Medium flow service quality reporting method

Abstract

The invention discloses a kind of the report method of the media service quality related to the communication field, enabling it to modify the real time of calling control stratagem and surmounting the negative elements that cause tremendous effect on the media service quality borne by IP network. It can not only make macroscopic assessment for the network service quality but also dynamically adjust the calling control stratagem for a simple and highly efficient solution for the MGC real time to know the status between MG and the media effluent service quality. On the one hand the reporting method of this kind of media flow service quality redefines the cycle of reporting package of service quality, which put together the relevant matters with the heightening of regulating real time in the calling control stratagem with the service quality report and the corresponding observation and on the other hand, in that mechanism, MG, following the activation of the media effluence, takes samples of cycle period in order to obtain and add up the information of the media effluent service quality according to the RTCP information; after receiving the qospr / qost, it is periodically added up and reported.

Description

technical field [0001] The invention relates to the field of communications, in particular to media stream service quality monitoring technology. Background technique [0002] With the development of telecommunication technology, the Next Generation Network ("NGN" for short) has shown unlimited development potential. Based on the starting point of protecting the original telecommunication network investment, NGN must support the smooth transition of the existing telecommunication service network, so NGN must maintain compatibility with the original telecommunication network for a long time, so different networks must There must be a gateway device that can provide different services, different interfaces, and different function conversions. [0003] Moreover, with the development of technology and the deepening of problem understanding, the idea of ​​separation of gateway functions is proposed, that is, the gateway functions are decomposed into two parts: high-level call co...

AI Technical Summary

Problems solved by technology

[0014] In practical applications, the above-mentioned solution has the following problems: it reports the statistical parameters of the media stream quality of service of the call only when a call ends, and does not fully consider the real-time nature of call control policy adjustments. Poor real-time adjustment

For example, voice signals are carried by IP technology in NGN. Since voice signals are highly sensitive to delay, the network delay is required to be low during each call. However, the network may be congested during a certain call. In the existing technical solution, only after the user hangs up and ends the call, the MG reports the statistical parameters of the service quality of the media stream of the call, so that the MGC understands that the service quality of the media stream of the call is poor, and adjusts the subsequent call control strategy. For example, in the case of network congestion, control the number of successful call connections or use a voice codec algorithm with low bandwidth requirements, etc.

However, the loss caused by the last call process of the user cannot be compensated

The existing technical solutions are relatively more suitable for evaluating the macro service quality of the network within a certain period of time, and the ability to adjust the micro service quality of each call is relatively poor
