Device and method for end-to-end media plane detection across network elements

Abstract

The invention discloses a cross-network element end-to-end media plane detection device, which comprises a front-end media plane detection module, a rear-end media plane detection module and a call processing module, wherein the front-end media plane detection module is used for storing one or more sections of standard test tones, and when receiving a media stream test starting message, transmitting the stored standard test tones to the rear-end media plane detection module; the rear-end media plane detection module is used for receiving the standard test tones from the front-end media plane detection module, comparing the received standard test tones with own stored standard test tones and judging a media plane problem; and the call processing module is used for issuing an analogue call flow, and transmitting a media stream test starting command to the front-end media plane detection module. The invention also discloses a cross-network element end-to-end media plane detection method. By the device and the method, the media plane problem in a system can be timely discovered, the media plane problem detection efficiency can be improved, a failure detection cycle can be shortened and the normal running of the communication system can be ensured.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a device and method for end-to-end media plane detection across network elements. Background technique [0002] Packet-based CDMA2000BSS (BaseStationSubsystem) can use TDM (TimeDivisionMultiplexing, time division multiplexing) transmission mode to access the CDMA2000 core network based on softswitch, or use IP (Internet protocol) switching technology to access to Realize the CDMA2000 core network based on softswitch. Whether the core network is accessed by TDM or IP, the transmission process of the entire media stream is very complicated. From MS (MobileStation, mobile station) to BTS (BaseTransceiverSystem, base station transceiver), a When the reverse service frame starts, it needs to go through the CHM (Channel Module) on the BTS side, the interface board, the interface board on the BSC side, the primary switch, the secondary switch, the SDU (selector unit), the IP ...

AI Technical Summary

Problems solved by technology

In this complex transmission process, the entire BSC side needs to allocate a lot of resources for calls, such as CE (ChannelElement, channel unit), SE (SelectorElement, selector unit), VE (VocoderElement, vocoder unit), CIC (CircuitIdentificationCodes, circuit identification code) resources, etc., any problem with any resource may cause media failure or other media problems, and any problem in the transmission process will also cause the same problem

As the CDMA2000 network is used more and more on a large scale, more and more network instability, poor voice quality of users, and a large number of complaints will inevitably be encountered, among which the problems of the media are often the most difficult to troubleshoot. , Media problems include single board failure, packet loss, route loss, resource unavailability, etc. For these problems, a lot of manpower and material resources are needed, and maintenance personnel are often exhausted and put out fires everywhere, but with little effect
