Abstract:
1. A cell reselection method for selecting a target cell in a cellular wireless communications system, comprising: observing over time signal characteristics of cells, the cells including at least potential target cells; observing a first indicator, which is indicative of the signaling level of a serving cell of the system, and observing second indicators, each one being indicative of a signaling level of one of the potential target cells; starting a timer for any potential target cell having a second indicator that indicates the signaling level of the respective potential target cell is better than the signaling level of the serving cell as indicated by the first indicator; determining that at least one timer has reached expiration; predicting, upon the expiration of the at least one timer, an indicator value at a future time for any cell having a running or expired timer, wherein the predicting is based on the observing of the second indicators; and delaying a cell reselection to a target cell to a time later than the expiration of the at least one timer if any potential target cell having an unexpired running timer has a best predicted indicator value at the future time.
