The embodiments of the disclosure relates to a device location manager for a communication system, the device location manager comprising: a southbound interface configured to receive a physical location information of a mobile device from an infrastructure manager of the communication system, a location processor configured to map between the physical location information and a logical location information, and a northbound interface configured to send and/or receive the logical location information to and/or from at least two network slices of the communication system.

Method and system for device location management

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. A management system included in a mobile communication system is configured to include an NFVI which is virtualization resources including a physical server in which a VNF to execute a communication process is generated and includes a VNFM for managing the VNF, a VIM for managing the virtualization resources of the NFVI, and an orchestrator for managing all the virtualization resources of the NFVI, wherein the orchestrator includes a virtual server generation request section configured to input detailed information for implementing the VNF retained by the VNFM, rewrite the input detailed information according to a virtualization resource management scheme by the VIM, and request the VIM to generate the VNF.

Management system, overall management node, and management method for managing virtualization resources in a mobile communication network

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 () included in a mobile communication system () configured to include an NFVI () which is virtualization resources including a physical server generated by a VNF () to execute a communication process, and the system includes a VNFM () for managing the VNF (), a VIM () for managing the virtualization resources of the NFVI (), an orchestrator () for managing all the virtualization resources of the NFVI (), wherein the VNFM () includes a retention section () configured to retain detailed information for implementing the VNF () and a virtual server generation request section () configured to request the VIM () to generate the VNF () using the detailed information.

Management system, virtual communication-function management node, and management method for managing virtualization resources in a mobile communication network

A method for implementing an entity of a network by virtualizing said network entity and implementing it on one or more servers each acting as an execution unit for executing thereon one or more applications running and/or one or more virtual machines running on said execution unit, each of said application programs or virtual machines running on a server and implementing at least a part of the functionality of said network entity being called a virtual network function VNF module, wherein a plurality of said VNF modules together implement said network entity to thereby form a virtual network function VNF, said method comprising the steps of: obtaining m key performance indicators (KPI) specifying the required overall performance of the VNF, obtaining n performance characteristics for available types of execution units, determining one or more possible deployment plans based on the obtained m KPI and n performance characteristics, each deployment plan specifying the number and types of execution units, such that the joint performance of VNF modules running on these execution units achieves the required overall performance of the VNF.
