Provided in an embodiment of the present invention are a gateway selection method, device and system, comprising: when a user equipment (UE) is roaming, accessing an MME allocated by an operator of a visited location and sending a data service request to the gateway corresponding to the MME; the gateway relocates the request to a roaming support system, and the roaming support system provides alternative roaming service providers (ARP) for the UE; the UE selects a first MVNO and signs a contract online with the roaming support system for the first MVNO; the roaming support system notifies a network management device to instruct the MME to select the MME serving the first MVNO and the corresponding gateway for the UE. Alternatively, the UE sends an access request carrying special APN information to the MME indicating that the UE is a subscriber of the first MVNO, such that the MME selects the MME serving the first MVNO and the corresponding gateway for the UE after the UE accesses the MME. Thereby, a suitable gateway can be allocated to the MVNO selected by the roaming UE in the network of the visited location under different scenarios. |
