Abstract

An objective is to prohibit retransmission of “UE assistance information”. A mobile communication method according to the present invention includes the steps of: transmitting “UE assistance information” to a radio base station (eNB) by a mobile station (UE), the “UE assistance information” prompting the radio base station (eNB) to change a parameter for the mobile station UE used in the radio base station; notifying, by the radio base station (eNB), the mobile station (UE) of a transmission-prohibited period of the “UE assistance information”; and stopping, by the mobile station (UE), retransmission of the “UE assistance information” on the basis of the transmission-prohibited period.

Claims

1. A mobile communication method comprising the steps of:

transmitting mobile station assistance information to a radio base station by a mobile station, the mobile station assistance information prompting the radio base station to change a parameter for the mobile station used in the radio base station, wherein the mobile station assistance information includes a power saving preference for the mobile station;

notifying, by the radio base station, the mobile station of a transmission-prohibited period of the mobile station assistance information; and

stopping, by the mobile station, retransmission of the mobile station assistance information on the basis of the transmission-prohibited period, wherein the step of notifying the mobile station of a transmission-prohibited period comprises notifying the mobile station of a value indicating that the transmission-prohibited period is not permanently set.

2. A mobile station comprising:

a transmitter unit configured to transmit mobile station assistance information to a radio base station, the mobile station assistance information prompting the radio base station to change a parameter for the mobile station used in the radio base station, wherein the mobile station assistance information includes a power saving preference for the mobile station; and

a receiver unit configured to acquire a transmission-prohibited period of the mobile station assistance information from the radio base station, wherein the transmitter unit stops retransmission of the mobile station assistance information on the basis of the transmission-prohibited period, and

Wherein the receiver unit is configured to acquire a value indicating that the transmission-prohibited period is not permanently set.
