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

摘要

Embodiments of the present invention disclose a method for accessing a base station, a base station and a user equipment, belonging to the field of communications technologies. The method includes: establishing, by a current macro base station, a control plane connection with a user equipment according to an access request of the user equipment, and assigning a first cell-radio network temporary identity to the user equipment; and when receiving a measurement report of pico base stations reported by the user equipment, selecting 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 notifying context information of the user equipment to the pico base station, where the context information includes the first cell-radio network temporary identity assigned to the user equipment.

1. A method for accessing a base station, the method comprising:
establishing, by a current macro base station, a control plane connection with a user equipment according to an access request of the user equipment; assigning a first cell-radio network temporary identity to the user equipment; when receiving a measurement report of pico base stations reported by the user equipment, selecting 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 notifying 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; and judging, by the current macro base station according to the measurement report reported by the user equipment, whether to perform a base station handover, and if yes, instructing, according to types of a source base station and a target base station, the user equipment to hand over the data plane connection or the control plane connection to the target base station; wherein instructing, by the current macro base station according to the types of the source base station and the target base station, the user equipment to hand over the data plane connection or the control plane connection to the target base station, comprises: when the source base station and the target base station are both pico base stations covered by the current macro base station, maintaining, by the current macro base station, the control plane connection, and sending a first handover instruction to the user equipment, wherein the first handover instruction is used to instruct the user equipment to hand over the data plane connection between the user equipment and the source base station to the target base station; when the source base station is a pico base station covered by the current macro base station and the target base station is the current macro base station, maintaining, by the current macro base station, the control plane connection, and sending a first handover instruction to the user equipment, wherein the first handover instruction is used to instruct the user equipment to hand over the data plane connection between the user equipment and the source base station to the target base station; when the source base station is the current macro base station and the target base station is a pico base station covered by the current macro base station, maintaining, by the current macro base station, the control plane connection, and sending a first handover instruction to the user equipment, wherein the first handover instruction is used to instruct the user equipment to hand over the data plane connection between the user equipment and the source base station to the target base station; and when the source base station is the current macro base station, the target base station is a second macro base station, and the pico base station establishing the data plane connection with the user equipment crosses the current macro base station and the second macro base station, maintaining, by the current macro base station, the data plane connection between the pico base station and the user equipment, and sending a second handover instruction to the user equipment, wherein the second handover instruction is used to instruct the user equipment to hand over the control plane connection from the current macro base station to the second macro base station.
