A software defined network (SDN) can add network repository functions (NRF) into a configurations database to enable NF discovery. The SDN can subscribe to NRF notifications to receive new cloud native functions (CNF), registrations, or any other update to the CNF status in 5G system. In addition to listening to NRF notifications, the SDN can implement CNF pooling processes to periodically retrieve CNF from an NRF repository and stay in sync with 5G systems. Thus, a deep service path discovery can be developed from network service configurations and container call flows to enable an accurate alarm correlation and troubleshooting for the operations. This service path deep discovery can be designed and implemented as a standalone system or in an SDN framework with integration of a container management framework such as K8 kubernetes.

The present invention relates to an offline-operable wireless network system and. the method for operating the same. When a wireless base station is not connected to the evolved packet core (EPC) server, the wireless base station will emulate the EPC server. Thereby, the electronic device connected with the wireless base station can be connected to the emulated EPC server, so that the wireless network functions still can be applied in the offline state and a wireless local area network can be further built.

The embodiments herein relate to a method performed by a SMF (110) for handling a UEs (101) access to a DN (130) in a 5G communications system. The SMF (110) obtains at least one anycast address supported at a DN/I (130/I) which is accessible by the UE (101) from its location. The SMF (110) sends instructions to a UPF/c (105/c) to report usage of the at least one anycast address. The SMF (110) receives, from the UPF/c (105/c), information that usage of the anycast address has been detected. When usage of the anycast address has been detected, the SMF (110) determines that future usage of the anycast address should be routed to the DN/I (130/I) via the UPF/I (105/I).

A routing selection method, apparatus, device and system and a storage medium are provided. The method includes receiving a route reassignment message sent by a serving core network device. The route reassignment message includes at least one of at least one of identification information or address information of an initial core network device; at least one of identification information or address information of the serving core network device; a context identifier assigned for a served object in at least one of the initial core network device, the access network device or the serving core network device; network slice information supported by the served object; or operator information supported by the served object.

A communication control apparatus includes a processor configured to acquire communication information representing connection information of a first network slice, which is assigned as a connection destination of a terminal used by a user, among wireless communication lines respectively provided by communications carriers, from a control apparatus that controls the first network slice; and perform control to switch a network slice such that a second network slice different from the first network slice is assigned to the terminal, in a case where a deterioration of a communication quality of the first network slice is notified by using the communication information.

Enabling routing of traffic to/from a roaming host node roaming from a subnet of a home network to a visited network, the host node assigned an IP address in the home network, comprising configuring, in a router of the visited network, a subnet by assigning an IP address range to the subnet, which is in the same IP address range of the subnet of the home network; configuring a tunnel between a router of the home network and the router; configuring a static route to route traffic from a host node destined to the roaming host node; and configuring the router by applying a routing policy enabling the roaming host node to reply to received traffic from said host node received from a first interface and route traffic from the roaming host node through a network interconnecting the router of the visited network and the router of the home network.

A method of operating a first infrastructure equipment is provided. The method comprises communicating, signals representing data with a second infrastructure equipment over a first communications path optionally via one or more others of the infrastructure equipment acting as relay nodes, detecting that one or more of the beams used for communicating signals with a third infrastructure equipment satisfy a beam failure condition, determining, in response to detecting that the one or more of the beams satisfy the beam failure condition, that a beam failure notification is to be transmitted, the beam failure notification indicating that the one or more of the beams satisfy the beam failure condition, and transmitting the beam failure notification.

A single platform for controller functionality for each of security, monitoring and automation, as well as providing a capacity to function as a bidirectional Internet gateway, is provided. Embodiments of the present invention provide such functionality by virtue of a configurable architecture that enables a user to adapt the system for the user's specific needs. Embodiments of the present invention further provide such functionality by providing for installation of removable, modular communication adapters for communication with a variety of devices external to the security, monitoring and automation controller.
