Abstract

PROBLEM TO BE SOLVED: To obtain a receiver whose storage efficiency of a message is enhanced by each update period of an information message by receiving a radio selective calling signal and the message succeeding thereto, retrieving a valid year, month, day/time in the message when the signal is coincident with a call number of its own receiver and storing the retrieval result with the message. SOLUTION: In the case of receiving a message, a signal demodulated from a signal received by a radio control means section 100 is given to a decoder 101. The decoder 101 compares and collates a call number of its own receiver registered in an EEPROM 106 with a received call number. In the case that the call number is coincident, a message area is extracted to produce interruption to a control section 102. The control section 102 extracts a message from the decoder 101 and a retrieval section 104 retrieves whether or not a valid year, month, day/time information is in existence in the received message and registers the valid year, month, day/time information to a storage section 103 with the message when in existence.

Control means for detecting the coincidence with the calling number and processing the information signal following thereto; storage means for storing the information signal; display means for displaying the information signal of the storage means; and notification based on the output of the control means. Means and a time selection means, wherein the storage means stores time information together with the information signal, and when it is determined that the time specified by the time information has elapsed, the information stored in the storage means And an erasing means for erasing a signal. In this way, when the time information is compared with the reception time in the memory of the time information for each received message and it is determined that the fixed time set for each message has elapsed by counting the timer, the message after the fixed time has been automatically erased by the memory. Then, the trouble of erasing is released.

Further, as disclosed in Japanese Patent Application Laid-Open No. 04-220026, this radio selective calling receiver includes a time counting unit and a message storage unit, is activated by a power switch, and receives a reception time and a current time. And that when the time difference is greater than a predetermined specified time difference, the reception time and the stored content that the call has been received are deleted. Specifically, when the radio selective calling receiver is activated by the power switch unit, the current activation time is compared with the message reception time stored in the storage unit, and when a predetermined time has elapsed. There is a technology that automatically deletes the message.

[0005]

However, since the conventional radio selective call receiver cannot recognize whether the message is a personal message of the owner or an information message, it is necessary to periodically check the stock price information, weather information, and bank interest rate information. In the information receiving service, the old information messages that are no longer needed remain in the storage unit unless the owner deletes them as a result of storing them in the order in which they were received. When it becomes full, messages that are old but important to the owner may be deleted.

Further, for example, a stock price information message changes on a daily basis, a weather forecast and traffic information changes on a hourly basis, and an event information message is effective until the event ends. The update cycle desired by the owner differs depending on the type of the information message, so if the specified time elapses, the corresponding message will be deleted depending on the type of information message. The message may be deleted.
