MOBILE COMMUNICATION METHOD, MOBILE STATION, AND RADIO BASE STATION

摘要

A reconnection procedure is successfully performed even when a connection destination radio base station does not manage “UE Context” for a mobile station UE. A mobile communication method according to the present invention includes a step B in which the mobile station UE transmits CGI of cell #1 to a radio base station eNB#2 in the reconnection procedure, and a step C in which the radio base station eNB#2 acquires “UE Context” for the mobile station UE from a radio base station eNB#1 managing cell #1 designated based on the CGI when not managing “UE Context” for the mobile station UE in the reconnection procedure.

1. A mobile communication method comprising:
a step A in which when detecting a radio link failure in a first cell under a first radio base station, a mobile station starts a reconnection procedure for a second radio base station managing a second cell selected in a cell selection processing; a step B in which the mobile station transmits CGI of the first cell to the second radio base station in the reconnection procedure; and a step C in which in the reconnection procedure, when not managing context information of the mobile station, the second radio base station acquires context information of the mobile station from the first radio base station managing the first cell designated based on the CGI.
