  • Publication number: 20190037521
    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: 20190014504
    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.

  • Publication number: 20180367953
    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: 20180041931
    Abstract: A correspondence information storage 32 acquires correspondence information in which an eNB 20, an SGW-C 60, and an SGW-U 70 are associated with each other in advance, and a connection controller 31 receives a handover request from the eNB 20 and identifies a target eNB 20 and a source eNB 20. A connection changer 33 identifies the SGW-C 60 and the SGW-U 70 associated with the target eNB 20 and identifies the SGW-C 60 and the SGW-U 70 associated with the source eNB 20, with reference to the correspondence information. The connection changer 33 determines whether or not the SGW-C 60 and the SGW-U 70 are to be changed on the basis of the identified result, and controls change requests for at least one of the SGW-C 60 and the SGW-U 70 on the basis of a result of the determination.

  • Patent number: 9672856
    Abstract: A magnetic media having a lateral exchange control layer formed on a magnetic oxide layer of a magnetic recording layer. A cap layer is formed over the lateral exchange control layer. The lateral exchange control layer can be an alloy comprising Co and one or more of W, Ru, Hf, Ta, Nb and Fe. The lateral exchange control layer has the highest magnetic saturation moment among all the recording layers, and increases spacing between magnetic grains (e.g. increased non-magnetic boundary width), thereby reducing lateral exchange sigma. The presence of lateral exchange control increases signal to noise ratio and reduces bit error rate and increases areal density.
