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.

Method for controlling network slice, information processing apparatus, and system

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.
