Abstract
A system includes a session border controller (SBC) coupled to an internet protocol (IP) multimedia core subsystem (IMS) of a telecommunications network. The SBC obtains information indicative of a roaming profile of a particular subscriber associated with the telecommunications network. The roaming profile indicates geographic areas in which the particular subscriber is authorized to access a communications service. The SBC receives a request to connect a particular voice call over a Wi-Fi network from a wireless device on the telecommunications network. The wireless device is associated with the particular subscriber to the telecommunications network. The SBC identifies a current location of the wireless device and compares the current location of the wireless device with geographic areas in which the particular subscriber is authorized to access the communications service. The SBC can then enable or deny the IMS to establish a session for the particular voice call over the Wi-Fi network.
