Cross-network element end-to-end media plane detection device and method

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 communication field, in particular to a device and method for end-to-end media plane detection across network elements. Background technique [0002] The packet-based CDMA2000BSS (Base Station Subsystem) can be connected to the softswitch-based CDMA2000 core network through TDM (Time Division Multiplexing) transmission mode, or IP (Internet protocol). The switching technology is connected to the CDMA2000 core network based on soft switching. Regardless of whether TDM is used to access the core network or IP is used to access the core network, the entire media stream transmission process is very complicated, from MS (Mobile Station, mobile station) to BTS (Base Transceiver System, base transceiver station) ) to start sending a reverse service frame, it needs to go through the CHM (Channel Module, channel processing module) on the BTS side, the interface board, the interface board on the BSC side, the primary switch,...

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 (Channel Element, channel unit), SE (Selector Element, selector unit), VE (Vocoder Element, vocoder unit ), CIC (Circuit Identification Codes, circuit identification code) resources, etc. Any problem with any of these resources may lead to 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
