Abstract: A converged communication device comprises a first processor operable using a first communications protocol and a second processor operable using a second communications protocol. The first processor is configured to detect a factory reset. The factory reset selectively enables one of a multi-tier factory reset comprising: a factory reset of both the first and second processor; a factory reset of the first processor only; and a factory reset of the second processor only. The configuration may be triggered by an external input to the converged communication device.

Abstract: A method is provided that allows for prioritizing Push-To-Talk (PTT) service in a roamed network. PTT service is enabled for a mobile device at a first network. The mobile device roams to a second network that is of an older generation than the first network. It is determined that the mobile device has an active PTT subscription. PTT service is prioritized for the mobile device over circuit switched services on the second network.
