Mobile fast alerting
First Claim
1. A method of initiating an alert process by a wireless phone associated with the establishment of a wireless telephone call prior to completion of a signaling process associated with establishing the wireless telephone call, the method comprising the steps of:
- receiving, by the wireless phone, a session invite via a wireless packet subsystem of a wireless network, the session invite requesting establishment of the wireless telephone call with the wireless phone on the wireless network;
initiating establishment of a bearer circuit call by the wireless phone on a bearer channel of the wireless network; and
initiating the alert process, by the wireless phone, upon expiration of a first delay timer, the first delay timer starting upon receipt of the session invite by the wireless phone.

Abstract
Where a separate bearer channel is required to be set up in a mobile network to complete a hybrid VoIP call on the mobile network as specified in 3GPP ICS standard TR 23.892, an alerting process may be started after a provisionable delay rather than upon completion of the network call setup. This allows the mobile network user to start responding to the impending call before signaling of the call has been completed, so that the person can answer closer in time to completion of call signaling. Additionally, the person who placed the call may be provided with ringing feedback to make it sound like the call has been completed. The amount of delay between receipt of a SIP invite and the onset of an alerting process may be specified in the mobile handset or may be specified as a header in the SIP invite. The amount of delay may be fixed or adjusted based on feedback.
