A method and apparatus for session release in a communication system supporting Internet Protocol IP communications. In one embodiment, when the MS has lost a bearer connection i.e., PPP session, the notification is provided by a Packet Data Service Node PDSN 112 to the serving Session Control Manager SCM via IP multicast. If two PPP sessions are active for a given IP communication, and one PPP session is not lost, the PDSN associated with the active PPP session sends a correction message to ignore any notification message sent by the other PDSN. In an alternate embodiment, the Authentication Authorization Accounting AAA server uses start and stop accounting requests, received from PDSNs, to determine when to notify the serving SCM to terminate an IP communication. |
