SON CONTROL SYSTEM, SON CONTROL METHOD, AND MOBILE COMMUNICATION SYSTEM

摘要

A mobile communication system (100) in which a SON is implemented includes a load control unit (150). The load control unit (150) obtains D-SON apparatus information including at least a load state of the D-SON apparatus (190) from the D-SON apparatus (190) and also adjusts, based on the obtained D-SON apparatus information, a timing for instructing the D-SON apparatus (190) to execute the C-SON process so that a load on the D-SON apparatus is not concentrated on a time axis. In such a mobile communication system, it is possible to attempt to stabilize an operation of the entire SON even when the load on the D-SON apparatus is heavy.

主权项

1. A SON control system for performing SON (Self Organizing Network) control on a mobile communication system, the SON control being control based on a SON, the SON control system comprising:
a C-SON (Centralized-SON) apparatus that covers base stations from a plurality of vendors and performs a process for the SON control on the base stations that are covered; a D-SON (Distributed-SON) apparatus that covers one or more base stations from one vendor, performs the process for the SON control on the base stations that are covered, and performs a process including a C-SON process, the C-SON process including sending a report to the C-SON apparatus and a process instructed by the C-SON apparatus; and a load control unit that obtains D-SON apparatus information including at least a load state of the D-SON apparatus from the D-SON apparatus and adjusts, based on the obtained D-SON apparatus information, a timing for instructing the D-SON apparatus to execute the C-SON process so that a load on the D-SON apparatus is not concentrated on a time axis.
