Abstract
A first Core Network (CN) node (e.g., Gateway GPRS Support Node), a second CN node (e.g., Serving GPRS Support Node) and a wireless access node (e.g., Base Station Subsystem) are described herein that are configured to efficiently deliver a network triggered report notification to a wireless device (e.g., Internet of Things device).
Claims14
A core network (CN) node within a wireless communication system, the CN node comprising:
- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the CN node is operable to:
- receive, from another CN node, an indication that a wireless device is being requested to perform a certain action;
- transmit, to at least one wireless access node, a paging request message in response to receiving the indication, wherein the paging request message indicates that the wireless device is being requested to perform the certain action;
- wherein the indication is provided by an Internet Protocol (IP) packet originated by an external node, wherein the certain action is to transmit a specific type of report from the wireless device to the external node, and wherein the CN node, prior to performing the transmit operation, is further operable to:
- determine that the IP packet originated by the external node includes information to trigger the wireless device to transmit the specific type of report to the external node by:
- extracting User Datagram Protocol (UDP) port information from the IP packet;
- and
- determining, from the extracted UDP port information, a UDP source port number and a UDP destination port number, wherein the UDP source port number indicates a network triggered report request and the UDP destination port number indicates a specific type of report.

- a processor;
- and,
- a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the CN node is operable to:
- receive, from another CN node, an indication that a wireless device is being requested to perform a certain action;
- and,
- transmit, to at least one wireless access node, a paging request message in response to receiving the indication, wherein the paging request message indicates that the wireless device is being requested to perform the certain action;
- wherein the indication is provided by an Internet Protocol (IP) packet originated by an external node, and wherein the CN node, prior to performing the receive operation, is further operable to:
- perform a Packet Data Protocol (PDP) Context Activation procedure with the wireless device, wherein during the PDP Context Activation procedure the CN node is informed that when the CN node receives an IP packet that is associated with the wireless device and has a payload that is less than a threshold of X octets then that IP packet is to be considered as a trigger for the wireless device to perform the certain action;
- determine whether the received IP packet which was originated by the external node has a payload that is less than the threshold of X octets;
- based on the determination that the received IP packet has a payload that is less than the threshold of X octets, transmit, to at least one wireless access node, a paging request message that indicates that the wireless device is being requested to perform the certain action;
- and,
- based on the determination that the received IP packet has a payload that is greater than or equal to the threshold of X octets, transmit, to the at least one wireless access node, a paging request message that does not indicate that the wireless device is being requested to perform the certain action.

A method in a core network (CN) node within a wireless communication system, the method comprising:
- receiving, by the CN node from another CN node, an indication that a wireless device is being requested to perform a certain action;
- and,
- transmitting, by the CN node to at least one wireless access node, a paging request message in response to receiving the indication, wherein the paging request message indicates that the wireless device is being requested to perform the certain action;
- wherein the indication is provided by an Internet Protocol (IP) packet originated by an external node, wherein the certain action is to transmit a specific type of report from the wireless device to the external node, and wherein the method further comprises, prior to the transmitting step:
- determining that the IP packet originated by the external node includes information to trigger the wireless device to transmit the specific type of report to the external node by:
- extracting User Datagram Protocol (UDP) port information from the IP packet;
- and
- determining, from the extracted UDP port information, a UDP source port number and a UDP destination port number, wherein the UDP source port number indicates a network triggered report request and the UDP destination port number indicates a specific type of report.
