Embodiment Construction

[0042] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0043] figure 1 It is a schematic diagram of a BTS in an embodiment of the present invention. As shown in the figure, the BTS in this embodiment includes a BBU and one or more RRUs, wherein,

[0044] The RRU will detect whether their respective radio frequency remote units are faulty in real time or regularly, and report an alarm to the BBU if a fault is detected;

[0045] After the BBU receives the alarm of the radio frequency failure, it judges according to the alarm whether the radio frequency failure affects the operation state of the corresponding carrier frequency, and...

Abstract

The present invention provides a method for dealing with radio frequency faults and BBU and BTS. The method includes: receiving a radio frequency fault alarm; judging whether the radio frequency fault affects the operating state of the corresponding carrier frequency according to the alarm, and if so, blocking the The above carrier frequency, and dynamically switch the faulty radio frequency. The invention can realize the automatic switching recovery when the radio frequency TRX of the carrier frequency fails.

Description

technical field [0001] The invention relates to the field of GSM mobile communication network, in particular to a method for dealing with radio frequency faults, BBU and BTS. Background technique [0002] GSM (Global System for Mobile Communications) divides the service area into multiple cells, and each cell is provided with wireless coverage by a corresponding Base Transceiver Station (BTS). In GSM, a BTS consists of one or more radio transceivers (TRX), each TRX handles signal processing, radio reception and radio transmission over eight physical time slots. In principle, TRX can be divided into a radio frequency processing unit and a baseband processing unit. In the field of new generation communication equipment manufacturing, remote radio frequency processing units are gradually attracting attention. The typical architecture is to divide the BTS into two parts: BBU (Base Band Unit, baseband unit) + RRU (RemoteRadio Unit, radio frequency remote unit). The two are conn...
