Base station control module, wireless base station, base station control device, and base station control method

摘要

A wireless base station that solves a problem in which both the suppression of a power consumption of a wireless base station and the reduction of the period that a mobile terminal takes to identify a cell cannot be satisfied at a time is provided. Determination section 101 determines whether or not a mobile terminal is present in a cell that wireless base station 10a manages. If determination section 101 determines that a mobile terminal is present, control section 102 sets wireless base station 10a for a first transmission repetition as a transmission repetition of a pilot signal; if determination section 101 determines that no mobile terminal is present, control section 102 sets wireless base station 10a for a second transmission repetition lower than the first transmission repetition as a transmission repetition of the pilot signal.

主权项

1. A base station control module that controls a wireless base station that transmits its own cell pilot signal, comprising:
a determination section that periodically determines whether or not a mobile terminal is present in an own cell that said wireless base station manages; a control section that sets said wireless base station for a first transmission repetition as a transmission repetition at which said own cell pilot signal is transmitted by said wireless base station if said determination section determines that said mobile terminal is present and that sets said wireless base station for a second transmission repetition that is lower than said first transmission repetition as said transmission repetition if said determination section determines that said mobile terminal is not present; and a communication section that receives from a mobile terminal that is present in said own cell a first measurement report that denotes that a received signal strength of an adjacent pilot signal that an adjacent wireless base station that adjoins said wireless base station transmits becomes equal to or greater than a predetermined first threshold and a second measurement report that denotes that the received signal strength of said adjacent pilot signal becomes equal to or greater than a second threshold that is lower than said first threshold, wherein said control section performs a handover of said mobile terminal to a relevant adjacent wireless base station if said communication section receives said first measurement report and transmits to said adjacent wireless base station a repetition change request that causes a repetition at which said adjacent pilot signal is transmitted to be set for said first transmission repetition if said communication section receives said second measurement report.
