Patent number: 10356663Abstract: 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.Type: GrantFiled: September 15, 2016Date of Patent: July 16, 2019Assignee: NTT DOCOMO, INC.Inventors: Takuya Shimojou, Motoshi Tamura, Masayoshi Shimizu, Ashiq Khan, Shigeru Iwashina

Patent number: 10284495Abstract: A slice management system and a slice management method that can dynamically adjust the amount of resources when the amount of resources is insufficient to create a slice. A storing unit of a NFVO stores slice utilization status information. In a BSS/OSS, an allocation determination unit determines to create a new slice or extend an existing slice, and when resources for creation of a new slice or extension of an existing slice are insufficient, a resource change determination unit determines a slice for reduction based on the slice utilization status information. A resource request unit of the NFVO reduces resources of the determined slice.Type: GrantFiled: March 11, 2016Date of Patent: May 7, 2019Assignee: NTT DOCOMO, INC.Inventors: Takuya Shimojou, Yusuke Takano, Motoshi Tamura, Ashiq Khan

Patent number: 10285063Abstract: A service allocation determination device and service allocation determination method that can allocate a service to a slice without wasteful use of resources. In a BSS/OSS, a service request receiving unit receives service requirements and information indicating functions for implementing a service. An allocation determination unit, using the service requirements and slice information, determines whether to allocate the service to an existing slice or to a new slice. An allocation request unit makes a request to allocate the service to the slice determined by the allocation determination unit. In this case, because the BSS/OSS 10 determines whether to allocate the service to an existing slice or to a new slice based on the service requirements and the attribute of the existing slice, the service can be allocated to a slice without wasteful use of resources.Type: GrantFiled: March 11, 2016Date of Patent: May 7, 2019Assignee: NTT DOCOMO, INC.Inventors: Takuya Shimojou, Motoshi Tamura, Yusuke Takano, Ashiq Khan, Shigeru Iwashina

Publication number: 20190059036Abstract: A slice management system is a system managing a slice that is a virtual network generated on a network infrastructure and includes a DNS storing slice information relating to a slice to which a UE can be connected for each area and determines whether or not the UE can, in a moving destination area that is a destination of movement of the UE between areas, be connected to a slice to which the UE was connected in a moving source area by referring to the DNS. In a case in which it is determined that the connection cannot be made, the slice management system generates the slice in the moving destination area such that the UE can be connected to the slice in the moving destination area.Type: ApplicationFiled: March 29, 2017Publication date: February 21, 2019Applicant: NTT DOCOMO, INC.Inventors: Takuya SHIMOJOU, Tomoki SHIBAHARA, Atsushi MINOKUCHI, Masayoshi SHIMIZU, Ashiq KHAN, Kazuaki OBANA, Srisakul THAKOLSRI, Malla Reddy SAMA, Wolfgang KIESS, Joan TRIAY MARQUES
