Patent ID: 6847610

Claim:
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), in which packet-switched network (NW) there are at least two PDP contexts (PDP 1 -PDP 9 ) available, which PDP contexts have at least partly different data transfer properties, whereby said PDP contexts (PDP 1 -PDP 9 ) can provide at least partly different qualities of service for the transmission of information, and in which method at least one application connection is established for at least one of said applications, for which application connection a quality of service is specified, and one of said PDP contexts (PDP 1 -PDP 9 ) is selected for the application connection, characterised in that when the quality of service specified for the application connection of the application changes, it is examined on the basis of the properties of the PDP contexts (PDP 1 -PDP 9 ) available in the packet-switched network (NW) which of said PDP contexts (PDP 1 -PDP 9 ) is suitable for use by the application connection with the changed quality of service, and the one of the PDP contexts (PDP 1 -PDP 9 ) the data transfer properties of which are closest to the changed quality of service is selected for the application connection.
