ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a radio communication device and a message display method for a radio communication device, and in particular, to a radio communication device and a message display method for a radio communication device by which received and stored information such as messages can be displayed to the user at high speed.
1. Description of the Prior Art
These days, radio communication systems or radio communication services employing radio selective calling receivers (called pagers, pocket bells, etc.) as handy radio communication devices are prevailing. Such radio selective calling receivers are being more and more required further improved operability or convenience of operation.
In “a radio selective calling receiver and a control method thereof” disclosed in Japanese Patent Application Laid-Open No.HEI9-215026, a radio selective calling receiver which can receive calls to two or more selective calling numbers is designed to be able to successively display received messages which have been sent to one of its selective calling numbers. For example, received messages which have been sent to a particular selective calling number that is used by the user for business (or for private use) are selected from the received messages and displayed on a display section successively, thereby the operability and the convenience of the user are improved. The radio selective calling receiver disclosed in the document stores each message, a reception address for indicating to which selective calling number the message has been sent, and reception time information indicating the time when the message was received, thereby the message display with respect to a particular selective calling number can be executed.
A “selective calling receiver” disclosed in Japanese Patent Application Laid-Open No.HEI2-152334 is provided with a second ROM (an IC card) which is detachable/attachable to the body of the selective calling receiver for storing a plurality of predetermined messages. The selective calling receiver receives a signal including 12-bit data indicating a selective calling number and 4-bit data indicating a message number, therefore, 16 types of messages can generally be displayed by the selective calling receiver depending on the message number (4 bits). When the selective calling number in the received signal matched that of the selective calling receiver, the selective calling receiver makes a beep for informing the user of the reception of a call, and generally displays one of 16 predetermined messages (stored in a first ROM) corresponding to the message number. Meanwhile, the second ROM stores 96 (16×6) predetermined messages (one message number corresponds to 6 predetermined messages corresponding to 6 time zones), and when the second ROM is connected to the body, the selective calling receiver executes message display depending on the reception time (a time zone in which the message was received) and the message number, thereby the number of displayable messages can be increased in comparison with the number of possible message numbers included in the signal.
A “selective calling receiver provided with display functions” disclosed in Japanese Patent Application Laid-Open No.HEI3-89639, which receives, stores and displays messages, can let the user know whether a message displayed on its display section is a message received today or not, by displaying the number of days which have elapsed since the reception of the message, along with the message. A “paging receiver provided with display functions” disclosed in Japanese Utility Model Application Laid-Open No.HEI2-90559 can also let the user know whether a message displayed on the display section is a today's message or not, by displaying the message with reception time information if the message is a today's message, and displaying the message with reception date information if the message is not a today's message.
A “selective calling receiver” disclosed in Japanese Patent Application Laid-Open No.HEI5-102915 does not inform the user of reception of a call if the present time (the time when the call is received) is within a predetermined call rejection time period, and informs the user of the call reception after the call rejection time period ended.
In a “radio selective calling receiver” disclosed in Japanese Patent Application Laid-Open No.HEI10-42329, two or more time periods (a first time period 09:00~16:59 and a second time period 17:00~08:59, for example) can be set, and when the user requested display of received messages, display depending on the present time (the time when the user requested the message display) is executed. For example, in the case where the user requested display of received messages on 10:00 which is included in the first time period, the radio selective calling receiver successively reads out each received message (which has been stored in its memory section in order of reception) from the memory section, judges whether the reception time of the message belongs to the first time period (for example), displays the message on its display section if the reception time of the message belongs to the first time period, and thereby messages which have been received during the first time period are successively displayed first in order of reception. Thereafter, messages which have been received during the second time period are successively displayed on the display section in order of reception in similar way. On the other hand, in the case where the user requested display of received messages on 19:00 which is included in the second time period, messages which have been received during the second time period are successively displayed first in order of reception, and thereafter messages which have been received during the first time period are successively displayed in order of reception.
The above radio selective calling receiver can select messages which have been received during one of the predetermined time periods and successively display the selected messages, depending on when the user requested message display. Therefore, the user can see selected messages which have been received during a predetermined time period that corresponds to the time when the user made the message display request.
However, in the radio selective calling receiver, judgment on whether each message has been received during a predetermined time period or not has to be executed on every reading of a message, and thus reading out and displaying of the messages which have been received during a fixed time period can not been executed very quickly.
SUMMARY OF THE INVENTION
It is therefore the primary object of the present invention to provide a radio communication device which is provided with functions for receiving messages via radio and displaying the messages, by which messages which have been received during a fixed time period can be displayed to the user at high speed.
Another object of the present invention is to provide a message display method for a radio communication device which is provided with functions for receiving messages via radio and displaying the messages, by which messages which have been received during a fixed time period can be displayed to the user at high speed.
In accordance with a 1st aspect of the present invention, there is provided a radio reception means, a memory means, a time period message memory means, a display means, an input means and a control means. The radio reception means receives a selective calling signal via an antenna and extracts a message that has been addressed to the radio communication device from the selective calling signal. The memory means stores the messages received and extracted by the radio reception means and information concerning the messages. The time period message memory means is provided to the memory means for storing information concerning messages which have been received during a fixed time period. The display means displays information such as the messages which have been stored in the memory
