CHARGING IN COMMUNICATION SYSTEMS

摘要

The present invention relates to charging of communications using chargeable resources of a first communication system and a second communication system wherein at least one of said communication systems provides wireless communication services. In accordance with the method, after a set-up procedure for communications initiated a first procedure for obtaining a fir st charging component is triggered, the first charging component being associat ed with the first communication system and determined based on a first charging model. If required, a second procedure for obtaining a second charging component is also triggered, the second charging component being associated with the second communication system and determined based on a second chargi ng model. Information associated with the communications in the first and secon d communication systems is processed simultaneously to obtain the respective first and second charging components. The first and second charging componen ts are combined to obtain a total charge. A prepaid balance is then decreased during the communications based on the total charge.
