Embodiments of the present invention relate to a charging method and device. The method includes: obtaining, by a radio access device located in an access network, first information, where the first information includes or is used to indicate a type of service data borne on a radio interface of the radio access device and a type of the radio interface; and sending, by the radio access device, the first information to a charging network element located in a core network, so that the charging network element performs charging by using the first information. The method provided in the embodiments of the present invention can implement service data charging without requiring a wireless local area network access gateway, thereby simplifying a communication process between network elements and reducing management costs of a network.
