Abstract

The present invention relates to a method of selecting a link adaptation parameter for a communication link between a mobile terminal and a network component of a wireless telecommunication network, the method comprising the steps of: providing means for determining of a link adaptation parameter based on a geographic positions of the mobile terminal, determining of a geographic position of the mobile terminal, determining the link adaptation parameter for the communication link based on the geographic position of the mobile terminal.

Claims

1. A method of selecting at least one link adaptation parameter for a communication link between a mobile terminal and a network component of a wireless telecommunication network, the method comprising the steps of:

providing means for determining of a link adaptation parameter based on a geographic positions of the mobile terminal,

determining of a geographic position of the mobile terminal,

determining the link adaptation parameter for the communication link based on the geographic position of the mobile terminal.

2. The method of claim 1, the link adaptation parameter being a modulation and/or coding scheme from a set of modulation and/or coding schemes.

3. The method of claim 1, the means for determining of a link adaptation parameter being provided as a digital map which assigns the link adaptation parameters to geographic positions and/or regions.

4. The method of claim 1, further comprising:

predicting of a future geographic position of the mobile terminal based on geographic positions of the mobile terminal which have been determined previously,

determining a future link adaptation parameter for the predicted geographic position.

5. A method of generating a database for assigning of link adaptation parameters to geographic positions, the method comprising the steps of:

a) receiving of a link quality parameter from a mobile terminal,

b) determining of a geographical position of the mobile terminal,

c) determining of a link adaptation parameter based on the link quality parameter,

d) storing of the link adaptation parameter being assigned to the geographical position,

repeating of steps a) to d) for a number of times.

6. The method of claim 5, whereby the steps a) to d) are repeated during a pre-determined time interval.

7. A computer program product, in particular digital storage medium, for selecting a link adaptation parameter for a communication link between a mobile terminal and a network component of a wireless telecommunication network, comprising program means for performing the steps of:

entering of a geographical position of the mobile terminal,

performing a database query in a database which stores link adaptation parameters being assigned to geographical positions in order to determine the link adaptation parameter of the geographical position of the mobile terminal,

outputting of the link adaptation parameter.

8. A computer program product, in particular digital storage medium, for generating of a database for assigning of link adaptation parameters to geographical positions, comprising program means for performing the steps of:

entering of a geographical position of a mobile terminal,

entering of a link adaptation parameter which has been determined for a communication link between the mobile terminal and a network component of a wireless telecommunication network,

storing of the link adaptation parameter with the assigned geographical position for later retrieval using a geographical position as a key.

9. A network component of the wireless telecommunication network, the network component comprising:

means for entering of a geographical position of a mobile terminal,

means for performing a database query in a database storing link adaptation parameters being assigned to geographical positions using the geographical position of the mobile terminal as a key in order to determine the link adaptation parameter for a communication link to the mobile terminal in the wireless telecommunication network.

10. A telecommunication network for establishing a communication link between a mobile terminal and a network component, the communication link having a link adaptation parameter, the telecommunication network comprising:

database means for storing of link adaptation parameters being assigned to geographical positions,

means for determining of a geographical position of the mobile terminal,

means for determining of the link adaptation parameter for the telecommunication link based on the geographical position by querying the database using the geographical position of the mobile terminal as a key.
