Title:

A maintenance management device, a radio communications system, a use architecture deciding method, and a computer program

Document Type and Number:

Japanese Patent JP6207440

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To contribute to performing dual connectivity by using a plurality of base station devices each supporting a different architecture.SOLUTION: The base station device for relaying a communication link established between a communication device and a terminal device includes: a communication section 12 that transmits support architecture information of own base station device to a maintenance management device and receives from the maintenance management device support architecture information of another base station device or used architecture information representing an architecture used between own base station device and the other base station device among a plurality of architectures that establishes another communication link with the terminal device through the other base station device while leaving part of communication link at a certain base station device when establishing the communication link; and a storage section 14 that stores support architecture information or used architecture information received from the maintenance management device.
