Embodiment 1

[0055] figure 1 A schematic diagram of a local time difference detection process between terminals provided in an embodiment of the present invention, the process includes the following steps:

[0056] S101: The terminal device plays sound information to the first terminal and the second terminal.

[0057] The method for detecting the local time difference between terminals provided by the embodiment of the present invention is applied to a terminal device, and the terminal device can play sound information. When the terminal device plays the sound information, the first terminal and the second terminal can identify and record the playing start time of the sound information. The sound information may be music stored in the terminal device, ringtones, recordings, or other sound information.

[0058] S102: Obtain a first play start time of the sound information recorded by the first terminal, and obtain a second play start time of the sound information recorded by the second t...

Embodiment 2

[0072] The terminal device may be a first terminal, may be a second terminal, or may be other devices independent of the first terminal and the second terminal.

[0073] When the terminal device is the first terminal, the first terminal plays the sound information, and detects the end point of the sound through the sound recognition module provided by itself, so as to identify whether the sound information starts, and when it recognizes that the sound information starts, record the recognition The local time corresponding to the start of the sound information is the recorded first playback start time. The second terminal detects the voice endpoint through the sound recognition module provided by itself, so as to identify whether the sound information starts. When the sound information is recognized At the beginning, record the corresponding local time when the start of the sound information is recognized, that is, record the second playback start time.

[0074] When the termin...

Embodiment 3

[0088] The terminal device plays sound information to the first terminal and the second terminal. The distance between the terminal device and the first terminal and the second terminal can be arbitrary. In order to enable the first terminal and the second terminal to accurately identify and record the terminal device The playback start time of the sound information to be played, based on the above embodiments, in the embodiment of the present invention, the first distance between the terminal device and the first terminal is within a preset distance range, and the terminal device The second distance from the second terminal is within a preset distance range. Preferably, the first distance and the second distance are equal.

[0089] The terminal device is any one of the first terminal and the second terminal, or is another device independent of the first terminal and the second terminal. When the terminal device is any one of the first terminal and the second terminal, the di...

Abstract

The embodiment of the invention discloses a delay detection method, apparatus and system, and a local time difference detection method, apparatus and system between terminals, in order to solve the following problem in the prior art: the synchronous calibration of local times of two terminals is inaccurate, such that the delay corresponding to a message cannot be accurately detected. The method comprises the following steps: playing sound information; obtaining a first playing start time of the sound information recorded by a first terminal, and obtaining a second playing start time of the sound information recorded by a second terminal; and determining a local time difference between the first terminal and the second terminal according to the first playing start time and the second playing start time. As the local time difference between the first terminal and the second terminal can be accurately determined according to the first playing start time of the sound information recorded by the first terminal and the second playing start time of the sound information recorded by the second terminal, when a message is received and sent between the terminals, the delay corresponding to the message is accurately determined.

Description

technical field [0001] The invention relates to the technical field of data services, in particular to a time delay and local time difference detection method, device and system between terminals. Background technique [0002] At present, it is more and more common for people to communicate by sending messages through the network. When a user uses one terminal to send a message to another terminal, there will generally be a time difference between sending and receiving, which is called delay. If the current network quality is good, the delay will be relatively short, and if the current network quality is poor, the delay will be longer, so the delay can be used as an evaluation index to measure the current network quality. [0003] At present, when detecting the time delay caused by one terminal (message sending end) sending a message to another terminal (message receiving end) receiving the message, it is often detected by manual dial testing and dial testing tools. of. ...
