Patent ID: 8243647

Claim:
A radio access network apparatus comprising: a discontinuous reception management unit configured to manage a reception state of a discontinuous reception state or a continuous reception state for each of one or more mobile stations; a determination and announcement unit configured to determine and announce a correspondence relationship between a discontinuous reception channel and a shared data channel for each mobile station; and a scheduling unit configured to perform scheduling of a downlink shared data channel, wherein, when a paging signal to the mobile station in the discontinuous reception state occurs, the radio access network apparatus transmits the paging signal to the mobile station using the shared data channel determined based on the correspondence relationship, and, after the radio access network apparatus transmits the paging signal to the mobile station and a signal corresponding to a paging response is returned from the mobile station to the radio access network apparatus as a connection request, the radio access network apparatus performs downlink data transmission by using the shared data channel that is the same as the shared data channel used for transmitting the paging signal to the mobile station.
