Abstract
A telecommunications system operable to provide a facility for mobile communications to a mobile device. The system comprises a core network, an access control function and a plurality of radio access networks. Each radio access network is operable to communicate data to and from the mobile device in accordance with one of a plurality of radio access technologies. In response to an attach request from the mobile device requesting a connection with the core network via a chosen radio access technology, the core network is operable to establish a connection with the mobile device via at least one of the plurality of radio access interfaces for communicating data to and from the mobile device. An access control function is operable to identify the mobile device requesting the connection with the core network and in accordance with access control criteria generate an attach response indicating with which if any of the plurality of radio access technologies the mobile device may establish the connection and communicate the attach response to the radio access network via which the mobile device has requested the connection.
