A communication node operable with a communications system that implements an enhanced multi-level precedence and preemption, eMLPP, scheme, the communication node comprising: an input unit to receive from a remote terminal an incoming connection establishment communication having a priority-header value of the remote terminal that indicates a priority for a connection to be established from the remote terminal; an output unit to transmit an outgoing connection establishment communication having an eMLPP value that indicates a precedence and preemption level for the connection to be established; a priority mapper to map priority-header priorities to eMLPP levels, said priority mapper including a priority association data structure that associates one or more priority-header priorities to each of multiple eMLPP levels, the priority association data structure including an entry that associates the priority-header value with the eMLPP value; and a priority mapping controller to accept the incoming connection establishment communication from said input unit, to extract the priority-header value from the incoming connection establishment communication, to provide the priority-header value to said priority mapper, to accept from said priority mapper the eMLPP value that is associated with the priority-header value, and to forward the eMLPP value to said output unit, wherein the communication node comprises an internet protocol, IP, multimedia core network subsystem, IMS, node (302, 706); and wherein: the IMS node (302, 706) is adapted to store the eMLPP value in association with an identifier for the remote terminal for which the connection is to be established; the IMS node is adapted to receive a request from a mobile gateway application server for the eMLPP value that is associated with the remote terminal during a handover of the remote terminal from a first technological domain (702) to a second technological domain (702); and the IMS node is adapted to send the eMLPP value that is associated with the remote terminal to the mobile gateway application server so that the mobile gateway application server can provide the eMLPP value to the second technological domain (702). an input unit to receive from a remote terminal an incoming connection establishment communication having a priority-header value of the remote terminal that indicates a priority for a connection to be established from the remote terminal; an output unit to transmit an outgoing connection establishment communication having an eMLPP value that indicates a precedence and preemption level for the connection to be established; a priority mapper to map priority-header priorities to eMLPP levels, said priority mapper including a priority association data structure that associates one or more priority-header priorities to each of multiple eMLPP levels, the priority association data structure including an entry that associates the priority-header value with the eMLPP value; and a priority mapping controller to accept the incoming connection establishment communication from said input unit, to extract the priority-header value from the incoming connection establishment communication, to provide the priority-header value to said priority mapper, to accept from said priority mapper the eMLPP value that is associated with the priority-header value, and to forward the eMLPP value to said output unit, wherein the communication node comprises an internet protocol, IP, multimedia core network subsystem, IMS, node (302, 706); and wherein: the IMS node (302, 706) is adapted to store the eMLPP value in association with an identifier for the remote terminal for which the connection is to be established; the IMS node is adapted to receive a request from a mobile gateway application server for the eMLPP value that is associated with the remote terminal during a handover of the remote terminal from a first technological domain (702) to a second technological domain (702); and the IMS node is adapted to send the eMLPP value that is associated with the remote terminal to the mobile gateway application server so that the mobile gateway application server can provide the eMLPP value to the second technological domain (702). the IMS node (302, 706) is adapted to store the eMLPP value in association with an identifier for the remote terminal for which the connection is to be established; the IMS node is adapted to receive a request from a mobile gateway application server for the eMLPP value that is associated with the remote terminal during a handover of the remote terminal from a first technological domain (702) to a second technological domain (702); and the IMS node is adapted to send the eMLPP value that is associated with the remote terminal to the mobile gateway application server so that the mobile gateway application server can provide the eMLPP value to the second technological domain (702).
