A method of handling oscillating mobile station handoffs between cells in a cellular telecommunications network. The method comprises the steps of detecting (1) whether a mobile station (MS) is exhibiting an oscillating handoff pattern, determining (32) whether the MS's signal strength with the MS's serving cell is above a safe signal strength threshold, and inhibiting handoffs (35) 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 (13) a sequence of handoffs of the MS in which the number of handoffs is twice the number of cells involved in the handoffs, measuring (14) an inter-handoff time period between each handoff in the sequence, and determining whether (15) each inter-handoff time period is less than a first threshold value. This is followed by determining an oldest handoff and a latest handoff in the sequence, measuring (23) a total oscillation time period between the oldest handoff and the latest handoff in the sequence, determining (24) whether the total oscillation time period is less than a second threshold value, and classifying (26) the MS as oscillating upon determining that the total oscillation time period is less than the second threshold value.
