Abstract: A basestation in a cellular communication system corrects frequency errors in signals generated within the basestation. The frequency errors may be corrected on the basis of signals transmitted by one or more other basestations within the network. As an alternative, the basestation may request information from one or more mobile devices that are also able to detect transmissions from other basestations.

Abstract: In a cellular communications network, it may be desirable for a large number of basestations to share one or a small number of scrambling codes. When a basestation identifies a desired scrambling code, which is also being used by another nearby basestation, steps are taken such that a location area update is triggered whenever a mobile communications device moves from a coverage area of the nearby basestation into a coverage area of said basestation. Further, the basestation establishes a first cell, using the desired scrambling code, and also establishes a second cell also served by the basestation, using a second scrambling code. By ensuring that mobile devices are preferentially served by the second cell, the possibility of interference with the nearby basestation is reduced.

Abstract: A basestation, for use in a cellular communications network, is adapted to provide a cellular communications service in at least one active cellular communications network by transmitting signals on system downlink channels of the active network and by receiving signals on system uplink channels of the active network. The basestation is also adapted to receive signals on system downlink channels of the active network. Further, the basestation is adapted to receive signals on system downlink channels of at least one additional network, although it is unable to transmit signals on system downlink channels of the additional network. The additional network may operate in accordance with a different cellular standard from the active network, and/or may be operated by a different cellular network operator from the active network.

Abstract: In a femtocell basestation of a cellular communications network, there is a potential difficulty that the basestation may be unable to select a scrambling code for its transmissions, without the risk of interference with other basestations using the same scrambling code. The femtocell basestation receives from a management system a list comprising at least one allowed scram-bling code for femtocell basestations, and also detects, in information broadcast by at least one macrocell basestation, at least one allowed scrambling code available in an area containing the basestation. If it is determined that use of each scrambling code that is allowed and is available in an area containing the basestation would cause interference with another femtocell basestation, a pa-rameter is set to ensure that a user equipment would perform a location update when moving between the coverage areas of said basestation and the other femtocell basestation. The parameter may be a MIB and/or SIB value tag.

Abstract: A neighbour cell list is formed, for use in a basestation of a cellular communications network. For each of a plurality of neighbour cells, a value of a first component is assigned, depending on whether or not the basestation can detect signals transmitted from said neighbour cell. A value of a second component is assigned, depending on a history of successful or unsuccessful handover attempts to said neighbour cell. The values of the first and second components are combined to form a weighting parameter, for use in determining a handover priority to be given to said neighbour cell in the neighbour cell list.

Abstract: A basestation forms part of a group of basestations within a cellular communications network, and selects an identifying code for use in identifying transmissions from the basestation. The basestation receives from a management node a first list of identifying codes and a second list of identifying codes, wherein the identifying codes of the first list can appear in neighbour cell lists of basestations outside said group, and wherein the identifying codes of the second list can not appear in neighbour cell lists of basestations outside said group. The basestation determines whether there is at least one identifying code either in the first list of identifying codes or the second list of identifying codes that is not used by any other basestation in said group.

Abstract: A cellular access point, amongst a plurality of interconnected cellular access points receives from a first user equipment a connection attempt that would cause the access point to exceed a first predetermined capacity threshold. The cellular access point selects one of the previously connected user equipments and an associated one of the plurality of interconnected cellular access points. The cellular access point initiates a handover of the selected one of the previously connected user equipments to the associated one of the plurality of interconnected cellular access points and establishes a connection with the first user equipment.

Abstract: A downlink power is set for transmissions from a basestation of a cellular communications network, the cellular communications network comprising a group of such basestations. A target value for a signal strength with which the transmissions should be received, and a target value for a pathloss, based on measured values for pathlosses between basestations of the group, are both set. The downlink power is calculated, based on the target value for the signal strength, and on the target value for the pathloss.

Abstract: A basestation, for use in a cellular communications network, has a mechanism for reporting its transmit power. When the transmit power of the basestation is outside a reportable range, it reports an adjusted transmit power within the reportable range, and also transmits an adjustment factor, by which the adjusted transmit power differs from the transmit power. The basestation is also configured to adapt its power settings based on a reported transmit power of at least one other basestation, and is further configured to detect the reported transmit power of the at least one other basestation and to detect an adjustment factor transmitted separately by the at least one other basestation, and to adapt its power settings based on a sum of the reported transmit power and the adjustment factor.

Abstract: A base station in a cellular network, such as a femtocell access point, has a first coverage area, and is located in a second coverage area associated with a second base station. The base station operates to detect a possibility of interference based on estimated first path losses, between the base station and points in the first coverage area, and a second path loss, between the base station and a user equipment that is attached to the second base station.

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 cellular basestation, for example a femtocell basestation, is able to configure its cel reselection parameters, in order to define a desired transition zone, in which cell reselections may take place. Specifically, the basestation detects broadcast cell reselection parameters of at least one neighbouring basestation, and adapts its own broadcast cell reselection parameters in response to the detected broadcast parameters of the neighbouring basestation.

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: 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: A basestation, for a cellular communication network, is described. The basestation is adapted to store a list of user equipments that are authorized to access the network by means of the basestation. In the event that the basestation receives a location update request from an unauthorized user equipment, the basestation is adapted to send a reject message to the unauthorized user equipment. The reject message specifically identifies the basestation, such that the unauthorized user equipment does not attempt to send any further location update request to the basestation.

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.
