Abstract

The invention relates to a mobile network, especially according to that of GSM- and/or UMTS-standards for the communication of mobile stations. The network consists of at least two base stations with antennas for sending and/or receiving communication signals, wherein the covered area of the base stations forms a radio cell which is divided into a close-up range and a far range, wherein different transmission sources are provided for the radio traffic.

Claims

1. A mobile network for communication mobile stations, comprising:

at least two base stations having antennas for sending and receiving communication signals, said communication signals forming a radio traffic in said mobile network,

wherein each of said base stations covering an area thereby forming a radio cell, so as to provide the at least two adjacent radio cells with a border area therebetween, a close-up range and a far range are attributed to each said base station, each said close-up range is attributed to a neighborhood adjacent the respective base station and each said far range extends to said border area,

wherein frequency bands and transmission resources that are attributed to the close-up range of one of said base stations are different from the frequency bands and transmission resources of the close-up ranges of others of said base stations, and

wherein identical coincident frequency bands are attributed to said far ranges of said base stations,

wherein a reuse factor in said far ranges is smaller than the reuse factor in said close-up ranges.

2. A mobile network according to claim 1, wherein said transmission resources comprise arrangement for transmitting said communication signals in a form of modulated frequencies.

3. A mobile network according to claim 1, wherein said transmission resources comprise arrangement for transmitting said communication signals in the form of time slots.

4. A mobile network according to claim 1, wherein wanted signal and interfering signal occur with an intensity in said mobile network and wherein a filter arrangement is provided for removing said interfering signals.

5. A mobile network according to claim 4, wherein said intensity of said interfering signals corresponds to said intensity of said wanted signals.

6. A mobile network according to claim 1, wherein said mobile network operates according to GSM- and/or UMTS-standards.

7. A mobile network as claimed in claim 6, wherein wanted signal and interfering signal occur with intensity in said mobile network, and a filter arrangement is provided in said mobile station for removing said interfering signals.

8. A mobile network according to claim 7, wherein said intensity of said interfering signals corresponds to said intensity of said wanted signals.

9. A mobile network according to claim 1, wherein an inverse frequency superposition is provided in said mobile network and admission of occurring interferences is maximized at the border area between said adjacent radio cells.

10. A mobile network according to claim 1, wherein the reuse factor “

3”

is provided in the close-up ranges and the reuse factor “

1”

is provided in the far ranges.

11. A method for attributing transmission resources in a mobile network for communication between mobile stations, said mobile network comprising at least two base stations with antennas for sending and receiving communication signals, said communication signals forming a radio traffic in said mobile network, each said base station having a predetermined coverage area, said method comprising the steps of:

forming at least two adjacent radio cells with a border area therebetween, each said radio cells resulting from said covered areas of said base stations;

attributing a close-up range and a far range to each said base station, each said close-up range is attributed to a neighborhood adjacent the respective base station and each said far range extends to said border area;

attributing frequency bands and transmission resources to the close-up range of one of said base stations that are different than the frequency bands and transmission resources of the close-up ranges of others of said base stations; and

attributing identical coincident frequency bands and transmission resources for the communication in the far range of said base stations;

wherein a reuse factor in the far ranges is smaller than the reuse factor in the close-up ranges.

12. A method according to claim 11, wherein an inverse frequency superposition is provided in said network, and admission of occurring interferences is maximized at the border area between said adjacent radio cells.

13. A method according to claim 11, wherein the reuse factor “

3”

is provided in the close-up ranges and with the reuse factor “

1”

is provided in the far ranges.

14. A method according claim 11, wherein frequencies are attributed as said transmission resources.

15. A method according to claim 11, wherein time slots are attributed as transmission resources.

16. A method according to claim 11, wherein said mobile network operates according to GSM- and/or UMTS-standard.

17. A method according to claim 16, wherein the transmission resources are provided in the form of frequencies.

18. A method according to claim 16, wherein the transmission resources are provided in the form of time slots.

19. A method according to claim 16, further comprising removing interfering signals via a filtering arrangement.

20. A method according to claim 19, wherein said filter arrangement is adopted for removing the interfering signals having an intensity corresponding to intensity of a wanted signal.
