Estimating the term…
In a communication system (1), when there is no access destination corresponding to a service type to be used by a piece of UE (50) in one of cellular communication and non-cellular communication, a retrieval unit (13) of a DB server (10) selects an access destination by referring to correspondence information in the other of the cellular communication and the non-cellular communication. Thus, when there is no access destination corresponding to the service type to be used by the UE (50) in one of the cellular communication and the non-cellular communication, the access destination corresponding to the service type is selected in the other of the cellular communication and the non-cellular communication. Therefore, it is possible to select an access destination suitable for the service type from both the cellular communication and the non-cellular communication.
A gateway selection method for selecting a gateway device that constitutes a slice satisfying requirements of a communication service to be used by a terminal, the gateway selection method being executed by a communication system including the terminal capable of using a communication service and a plurality of gateway devices, the communication system being a system where a plurality of slices are generated, each slice being a virtual network or a service network logically generated on a network infrastructure, the gateway selection method comprising:
A communication system including a terminal capable of using a communication service and a plurality of gateway devices that perform communication for using the communication service, the communication system being a system where a plurality of slices are generated, each slice being a virtual network or a service network logically generated on a network infrastructure, the communication system comprising:
