Embodiments of the present invention provide a base station, a network system, and a communication method. The base station includes: a control module, configured to connect to a control module of at least one other base station by using a first logical interface, and perform control plane interaction during inter-base station coordination; and a data processing module, connected to the control module, and configured to connect to a data processing module of the at least one other base station by using a second logical interface, and perform user plane interaction during the inter-base station coordination. The base station in this embodiment of the present invention is provided with the first logical interface and the second logical interface to respectively implement the control plane interaction and the user plane interaction between base stations, so that the inter-base station coordination can be implemented. |

1. An inter-base station coordination communication method, comprising:
receiving, by a first base station, an activate cell command sent by an element management system (EMS); activating, by the first base station, a first cell according to the activate cell command; sending, by the first base station, a cell state report message of the first cell to a second base station by using a first logical interface, wherein the cell state report message of the first cell belongs to a control plane packet used for inter-base station coordination, the cell state report message of the first cell carries information of the first cell of the first base station, so as the second base station stores the information of the first cell, the first base station and the second base station are both independent base stations; receiving, by the first base station, a cell state report message of a second cell sent by the second base station by using the first logical interface, and storing information of the second cell, wherein the cell state report message of the second cell belongs to the control plane packet used for inter-base station coordination, the cell state report message of the second cell carries the information of the second cell of the second base station, the second cell is activated by the second base station according to an activate cell command received from the EMS; and exchanging, by the first base station, a user plane packet used for inter-base station coordination, with the second base station by using a second logical interface after the first cell and the second cell are both activated, wherein the first logical interface and the second logical interface are both different with S1 interface and X2 interface. |
