Classification: CPC H  Y | IPC H

Claim 0:
1. A data transmitting apparatus, comprising:
processor circuitry configured to:
in a radio resource control (RRC) state other then an RRC_connected state, determine, based on a threshold of available data amount configured by a network device via broadcast, that
the RRC state other than the RRC_connected state is maintained and data is transmitted when an available data amount is less than or equal to the threshold, and
data is transmitted after entering an RRC_connected state when an available data amount is greater than the threshold; and

a transmitter configured to:
transmit, in the RRC state other than the RRC_connected state, data and a request message for entering the RRC_connected state to the network device only when it is determined to maintain the RRC state other than the RRC_connected state and to transmit data; and
enter the RRC_connected state and transmit data to the network device when it is determined to transmit data after entering the RRC_connected state, and

wherein in a case where the transmitter transmitted the data and the request message, the data transmitting apparatus is further configured to determine whether to maintain in the RRC state other than the RRC_connected state or enter the RRC_connected state according to a response message form the network device.
