Abstract

When a message is received with receiving section 2, the received message is stored in message storing section 6 regardless of registering state of a group, which the received message belongs to. In such a case that the message is read from the message storing section 6, only the registered group names are displayed on a display unit 15 in list form. By selecting a desired group name from among the displayed group names, the user can see the content of the message belonging to the selected group. The registration and the cancellation of registration of each of the groups are performed by operating switches 10 to 13 and registering state of each of groups is stored in group name storing section 7.

Description

Background of the invention 1. Field of the Invention

The present invention is generally related to a selectively called wireless receiver having a message display function and a method for displaying received messages. More specifically, the present invention is directed to such a selectively called wireless receiver and a method for displaying received messages, capable of quickly finding out a desirable message from a plurality of received messages.

2. Description of the Related Art

Conventionally, selectively called wireless receivers having a message display function are provided widely. The selectively called wireless receiver of this type accumulates received messages in a message memory. Then, the received messages, which have been accumulated in the message memory, are displayed on a display unit according to the operation performed by the user.

Recently, the selectively called wireless receiver of this type is required to have high functionality. For example, the function is required that one desirable message can be quickly chosen from among a plurality of received messages and then displayed.

Under such a background, a selectively called wireless receiver is proposed to classify received messages into a plurality of groups. In this selectively called wireless receiver, the received messages are read from the message memory every group and then the read messages are displayed on a display unit.

For example, a selectively called wireless receiver which is disclosed in Japanese Laid Open Patent Disclosure (JP-A-Heisei 3-23727) has a plurality of call numbers and stores a received message into a message memory based on a corresponding one of these call numbers. Then, when a switch for the corresponding call number is operated, the received message corresponding to the call number is read and then the read message is displayed on a display unit. Hereinafter, this conventional technique is called the first conventional example.

Also, a selectively called wireless receiver which is disclosed in Japanese Laid Open Patent Disclosure (JP-A-Heisei 7-264644) classifies received messages into groups according to message distinguishing codes and stores the classified received messages into a message memory. Thereafter, the stored messages are read every group and then are displayed on the display unit. Hereinafter, this conventional technique is called the second conventional example.

By the way, in the above-mentioned first conventional example, the switch to read messages must be provided every call number. For instance, considering a case to receive information service, because the number of call numbers increases with increase of kinds of information service to be provided, the number of switches also increases. As a result, there is a problem that the design of an apparatus becomes difficult.

Also, a selectively called wireless receiver according to the above-mentioned second conventional example displays messages in order one by one from the group which contains a lot of received messages. As a result, the message having high urgency can be first displayed.

However, in a case that the user receives information service, there is a problem that even if the user tries to select a desired message, the selection (reading and display) according to intention of the user can not be achieved.

Description of the Preferred Embodiments

Referring now to the drawings, a selectively called wireless receiver according to an embodiment of the present invention will be explained. Fig. 1 is a schematic block diagram showing the structure of the selectively called wireless receiver.

In Fig. 1, an antenna 1 efficiently converts electromagnetic wave energy into an electric received signal in which a sync (synchronization) signal, a call signal and a message signal are contained. The electric signal is supplied to a receiving section 2. The receiving section 2 demodulates this electric signal to a base band signal. The demodulated base band signal is supplied to a decoding section 3.

The decoding section 3 detects a sync signal in the base band signal and then reads the received signal based on this detected sync signal. Also, the decoding section 3 checks whether or not a call number contained in the received signal is same as a call ID allocated to the present selectively called wireless receiver (hereinafter called "a self-call ID"). In this embodiment, the self-call ID has been stored in an ID storing section 5. When, it is determined that the same call number as the self-call ID is contained in the received signal, the decoding section 3 decodes the message signal following the self-call ID.

Fig. 2 shows a signal format of the POCSAG (Post Office Code Standardization Advisory Group) system employed in this embodiment. Because a reception operation of the selectively called wireless receiver of this type is generally known, a detailed explanation will be omitted. However, referring to Fig. 2, an operation of the above-mentioned decoding section 3 will be simply described.

The decoding section 3 establishes the bit synchronization of the received signal in accordance with a preamble signal 21 and detects a frame sync signal 22. Thereby, a reading timing of each word is recognized. Fig. 2 shows such an example that a self-call ID signal 23 is located in the third field from the frame sync signal. When the decoding section 3 detects this self-call ID signal 23, the decoding section 3 receives message words M1 (24), M2 (25) and M3 (26) (3 words, i.e. alphabet 8 characters in this example) which follows this self-call ID signal 23. Thereafter, when the decoding section 3 detects another ID signal or an IDLE signal 27, the decoding section 3 recognizes that transmission of the message signal is complete. It should be noted that a transmission device sends out the IDLE signal when there are not a call signal and a message signal to be sent out.

Referring Fig. 1 again, the decoding section 3 converts the received message signals M1 (24) to M3 (26) into ASCII codes and stores the converted ASCII codes in a message storing section 6 through a message processing section 4.

The ID storing section 5 stores equal to or more than one IDs (ID1, ID2, ID3, ···, IDn). Each ID can be allocated to one of selective call services and information services such as a weather forecast, news. Also, if well known technique is used, the message word M1 can be allocated to an information service distinguishing code and the message words M2, M3, ··· can be allocated to message data. In this case, only one ID is used for the information service.

The message storing section 6 stores the received messages which are classified into a plurality of groups such as the selective call, the information service and so on.

A group name storing section 7 stores a plurality of pairs each of which is composed of a group name and a registration flag. Each of the pairs corresponds to one group of received messages. Fig. 3 shows an example of contents in the group name storing section 7. The registration flag is used for the control of whether or not the group name corresponding to the registration flag is displayed in a group name list (to be mentioned in detail later). When a message is displayed on the display unit 15, the message which belongs to the group corresponding to one group name selected from the group name list is read from the message storing section 6. Therefore, in other words, the registration flag is used for the control of whether or not a request to read the message that belongs to each group is received. A method of setting the registration flag will be mentioned later.

Fig. 4 shows an example of contents in the message storing section 6 in which the received messages are stored every group name. When a message reading operation is performed, only the received messages that belong to the group for which the registration flag is set can be read from message storing section 6. On the other hand, when a message storing operation is performed, all of the received messages can be stored in the storing section 6 regardless of the condition of the registration flags.

It should be noted that one or more kinds of memories can be used for the ID storing section 5, the message storing section 6 and the group name storing section 7. For example, an EEPROM may be used for the ID storing section 5 and the group name storing section 7, and a RAM may be used for the message storing section 6. Also, a RAM may be used for all of these.

The decoding section 3 drives an informing section 8 when the self-call ID signal is detected and the message signal is received. As a result, a sound is generated from a speaker 9 to thereby inform the reception of the message signal. In addition to or instead of the speaker 9, various types of informing devices such as a vibrator which informs by vibration, a light-emitting diode which informs by light may be used for the informing section 8. If conventional technique is used, the decoding section 3 or the informing section 8 may be equipped with a auto-reset function. In this case, the sound generation is stopped when the predetermined time is elapsed after the sound generation is started.

Also, the decoding section 3 may be equipped with a manual reset function to stop the sound generation from the speaker 9. In this case, the decoding section 3 is driven through the message processing section 4 according to an operation of a menu switch 10, selector switch 11, background word switch 12 or forward switch 13. When the menu switch 10, selector switch 11, background word switch 12 or forward switch 13 is operated to stop the sound generation, the display driving section 14 is driven through the message processing section 4 to display the received messages on a display unit 15.

Next, operations of this selectively called wireless receiver with the above-described arrangement will now be explained with reference to flow charts indicated in Fig. 5A to Fig. 5G. Also, display examples of the display unit 15 shown in Fig. 6A to Fig. 9B will be referred to.

When a power supply (not shown) of this selectively called wireless receiver is turned ON or a reset operation is performed, an initializing process is first executed (Step S60). In this process, hardware in the selectively called wireless receiver is initialized, and initial values are set to the message storing section 6 and the group name storing section 7. When this initializing process is completed, the selectively called wireless receiver enters a wait state (Step S61). In this wait state, a message shown in Fig. 6A is displayed on the display unit 15. When either on of switches 10-13 is operated in this wait state, the selectively called wireless receiver operates as follows.

First, it is checked whether or not the menu switch 10 is operated (Step S62). When it is determined that the menu switch 10 is operated, the sequence operation advances to a menu selection mode processing (Steps S79 to S120) which will be described later. On the other hand, when it is determined that the menu switch 10 is not operated, it is checked whether or not the selection switch 11 is operated (Step S63). In this step, even if it is determined that the selection switch 11 is operated, the sequence operation advances to a next Step S64. That is, the operation of the selection switch 11 is ignored in this condition.

Next, it is checked whether or not the backward switch 12 is operated (Step S64). When it is determined that the backward switch 12 is not operated, it is checked whether or not the forward switch 13 is operated (Step S65). When it is determined that the forward switch 13 is not operated, the sequence operation returns to the Step S61. In short, when neither of the backward switch 12 and the forward switch 13 is operated, the selectively called wireless receiver enters the wait state again.

When it is determined that the backward switch 12 is operated in the above Step S64, or the forward switch 13 is operated in the above Step S65, the group name list is displayed on the display unit 15 (Step S66). In short, when the backward switch 12 or the forward switch 13 is operated in the wait state, the group name list is displayed on the display unit 15. In this case, only group names corresponding to the registration flag which has been set in "1" are included in the group name list. Fig. 7A shows an example of the group name list. First, a screen 100 shown in Fig. 7 is displayed as a initial group name list in which a cursor is located in front of a group name at a headline.

When the sequence operation of the Step S66 is completed, a check is done to see whether or not the forward switch 12 is operated (Step S67). When it is determined that the forward switch 13 is not operated, the sequence operation advances to Step S69. On the other hand, when it is determined that the forward switch 13 is operated, the cursor is carried forward for 1 line (Step S68) as shown in Fig. 7B. Thereafter, the sequence operation advances to Step S69.

In the step 69, it is checked whether or not the backward switch 12 is operated. Then, when it is determined that the backward switch 12 is not operated, the sequence operation advances to Step S71. On the other hand, when it is determined that the backward switch 12 is operated, the cursor is carried backward for 1 line (Step S70). Thereafter, the sequence operation advances to Step S71.

In the Step S71, it is checked whether or not selection switch 11 is operated. When it is determined that the selection switch 11 is operated, the sequence operation advances to a message display processing (Steps S73 to S78) which will be mentioned later. On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S72). When it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S67. Thereafter, the above-described sequence operations of Steps S67 to S72 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61. As a consequence, the selectively called wireless receiver enters the wait state again.

During execution of the above-described sequence operations of Steps S67 to S72, when the forward switch 13 is operated, the cursor is carried forward for 1 line. As a result, the display content on the display unit 15 is changed like screen 100 → screen 101 → screen 102 → screen 103···. It should be noted that when the forward switch 13 is operated in the state that the screen 102 has been displayed, the screen is scrolled up as shown as the screen 103 in Fig. 7D. Thereby, a new group name and a cursor are displayed on the bottom line on the display unit 15.

Similarly, when the backward switch 12 is operated, the cursor is carried backward for 1 line. As a result, display content on the display unit 15 is changed like ··· screen 103 → screen 102 → screen 101 → screen 100. It should be noted that when the backward switch 12 is operated in the state that the screen 100 has been displayed, the display content is not changed.

In the message display processing, as shown in Fig. 5B, one message is first displayed (Step S73). More specifically, first, one group corresponding to the group name indicated by the cursor is selected. Then, a head message, which belongs to the selected group, is read from the message storing section 6 and is displayed on the display unit 15. Consequently, the user can see a desired message by adjusting the cursor to the desired group name by operating the forward switch 13, the backward switch 12 and the selection switch 11. Fig. 6B shows a display example of the received message displayed when a group name of "weather forecast (local)" is selected.

When the sequence operation in the Step S73 is completed, a check is done of whether or not the forward switch 13 is operated (Step S74). When it is determined that the forward switch 13 is not operated, the sequence operation advances to Step S76. On the other hand, when it is determined that the forward switch 13 is operated, a following message is displayed (Step S75). That is, a message immediately after the currently displayed message is read from the message storing section 6 and is displayed on the display unit 15. Thereafter, the sequence operation advances to Step S76.

At the Step S76, it is checked whether or not the backward switch 12 is operated. When it is determined that the backward switch 12 is not operated, the sequence operation advances to Step S78. On the other hand, when it is determined that the backward switch 12 is operated, a previous message is displayed (Step S77). That is, a message immediately previous to the currently displayed message is read from the message storing section 6 and is displayed on the display unit 15. Thereafter, the sequence operation advances to Step S78.

At the Step S78, it is checked whether or not the menu switch 10 is operated. When it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S74. Thereafter, the above-described sequence operations of Steps S74 to S78 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations of Steps S74 to S78, the next message is displayed according to the operation of the forward switch 13 and the previous message is displayed according to the operation of the backward switch 12. Consequently, the user can find a desired message by operating the forward switch 13 and the backward switch 12.

It should be noted that even if the backward switch 12 is operated in the state that the head message in the selected group has been displayed, the display content is not changed. Similarly, even if the forward switch 13 is operated in the state that the bottom message in the selected group has been displayed, the display content is not changed. Also, since whether the selection switch 11 is operated is not checked in this message display processing, the operation of selection switch 11 is ignored.

In the menu selection mode processing, as shown in Fig. 5C, a menu is first displayed (Step S79). In this step, for instance, the menu shown in Fig. 8A is displayed on the display unit 15. Moreover, the selectively called wireless receiver enters a menu selection mode. The menu contains items such as "ALERT", "ALARM", "SETTING OF GROUP NAME LIST".

Next, a processing for moving the cursor according to the operation of the forward switch 13 and the backward switch 12 (hereinafter, called "a cursor processing") is performed (Steps S80 to S83). This cursor processing is the same as the processing performed in above-mentioned Steps S67 to S70. Next, it is checked whether or not the selection switch 11 is operated (Step S84). When it is determined that the selection switch 11 is operated, the sequence operation branches to Step S86, to thereby start the menu selection mode processing. On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S85). In this step, when it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S80. Thereafter, the above-described sequence operations of Steps S80 to S85 are repeatedly carried out. On the other hand, it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations of Steps S80 to S85, when the forward switch 13 is operated, the cursor is carried forward for 1 line. Similarly, when the backward switch 12 is operated, the cursor is carried backward for 1 line. Consequently, the user can select a desired item from a plurality of the items in the menu.

In the menu selection mode processing, it is checked whether or not the selected item is "ALERT" (Step S86). When it is determined that "ALERT" is not selected, the sequence operation advances to Step S88. On the other hand, when it is determined that "ALERT" is selected, alert processing is performed (Step S87). In this alert processing, a method of informing a warning can be set. After that, the sequence operation branches to Step S61.

At the Step S88, a check is done of whether or not the selected item is "ALARM". When it is determined that "ALARM" is not selected, the sequence operation advances to Step S90. On the other hand, when it is determined that "ALARM" is selected, an alarm processing is performed (Step S89). In this alarm processing, a setting of the time of morning call, an informing method of the morning call and so on can be set. After that, the sequence operation branches to Step S61.

At the Step S90, it is checked whether or not the selected item is "SETTING OF GROUP NAME LIST". When it is determined that item "SETTING OF GROUP NAME LIST" is not selected, the sequence operation returns to the Step S61. On the other hand, when it is determined that item "SETTING OF GROUP NAME LIST" is selected, display processing to set the group name list shown in Fig. 5D, is firstly performed (Step S91). In this step, a screen shown in Fig. 8B is displayed.

Next, the cursor processing is performed (Steps S92 to S95). Subsequently, it is checked whether or not the selection switch 11 is operated (Step S96). When it is determined that the selection switch 11 is operated, the sequence operation branches to Step S98. On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S97). In this step, when it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S92. Thereafter, the above-described sequence operations of Steps S92 to S97 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations of Steps S92 to S97, when the forward switch 13 is operated, the cursor is carried forward for 1 line. Similarly, when the backward switch 12 is operated, the cursor is carried backward for 1 line. Consequently, the user can select a desired item from the plurality of the items displayed in the menu (registration, deletion and all deletion).

At the Step S98, it is checked whether or not the selected item is "REGISTRATION". When it is determined that "REGISTRATION" is selected, the sequence operation advances to Step S101 to thereby execute registration processing (Steps S101 to S108) which will be mentioned later. On the other hand, when it is determined that "REGISTRATION" is not selected, it is checked whether or not the selected item is "DELETION" (Step S99). When it is determined that "DELETION" is selected, the sequence operation advances to Step S109 to thereby execute deletion processing (Steps S109 to S116) which will be mentioned later. On the other hand, when it is determined that "DELETION" is not selected, it is checked whether or not the selected item is "ALL DELETION" (Step S100). When it is determined that "ALL DELETION" is selected, the sequence operation advances to Step S117 to thereby execute all deletion processing (Steps S117 to S120) which will be mentioned later. On the other hand, when it is determined that "ALL DELETION" is not selected, the sequence operation branches to the Step S61.

In the registration processing, as shown in Fig. 5E, registration candidate group name display processing is firstly performed (Step S101). In this step, as shown in Fig. 8C, non-registered group names are displayed as registration candidate group names in a list form. Next, the cursor processing is performed (Steps S102 to S105). After that, it is checked whether or not the selection switch 11 is operated (Step S106). When it is determined that the selection switch 11 is operated, a registration flag is set (Step S107). That is, the registration flag corresponding to the group name indicated by the cursor is set to "1". Thereafter, the sequence operation returns to the Step S102.

On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S108). When it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S102. Thereafter, the above-described sequence operations of Steps S102 to S108 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations Steps S102 to S108, the user can set a registration flag corresponding to the desired group name to "1" by operating the forward switch 13, the backward switch 12 and the operating selection switch 11. Consequently, the newly selected group name is added to the group name list.

In the deletion processing, as shown in Fig. 5F, deletion candidate group name display processing is firstly performed (Step S109). In this step, as shown in Fig. 9A, already registered group names are displayed as deletion candidate group names in a list form. Next, the cursor processing is performed (Steps S110 to S113). Subsequently, it is checked whether or not the selection switch 11 is operated (Step S114). When it is determined that the selection switch 11 is operated, the registration flag which has been set is cleared (Step S115). That is, the registration flag corresponding to the group name indicated by the cursor is reset to "0". Thereafter, the sequence operation returns to the Step S110.

On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S116). When it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S110. Thereafter, the above-described sequence operations of Steps S110 to S116 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations of Steps S110 to S116, the user can reset the registration flag corresponding to the desired group name to "0" by operating the forward switch 13, the backward switch 12 and the operating selection switch 11. Consequently, the selected group name is deleted from the group name list.

In the entire of deletion processing, as shown in Fig. 5G, a confirmation message display processing is firstly performed (Step S117). In this step, a message for confirmation, as shown in Fig. 9B, is displayed on the display unit 15. Next, it is checked whether or not the selection switch 11 is operated (Step S118). When it is determined that the selection switch 11 is operated, all registration flags are cleared (Step S119). Thereafter, the sequence operation branches to the Step S61.

On the other hand, when it is determined that the selection switch 11 is not operated, it is checked whether or not the menu switch 10 is operated (Step S120). When it is determined that the menu switch 10 is not operated, the sequence operation returns to the Step S118. Thereafter, the above-described sequence operations of Steps S118 to S120 are repeatedly carried out. On the other hand, when it is determined that the menu switch 10 is operated, the sequence operation branches to the Step S61.

During execution of the above-described sequence operations of Steps S118 to S120, the user can clear the all registration flags in "0" by the operating selection switch 11. Consequently, the group name list is initialized.

Generally, received messages often include important information to the user and the information often has the nature that it should be confirmed at once when the message is received. The message of this type includes information such as a stock price and an exchange rate. These information changes every moment and also information value is very high.

According to this embodiment, the control of whether or not a message is displayed is performed every message group. As a result, since a desired message can be quickly found from a plurality of received messages, the selectively called wireless receiver according to this embodiment can quickly cope with the situation as described above.

In this embodiment, received messages are all stored in the message storing section 6 regardless of the registration flags. As a result, the user can confirm the contents of those messages by controlling the registration flags. However, according to whether or not the group to which the received message belongs is registered, there is a difference in the informing treatment when the terminating call occurs. That is, the decoding section 3 checks whether or not the group name corresponding to the received message is included in the group name list by referring the registration flag through the message processing unit 4. When it is determined that the group name corresponding to the received message is included in the group name list (registration flag=1), the informing section 8 is started to inform a terminating call. On the other hand, when it is determined that the group name corresponding to the received message is not included in the group name list (registration flag=0), the terminating call is not informed.

According to the present invention, the following effects are obtained.

(1) According to the selectively called wireless receiver of the present invention, group names chosen from among a lot of group names and also registered by the user are displayed in the list form. In this state, the user can choose a desired group name from among the displayed group names. As a result, one received message belonging to the selected group is displayed. Consequently, the user can read the desired message simply in a short time. In such a case that even if the message which belongs to the information source, i.e. the group of the numerous kinds can be received but it is enough that only the messages belonging to the limited groups can be displayed, the user should register only the group name corresponding to the limited group on the group name list. Because the registration is accomplished, in case of the message reading, an unnecessary group name is not displayed, and only the limited group name is displayed in a group name list. As a result, the user can immediately select a desired group name from the group name list, and also can read a desired message from among a plurality of the received messages contained in the group corresponding to the selected group name.

(2) According to the selectively called wireless receiver of the present invention, the information suitable for a use time zone, a use situation and a purpose of the use can be retrieved. That is, because a group name list can be edited by registering and deleting the information source, the user can select the desired information source to be read according to the purpose of the use and so on.

(3) Regardless of the registration of the group name, received messages are all stored in the message storing section. As a result, even if the message which does not belong to the registered group is received, the message can be read by registering the group name corresponding to the unregistered group thereafter.

(4) A report is performed when the message that belongs to the group corresponding to the registered group name is received, however, when the message that belongs to the group corresponding to the unregistered group name is received, the report is not performed. As a consequent, there is an advantage not to trouble a user even if the message having no importance or the message having no urgency is received.
