ORIGINATOR MOBILE DEVICE ASSISTED VOICE CALL TECHNOLOGY SELECTION

摘要

A smart Voice Over LTE (VoLTE) application for allowing a wireless mobile device to select an appropriate access technology for establishing a voice call with a target mobile device, based on the capabilities of the target mobile device. Selection on the client side allows interoperability of a VoLTE wireless mobile device on a circuit switched network without requiring use of a gateway between the circuit switched and VoLTE networks. If the target mobile device is only configured for legacy circuit switched network calls, the wireless mobile device need not begin the call connection on the VoLTE network and instead may establish the call on the circuit switched network from the beginning.

主权项

1. A method for selecting a network for originating voice call on a voice over IP (VoIP) capable mobile device, comprising:
receiving an input to initiate a voice call to a target mobile device; determining on the mobile device whether the target mobile device is capable of receiving a voice call on a VoIP network; and initiating the voice call on a circuit switched (CS) network in response to determining that the target mobile device is not capable of receiving a voice call on the VoIP network.
