A method to enable secure data communication between a first network of a first network provider and a second network of a second network provider includes: establishing a handover process from a 5G communication environment of a first network to a 4G communication environment of a second network; directing control plane traffic of the data transmission from a security edge protection proxy (SEPP) of the first network to a SEPP of the second network; directing user plane traffic of the data transmission to an access link to the 4G communication environment of the second network and through a GTP-firewall; and providing decrypted control plane traffic to the GTP-firewall, wherein the GTP-firewall performs security measures based on information extracted from the control plane traffic.

Techniques to enable secure data communication between a first network and a second network that comprise at least in part a different communication environment

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.

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 () and a concave mirror (), whereas through the use of said concave mirror () an image of an object () can be generated through reflection, the object being located at or projected onto the optical axis () near the focal point () of the concave mirror (). A flat light scanner surface () is disposed between the concave mirror () and the object () such that the light beams () reflected by the concave mirror () generate a two-dimensional projection of the object () on the light scanner surface (), whereas the light scanner surface () comprises light receptors () through which the incident light beams () of the two-dimensional projection can be captured in relation to their frequency and/or phase and/or magnitude, whereas means are provided through which the captured two-dimensional projection can be encoded in an electronic file. Furthermore, the reproduction device comprises a flat projection surface () for displaying a two-dimensional graphic, the projection surface being disposed between a concave mirror () and a three-dimensional projection () to be generated of an object (). Means are provided for decoding the electronic file and for causing the graphic to be displayed on the projection surface () according to the frequency and/or phase and/or magnitude information about light beams encoded in the electronic file. Through the use of said mirror () a three-dimensional projection () of the object () can be generated through reflection of the light beams () emitted from the projection surface ().
