Abstract
Systems and methods of sending a secure user plane location (SUPL) session initiation message from a location platform to a SUPL-enabled terminal are provided. When a network-based application has an internet protocol (IP) connection with the SUPL-enabled terminal using general packet radio service (GPRS) and needs location information regarding the SUPL-enabled terminal, the network-based application indicates an available GPRS session in mobile location protocol standard location immediate request. The location platform uses an application server hosting the network-based application to request starting a SUPL-enabled terminal-initiated location procedure. Alternatively, the location platform can determine whether a SUPL-enabled terminal has an active IP connection from an authentication, authorization, and accounting server. The IP address of the SUPL-enabled terminal is returned to the location platform, upon which a SUPL session initiation message is sent to an associated GPRS Gateway Support Node. User Datagram Protocol is utilized instead of Wireless Datagram Protocol.
