System and method for delivery of end device policies during registration procedure
A method, a device, and a non-transitory storage medium are described in which policy delivery is provided. A network device of a core network may receive a registration request message that includes a request for an end device policy. The network device may perform a registration procedure and a policy procedure pertaining to an end device. The network device determines when the registration and the policy procedures are completed. The network device transmits a registration response that includes an end device policy to an end device.
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, and wherein the end device is not registered with the network device and the core network;
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; 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 that includes the end device policy.
3. The method of claim 1 , wherein the first message is received as a non-access stratum message and the second message is transmitted as a non-access stratum message.
4. The method of claim 1 , wherein the end device policy request includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message.
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, wherein the network device is of a core network and the end device is not registered with the network device and the core network;
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; 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 that includes the end device policy.
11. The network device of claim 9 , wherein the first message is received as a non-access stratum message and the second message is transmitted as a non-access stratum message.
12. The network device of claim 9 , wherein the end device policy request includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message.
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, wherein the end device is not registered with the device and the core network;
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; 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 that includes the end device policy.
19. The non-transitory computer-readable storage medium of claim 17 ,
wherein the end device policy request includes a User Equipment (UE) Policy Section Identifier (UPSI) List Transport message.
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.
