METHOD AND SYSTEM FOR CONTROLLING QUALITY OF SERVICE OVER A TELECOMMUNICATION NETWORK

A method, a system and equipment for determining quality of telecommunication service over a telecommunication network, which provide: (a) obtaining data on quality of service over a number of routes in the network by determining, for each route, N parameters pi, each reflecting either a quality of transmission of a particular service through said route or a statistical characteristics of said route's availability to a subscriber, and (b) building an objective quality score (OQS) for each of the routes, the OQS being a multi-profile quality estimation equation presenting a sum of N said parameters pi taken with respective weight functions Wi(pi) thereof. Based on the score, one or more routes can be selected in the network (for example, for routing), which have the OQS value not lower than a predetermined OQS.
