摘要： The present application relates to packet data communications over radio links and change of base station. Particularly it relates to base station handover of packet switched communications in GPRS (General Packet Radio System) and UMTS (Universal Mobile Telecommunications System) communications. The invention is directed in particular to a base station change of lossless type allowing lossless base station change of packet switched communications in unacknowledged mode between a mobile station and a support node, wherein the support node acting as source support node during the base station change forwards maintained sequence number information to the support node acting as target support node, when the source and target support nodes are different.
