Disclosed is a method of identifying interference in a cellular telecommunications network including a plurality of cells controlled by a base stations, each cell serving a plurality of mobile devicesby radio link by using communication resources allocated to each of the mobile devices, the network having a frequency band allocated thereto. The method includes detecting radio quality within the frequency band at at least one of the cells to produce measurement values; and analyzing selected ones of the measurement values to determine if the selected measurement values indicate the presence of interference, wherein the selected measurement values exclude the measurement values relating to the communication resources allocated to each of the mobile devices served by the cell.

Interference detection in mobile telecommunications networks

A GSM or UMTS mobile telecommunications network is provided including a radio access network comprising macro base stations with additional access points. The access points are connected to a network core via a hub and a concentrator and may appear to a mobile terminal as a conventional base station that communicates with the mobile terminal using GSM or UMTS protocols and does not require modification to a standard GSM or UMTS mobile terminal. The access points are associated as a cluster. A procedure includes performing initial configuration of the access points such that one or more of the access points operates in a transmit mode while the other access points operate in a receive mode only. The strength of the received signal is processed by a processor associated with the concentrator which calculates and provides parameters to each of the access points to provide optimum radio coverage within premises.

Configuration of access points in a telecommunications network

Configuring a cellular telecommunications network base station repeater for use at a particular location includes performing data collection activity at the location to obtain an indication of the transmit frequency of a nearby base station of the cellular telecommunications network. The repeater is then set to amplify received signals at that frequency. By only amplifying this particular frequency, the repeater can provide cellular telecommunications coverage at a location (for example a basement) where coverage might not otherwise be available by amplifying only the relevant frequency. This is in contrast to amplifying indiscriminately a wide range of frequencies, which can interfere with other radio transmissions.
