MOBILE COMMUNICATION METHOD, RADIO ACCESS NETWORK APPARATUS, AND MOBILE STATION

摘要

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.”

1. A mobile communication method comprising:
a step A of causing a radio access network apparatus to broadcast not only existing parameters used to perform cell reselection processing based on a result of RSRQ (Reference Signal Received Quality) measurement in six resource blocks, but also wideband parameters used to perform cell reselection processing based on a result of RSRQ measurement in a bandwidth larger than six resource blocks; a step B of causing a mobile station capable of the RSRQ measurement in the bandwidth larger than six resource blocks to use the wideband parameters to perform the cell reselection processing based on a result of the RSRQ measurement in the bandwidth larger than six resource blocks; and a step C of causing a mobile station incapable of the RSRQ measurement in the bandwidth larger than six resource blocks to use the existing parameters to perform the cell reselection processing based on a result of the RSRQ measurement in six resource blocks.
