Abstract: Various exemplary embodiments relate to a session management node. A session management node may include: a receiver configured to receive an accounting message; a session information storage that includes a record of accumulated network usage of the subscriber; a session manager configured to determine a Quality of Service (QoS) for the subscriber based upon the subscriber's accumulated network usage and an update time; and a transmitter configured to send an authorization message to the NAS. A session management node may also include: a configurable NAS profile; a usage reporter; a policy engine; and a reauthorization scheduler. Various exemplary embodiments may relate to a method of authorizing QoS based on subscriber usage and current time period. The method may include: receiving an accounting message; monitoring the usage of the subscriber; authorizing a QoS; and transmitting an authorization message. Subscriber network usage may be associated with a monitoring key and/or rating factor.

Abstract: Various exemplary embodiments relate to a session management node. A session management node may include: a receiver that receives an accounting message indicating network usage of a subscriber, the message including at least one field; a NAS profile that maps the accounting message to a type of usage based on the field; a session information storage that includes a record of accumulated network usage for the type of usage; and a usage reporter that updates the subscriber's accumulated network usage. Various exemplary embodiments relate to a method of measuring network usage of a subscriber. The method may include: receiving an accounting message; determining a type of usage; and monitoring the subscriber's usage according to the type of usage. In various exemplary embodiments, various messages including vendor specific fields may be mapped to the same type of usage. A rating factor for monitoring may be assigned to a type of usage.
