Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a radio selective calling receiver, in particular, to a controlling means that the user of the receiver sets up a receiving operation and a reception notifying operation for each sending user. The present invention also relates to a setup controlling means that is disposed in a TDMA type or CDMA type portable telephone unit. 
     2. Description of the Related Art 
     A conventional radio selective calling receiver (a well-known pager, an IS-136, an IS-95, FLEX, FLEX-TD, a pocket-bell, a PDC(Personal Digital Cellular) and so forth) (hereinafter referred to as receiver) has a plurality of notifying means such as a sounding means (for example, a speaker), a vibrating means (for example, a motor), and a lighting means (for example, an LED). One notifying means is used for all received signals. Alternatively, a plurality of calling numbers are assigned respective notifying means. 
     In recent years, a receiver with a password-protected reception notification controlling function has been accomplished. Such a receiver has been disclosed in for example Japanese Patent Laid-Open Publication No. 6-152499. In this receiver, a sending user can be identified with a password and time data. 
     FIG. 1 is a block diagram showing an example of the structure of a receiver corresponding to the above-described related art reference. In the receiver, a signal is received from an antenna  201 . The received signal is supplied to a radio portion  202 . 
     The radio portion  202  demodulates the received signal. The demodulated data is input to a controlling portion  203 . Under the control of the controlling portion  203 , a selective calling number collating portion  205  collates a selective calling number contained in the received data and a local selective calling number stored in an ID-ROM  204 . 
     When they match, a password collating portion  207  collates a character string contained in a received massage of the received data and a password stored in a password storing portion  206 . When they match, a notifying portion  209  notifies the user of the received data. When they do not match, the controlling portion  203  compares the current time counted by a clock portion  212  and notification restriction time and restriction cancellation time that have been set to a setup time storing portion  208  so as to determine whether the notification of the received data has been restricted. 
     When the notification of the received data has not been restricted, the notifying portion  209  notifies the user of the received data. When the notification of the received data has been restricted, the received message is stored to a message storing portion  211 . After the notification of the received message has been canceled, the notifying portion  209  notifies the user of the received data. 
     In the above-described radio selective calling receiver, a plurality of reception priority levels and notifying means can be assigned to each sending user. In addition, the receiver has the reception notification restricting function for restricting reception notification corresponding to each time range. However, when there are a large number of sending users, it is troublesome to assign notifying means and valid time to the sending users. In other words, it is difficult to manage (newly register, change, delete, and check) notifying means and notification valid time ranges for these sending users. 
     SUMMARY OF THE INVENTION

     DESCRIPTION OF PREFERRED EMBODIMENTS 
     Next, with reference to the accompanying drawings, embodiments of the present invention will be described. 
     First Embodiment 
     FIGS. 2A and 2B are block diagrams showing examples of the structures of receivers according to a first embodiment of the present invention. In FIG. 2A, a radio selective calling receiver (hereinafter referred to as receiver) according to the first embodiment comprises a radio portion  1 , a main controlling portion  2 , an ID-ROM portion  3 , a message storing portion  6 , a data inputting portion  7 , a sending user calling information storing portion  10 , a sub-controlling portion  9 , a clock-calendar portion  8 , a reception notifying portion  4 , and a displaying portion  5 . The radio portion  1  receives and demodulates a radio calling signal. 
     The main controlling portion  2  processes a received signal and controls a receiving operation and so forth. The ID-ROM portion  3  stores a local calling number and so forth. The message storing portion  6  stores a received message and so forth. The data inputting portion  7  inputs sending user information and so forth. The sending user calling information storing portion  10  sets up and stores sending user information, calling information corresponding thereto, and time information for validating the calling information. 
     The sub-controlling portion  9  compares sending user information contained in a received signal and sending user information stored in the sending user calling information storing portion  10 , searches calling information and time information therefrom, and performs a controlling operation corresponding to the calling information. The clock-calendar portion  8  counts time and date. The reception notifying portion  4  notifies the user of received data. The displaying portion  5  outputs visible information to the user. 
     As notifying means of the reception notifying portion  4 , a sounding means (for example, a speaker), a vibrating means (for example, a vibrating motor), a lighting means (for example, an LED), and so forth can be used. 
     FIG. 2B shows the structure of which a portable telephone apparatus comprised the selective calling receiver shown in FIG. 1 and a radio transmitter/receiver is combined with a portable telephone unit that mutually communicates voice and data therewith. 
     A radio portion  1  has a transmitting portion  1   a  and a receiving portion  1   b . The transmitting portion  1   a  is connected to an antenna  1   d  through a combining-branching portion  1   c . The transmitting portion  1   a  modulates a base band signal corresponding to assigned frequency and slot under the control of a main controlling portion  2   a  and transmits the resultant radio wave to a base station. The receiving portion  1   b  converts a signal received from the combining-branching portion  1   c  into a base band signal. The receiving portion  1   b  is used in common with a receiving portion of the selective calling receiver. The main controlling portion  2   a  determines whether the received signal is for the selective calling receiver or the portable telephone unit corresponding to the reception frequency, the data type, and so forth, executes a signal process corresponding to the determined result, and adaptively outputs the resultant signal. 
     The receiver shown in FIG. 2B also has a microphone  12  and a speaker  13 . The microphone  12  converts an audio signal into an electric signal. The speaker  13  outputs an audio signal. With the microphone  12  and the speaker  13 , a message can be transmitted and received as an audio signal. Thus, the portable telephone unit can be provided with many functions as well as features of small size and light weight. A reception notifying portion  4  and the speaker  13  may be structured in common. In addition, information stored in a message storing portion  6  may be output from the speaker  13 . 
     The function as a radio selecting calling receiver (or a pager) of the portable telephone unit shown in FIG. 2B is the same as that shown in FIG.  2 A. The reception setup conditions and other setup conditions of the portable telephone unit are the same as those that will be describe later. 
     Next, the operation of the receiver according to the first embodiment of the present invention will be described. 
     Considering particular sending user information for assigning priority levels to individual sending users and sending user groups, the user of the receiver operates the data inputting portion  7  through the main controlling portion  2  and the sub-controlling portion  9  so as to set up calling information (immediate notification mode, message hold and notification stop mode, and so forth) and a calling information valid time range. The sending user calling information is stored in the sending user calling information storing portion  10 . Calling information and time information corresponding to sending user information can be stored as a plurality of information items for each sending user. After the current time and date are set up to the clock-calendar portion  8 , it counts the current time. 
     A sending user transmits sending user information as well as a calling number of the receiver and a message. The sending user information has been arranged between the sending user and the receiving user. 
     The transmitted information as a radio signal is received and demodulated by the radio portion  1 . The demodulated data is supplied to the main controlling portion  2 . The main controlling portion  2  collates a calling number contained in the received data and a local calling number stored in the ID-ROM portion  3 . When they match, the main controlling portion  2  extracts a message signal and a sending user information signal preceded by the calling number and supplies the extracted message signal and sending user information signal to the sub-controlling portion  9 . 
     The sub-controlling portion  9  collates sending user information stored in the sending user calling information storing portion  10  and the sending user information signal received from the main controlling portion  2 . When they match, the sub-controlling portion  9  extracts calling information and time information from the stored sending user information and compares/collates the extracted time information and current time and date counted by the clock-calendar portion  8 . The sub-controlling portion  9  supplies a calling information signal for a calling means corresponding to the matched time information to the main controlling portion  2 . The main controlling portion  2  causes the displaying portion  5  to display a message corresponding to the calling information signal and the reception notifying portion  4  to operate. 
     FIG. 6 shows an example of a data structure in the sending user calling information storing portion  10 . Corresponding to reception priority levels A, B, . . . E, notifying operation, notifying means, operation time range (start time and end time), calendar information  1  (start day and end day), calendar information  2  (state date and end date) are recorded. 
     In FIG. 6, “O icon” in notifying operation field represents that the receiver can receive a signal and notify the user of the received signal. “X icon” represents that the receiver does not receive a signal or can receive a signal but does not notify the user of the received signal. “Speaker icon” in notifying means field represents that the receiver uses a speaker sound (conventional beeping sound). “Note  1  icon” and “note  2  icon” represent that the receiver uses a speaker sound in note  1  and a speaker sound in note  2 , respectively. “≈icon” represents that the receiver uses a vibration of a vibrating motor. “Speaker icon with slant line” represents that the receiver uses a character notification rather than a sound notification. “Pen icon” represents that the receiver uses neither a reception notification nor a character notification, but stores received data in the memory. 
     FIGS. 7,  8 A,  8 B,  9 , and  10  show examples of setup screens of sending user calling information. FIG. 7 shows the case that a normal sound notification (calling information) with a speaker (speaker icon) every day [SUN-SAT] for 24 hours [00:00-24:00] from Aug. 1, 1997 (endless) [97/08/01-∞] has been assigned to sending user information &lt;A&gt;. FIGS. 8A and 8B show the case that notification information has been assigned to sending user information &lt;B&gt;, &lt;C&gt;, . . . , &lt;E&gt; on two pages (notification information has not been assigned to sending user information &lt;F&gt;). All the sending user calling information can be managed on these screens. In this example, notifying means for sending user information &lt;B&gt; is being changed (reverse indication at cursor position). 
     FIG. 3 is a flow chart showing an example of a sending user calling information managing process according to the present invention. 
     In FIG. 3, in normal reception standby state at step S 1 , the user selects information management mode in the receiver at step S 2 . The sub-controlling portion  9  searches sending user calling information from the sending user calling information storing portion  10  at step S 3  and determines whether the sending user calling information has not been set up at step S 4 . When the sending user calling information has not been set up, the sub-controlling portion  9  determines whether or not the user wants to set up the sending user calling information at step S 5 . When the determined result at step S 4  is No, the user selects desired information at step S 6 . FIGS. 8A and 8B show examples of screens in the sending user calling information managing process. Thus, the user can easily check information that has been set up. 
     At step S 5 , when the determined result at step S 5  is No, the flow returns to step S 1 . When the determined result at step S 5  is Yes, the flow advances to step S 7 . At step S 7 , the sub-controlling portion  9  performs information setup process. 
     After the user has decided the selected information at step S 8 , the sub-controlling portion  9  determines whether or not the user has acknowledged the changed information at step S 9 . When the determined result at step S 9  is No, the flow returns to step S 1 . 
     When the determined result at step S 9  is Yes, the sub-controlling portion  9  determines whether the changed information is sending user information, calling information, or time information at step S 10  and displays available alternatives at step S 11 , S 12 , or S 13 . 
     FIG. 9 shows examples of available alternatives displayed in the case that the notifying means change for the sending user information &lt;B&gt; has been selected (an example at step S 12 ). In this case, the notifying means is changed from a vibrating notification (≈indication) to a musical notification (note indication). 
     When the determined result at step S 10  is sending user information, when the user selects information to be changed at step S 14 , the sub-controlling portion  9  determines whether the changed sending user information has not been registered (for example, when the sending user information &lt;A&gt; is changed to &lt;H&gt;, the sub-controlling portion  9  determines whether the sending user information &lt;H&gt; has not been registered) at step S 17 . When the determined result at step S 17  is Yes, the flow advances to step  618 . At step S 18 , the sub-controlling portion  9  determines whether or not user has acknowledged the changed information. When the determined result at step S 17  is No, the flow returns to step S 14 . 
     When the determined result at step S 10  is calling information, when the user selects desired information at step S 15 , the flow advances to step S 18 . At step S 18 , the sub-controlling portion  9  determines whether or not the user has acknowledged the changed information. 
     When the determined result at step S 10  is time information, the user changes the time information at step S 16 . Thereafter, the flow advances to step S 19 . At step S 19 , the sub-controlling portion  9  extracts the current time and date from the clock-calendar portion  9  and determines whether the changed time information is consistent (namely, when the time range from Oct. 1, 1997 to Oct. 31, 1997 has been set up, if the current date is Sep. 1, 1997, the changed time information is inconsistent) at step S 20 . When the determined result at step S 20  is Yes, the flow advances to step S 18 . At step S 18 , the sub-controlling portion  9  determines whether or not the user has acknowledged the changed information. When the determined result at step S 20  is No, the flow returns to step S 16 . 
     When the determined result at step S 18  is Yes, the sub-controlling portion  9  stores the changed information to the sending user calling information storing portion  10  at step S 21 . Thus, the sub-controlling portion  9  completes the information setup changing process at step S 22 . When the determined result at step S 18  is No, the flow returns to step S 1 . FIG. 9 shows an example of a screen in the case that setup information has been changed. 
     FIG. 4 is a flow chart showing an example of a sending user calling information setup process according to the present invention. 
     At step S 7  shown in FIG. 3, the receiver enters the All information setup mode. Thereafter, the flow advances to step S 30 . At step S 30 , the user sets up sending user information so as to assign a priority level to a sending user. Thereafter, the user sets up desired calling information (notifying method and so forth) corresponding to the sending user information at step S 31 . Next, the user sets up desired time information (start time, end time, and so forth) for validating the calling information at step S 32 . 
     The sub-controlling portion  9  extracts the current time and date from the clock-calendar portion  9  at step S 33  and determines whether or not the time information that has been set up is consistent at step S 34 . When the determined result at step S 34  is Yes, the sub-controlling portion  9  registers the time information to the sending user calling information storing portion  10  at step S 35 . Thereafter, the sub-controlling portion  9  determines whether the user continues to set up sending user calling information at step S 36 . When the determined result at step S 36  is No, the flow advances to step S 37 . At step S 37 , the sub-controlling portion  9  completes the information setup mode. 
     When the determined result at step S 36  is Yes, the flow advances to step S 38 . At step S 38 , the user sets up sending user information. At step S 39 , the sub-controlling portion  9  determines whether or not the setup sending user information has not been registered. When the determined result at step S 39  is Yes, the flow returns to step S 31 . When the determined result at step S 39  is No, the flow returns to step S 38 . 
     FIG. 5 is a flow chart showing an example of a receiving process of the sub-controlling portion  9 . 
     In FIG. 5, at step S 41 , the sub-controlling portion  9  waits for information. A sending user information signal is input from the main controlling portion  2  to the sub controlling portion  9 . The sub controlling portion  9  extracts sending user calling information from the sending user calling information storing portion  10  at step S 43  and collates the input sending user information signal and the extracted sending user information at step S 44 . 
     When they match, the sub-controlling portion  9  extracts calling information and time information from the input sending user calling information at step S 45  and extracts the current time and date from the clock-calendar portion  8  at step S 46 . 
     The sub-controlling portion  9  determines whether or not the time information extracted at step S 45  and the current time are consistent at step S 47 . When the determined result at step S 47  is Yes, the sub-controlling portion  9  supplies the extracted calling information as a first calling information signal to the main controlling portion  2  at step S 48 . 
     When the determined result at step S 47  is No, the sub-controlling portion  9  supplies a second calling information signal to the main controlling portion  2  so as to suspend the reception notification until the valid setup time and store only the message to the message storing portion  6  at step S 50 . 
     When the determined result at step S 44  is No, the sub-controlling portion  9  supplies a reception cancel signal to the main controlling portion  2  at step S 49 . In this case, the reception cancel signal represents that sending user information has not been registered. 
     After the sub-controlling portion supplies the first calling information signal at step S 48 , the second calling information signal at step S 50 , or the reception cancel signal at step S 49  to the main controlling portion  2 , the sub-controlling portion  9  completes the receiving process at step S 51 . Thereafter, the flow returns to step S 41 .

     As described above, in the radio selective calling receiver according to the present invention, sending user information for identifying a sending user, calling conditions for setting up reception priority levels, notifying means, and so forth, and time information for validating setups are independently stored. With a means for combining such information, various information can be easily registered, changed, and managed. 
     According to the present invention, various information is set up in advance. Thereafter, all information is read and displayed. Thus, desired information can be properly managed on a screen. Consequently, the user of the receiver can easily set up information of a plurality of sending users, receiving means, reception notifying means, and restriction of a reception time range. Thereafter, the user can easily manage (for example change and check) such information. 
     In addition, since there are means that allow the user of the receiver to identify a sending user, to assign receiving priority levels and reception notification priority levels of sending user information, and to set and control receiving means and reception notifying means corresponding to individual time ranges. Thus, information transmitted by important sending users can be received and notified in higher priority levels than other information. When the user of the receiver controls reception time ranges along with sending users, important information can be securely received with a plurality of reception notifying means without need to increase discrete calling numbers. 
     In addition, since the user of the receiver can register sending users, he or she can prevent the receiver from receiving information other than the registered sending users. Moreover, since the user of the receiver can identify and register each sending user, he or she can more easily register and change various data than he or she sets up a password. Thus, the user of the receiver can prevent the receiver from receiving mischievous or mistaken calls without need to set up a password. 
     Although the present invention has been shown and described with respect to a best mode embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions, and additions in the form and detail thereof may be made therein without departing from the spirit and scope of the present invention.
