Abstract
A method of routing Call Detail Records (CDRs) for a subscriber from a foreign network to a home network while the subscriber is roaming in the foreign network. The method comprises transferring from the home network to the foreign network during registration of the subscriber with an exchange of the foreign network, an address of a billing system of the home network in a signalling network to which said exchange and said billing system are coupled. Said address is associated with CDRs generated by said exchange in respect of the subscriber, and the CDRs transferred from said exchange to said billing system over said signalling network on the basis of the associated address.
