Performance-based cell aggregation in a mobile network

摘要

For controlling aggregation of cells (101, 111, 112, 113, 114, 115, 116, 201, 211, 212, 213, 214, 215, 216) of a mobile network, a network management device (300) determines a traffic load of a cell (101, 111, 112, 113, 114, 115, 116, 201, 211, 212, 213 214, 215, 216) of the mobile network. Further, the network management device (300) determines a rate of handovers between the cell (101, 111, 112, 113, 114, 115, 116, 201, 211, 212, 213, 214, 215, 216) and at least one further cell (101, 111, 112, 113, 114, 115, 116, 201, 211, 212, 213, 214, 215, 216) of the mobile network. On the basis of the traffic load and the rate of handovers, the network management device (300) controls aggregation of the cell (101, 111, 112, 113.114, 115, 116, 201, 211, 212, 213, 214, 215, 216) and the at least one further cell (101, 111, 112, 113, 114, 115, 116, 201, 211, 212, 213, 214, 215, 216) to an aggregated cell.

主权项

1. A method for controlling aggregation of cells of a mobile network, the method comprising:
a network management device determining a traffic load of a cell of the mobile network; the network management device determining a rate of handovers between the cell and at least one further cell of the mobile network; on the basis of the traffic load and the rate of handovers, the network management device controlling aggregation of the cell and the at least one further cell to an aggregated cell that is managed by the mobile network as a single cell with respect to providing radio coverage to user equipments operating in the mobile network; and for the aggregated cell, the network management device:
determining a dominant cell of the aggregated cell;configuring a base station of the dominant cell as a donor base station; andconfiguring a base station or base stations of the other cell or cells in the aggregated cell as repeaters having backhaul connections to the donor base station.
