ABSTRACT:
An object of the present invention is to provide an improved real-time application performance for user equipments. The object is achieved by a method for bi-casting real time data packets in a mobile system node. The node is comprised in a mobile system, which mobile system comprises an old Node-B and a new Node-B. The old Node-B and the new Node-B are adapted to be connected to the node. The mobile system further comprising a user equipment 130 adapted for switching the receipt of real time data packets from the old Node-B to the new Node-B. The method comprises the steps of associating a first sequence number with a first real time data packet adapted to be sent to the old Node-B, and associating a second sequence number with the same first real time data packet adapted to be sent to the new Node-B. The second sequence number is different from the first sequence number.
