适用范围

It is recognized that IP-based networks are increasingly used to deliver voice services to customers. These networks can impact the end-to-end service quality perceived by users. In order to maintain network performance required to deliver the desired service quality, several operational issues have to be considered. These issues include defining network performance measuresand their objectives, interworking issues between networks employing a variety of technologies, network measurement points, information to be exchanged between network operators, etc.
