Plural packet data units are encapsulated into a datagram of a user datagram protocol. Each of the plural packet data units includes a respective header of a tunneling protocol and a respective user data packet. Each of the headers indicates a length of the respective packet data unit. The plural packet data units include a first packet data unit and are arranged in the datagram in an order starting with the first packet data unit. It is informed, by at least the header of the first packet data, that the encapsulating encapsulates the plural packet data units into the datagram.

Sending multiple G-PDUs with a single UDP datagram

An apparatus is disclosed which according to an embodiment is configured to store a direct tunnel context. The direct tunnel context comprises a field or flag indicating whether or not a direct tunnel is established between the apparatus and a radio network, and further comprises at least one of a tunnel endpoint identifier and an address of a user plane of a serving node. The direct tunnel context optionally further comprises at least one of a tunnel endpoint identifier and an address of a user plane of a controller of the radio network. The apparatus may be a gateway or a gateway general packet radio service support node. The invention further provides a method, system, device and program suitable or configured to handle such direct tunnel contexts.
