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: The present invention is directed towards providing event-triggered communication in a half duplex communication environment of a wireless communication network (10). A first end terminal (12) sends a selection of an end terminal (14) in a group of terminals to act as an event notifying device to a server (22). The event notifying device (14) compares an event with a threshold and sends an event notifier to the server if the event exceeds the threshold. If it receives the event notifier, the server prioritises data from the event notifying device over ongoing communication sessions for other devices in the group, receives data from the event notifying device associated with the event notifier and transports data indicative of the event to other devices of the group, in order to inform them of the event.
