CELLULAR NETWORK ASSISTED WLAN DISCOVERY AND SELECTION
The systems, devices, and methods discussed herein are directed to a portable communication device, or a user equipment (UE), for discovering and accessing services through a wireless local area network (WLAN) that has not previously been provisioned for the UE without having a user of the UE provide credential information. To access services through an unprovisioned WLAN, the UE sends a request to its mobile network operator (MNO), and causes the MNO to request to, and receive from, the WLAN service provider the credential information for the UE, which is used to provision both the WLAN and UE.
