Abstract
A comprehensive approach for segmenting encrypted streams of media content into individual sessions is provided herein. Particularly, a network node identifies a connection to a known content delivery related domain and receives the data packets comprising the encrypted streams over the connection. The data packets comprise a pattern of one or more features indicating a media content start event for the media content being provided to a subscriber via the connection. The subsequent network activity is then monitored in a pre-determined time frame and an associated pattern analyzed. A media content start event may then be detected based on the analysis of the pattern.

1-41. (canceled)
A method for detecting media content start events, the method comprising:
- receiving data packets from a monitoring device, wherein the data packets comprise a pattern of one or more features indicating a media content start event for media content being provided to a subscriber;
- and
- detecting the media content start event based on an analysis of the pattern of one or more features.
A network node for detecting media content start events, the network node comprising:
- communications interface circuitry configured to communicate with at least one monitoring device configured to monitor media session traffic in a communications network;
- and
- processing circuitry operatively coupled to the communications interface circuitry and configured to:
- receive data packets from the monitoring device, wherein the data packets comprise a pattern of one or more features indicating a media content start event for media content being provided to a subscriber;
- and
- detect the media content start event based on an analysis of the pattern of one or more features.
A non-transitory computer-readable medium storing computer program code thereon that, when executed by processing circuitry of a network node configured to detect media content start events, causes the network node to:
- receive data packets from the monitoring device, wherein the data packets comprise a pattern of one or more features indicating a media content start event for media content being provided to a subscriber;
- and
- detect the media content start event based on an analysis of the pattern of one or more features.
