METHOD AND APPARATUS FOR CHANNEL OPTIMIZATION DURING POINT-TO-POINT PROTOCOL (PPP) SESSION REQUESTS

摘要

PROBLEM TO BE SOLVED: To provide a method and apparatus for channel optimization during point-to-point protocol (PPP) session requests. SOLUTION: A method and apparatus for requesting PPP instances from a packet data services network includes a mobile station configured to send an origination message to a packet data service node (PDSN) at which it has arrived upon leaving the vicinity of another PDSN. The message informs the new PDSN of the new location of the mobile station and indicates both the number of dormant PPP instances associated with the mobile station and a service reference identifier for each PPP instance. A flag within the message may be used to indicate whether the PPP instances are dormant, i.e., whether the mobile station is engaged in a call. COPYRIGHT: (C)2011,JPO&INPIT
