Abstract: A light-weight solution for media handovers between different Radio Access Technologies (RAT) is provided. A user may switch from Wi-Fi to Cellular Data (e.g., LTE/4G/3G/ . . . ), from Cellular data to Wi-Fi, and the like. In contrast to a “make-before-break” design for switching between RATs, the technologies described herein are a “break-before-make” design. When a change in a RAT is detected, an application on the computing device utilizing the connection is notified of the change. Instead of removing connection information, the connection is maintained for a configurable period of time such that the application can re-register with the network to continue the communication session. During a transition to a second RAT, the application provides one or more notifications to the user of the change in RAT. For instance, a graphical user interface (GUI) can be displayed showing the change and/or a tone can be played indicating the change in the RAT.

Abstract: A wireless telecommunications system provides location-specific call forwarding. The system can receive a request to connect a voice call to the wireless device, which can invoke a call forwarding procedure depending on a status of a subscriber associated with the wireless device. When the system determines that a current location of the wireless device is different from a default location, location-specific call forwarding information is used to forward the voice call to a terminating node associated with the location-specific forwarding information rather than a default terminating node for the default location. The terminating node can include a voicemail server that plays back a location-specific voicemail greeting to the caller.
