    摘要： To further notify the amount of data retained in the transmission buffer used in a communication among a plurality of MOBILE STATIONs to a RADIO BASE STATION, the mobile communication method according to the present invention includes: transmitting, with a MOBILE STATION (UE#1), a BSR (#1) indicating the amount of data retained in a transmission buffer corresponding to a logical channel in a Uu interface to a RADIO BASE STATION (eNB) ; transmitting, with a MOBILE STATION (UE1), a BSR (#2) indicating the amount of data retained in a transmission buffer corresponding to a logical channel in a Ud interface to the RADIO BASE STATION (eNB) ; and distinguishing, with the RADIO BASE STATION (eNB), the BSR (#1) from the BSR (#2) based on predetermined information included in the received BSR.

    摘要： To conceal AC of a mobile station UE from an MMTEL/IMS layer function, and at the same time, perform SSAC barring in the MMTEL/IMS layer function. In the mobile station UE according to the present invention, an AS layer function 10 includes a broadcast information reception unit 11 configured to receive broadcast information, an adjustment unit 13 configured to generate second barring information (ac-BarringFactor and ac-BarringTime) based on first barring information (ac-BarringFactor and ac-BarringTime) included in the AC of the mobile station UE and the broadcast information, and a notification unit 14 configured to notify the MMTEL/IMS layer function 30 of the second barring information, and the MMTEL/IMS layer function 30 includes a determination unit 24 configured to determine whether or not it is possible to perform a call request process based on the second barring information.

    摘要： A mobile communication method according to the present invention includes the steps of: performing, at a mobile station UE which establishes a first connection in a first cell, a cell selection process at the time of detecting a failure in the first connection; transmitting, from the mobile station UE to a second cell selected in the cell selection process, a connection re-establishment request signal; determining, at a radio base station that manages the second cell, whether or not to store context information of the mobile station UE in response to the connection re-establishment request signal; acquiring, at the radio base station, the context information of the mobile station UE from a radio base station that manages the first cell, when determining that the context information of the mobile station UE is not stored; and (E) establishing a second connection in the second cell for the mobile station UE, based on the context information of the mobile station UE.

    摘要： A mobile communication method according to the present invention includes the steps of: transmitting, from an LTE-AS function to an EMM function, a reconnection request, when the LTE-AS function detects that an RRC connection is chanted to an idle state; and transmitting, at the EMM function, a service request, when the EMM function receives the reconnection request and detects that the LTE-AS function is in a coverage area.
