Method for accessing base station, base station, and user equipment

A method for accessing a base station, the method comprising:

• establishing a control plane connection with a macro base station, and receiving a cell-radio network temporary identity assigned by the macro base station;
• and
• reporting monitored measurement reports of pico base stations, accessing a pico base station selected by the macro base station according to the measurement report of the pico base stations, and establishing a data plane connection with the pica base station selected by the macro base station, wherein the pico base station obtains the cell-radio network temporary identity of a user by receiving context information of a user equipment forwarded by the macro base station.

A base station comprising:

• a control plane connection establishing module, configured to establish a control plane connection with a user equipment according to an access request of the user equipment, and assign a first cell-radio network temporary identity to the user equipment;
• and
• a first identifier maintaining module, configured to, when receiving a measurement report of pico base stations reported by the user equipment, select a pico base station for the user equipment according to a preset policy so that the user equipment establishes a data plane connection with the pico base station, and notify context information of the user equipment to the pico base station, wherein the context information comprises the first cell-radio network temporary identity assigned to the user equipment.

A user equipment, comprising:

• a first connection establishing module, configured to establish a control plane connection with a macro base station, and receive a cell-radio network temporary identity assigned by the macro base station;
• and
• a second connection establishing module, configured to report a monitored measurement report of pico base stations, access a pico base station selected by the macro base station according to the measurement report of the pico base stations, and establish a data plane connection with the pico base station selected by the macro base station, wherein the pico base station obtains the cell-radio network temporary identity of a user by receiving context information of the user equipment forwarded by the macro base station.
