Embodiments of the present invention relate to the field of communications technologies, and disclose an identifier interaction method and a device, where the method includes: receiving, by a 3GPP access network entity, an identifier of a wireless local area network and priority information of the wireless local area network that are sent by a core network device, where the identifier of the wireless local area network is an identifier of a wireless local area network that a home area operator of user equipment allows the user equipment to access, and the 3GPP access network entity is a 3GPP access network entity in a roaming area in which the user equipment is located; and sending, by the 3GPP access network entity, the identifier of the wireless local area network to the user equipment according to the priority information of the wireless local area network. Implementing the embodiments of the present invention can enable the user equipment in a roaming state to select a wireless local area network that a home area operator and/or a roaming area operator of the user equipment allow/allows the user equipment to access. |
