Abstract
In a mobile communications system (BSS, SGSN, GGSN) having a packet data transmission capability, a dynamic packet-based quality of service (QoS) mechanism is provided within a “transmission tunnel” defined by a more static packet data protocol context (PDP context). More particularly, each data packet is arranged to carry at least one QoS parameter, and the scheduling and the policing of the transmission of the data packets is made in packet by packet basis according to this QoS information in the packets, while, however, within the limits set by the PDP context. This concept enables to have any number of QoS profiles in use simultaneously, e.g. a dedicated QoS profile for each of several Internet user applications run in the mobile station (MS) for a IP address. Therefore, the present invention provides support for various Internet applications and their QoS requirements. Moreover, the QoS can be changed at any time after activation of the PDP context, since only the QoS information in the relevant data packets has to be changed.
