Abstract

A method, a network device, a system, and a non-transitory computer-readable storage medium are described in relation to an gateway type monitoring event service. The gateway type monitoring event service may include providing a current gateway type associated with an end device and a network to an application function. The current gateway type may be used by the application function to perform a network operation or procedure.

First claim

What is claimed is:

1 . A method comprising:
receiving, by a network device from a first network device, a request for a current gateway type associated with an end device; querying, by the network device a subscription storage device, subscription information pertaining to the end device; determining, by the network device based on the querying, that the end device is subscribed to a gateway type monitoring; querying, by the network device a mobility management device, for the current gateway type; and transmitting, by the network device to the first network device, a first response that includes current gateway type data.

2 . The method of claim 1 , wherein the network device includes a service capability exposure function.

3 . The method of claim 1 , further comprising:
applying the current gateway type data of the end device to a network operation or procedure.

4 . The method of claim 3 , wherein the network operation pertains to an establishment of a first application session between the first network device and the end device, or a modification of an active second application session between the first network device and the end device.

5 . The method of claim 1 , wherein the current gateway type data indicates a packet data network gateway (PGW), a PGW-control plane (PGW-C) plus a session management function (SMF), or that the end device is not connected.

6 . The method of claim 1 , further comprising:
determining, by the network device based on the querying of the subscription storage device, that the first network device has permission to access the current gateway type.

7 . The method of claim 1 , wherein the request includes a unique identifier of the end device and a unique identifier of the first network device pertaining to the gateway type monitoring.

8 . The method of claim 1 , wherein the first network device includes an application function (AF) that hosts an application service external from a core network of the network device.

9 . A system comprising:
a network device, wherein the network device comprises a first processor configured to:
receive, from a first network device, a request for a current gateway type associated with an end device;
query, a subscription storage device, subscription information pertaining to the end device;
determine, based on a result of the query, that the end device is subscribed to a gateway type monitoring;
query, a mobility management device, for the current gateway type; and
transmit to the first network device, a first response that includes current gateway type data.

10 . The system of claim 9 , further comprising:
the first network device, wherein the first network device comprises a second processor configured to: apply the current gateway type data of the end device to a network operation or procedure.

11 . The system of claim 10 , wherein the network operation pertains to an establishment of a first application session between the first network device and the end device, or a modification of an active second application session between the first network device and the end device.

12 . The system of claim 9 , wherein the network device includes a service capability exposure function.

13 . The system of claim 9 , wherein the current gateway type data indicates a packet data network gateway (PGW), a PGW-control plane (PGW-C) plus a session management function (SMF), or that the end device is not connected.

14 . The system of claim 9 , wherein the first processor is further configured to:
determine, based on the query of the subscription storage device, that the first network device has permission to access the current gateway type.

15 . The system of claim 9 , wherein the request includes a unique identifier of the end device and a unique identifier of the first network device pertaining to the gateway type monitoring.

16 . The system of claim 9 , wherein the first network device includes an application function (AF) that hosts an application service external from a core network of the network device.

17 . A non-transitory computer-readable storage medium storing instructions executable by a processor of a network device, wherein the instructions are configured to:
receive, from a first network device, a request for a current gateway type associated with an end device; query, a subscription storage device, subscription information pertaining to the end device; determine, based on a result of the query, that the end device is subscribed to a gateway type monitoring; query, a mobility management device, for the current gateway type; and transmit to the first network device, a first response that includes current gateway type data.

18 . The non-transitory computer-readable storage medium of claim 17 , wherein the instructions are further configured to:
determine, based on the query of the subscription storage device, that the first network device has permission to access the current gateway type.

19 . The non-transitory computer-readable storage medium of claim 17 , wherein the request includes a unique identifier of the end device and a unique identifier of the first network device pertaining to the gateway type monitoring.

20 . The non-transitory computer-readable storage medium of claim 17 , wherein the current gateway type data indicates a packet data network gateway (PGW), a PGW-control plane (PGW-C) plus a session management function (SMF), or that the end device is not connected.
