1. A cellular telecommunications network, comprising: a radio access network comprising a plurality of geographically distributed cells; and a core network for providing cellular telecommunications network functions to devices registered therewith over a cellular telecommunications network bearer, wherein the cellular telecommunications network is adapted to provide core network cellular telecommunications network functions to devices registered therewith over a non-cellular telecommunications network bearer via another access network including a plurality of access points, and wherein said core network receives an identifier of said other access network when a device communicates with the core via an access point and selects a charge for providing telecommunications services in dependence upon the value of that identifier, the identifier of said other access network including the IP address of a mobile terminal; and wherein when the IP address of the mobile terminal changes, the change in IP address triggers the selection of a charge for providing telecommunications services.
