Claim:
1. A method comprising: determining, by a user device, a signal condition of a signal received from a serving cell during a current wideband code division multiple access (WCDMA) idle mode; comparing the signal condition against at least three intra-frequency thresholds buckets corresponding to at least three intra-frequency rates of performing intra-frequency detections or measurements of neighboring cells for subsequent WCDMA idle modes; based on the comparing, selecting one of the at least three intra-frequency rates of performing the intra-frequency detections or measurements as follows: an initial intra-frequency rate when the signal condition is in a lowest of the at least three intra-frequency threshold buckets; a second intra-frequency rate when the signal condition is in a second lowest of the at least three intra-frequency threshold buckets, the second rate being a first fraction of the initial intra-frequency rate; or a third intra-frequency rate when the signal condition is in a third lowest of the at least three intra-frequency threshold buckets, the third intra-frequency rate being a second fraction of the initial intra-frequency rate, wherein the third intra-frequency rate is less than the second intra-frequency rate; comparing the signal condition against at least three inter-frequency thresholds buckets corresponding to at least three inter-frequency rates of performing an inter-frequency detections or measurements of neighboring cells for subsequent WCDMA idle modes; based on the comparing, selecting one of the at least three inter-frequency rates of performing the inter-frequency detections or measurements as follows: an initial inter-frequency rate when the signal condition is in a lowest of the at least three inter-frequency threshold buckets; a second inter-frequency rate when the signal condition is in a second lowest of the at least three inter-frequency threshold buckets, the second inter-frequency rate being a third fraction of the initial inter-frequency rate; or a third inter-frequency rate when the signal condition is in a third lowest of the at least three inter-frequency threshold buckets, the third inter-frequency rate being a fourth fraction of the initial inter-frequency rate, and wherein the third inter-frequency rate is less than the second inter-frequency rate.
