Wireless broadband communication method, device, and system to establish a bearer between a user equipment and a small cell

摘要

Embodiments of the present invention provide a wireless broadband communication method, device, and system, so as to increase bandwidth and capacity of mobile broadband communications and at the same time lower cost. The method provided in an embodiment of the present invention includes: establishing, by a macro base station, a Radio Resource Control RRC connection with a user equipment UE; receiving, by a small cell (small cell), a configuration message sent, through a wired or wireless interface, by the macro base station; and establishing, by the small cell, a user plane connection between the small cell and the UE based on the RRC connection and the configuration message, and establishing a data bearer with the UE on the user plane connection.

主权项

1. A user equipment comprising:
a transmitter; a processor, adapted to establish a Radio Resource Control (RRC) connection with a macro base station; and a receiver, adapted to receive an RRC reconfiguration message sent by the macro base station to a user equipment (UE) after the processor has established the RRC connection; wherein the processor is further adapted to establish a user plane connection with a small cell through an air interface based on the received RRC reconfiguration message, and establish a data bearer with the small cell on the user plane connection, wherein the data bearer only transmits user plane data between the UE and a core network (CN) element; and wherein the transmitter is adapted to:
transmit only control plane signaling through the established RRC connection to the macro base station; andtransmit the user plane data only via the data bearer to the small cell for sending the user plane data through the macro base station to the CN element, or transmit user plane data only via the data bearer to the small cell for sending the user plane data to the CN element.
