System and method for delivery of end device policies during registration procedure

1. A method comprising:

receiving, by a network device of a core network from an end device, a first message that includes an initial registration request and an end device policy request that includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message, and wherein the end device is not registered with the network device;

executing, by the network device in response to receiving the first message, a registration procedure and a policy control procedure;

determining, by the network device, whether the registration procedure and the policy control procedure are completed;

generating, by the network device, when the registration procedure and the policy control procedure are completed, a second message that includes a registration response and an end device policy, wherein the first message is received as a non-access stratum message and the second message is transmitted as another non-access stratum message; and

transmitting, by the network device to the end device, the second message.

2. The method of claim 1 , wherein the second message includes a registration accept message that includes an information element, wherein the information element includes the end device policy.

3. The method of claim 1 , further comprising:

storing, by the network device, the end device policy only when the registration procedure is not completed and the policy control procedure is completed.

4. The method of claim 1 , further comprising:

transmitting, by the network device, a registration request to a unified data management device.

5. The method of claim 1 , wherein determining whether the registration procedure and the policy control procedure are completed further comprises:

determining, by the network device, whether a registration response is received from a unified data management device or a home subscriber server; and

determining, by the network device in response to determining that the registration response is received, that the registration procedure is completed.

6. The method of claim 1 , wherein determining whether the registration procedure and the policy control procedure are completed further comprises:

determining, by the network device, whether a policy control create response is received from a policy control function device or a policy charging and rules function; and

determining, by the network device in response to determining that the policy control create response is received, that the policy control procedure is completed.

7. The method of claim 1 , wherein the end device policy includes at least one of a route selection policy or an access discovery and selection policy.

8. The method of claim 1 , wherein the network device is a mobility management entity device or an access and management function device, and the core network includes an evolved packet core network or a next generation core network.

9. A network device comprising:

a communication interface;

a memory, wherein the memory stores instructions; and

a processor, wherein the processor executes the instructions to:

receive, via the communication interface from an end device, a first message that includes an initial registration request and an end device policy request that includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message, wherein the network device is of a core network, and wherein the end device is not registered with the network device;

execute, in response to the receipt of the first message, a registration procedure and a policy control procedure;

determine whether the registration procedure and the policy control procedure are completed;

generate, when the registration procedure and the policy control procedure are completed, a second message that includes a registration response and an end device policy, wherein the first message is received as a non-access stratum message and the second message is transmitted as another non-access stratum message; and

transmit, via the communication interface to the end device, the second message.

10. The network device of claim 9 , wherein the second message includes a registration accept message that includes an information element, wherein the information element includes the end device policy.

11. The network device of claim 9 , wherein the processor further executes the instructions to:

store the end device policy only when the registration procedure is not completed and the policy control procedure is completed.

12. The network device of claim 9 , wherein the processor further executes the instructions to:

transmit, via the communication interface, a registration request to a unified data management device.

13. The network device of claim 9 , wherein the end device policy includes at least one of a route selection policy or an access discovery and selection policy.

14. The network device of claim 9 , wherein the network device is a mobility management entity device or an access and management function device, and the core network includes an evolved packet core network or a next generation core network.

15. The network device of claim 9 , wherein, when determining whether the registration procedure and the policy control procedure are completed, the processor further executes the instructions to:

determine whether a registration response is received from a unified data management device or a home subscriber server; and

determine, in response to a determination that the registration response is received, that the registration procedure is completed.

16. The network device of claim 9 wherein, when determining whether the registration procedure and the policy control procedure are completed, the processor further executes the instructions to:

determine whether a policy control create response is received from a policy control function device or a policy charging and rules function; and

determine, in response to a determination that the policy control create response is received, that the policy control procedure is completed.

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

receive, from an end device, a first message that includes an initial registration request and an end device policy request that includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message, and wherein the end device is not registered with the device;

execute, in response to the receipt of the first message, a registration procedure and a policy control procedure;

determine whether the registration procedure and the policy control procedure are completed;

generate, when the registration procedure and the policy control procedure are completed, a second message that includes a registration response and an end device policy, wherein the first message is received as a non-access stratum message and the second message is transmitted as another non-access stratum message; and

transmit, to the end device, the second message.

18. The non-transitory computer-readable storage medium of claim 17 ,

wherein the second message includes a registration accept message that includes an information element, wherein the information element includes the end device policy.

19. The non-transitory computer-readable storage medium of claim 17 , wherein the instructions further comprise instructions, which when executed cause the device to:

store the end device policy only when the registration procedure is not completed and the policy control procedure is completed.

20. The non-transitory computer-readable storage medium of claim 17 , wherein the device is a mobility management entity device or an access and management function device, and the core network includes an evolved packet core network or a next generation core network.
