Abstract: The invention pertains to wireless service provision comprising reception or transmission of wireless signals from/to a communications system not (yet) available for public communications in an environment providing telecommunications services of another communications system. An example embodiment of the invention explores and implements triggering of a user equipment to perform test or measurement of a target network from an originating network, whereas the user equipment triggers establishment of a communications channel in the target network, the target network providing test signals to the user equipment.

Abstract: A hierarchical fault handling system and method based on filtering data regarding entities in the system and coordinating said filtered data in order to determined if an entity is considered faulty or not. The result for all entities is coordinated in a system fault coordinating means (17) which makes the overall decision if the system considered to be faulty or not.

Abstract: A hierarchical fault handling system and method based on filtering data regarding entities in the system and coordinating said filtered data in order to determine if an entity is considered faulty or not. The result for all entities is co-ordinated in a sys-tem fault co-ordinating means (17) which makes the overall decision if the system considered to be faulty or not.

Abstract: Equipment and/or functions at a node (e.g., base station) of a cellular telecommunications network are turned off or put into sleep mode during periods of low traffic in order to reduce power consumption by the node. The equipment and/or functions are then turned back on again during periods of high traffic load in order to provide the required service to users. Exemplary actions which can be taken in order to save power during the power saving mode include, for example and without limitation: 1) switching off or putting to sleep one or more MCPAs, 2) turning off one or more carriers, 3) turning off one or more sectors with regard to a frequency, 4) turning off or putting to sleep at least a portion or part of one or more circuit boards, and/or 5) reducing fan speed based upon traffic load of the node. Any one or more of these or similar actions may be taken in order to enable the node to save power when its traffic load is at a low level. Power consumption can thus be reduced.
