An objective of this invention is to provide a method and apparatus for performing online charging to GCS over LTE EPS/MBMS. Specifically, if a UE initiates a session to a GCS-AS, the GCS-AS sending an online charging initial request to a corresponding OCS, based on a GCS-AS Ro interface; the OCS performing online charging to usage of said GCS-AS service data in response to said online charging initial request; the OCS sending a granted service unit and valid time information about the UE to the GCS-AS in response to the online charging initial request, based on said GCS-AS Ro interface; the GCS-AS sending the GCS-AS service data corresponding to said granted service unit, said valid time information, and a corresponding key to the UE, so as to make the UE decode said GCS-AS service data based on said key within said valid time information; if said GCS-AS service data is based on the EPS bearer, the OCS performing online charging to usage of said GCS-AS service data based on a special rating group; if said GCS-AS service data is based on the MBMS bearer, the OCS charging a content provider for providing said GCS service data. Compared with the prior art, the invention realizes the per-user MBMS online charging, and implements an effective and fair charging to all users who use GCS-AS service over LTE EPS/MBMS. |
