Charging in communication networks

摘要

A method for transferring charging information in a telecommunication system comprising a first network having a charging unit for collecting information on charges made to subscribers of the first network, a second network having a call charge generation unit for generating data records indicative of charges levied for calls, and a third network; the method comprising: determining that a call is to be established between a first terminal operating in the first network under a subscription to the first network and a second terminal operating in the third network under a subscription to the second network; transmitting from the first network to the call charge generation unit of the second network a charging address whereby messages may be directed to the charging unit of the first network; supporting the call between the first terminal operating in the first network and the second terminal operating in the third network; generating at the call charge generation unit of the second network a data record for charges levied by the second network for the call; and transmitting the data record to the charging address.
