It is described a mobile network with a first network node and a second network node, the mobile network providing a user plane for transporting transmission packets, which contain user data, and a further network layer plane different from the user plane. A method of operating the first network node includes sending an information element to the second network node via a network layer protocol of the further network layer plane wherein the information element indicates optimizing capabilities of the first network node or of a other network node of the mobile network of processing an optimized transmission packet. A method of operating a second network node includes receiving the information element from the first network node via a network layer protocol of the further network layer plane, and processing the information element.

Mobile network optimization

In one exemplary aspect of this invention a method includes receiving at a user equipment from a wide area network access node information identifying at least one predetermined radio frequency carrier; initiating, in response to a presence of an interferer on a radio frequency carrier that is being used for a current connection between the user equipment and the network access node, a connection re-establishment procedure, where the interferer has the potential to cause a radio link failure of the current connection on the radio frequency carrier; and transmitting a connection re-establishment request to the network access node on the predetermined radio frequency carrier. The interferer can be a closed subscriber group network access node that the user equipment is not authorized to gain access to.
