Abstract
Various embodiments are described herein to address the need for providing substantially reduced PTT call setup delays. Modifications to channel assignment request messaging (), such as an IS-2000 Reconnect Message and an IS-2000 Origination Message, are described. In addition, the use of common control channel signaling (e.g.,), changes to page response messaging (e.g.,) and new uses for A9-Short Data Delivery messaging (e.g.,and) are described. Embodiments incorporating some or all of these protocol changes, can provide reduced end-to-end call setup time for PTT as it presently exists in IS-2000 systems.
