Abstract: The present invention relates to a method and apparatus for controlling a connection transfer in a cellular network having at least two systems, such as a GSM system and a WCDMA system. Based on a load determination, a service-based inter-system or inter-frequency handover of the connection to another system or to another carrier of the same system is initiated if the determined is below a threshold and service priorities are indicating it. If it exceeds the threshold, an additional load-based inter-system or inter-frequency handover can be initiated. If the load of the target cell is not known, a load estimation based on a learning process can be used to derive a probability of success of an interfrequency or inter-system handover, which may be used for deciding on the initiation of the inter-system handover. The learning process may be performed by evaluating preceding interfrequency or inter-system handovers to the target cell or preceding interfrequency or inter-system handovers from the target cell.

Abstract: A communications system where data blocks from a communications device are received at least in a serving site over a wireless interface. The serving site typically checks whether data blocks have been correctly received and sends acknowledgement information to the communications device accordingly. An assisting site may also receive the data blocks and send information indicating whether data blocks have been correctly received in the assisting site. In this case, the serving site may request erroneously received information from the assisting site. Alternatively, the assisting site may send information indicating erroneous reception of data blocks in response to noticing a data block sent by the communications device. As a further alternative, the assisting site may be synchronized with the data blocks sent by the communications device and send quality information relating to the wireless interface between the communications device and the assisting site to the serving site.
