[0044] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0049] Figure 4 is a block diagram of an electronic device according to an exemplary embodiment. DETAILED DESCRIPTION

[0050] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] First, the application scenario of the present disclosure is described. The present disclosure can be applied to the time update scenario of the terminal. The time module of the terminal is a very important function. In practical applications, if the time information of the terminal is inaccurate, the user's alarm clock or QR code payment service will not be able to be used normally. Among them, the QR code payment service of the smart terminal is widely used in urban public transportation such as subways, buses, ferries and daily consumption in urban life. QR code payment is a new type of mobile payment technology that generates consumption QR codes through smart terminals, scans and identifies the codes through fixed or mobile smart terminals, and performs QR code consumption. In order to improve security, some application servers that scan QR codes will verify the time when the terminal generates the QR code. For example, some applications require that the QR code is valid within one minute after generation. The validity of the QR code is judged by comparing the generation time of the QR code with the current time of the application server, which also puts higher requirements on the accuracy of the terminal time. If the time information of the terminal is inaccurate, the QR code verification will fail, resulting in the user's QR code payment service being unable to be used normally.

[0052] It should be noted that the terminal in the present disclosure may be an electronic device such as a smart phone, a tablet computer, a smart watch, a smart bracelet, a PDA (Personal Digital Assistant), a CPE (Customer Premise Equipment), etc., and the present disclosure does not limit this.

[0053] The sources of terminal time information can include the following:

[0054] 1. Network device time information from network devices, also known as NITZ (Network Identity and Time Zone), is a mechanism that provides local date and time, time zone, daylight saving time, and network provider identity information to terminals through wireless networks, which is usually used for mobile terminals to automatically update system time. For example, the network device time information may be time information sent to the terminal by a base station or core network, and the network device time information may have information such as time zone and daylight saving time, but the time accuracy is low, for example, generally minute-level accuracy.

[0055] Second, the server time information from the time server can also be called NTP (Network Time Protocol) time. NTP is a protocol used to synchronize computer time. First, the time source of NTP is the international standard time UTC. The time server can obtain the international standard time through atomic clocks, observatories or satellites. The time server can send the server time information to the terminal. The time accuracy of the server time information is high, for example, it can reach millisecond-level accuracy, but the server time information does not contain information such as time zone and daylight saving time.

[0056] 3. Real-time clock time information from the terminal's real-time clock (RTC). The terminal's real-time clock requires hardware support, relies on the terminal's high-precision crystal oscillator, and requires the user to manually set the initial time when the terminal is first run.

[0057] In the related art, the terminal uses the above network device time information as the highest priority time source. When receiving the network device time information, the terminal can directly use the network device time information as the current time information of the terminal. However, due to the development of communication technology, such as the gradual promotion and testing of 5G and 6G, network equipment is updated or adjusted more frequently, and network device time errors may occur due to network equipment adjustments or human misoperation. At this time, if the terminal still uses the wrong network device time information as the current time information of the terminal, it will cause terminal time errors, which will also affect the normal use of users.

[0058] In order to solve the above problems, the present disclosure provides a time update method, device, storage medium and electronic device, which generate anchor time information through candidate time information of multiple time sources, and continuously update the current time information of the terminal according to the anchor time information. When receiving the network time information sent by the network device, it can determine whether the network device time information is reliable according to the first time offset between the network device time information and the current time information of the terminal. When the network device time information is reliable (that is, the first time offset is within the preset first offset range), the anchor time information of the terminal is updated according to the network device time information. In this way, the problem of terminal time error caused by network device time error can be avoided, thereby improving the accuracy of terminal time.

[0059] The present disclosure is described below in conjunction with specific embodiments.

[0060] Figure 1 is a time updating method provided by an embodiment of the present disclosure, such as Figure 1 As shown, the execution subject of the method may be a terminal, and the method may include:

[0061] S101. Receive network device time information sent by a network device.

[0062] By way of example, the network device may be a base station or a core network in a wireless communication network; the network device time information may be time information obtained by the network device through satellite systems such as GPS and Beidou; it may also be time information obtained by the network device through a time server (such as an NTP server); of course, it may also be time information obtained based on the network device's own crystal oscillator and configuration.

[0063] It should be noted that the network device can send the network device time information to the terminal when the terminal initiates network registration at the network device. In this way, the terminal can initiate network registration periodically or when it moves to the boundary between two network devices, thereby triggering the network device to send the network device time information.

[0064] Furthermore, in order to obtain network device time information more quickly, the terminal can also actively send a time request message or a registration request message to the network device in addition to normal network registration, when determining that the network device time needs to be obtained, so that the network device sends the network device time information to the terminal according to the time request message or the registration request message. For example, the terminal can periodically send a time request message to the network device, thereby triggering the network device to periodically send the network device time information to the terminal. The period for sending the time request message can be any time period pre-set between 1 minute and 10080 minutes, for example, 60 minutes or 1440 minutes. In this way, the terminal can obtain the network device time information in a timely manner, so as to update the anchor time information of the terminal according to the network device time.

[0065] S102: Obtain a first time offset between the network device time information and the current time information of the terminal.

[0066] The current time information is the current time obtained based on the anchor time information of the terminal, and the anchor time information is the time information obtained based on candidate time information of multiple time sources.

[0067] It should be noted that the anchor time information can be obtained by mutual calibration of the candidate time information of the above-mentioned multiple time sources of the terminal. The accuracy of the anchor time information can be improved by mutual calibration of the candidate time information of multiple time sources. The mutual calibration method can be to calibrate according to the time difference of multiple time sources. For example, when the absolute value of the time difference between multiple candidate time information is less than or equal to the preset time difference, it can be considered that the multiple candidate time information meet the time accuracy. At this time, the candidate time information of the time source with the highest priority can be selected as the anchor time information; or, according to the preset first time weighting coefficient of each time source, the candidate time information corresponding to multiple time sources can be calculated by weighted averaging to obtain the anchor time information.

[0068] Further, in the case of acquiring the anchor point time information, the anchor point time information can be used as the current time information of the terminal, and the current time information of the terminal can be updated according to the anchor point time information and the crystal oscillator time of the terminal. For example, at the moment of acquiring the anchor point time information, a time timer can be started according to the crystal oscillator time of the terminal, and the first duration from acquiring the anchor point time information to the current time can be obtained through the time timer, and the current time information of the terminal can be acquired according to the anchor point time information and the first duration.

[0069] In this step, the difference between the network device time information and the current time information of the terminal can be used as the first time offset; or the absolute value of the difference between the network device time information and the current time information of the terminal can be used as the first time offset.

[0070] S103: When the first time offset is within a preset first offset range, update the anchor point time information of the terminal according to the network device time information.

[0071] In the case where the difference between the network device time information and the current time information of the terminal is used as the first time offset, the preset first offset range may be a range between a preset first minimum value and a preset first maximum value, the preset first minimum value may be a negative value, and the preset first maximum value may be a positive value. For example, the preset first offset range may be a range greater than or equal to -60 seconds and less than or equal to +60 seconds.

[0072] When the absolute value of the difference between the network device time information and the current time information of the terminal is used as the first time offset, the preset first offset range may be a range from 0 to a preset first maximum value. For example, the preset first offset range is a range greater than or equal to 0 and less than or equal to 60 seconds.

[0073] It should be noted that if the first time deviation is within the preset first offset range, it can be determined that the above network device time information is reliable time information. Therefore, the anchor point time information of the terminal can be updated according to the network device time information in any of the following ways:

[0074] Method 1: The network device time information can be used as the updated anchor point time information.

[0075] Method 2: The updated anchor point time information can be calculated based on the network device time information and the current time information of the terminal by weighted averaging.

[0076] For example, the updated anchor point time information can be calculated by the following formula:

[0077] Tm=T1*W1+T2*W2,

[0078] Among them, Tm represents the updated anchor point time information, T1 represents the network device time information, W1 represents the first preset weight corresponding to the network device time information, T2 represents the current time information of the terminal, and W2 represents the second preset weight corresponding to the current time information.

[0079] The above method is adopted to obtain the first time offset between the network device time information and the current time information of the terminal by receiving the network device time information sent by the network device, the current time information is based on the anchor time information of the terminal, and the anchor time information is the time information obtained according to the candidate time information of multiple time sources; when the first time offset is within the preset first offset range, the anchor time information of the terminal is updated according to the network device time information. In this way, the reliability of the network device time information is verified by the anchor time information obtained by multiple time sources, and when it is determined that the received network device time information is reliable, the network device time information is used again, which can avoid the terminal time error problem caused by the network device time error, improve the accuracy of the terminal time, and ensure that the related functions that rely on the terminal time can be used normally.

[0080] Further, in a case where the first time offset exceeds the preset first offset range, the anchor point time information of the terminal may be kept unchanged.

[0081] It should be noted that if the first time deviation exceeds the preset first offset range, it can be determined that the above network device time information is unreliable. At this time, the network device time information can be ignored and the anchor time information of the terminal can be kept unchanged. And the current time information of the terminal can continue to be obtained based on the anchor time information and the crystal oscillator time of the terminal. Since the crystal oscillator of the terminal can maintain a certain accuracy rate for a long time, for example, the time deviation rate of the active crystal oscillator used by the terminal can be less than or equal to 10ppm, that is, the time deviation of the crystal oscillator running 24 hours a day is less than or equal to 0.864 seconds. Therefore, when it is judged that the above network device time is unreliable, the anchor time information and the crystal oscillator time of the terminal can be used to obtain more accurate current time information.

[0082] In this way, the problem of terminal time error caused by the terminal using unreliable network device time information can be avoided, thereby ensuring that related functions that rely on terminal time can be used normally.

[0083] In another embodiment of the present disclosure, the network device time information includes the network device time and the network device time zone, and the current time information includes the current time and the current time zone; the step S102 of acquiring the first time offset between the network device time information and the current time information may include the following steps:

[0084] First, determine whether the time zone of the network device is the same as the current time zone of the terminal.

[0085] It should be noted that the network device time zone may be the time zone corresponding to the region where the network device is located, such as the time zone obtained by the network device through a time server in the region; or, the network device time zone may be the time zone corresponding to the time zone parameters configured on the network device, and the time zone parameters may be parameters manually configured by the user.

[0086] The current time zone of the terminal may be a time zone acquired according to the anchor point time information.

[0087] Then, when the network device time zone is the same as the current time zone of the terminal, the difference between the network device time and the current time is used as the first time offset; or, the absolute value of the difference between the network device time and the current time is used as the first time offset.

[0088] In this way, by comparing the network device time zone with the current time zone of the terminal, that is, the time zone of the terminal has not changed, the first time offset between the network device time and the current time can be obtained, and based on the first time offset, it can be determined whether the anchor point time information of the terminal can be updated according to the network device time information.

[0089] Furthermore, when the network device time zone is different from the current time zone of the terminal, candidate time information of multiple time sources is reacquired; new anchor time information is obtained based on the candidate time information of multiple time sources; and the current time information of the terminal is updated based on the new anchor time information.

[0090] It should be noted that the time zone of the network device is different from the current time zone of the terminal, which means that the terminal has moved across time zones. At this time, the original anchor point time information is no longer reliable and new anchor point time information needs to be re-acquired to avoid the problem of terminal time errors caused by continuing to use the original anchor point time information.

[0091] In another embodiment of the present disclosure, the anchor point time information may be obtained in the following manner:

[0092] First, two candidate time sources are determined from multiple time sources, and candidate time information corresponding to the candidate time sources is obtained.

[0093] In this step, two candidate time sources can be randomly determined from multiple time sources; or the two time sources that first receive time information can be determined as candidate time sources based on the order in which the time information of the time sources is received; or two candidate time sources can be determined from multiple time sources based on a pre-set time source priority and the current status of the time source, and the current status of the time source can indicate whether the terminal has received the time information sent by the time source.

[0094] For example: if the above-mentioned multiple time sources include: a network device time source, a time server time source, and a terminal real-time clock time source, the time source priorities corresponding to the multiple time sources can be pre-set as: network device time source priority>time server time source>terminal real-time clock time source. In this way, when the current status of the above-mentioned multiple time sources is the time information received from the time source, according to the above-mentioned time source priority, the network device time source and the time server time source can be used as candidate time sources, and the network device time information received from the network device and the server time information received from the time server can be used as candidate time information.

[0095] Furthermore, if the current status of the time server time source is that the time information of the time source has not been received, and the current status of the network device time source and the terminal real-time clock time source are both that the time information of the time source has been received, then the network device time source and the terminal real-time clock time source can be used as candidate time sources, and the network device time information received from the network device and the real-time clock time information obtained from the terminal real-time clock can be used as candidate time information.

[0096] Secondly, obtain the second time offsets of the two candidate time information.

[0097] Finally, when the second time offset is within the preset second offset range, the anchor point time information is acquired according to the two candidate time information.

[0098] Similarly, in this embodiment, the difference between the two candidate time information can be used as the second time offset; the preset second offset range is preset to a range between a preset second minimum value and a preset second maximum value, the preset second minimum value can be a negative value, and the preset second maximum value can be a positive value. For example, the preset first offset range can be a range greater than or equal to -120 seconds and less than or equal to +120 seconds.

[0099] In addition, the absolute value of the difference between the two candidate time information may be used as the second time offset; the preset first offset range is preset to a range from 0 to a preset second maximum value. For example, the preset first offset range is a range greater than or equal to 0 and less than or equal to 120 seconds.

[0100] In this way, by mutually verifying the candidate time information obtained from multiple time sources, accurate anchor point time information can be obtained, and further accurate terminal current time information can be obtained based on the anchor point time information, which can avoid errors in terminal time and improve the accuracy of terminal time.

[0101] In another embodiment of the present disclosure, the candidate time information may include server time information and network device time information, the server time information includes a first server time corresponding to a preset time zone, and the network device time information includes a network device time and a network device time zone; thus, the second time offset of the two candidate time information may be obtained in the following manner:

[0102] According to the first server time, the preset time zone and the network device time zone, the second server time corresponding to the network device time zone is calculated; the difference between the network device time and the second server time is used as the second time offset, or the absolute value of the difference between the network device time and the second server time is used as the second time offset.

[0103] For example, the above-mentioned preset time zone can be the zero time zone, that is, the Greenwich time zone of the United Kingdom, and the network device time zone can be set according to the region where the network device is located. For example, the network device time zone of a network device located in China can be East 8 Zone. In this way, the first server time can be increased by 8 hours to obtain the second server time.

[0104] In this way, the first server time corresponding to the preset time zone can be converted into the second server time corresponding to the network device time zone, so that the accurate time offset between the server time and the network device time can be obtained.

[0105] Furthermore, the above-mentioned anchor point time information includes anchor point time and anchor point time zone. Thus, when the second time offset is within a preset second offset range, the step of obtaining the anchor point time information based on the two candidate time information may include: using the second server time as the anchor point time; and using the network device time zone as the anchor point time zone.

[0106] It should be noted that the server time has a high accuracy, which can reach millisecond level, but the server time information does not contain time zone information. Therefore, through this method, the server time and the network device time zone are combined to obtain accurate anchor point time information, thereby improving the accuracy of terminal time.

[0107] It should also be noted that some regions also use the daylight saving time function, and the above-mentioned network device time information, the current time information of the terminal, and the anchor time information can all include the daylight saving time information. The daylight saving time information in the network device time information can be determined based on the daylight saving time information of the region where the network device is located, or can be determined based on the daylight saving time configuration parameters of the network device. The terminal can use the daylight saving time information in the received network device information as the daylight saving time information in the current time information and the anchor time information.

[0108] In this way, the accuracy of terminal time can be ensured even when daylight saving time is in effect.
