Embodiment 1

[0067] Embodiment 1 of the present application provides a method for detecting RRU link abnormality, such as figure 2 As shown, the method includes the following steps:

[0068] S201: Obtain M pieces of first parameter information of the RRU, where each of the first parameter information includes at least gateway information or IP information, and M is an integer greater than or equal to 1;

[0069] In the specific implementation process, the acquisition of M first parameter information, such as image 3 As shown, the following processes can be included:

[0070] S301: Send a broadcast message every preset time interval;

[0071] S302: Obtain M pieces of first parameter information sent to a BBU based on the broadcast information.

[0072] After the RRU is running, it does not know its own IP address, nor does it know the information of the BBU connected to it. For example: suppose the IP information of an RRU is: 200.254.0.8, and the IP of its original BBU is: 200.254.3.1...

Embodiment 2

[0113]In this embodiment, it is mainly introduced that in UMTS (Universal Mobile Telecommunications System: universal mobile communication system) products, when the BBU connected to the RRU changes, because the topology information does not change, the RRUID does not change. How to detect whether there is a problem with the RRU link.

[0114] Assumption: connect the RRU to the interface board of a BBU, first delete the configuration information of the RRU, then physically connect the RRU to another interface board of the same BBU, and then configure the RRU with the same configuration information .

[0115] like Figure 5 As shown, the link of the RRU can be detected in the following manner:

[0116] S501: RRU saves its own gateway information, IP information and RRUID in advance, for example:

[0117] The gateway information is: 200.254.3.16

[0118] The IP information is: 200.254.0.8

[0119] The RRUID is: 11

[0120] S502: After the RRU works normally, send broadcast...

Embodiment 3

[0128] In this embodiment, the following two situations are assumed:

[0129] ① Connect the RRU to an interface board with a fixed slot and configure it. After the RRU starts normally, remove the interface board together with the optical fiber and insert it into another slot.

[0130] ② Connect an RRU that has been started normally from one BBU to another BBU directly.

[0131] In this case, the following methods can be used to detect the RRU link:

[0132] The RRU regularly sends a broadcast message to the baseband board on the BBU side, specifically an address request message, mainly requesting to obtain gateway information;

[0133] After receiving the broadcast message, the BBU side interface board replies with a broadcast response message;

[0134] After the RRU receives the response message, it will parse the response message and compare the gateway information in it with the pre-stored gateway information. If the compared fields are inconsistent, it can be considered...

Abstract

The present invention discloses a method for detecting an abnormal link of a remote radio unit and a remote radio unit. The method for detecting an abnormality of a remote radio unit includes: acquiring M pieces of first parameter information of a remote radio unit, wherein each The first parameter information includes at least gateway information or IP information, and M is an integer greater than or equal to 1; each of the M first parameter information is combined with the original parameter information of the remote radio unit Perform matching to obtain a matching result; judge whether the matching result satisfies a preset condition; when the matching result does not meet the preset condition, determine that the remote radio unit link is abnormal.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method for detecting link abnormality of a remote radio unit and a remote radio unit. Background technique [0002] With the continuous development of communication technology, more and more base station products have been produced. Among them, the distributed base station is the most widely used. Because the distributed base station has the advantages of low cost and strong environmental adaptability, it basically represents the trend of the "next generation base station". [0003] The distributed base station divides the base station into RRU (Radio Remote Unit: RRU) and BBU (Building Baseband Unite: BBU). The two are connected by optical fiber through an open standard interface, and the network can be flexibly built. The RRU can be installed close to the antenna and connected to the BBU through an optical fiber, so that the baseband signal can be transmi...
