摘要

PROBLEM TO BE SOLVED: To reduce the processing loads of a switching station MME when performing handover between radio base stations HeNB by a mobile station UE. SOLUTION: The mobile communication method includes: a step in which the mobile station UE transmits "Measurement Report" including the identification information "ECGI" of a cell subordinate to the radio base station HeNB and position registration area information "TAI" to the radio base station eNB; a step in which the radio base station eNB transmits "(X2)HO Request" including the identification information "ECGI" of the cell subordinate to the radio base station HeNB to the IP address of a gateway device HeNB-GW corresponding to the position registration area information "TAI"; and a step in which the gateway device HeNB-GW transfers the "(X2)HO Request" to the IP address corresponding to the identification information "ECGI" of the cell subordinate to the radio base station HeNB.
