Classification: CPC H | IPC H

Claim 9:
10. A communication system, comprising a first eNB, a second eNB and a UE (user equipment); wherein,
the first eNB maintaining an S1 connection with a core network is configured with a first downlink data transmission apparatus comprising:
processor circuitry configured to determine the second eNB, wherein,
the second eNB is required to schedule downlink data of the UE (user equipment) according to a paging area information of the UE and the second eNB according to information of the UE context uses indication information to determine transmission of the downlink data is a small data transmission; wherein, the indication information, the information of the UE context and information of the downlink data of the UE are included in a paging message transmitted to the second eNB via an interface between the first eNB and the second eNB, and,

the second eNB is configured with a second downlink data transmission apparatus comprising:
a receiver configured to receive the paging message transmitted by the first eNB;

processor circuitry configured to use the indication information to determine transmission of the downlink data is a small data transmission according to the information of the UE context; and
a scheduler configured to schedule the downlink data of the UE.
