| 1. A method for choosing a connection-specific channel coding and/or interleaving scheme comprising:
requesting a specific communication connection over a radio interface between a mobile terminal and a base station of a cellular
packet radio system;
as part of said requesting a specific communication connection, communicating a request message, said request message indicating
a need for setting up a new radio bearer between the mobile terminal and the base station or changing the characteristics
of an existing radio bearer between the mobile terminal and the base station, said request message further indicating a certain
set of desired Quality of Service parameters selected based on an expected use of said specific communication connection,
to be associated with said requested specific communication connection,
allocating a first channel coding and/or interleaving scheme for independent application to said specific communication connection
based, at least in part, on said desired Quality of Service parameters;
mapping said desired set of Quality of Service parameters to said allocated channel coding and/or interleaving scheme as a
part of the allocation of the channel coding and/or interleaving scheme; and
communicating said allocated channel coding and/or interleaving scheme to the base station and the mobile terminal for them
to independently apply said first channel coding and/or interleaving scheme for use in said specific communication connection.
