Abstract: A network node (21), which is placed within a core network, stores a list of network elements (24) capable of forwarding a trigger message to a MTC device (10). The network node (21) receives the trigger message from a transmission source (30, 40) placed outside the core network, and then selects, based on the list, one of the network elements to forward the trigger message to the MTC device (10). The MTC device (10) validates the received trigger message, and then transmits, when the trigger message is not validated, to the network node (21) a reject message indicating that the trigger message is not accepted by the MTC device (10). Upon receiving the reject message, the network node (21) forwards the trigger message through a different one of the network elements, or forwards the reject message to transmission source (30, 40) to send the trigger message through user plane.

Abstract: In a transceiver, the accuracy of a packet time stamp can be improved by compensating for errors introduced by processing of the packet. A received packet can be received via multiple lanes. A packet time stamp can be measured using a start of frame delimiter (SFD). A last arriving lane can be used to provide a recovered clock signal.

Also, a serializer-deserializer delay associated with the last arriving lane can be used to adjust the time stamp.

The communication device can thus decide if the predicted QoS is sufficient for the planned activity and may take a decision to either start the activity, postpone the activity or alter the activity.
