Claim 0:
1. A method implemented in a network device for estimating network performance of a path between a terminal device and an application server through a core network, the method comprising:
measuring network performance of a portion of the path within the core network to obtain one or more partial network performance measurements of the portion of the path in a first period;
obtaining one or more end-to-end measurements of the path in the first period, wherein the end-to-end measurements are values of an end-to-end performance indicator measured outside of the core network;
providing the partial network performance measurements of the portion of the path in the first period and the one or more end-to-end measurements of the path in the first period to a machine learning function to determine a set of coefficients of the machine learning function; and
estimating one or more values of the end-to-end performance indicator in a second period after the first period, by applying partial network performance measurements of the portion of the path in the second period to the machine learning function, the one or more values of the end-to-end performance indicator in the second period indicating the network performance of the path between the terminal device and application server through the core network.
