Abstract

Method and radio station for transmitting information via a GSM mobile radio network. When information, in particular packetized data, is being transmitted via a GSM mobile radio network, the context definition for the radio interface between the mobile station and the base station takes place at a different time from the setting up of the physical traffic relationships, and thus uses the radio resources for this physical traffic relationship more efficiently.

Claims

1. A method for transmitting information via a mobile radio network, the transmitted information representing packetized data, comprising the steps of:

defining a context, before setting up a traffic relationship between a mobile station and a further communications terminal via a radio interface between the mobile station and a base station;

defining, for speeding up the setting up of the traffic relationship, and during a previous physical traffic relationship, at least parts of said context between the mobile station and the base station before the traffic relationship is set up and before clearing down the previous physical traffic relationship.

2. The method as claimed in claim 1, wherein the parts of the traffic relationship context comprise at least one of statements relating to authenticity, encryption, coding and service definition.

3. The method as claimed in claim 1, wherein the context of the traffic relationship is defined by a signaling message interchange.

4. The method as claimed in claim 1, wherein an individual channel of the radio interface is assigned immediately after a traffic relationship request message.

5. The method as claimed in claim 4, wherein the individual channel is one of a fast associated control channel or a wanted data channel.

6. The method as claimed in claim 1, wherein a logic traffic relationship which defines the context of the traffic relationship is set up for data transmission between the mobile station and the base station, physical traffic relationships using radio resources being set up only at times within the logic traffic relationship.

7. The method as claimed in claim 1, wherein at least parts of the context definition remain stored after a clearing of a logic traffic relationship.

8. The method as claimed in claim 3, wherein, when a physical traffic relationship is set up again between the mobile station and the base station within a logic traffic relationship, no further context definition takes place before assignment of an individual channel of the radio interface.

9. The method as claimed in claim 8, wherein, in addition and before clearing down a logic traffic relationship between the mobile station and the base station, a context definition is carried out for a following logic traffic relationship between the mobile station and the further communications terminal.

10. The method as claimed in claim 1, wherein, after transmission of a data packet, a time switch, which can be preset, is reset and is activated, and wherein the physical traffic relationship is cleared down after a set time duration period has elapsed.

11. The method as claimed in claim 1, wherein for the traffic relationship between the mobile station and the base station is determined at periodic intervals and is stored in the mobile station independently of existing traffic relationships.

12. The method as claimed in claim 1, wherein the traffic relationship context is defined by a protocol between the mobile station and further communications terminal.

13. The method as claimed in claim 1, wherein the context of the traffic relationship provides a prioritized assignment of resources of the radio interface for a next information transmission in the traffic relationship.

14. The method as claimed in claim 6, wherein, when a physical traffic relationship is set up again between the mobile station and the base station within a logic traffic relationship, no further context definition takes place before assignment of an individual channel of the radio interface.

15. The method as claimed in claim 14, wherein, in addition and before clearing down a logic traffic relationship between the mobile station and the base station, a context definition is carried out for a following logic traffic relationship between the mobile station and the further communications terminal.

19. The radio station as claimed in claim 14, wherein the radio station further comprises a controller for controlling the defining means such that the context of the traffic relationship is defined by prioritized assignment of resources of the radio interface for a next information transmission.

16. A radio station in a mobile radio network having mobile stations and base stations comprising:

a transmitting device for transmitting information within a traffic relationship via a radio interface between a mobile station and a base station;

a defining device for defining a context, such that, for speeding up a setting of the traffic relationship, during a previous physical traffic relationship, at least parts of said context between the mobile station and the base station are defined before the traffic relationship is set up and before clearing down the previous physical traffic relationship.

17. The radio station as claimed in claim 16, wherein the radio station is one of a mobile station and a base station and transmits packetized data.

18. The radio station as claimed in claim 17, wherein the radio station further comprises a controller for controlling the defining means such that an individual channel of the radio interface for the traffic relationship is assigned immediately after a traffic relationship request message.
