Problems solved by technology

However, at present, there are situations in which the synchronization protocol is not supported in the established network environment, resulting in the inability to realize the network time synchronization function. If the equipment is replaced for this purpose, no matter which party is disadvantaged, it will also increase the operation of the operator virtually. cost

Embodiment Construction

[0015] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0016] figure 1 is a flowchart of a time synchronization method according to an embodiment of the present invention. Such as figure 1 As shown, the time synchronization method according to the embodiment of the present invention includes:

[0017] Step S102, the terminal sends a time synchronization short message to itself through the network side;

[0018] Step S104, the terminal receives the time synchronization short message sent by itself and parses out the time stamp information in the time synchronization short message;

[0019] Step S106, the terminal determines the synchronization time according to the above timestamp information.

[0020] In order to shield the influence of the network ...

Abstract

The invention discloses a time synchronization method and an apparatus thereof. The method comprises the following steps: a terminal sends a time synchronization short message to the terminal itself through network-side; the terminal receives the time synchronization short message sent by the terminal and parses the time stamp information in the time synchronization short message; the terminal determines the synchronization time according to the above time stamp information. According to the technical scheme provided in the invention, the problem that the time synchronization function can not be realized since that an established mobile communication network does not support synchronization protocol is solved, thus the time synchronization function is realized in the case that the network equipment does not support the function.

Description

technical field [0001] The present invention relates to the communication field, in particular to a time synchronization method and device. Background technique [0002] With the development of communication technology, people have more and more powerful requirements for the functions of mobile terminals, and the network time synchronization function has emerged as the times require. Time synchronization refers to the synchronization of the time and time interval of the clocks of each node in the network and the clocks of each application interface connected through the network with GMT (Greenwich Mean Time, Greenwich Mean Time, or Greenwich Mean Time), at least nationwide. Beijing time synchronization. [0003] The basic function of IEEE 1588 is to synchronize the most accurate clock in the distributed network with other clocks. It defines a PTP (Precision Time Protocol, Precision Time Protocol) for standard Ethernet or other distributed networks using multicast technology...
