Embodiment 1

[0059] Figure 6 It is a schematic flow chart of Embodiment 1 of the protection method of the IQ switching link of the large-capacity baseband pool realized by the present invention, and it is a specific implementation method of the protection switching of part of the IQ switching link, such as Figure 6 As shown, the method includes the following steps:

[0060] Step 601, the IQ link management module of the switching equipment detects that the IQ switching link (link 3) between the BBU11 and the switching equipment fails, the IQ link management module of the switching equipment retrieves the previous allocation information, and finds the The carrier is carried on the IQ switching link, but it is found that the source frame of CELL1 is not this frame, but on BBU11, so it is necessary to notify the IQ link management module of BBU11 of the IQ switching link of CELL1 through the IQ switching link failure notification message Road (link 3) breaks down; In the present invention,...

Embodiment 2

[0068] Figure 7 It is a schematic flow chart of Embodiment 2 of the protection method of the IQ exchange link of the large-capacity baseband pool in the present invention, and it is a specific implementation method of the protection switching of all IQ exchange links, such as Figure 7 As shown, the method includes the following steps:

[0069] Step 701, the IQ link management module of the switching device detects that the IQ switching link (link 3) between the BBU11 and the switching device fails, and the IQ link management module of the switching device retrieves the previous distribution information and finds that the cell CELL1 The carrier is carried on the IQ switching link, but it is found that the source frame of CELL1 is not this frame, but on BBU11, so it is necessary to notify the IQ link management module of BBU11 of the IQ switching link of CELL1 through the IQ switching link failure notification message The link (link 3) fails.

Abstract

The invention discloses a protection method and system of IQ exchange link of high-capacity base band pool. The method comprises that when the IQ exchange link breaks down, an IQ link management module informs a resource management module of the broken down IQ exchange link, the resource management module deletes the broken down IQ exchange link, does not dismantle base band resources and radio frequency resources associated with carriers carried on the broken down IQ exchange link, and reapplies an IQ exchange link from the IQ link management module. The IQ link management module looks up available IQ exchange links, and sends the information of the found available IQ exchange link to the resource management module. The resource management module carries out configuration according to the received information of the IQ exchange link, and completes the protective switching of the IQ exchange links. According to the technical scheme of the protection method and the system of the IQ exchange link of the high-capacity base band pool, the protective switching of the IQ exchange links can be achieved under the condition of not influencing business.

Description

technical field [0001] The invention relates to the field of wireless networks, in particular to a method and system for protecting an IQ exchange link of a large-capacity baseband pool. Background technique [0002] In the current wireless network, the base station mostly adopts the architecture of baseband processing unit (BBU, BuildingBasebandUnit) + radio frequency remote unit (RRU, RadioRemoteUnit), and the two are connected by optical fiber. BBU and RRU can be one-to-one or one-to-many The way. [0003] At present, the base station has implemented a single baseband pool, that is, a baseband pool within one BBU. In the BBU+RRU architecture, physical resources can be divided into three components: baseband resources, radio frequency resources, and IQ switching links. Among them, the IQ switching links are data bearing channels between baseband resources and radio frequency resources. When the base station configures a cell, it does not need to bind baseband resources, ...
