Abstract:
A VoWiFi service monitor monitors the logical data path to the ePDG of a MNO as an indication of whether VoWiFi service is possible for subscribers of the MNO network. Due to the standard configuration of UEs in preferring WLAN connectivity over LTE cellular connectivity, if the VoWiFi service is unavailable the UEs will not automatically switch to VoLTE while a WLAN connection is available between the UE and a hub. When a change in the status of an ePDG is detected, the VoWiFi service monitor informs any connected hubs. The hubs receive notifications from the VoWiFi service monitor and for each notification determine whether the ePDG status change affects one or more of the VoWiFi capable UEs connected to the hub. If at least one such device is affected by the change, the hub notifies the affected UE with instructions to handover from VoWiFi to VoLTE.

Claim (Index 1):
A method of operating a wireless access point to manage access of at least one mobile device to a voice service located in a cellular network, the voice service being accessible via a base station of the cellular network and also via a gateway server located at a boundary between the cellular network and a public wide area network,\n the wireless access point having a wireless network interface for communication with the at least one mobile device via a wireless local area network link, and a wide area network interface for communication with the public wide area network, and the at least one mobile device having a cellular network interface and a wireless network interface, wherein the at least one mobile device is configured to connect to the voice service via a first path from the at least one mobile device to the voice service via the base station and the cellular network, and a second path from the at least one mobile device via the wireless access point, the public wide area network, the gateway server and the cellular network, the method comprising:\n monitoring whether the at least one mobile device is currently connected to the voice service via the second path; \n processing presence information relating to the accessibility of the gateway server via the public wide area network; and \n if the at least one mobile device is connected to the voice service via the second path and the gateway server is not accessible via the public wide area network, instructing the at least one mobile device to connect to the voice service via the first path.
