Abstract:
A method of tracking a service queue using a single-point signal monitor in which at least one customer carries a wireless device may include: receiving a received signal strength from the wireless device as a trace; identify first segments of the trace containing mostly positive sloped received signal strength; identify second segments of the trace containing mostly negative sloped received signal; extract attributes from the first and second segments as child variables for two parent nodes in a Bayesian Network in which the two parent nodes respectively model a beginning of service and a leaving period for a service queue; and inputting the extracted attributes into Bayesian Network; and determining a beginning of service and leaving period using the Bayesian Network. The method may also include determining critical time points in a trace using a K-L divergence technique.

Claim (Index 7):
The device of  claim 1 , wherein the attributes comprise R, S, L LP , C LP , L BoS , and C BoS , wherein:\n R=1 when a mean RSS before a specific segment of continuous negative slopes is the maximum of all segments of the trace, otherwise R=0; S=1 when a variation of RSS within a window W before a segment of continuous negative slopes is smaller than a threshold \u03c4, otherwise S=0; L LP =1 when a starting time of a specific segment of continuous negative slopes is later than a time where a maximum RSS value occurs, otherwise L LP =0; C LP =1 when an average slope of a specific segment of continuous negative slopes is the minimum of all segments of the trace, otherwise C LP =0; L BoS =1 when an end time of a specific segment of continuous positive slopes is earlier than a time where a maximum RSS value occurs, otherwise L BoS =0; and C BoS =1 when an average slope of a specific segment of continuous positive slopes is the maximum of all segments of the trace, otherwise C BoS =0.
