METHOD FOR OPTIMISING DATA TRANSMISSION IN A PACKET SWITCHED WIRELESS DATA TRANSMISSION SYSTEM

摘要

The invention relates to a method for optimising the transfer of information between one or more applications run in a mobile terminal (MT) and a packet-switched network (NW). There are at least two PDP contexts (PDP1-PDP9) available in the packet-switched network (NW), which have at least partly different data transfer properties, whereby the PDP contexts (PDP1-PDP9) can provide at least partly different qualities of service for the transfer of information. The method is characterised in that when the quality of service specified for the application connection changes, it is examined on the basis of the properties of the PDP context (PDP1-PDP9) available in the packet-switched network (NW) which of the PDP contexts (PDP1-PDP9) is suitable for use by the application connection with the changed quality of service, and the one of the PDP contexts (PDP1-PDP9), the data transfer properties of which are the closest to the changed quality of service is selected for the application connection.
