Core router for a multi-purpose cellular network with 5g proxy functionalities

One or more non-transitory computer-readable media comprising computer-readable instructions, which when executed by one or more processors of a management system of a multi-purpose cellular network, cause the management system to:

• receive a connection request for an endpoint to connect to the multi-purpose cellular network, the endpoint being associated with at least one external network operator, wherein a core network of the external network operator associated with the endpoint is one of a fourth generation (4G) core network or a fifth generation (5G) core network, the management system including a first interface configured to communicatively couple with at least one fifth-generation (5G) base station of the multi-purpose cellular network, a second interface configured to communicatively couple with at least one fourth-generation (4G) base station of the at least one external network operator, and a third interface configured to communicatively couple with the at least one external network operator;
• establish a network connection for the endpoint to operate on the multi-purpose cellular network based on a service level agreement between a corresponding external network operator of the endpoint and the multi-purpose cellular network obtained via the third interface;
• and
• manage the network connection for the endpoint, wherein managing the network connection includes at least routing network traffic for the endpoint to:
• a 4G core network of the corresponding external network operator via the first interface for user traffic and via the second interface for control signals, if the core network of the corresponding external network is a 4G core network;
• or
• a 5G core network of the corresponding external network operator via the first interface, if the core network of the corresponding external network is a 5G core network.
