Inventor: CUFFARO ANGELO
IPC: H04W36/30
Filed: 1999-04-27
Abstract: 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.

Abstract: Accordingly, there is disclosed herein a method for radially profiling a property of a formation around a borehole that is suitable for combining measurements from multiple tools. In one embodiment, the method includes: (i) using a first downhole tool to obtain property measurements associated with multiple investigation depths; and (ii) determining from the property measurements estimated property values in predetermined radial zones.  The predetermined radial zones preferably include one zone that is the region of investigation by a second tool. This allows the estimated property value to be used in conjunction with any measurements by the second tool, or alternatively, provides a reference for calibrating the second tool. The estimated property values for the various predetermined radial zones are preferably those that minimize a distance metric value (e.g. the Euclidean distance) between the actual property measurements and the measurements expected to result from a formation profile having the estimated property values. The first downhole tool could illustratively be a resistivity tool, and the second downhole tool could illustratively be a nuclear magnetic resonance tool.
