Abstract:
1. A method for collecting of statistical data of IMS or Session Initiation Protocol (SIP) based services in a mobile Internet Protocol (IP) based multimedia subsystem, IMS, whereby an evaluation of the service dependent user behavior of communication participants during a connection setup initiated by a mobile communication terminal device of a subscriber is carried out with an application, comprising: providing an Online Statistics and Advertisement Server, OSAS, integrated as a new application server component into IMS session applications and the corresponding signaling traffic; wherein the OSAS has access to all of the relevant SIP signaling and to the signaling data during the session setup and can determine from it online all relevant parameters; the OSAS collecting during connection setup run-time online statistical data for IP based services and, during the establishment of said connection, transmitting information to the mobile communication terminal device of the subscriber as a function of the collected online statistical data; said method including the following steps: loading a subscriber profile into a Call Session Control Function (CSCF) containing an OSAS trigger that invokes OSAS functions; the mobile communication terminal device sending an SIP INVITE message to the CSCF to initiate an SIP INVITE session; the CSCF forwarding the SIP INVITE message to the OSAS, and the OSAS trigger invoking at least one OSAS function; the OSAS removing from the forwarded SIP INVITE message online statistical data and adding media to the SIP INVITE message and then sending the SIP INVITE message containing the added media back to the CSCF; and the CSCF sending to the mobile communication terminal device a provisional response containing the OSAS added media.
