PRIVATE ACCESS POINT CONTAINING A SIM CARD

摘要

An access point, or base station, for a mobile communications network, such as a cellular communications network, can be installed by a user, for use within or close to their own home or office. The base station has a SIM card, and can establish secure communications with the core network of the mobile communications network over the user's existing broadband internet connection. The base station is also able to obtain the necessary ciphering keys, in order to allow the mobile device to communicate securely with the base station, and hence with the core network.
