Abstract
User equipment (UE) includes a transceiver configured to transmit and receive information to/from a Wireless Fidelity (WiFi) access point. The UE includes processing circuitry coupled to the transceiver and configured to: determine a service provider associated with the WiFi access point based on a response to an ANQP query. The UE is configured to receive at least a portion of a management object (MO). The MO includes a trust field specifying whether the WiFi access point is trusted for WiFi offload by the service provider. The UE is configured to: in response to determining that the WiFi access point is trusted, send an L3 attach trigger. The UE is configured to: in response to determining that the WiFi access point is not trusted, establish an Internet Protocol security (IPsec) tunnel that the UE to an Evolved Packet Data Gateway through the untrusted WiFi access point.
