Abstract:
1. A controlling node for a cellular communication system, comprising: a transmit unit, a receive unit, a processing unit, a memory unit, and an interface for an antenna, wherein the units and interface enable the controlling node to communicate with and handle control of one or more user terminals in a first cell, the controlling node being arranged to receive, via the antenna interface and the receive unit, certain transmissions from one or more user terminals in the first cell with a defined periodicity; and a receipt monitor for one or more user terminals in the first cell, wherein the receipt monitor is arranged to monitor timely receipt of one or more of the certain transmissions from the one or more user terminals at an expected time for the defined periodicity, and to initiate handover of a user terminal from the first cell to another cell if the controlling node does not receive one or more of the certain transmissions at the expected time for the defined periodicity from the user terminal.
