Abstract
A cell redirection process in accordance with load balancing and user terminal conditions, and a prompt cell reverting at the time of redirection failure are provided. A cell redirection control method under a situation where a base station controls two or more cells, the method comprising steps of: transmitting a response acknowledgement for a connection set-up to a redirected cell in accordance with a redirection instruction that instructs a redirection to another cell controlled by a base station and is transmitted from the base station at the time of an RRC connection in a user terminal; determining in the user terminal whether a connection to the redirected cell is successful within a range of a maximum number of retransmissions; and performing a reverting process for reverting back to an originating cell when the connection to the redirected cell fails, in the user terminal.
