The processor may be configured to subscribe with a second network exposure device in the second core network to receive telemetry information notifications for the UE device, in response to receiving the indication; receive a telemetry information notification for the UE device from the second network exposure device; and report telemetry information obtained from the received telemetry information notification to a server device associated with the UE device ## Claims ### Claim 1 A method comprising: receiving, by a device in a core network associated with a Radio Access Network (RAN), an indication from a subscriber management device that a user equipment (UE) device has attached to a second core network; subscribing, by the device, with a second network exposure device in the second core network to receive telemetry information notifications for the UE device, in response to receiving the indication; receiving, by the device, a telemetry information notification for the UE device from the second network exposure device; and reporting, by the device, telemetry information obtained from the received telemetry information notification to a server device associated with the UE device. ### Claim 2 (depends on 1) The method of claim 1, wherein subscribing to receive the telemetry information includes: sending a subscription request to the second network exposure device via an interface. ### Claim 3 (depends on 1) The method of claim 1, wherein reporting the telemetry information obtained from the received telemetry information notification to the server device associated with the UE device includes: sending a telemetry report to the server device via an interface. ### Claim 4 (depends on 1) The method of claim 1, further comprising: subscribing with a telemetry device in the core network to receive telemetry information notifications for the UE device; and reporting telemetry information notifications for the UE device from the telemetry device to the server device. ### Claim 5 (depends on 4) The method of claim 4, wherein subscribing with a telemetry device in the core network to receive telemetry information notifications for the UE device includes: sending a subscription request to the telemetry device via a T9 interface. ### Claim 6 (depends on 1) The method of claim 1, further comprising: subscribing with the subscriber management device to receive roaming status notifications for the UE device; and reporting roaming status notifications for the UE device received from the subscriber management device to the server device. ### Claim 7 (depends on 1) The method of claim 1, wherein the telemetry information notification for the UE device includes at least one of: a signal strength or a signal quality parameter value for the UE device. ### Claim 8 (depends on 1) The method of claim 1, wherein the telemetry information notification for the UE device includes at least one of: congestion information for a connection associated with the UE device; and a loss of connection information for a connection associated with the UE device. ### Claim 9 (depends on 1) The method of claim 1, wherein the core network is part of a home network and the second core network is part of a visited network. ### Claim 10 (depends on 1) The method of claim 1, wherein the device includes a first Service Capabilities Exposure Function (SCEF) in the core network, and wherein the second network exposure device includes a second SCEF device. ### Claim 11 (depends on 1) The method of claim 1, wherein the device includes a first Network Exposure Function (NEF) in the core network, and wherein the second network exposure device includes a second NEF device. ### Claim 12 A device comprising: a processor configured to: receive an indication from a subscriber management device that a user equipment (UE) device has attached to a second core network, wherein the device is in a core network associated with a Radio Access Network (RAN); subscribe with a second network exposure device in the second core network to receive telemetry information notifications for the UE device, in response to receiving the indication; receive a telemetry information notification for the UE device from the second network exposure device; and report telemetry information obtained from the received telemetry information notification to a server device associated with the UE device. ### Claim 13 (depends on 12) The device of claim 12, wherein, when subscribing to receive the telemetry information notifications for the UE device, the processor is further configured to: send a subscription request to the second network exposure device via an interface. ### Claim 14 (depends on 12) The device of claim 12, wherein, when reporting the telemetry information obtained from the received telemetry information notification to the server device associated with the UE device, the processor is further configured to: send a telemetry report to the server device via an interface. ### Claim 15 (depends on 12) The device of claim 12, wherein the processor is further configured to: subscribe with a telemetry device in the core network to receive telemetry information notifications for the UE device by sending a subscription request to the telemetry device via an interface; and report telemetry information notifications for the UE device from the telemetry device to the server device. ### Claim 16 (depends on 12) The device of claim 12, wherein the processor is further configured to: subscribe with the subscriber management device to receive roaming status notifications for the UE device; and report roaming status notifications for the UE device from the subscriber management device to the server device. ### Claim 17 (depends on 12) The device of claim 12, wherein the telemetry information notification for the UE device includes at least one of: a signal strength or quality parameter value for the UE device; congestion information for a connection associated with the UE device; or loss of connection information for a connection associated with the UE device. ### Claim 18 (depends on 12) The device of claim 12, wherein the device includes a first Service Capabilities Exposure Function (SCEF) in the core network, and wherein the second network exposure device includes a second SCEF device. ### Claim 19 (depends on 12) The device of claim 12, wherein the device includes a first Network Exposure Function (NEF) in the core network, and wherein the second network exposure device includes a second NEF device. ### Claim 20 A non-transitory computer-readable memory device storing instructions executable by a processor, the non-transitory computer-readable memory device comprising: one or more instructions to receive an indication from a subscriber management device that a user equipment (UE) device has attached to a second core network, wherein the device is in a core network associated with a Radio Access Network (RAN); one or more instructions to subscribe with a second network exposure device in the second core network to receive telemetry information notifications for the UE device, in response to receiving the indication; one or more instructions to receive a telemetry information notification for the UE device from the second network exposure device; and one or more instructions to report telemetry information obtained from the received telemetry information notification to a server device associated with the UE device.
