Systems and methods for optimized propagation of data change notifications

1 . A method, comprising:

receiving, by a unified data repository (UDR) device and from a unified data management (UDM) device or a policy control function (PCF) device, a subscription request to subscribe to receive a data change notification from the UDR device,

wherein the subscription request includes:

a monitoring indication that identifies a monitored data set associated with a user equipment (UE), and

a report indication that:

identifies an attribute data set associated with the UE, and

indicates a request to receive a report associated with the attribute data set; and

transmitting, by the UDR device to at least one of the UDM device or the PCF device and based on the subscription request, the report and an indication of a subscription to receive the data change notification, wherein the report is based on the report indication.

2 . The method of claim 1 , wherein the monitored data set is associated with at least one of:

subscription data associated with the UE, or

policy data associated with the UE.

3 . The method of claim 1 , wherein the monitored data set and the attribute data set are a same data set.

4 . The method of claim 1 , wherein the monitored data set and the attribute data set are different data sets.

5 . The method of claim 1 , wherein the attribute data set is associated with at least one of:

provisioned data associated with the UE,

subscription data associated with the UE, or

policy data associated with the UE.

6 . The method of claim 1 , further comprising:

detecting, by the UDR device, a data change associated with the monitored data set;

determining, based on detecting the data change, updated data associated with the UE; and

transmitting, by the UDR device and to at least one of the UDM device or the PCF device, an indication of the data change notification based on the subscription,

wherein the data change notification includes an indication of the updated data associated with the UE.

7 . The method of claim 1 , wherein a first interface between the UDM device and the UDR device and a second interface between the PCF device and the UDR device are direct interfaces.

8 . A network device, comprising:

one or more processors configured to:

transmit, via an interface between the network device and a unified data repository (UDR) device, a subscription request to subscribe to receive a data change notification from the UDR device,

wherein the subscription request includes:

a monitoring indication that identifies a monitored data set associated with a user equipment (UE), and

a report indication that:

 identifies an attribute data set associated with the UE, and

 indicates a request to receive a report associated with the attribute data set; and

receive, from the UDR device and based on the subscription request, the report and an indication of a subscription to receive the data change notification, wherein the report is based on the report indication.

9 . The network device of claim 8 , wherein the network device is at least one of a unified data management (UDM) device or a policy control function (PCF) device, and

wherein the one or more processors, to transmit the subscription request to subscribe to receive the data change notification from the UDR device, are configured to:

transmit the subscription request to the UDR device via a direct interface.

10 . The network device of claim 8 , wherein the monitored data set is associated with at least one of:

subscription data associated with the UE, or

policy data associated with the UE.

11 . The network device of claim 8 , wherein the monitored data set and the attribute data set are a same data set.

12 . The network device of claim 8 , wherein the monitored data set and the attribute data set are different data sets.

13 . The network device of claim 8 , wherein the attribute data set is associated with at least one of:

provisioned data associated with the UE,

subscription data associated with the UE, or

policy data associated with the UE.

14 . The network device of claim 8 , wherein the one or more processors are further configured to:

receive, from the UDR device and based on the subscription, the data change notification,

wherein the data change notification includes an indication of updated data associated with the UE.

15 . 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 network device, cause the network device to:

transmit a subscription request to subscribe to receive a data change notification from a unified data repository (UDR) device,

wherein the subscription request includes an immediate report request; and

receive, from the UDR device and based on the subscription request, a communication that includes a report and an indication of a subscription to receive the data change notification based on the subscription request, wherein the report is based on the immediate report request.

16 . The non-transitory computer-readable medium of claim 15 , wherein the network device is a unified data management (UDM) device, and

wherein the one or more instructions, that cause the network device to transmit the subscription request to subscribe to receive the data change notification from the UDR device, cause the network device to:

transmit the subscription request to the UDR device via a direct interface between the UDM device and the UDR device.

17 . The non-transitory computer-readable medium of claim 15 , wherein the network device is a policy control function (PCF) device, and

wherein the one or more instructions, that cause the network device to transmit the subscription request to subscribe to receive the data change notification from the UDR device, cause the network device to:

transmit the subscription request to the UDR device via a direct interface between the PCF device and the UDR device.

18 . The non-transitory computer-readable medium of claim 15 , wherein the data change notification is associated with at least one of:

subscription data associated with a user equipment (UE), or

policy data associated with the UE.

19 . The non-transitory computer-readable medium of claim 15 , wherein the report includes attribute data associated with a user equipment (UE), the attribute data including at least one of:

provisioned data associated with the UE,

subscription data associated with the UE, or

policy data associated with the UE.

20 . The non-transitory computer-readable medium of claim 15 , wherein the one or more instructions, when executed by the one or more processors, further cause the network device to:

receive, from the UDR device and based on the subscription, the data change notification,

wherein the data change notification includes an indication of updated data associated with a user equipment (UE).
