Method and apparatus for channel optimization during point-to-point protocol (PPP) session requests
First Claim
1. A packet data service node configured to simplify establishment of network protocol instances in a communication network, comprising:
- means for receiving a message when a mobile station moves from a first packet control function that serves a different packet data service node to a second packet control function that serves the packet data service node, wherein the message does not comprise any service reference identifiers;
means for establishing multiple network protocol instances in response to receiving the message; and
means for updating a connection table based on information in the message, wherein the updated connection table also does not comprise any service reference identifiers.

Abstract
A method and apparatus for requesting Point-to-Point Protocol (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 such 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). Communications channel resources of packet data services nodes are optimized by reducing the information included in messages from the Packet Control Function network element to the Packet Data Service Node network element, and by reducing the use of Mobile Internet Protocol agent advertisement.
