Abstract: An access point has a connection to a wide area network, and is configured to allow a device to connect thereto, and includes an Application Programming Interface for allowing a remote application to connect to the access point over the wide area network, and to obtain information relating to the device connected to the access point. In particular, the access point is configured to allow a device to connect thereto over a wireless interface, and to provide bearer translation such that traffic over the wireless interface can be directed over the wide area network. The Application Programming Interface may then allow the application to obtain information relating to a connection status of a wireless device associated with the access point.

Abstract: A base station for a cellular wireless communications network has a first interface, enabling connection with a remote communications device using a cellular wireless communications protocol in the cellular wireless communications network. The base station also has a second interface, enabling connection over a wide area network, and a third interface, enabling connection over a local area network. Software enables communication over the wide area network between a remote communications device, connected to the first interface, and a core network of the cellular wireless communications network. Software can also enable the remote communications device to communicate with a device in the local area network, or with a server in the wide area network, without using the core network of the cellular wireless communications network.

Abstract: A basestation, for example a femtocell basestation for use in a mobile communications network, has a frequency synthesizer, for generating signals at desired frequencies, and also has a wireless communications interface, for transmitting and receiving signals in the mobile communications network. The femtocell basestation also has a packet data interface, for transmitting and receiving packet data signals over a wide area network.

Abstract: A method of managing registration requests from unauthorized user equipments in a cellular communications network includes monitoring such further registration requests and maintaining a count of the total number of registration requests from said user equipment. Based on the counted number of unsuccessful registration requests, different mechanisms can be used to reject the registration request.

Abstract: A basestation in a cellular communications network is configured such that it has a different Location Area Identification from other local basestations in the cellular network. This has the effect that a Location Area Update procedure is performed when a mobile device wishes to camp onto that basestation. The basestation is able to configure itself automatically, to ensure that its Location Area Identification differs from other local basestations.

Abstract: 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.

Abstract: A basestation for cellular wireless communications network is able to configure itself for the operation in the network, by selecting appropriate operating frequencies (in the case of a GSM network) or scrambling codes (in the case of a UMTS network), and appropriate transmit powers. This makes it practical for a large number of such basestations to be deployed in a network, within customers' premises, without requiring network intervention in each case.

Abstract: A method for synchronising a clock signal in a basestation of a wireless telecommunications system is described. The basestation has a reference clock signal and is operable to communicate with wireless mobile terminals and with a packet switched network. The method comprises detecting a radio frequency clock synchronisation signal from a wireless telecommunications network, and synchronising the reference clock signal of the basestation in dependence upon the detected radio frequency clock synchronisation signal.
