Abstract
A cellular traffic monitoring system includes: a traffic detection function (TDF) module to monitor cellular traffic associated with a cellular subscriber device, and to generate detection output which includes at least one of: a type of an application associated with the cellular traffic of the cellular subscriber device, and a type of the cellular traffic of the cellular subscriber device. The cellular traffic monitoring system further includes a policy charging and enforcement function (PCEF) module to enforce one or more charging rules to the cellular subscriber device, based on the detection output.

A cellular traffic monitoring system comprising:
- a policy and charging rules function (PCRF) module server configured to create a set of application detection and control (ADC) rules;
- a Service Data Flow (SDF) based policy charging and enforcement function (PCEF) module server configured to enforce one or more charging rules to a cellular subscriber device, based on SDF data;
- wherein the SDF-based PCEF module server is associated with an online charging system (OCS) that is able to perform SDF-based online charging based on data received from said SDF-based PCEF module server;
- wherein the SDF-based PCEF module server is associated with an offline charging system (OFCS) that is able to perform SDF-based offline charging based on data received from said SDF-based PCEF module server;
- a traffic detection function (TDF) module server, implemented as a separate module server from said SDF-based PCEF module server;
- wherein the TDF module server is connected directly to said OCS;
- wherein the TDF module server is connected directly to said OFCS;
- wherein the TDF module server is configured (a) to monitor cellular traffic associated with said cellular subscriber device, (b) to perform payload data inspection by using a Deep Packet Inspection (DPI) technique, (c) to apply said Application Detection and Control (ADC) rules in order to detect an application running on said cellular subscriber device, (d) to generate detection output which includes at least one of:
- a type of an application associated with said cellular traffic of said cellular subscriber device, and
- a type of said cellular traffic of said cellular subscriber device;
- and (e) to generate application-based detection output that enables at least one of the OCS and the OFCS to apply, on per-application basis, different charging rates to different applications being used over a cellular network in which said cellular subscriber device operates;
- wherein a same cellular communication session is subject to both (i) SDF-based charging based on output from the PCEF module server, and (ii) application-based charging based on output from the TDF module server;
- wherein at least one of said OCS and OFCS, is to perform application-based differential charging towards said cellular subscriber device based on application-based detection output that was generated by the TDF module server by using said DPI technique and by applying said ADC rules,
- wherein at least one of:
- said PCRF module, said SDF-based PCEF module, and said TDF module, is implemented by utilizing at least a hardware component.
