摘要:
In an update management system including a plurality of servers executing a communication service, a server (VNF2) not connected to a network in which a new version of an application is operated is generated in parallel with a server (VNFM1) in which an old version of the application is operated, and old and new correspondence data between an old version server and a new version server is generated and used to execute switching from the old version server (VNF1) to the new version server (VNF2) in a flow on the network and to execute switching-back to the old version server (VNF1) by referring to the old and new correspondence data at the time of occurrence of fault in a new version.

An object of the invention is to provide a communication service with high utilization efficiency. A mobile communication network distribution system includes: an acquisition unit that acquires condition information; a determination unit that determines a degenerate mobile communication network which provides a function satisfying a functional requirement based on the condition information acquired by the acquisition unit among a plurality of mobile communication networks to be a connection destination mobile communication network which is a connection destination of the UE; and a distribution unit that distributes the connection destination of the mobile communication terminal to the connection destination mobile communication network determined by the determination unit.
摘要:
A virtual server for executing a communication process is implemented on virtualization resources without being inefficient even when different virtualization resource management schemes are included. There is provided a management system (10) included in a mobile communication system (1) configured to include an NFVI (60) which is virtualization resources including a physical server in which a VNF (70) to execute a communication process is generated and includes a VNFM (30) for managing the VNF (70), a VIM (40) for managing the virtualization resources of the NFVI (60), and an orchestrator (20) for managing all the virtualization resources of the NFVI (60), wherein the orchestrator (20) includes a virtual server generation request section (23) configured to input detailed information for implementing the VNF (70) retained by the VNFM (30), rewrite the input detailed information according to a virtualization resource management scheme by the VIM (40), and request the VIM (40) to generate the VNF (70).

An object is to seamlessly migrate a virtual machine with less influence on services in an NFV environment. A VIM 16 is a VIM 16 for managing each virtualized resource that is included in an NFV environment 1 including virtualized resources including a physical machine in which a virtual machine having a VNF 12 being a virtualized communication function is implemented, and the VIM 16 includes a switching unit 23 for switching a network flow from a virtual machine of a migration source to a virtual machine of a migration destination, or switching a system between an Active (ACT) system virtual machine of a migration source and a Standby (SBY) system virtual machine of a migration destination.
摘要:
Redundancy of a call-processing node having excellent reliability, economic efficiency and flexibility can be realized. A mobile communication system 1 includes a plurality of call-processing servers 20, a call processing management database 10 that holds data necessary for call processing, and a network manager 40. The network manager 40 comprises a node state recognition unit 41 that recognizes states of the call-processing servers 20, and a control unit 42 that determines and controls the call-processing node that processes a call processing request based on the states. The call-processing server 20 comprises a call processing request accepting unit 21 that accepts a call processing request, an acquisition unit 22 that acquires information of a mobile communication terminal 50 related to the call processing request from the call processing management database 10, a call processing unit 23 that performs call processing using the acquired information; and a call processing result storage unit 24 that stores information of a result of the call processing in the call processing management database 10.
摘要:
Leakage of detailed information for implementing a virtual server to execute a communication process on virtualization resources is prevented. There is provided a management system (10) included in a mobile communication system (1) configured to include an NFVI (60) which is virtualization resources including a physical server generated by a VNF (70) to execute a communication process, and the system includes a VNFM (30) for managing the VNF (70), a VIM (40) for managing the virtualization resources of the NFVI (60), an orchestrator (20) for managing all the virtualization resources of the NFVI (60), wherein the VNFM (30) includes a retention section (31) configured to retain detailed information for implementing the VNF (70) and a virtual server generation request section (32) configured to request the VIM (40) to generate the VNF (70) using the detailed information.
