Abstract:
1. A method for performance management in a cellular mobile packet data network having a plurality of mobile stations linked to a plurality of base stations through a plurality of radio channels, the base stations being linked to a radio access network, and the radio access network being linked to a support node in a packet core network comprising the steps of: capturing raw traffic traces over standardized interfaces of the operational cellular mobile data network; building a traffic and session database by parsing through the traces in order to extract and correlate information about a plurality of user transactions which happened during a measurement period, wherein each user transaction is associated with a specific subscriber using captured session management signaling, and each user transaction is associated with a cell location using captured mobility management signaling, said building the traffic and session database comprises the steps of: storing summary data about the users transactions belonging to same user sessions together with a list of cells visited during the user sessions and the timestamps when the subscribers visited the cells; defining a set of key performance indicators; and calculating the set of key performance indicators using a subset of the information in the traffic and session database to monitor user perceived end-to-end performance on a cell level.
