Systems and methods for exposing user equipment identity

The method of claim 4, wherein the subscriber identifier message further includes information identifying a trigger event for the subscriber identifier message, wherein the trigger event includes at least one of:

• the UE device attaching to the core network via the RAN,
• the UE device detaching from the core network,
• an Internet Protocol (IP) address or port being allocated to the UE device, or
• an IP address or port being deallocated for the UE device.

A device comprising:

• a processor configured to:
• expose services or capabilities to application servers outside the core network, wherein the device is located in a core network associated with a radio access network (RAN);
• receive a subscriber identifier message from a gateway device that established a connection to a user equipment (UE) device via the RAN, wherein the subscriber identifier message includes information identifying the UE device;
• receive a request from an application server associated with the connection for the information identifying the UE device;
• and
• provide the requested information identifying the UE device to the application server, in response to receiving the request from the application server.

A system comprising:

• a first device configured to:
• establish a connection to a user equipment (UE) device via a radio access network (RAN);
• and
• a second device configured to:
• expose services or capabilities to application servers outside a core network, wherein the device is located in the core network associated with the RAN;
• wherein the first device is further configured to:
• send a subscriber identifier message to the second device in response to establish the connection to the UE device, wherein the subscriber identifier message includes information identifying the UE device;
• and
• wherein the second device is further configured to:
• receive a request from an application server associated with the connection for the information identifying the UE device;
• and
• provide the requested information identifying the UE device to the application server, in response to receiving the request from the application server.
