A communication system for providing communication within a 5G communication network, the communication system, comprising: at least one communication terminal comprising a global identity, wherein the communication terminal is a 5G device, wherein the at least one communication terminal comprises a terminal-side conversion table for translating the global identity into a temporary identity, wherein the communication terminal is identified by its temporary identity, wherein the temporary identity is an IMSI or an SUPI, wherein the terminal-side conversion table is part of a central representation that is hold in a central location of the cellular network; a network device configured to connect the at least one communication terminal at least temporarily with the cellular network, wherein the network device and the at least one communication terminal form an extended communication terminal for processing applications of the at least one communication terminal and to assign a global identity, which is a global IMSI or a global SUPI, to the extended communication terminal, wherein the network device is a 5G EDGE, wherein the network device is configured to authenticate the at least one communication terminal based on the terminal's temporary identity, wherein the connection between the extended communication terminal and the 5G core network is identified and addressed based on the global IMSI or the global SUPI assigned to the extended terminal and a device ID of the extended terminal, wherein the network device is configured to derive the global identity from a network-side conversion table that shows a conversion of global identities in the cellular network to temporary identities of extended communication terminals according to a conversion scheme that enables unique utilization of temporary identities within the cellular network, wherein the network-side conversion table is part of the central representation in the cellular network that allows identity management in the cellular network ensuring that the at least one communication terminal appears for external parties with different identities. at least one communication terminal comprising a global identity, wherein the communication terminal is a 5G device, wherein the at least one communication terminal comprises a terminal-side conversion table for translating the global identity into a temporary identity, wherein the communication terminal is identified by its temporary identity, wherein the temporary identity is an IMSI or an SUPI, wherein the terminal-side conversion table is part of a central representation that is hold in a central location of the cellular network; a network device configured to connect the at least one communication terminal at least temporarily with the cellular network, wherein the network device and the at least one communication terminal form an extended communication terminal for processing applications of the at least one communication terminal and to assign a global identity, which is a global IMSI or a global SUPI, to the extended communication terminal, wherein the network device is a 5G EDGE, wherein the network device is configured to authenticate the at least one communication terminal based on the terminal's temporary identity, wherein the connection between the extended communication terminal and the 5G core network is identified and addressed based on the global IMSI or the global SUPI assigned to the extended terminal and a device ID of the extended terminal, wherein the network device is configured to derive the global identity from a network-side conversion table that shows a conversion of global identities in the cellular network to temporary identities of extended communication terminals according to a conversion scheme that enables unique utilization of temporary identities within the cellular network, wherein the network-side conversion table is part of the central representation in the cellular network that allows identity management in the cellular network ensuring that the at least one communication terminal appears for external parties with different identities.
