Abstract:
The present disclosure discloses a group charging method, a gateway device, a charging device, and a communications system, and relates to the field of communications technologies. The method includes: obtaining a group identity and personal identity information of a user; obtaining a charging rule generated according to the group identity; and establishing, according to the group identity, the personal identity information, and the charging rule, a charging session for a group account corresponding to the group identity, so that a charging system performs group charging according to the group identity and the charging rule. In the present disclosure, it is determined, according to a group identity of a user, that the user belongs to a certain group, and accordingly, a charging session is maintained for the user of the group. In this way, group charging can be achieved, thereby avoiding a complex signaling interaction process, and improving the charging efficiency.
