Problems solved by technology

[0005] During the process of creating the present invention, the inventors found that at least the following problems existed in the above-mentioned technologies: in the A-interface IP solution of the GSM network, if the link between BSC 11 and MGW 12 is disconnected, although BSC 11 or MWG 12 can pass through The link detection technology detects that the link has been disconnected, but because there is no signaling to report link abnormality information to MSC 13, MSC 13 still assigns the IP address and port of MGW 12 to BSC 11, resulting in BSC 11 and MSC 13 The signaling plane between BSC 11 and MGW 12 is disconnected but the user plane is unreachable

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0020] when referring to figure 1 In the GSM network shown, a method for reporting link abnormality information in the embodiment of the present invention is as follows figure 2 shown, including the following steps:

[0021] Step s201, check whether the link between the BSC 11 and the MGW 12 is normal; if yes, it can end, otherwise, it can go to step s202. In this embodiment, BFD (Bidirectional Forwarding Detection, bidirectional forwarding detection protocol) is used to detect the link between the BSC 11 and the MGW 12 . The detection method is as follows: BFD can regularly and quickly send BFD control packets between BSC 11 and MGW 12, and detect at the receiving end, if no BFD packet is received beyond three agreed periods, it is determined that the link between BSC 11 and MGW 12 is abnormal , the abnormal situation inc...

Abstract

The invention discloses a method for reporting the abnormal information of a link. The method comprises the following steps: detecting whether a link between a base station controller and a media gateway is normal; and sending a message carrying with the abnormal information of the link to a mobile switching center when abnormal situations happen to the link. The invention further discloses a base station controller, a media gateway and a global mobile communication system network. In a GSM network, when abnormal situations occur to a link between BSC and MGW, a message containing the abnormal information of the link is sent to MSC through the BSC or the MGW, so that the MSC stops to assign the flow, thereby preventing the problems that a signaling plane is smooth and a user plane is not smooth.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for reporting link abnormality information. Background technique [0002] With the rapid development of wireless communication technologies, GSM (Global System Mobile, Global System for Mobile Communications) networks are widely used. A GSM network structure such as figure 1 As shown, it includes BSC 11 (Base Station Controller, base station controller), MGW 12 (Media GateWay, media gateway) and MSC 13 (Mobile Switching Center, mobile switching center). The BSC 11 communicates with the MGW 12 and the MSC 13 respectively through the A interface, and the MGW 12 is connected to the MSC 13 . The connection between the MSC 13 and the BSC 11 may generally be referred to as a signaling plane connection, and the connection between the MGW 12 and the BSC 11 may generally be referred to as a user plane connection. [0003] At present, i...
