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: perform a Packet Data Protocol, PDP, Context Activation procedure with a wireless device, wherein during the PDP Context Activation procedure the CN node is informed that when the CN node receives an Internet Protocol, 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 a certain action; receive, from another CN node, an IP packet which indicates that the wireless device is being requested to perform the certain action; determine whether the received IP packet which was originated by an 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 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: perform a Packet Data Protocol, PDP, Context Activation procedure with a wireless device, wherein during the PDP Context Activation procedure the CN node is informed that when the CN node receives an Internet Protocol, 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 a certain action; receive, from another CN node, an IP packet which indicates that the wireless device is being requested to perform the certain action; determine whether the received IP packet which was originated by an 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 perform a Packet Data Protocol, PDP, Context Activation procedure with a wireless device, wherein during the PDP Context Activation procedure the CN node is informed that when the CN node receives an Internet Protocol, 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 a certain action; receive, from another CN node, an IP packet which indicates that the wireless device is being requested to perform the certain action; determine whether the received IP packet which was originated by an 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
