A WAN interface based packet reception method within the IEEE 1588V2 standard, the method comprising: receiving, by a receiving end, a data frame that is sent by a sending end and carries a packet (step 401); acquiring, by the receiving end, a receiving time at which the data frame is received (step 402); performing, by the receiving end, time synchronization adjustment on the receiving time (step 408), and before the step of performing, by the receiving end, time synchronization adjustment on the receiving time, further comprising: configuring, by the receiving end, a synchronous counter separately for a wide area network interface sublayer, WIS, and a media access control, MAC, sublayer (step 403); when the data frame carrying the packet is transmitted to the WIS, acquiring, by the receiving end, a first count value corresponding to the WIS (step 404); and when the data frame carrying the packet is transmitted to the MAC sublayer, acquiring, by the receiving end, a second count value corresponding to the MAC sublayer (step 405), wherein the step of performing, by the receiving end, time synchronization adjustment on the receiving time comprises: performing, by the receiving end, the time synchronization adjustment on the receiving time according to a count difference between the first count value and the second count value, wherein the receiving time is a corresponding time at which the data frame carrying the packet is transmitted to the MAC sublayer. receiving, by a receiving end, a data frame that is sent by a sending end and carries a packet (step 401); acquiring, by the receiving end, a receiving time at which the data frame is received (step 402); performing, by the receiving end, time synchronization adjustment on the receiving time (step 408), and before the step of performing, by the receiving end, time synchronization adjustment on the receiving time, further comprising: configuring, by the receiving end, a synchronous counter separately for a wide area network interface sublayer, WIS, and a media access control, MAC, sublayer (step 403); when the data frame carrying the packet is transmitted to the WIS, acquiring, by the receiving end, a first count value corresponding to the WIS (step 404); and when the data frame carrying the packet is transmitted to the MAC sublayer, acquiring, by the receiving end, a second count value corresponding to the MAC sublayer (step 405), wherein configuring, by the receiving end, a synchronous counter separately for a wide area network interface sublayer, WIS, and a media access control, MAC, sublayer (step 403); when the data frame carrying the packet is transmitted to the WIS, acquiring, by the receiving end, a first count value corresponding to the WIS (step 404); and when the data frame carrying the packet is transmitted to the MAC sublayer, acquiring, by the receiving end, a second count value corresponding to the MAC sublayer (step 405), wherein the step of performing, by the receiving end, time synchronization adjustment on the receiving time comprises: performing, by the receiving end, the time synchronization adjustment on the receiving time according to a count difference between the first count value and the second count value, wherein the receiving time is a corresponding time at which the data frame carrying the packet is transmitted to the MAC sublayer. performing, by the receiving end, the time synchronization adjustment on the receiving time according to a count difference between the first count value and the second count value, wherein the receiving time is a corresponding time at which the data frame carrying the packet is transmitted to the MAC sublayer.
