CHARGING INTERFACE FOR INTER-RADIO ACCESS TECHNOLOGY HANDOVER OF CALL SESSIONS

摘要

A charging session identifier is transmitted over an interface between a first base station and a second base station in response to initiation of a handover of a call session between the first and second base stations. The first and second base stations operate according to different radio access technologies. The first base station transmits first charging information collected by the first base station for the call session and second charging information collected by the second base station for the call session to a network charging system using the identifier.
