Abstract

Appropriate 'idle mode cell reselection' is achieved by changing a threshold used to perform 'idle mode cell reselection' between a case of performing RSRQ measurement in six resource blocks and a case of performing “Wideband RSRQ measurement.” A mobile communication method according to the present invention includes a step of causing a radio base station eNB or a radio network controller RNC to broadcast not only existing parameters used to perform cell reselection processing based on a result of the RSRQ measurement in six resource blocks, but also wideband parameters used to perform “idle mode cell reselection” based on a measurement result of “Wideband RSRQ measurement.”
