METHOD, SYSTEM AND TELECOMMUNICATION NODE FOR ALTERNATIVE PREPAID SUPPORT

摘要

A method and system for providing alternative prepaid service when a serving Packet Data Service Node (PDSN) does not support prepaid or at least the typ e of prepaid the user has subscribed to. The serving PDSN sends an access request to a Home Authorization, Authentication & Accounting Prepaid Ser ver (HAAA/PPS) with an indication of its capability to support prepaid service a nd to terminate sessions based on requests from remote nodes. When the serving PDSN is neither capable of prepaid service, nor does it support session termination by a remote node, the HAAA/PPS determines that a prepaid session is allowed and supported in combination with a Home Agent (HA) for duration- based prepaid service. When the PDSN is not prepaid capable but supports session termination capability, the HAAA/PPS determines that any type of prepaid service can be allowed and supported by the HAAA/PPS in combination with the HA.
