Patent ID: 8849215

Claim:
A method comprising: performing, by a user device, a set of one or more measurements at an initial set of rates when the user device is in a discontinuous reception (DRX) mode, wherein the set of one or more measurements comprises an intra-frequency measurement for each of detected neighboring cells and an inter-frequency measurement for each of the detected neighboring cells; determining a signal condition of a signal received from a serving cell; and adjusting the initial set of rates based on the signal condition, wherein the adjusting the initial set of rates based on the signal condition comprises: comparing the signal condition against a first plurality of threshold levels for the intra-frequency measurement and selecting a corresponding rate from a first plurality of rates for the intra-frequency measurement based on the comparing, wherein the first plurality of threshold levels comprise at least three threshold levels that are defined from zero to a first initial threshold, S intrasearch , corresponding to a first initial rate of the initial set for the intra-frequency measurement; and comparing the signal condition against a second plurality of threshold levels for the inter-frequency measurement and selecting a corresponding rate for the inter-frequency measurement based on the comparing against the second plurality of threshold levels, wherein the second plurality of threshold levels comprise at least three threshold levels that are defined from zero to a second initial threshold, S intersearch , corresponding to a second initial rate of the initial set for the inter-frequency measurement.
