Abstract: An LAA-LTE wireless device obtains data to be transmitted in subframes over a shared spectrum. The wireless device transmits a reservation message over the shared spectrum. The reservation message indicates that an initial synchronization message will be retransmitted a specified number of times at specified intervals, such as with a predetermined number of subframes between each retransmitted synchronization message. The wireless device transmits the initial synchronization message over the shared spectrum.

Abstract: A wireless device accesses a shared spectrum equitably in a self-organizing manner by determining success indices and adjusting courtesy parameters. The wireless device transmits wireless transmissions in a frame subframe structure over a shared spectrum, each of the subframes bounded by subframe boundaries at predetermined time intervals. The success index represents a measure of success in transmitting wireless transmissions in the shared spectrum. The wireless device performs a clear channel assessment to determine whether the shared spectrum is available at the end of the clear channel assessment time interval. The wireless device determines a gap interval between the end of the clear channel assessment time interval and the next subframe boundary and transmits the success index during the gap interval.

Abstract: 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.

Abstract: 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.

Abstract: A basestation 110 provides 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 network 130 via 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.

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: Methods of operation of an access point are disclosed. These methods may involve authenticating a user equipment device in the access point. Access points configured for operating in accordance with the methods are also disclosed. Additionally, methods of operation of user equipment devices, and user equipment devices themselves configured for operating, in conjunction with the access points are disclosed. Still further, core network nodes configured to operate with the access points are disclosed.

Abstract: A wireless access device is operable in a mode in which its maximum transmit power is set to a value that means that the device has a range of less than 1 metre. This allows the device to operate as a basestation in a cellular communications network, even in locations in which it is not specifically licensed, because the power level is so low that it will not cause interference on the licensed frequencies. The wireless access device is designed such that a handheld portable device can be maintained in a close spatial relationship to it.

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 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.
