Method and apparatus for performing roaming traffic charging for a ue

A method, at an alternative roaming provider, for performing roaming traffic charging for a user equipment, wherein the alternative roaming provider corresponds to a home network of the user equipment, the method comprising:

• receiving a roaming traffic charging request for performing roaming traffic charging for a user equipment, wherein the roaming traffic charging request includes roaming traffic-related information of the user equipment;
• performing match query in a user database based on the roaming traffic charging request to obtain roaming reservation information of the user equipment;
• performing the roaming traffic charging for the user equipment based on the roaming traffic-related information and the roaming reservation information.

An apparatus for performing roaming traffic charging for a user equipment, wherein the apparatus comprises:

• a first receiving device configured to receive a roaming traffic charging request about the user equipment, wherein the user equipment roams to a visited network, the roaming traffic charging request includes roaming traffic-related information of the user equipment;
• a request forwarding device configured to, if the roaming traffic-related information satisfies a first charging condition, forward the roaming traffic charging request to an OCS of an alternative roaming provider corresponding to the user equipment so as to perform the roaming traffic charging for the user equipment, wherein the alternative roaming provider corresponds to a home network of the user equipment.
