Problems solved by technology

[0004] The above two existing methods need to rely on BMS / ITMS to issue time zone and daylight saving time information, and for the situation that the same country / region spans multiple time zones or multiple daylight saving time intervals, typical branch offices in the United States and Canada Different time zones, Spain is divided into different time zones and enters daylight saving time. At this time, BMS / ITMS needs to configure different time zones or daylight saving time for each user separately, which increases the synchronization workload in the process of synchronizing time zones or daylight saving time

Embodiment 1

[0081] The embodiment of the present invention provides a time synchronization method, such as figure 1 As shown, when applied to OLT (its English full name is Optical Line Terminal, is called for short Optical Line Terminal), described method comprises the following steps:

[0082] 101. According to the pre-configured NTP server information on the OLT, send a time synchronization request to the NTP server, so that the NTP server returns GMT time to the OLT.

[0083]When the OLT is connected to the network, the network manager will pre-configure the NTP server information and the time zone and daylight saving time information of the location of the OLT on the OLT. After the OLT accesses the network, it will send a time synchronization request to the NTP server according to the pre-configured NTP server information, and the NTP server will return the GMT time to the OLT after receiving the time synchronization request. It should be noted here that the OLT may send a time synch...

Embodiment 2

[0108] The embodiment of the present invention provides a time synchronization method, such as image 3 As shown, the method includes the following steps:

[0109] 301. The OLT sends a time synchronization request to the NTP server according to the NTP server information preconfigured on the OLT.

[0110] When the OLT is connected to the network, the network manager will pre-configure the NTP server information and the time zone and daylight saving time information of the location of the OLT on the OLT. After the OLT accesses the network, it will send a time synchronization request to the NTP server according to the pre-configured NTP server information. It should be noted here that the OLT may send a time synchronization request to the NTP server immediately after accessing the network, or may send a time synchronization request to the NTP server periodically at other times with a predetermined time as a cycle.

[0111] 302. After receiving the time synchronization request,...

Abstract

The embodiment of the invention provides a time synchronizing method and device, and relates to the field of communication. The time synchronizing method and device can solve the problem of difficult synchronization for time zones or daylight saving time. The time synchronizing method comprises the steps that an OLT sends a time synchronizing request to an NTP server according to pre-configured NTP server information to obtain the GMT, after registration and on-line are carried out on an ONU, a message carrying the information of the time zone and the daylight saving time, configured on the OLT in advance, of the location of the OLT and a message carrying the current GMT obtained in a calculating mode according to the GTM sent by the NTP server are sent to the ONU, and therefore the ONU obtains the local time in a calculating mode according to the received information of the time zone and the daylight saving time of the location of the OLT and the current GMT.

Description

technical field [0001] The present invention relates to the communication field, in particular to a time synchronization method and device. Background technique [0002] In the FTTH (full English name is Fiber To The Home, referred to as Fiber to the Home) networking, the user side equipment is based on the ONU (English full name is Optical Network Unit, referred to as Optical Network Unit) IP bearer voice service , the incoming call time and network time displayed on the user-side device must be synchronized with the local time, and the local time displayed on the user-side device can be obtained from the ONU. The ONU can calculate the local time according to GMT (the full English name is Greenwich Mean Time, referred to as Greenwich Mean Time), the time zone where the ONU is located, and the offset of daylight saving time. [0003] In the prior art, there is a method that can make the ONU synchronize to obtain the local time and send it to the user side equipment: a conne...
