Abstract

In switching a radio base station (SeNB) from a radio base station (SeNB#1) to a radio base station (SeNB#2) in an “Inter-node UP aggregation”, forwarding of new downlink data destined for a mobile station (UE) from a radio base station (MeNB) to the radio base station (SeNB#2) is quickly started. A mobile communication method according to the present invention includes: sending, by the mobile station UE, the radio base station (MeNB) a “New data delivery request” that requests forwarding of new downlink data destined for the mobile station (UE) to the radio base station (SeNB#2), in response to an “SeNB change command”; and forwarding, by the radio base station MeNB, the new downlink data destined for the mobile station (UE) to the radio base station (SeNB#2), in response to the “New data delivery request”.
