Abstract:
1. A method, comprising: assigning an identifier to at least one data unit of a data flow, wherein said identifier associates said at least one data unit of said data flow with a first entity in a first network node, and without pre-negotiating setup of said data flow by exchange of setup signalling prior to actual transfer of said at least one data unit of said data flow, transferring said at least one data unit of said data flow from said first network node to a second network node; wherein establishment of a second entity in said second network node, which does not exist at a reception of a first data unit of said at least one data unit at said second network node, is enabled by said transferring said at least one data unit of said data flow to said second network node upon said reception of said first data unit of said at least one data unit and is associated with said at least one data unit via said identifier, and implementing, by said first entity, a function for joint implementation by said second entity in said second network node and related to said transferring of said at least one data unit of said data flow from said first network node to said second network node.
