Title:
LTE FRAME OFFSET VALUE CALCULATION METHOD, APPARATUS AND SYSTEM, AND DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/197599
Kind Code:
A1
Abstract:
Disclosed in the present invention are an LTE frame offset value calculation method, apparatus and system, and a device and a storage medium. The method comprises: performing time synchronization on a sampling tool; sampling target base station data at a specified sampling rate by using the sampling tool that has successfully experienced time synchronization, wherein the target base station data comprises a sampling data buffer area and a sampling count; searching for a protocol signal on the basis of the sampling data buffer area and according to an LTE protocol, comparing the protocol signal with a synchronization signal, and outputting a determination result; if the determination result is that the protocol signal is synchronous with the synchronization signal, recording the current sampling count, and calculating a frame offset value of a target base station; and if the determination result is that the protocol signal is not synchronous with the synchronization signal, returning to the step of sampling target base station data at a specified sampling rate by using the sampling tool that has successfully experienced time synchronization, and executing subsequent steps. In the present invention, there is no need to use a dedicated decoding chip to execute complicated search and decoding operations, and a frame offset value of a target base station can be calculated only according to a sampling count and a specified sampling rate, such that the operation efficiency can be improved, and the decoding cost can be saved on.
