摘要： 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.

摘要： A mobile communication system includes an OpenFlow network and CSCFs. A first CSCF comprises a terminal information assigning unit that assigns information of an incoming terminal of a destination of a signal accommodated in a second CSCF to a header part of a signal destined for the second CSCF. The OpenFlow network comprises a storage unit that stores a correspondence relationship between the incoming terminal and a device accommodating the incoming terminal, a terminal information acquisition unit that acquires information of the incoming terminal from the header part of the signal, a transmission destination identification unit that identifies the device that is a transmission destination from the information, and an open flow transmission unit that transmits a signal to the identified device.

摘要： An object is to provide a slice management system capable of assigning slices to a plurality of business operators. In a parent SMF 100, a slice management table 103 can manage resources of a slice managed by a child SMF 100a or the like, and a communication unit 101 can notify the child SMF 100a or the like of the resources. The child SMF 100a or the like receives the resources and stores the resources in the slice management table 106. Therefore, the child SMF 100a or the like can manage the resources of the slice managed by the child SMF 100a or the like, and the child SMF 100a can independently enable the management of the resources.

摘要： 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).

摘要： 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.
