RADIO RELAY DEVICE, VIRTUAL MACHINE GENERATION SERVER, RADIO RELAY METHOD, AND VIRTUAL MACHINE GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To solve the conventional problem that introduction of a control device corresponding to a remote unit in each hop has been necessary when connecting to a core network of another communication carrier.

SOLUTION: A radio relay device includes: an initiation request transmission unit for transmitting an initiation request of a virtual machine of each control device required for a service of a radio system A, to a virtual machine generation server for generating the virtual machine; in response to the transmission of the initiation request, an initiation completion report reception unit for receiving an initiation completion report which is a report of initiation completion of the virtual machine from the virtual machine generation server and includes communication destination information indicative of a communication destination to communicate with the virtual machine; and a set information transmission unit for transmitting set information including the communication destination information included in one or more initiation completion reports, to other virtual machines than the virtual machine corresponding to the communication destination information. By this, equipment investment cost can be remarkably reduced when connecting to the core network of the other communication carrier.
