Accounting system and method for a nominal bit rate network service
First Claim
1. A method of charging for usage of a connection between a network access node and a node of a network, comprising:
- transmitting cells of information over the connection in accordance with a nominal bit rate service comprising;
establishing a nominal bit rate service connection according to a request received by a network operator from a user for the nominal bit rate service connection;
measuring an actual bit rate of the connection for the nominal bit rate service connection; and
changing a probability of cell acceptance at the network node for the nominal bit rate service connection in response to a change in the actual bit rate relative to the nominal bit rate; and
computing a cost for usage of the connection based upon the established nominal bit rate service connection.

Abstract
A system and method for charging for usage of a network service connection. The network includes access nodes which provide user access to core nodes of the network. At an access node, the traffic of connections associated with the access node is measured. A nominal bit rate (NBR) associated with the access node is used together with the traffic measurement to compute a priority level at the access node. The value of NBR represents an expected, but not guaranteed, bit rate associated with a particular user or connection. The connection may be a real-time or a non-real-time connection. Information elements, transmitted from the access node to a core network node, are each assigned one of several priority levels, and cells are either accepted or discarded based on priority level and the status of one or more buffers at the core node. A charging schedule, based on a maximum allowed NBR established for the user, accounts for both a fixed or non-fixed monthly fee and a time dependent fee portion. The charging scheme may take into account that the NBR may be different for upstream and downstream transmissions. A charging counter, which accounts for the cost of connection usage, may be updated on a periodic basis, such as once a second for example, or on a non-periodic basis.
