Radio access system and radio control apparatus

摘要

A radio access system including a plurality of radio apparatuses each configured to forma cell, and a radio control apparatus to control the plurality of radio apparatuses. The radio control apparatus includes a controller configured to execute processes including monitoring the plurality of radio apparatus, selecting, from within the plurality of radio apparatuses, a radio apparatus operating with a large zone cell mode to form a large zone cell being larger than the cell when a monitoring result satisfies a predetermined condition, and switching over the selected radio apparatus to the large zone cell mode.

主权项

1. A radio access system, comprising:
a plurality of radio apparatuses each configured to form a cell; and a radio control apparatus configured to control the plurality of radio apparatuses, the radio control apparatus including: a controller configured to execute processes including: monitoring the plurality of radio apparatuses; selecting, from within the plurality of radio apparatuses, a radio apparatus to be operated with a large zone cell mode to form a large zone cell being larger than the cell when a monitoring result satisfies a predetermined condition; and switching over the selected radio apparatus to the large zone cell mode, wherein the large zone cell is used instead of at least one cell that is not formed by one or more radio apparatuses other than the selected radio apparatus, and the one or more radio apparatuses other than the selected radio apparatus have a failure, wherein the one of the plurality of radio apparatuses which operates with the large zone cell mode is configured to form a large zone cell having an area including a cell of at least a part of the plurality of radio apparatuses; and wherein the radio control apparatus is configured to transmit a control signal to make remaining radio apparatuses other than the one of the plurality of radio apparatuses to be operated with the large zone cell mode switch over to a power save mode to stop forming of a cell covered by the large zone cell.
