Abstract
A method and device for decreasing the frequency of tracking area update (TAU) procedures triggered by cell reselections in LTE idle mode without sacrificing paging reception success rate consisting of identifying a frequency of a camped cell in LTE idle mode of a first SIM; assigning the current frequency a highest priority irrespective of the system information blocks (SIBs) broadcast by the network; and remaining on the current frequency until: a cell selection reception level value of the camped cell is less than a first predetermined threshold value or a cell selection quality value of the camped cell is less than a second predetermined threshold value.
