Arrangement and method for optimising handling of handovers in telecommunication systems

摘要

An apparatus configured to operate in a telecommunications network comprising a first base station configured to serve at least a first cell and a second base station configured to serve at least a second cell, wherein said apparatus comprises a controller configured to receive measurements related to a successful handover of a user equipment from a first cell to a second cell, wherein said measurements relate to measurements being taken before and/or during said handover.

主权项

1. A network device having a processor and memory configured to operate in a telecommunications network, the network device comprising:
a controller configured to receive one or more reference signal measurements related to a successful handover of a user equipment from a first cell to a second cell, to estimate a probability of handover failure from the one or more reference signal measurements, to compare the probability of handover failure to a target failure rate, to change a hysteresis margin when the probability of handover failure exceeds the target failure rate, and to send an instruction based on the hysteresis margin to another device in the telecommunications network, the hysteresis margin specifying how much a target reference signal received power (RSRP) must exceed a source RSRP before a handover is triggered, wherein the one or more reference signal measurements are taken before and/or during the successful handover.
