PROBLEM TO BE SOLVED: To improve the time setting operability by adding a specific telephone number to a base station to transmit the clock data and also adding a means which dials the specific telephone number to transmit a sending request command of the clock data to a radio telephone set together with a means which sets the time of a clock based on the time of the clock data that is acquired from the base station. SOLUTION: When a clock setting function number is inputted from a key input part 10, a communication control means 22 dials a specific telephone number for sending the clock data on a base station via a transmitting/receiving part 30 and transmits the additional information together with a clock data request command, e.g. 'XX'. The base station generates the clock data consisting of 10 bytes including those showing the current year, month, day, hour, second and minute, a header, a checksum, etc., and transmits the clock data to a radio telephone set together with the additional information. A clock count means 24 of the telephone set sets the received time data as the current time and starts the clock of an outgoing circuit part 50.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio telephone with a clock, and more particularly to a radio telephone capable of automatically adjusting the time.

[0002]

2. Description of the Related Art In a conventional watch radio telephone, when adjusting the time of a clock, a user must adjust the time by operating a plurality of keys, which requires a complicated key operation. So, as a solution to this problem,
For example, JP-A-5-68075, JP-A-8-18
There is one proposed in Japanese Patent No. 6868. In the former telephone with a clock, a call is made to the time signal service of the exchange, and the time is corrected by the time signal sound transmitted from the exchange.

In the latter mobile communication system, the mobile phone and the base unit each correct the time of their own clocks based on time information sent from the public base station or the base unit, and The modification date and time are stored. In the wireless area of the public base station, the mobile phone corrects its own clock based on the time information from the public base station. If the date is newer than the date and time, the base unit corrects the time based on the time information of the base unit. If the correction date and time of the mobile phone is new, the base unit corrects the time of its own clock based on the time information of the mobile phone.

[0004]

In the former telephone with a clock, when setting the time, the time is simply corrected using the time signal. Therefore, the date and time when the time is to be set are input. The operation of setting the time is not always easy. In the latter mobile communication system, when setting the clock of the mobile phone for the first time,
It is necessary to set the mobile phone itself by key operation, which also puts a burden on the user.

The present invention has been made in view of the above-mentioned conventional problems, and has as its object to provide a wireless telephone with a clock that can easily adjust the time.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a base station for transmitting clock data when a clock setting is instructed in a wireless telephone having a clock for measuring time. Means for calling a predetermined telephone number of a station, means for transmitting a clock data request command to transmit clock data when connected to the predetermined telephone number of the base station, Means for setting the time of the clock to the time of the obtained clock data when the clock data is transmitted from the base station in response to the request.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of a wireless telephone with a clock according to the present invention. In FIG. 1, 10 is a key input unit including a plurality of keys such as a dial, 20 is a control unit for controlling each unit in the telephone, 30 is a transmitting and receiving unit that performs wireless transmission and reception of signals with a base station, Reference numeral 31 denotes a transmitting / receiving antenna. Numeral 40 is a display unit comprising a liquid crystal display panel, and 50 is an oscillation circuit unit for oscillating a clock for counting a clock.

The control unit 20 analyzes the function number input from the key input unit 10, and determines a function to be controlled by a function determining unit 21, and monitors a state of communication with the base station. Communication control means 22, data check means 23 for checking whether clock data sent from the base station is normally received, and when data check means 23 determines that clock data is normally received,
It comprises a clock counting means 24 for performing a clock operation.

Next, a specific operation of the present embodiment will be described with reference to FIG. In FIG. 2, first, the user operates the key input unit 10 to input a function number for clock setting. (S1). For example, the function number for clock setting is 11
(Hereinafter, referred to as F11). When the function number is input, the function determining means 21 compares the input function number with the function number for clock setting, and determines whether the function number is a function number for clock setting (S2). Here, if the input function number is F11 and is a function number for clock setting, the communication control means 22 controls the transmission / reception unit 30 to use a special telephone number for sending clock data of the base station. A call is made (S3).

On the other hand, when the input function number is not the function number for setting the clock, another processing corresponding to the input function number is performed (S13). Next, after calling the special telephone number, the communication control means 22 determines whether or not the connection to the special telephone number has been normally made (S4). If the connection is successful, the communication control unit 22 controls the transmitting / receiving unit 30 to transmit a clock data request command to the base station so as to transmit clock data (S5). When the connection fails due to a reason such as congestion of the line, the communication control unit 22 disconnects the line and ends the clock setting process. Upon receiving the clock data request command, the base station transmits clock data to the wireless telephone, and upon receiving the clock data, the communication control unit 22 determines whether reception of all clock data has been completed ( S
6).

FIG. 3 shows an operation sequence between the radio telephone and the base station in this case. In FIG. 3, first, a call is made to the special telephone number of the base station as described above, and if the connection is successful, a response is made from the base station. When there is a response, the communication control means 22 carries a clock data request command as shown in FIG. 4 on the additional information and transmits it to the base station.
The additional information is defined in RCR-STANDARD (digital mobile phone system standard issued by Radio System Development Center). When the base station receives the clock data request command, the base station transmits the additional information with the date and the current time data.

FIG. 5 shows a signal format in this case. FIG. 5 shows time data at 17:25:58 on October 10, 1996. Upon receiving all the clock data, the communication control unit 22 sends the additional information to the base station with information indicating completion of the reception of the clock data. Upon receiving this information, the base station disconnects the line and ends the transmission of the clock data. When there is no response from the base station or when the reception of the clock data fails, the communication control unit 22 disconnects the line as described above and ends the clock setting process.

Now, return to FIG. When the reception of all the clock data from the base station is completed in S6, the data check means 23 checks whether there is any error in the clock data (S7), and based on the result, determines whether the reception of the clock data was successful. It is determined whether it is (S8). If the clock data is broken or is not normal data, it is displayed on the display unit 40 that the acquisition of the clock data has failed (S12) to notify the user. If there is no error in the clock data, it means that the reception of the clock data has succeeded. Therefore, the data checking unit 23 transmits the clock data to the clock counting unit 24.

In the clock counting means 24, the obtained clock data is set as the current time.
Is started, and counting of the clock of the oscillation circuit unit 50 is started (S9). In this way, the time of the clock is accurately adjusted to the current time, and thereafter the clock operation is performed from that time. Further, the time data measured by the clock counting means 24 is sent to the display unit 40 and displayed on the display unit 40 (S10). This completes the clock settings. Then, the wireless telephone ends the call state (S11), and shifts to a call waiting state.

Next, another embodiment of the present invention will be described. FIG. 6 is a flowchart showing the operation of the present embodiment. The configuration of the present embodiment is substantially the same as that of FIG. However, in the present embodiment, the key input unit 10 of FIG.
Is provided with a dedicated key for clock setting. When this key is pressed, the control means 20 automatically sets the clock.

In FIG. 6, first, when a clock setting key of the key input unit 10 is depressed (S1), the communication control means 22 sends clock data of the base station similarly to the previous embodiment. (S2). Next, the communication control means 22 determines whether or not a connection can be made to the special telephone number of the base station (S3). If the connection cannot be made due to line congestion or the like, the display unit 40 displays the clock data. The failure is displayed (S4). Also,
The call state is ended (S5), and a transition is made to a standby state.

On the other hand, if it is possible to connect to the base station, a clock data request command is transmitted as in the previous embodiment (S
6). Further, in the present embodiment, assuming that clock data is not transmitted from the base station due to the state of radio waves, a timer until data reception starts is started (S5). The time of the timer is set to a predetermined time. Next, it is determined whether or not reception of clock data from the base station has been started (S8). Here, in S9, if the clock data has not been sent before the timer measures the predetermined time, the process proceeds to S4, where the display unit 40 displays that the acquisition of the clock data has failed, and in S5, the forced operation is performed. To end the call state.

That is, if the line requires a call charge, the call charge will be added if the user waits for the clock data to be sent. If not, terminate the call forcibly. On the other hand, if the clock data is sent from the base station before the timer is up, the communication control means 22 determines whether or not all the clock data has been received (S10). Then, the data check means 23 checks whether there is any error in the clock data (S11). Next, it is determined whether or not the reception of the clock data is successful based on the check result (S
12) If there is no error in the clock data, the call is terminated (S13).
4 to start the clock (S14).

That is, the clock counting means 24 sets the time of the clock data as the current time, activates the oscillation circuit unit 50, and counts the clock of the oscillation circuit unit 50 from the current time, thereby performing the clock operation. To start.
The time data of the clock counting means 24 is sent to the display unit 40 and displayed on the display unit 40. As described above, the time of the clock is accurately adjusted to the current time. If the received data is corrupted in S12, the communication control means 22 issues a clock data request command to the base station again, and performs the processing from S6.

[0020]

As described above, according to the present invention, when a clock setting is instructed, a call is made to the telephone number for transmitting the clock data of the base station, and the current time of the clock is transmitted from the base station. Since the time is set to the time of the clock data,
Simply enter a function number or press a special key for setting the clock without any complicated key operation, and simply and accurately set the clock time to the current time. There is an effect that can be.
