Method and device for charging traffic data flow of user equipment

A charging method for traffic data flow of UE, applicable to a system including a Packet data network Gateway (P-GW), a Mobile Edge Computing (MEC) server, and a Charging Gateway (CG), wherein the system further comprises a Mobile Edge Computing Gateway (MEC-GW) responsible for controlling charging for a local traffic, the MEC-GW is a logical and functional entity, and is deployed separately in a physical device, or can be deployed in a physical device together with a Serving Gateway (S-GW) and the P-GW which are responsible for generating and transmitting a charging data bill of a non-local traffic of the UE to the CG, the method comprising:

• receiving, by the MEC server, a request message transmitted by the MEC-GW to make a statistic of local traffic information of a User Equipment (UE), wherein the request message is transmitted by the MEC-GW to the MEC server upon reception of an instruction message transmitted by the P-GW to charge the UE for the local traffic;
• the request message comprises an identifier of the UE, a charging rule of the local traffic information, and an identifier of each IP-CAN bearer of the UE;
• determining, by the MEC server, the local traffic information of the UE to be reported, according to the request message;
• and
• making and then transmitting, by the MEC server, the statistic of the local traffic information of the UE to be reported, to the MEC-GW, so that the MEC-GW generates and then transmits a charging data bill of the local traffic of the UE to the CG according to the statistic of the local traffic information of the UE transmitted by the MEC server,
• wherein, the charging data bill comprises:
• the identifier of the UE, the identifier of the local area where the UE is served, the statistic of the local traffic information, the address of the P-GW, and the charging ID corresponding to each IP-CAN bearer of the UE.

• the request message comprises an identifier of the UE, a charging rule of the local traffic information, and an identifier of each IP-CAN bearer of the UE;
• and
• transmitting, by the CG, the charging data bill of the local traffic of the UE to a Business and Operation Support System (BOSS).

A charging apparatus for traffic data flow of UE, applicable to a system including a Packet data network Gateway (P-GW), a Mobile Edge Computing (MEC) server, a Charging Gateway (CG), and the charging apparatus, wherein the charging apparatus is a Mobile Edge Computing Gateway (MEC-GW) responsible for controlling charging for a local traffic, wherein the MEC-GW is a logical and functional entity, and is deployed separately in a physical device, or can be deployed in a physical device together with a Serving Gateway (S-GW) and the P-GW which are responsible for generating and transmitting a charging data bill of a non-local traffic of the UE to the CG, wherein the apparatus comprising at least one processor and a memory;

• wherein the memory is configured to store computer readable program codes, and the at least one processor is configured to execute the computer readable program codes to:
• determine that a user Equipment (UE) is to be charged for a local traffic;
• transmit a request message to the MEC server to make a statistic of local traffic information of the UE upon determining that the UE is to be charged for the local traffic;
• wherein, the request message comprises an identifier of the UE, a charging rule of the local traffic information, and an identifier of each IP-CAN bearer of the UE, and
• transmit a charging data bill of the local traffic of the UE to the CG;
• wherein, the charging data bill comprises:
• the identifier of the UE, the identifier of the local area where the UE is served, the statistic of the local traffic information, the address of the P-GW, and the charging ID corresponding to each IP-CAN bearer of the UE.
