TS 23.125 (SA2)
Overall High Level Functionality and Architecture Impacts of Flow based Charging – Stage 2

|   ToC   |   3GPP‑Page   |   ETSI‑search   |   Help   |

(P) V6.8.0    2006/03    50 p.

Rapporteur:  Mr. Boman, Krister
Descendant:  TS 23.203    

This TS specifies the overall high level functionality and architecture impacts of Flow Based Charging (FBC).

Note:  The functionality of 23.125 (Flow based Charging) has been combined with Policy Control functionality from Rel-7 onwards into a single new TS: TS 23.203 (Policy and Charging Control - PCC).
