When configuring Hotspot2.0 services, configure network parameters according to operator requirements. When connecting to networks, user terminals can obtain the network parameters to select desired networks. If the user terminals need to roam among Hotspot2.0 networks of different operators, configure a roaming consortium profile and add the organization identifiers (OIs) of the operators to the roaming consortium profile. In this way, after the user terminals connect to a network of an operator in the profile, they can roam to networks of the other operators while maintaining online.
