Embodiment Construction

[0060] In this embodiment, when performing clock control input by multiple reference sources, first obtain the current clock control parameters of the local clock, then calculate the clock control parameters according to the current clock control parameters and the selected reference source, and then calculate the clock control parameters according to The calculated clock control parameters are used to adjust the local clock step by step, so that the local clock is synchronized with the selected reference source. A valid reference source is selected, thereby completing the switching process between reference sources.

[0061] In this embodiment, in order to effectively manage multiple reference sources better, a reference source policy may be preset. Of course, the reference source strategy can also be set or adjusted during actual application. The reference source strategy can be divided into a public strategy and a dedicated strategy, where the public strategy is mainly for...

Abstract

A clock control method, device and base station for input having multiple reference sources are provided by the invention, which relates to the mobile communication field. In the method, device, and base station, a first reference source for local clock synchronization is selected from a plurality of reference sources; and the current clock control parameter of said local clock is obtained; according to the current clock control parameter, a first clock control parameter is calculated using the first reference source; said first clock control parameter is used for local clock synchronization adjustment; the local clock is adjusted step-by-step according to the first clock control parameter, so as to synchronize the local clock with the first reference source. The method, device and base station of the invention ensure that when handover occurs among a plurality of reference sources, the local clock can transition smoothly from the original reference source clock synchronization to the new reference source synchronization.

Description

technical field [0001] The invention belongs to the field of mobile communication, and in particular relates to a multi-reference source input clock control method, device and base station. Background technique [0002] If the base station can work normally, it must be synchronized with the clock of the transmission equipment or the clock of the superior base station. For the base station, in order to complete the clock synchronization with the transmission equipment, it must receive the reference source input by the transmission equipment to the base station, and use the input reference source to synchronize with the local clock, in order to complete the subsequent work and tasks of the base station. [0003] However, due to different countries, different regions, different environments and different operators using different transmission equipment, the reference source that the transmission equipment can provide to the base station has various forms, such as GPS (Global Po...
