Abstract: Embodiments of the present invention provide a cell management device and method. A data transmission delay between a coordinating cell and a serving cell is measured and compared with a requirement of a preset coordination manner for the data transmission delay, coordinating cells are managed by category according to the delay, a coordinating cell that satisfies the requirement of the preset coordination manner for the data transmission delay is identified, and then the coordinating cell that satisfies the delay requirement participates in coordinated communication of the cell with priority. Therefore, normal implementation of a coordinated function can be ensured, and an expected effect of the coordinated communication of the cell can be exerted. The device may be applicable to multiple networking cases and can be set flexibly, easily and conveniently.
