Cross-PLMN roaming data service online charging method and device

Abstract

The embodiment of the invention discloses a cross-PLMN roaming data service online charging method and device. The method comprises the steps that after it is judged that an access user is a roaming user, a visit location grouped data gateway sets up an online charging session for the access user and determines a first charging information parameter list according to the online charging session, then sends first quota request information carrying rate groups to an attribution location online charging system, and receives the roaming data service quota, sent by the attribution location online charging system, of the rate groups, and then first charging information is sent to the attribution location online charging system according to the first charging information parameter list, wherein the first charging information comprises the use amount of the roaming data service quota. According to the method and the device, the network connection of a visit location PGW and OCSs of other operators having roaming protocols with a visit location operator is simplified, the complexity of the network connection is reduced, and the efficiency of the network connection is improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an online charging method and device for cross-PLMN roaming data services. Background technique [0002] With the rapid development of mobile communication technology, the user's access to data services in the roaming state is increasing. At the same time, the home operator's online control of the roaming (roaming) user's consumption is also particularly important. [0003] The existing PCC (Policy Control Charging, policy control and charging) roaming architecture realizes the online control of the user's consumption when crossing the PLMN (Public Land Mobile Network, public land mobile network) through the Gy interface, that is, all the PGW (Packet Data Network Gateway, packet data gateway) needs to establish a connection with the OCS (Online Charging System, Online Charging System) of other operators that have roaming agreements with the visited operator through t...

[0003] The existing PCC (Policy Control Charging, policy control and charging) roaming architecture realizes the online control of the user's consumption when crossing the PLMN (Public Land Mobile Network, public land mobile network) through the Gy interface, that is, all the The PGW (Packet Data Network Gateway, packet data gateway) needs to establish a connection with the OCS (Online Charging System, Online Charging System) of other operators that have roaming agreements with the visited operator through the Gy interface. The number of OCSs of operators with roaming agreements in the visited places has caused problems of complex network connections and low efficiency

In addition, because the Gy interface of the visited PGW needs to be open, this makes it difficult to protect the network topology security of the visited place
