Abstract: A system for restricting access to a mobile communications network by mobile communications devices within a restricted area includes one or more transmitters, one or more designated test mobile communications devices, and an access control entity. The access control entity is arranged to determine, using first measurement data received from one of the designated test mobile communications devices, whether one of the one or more transmitters is positioned correctly and functioning correctly for restricting the access to the mobile communications network by the mobile communications devices in the restricted area. The access control entity is further arranged to decide, based on second measurement data received from a second mobile communications device which is not a designated test mobile communications device, whether or not to provide the second mobile communication device with access to a service of the mobile communications network.

Abstract: There is described a system for restricting access to a mobile communications network for mobile communication devices within a restricted area. The system includes at least one transmitter operable to transmit a beacon signal for reception by mobile communication devices within the restricted area and an access control entity, communicable with the mobile communication device via a base station. The access control entity instructs a mobile communication device to perform at least one measurement of the beacon signal from each transmitter and then to provide measurement data corresponding to the performed measurement to the access control entity. The access control entity then analyses the measurement data provided by the mobile communication device and based on that analysis decides whether or not to provide the mobile communication device with access to a service of the mobile communications network.

Abstract: Wireless communication apparatus is disclosed having a first base station providing an access point to a first communications network and second base station providing an access point to a second communication network. The first base station communicates wirelessly with a first access terminal using a first carrier at a first frequency and having a first bandwidth, and the second base station communicates wirelessly with a second access terminal using a set of carriers at respective different frequencies within a second frequency band, which has a second bandwidth larger than the first bandwidth and the first frequency is within the second frequency band. The second base station inhibits transmission of data by the second base station to the second access terminal using a subset of carriers having frequencies within the first bandwidth of the first frequency.

Abstract: There is discussed a location system for locating the position of a mobile communications device that communicates with a communication network using wireless signals. The location system includes a receiver which detects a wireless signal transmitted between the mobile communications device and a base station forming part of the communication network, and a processing means which processes the detected wireless signal to extract identification information for the mobile communications device. The extracted identification is stored in a data store in association with data indicative of the base station. The processing means and the data store are independent from the communication network, and therefore do not affect the operation of the mobile network.

The first network device receives from the second network device an indication of the time difference between reception of the first data over the first network link and reception of the second data over the second network link.

Abstract: Abstract of the Disclosure In a telecommunications system such as a global mobile telephone network in which each subscriber unit includes a Subscriber Identity Module (SIM card), each SIM card has fixed memory locations, to which data can be addressed over the air. Some of the locations can not be overwritten from the subscriber unit but can be accessed therefrom on the entry of short simple codes, each associated with one of the locations. Further fixed memory locations can be read over the air only when the subscriber enters a personal identification number. Locking control files are used to control read/write access to the locations respectively.
