ORIGINATOR MOBILE DEVICE ASSISTED VOICE CALL TECHNOLOGY SELECTION

摘要

A smart Voice Over LTE (VoLTE) application that enables a wireless mobile device to select an appropriate access technology to establish a voice call to a target mobile device based on the capabilities of the target mobile device. The choice on the client side allows interoperability of VoLTE wireless mobile devices on circuit switched networks without requiring the use of gateways between the circuit switched and VoLTE networks. If the target mobile device is solely configured for legacy circuit switched network calls, the wireless mobile device does not need to initiate a call connection on VoLTE, but instead may establish a call from the start on the circuit switched network.
