Radio paging receiver with message displaying function and method of controlling the same

Abstract: A radio paging receiver which stores messages accompanied by paging calls into directories corresponding to paging numbers and displays the stored messages in a particular directory together and successively, in which the directory which has the highest preferential ranking to display stored messages is determined by an user of the radio paging receiver, or from among the directories which correspond to a plurality of paging numbers selected by the user the highest preferential display ranking is given to the directory corresponding to the paging number of the latest paging call.

Description: This invention relates to a radio paging receiver, and more particularly to a radio paging receiver with a displaying function which stores messages accompanied by paging calls in directories provided with corresponding paging numbers and displays stored messages in an arbitrary directory together and successively. As an example of a conventional radio paging receiver with a message displaying function, a "Paging Receiver (Selective Call Receiver)" is disclosed in JP-A-257127/92. The paging receiver mentioned above has a plurality of paging numbers and received message information with paging calls are sorted and displayed together in accordance with call discrimination information corresponding to the paging numbers. In particular, when various information services are received by a single receiver in such a manner for instance that stock price information is received with a certain paging number while exchange rate information is received with another paging number, message information can be sorted and displayed together in accordance with the call discrimination information, and consequently, understanding or recognition of information from each information service is remarkably facilitated for a user. However, the paging receiver cannot display the message information belonging to a particular information service preferentially to other message information. US-A-5 075 684 discloses a selective call message management system with a three step hierarchy for selecting source files. Source files with unread messages are selected first, source files having a priority attached and which have not been previously selected are selected next, and remaining previously unselected source files are selected finally. It is an object of the present invention to provide a radio paging receiver and a method of controlling the paging receiver, wherein, when reception messages stored in directories corresponding to paging numbers are to be displayed from directory to directory, messages stored in a directory corresponding to a particular paging number can immediately be displayed preferentially according to-the working mode setting by switch operation by the user of the paging receiver. It is aimed that the user can confirm messages sent through a particular paging number immediately at any time, or he can confirm messages sent through one of the selected paging numbers when a new message is displayed through the same number. This object is achieved with the features of the claims. An embodiment of the present invention is described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a radio paging receiver with a message displaying function of the present invention; FIG. 2 is a diagrammatic view illustrating an example of a directory composition in a RAM of the radio paging receiver shown in FIG. 1; FIG. 3 is a flow chart illustrating a flow for setting of a home directory or "AUTO CHANGE" directories in the radio paging receiver shown in FIG. 1; FIG. 4 is a flow chart illustrating a flow from reception of a message to displaying of the message for confirmation in the radio paging receiver shown in FIG. 1; and FIG. 5 is a schematic view showing display contents of a display unit in different steps shown in FIGS. 3 and 4. Referring to FIG. 1, a radio paging receiver with message displaying function of the present embodiment includes antenna (ANT) 1, radio unit 2 for amplifying and demodulating a radio signal received by antenna 1, ID-ROM 4 for storing a plurality of paging numbers of the radio paging receiver, announcement unit 5 for announcing that the receiver is being called, display unit 6 for displaying a message of the received radio signal, RAM 7 for storing received messages in directories which correspond to paging numbers, operation unit 8 on which a plurality of switches (including a menu display switch (SWA), a settlement switch (SWB) and a selection switch (SWC)) operated by a user of the radio paging receiver are mounted, and controller 3 for controlling operation of the receiver such as confirmation and announcement of reception of paging calls to the receiver, and storing and displaying of the received messages in response to manual operation of switches of operation unit 8. The user can, while observing the screen of display unit 6, manually operate a switch or switches of operation unit 8 to set a home directory mode and select a directory (home directory) which has the highest preferential ranking for displaying among all the directories or to set an "AUTO CHANGE" mode and select a plurality of directories ("AUTO CHANGE" directories) to one of which the highest preferential display ranking is automatically given in response to an occurrence situation of paging calls. In "AUTO CHANGE" mode, the preference is given to a directory among those selected directories which corresponds to a paging number of the latest paging call. Accordingly the preferential display directory varies in response to an occurrence situation of paging calls. FIG. 2 is a diagrammatic view illustrating an example of a directory composition in RAM 7. For example, a home directory 21 has the highest preferential display ranking, and ID-B denotes a paging number of home directory 21, and messages B-1, B-2 and B-3 are all messages stored in home directory 21. Meanwhile, directories 22, 23 and 24 have ordinary display ranking other than the highest preferential display ranking and have paging numbers ID-A, ID-B and ID-C, respectively. Further, messages A-1 and so forth, messages C-1 and so forth, and messages D-1 and so forth have been received and stored in the directories 22, 23 and 24 in RAM 7. In the radio paging receiver shown in FIG. 1, when it is in a home directory mode, the user can depress a switch or switches of operation unit 8 to arbitrarily set a home directory corresponding to the paging number ID-B for example. However, when the radio paging receiver is in an "AUTO CHANGE" mode, he can set a plurality of "AUTO CHANGE" directories corresponding to paging numbers ID-A and ID-C for example, whose preferential display ranking are automatically determined in accordance with whichever paging number is that of the latest paging call received. In this instance, the preferential display directory is not fixed, but varies between ID-A and ID-C. Next, operation of the switches and display contents are described in detail with reference to FIGS. 3, 4 and 5. It is to be noted that, in FIG. 5, reference symbols 1-A, 1-B and 1-C denote directories (DIR) corresponding to the paging numbers ID-A, ID-B and ID-C in FIG. 2, respectively. First, a method of setting a home directory or "AUTO CHANGE" directories is described. Referring to FIG. 3, if the user depresses switch SWA of operation unit 8, then "MENU" screen (FIG. 5(a)) is displayed on display unit 6 (step 31). Then, one of "1: ALARM", "2: TIMER" and "3: DIRECTORY SET" is selected by depression of switch SWC (step 32). If the user selects "3: DIRECTORY SET" in this step 32 and then depresses switch SWB, then "DIRECTORY SETTING MODE" screen (FIG. 5(b)) is displayed on display unit 6 (step 33). Then, the user depresses switch SWC to select one of "1: HOME DIRECTORY" mode and "2: AUTO CHANGE" mode (step 34) and depresses switch SWB to settle the result of the selection (step 35). If the user selects "1: HOME DIRECTORY" mode in step 34 and then settles the selection in step 35, then "HOME DIRECTORY" screen (FIG. 5(c)) is displayed on display unit 6. Thereupon, if the user depresses switch SWC to select "2: 1-B" (step 36) and then depresses switch SWB to settle the selection, then setting of a home directory 1-B is completed thereby (step 37). On the other hand, if the user selects "2: AUTO CHANGE" mode in step 34 and settles the selection in step 35, then "AUTO CHANGE DIRECTORY" screen (FIG. 5(d)) is displayed on display unit 6. Thereupon, if the user depresses switch SWC to select ON for "1: 1-A" and "3: 1-C" but keeps OFF for "2: 1-B" (step 38) and then depresses switch SWB to settle the selections, then setting of "AUTO CHANGE" directories 1-A and 1-C is completed thereby (step 39). Next, a process from reception of a paging call to displaying of stored messages for confirmation is described with reference to FIG. 4. If a message to be stored into directory 1-C is received for instance (step 41) after setting of a home directory 1-B or "AUTO CHANGE" directories 1-A and 1-C is completed in step 37 or step 39, whichever a "HOME DIRECTORY" mode or an "AUTO CHANGE" mode has been set, the directory name "DIR: 1-C" and a stored message ">ABCDEFG" in the same directory are displayed as seen in FIG. 5(e) at the time of announcing the reception of the paging call (step 42). Then, if one of the switches of operation unit 8 is depressed, the announcement comes to an end (step 43) and the displaying is stopped and the waiting state (initial screen) is restored (step 44). The announcement of the reception of a paging call and the displaying of the messages stored as described above are performed for all paging calls received with messages irrespective of the display ranking. Thereafter, when necessary, the user depresses the switch SWC to display the stored messages to confirm them (step 45). In the "HOME DIRECTORY" mode, if the home directory is set to directory 1-B, a message screen (FIG. 5(f)) of "DIR: 1-B" is displayed immediately on display unit 6. (Here, if the user depresses switch SWC to scroll the screen in order to confirm the messages of directory 1-C, then a message screen (FIG. 5(g)) of "DIR: 1-C" can be displayed.) On the other hand, in the "AUTO CHANGE" mode, if the latest message received and stored in the auto change directories 1-A and 1-C is the message stored in directory 1-C, when the user depresses switch SWC in step 45, directory 1-C takes preference and the message screen (FIG. 5(g)) of "DIR: 1-C" is displayed, thereby completing confirmation of the messages. In this instance, it is to be noted that messages 2: UCHIDA and 3: JUNE in FIG. 5(g) are messages received and stored after storing the message 1 ABCDEFG shown in Fig. 5(e). In the "AUTO CHANGE" mode, when directory 1-B has been set to "OFF" in steps 38 and 39, even if one of the messages of directory 1-B is the latest message, the directory 1-B does not have the highest preferential ranking. In this mode, as described above, the messages stored in the directory 1-C (FIG. 5(g)) are displayed preferentially. (If the user depresses switch SWC to scroll the screen, then the messages of the directory 1-B (FIG. 5(i)) can be displayed.) In this manner, it can be seen that a user who always wants to confirm the messages stored in a particular directory preferentially should use the home directory mode, but another user to whom the information stored in several selected directories are equally important should use "AUTO CHANGE" mode.
