  • Handover determination and power control adjustment in mobile communications systems with frequency hopping
    Patent number: 6778831
    Abstract: A device (5) for triggering a handover or for adjusting transmit power levels in a cellular communications system distinguishes between the use of a frequency hopping or a non-frequency hopping channel and sets a different threshold value depending on which type of channel is being used. In one embodiment, handover trigger levels for hopping channels are based on frame erasure rate measurements rather than bit error rate measurements thereby avoiding unnecessary handovers and advantageously reducing signaling traffic.
