Abstract

A problem with known data transmission networks is that the connection of the terminal equipment to the data transmission network is not flexible. The user must himself actively perform the choice and connection of access as well as it registration with the network nodal point. The invention concerns a method and an arrangement for routing a data transmission connection between terminal equipment and a host over a data transmission network, which network includes at least two access points for connecting the terminal equipment to the data transmission network. The method is characterized in that a least one criterion is established for the choice of access point, the access points are estimated according to said criteria, at least one access point meeting the criteria is chosen, and the data transmission traffic is connected through the chosen at least one access point.

Claims

1. A method for routing a data transmission connection between terminal equipment and a host over a data transmission network, wherein a data transmission network includes at least two access points for connection of the terminal equipment to the data transmission network, the method comprising:

establishing a criterion for a choice of an access point;

evaluating access points according to said criterion;

choosing at least two of the access points which meet said criterion; and

connecting data transmission traffic simultaneously through the at least two chosen access points.

2. Method as claimed in claim 1, further comprising choosing the access points meeting said criterion in the terminal equipment.

3. Method as claimed in claim 1, further comprising choosing the access points meeting said criterion in a gateway exchange.

4. Method as claimed in claim 1, further comprising

establishing the criterion for the choice of a transmission capacity of a data transmission of the chosen at least two access points,

choosing the transmission capacity of each chosen access point according to a result of the evaluation, and

proportioning the data transmission between the chosen access points in relation to the chosen transmission capacities.

5. Method as claimed in claim 1, further comprising evaluating the access points constantly.

6. Method as claimed in claim 1, further comprising evaluating the access points at certain intervals of time.

7. Method as claimed in claim 5, further comprising evaluating the access points by monitoring a quality of the data transmission.

8. Method as claimed in claim 1, further comprising giving reports to an application used in the terminal equipment on characteristics of the chosen access points.

9. Method as claimed in claim 8, further comprising adapting a functioning of the application according to the reported characteristics.

10. Method as claimed in claim 1, further comprising reporting characteristics of the chosen access points to a user.

11. Method as claimed in claim 1, further comprising establishing the criterion from an application to be used.

12. Method as claimed in claim 11, further comprising choosing at least one access point meeting said criterion for the application.

13. Method as claimed in claim 1, wherein said evaluating comprises evaluating the access points, in which the access points comprise at least one wireless access point.

14. A method of routing a data transmission connection between terminal equipment and a host over a data transmission network including at least two access points for connection of the terminal equipment to the data transmission network, the method comprising:

establishing a criterion for a choice of a data transmission relaying capacity of the access points;

estimating the access points in accordance with the criterion;

choosing a relaying capacity of each access point according to results of the estimation; and

proportioning data transmission traffic between the access points in relation to the chosen relaying capacities such that data transmission traffic is sent simultaneously through the at least two access points.

15. Method as claimed in claim 14, further comprising estimating the access points according to a criterion in the terminal equipment.

16. Method as claimed in claim 14, further comprising estimating the access points according to the criterion in a gateway exchange.

17. Method as claimed in claim 14, further comprising estimating the access points continuously.

18. Method as claimed in claim 14, further comprising estimating the access points at certain intervals.

19. Method as claimed in claim 14, further comprising estimating the access points by monitoring a quality of a data transmission.

20. Method as claimed in claim 14, further comprising reporting characteristics of the access points to an application used in the terminal equipment.

21. Method as claimed in claim 20, further comprising adapting an operation of the application in accordance with the reported characteristics.

22. Method as claimed in claim 14, further comprising reporting characteristics of the access points to a user.

23. Method as claimed in claim 14, further comprising establishing the criterion from an application to be used.

24. Method as claimed in claim 14, wherein said estimating comprises estimating the access points, in which the access points comprise at least one wireless access point.

25. An arrangement for routing a data transmission connection between terminal equipment and a host over a data transmission network, wherein the data transmission network includes at least two access points for connecting the terminal equipment to the data transmission network, the arrangement comprising:

a router, located in the terminal equipment, configured to route a data transmission through at least two access points simultaneously.

26. Arrangement as claimed in claim 25, wherein the router is configured_to route the data transmission through the at least two access points, in which at least one of the at least two access points comprises a wireless access point.

27.
