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 15):
A system for managing access to a voice service by at least one mobile device, comprising:\n a cellular network for providing connectivity to the at least one mobile device, the cellular network having:\n a radio access network for communication with the at least one mobile device; \n a network core for routing data packets of the at least one mobile device; \n a cellular gateway located at a boundary of the cellular network and a public wide area network for access to the cellular network via alternate networks; \n a wireless access point having a wireless local area network connected to the at least one mobile device and further connected to the public wide area network; and \n a voice service associated with the cellular network and accessible via the cellular network and the public wide area network, \n wherein: the at least one mobile device is connected to the voice service via the wireless access point, the public wide area network and the cellular gateway; and the wireless access point is operable to:\n receive an update from a gateway presence server relating to cellular gateway availability; \n access a data store storing an identifier for the at least one mobile device, a wide area network address of the associated cellular gateway and an availability status of the cellular gateway; and \n if the update from the gateway presence server indicates that the cellular gateway is not currently available via the public wide area network, notify the at least one mobile device to access the voice service via the cellular network.
