Embodiment Construction

[0033] In the field of telecommunications, it is of great significance to enhance the maintainability of the time source. Operators often have some maintenance requirements during use, such as only processing packets from trusted time sources, temporarily prohibiting PTP ports from participating in selection, and forcing the selection of specific time sources. Therefore, it is necessary to enhance the maintainability of the time source.

[0034] This article describes a method and device for enhancing the maintainability of the time source, which implements maintenance functions including filtering packets from illegal sources, temporarily prohibiting PTP ports, and forcing the selection of time sources. The purpose of the present invention is to enhance the maintainability of the time source by filtering the time source data packets from illegal sources, increasing the manual intervention of maintenance personnel (such as forcing a specific time source to be selected, tempora...

Abstract

The present invention discloses a method for enhancing time source maintainability. The method includes: receiving time source packets and filtering the time source packets according to a preset filtering rule; preprocessing the residual time source packets after filtering; and selecting a time source according to the preprocessing result. The present invention also discloses an apparatus for enhancing time source maintainability. The apparatus includes a time source filtering unit, a time source preprocessing unit and a time source selection unit. With the method and apparatus of the present invention, the time source maintainability is enhanced effectively.

Description

technical field [0001] The present invention relates to the field of PTP (IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems), in particular to a method and device for enhancing maintainability of a time source. Background technique [0002] In wireless applications, base stations of some standards, such as UMTS TDD base stations, 3GPP2CDMA2000 base stations, and TD-SCDMA base stations, have requirements for the phase of adjacent base stations. For example, the phase difference between adjacent TD-SCDMA base stations cannot exceed 3us. To meet, can also be met through the PTP protocol. With the construction of 3G network, the PTP protocol transfer time using packet switching technology will be more widely used. [0003] Maintainability is a very important factor when applied in the telecommunications field. On the premise of ensuring the performance of the base station, the current PTP protocol based on packet switchi...
