A basestation for a cellular wireless communications network is able to configure itself for operation in the network, by selecting appropriate operating frequencies (in the case of 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.

Self-configuring cellular basestation

This invention relates to a cellular basestation, and in particular to a basestation for a cellular communications network, that can conveniently be used to provide a cellular service, for example within a home or office.

Local area cellular basestation

A basestation for a cellular communications system includes back-to-back software stacks for terminating messages from a mobile station intended for the core network, and for recreating the messages in a form suitable for transmission to the core network, and further for terminating messages from the core network intended for a mobile station, and for recreating the messages in a form suitable for transmission to the mobile station.

Basestation for cellular communications system

A basestationprovides coverage for voice and data services within a building using GSM/GPRS and UMTS interfaces within existing networks, allowing use of existing mobile phones. The basestation also provides flexible interfacing to the network operator's core networkvia the Unlicensed Mobile Access (UMA) standards as opposed to the usual Iub (UMTS) or Abis (GSM) interfaces used by conventional cellular basestations. Backhaul from the basestation units is achieved through the use of Digital Subscriber Line (DSL) connections over fixed telephone lines. This approach enables low-cost transport of data and voice using VoIP.

A basestation () in a mobile communications network is connected to the core network of the mobile communications network over a public wide area network. In the event of a handover between the basestation and another of the network nodes of the PLMW (), handover information () is sent between the basestation and the core network over the public wide area network, for example embedded in a SIP message or in a UMA message.

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.

Management of unauthorized user equipments in a femto base station environment

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.
