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 14):
A method of managing access by a mobile device to a voice service located on a cellular network, the mobile device having a cellular network interface for accessing the cellular network via a radio access network and a wireless local area network interface for connecting to a wireless access point forming a wireless local area network, the wireless access point having a wide area network interface for accessing a public wide area network and a cellular gateway server located at a boundary between the public wide area network and the cellular network, the method comprising:\n at a gateway presence monitor located in the wide area network:\n accessing a first data store containing an identifier of the cellular gateway server and a wide area network address of the cellular gateway server; \n determining an availability of the cellular gateway server via the public wide area network; \n updating the first data store with the determined availability of the cellular gateway server; and \n sending at least a part of a contents of the updated first data store relating to the cellular gateway server availability to the wireless access point; and \n at the wireless access point:\n receiving an update from the gateway presence monitor relating to the cellular gateway server availability; \n accessing a second data store storing an identifier for the mobile device, a wide area network address of the associated cellular gateway server and an availability status of the cellular gateway server; and \n if the update from the gateway presence monitor indicates that the cellular gateway server is not currently available via the public wide area network, notifying the mobile device to access the voice service via the cellular network.
