Abstract:
1. A subscriber terminal on a subscriber terminal side of a communication system including on a network side a packet data communication system having a base station system, for performing a user packet data transfer between said subscriber terminal side and said base station system on said network side, comprising: a radio communication link between said base station system on said network side and said subscriber terminal side; radio resources for facilitating said user data packet transfer on said radio communication link; a physical connection controller for performing said user data packet transfer on said radio communication link between said base station system and said subscriber terminal side by scheduling said user data packets as a number of radio blocks on said radio resources on said radio communication link, said physical connection indicating in the subscriber terminal side and the network side that the subscriber terminal side and the network side are included in a radio resources scheduling process for performing said user data packet transfer; a transmission buffer comprising a subscriber terminal side transmission queue wherein said user data packets enter said transmission queue with respective inter-arrival times; a transmission detector including an active period detector for monitoring, for the user data packet transfer between said network side and said subscriber terminal side, the inter-arrival time of user data packets into said transmission queue by respectively detecting the user data packets arriving into the transmission queue and determining as inter-arrival time respectively the time between two detected user data packets and for determining as an active period the period from a first detected user data packet to a last detected user data packet for which each determined inter-arrival time falls in a predetermined range; and wherein said physical connection controller further includes a physical connection maintaining device to maintain said physical connection between said subscriber terminal side and said network side in said active period.
