  • Patent number: 5999814
    Abstract: A method of handling oscillating mobile station handoffs between cells in a cellular telecommunications network. The method comprises the steps of detecting whether a mobile station (MS) is exhibiting an oscillating handoff pattern, determining whether the MS's signal strength with the MS's serving cell is above a safe signal strength threshold, and inhibiting handoffs of the MS upon determining that the signal strength is above the safe signal strength threshold. The oscillating handoff pattern is detected by first detecting a sequence of handoffs of the MS in which the number of handoffs is twice the number of cells involved in the handoffs, measuring an inter-handoff time period between each handoff in the sequence, and determining whether each inter-handoff time period is less than a first threshold value.
