Abstract: A method for detecting a malfunction in a cell of a telecommunication network is disclosed. The cell is adapted to serve a plurality of user devices identified by user identities and to handle signaling and/or data traffic between the network and the user devices. A lack of traffic is detected in the cell. Further, at least one user identity which identifies a user device is selected. The selected user device is served by the cell. Then a paging message is sent to the user device which is identified by the at least one selected user identity. Finally the malfunction of the cell is validated in case no response message is sent by the user device to said paging message.

Abstract: An exemplary method includes: receiving messages from plural positioning devices; decoding from a message received from a first positioning device information identifying a mobile device and a signal strength measure relating to a strength of a signal received from the mobile device at the first positioning device; using the signal strength measure to calculate a threshold signal strength; and distributing the threshold signal strength to the plural positioning devices. An exemplary apparatus and computer readable medium configured to perform the method are also disclosed.
