Abstract: A mechanism of authenticating a communication device onto a radio access network via a private wireless gateway is described. This includes communicating with a communication device via a first wireless interface authentication information, a preferred roaming list (PRL), and an initial access value are obtained from the communication device.

The communication device is proxied onto a radio access network via a second wireless interface. The proxying includes providing the authentication information and the PRL to a cell site attached to the radio access network.

Abstract: A server device receives, from a user device, a session initiation request and information identifying a location of the user device, and receives, from a monitoring device that is separate from the user device, an authentication request and information identifying a location of the monitoring device.
