Problems solved by technology

In the current mobile network, when the terminal communicates with the base station equipment, the uplink and downlink synchronization is based on the relative time synchronization based on the wireless frame / subframe boundary alignment, and cannot perform absolute time timing.
However, if the traditional network time protocol (NTP protocol) or PTP protocol is directly used in the mobile network, it is affected by factors such as the instability of the air interface link, resulting in a decline in its timing performance.

Abstract

The embodiment of the present disclosure discloses a timing method, device and readable storage medium for a mobile network. The mobile network includes: a first clock, a first network, a first network device, and a second network device. The first network device obtains timing information from the first clock through the first network; calibrates the second network device clock of the second network device according to the timing information; and calibrates the terminal clock of the terminal device according to the calibrated second network device clock.

Description

technical field [0001] The present disclosure relates to the technical field of wireless communication, and in particular, to a timing method, a device and a readable storage medium for a mobile network. Background technique [0002] In the communication network, timing has a very important basic role. In the wired optical network, according to the high-precision timing protocol (PTP protocol) proposed by the IEEE1588v2 standard, the timing accuracy of the order of 10ns can be achieved by using the symmetry of the link. However, in the current mobile network, when the terminal communicates with the base station equipment, the uplink and downlink synchronization is based on the relative time synchronization of radio frame / subframe boundary alignment, and absolute time timing cannot be performed. However, in the mobile network, the traditional network time protocol (NTP protocol) or the PTP protocol is directly used, which is affected by factors such as the instability of the...
