Abstract (en)

[origin: WO9852327A2] The invention relates to packet-switched transmission of calls and particularly to real-time packet-switched transmission of speech calls. The object of the invention is to provide a method that allows efficient use of the transmission capacity without impairing the quality of real-time calls: information can here be transmitted by a packet-switched method so that the transmission delays remain short and the transmission delay of one and the same call does not vary at the receiving end. The method of the invention comprises defining a repetition period (R) that is notably longer than the duration of the transmission of a single packet, defining the starting point (0) of the repetition period, receiving a packet (2), allocating a time slice (1') of the same duration as the packet from the repetition period for the connection that the packet is associated with, and transmitting the packet in the time slice allocated and when a new packet associated with the same connection is received, transmitting the packet in the time slice allocated for the connection. Another object of the invention is to provide a network node in a data transmission network.
