The present invention relates to a method and network device for selecting a combining point at which at least two redundant transmission paths are combined to a single transmission path in a transmission network comprising at least two selectable combining points (B-J). The combining point is selected by a method using at least two measurement-based selection criteria to which different priorities are allocated. The selection result of a selection criterion with a higher priority is used as a constraint for a selection based on a selection criterion with a lower priority. The selection criteria are applied to lengths or loads of the redundant transmission paths or the single transmission path. Thereby, an optimized combining point can be obtained to thereby lower delays for combined traffic and increase efficiency of network utilization.

The present invention concerns a method and system for avoiding unnecessary handovers, relocations and/or anchoring during packet calls in a wireless telecommunication system. Data to be sent to a mobile terminal is stored in a data buffer. The data is sent to the mobile terminal when the amount of data in the buffer exceeds a predetermined threshold value. When a relocation or anchoring request is received, relocation or anchoring is performed only if one or more conditions are fulfilled. The conditions are preferably timers or adaptive thresholds. In a preferred embodiment, anchoring is performed only if a first timer has expired and relocation is performed only if the first and the second timers have both expired. When a handover is done, it triggers either anchoring or relocation. Therefore, the present invention lowers the number of handovers needed, and thus the number of anchoring and relocation cases.
