Abstract: A conversation is handed over between an unlicensed data network and a cellular network. Voice conversations and/or video conversations may be seamlessly transitioned between cellular networks and unlicensed data networks (e.g., Wi-Fi), with a small transition time (e.g., less than a couple of seconds). The handover may occur from the unlicensed data network to the cellular network or from the cellular network to the unlicensed data network. During the transition between networks, cached registration data is accessed to speed up the authentication of the computing device switching networks. In some configurations, a user may specify preferences for switching between the unlicensed data and cellular networks. For instance, a user may specify a preference to use Wi-Fi networks before cellular networks or to use cellular networks before using Wi-Fi networks.

Abstract translation: 会话在非授权数据网络和蜂窝网络之间切换。 语音对话和/或视频对话可以在蜂窝网络和非许可数据网络（例如，Wi-Fi）之间无缝地转换，具有小的转换时间（例如，少于几秒）。 切换可以从非许可数据网络发送到蜂窝网络，或者从蜂窝网络发送到非许可数据网络。 在网络之间的转换期间，访问缓存的注册数据以加速计算设备交换网络的认证。 在一些配置中，用户可以指定在未许可数据和蜂窝网络之间切换的偏好。 例如，用户可以指定在蜂窝网络之前使用Wi-Fi网络的优选或者在使用Wi-Fi网络之前使用蜂窝网络。
