| 1. A method comprising:
allocating data transmission resources in a packet-switched telecommunications system including a terminal and a fixed network
to which an operational entity is defined for defining resources for a radio bearer, the allocating further comprising:
defining a compression method of header fields in data packets used on the radio bearer, said compression method requiring
a bi-directional connection, and, after defining the compression method,
defining the radio bearer resources for the terminal on the basis of an application used by the terminal on said radio bearer
in such a manner that said resources also comprise the capacity required by the defined compression method of header fields
in data packets.
