Wireless Broadband Communication Method, Device, and System, for Establishing a User Plane Connection Between a Small Cell and a User Equipment

An apparatus, comprising:

• a processor, configured to establish a Radio Resource Control (RRC) connection with a second base station;
• a receiver, configured to receive an RRC reconfiguration message after the RRC connection is established;
• and
• a transmitter, configured to send a reconfiguration response message to the second base station;
• and
• wherein the processor is further configured to establish a first connection between the apparatus and a first base station based on the RRC reconfiguration message, wherein the first connection comprises one or more data bearers between the apparatus and the first base station, and the one or more data bearers transmit user data between the apparatus and a core network (CN) element.

A non-transitory computer readable medium storing a program for use by a user equipment (UE), wherein the program comprises instructions for:

• establishing a Radio Resource Control (RRC) connection with a second base station;
• receiving an RRC reconfiguration message after the RRC connection is established;
• sending a reconfiguration response message to the second base station;
• and
• establishing a first connection between the UE and a first base station based on the RRC reconfiguration message, wherein the first connection comprises one or more data bearers between the UE and the first base station, and the one or more data bearers transmit user data between the UE and a core network (CN) element.
