  • Gateway selection method and communication system
    Patent number: 10772037
    Abstract: 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.

  • GATEWAY SELECTION METHOD AND COMMUNICATION SYSTEM
    Publication number: 20200022074
    Abstract: In a communication system (1), a communication service to be used by a piece of UE (30) that has requested access is identified, and an ePDG (40) or a PGW (60) is dynamically selected on the basis of the identified communication service. Thus, it is possible to appropriately provide a communication service requested by a user. Therefore, it is possible to dynamically select the ePDG (40) or the PGW (60) according to requirements of the service requested by the UE (30) (for example, requirements of a network for executing a service). Accordingly, it is possible to provide a suitable communication service to a user of the UE (30) who uses a plurality of services.
