to step S212 is YES, the address name is read (step S213). The group reading control section 63 generates a command to display an address name and a message belonging to a designated group on the LCD 8. In response, the group display control section 63 causes the LCD 8 to display one group read image shown in FIG. 9B, for example, via the LCD driver 9 (step S214). FIG. 9B shows a specific state entered after the group company is selected on the image of FIG. 9A. In this case, three messages received from the company appear on the LCD 8, and the first received message phone leads the message group. When four or more messages belonging to the same group are received, a mark indicating the following can be displayed on the LCD 8. Then, the fourth or next messages appear on the LCD 8 when the selector switch is pressed.

As mentioned above, a group representing the caller's name is displayed with the message. This allows the user to easily identify the caller who sent the message.

Referring back to FIG. 8, when the address name is not registered (NO in step S212), the group read control unit 63 reads the address code from the RAM 7 (step S215). Thereafter, the group reading control section 63 instructs the group display control section 64 to display an address code and a message belonging to the designated group on the LCD 8. In response, the group display control unit 64 displays the address code instead of the address name on the LCD 8 (step S216).

Thus, when the selection switch is pressed by the user (step S217), the decoder 4 detects it (step S218). When the user presses the input switch after pressing the selection switch (step S219), the decoder 4 detects the second command signal (step S220). In response, the decoder 4 transmits a control signal to the group read control section 63. Upon receiving the second control signal, the group read control section 63 instructs the group display control section 64 to display the message selected on the basis of the group on the LCD 8 together with the address name. As a result, the group display control section 64 causes the LCD 8 to display an individual read image on the LCD 8, for example, as shown in FIG. 9C (step S221). FIG. 9C shows a specific state input after the third message is selected on the image of FIG. 9B. Although the third message is only partially visible on the image of FIG. 9B, it is displayed entirely along with the reception time and address name on the image of FIG. 9C.

The group reading control section 63 determines whether the desired message among the received messages has been displayed as a whole based on the operation of the user of the switch (step S222). For example, if the read switch is double clicked, the decoder 4 detects it. The group reading control section 63 causes the initial group selection image to appear on the LCD 8. When the read switch is pressed once, the preceding picture immediately reappears on the LCD 8. When the read switch is not pressed within a predetermined time, for example 40 seconds, the read and display control operation ends. This procedure also ends when the unshown power switch provided to the pager is turned off.

10 shows a specific configuration of the switching circuit 3. As shown, the switching circuit 3 has a menu switch 31, scroll switches 32 and 33, and a tap switch 34. The menu switch 31, the scroll switches 32 and 33, and the tap switch 34 each serve as the read switch, the select switch, and the input switch described above.

In summary, the radio selective call receiver of the present invention receives multiple address modes and subsequent messages, stores the message and address codes while matching the message and address codes, and matches the specified one of the address codes. Displays a message with a pre-stored address name. Thus, the receiver user can easily see who of the plurality of callers sent the message.

In addition, according to the present invention, address codes given the same address name are stored in the same group. The predetermined number of messages is displayed in response to the first command signal. Thereafter, a desired one of the messages is displayed in response to the second command signal. Thus, when multiple messages are received from the same caller, they are displayed in the same picture, allowing the user to select one of them. Thus, the pager of the present invention is easy and convenient to use.

So far, the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but this description is merely an example and should not be construed in a limiting sense. In addition, those skilled in the art may modify and change the embodiments of the present invention in various forms. Such modifications and variations are to be interpreted as falling within the scope of the appended claims.
