A method of charging a subscriber for using GPRS services provided by a mobile communications network. The method is based on including a flag in PDP activation or modification messages sent from a UE used by the subscriber to a GGSN of the network; the flag indicates whether the PDP context is to be used for signaling data or user data. The flag is examined within the network or at a node external to the network; if the flag indicates that the PDP context is to be used for carrying signaling data, a first charging regime is applied to the subscriber for establishing and using the context and, if the flag indicates that the PDP context is to be used for carrying user data, a different charging regime is applied to the subscriber for establishing and/or using the context.

Charging in a communications network

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.
