Abstract
In a WCDMA UTRAN system, the amount of data on a DCH is suppressed. In the system disclosed herein, nodes Band Bwhich communicate with a UEvia a point Uu and an RNCwhich communicates with a CNthrough a point Iu are connected via a point Iub, a normal or silent mode is used for the DCH in the uplink side in the direction from the nodes B to the RNC, and the normal mode is used for the DCH in the downlink side in the direction from the RNC to the nodes B. In this system, a semi-normal mode is provided in which: when a no-data frame is received from the RNC, the nodes B do not transmit data to the UE; when data is not received from the UE, the nodes B transmit a no-data frame to the RNC for every plural TTIs; when data is not received from the nodes B, the RNC does not transmit data to the CN; and when data is not received from the CN, the RNC transmits a no-data frame to the nodes B for every plural TTIs.
