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 of mobile stations, comprising:

at least two base stations with antennas for sending and/or receiving communication signals, said communication signals forming radio traffic in said mobile network;

in said at least two base stations each base station covering an area thereby forming a radio cell, each said radio cells being divided into a close-up range and a far range having frequency bands; and

wherein different transmission resources are provided for said radio traffic, and frequency bands of said far range of the two adjacent radio cells are coincident.

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

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

4. A mobile network according to claim 1, wherein wanted and interfering signals occur with an intensity in said mobile network and wherein filter means 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 signal.

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 and interfering signals occur with intensity in said mobile network, and filter means 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 signal.

9. A method for attributing transmission resources in a mobile network for mobile stations for communication, said mobile network comprising at least two base stations with antennas for sending and/or receiving of communication signals, said communication signals forming radio traffic in said mobile network, said at least two base stations each covering an area, said method comprising the steps of:

a) forming at least two radio cells, each of said at least two radio cells resulting from said covered area of said base station with the antennas for sending and/or receiving the communication signals;

b) dividing said radio cells into a close-up range and a far range;

c) attributing different transmission resources to said close-up range and said far range of the radio cell; and

d) attributing coincident transmission resources to said mobile stations for the communication in the far range of two adjacent radio cells.

10. A method according claim 9, wherein frequencies are attributed as said transmission resources.

11. A method according to any of claim 9, wherein time slots are attributed as transmission resources.

12. A method according to claim 9, wherein said mobile network operates according to GSM- and/or UMTS-standard.

13. A method according to claim 12, wherein the transmission sources are provided in the form of frequencies.

14. A method according to claim 12, wherein the transmission sources are provided in the form of time slots.

15. A method according to claim 12, further comprising filter means for removing interfering signals.

16. A method according to claim 15, wherein said filter means is adopted for removing the interfering signals having an intensity corresponding to the intensity of the wanted signal.
