Abstract
The present invention is directed to a telephone billing management method for cellular telephones. The objective is to provide the user of a cellular telephone a cost accounting and management tool. The amounts of various classes of service used in the current billing period are downloaded and displayed at the user phone terminal, for instance on the wireless handset. Specifically, cumulative billing information for the present billing period is downloaded and displayed at the user's location during the call set up-period signalling period. The charge rate for the current call can also be downloaded. Once the call is stabilized, the duration (air time) and cost of the present call can be calculated and displayed in real time. Thus, for management purposes, the user has access to the provider's information on all charges up to the present call and the duration and cost of the present call can be calculated and displayed in real-time without further burden on the provider.
