Abstract
A method of monitoring broadcast or multicast streaming service in a communications network comprising collecting (102) quality feedbacks related to the streaming service, determining (106) a maximum distance to a neighbour in a cluster and a minimum number of values required to form a cluster (106). The method further comprises grouping (108) collected values from the feedbacks into clusters based on the maximum distance to a neighbour in a cluster and the minimum number of values required to form a cluster and then mapping (112) the clusters onto topology of the network and determining (114) location of a problem causing degradation of the service.

24. A method, for use in a network element, of monitoring broadcast or multicast streaming service in a communications network comprising:
-
collecting values of a parameter indicative of quality of the streaming service; determining a maximum distance between two neighbour values in a cluster, wherein the determination is based on the collected values indicative of quality of the streaming service above a predefined level; determining a minimum number of values required to form a cluster, wherein the determination is based on the collected values indicative of quality of the streaming service above the predefined level; grouping the collected values that are below the predefined level into clusters based on the determined maximum distance between two neighbour values in a cluster and the minimum number of values required to form a cluster; mapping the clusters onto topology of the network; determining location of a problem causing degradation of the service based on the mapping. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A network element for use in a communications network providing broadcast or multicast streaming service comprising a feedback analyser module and an interface to communicate with the communications network, wherein the feedback analyser module is adapted to:
-
collect values of a parameter indicative of quality of the streaming service; determine a maximum distance between two neighbour values in a cluster, wherein the determination is based on the collected values that indicate quality of the streaming service above a predefined level; determine a minimum number of values required to form a cluster, wherein the determination is based on the collected values that indicate quality of the streaming service above the predefined level; group the collected values that are below the predefined level into clusters based on the determined maximum distance between two neighbour values in a cluster and the minimum number of values required to form a cluster; map the clusters onto topology of the network; determine location of a problem causing degradation of the service based on the mapping. - View Dependent Claims (35, 36)

37. A communications network comprising a streaming server providing broadcast or multicast streaming service to user equipment, network nodes and a network element, wherein said network element comprises a feedback analyser module and an interface to communicate with the communications network, wherein the feedback analyser module is adapted to:
-
collect values of a parameter indicative of quality of the streaming service; determine a maximum distance between two neighbour values in a cluster, wherein the determination is based on the collected values that indicate quality of the streaming service above a predefined level; determine a minimum number of values required to form a cluster, wherein the determination is based on the collected values that indicate quality of the streaming service above the predefined level; group the collected values that are below the predefined level into clusters based on the determined maximum distance between two neighbour values in a cluster and the minimum number of values required to form a cluster; map the clusters onto topology of the network; determine location of a problem causing degradation of the service based on the mapping. - View Dependent Claims (38, 39)
