Title: TIMER FOR AUTONOMOUS MOBILITY OF A COMMUNICATION DEVICE IN CELLULAR NETWORKS
Abstract:
A method comprising detecting at a communication device a measurement event in a network, initiating, triggered by the measurement event, transmission of a measurement report to the network for network-controlled handover of the communication device, starting, triggered by the measurement event, a timer, waiting for a handover command from the network instructing the communication device to perform handover to a network-selected target cell, initiating transmission of a handover request message to a device-selected target cell, if the timer expires before the handover command is received at the communication device transmission, adjusting the time until expiry of the started timer based on adjustment information obtained at the communication device, wherein the adjustment information is indicative of a probability for receiving the handover command before a radio link failure at the communication device occurs.
