Classification: CPC H | IPC H

Claim 3:
4. A communication system comprising:
a slice selection device that selects a slice serving as a virtual network logically generated in a network infrastructure; and
a plurality of processing servers that execute processing related to a terminal while each processing server of the plurality of processing servers is associated with one or more slices,
wherein the slice selection device includes
a memory that retains slice correspondence information including information in which the slice, a processing server corresponding to the slice, and a service to be used by a terminal are associated with one another,
a slice selection processor that selects a slice corresponding to a service related to a request for use from the terminal and a target processing server corresponding to the slice based on the slice correspondence information, and
a transmitter that notifies the processing server of selection result information including information related to the slice and the target processing server which have been selected,

wherein the processing server includes
a transceiver that receives a request for use of a service from the terminal and transfers the request for use to the slice selection device, and
a server processor that determines whether or not the processing server is the target processing server based on the information related to the target processing server included in the selection result information notified from the slice selection device,
wherein, in response to a determination that the one processing server is the target processing server selected by the slice selection device, the one processing server performs processing for a service related to the request for use, and
wherein, in response to a determination that the one processing server is not the target processing server selected by the slice selection device, the one processing server transfers a request for processing for a service related to the request for use, to the target processing server, and

wherein the slice selection processor or the server processor sends a query to a user data manager which manages information related to a terminal user regarding whether or not the terminal is capable of using the selected slice.
