Patent attributes
The present invention proposes a method for configuring a data transmission interface in a communication network adopting a transmission protocol for transmission of data in units of grouped data, wherein said transmission interface is the interface (Iub) between an access network control node (RNC1) and an access node (BS1-BS6) adapted to establish a communication to a terminal, and wherein said communication network has a topology such that an access node (BS2, BS3, BS5, BS6) is connected to said access network control node (RNC1) by an intermediate of at least one further access node (BS1,BS1-BS2, BS4, BS4), said method comprising the steps of: deriving a delay information of the delay experienced by data transmission between a respective network access node (BS1-BS6) and said access network control node (RNC), calculating a delay difference between two consecutive access nodes (BS1-BS2, BS2-BS3, BS4-BS5, BS4-BS6) based on said delay information, and modifying the delay experienced by data transmission for the respective access node which is identified by the respective smaller delay. Also, the present invention proposes an accordingly adapted access network control node as well as accordingly adapted access nodes.
