Abstract:
1. A network that provides a push service while conserving network resources including a PPP state and an A10 connection, comprising: a wireless terminal having an IP address associated therewith; a first packet data serving node that, responsive to wireless terminal profile information, creates reachability information for the wireless terminal; a first radio access network that generates a dormant indication upon detecting that the wireless terminal is dormant, an Access Network Authentication, Authorization and Accounting (AAA) server, wherein the first packet data serving node receives wireless terminal profile information from the Access Network Authentication, Authorization and Accounting (AAA) server if the wireless terminal is authenticated; a PCF, and wherein if a access-network Challenge Handshake Authentication Protocol authentication is successful, the Access Network AAA server assigns a temporary IMSI and conveys the temporary IMSI to the PCF via RADIUS Access-Accept such that the PCF can include the IMSI in A11 signaling to the packet data serving node; and wherein, upon receiving the dormant indication, the first packet data serving node removes the PPP state and requests that the first radio access network release the A10 connection.
