Embodiment Construction

[0021] The embodiments of the present invention design a method and device for information synchronization. The method uses regular frame stealing technology to establish a dedicated channel, so that the base station can still obtain synchronization information when there is no channel dedicated to synchronization in the wireless channel. Information synchronization.

[0022] The preferred embodiments of the present invention will be described below in conjunction with the drawings.

[0023] Refer to figure 1 As shown, an information synchronization method designed in an embodiment of the present invention includes the following steps:

[0024] Step 101: The base station confirms the level N of the acquired synchronization information.

[0025] Whenever the base station acquires a piece of synchronization information, it confirms the level N of the acquired synchronization information, and the confirmation process has the following two situations:

[0026] 1) The base station uses the ...

Abstract

An embodiment of the invention discloses a method and a device for information synchronization. The method includes the steps: confirming the level N of acquired synchronization information; performing information synchronization for a base station according to the confirmed N synchronization information, and generating the N+1 synchronization information according to synchronization results; and transmitting the N+1 synchronization information on a corresponding wireless channel according to a mapping relation between preset synchronization information and the wireless channel. The N is a positive integer, and the method is used for solving the problems that when a channel specially used for synchronization is absent in a wireless transmission protocol, the information synchronization cannot be realized by the aid of the wireless channel, and same frequency interference is caused by asynchronous information transmitted by a plurality of base stations in the prior art.

Description

Technical field [0001] The present invention relates to the field of mobile communication technology, in particular to a method and device for information synchronization. Background technique [0002] In a wireless communication network, if information can be synchronized between various base stations, it can bring benefits such as clock synchronization. However, for indoor small cell base stations, the signals in the coverage area are vulnerable to penetration loss and other factors. The impact is weakened. Therefore, it is impossible to ensure that all indoor small cell base stations can obtain signals from outdoors and synchronize information. The signal from outdoors may be a GPS (Global Positioning System, global positioning system) signal, a macro cell base station signal, etc. In some scenarios that require deep coverage, GPS signals and macro cell base station signals are basically unable to penetrate obstacles. [0003] Information synchronization can also be carried ou...
