UTILIZING SESSION INITIATION PROTOCOL FOR IDENTIFYING USER EQUIPMENT RESOURCE RESERVATION SETUP PROTOCOL CAPABILITIES

摘要

PURPOSE: A utilizing session initiation protocol for identifying user equipment resource reservation setup protocol capabilities is provided to provide a mechanism by way of indications and responses to negotiate instead of a resource reservation protocol mode of operation employing session initiation protocol. CONSTITUTION: A network includes a mobile unit and a proxy-call state control function unit. The mobile unit sends a session initiation protocol message to indicate a resource reservation protocol capability of the mobile unit such as media types to be transmitted, capabilities, and a preferred mode of operation. The proxy-call state control function unit, responsive to the session initiation protocol makes a decision as to whether the network or the mobile unit initiates resource reservation protocol signaling. The network transmits the decision to the mobile unit.
