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 a service application is executed in the source node for the wireless device by the service session. In particular, the amount of application data to be transferred from the source node to the target node for a wireless device that is handed over from a first base station to a second base station can be reduced by truncating the application data by an amount corresponding to the data pending in a downlink buffer at the first base station. Thereby, the target node is able to recreate the complete application buffer from the truncated application data and data from the downlink buffer, the latter data being transferred from the first base station () to the second base station (), according to a handover procedure.
