Abstract

The invention is applicable to the field of communication, and provides an LTE micro base station, and a frame header deviation detection method and a synchronization method thereof. The frame headerdeviation detection method of the LTE micro base station comprises the steps of acquiring a first timestamp input to an external synchronous clock source of the LTE micro base station, and a second timestamp of a frame header of a local cell in last time; computing a difference between the second timestamp and the first timestamp to acquire a first time difference; and determining frame header deviation of a remote cell according to the first time difference. According to the base station and the methods provided by the invention, the frame header deviation of the remote cell can be automatically detected, the LTE micro base station can be quickly and accurately synchronized, deployment speed and efficiency of the LTE micro base station are improved, participation of manual configuration is reduced, system configuration accuracy is improved, and work efficiency is effectively improved.

Description

technical field [0001] The invention belongs to the communication field, and in particular relates to an LTE micro base station and a method for detecting frame header offset and a synchronization method thereof. Background technique [0002] With the development of science and technology and the advancement of mobile communication technology, mobile phones, as the most commonly used mobile terminals, have more and more demands based on the Internet, and put forward higher and higher requirements for the capabilities of mobile networks. At present, the 4G macro base stations of the three major domestic operators have been deployed and popularized on a large scale. Among them, the TD-LTE system, as a time division system, has very high requirements for synchronization. As a useful supplement to macro base stations, LTE micro base stations can be deployed in local blind spots and places with heavy traffic, effectively improving the user experience of 4G data service users.
