METHOD AND DEVICE FOR SELECTING HETEROGENEOUS NETWORK SERVING CELL BASED ON INTER-CELL COOPERATION

摘要

A method and device for selecting a heterogeneous network serving cell based on inter-cell cooperation, which relate to the field of digital communications. The method disclosed in the embodiments of the present invention comprises: acquiring, by a central node base station in a heterogeneous network, alternative users in each cell in the heterogeneous network; and according to a pre-set alternative user selection criterion, selecting an alternative user in the entire network from the alternative users in all cells in the heterogeneous network; and if the alternative user in the entire network needs to conduct a reselection operation, initiating a cell reselection flow. Also disclosed is a device for selecting a heterogeneous network serving cell based on inter-cell cooperation corresponding to the method. In the technical solution of the embodiments of the present invention, cell selection and interference management are considered jointly, so that the complexity of an interference management algorithm is reduced, and the effectiveness of interference management is increased, thereby increasing the system capacity of a low-power node.
