Allocating data transmission resources in packet-switched data transmission
First Claim
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.

Abstract
A method of allocating data transmission resources in a packet-switched telecommunications system which comprises a terminal and a fixed network to which an operational entity is defined for defining resources for a radio bearer. Radio bearer resources are defined for the terminal on the basis of an application used on the radio bearer, and the used compression method of header fields in data packets is selected before the radio bearer resources are defined, the resources being defined in such a manner that they also comprise the capacity required by the selected compression method of header fields in data packets. The compression methods of header fields in data packets, which are supported by the terminal, are transmitted to the operational entity in the fixed network for defining the compression method to be used. Capacity is defined for the radio bearer in two directions, if the selected compression method of header fields in data packets requires a bi-directional connection.

8. A packet-switched telecommunications system including:
-
a terminal, and a fixed network which comprises an operational entity for defining resources for a radio bearer, in which system a compression method of header fields in data packets used on the radio bearer is configured to be defined, said compression method requiring a bi-directional connection, and after the compression method being defined the resources of the radio bearer are configured to be defined 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. - View Dependent Claims (9, 10)
