Distributed link system of base station and link protecting method thereof

Abstract

The embodiment of the invention provides a distributed link system of a base station, comprising a wireless network controller and a plurality of distributed base station devices controlled by the wireless network controller, wherein each distributed base station device comprises a base band unit connected to the wireless network controller and a plurality of serially-connected radio frequency far-end units connected to the base band units; and in the first distributed base station device and the second distributed base station device which are adjacent to each other, a last-stage radio frequency far-end unit in the serially-connected radio frequency far-end units connected to the distributed base station device is connected with the second distributed base station device by a standby link. According to the distributed link system of the base station, provided by the embodiment of the invention, the last-stage radio frequency far-end unit in the distributed base station device is linked to the adjacent distributed base station device by using the standby link, so that the utilization rate of the equipment of a mobile communication system is effectively improved while the link system is protected.

Description

technical field [0001] The invention relates to the technical field of wireless communication network planning, in particular to a distributed base station link system and a link protection method thereof. Background technique [0002] With the development of mobile communication technology, the construction of the third-generation communication system has made great progress. As an important branch of the third-generation mobile communication system, the construction of the mobile communication system has also achieved many beneficial results. The distributed base station equipment (NodeB) is composed of a base band unit (BBU, Base Band Unit) and a radio frequency remote unit (RRU, Remote RF Unit). Such as figure 1 shown. The RRU is connected to the BBU through an Ir interface (Interface between the RRU and the BBU), and the BBU is connected to a radio network controller (RNC, Radio Network Controller) through an Iub interface (Interface between the BBU and the RNC). The...
