Abstract

The embodiment of the invention discloses a clock processing method and apparatus, and PTP (Precision Timing Protocol) equipment. The clock processing method includes the steps: calculating time deviation according to an extracted time stamp; and correcting a system clock of a slave device through the time deviation, and correcting the extracted time stamp. The clock processing method and apparatus can solve the problem that an existing 1588 clock synchronization technology cannot satisfy the requirement of an ITU-TG. 8273.2 standard for the clock synchronization performance.

Description

technical field [0001] The present invention relates to but not limited to the technical field of wireless communication, especially a clock processing method, device and PTP equipment. Background technique [0002] The IEEE1588 standard, that is, the precision clock synchronization protocol standard for network measurement and control systems (IEEE1588 Precision Clock Synchronization Protocol), referred to as: PTP (Precision Timing Protocol), is currently the main technology for clock synchronization. [0003] Mobile backhaul networks are increasingly used in Long Term Evolution Advanced (abbreviated as: LTE-A) and Time Division Duplexing (abbreviated as: TDD) LTE systems. And phase synchronization put forward higher requirements. Although the Global Positioning System (Global Positioning System, referred to as: GPS) can be used as a reference for clock synchronization, it is difficult to be widely used in all base stations. Currently, operators use more 1588V2 (PTP) techn...
