Abstract: A problem to be solved is to control a network slice from a core network. A method to be executed by an information processing apparatus in a cloud-based computing environment includes the steps of: receiving, from a mobility management device, a congestion notification including a slice identifier for a congested slice; transmitting, to a slice allocation device, a setting request for setting a subslice to the slice corresponding to the slice identifier, upon reception of the congestion notification; and transmitting, when a subslice identifier associated with the slice identifier is set in the slice allocation device and the subslice identifier is added in the mobility management device, an instruction to establish communication using the subslice corresponding to the subslice identifier and the slice corresponding to the slice identifier to the mobility management device.

Abstract: Seamless communication between mobile communication networks complying with different standards is enabled. A method including a first step group executed by a processor of an information processing apparatus, the first step group including the steps of: acquiring a position registration request from a user terminal; judging whether an identification number of a first communication carrier included in the position registration request is different from an identification number of a communication carrier associated with the user terminal, which is registered with a subscriber database; and instructing a mobility management node to set a first network of the first communication carrier when the identification number of the first communication carrier is different from the identification number of the communication carrier registered with the subscriber database.

Abstract: A system for controlling handover is disclosed that includes a mobile terminal that enables communications with multiple wireless systems having wireless access stations, and a handover-controlling apparatus that executes control of handover for the mobile terminal, which travels among multiple types of wireless systems. The mobile terminal includes a destination wireless system determining unit that receives downlink signals from the corresponding wireless access stations so as to determine which wireless system accommodates a destination wireless access station based on reception quality of downlink signals. The mobile terminal also includes a destination wireless system reporting unit that sends information indicating the determined wireless system to the handover-controlling apparatus.

Abstract: A communication control unit receives destination terminal identification information and communication software from a source communication terminal. The communication control unit installs software. Address information of another communication control unit is acquired from an externally located apparatus. The another communication control unit can be connected to a destination communication terminal corresponding to the destination terminal identification information. The destination terminal identification information and software identification information uniquely identifying the installed software is transmitted to an address of the another communication control unit included in the address information. Software identification data is transmitted to the another communication control unit. Software corresponding to the software identification data is received and installed to control a network connection of the another communication control unit.

Abstract: A network control system, which controls connections between a mobile terminal and multiple types of wireless systems accommodated in a network, includes a prescribed node provided on the network. The node comprises signal transmitting/receiving means that transmits and receives a control signal defined by each of the wireless systems, protocol converting means that converts the control signal to a common protocol independent of each of the wireless systems, and entity communication controlling means that communicates with multiple functional entities provided on the network, using the common protocol, to implement network control.
