This disclosure is concerned with systems and methods for network communications. In one example, a cellular telecommunications network includes a radio access network with multiple geographically distributed cells, and further includes a core network for providing cellular telecommunications network functions to devices registered therewith over a cellular telecommunications network bearer. 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. Further, the core network is configured to receive 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.
