Abstract
Systems and methods can support establishing a voice call over a wireless computer network between a mobile computing device and a second device, where the second device may be either another mobile device or a gateway for communicating to a traditional landline or mobile telephone. The connectivity status of the mobile computing device may be monitored. Call disruption indicators may be provided to the users in response to connectivity loss between the mobile computing device and the wireless computer network. Geographical location information associated with the mobile computing device may be collected in response to connectivity loss and a connectivity loss model may be generated. A connectivity-loss warning indicator may be provided to the users based upon a proximity metric of the geographical location associated with the mobile computing device and the connectivity loss model.
