Billing in a packet switched communication system is based on the quality of service (QoS) associated with each session a user may be involved in or establish, separate from the physical circuits they consume. In the preferred embodiment, a session may be, but is not limited to, a voice connection, an internet connection or a video conference connection. This QoS measure may be combined with total packets exchanged during a session to arrive at a connection detail record. If such a packet switched communication system is coupled to an access network (145), such as a wireless communication system, the use of a single radio channel in the wireless communication system may result in the generation of several detail records based on the number of distinct sessions in which a user engages.
