Abstract
A system and method of controlling a VoLTE-capable vehicle telematics unit includes: detecting the location of the vehicle telematics unit; determining that one or more cell towers within a range of the location have begun supporting a modern cellular protocol in addition to one or more other cell towers supporting an earlier cellular protocol; and wirelessly transmitting an over-the-air (OTA) message to the vehicle telematics unit commanding the vehicle telematics unit to detach from an attached cell tower and re-attach to a cell tower using an IP multimedia subsystem (IMS) protocol.
