Abstract
In a state where a mobile station UE is communicating with a radio base station S-eNB supporting 'extended PDCP-SN,' the mobile terminal continues communications even if it performs a reconnection procedure with a radio base station T-eNB not supporting 'extended PDCP-SN.' A mobile communication method according to the invention includes the steps of, when detecting RLF in the bearer in the above-described state, the mobile station UE resetting setting of “extended PDCP-SN” and establishing a bearer using “conventional PDCP-SN” by performing a reconnection procedure with a radio base station T-eNB not supporting “extended PDCP-SN.”
