Abstract:
A method for charging an inter-Public Land Mobile Network (PLMN) roaming data service online, and a device are presented. The method includes, after determining that an access subscriber is a roaming subscriber, establishing, by a visited-place packet data network gateway, an online charging session for the access subscriber; determining a first charging information parameter list; sending, to a home online charging system, a first quota request message carrying a rating group; receiving a roaming data service quota of the rating group sent by the home online charging system; and sending first charging information to the home online charging system according to the first charging information parameter list. The disclosed embodiments can simplify a network connection between a visited-place Packet Data Network Gateways (PGW) and an Online Charging System (OCS) of another operator that has a roaming agreement with the visited-place operator, reduce network connection complexity, and improve network connection efficiency.

Claim (Index 6):
A packet data network gateway, comprising:\n a processor; and a computer-readable storage medium coupled to the processor and configured to store programming instructions for execution by the processor, the programming instructions instructing the processor to:\n send, to a home online charging function of a roaming subscriber that corresponds to an address of the home online charging function, a first request message used to establish an online charging session, the address of the home online charging function being from a policy and charging rules function; \n receive an online charging session response message from the home online charging function; \n establish the online charging session between the packet data network gateway and the home online charging function for the roaming subscriber; \n form a first charging information parameter list applicable to the roaming subscriber; \n send, to the home online charging function, a first quota request message carrying a rating group; \n receive a roaming data service quota from the home online charging function according to the rating group; and \n send first charging information to the home online charging function according to the first charging information parameter list, the first charging information comprising a usage of the roaming data service quota.
