ABSTRACT:
A charging process method, relating to communication network, is disclosed according to embodiments of the present invention. The method includes receiving a charging request containing a type of a second method when the method for a user equipment to access a packet data network gateway has been changed from a first method to the second method; performing, based on the charging request, charging control over the used service units in a charging mode corresponding to the first method for the user equipment to access the packet data network gateway and reserving service units for the charging session for the second method based on a charging mode corresponding to the second method for the user equipment to access the packet data network gateway. A network system, a packet data network gateway and a charging system are provided according to embodiments of the present invention accordingly. Embodiments of the present invention can be applicable to a charging process in a situation when the method for a user equipment to access the packet data network gateway changes.
