Abstract: In order to allow efficient differentiated handling of network traffic in a network section, a network address translator (120) performs network address translation on incoming data packets to be transmitted into the network section and/or on outgoing data packets transmitted from the network section. In the incoming data packets, the network address translation replaces a source network address with a replacement network address. In the outgoing data packets, a replacement network address is included in place of a destination address, and the network address translation replaces the replacement network address with the destination network address. In each case, the replacement network address is selected according to a traffic class of the data packet. In the network section, differentiated handling of the data packets on the basis of the replacement network address is provided.

Abstract: The present invention describes a method for operation and maintenance of Access Points in a wireless communications network, and a network node and an access point for use in such a network. Access points are used for connecting wireless networks to core networks. The method comprises the step of first receiving, at a network node, an on-demand triggered request for status information, wherein the request includes an access point identity. The network node investigates, using the received access point identity, if the access point is registered within the network. If the access point is registered within the network, then as a first following step, the network node uses the access point identity to retrieving access point address information from storing means. In a second following step, the network node uses the retrieved address information to establish a connection to the access point. Thereafter the network node receives access point status information.
