Embodiment 1

[0079] Embodiment 1, instant time correction method

[0080] The terminal device sends a short message with the target terminal device number consistent with the terminal device number, and records the time information of the current terminal device at the sending time. The message is forwarded back to the terminal device, and at the same time, the time information of the current network-side message processing device is added to the message. After the terminal device receives the short message returned by the network side, it records the time information of the current terminal device at the receiving time, and obtains the time information forwarded by the network side from the short message, and then immediately performs the time correction process according to the correlation between the above time information. In this way, the terminal equipment only needs to realize the automatic time correction function through a short message. In the present invention, the short message...

Embodiment 2

[0090] Embodiment 2, random timing method

[0091] During the use of the terminal equipment, due to the frequency deviation of the internal crystal, the drop of the terminal equipment, the long-term battery failure, etc., there may be a deviation between the clock time of the terminal equipment and the standard time. In order to compensate for the deviation caused by the above reasons, this The invention also provides a method for randomly adjusting the time by using the receiving time and forwarding time of ordinary short messages. This method can be used alone or in conjunction with the first embodiment.

[0092] The random time calibration method can be executed when each text message is received, that is, when the terminal device receives a text message, it obtains the receiving time and forwarding time of the text message and calculates the deviation value of the local time relative to the standard time when the text message is received: The time is added to the one-way t...

Embodiment 3

[0113] Embodiment 3: Terminal Equipment with Instant Time Calibration Function

[0114] In order to realize the instant correction method described in the present invention, a terminal device with instant time correction function is also provided, such as image 3 As shown, the terminal equipment described in the present invention includes a short message processing module and a real clock chip connected to the short message processing module, wherein the short message processing module is used to send and receive short messages and process short messages, and the real clock chip includes the second pulse generated according to the crystal oscillator. Timing counter, the count value of the counter is stored in the corresponding storage unit;

[0115] The terminal equipment also includes: a timing module connected between the short message processing module and the real clock chip; wherein:

[0116] Described time school module triggers short message processing module to send ...

Abstract

The present invention relates to communication technology, specially relating to correcting terminal unit local zone time method and terminal unit. Said invented method includes 1, instant timing method utilizing special timing message transmission time, time of reception and retransmission time to make accuracy timing; 2, random timing method utilizing one message or continuously received at least two message receiving time and retransmission time to make compensating timing; said invention also providing terminal unit for realizing above-mentioned one or all method. Said method can be realized in terminal side without any change to network side.

Description

technical field [0001] The invention relates to communication technology, in particular to a method for correcting the local time of terminal equipment and the terminal equipment. Background technique [0002] As one of the most commonly used terminal devices, mobile phones have become very convenient communication tools in today's life. The clock function on the mobile phone has also become the most convenient way for people to keep track of the time. However, most of the mobile phones on the market do not have the function of automatic time adjustment. More cumbersome. During the use of the mobile phone, there may be a time difference between the time on the mobile phone and the standard time due to the frequency deviation of the internal crystal, the drop of the mobile phone, and the battery being out of power for a long time. At this time, the user needs to reset the timing. Usually, it is no problem to manually modify the time of the mobile phone using TV and broadcas...
