  • Patent number: 10616854
    Abstract: An SGW-C acquires correlation information in advance and retrieves an SGW-U corresponding to a tracking area of a movement destination of UE with reference to the correlation information. An MME issues a request for connection between the SGW-U retrieved by the SGW-C and an eNB. In this way, since the correlation information in which SGW-Us and tracking areas are correlated with each other is stored, it is possible to appropriately change a tracking area even in a situation in which a control plane and a user plane are separated.

  • Publication number: 20200029273
    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.

  • 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.

  • Patent number: 10390181
    Abstract: A terminal connected to a plurality of user planes retains information on a tracking area where service areas of the plurality of user planes overlap each other as a tracking area identity list. When the terminal moves to the outside of a tracking area described in the tracking area identity list (a tracking area where a plurality of service areas overlap each other), the terminal transmits information on a tracking area after movement and an update request of the tracking area identity list to an MME. The MME creates, as a new tracking area identity list based on the update request, information on a tracking area where service areas in a plurality of user planes overlap in which a tracking area after movement is considered as a service area, and notifies the terminal of the new tracking area identity list for updating a current tracking area identity list.

  • Publication number: 20190230734
    Abstract: In a communication system in which a plurality of bearers are set up between UE and one or more PGWs, a PGW measures an idle time for each bearer and determines whether or not the measured idle time has reached an idle timer threshold value which is determined in advance for each of the plurality of bearers (Step 1). Then, when it is determined that the idle time for one bearer, for example, bearer 2, has reached the idle timer threshold value (Step 2), a PGW2 requests an MME to release bearer 2 via an SGW2 (Steps 3 and 4), and the MME performs a process of releasing bearer 2 in response to the request (Step 5 and the like).

  • Patent number: 10356663
    Abstract: A slice allocating method capable of dynamically changing a service and a slice to be allocated to the service is provided. An OSS/BSS holds allocation service information in which a service to which a slice has been allocated is associated with the slice. Further, a request reception unit of the OSS/BSS receives an SLA-SL which is a requirement of a function. An allocation determination unit determines a slice having an SLA-SL corresponding to a service requirement of the received service. When the service of the slice determined by the allocation determination unit is the same as the service associated with the slice in advance, an allocation request unit reallocates the service to the determined slice.
