Patent ID: 7260080

Claim:
A method comprising: configuring a plurality of compression methods in a terminal communicating with a packet-switched mobile system, wherein characteristics parameters are specified for a terminal, the characteristic parameters comprising at least one of the compression methods supported by the terminal, and wherein a functional entity is configured in a radio network for configuring the compression method to a radio bearer, the method further comprising: configuring at least one of the compression methods in the system on simultaneous radio bearers of the terminal in said functional entity on the basis of the characteristics parameters transmitted by the terminal, allowing a user of the terminal to update the parameters specifying the compression methods of the terminal in the terminal, modifying the characteristics parameters of the terminal in accordance with said update, transmitting the modified characteristics parameters to said functional entity comprised by the radio network, and configuring the use of a compression method for each simultaneous radio bearer on the basis of the modified characteristics parameters; and wherein the packet-switched mobile system is the UMTS system and the functional entity of the radio network for specifying the compression method for a radio bearer comprising a radio resource control protocol and a message specifying the characteristics parameters is a UE capability information message comprising at least a selection parameter for the header field compression method for data packets supported by a convergence protocol of the terminal.
