Abstract: A 5G network includes an access network (AN), a 5G Core (5GC), one or more campus network components each configured to run 5GC software associated to a campus network, and one or more public network components each configured to run 5GC software associated to a public network. The 5GC comprises a central cloud having functionally separated instances, including: a public 5GC instance configured to host the public network realized as a network slice; a private 5GC instance configured to host one or more campus networks, wherein the one or more campus networks are realized as Network Slices; and a data layer instance configured to host Unified Data Repository (UDR) functionality. Unified Data Management (UDM) functions of both 5GC instances are connected to the data layer instance. A Network Slice Selection Function (NSSF) contains the information about network slices present in both 5GC instances.

Abstract: The invention relates to an image recording device, an image reproduction device and a system with such a recording and reproduction device. The recording device comprises an optical axis (1) and a concave mirror (10), whereas through the use of said concave mirror (10) an image of an object (12) can be generated through reflection, the object being located at or projected onto the optical axis (1) near the focal point (11) of the concave mirror (10).
