The present disclosure aims to provide a core node capable of appropriately allocating a radio resource of a RAN Slice allocated for a specific service to a radio terminal that uses this specific service. A core node () according to the present disclosure includes: a determination unit () configured to determine a radio resource to be allocated in accordance with a service provided for a radio terminal (); and a communication unit () configured to transmit resource identification information indicating the radio resource determined in the determination unit () to a base station () that manages a plurality of radio resources for each RAN Slice associated with a service.

There is provided an audio information providing system that can solve the problem with the audio lag and includes navigation with higher accuracy. The audio information providing system is an audio guidance system including an audio output device that is worn in the ear of a user and an information processing terminal that is communicatively connected to the audio output device. The audio output device includes: an audio output unit configured to output audio to the ear of the user; and a detection unit configured to detect the direction of the head of the user. The information processing terminal includes: a position information acquiring unit configured to acquire a current position of the user; and a generation unit configured to generate audio data which is used for the audio output unit to output audio guidance for a route to a destination to which the user moves from a direction of the destination relative to the direction of the head of the user on the basis of a relationship among position information of the destination, the current position of the user, and information on the direction of the head of the user.

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/OSSdetermines 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.

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.

In an update management system including a plurality of servers executing a communication service, a server not connected to a network in which a new version of an application is operated is generated in parallel with a server in which an old version of the application is operated, and old and new correspondence data between an old version server and a new version server is generated and used to execute switching from the old version server to the new version server in a flow on the network and to execute switching-back to the old version server by referring to the old and new correspondence data at the time of occurrence of fault in a new version.

Update management system and update management method

A node on a core network, in accordance with a connection state of a terminal, releases a transmission path resource which is made unnecessary due to LIPA (Local IP access) or SIPTO (Selected IP traffic offload) connection configuration.

The present invention provides a silicon oxynitride film formation method capable of reducing energy cost, and also provides a substrate equipped with a silicon oxynitride film formed thereby. This method comprises the steps of: casting a film-formable coating composition containing a polysilazane compound on a substrate surface to form a coat; drying the coat to remove excess of the solvent therein; and then irradiating the dried coat with UV light at a temperature lower than 150&#xb0; C.

The present invention can provide a radio communication apparatus comprising an antenna which receives a restriction signal from a radio base station, a reception circuit which decodes the restriction signal received by said antenna, and a control circuit which controls the radio communication apparatus, in which the control circuit can be adapted to select appropriately a speech outgoing/incoming scheme for performing communication with the radio base station on the basis of the restriction signal from the radio base station. As the speech outgoing/incoming scheme, a domain scheme or a speech communication scheme is used. In addition, the present invention further provides a communication network control system using the radio communication apparatus, and a communication network control method.
