INTER RADIO ACCESS TECHNOLOGY (IRAT) CELL RESELECTION

摘要

A method for cell reselection includes camping on a first cell in response to detecting the first cell during a first background search. The method also includes recording an IRAT cell reselection serving cell threshold and reselecting a second cell of a second RAT when the first cell of the first RAT is below the threshold and the second cell of the second RAT is above a threshold. The method further includes detecting a second cell of the first RAT in response to performing a second background search and comparing a signal quality of the second cell with a sum of the recorded threshold and a predefined threshold value. The method still further includes on the second cell when the signal quality of the second cell exceeds the threshold plus a predefined threshold.

1. A method of wireless communication, comprising:
camping on a first cell of a first radio access technology (RAT) in response to detecting the first cell during a first background search of the first RAT; recording an inter-radio access technology (IRAT) cell reselection serving cell threshold received from the first cell; reselecting to a second cell of a second RAT when the first cell of the first RAT is below the IRAT cell reselection serving cell threshold and the second cell of the second RAT is above an IRAT cell reselection neighbor cell threshold; detecting a second cell of the first RAT in response to performing a subsequent second background search of the first RAT; comparing a signal quality of the second cell of the first RAT with a sum of the recorded IRAT cell reselection serving cell threshold and a predefined threshold; and camping on the second cell of the first RAT only when the signal quality of the second cell exceeds the IRAT cell reselection serving cell threshold plus the predefined threshold.
