Broadband network gateway (BNG) as dynamic host configuration protocol (DHCP) server

1. A method, comprising:

receiving, by a broadband network gateway (BNG) and from a customer premises equipment, a dynamic host configuration protocol (DHCP) discover request,

wherein the BNG is connected to the customer premises equipment and a fixed mobile interworking function (FMIF);

communicating with, based on the DHCP discover request, the FMIF;

providing, by the BNG, to the customer premises equipment, and based on communicating with the FMIF, a DHCP offer that offers utilization of the BNG as a DHCP server;

receiving, by the BNG, from the customer premises equipment, and based on providing the DHCP offer, a DHCP request to request utilization of the BNG as the DHCP server; and

providing, by the BNG, to the customer premises equipment, and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server.

2. The method of claim 1 , wherein the customer premises equipment is a fixed network cable residential gateway.

3. The method of claim 1 , wherein the DHCP acknowledgment indicates that the customer premises equipment is assigned an Internet protocol version 4 (IPv4) address.

4. The method of claim 1 , wherein the DHCP acknowledgment indicates that the customer premises equipment is assigned an Internet protocol version 6 (IPv6) address.

5. The method of claim 1 , wherein communicating with the FMIF allows the FMIF to cause:

a context to be established for the customer premises equipment;

a protocol data unit (PDU) session to be established for the customer premises equipment; and

a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.

6. The method of claim 1 , wherein communicating with the FMIF comprises:

providing, to the FMIF, a login request; and

receiving, from the FMIF and based on providing the login request, a login success response,

wherein receiving the login success response allows the BNG to provide the DHCP offer to the customer premises equipment.

7. The method of claim 1 , further comprising:

receiving, based on providing the DHCP acknowledgment, an address resolution protocol (ARP) request that requests an address of the BNG;

providing, to the customer premises equipment, and based on the ARP request, an ARP response that includes the address of the BNG; and

mapping, based on providing the ARP response, the address of the BNG to a protocol data unit (PDU) session identifier of a PDU session established for the customer premises equipment.

8. The method of claim 7 , further comprising:

enabling data packets to be provided from the customer premises equipment to a data network, via a general packet radio service (GPRS) tunneling protocol (GTP) tunnel, based on mapping the address of the BNG to the PDU session identifier.

9. A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

one or more instructions that, when executed by one or more processors of a broadband network gateway (BNG), cause the BNG to:

receive, from a customer premises equipment, a dynamic host configuration protocol (DHCP) discover request;

provide, to the customer premises equipment, a DHCP offer that offers utilization of the BNG as a DHCP server;

receive, from the customer premises equipment and based on providing the DHCP offer, a DHCP request to request utilization of the BNG as the DHCP server; and

provide, to the customer premises equipment and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server.

10. The non-transitory computer-readable medium of claim 9 , wherein the customer premises equipment is a fixed network cable residential gateway.

11. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:

assign, based on the DHCP request, the customer premises equipment an Internet protocol version 4 (IPv4) address.

12. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:

assign, based on the DHCP request, the customer premises equipment an Internet protocol version 6 (IPv6) address.

13. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:

communicate, based on receiving the DHCP discover request, with a fixed mobile interworking function (FMIF) to allow the FMIF to cause at least one of:

a context to be established for the customer premises equipment;

a protocol data unit (PDU) session to be established for the customer premises equipment; or

a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.

14. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:

provide, to a fixed mobile interworking function (FMIF) and based on the DHCP discover request, a login request; and

receive, from the FMIF and based on providing the login request, a login success response,

wherein receiving the login success response allows the BNG to provide the DHCP offer to the customer premises equipment.

15. The non-transitory computer-readable medium of claim 9 , wherein the one or more instructions further cause the BNG to:

receive, based on providing the DHCP acknowledgment, an address resolution protocol (ARP) request that requests an address of the BNG;

provide, to the customer premises equipment, and based on the ARP request, an ARP response that includes the address of the BNG; and

map, based on providing the ARP response, the address of the BNG to a protocol data unit (PDU) session identifier of a PDU session established for the customer premises equipment.

16. The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions further cause the BNG to:

enable data packets to be provided from the customer premises equipment to a data network based on mapping the address of the BNG to the PDU session identifier.

17. A broadband network gateway (BNG), comprising:

one or more memories; and

one or more processors to:

provide, to a customer premises equipment, a dynamic host configuration protocol (DHCP) offer that offers utilization of the BNG as a DHCP server;

receive, from the customer premises equipment, and based on providing the DHCP offer, a DHCP request to request utilization of the BNG as the DHCP server; and

provide, to the customer premises equipment, and based on the DHCP request, a DHCP acknowledgment that acknowledges utilization of the BNG as the DHCP server.

18. The BNG of claim 17 , wherein the one or more processors are further to:

communicate with a fixed mobile interworking function (FMIF) to allow the FMIF to cause at least one of:

a context to be established for the customer premises equipment;

a protocol data unit (PDU) session to be established for the customer premises equipment; or

a general packet radio service (GPRS) tunneling protocol (GTP) tunnel to be established for the customer premises equipment.

19. The BNG of claim 17 , wherein the one or more processors are further to:

receive, based on providing the DHCP acknowledgment, an address resolution protocol (ARP) request that requests an address of the BNG;

provide, to the customer premises equipment, and based on the ARP request, an ARP response that includes the address of the BNG; and

map, based on providing the ARP response, the address of the BNG to a protocol data unit (PDU) session identifier of a PDU session established for the customer premises equipment.

20. The BNG of claim 19 , wherein the one or more processors are further to:

enable data packets to be provided from the customer premises equipment to a data network based on mapping the address of the BNG to the PDU session identifier.
