Problems solved by technology

In this case, the multi-carrier joint system will not report alarms related to the cell or carrier frequency, and there is a maintenance blind spot, which will seriously affect the use and performance of the entire multi-carrier joint system, and even cause the entire multi-carrier joint system to system crash

Embodiment Construction

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. 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 with each other.

[0024] Although there is a self-loop at a certain output port of the BBU (if the BBU and RRU are connected by optical fiber, the self-loop can be called a fiber self-loop), there will be no alarm related to the logical cell or logical carrier frequency, but in the following In the embodiment, the link alarm of the RRU connected to the BBU port is used as the basis for judging whether a self-loop occurs, figure 2 is a flowchart of a self-loop processing method according to an embodiment of the present invention, such as figure 2 As shown, the process includes the following steps:

[0025] Step S202, the BBU detects the link alarm of the RRU, and determines that the port on the BBU corresponding to...

Abstract

The invention provides a self-loop processing method and a self-loop processing device. The method comprises the following steps that: a baseband processing unit detects a link alarm of a radio remote unit and determines that a port on the baseband processing unit corresponding to the radio remote unit corresponding to the link alarm is a self-loop port; and the baseband processing unit carries out port selection in other ports except for the self-loop port. By the self-loop processing method and the self-loop processing device which are provided by the invention, the robustness of a multi-carrier combination system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a self-loop processing method and device. Background technique [0002] figure 1 It is a schematic diagram of the connection between the BBU and the RRU of the distributed base station according to the prior art, such as figure 1 As shown, a distributed base station (Base Transceiver Station, BTS for short) includes a radio remote unit (Radio Remote Unit, RRU for short) and a base band processing unit (Base Band Unit, BBU for short). The link between the BTS and the Base Station Controller (BSC for short) realizes the transmission of signaling, voice or data services through cable output, satellite transmission or microwave, and the RRU and BBU can use fiber optic transmission. [0003] In the field of wireless communication, in order to prevent user equipment (User Equipment, referred to as UE for short) from inter-cell handover within continuous wireless signal coverage, mu...
