METHOD OF IDENTIFYING ACCESSIBLE NODES AND SYSTEM FOR IMPLEMENTING THE SAME

1 . A method of identifying accessible nodes for a wireless network, the method comprising:

storing a first list of nodes in a first device, wherein the first list comprises a corresponding status of each of the nodes in the first list, and the first device usable in a first technology generation of the wireless network;

updating a second list of nodes in a second device based on the first list of nodes, wherein the second list is free of a status of each of the nodes of the second list, and the second device is usable in a second technology generation of the wireless network different from the first technology generation; and

providing connection information for a node of the second list of nodes to user equipment in response to receiving a connection request from the user equipment.

2 . The method of claim 1 , wherein the first technology generation comprises fifth generation (5G), and the second technology generation comprises fourth generation (4G).

3 . The method of claim 1 , wherein updating the second list comprises removing a node from the second list in response to the first list indicating a status of the node is faulty.

4 . The method of claim 1 , wherein updating the second list comprises adding a node to the second list in response to the first list indicating a status of the node is accessible and the node being absent from the second list.

5 . The method of claim 1 , wherein the first device is separate from the second device.

6 . The method of claim 1 , wherein the first device is integrated with the second device.

7 . The method of claim 1 , wherein the first device comprises a network repository function (NRF), and the second device comprises a domain name system (DNS).

8 . A system for identifying accessible nodes for a wireless network, the system comprising:

a non-transitory computer readable medium configured to store instructions thereon; and

a processor connected to the non-transitory computer readable medium, wherein the processor is configured to execute the instructions for:

instructing the non-transitory computer readable medium to store a first list of nodes in a first device, wherein the first list comprises a corresponding status of each of the nodes in the first list, and the first device usable in a first technology generation of the wireless network;

updating a second list of nodes in a second device based on the first list of nodes, wherein the second list is free of a status of each of the nodes of the second list, and the second device is usable in a second technology generation of the wireless network different from the first technology generation; and

providing connection information for a node of the second list of nodes to user equipment in response to receiving a connection request from the user equipment.

9 . The system of claim 8 , wherein the first technology generation comprises fifth generation (5G), and the second technology generation comprises fourth generation (4G).

10 . The system of claim 8 , wherein the processor is configured to execute the instructions for updating the second list by removing a node from the second list in response to the first list indicating a status of the node is faulty.

11 . The system of claim 8 , wherein the processor is configured to execute the instructions for updating the second list by adding a node to the second list in response to the first list indicating a status of the node is accessible and the node being absent from the second list.

12 . The system of claim 8 , wherein the first device is separate from the second device.

13 . The system of claim 8 , wherein the first device is integrated with the second device.

14 . The system of claim 8 , wherein the first device comprises a network repository function (NRF), and the second device comprises a domain name system (DNS).

15 . A non-transitory computer readable medium configured to store instructions thereon for causing a processor to:

instruct the non-transitory computer readable medium to store a first list of nodes in a first device, wherein the first list comprises a corresponding status of each of the nodes in the first list, and the first device usable in a first technology generation of the wireless network;

update a second list of nodes in a second device based on the first list of nodes, wherein the second list is free of a status of each of the nodes of the second list, and the second device is usable in a second technology generation of the wireless network different from the first technology generation; and

provide connection information for a node of the second list of nodes to user equipment in response to receiving a connection request from the user equipment.

16 . The non-transitory computer readable medium of claim 15 , wherein the first technology generation comprises fifth generation (5G), and the second technology generation comprises fourth generation (4G).

17 . The non-transitory computer readable medium of claim 15 , wherein the instructions are further configured to cause the processor to update the second list by removing a node from the second list in response to the first list indicating a status of the node is faulty.

18 . The non-transitory computer readable medium of claim 15 , wherein the instructions are further configured to cause the processor to update the second list by adding a node to the second list in response to the first list indicating a status of the node is accessible and the node being absent from the second list.

19 . The non-transitory computer readable medium of claim 15 , wherein the first device is separate from the second device.

20 . The non-transitory computer readable medium of claim 15 , wherein the first device is integrated with the second device.
