Abstract

Source and target service nodes and methods are described, for transferring a service session for a wireless device from the source node to the target node when the wireless device is handed over from a first base station associated with the source node to a second base station associated with the target node. A first data amount indication is obtained, which indicates how much downlink data is pending at the first base station. The first base station is requested to delete some or all pending downlink data from a downlink buffer, and the source node transfers to the target node application data and a data amount indication related to a first data amount indication. The target node can then recreate the downlink buffer at the second base station by sending a first part of the application data, corresponding to the second data amount indication, to the second base station.
