Radio communication system, radio base station, radio communication terminal, radio communication method, and a non-transitory computer readable medium embodying instructions for controlling a device to implement a control method

摘要

When one base station forms a plurality of cells that use different frequency bands, a handover caused by movement between cells can be successfully performed with a high probability. A radio base station adapted to communicate with a radio communication terminal, comprising: a communication unit which performs a first communication with the radio communication terminal by using a first frequency, wherein the communication unit performs a second communication with the communication terminal by using a second frequency that is different from the first frequency; and a controller which performs a control, of at least one of a first power of the first communication and a second power of the second communication, based on a first power-related quality of the first communication and a second power-related quality of the second communication.

1. A radio base station, adapted to communicate with a radio communication terminal, comprising:
a communication unit which performs a first communication with the radio communication terminal by using a first frequency, wherein the communication unit performs a second communication with the communication terminal by using a second frequency that is different from the first frequency; and a controller which performs a control, of at least one of a first power of the first communication and a second power of the second communication, based on a first power-related quality of the first communication and a second power-related quality of the second communication, wherein: the controller determines whether the first power-related quality is equal to or less than a first predetermined threshold and determines whether the second power-related quality is less than or equal to a second predetermined threshold; when the first power-related quality is equal to or less than the first predetermined threshold or the second power-related quality is equal to or less than a second predetermined threshold, the controller compares a first relative value, which is a difference between the first power-related quality and the first predetermined threshold, and a second relative value, which is a difference between the second power-related quality and the second predetermined quality; when the first relative value is larger than the second relative value, the controller performs control to lower the first power and raise the second power, thereby making the first power-related quality and the second power-related quality substantially equal; and when the first relative value is smaller than the second relative value, the controller performs control to raise the first power and lower the second power, thereby making the first power-related quality and the second power-related quality substantially equal.
