Abstract:
1. A method of passive evaluation of push-to-talk traffic in a communication network, said passive evaluation implying non-intrusive monitoring of ongoing processes without interference or disturbance of network operation and push-to-talk traffic is generated through at least one push-to-talk session dividing into a plurality of data transactions according to different classes, a first traffic class covers interactions between a user terminal and the communication network for log-on of user terminals to the communication network, a second traffic class covers interactions between a user terminal and a push-to-talk management node in the communication network for push-to-talk session initialization, and a third traffic class covers exchange of push-to-talk payload data among user terminals, the method comprising the steps: capturing data transaction in the communication network by time-stamping data packets exchanged during data transactions and storing time stamped captured data packets in a trace memory; extracting interpretations of data transactions being relevant for push-to-talk, traffic classes, and users, from captured data transactions; storing a correlation of extracted interpretations of data transactions being relevant for push-to-talk, traffic classes, and users in a traffic data base; and calculation at least on performance indicator with respect to at least one selected push-to-talk session as a function of information stored in the traffic database.
