Abstract: Systems and methods wherein the wireless device operates as a service control point (“SCP”) in a wireless service network. The billing system controls the service control point in the wireless device by periodically supplying increments of value from a master account balance. The billing system may also periodically update the service rules and authorizations maintained within the wireless device. Usage information such as call details records may also periodically be uploaded from the wireless device to the billing system. The service control function software in the wireless device and the billing system communicate with each other via administrative messages using over the air data bearer services of the network. The amount and frequency of the additional service authorizations and other communications vary, potentially on a service by service basis, depending upon the credit risks, fraud risks, user preferences, rate plans, available network resources, and other parameters.

Abstract: A method and system for rating a data communication session between a network and a wireless device is disclosed. According to an exemplary aspect of the method, the method monitors a series of events, namely, a setup event, a begin event and an end event, which take place during a communication session. The monitoring of such events is accomplished by a data rating application which resides on the wireless device. By monitoring such events, the data rating application is then able to rate the communication session using a number of rating methods. The rating method selected includes both how to meter the data transmitted during a data communication session and determine the rate to be applied to each metered increment. Examples of methods used to meter the data include time and volume. Different rating methods which can be used to rate the communication session include, for example, application, data utilization, source of data, data type, class of service, quality of service and transmission efficiency.
