Embodiment 1

[0042] The embodiment of the present invention proposes an information synchronization method, such as figure 1 shown, including:

[0043] Step 101: Collect at least two business processes;

[0044] Step 102: From the at least two business processes, select the business process of the first electronic device that meets the first preset condition and the network-side business process corresponding to the first electronic device;

[0045] Step 103: When the time information of the first business process of the first electronic device is different from the time information of the first business process on the network side corresponding to the first electronic device, determine a first time offset;

[0046] Step 104: Using the first time offset, adjust the time information of the data information in the business process of the first electronic device.

[0047] Here, the implementation device of this embodiment may be a network device that can be connected to multiple interfaces ...

specific Embodiment approach

[0072] Scenario 1, such as Figure 4 As shown, the time information TB0 of the first business process on the network side corresponding to the first electronic device is greater than the time information TA0 of the first business process of the first electronic device, then the time difference of the uplink data of the first electronic device The value (UpValue) is equal to TA0 minus TB0; the time information TB1 of the second business process on the network side corresponding to the first electronic device is also greater than the time information TA1 of the second business process of the first electronic device, then the first electronic The time difference (DownValue) of the downlink data of the device is equal to TA1 minus TB1;

[0073] If the time of the service process of the first electronic device and the time information of the network-side service process corresponding to the first electronic device are adjusted according to the maximum value (UpValueMax) of the upli...

Embodiment 2

[0089] The embodiment of the present invention proposes a network device, such as Image 6 As shown, the network equipment includes:

[0090] A collection unit 61, configured to collect at least two business processes;

[0091] The selecting unit 62 is configured to select, from the at least two business processes, the business process of the first electronic device that meets the first preset condition and the network-side business process corresponding to the first electronic device;

[0092] A calculation unit 63, configured to determine a first time offset when the time information of the first business process of the first electronic device is different from the time information of the first business process on the network side corresponding to the first electronic device quantity;

[0093] The processing unit 64 is configured to use the first time offset to adjust the time information of the data information in the business process of the first electronic device.

Abstract

The invention discloses an information synchronization method and a piece of network equipment. The method comprises the following steps: collecting at least two business processes; selecting business processes of first electronic equipment in accordance with a first preset condition and network-side business processes corresponding to the first electronic equipment from the at least two business processes; determining a first time offset when the time information of the first business process of the first electronic equipment is different from the time information of the network-side first business process corresponding to the first electronic equipment; and adjusting the time information of the data information in the business processes of the first electronic equipment based on the first time offset.

Description

technical field [0001] The invention relates to a communication network synchronization technology, in particular to an information synchronization method and network equipment. Background technique [0002] The time synchronization technology includes a GPS (Global Positioning System) synchronization method based on satellite data and a Network Time Protocol (NTP, Network Time Protocol) synchronization method based on a network protocol. However, the above two GPS / NTP synchronization methods cannot eliminate the time error of the final data information due to the difference in the operating system and application program performance of the acquisition device during the data acquisition process. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide an information synchronization method and network equipment, which can at least solve the above-mentioned problems existing in the prior art. [0004] In order to achieve the abo...
