More Information
Summary:Techniques are disclosed relating to handover of WLAN voice calls to one or more cellular networks. In some embodiments, a device is configured to perform voice communications over one or more wireless local area networks, communicate with a first network using a first cellular radio access technology (RAT), and communicate with a second network using a second cellular RAT. The device may store, based on communications via the first network, information indicating that the first network does not support voice communications for the apparatus. The device may handover a voice call from a wireless local network directly to the second cellular RAT, based on the stored information and without handover of the voice call to the first cellular RAT, based on call conditions on the wireless local area network.
