Handover in a cellular radio system having several frequency ranges is problematic
e.g. from the viewpoint of network capacity utilization. The invention concerns
a handover-method, especially in a cellular radio system having at least two frequency
ranges, wherein the broadcasting is transmitted in a first frequency range and
handover to a second frequency range is started. The method according to the invention
is characterized in that bursts transmitted by the mobile station (MS) and relating
to the handover signalling are measured therein at the base transceiver station
(BTS), the measurement results are compared with a pre-established criterion and
handover is completed only when the criterion is met.
