Claim of US Patent No. 10,973,067

1. A first base station, comprising:a receiver configured to receive a first bearer setup request message initiated by user equipment (UE);
a transmitter configured to send a first tunnel endpoint to a core network device based on the first bearer setup request message, wherein the first tunnel endpoint comprises a first tunnel endpoint identifier (TEID) and a first transport layer address, the first tunnel endpoint is allocated by the first base station to indicate a destination of data transmitted in a downlink data transmission path of a first bearer;
wherein the receiver is further configured to receive a second tunnel endpoint from the core network device, wherein the second tunnel endpoint comprises a second TEID and a second transport layer address, the second tunnel endpoint is allocated by the core network device to indicate a destination of data transmitted in an uplink data transmission path of the first bearer; and
a processor configured to complete setup of the first bearer with the core network device for transmitting the uplink data and the downlink data, wherein the transmitter is further configured to send a radio resource control (RRC) connection setup complete message to a second base station to instruct the second base station to send an initial UE message to the core network device, wherein the RRC connection setup complete message and the initial UE message include the first tunnel endpoint.
