Abstract: When mobility management and bearer management of a mobile terminal (111) that is in an idle state and that is associated with a particular core network node identifier (GUMMEI or V-GUMMEI) are transferred from a first core network node (121S) to a second core network node (121T), a base station (112) configures itself to change, from the first core network node (121S) to the second core network node (121T), a forwarding destination of a Non-Access Stratum (NAS) message that is transmitted by the mobile terminal (111) and that is addressed to the particular core network node identifier (GUMMEI or V-GUMMEI). This contributes to, for example, preventing occurrences of signaling involving a mobile terminal when mobility management and bearer management of the mobile terminal in an idle state are transferred between core network nodes.

Abstract: A network function virtualization management and orchestration apparatus includes a VIM(s) and an upper entity(ies) of the VIM(s). The VIM(s) performs resource management and control of an NFVI(s) that provides an execution infrastructure(s) for a VNF(s) implemented and virtualized by software that operates on a virtual machine(s). The upper entity(ies) collects resource information about the NFVI(s) from the VIM(s) and determines a virtual machine allocation destination(s) based on the collected resource information about the NFVI(s). The VIM(s) generates a virtual machine(s) at the determined virtual machine allocation destination(s).

Abstract: There is provided an apparatus comprising: a unit that receives, from a sender, a registration request of an execution condition of a lifecycle of a virtual function under a virtual environment and registers the execution condition of the lifecycle in a storage unit; a unit that secures in advance one or more resources necessary for execution of the lifecycle in the virtual function; a unit that determines whether or not the execution condition of the lifecycle registered in the storage unit is satisfied; a unit that instructs the execution of the lifecycle when the execution condition of the lifecycle is satisfied; and a unit that notifies the lifecycle execution result to the sender of the registration request of the execution condition of the lifecycle.

Abstract: A first network node (121S) is configured to perform mobility management and bearer management of a plurality of mobile terminals (111) having attached to the core network (120). Further, the first network node (121S) is configured to perform a relocation procedure for relocating the mobility management and the bearer management of the plurality of mobile terminals (111) to a second network node (121T) in the core network (120) in accordance with a relocation command from a control node (142) coupled to the core network (120). This contributes, for example, to relocation of mobility management and bearer management of a plurality of mobile terminals between network nodes regardless of the movement of those mobile terminals.
