Kind Code:
A1
Abstract:
The embodiments of the present invention relate to the field of internet of things technology, and disclose a time synchronization method and system for an internet of things terminal device and a convergence unit. The method comprises: an internet of things access point sending, within the wireless network coverage thereof, a broadcast message comprising a first time label, and receiving a response message, sent by the terminal device, the response message comprising the type of the terminal device, the first time label, a second time label concerning the terminal device receiving the broadcast message and a third time label concerning the terminal device sending the response message, determining whether the type of the terminal device matches the device type specified by the convergence unit, and if so, obtaining, according to the first time label, the second time label, the third time label and a fourth time label concerning the reception of the response message, a time difference between the internet of things access point and the terminal device and sending same to the terminal device; and the terminal device performing time synchronization adjustment according to the time difference, for synchronizing the internet of things terminal device and the convergence unit.
