1. A method for communicating non-Internet Protocol data over a packet data network (PDN) of PDN type IPv4, IPV6, or IPv4IPv6, the method being performed by a core network gateway node, the method comprising:
acquiring an indication of a wireless device to communicate header-less with the wireless device, wherein the indication is provided in Protocol Configuration Options (PCO) information elements or Additional Protocol Configuration Options (APCO) information elements received from the wireless device;
determining based on the indication whether to remove an Internet protocol (IP) header;
in response to removing the IP header, reserving an, IP address for the wireless device without providing the IP address to the wireless device, wherein the wireless device is not able to implement an IP stack and a user datagram protocol (UDP) stack to communicate using the IP address;
communicating IP packets over the packet data network of PDN type IPV4, IPv6, or IPv4IPv6 with an application server, said IP packets comprising an IP header that comprises the IP address of the wireless device and a UDP header; and
communicating header-less payload packets without IP headers over a PDN connection with said wireless device by mapping the IP address to a Tunnel endpoint identifier (TEID), and removing the IP header and the UDP header from all IP packets communicated to the wireless device from the core network gateway node before forwarding the header-less payload packets to the wireless device without providing the IP address to the wireless device,
wherein said header-less payload packets that are communicated without IP headers represent said non-IP data.
