Method and system for internetworking with future generation network

A network device comprising:

• a radio communication interface;
• a first communication interface to a first core network;
• a second communication interface to a second core network;
• a memory, wherein the memory stores instructions;
• and
• a processor, wherein the processor executes the instructions to:
• receive, via the radio communication interface, a message from an end device, wherein the message includes capability information of the end device, and wherein the network device is a part of a radio access network, and wherein the network device is a next generation Node B (gNB);
• determine, in response to the receipt of the message, whether to establish a first bearer, which pertains to the end device, with the first core network via the first network interface, or a second bearer, which pertains to the end device, with the second core network via the second network interface based on the capability information, wherein the first bearer is a direct connection with the first core network and the second bearer is a direct connection with the second core network;
• and
• establish, based on a determination, the first bearer or the second bearer.

A non-transitory, computer-readable storage medium storing instructions executable by a processor of a device, which when executed cause the device to:

• receive, via a radio communication interface of the device, a message from an end device, wherein the message includes capability information of the end device, and wherein the device is a part of a radio access network, and wherein the device is a next generation Node B (gNB);
• determine, in response to the receipt of the message, whether to establish a first bearer, which pertains to the end device, with a first core network via a first network interface of the device, or a second bearer, which pertains to the end device, with a second core network via a second network interface of the device based on the capability information, wherein the first bearer is a direct connection with the first core network and the second bearer is a direct connection with the second core network;
• and
• establish, based on a determination, the first bearer or the second bearer.
