Abstract

PURPOSE: A method for managing a time reservation in a digital cellular phone is provided to perform a management reservation and a power on/off management efficiently by calculate a present time on the basis of a system time information. CONSTITUTION: When a user inputs a personal schedule information through a key pad(15), the personal schedule information is stored at a memory(13). At this time, the user selects an output mode of the personal schedule information. The output mode includes an output through an LCD(14) and an output through a speaker(16). After this, a present time measuring part(11) checks whether a present time is accorded with a reservation time stored at the memory(13) or not. At this time, present time is calculated by means of a system time of a data processor(10). When the present time is accorded with a reservation time, the memory(13) outputs the personal schedule information through the LCD(14) or the speaker(16).

The present invention relates to a digital cell phone, and more particularly, to a digital cell phone time reservation management method for efficiently performing personal schedule management and power on / off management.

Conventional analog cell phones store programs necessary for performing unique functions and manage a phone number, a person's name, an address, etc. input by an alphanumeric key using the remaining memory. In addition, the conventional analog cell phone turns off the power after a certain time after the call ends when performing the automatic on / off function.

The analog cell phone provides only fixed information such as a person's name, phone number, address, etc., but can not manage the reservation according to the time such as outputting an alarm sound at the appointment time. There is a problem that can not effectively reduce the battery consumption because there is no function to turn off the power at the scheduled time.

Disclosure of Invention The present invention has been made to solve the above problems, and an object of the present invention is to provide a method for managing time reservation of a digital cellular phone that efficiently manages power on / off and simultaneously manages reservation according to a specified time. have.

A feature of the present invention for achieving the above object is a digital cell phone, comprising: storing personal schedule information including a reservation time and reservation information; Receiving a sync channel message provided from a CDMA cellular system, extracting a system time, and estimating a current time using the system time; And if the current time coincides with the reservation time of the personal schedule information, displaying the stored reservation information and outputting an alarm signal.

Another feature of the invention is a digital cell phone, comprising: storing a power down time; Receiving a sync channel message provided from a CDMA cellular system, extracting a system time, and estimating a current time using the system time; And shutting off the power when the current time coincides with the power off time.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a time reservation circuit of a digital cellular phone according to a first embodiment of the present invention, and FIG. 2 is a block diagram of a time reservation circuit of a digital cellular phone according to a second embodiment of the present invention.

Code Division Mulitiple Access (CDMA) system, which is attracting attention as the next generation digital cellular system, informs each cell phone of system time through synchronous channel message. Send. This time information is transmitted in binary form from the elapsed time from GPS time (January 6, 1980 0: 0: 0 second) to the present invention. The present invention provides a time reservation using GPS time for a CDMA cellular phone. It was configured to be.

As shown in FIG. 1, the time reservation circuit of the digital cellular phone according to the first embodiment includes a data processor 10, a current time measuring unit 11, an input / output unit 12, a memory 13, and an LCD. 14, the keypad 15 and the speaker 16 are provided. The data processor 10 reads the system time information from the sync channel message supplied from the receiver, and outputs the system time information to the current time measuring unit ll. The current time measuring unit 11 estimates the current time using the system time information, and outputs an address to the memory 13 when the estimated current time coincides with the time reserved by the user in the memory 13. The memory 13 stores personal schedule information supplied from the keypad 15 through the input / output unit 12, and when an address is supplied from the current time measuring unit 11, the personal schedule information stored at the address is stored. It outputs to the LCD 14 side through the input / output unit 12 and outputs an alarm signal to the speaker 16 side.

When a user inputs personal schedule information for a predetermined period of time through the keypad 15, it is stored in the storage area of the memory 13. At this time, the user selects an option for specifying whether to display personal schedule information on the LCD 14 or output a ring to the speaker 16 when the reservation time comes. Then, the current time measuring unit 11 returns the corresponding personal schedule to the memory 13 side when the current time estimated by the system time from the data processor 10 coincides with the reservation time of the personal schedule information stored in the memory 13. Outputs an address for outputting information. At this time, the memory 13 outputs personal schedule information stored in a storage area corresponding to the supplied address, and outputs personal schedule information to the LCD 14 side or a ring signal to the speaker 16 according to the selected option. Outputs Accordingly, the user effectively manages his schedule.

As shown in FIG. 2, the time reservation circuit of the digital key phone system according to the second embodiment includes a data processor 20, a current time detector 21, a switch controller 22, a memory 23, and an input / output unit. (24). It comprises an LCD 25 and a keypad 26. The data processor 27 reads the system time information from the synchronization channel message supplied from the receiver, and outputs the system time information to the current time detector 21. The current time detector 21 detects the current time using the system time information, and outputs a control signal to the switch controller 22 when the detected current time matches the time reserved by the user in the memory 23. The switch controller 22 turns off the switch swl according to the control signal supplied from the current time detector 21 to cut off the power.

After the user has stored the power-off time in the memory 23 using the keypad 26, the current time detected by the system time from the data processor 20 is stored in the memory 23 by the current time detector 21. In accordance with the power off reservation time stored in the control unit 22 outputs a control signal to the switch control unit 22 to turn off the switch (swl) to cut off the battery power.

The present time measuring unit 11 and the present time detecting unit 21 of FIGS. 1 and 2 may calculate the present time entirely using system time information, and set the time when the cellular phone is purchased, and set the system time information and setting. You can also calculate the current time using the time difference.

As described above, the present invention calculates the current time using the system time information in the CDMA cellular system, thereby efficiently performing power on / off management and reservation management according to a specified time.
