Abstract

A scheduler for a cellular telecommunications network is provided having a first base station corresponding to a first cell and serving a cell area, the scheduler being adapted to: identify mobile devices located at the edge of the cell area; obtain resource usage information of mobile devices located at the edge of neighbouring cell areas; and, allocate resource blocks for data transmission based on the location of the mobile devices and the received resource usage information, wherein those data transmissions with a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area. An associated method and computer readable storage medium are also provided.

Claims

1. A scheduler for a cellular telecommunications network having a first base station corresponding to a first cell and serving a cell area, the scheduler being adapted to:

identify mobile devices located at the edge of the cell area;

obtain resource usage information of mobile devices located at the edge of neighbouring cell areas; and

,

allocate resource blocks for data transmissions based on the location of the mobile devices and the received resource usage information,

wherein those data transmissions with a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area.

2. A scheduler according to claim 1, wherein those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area are allocated with a higher priority than those data transmissions without a high priority indication and which are for mobile devices located at the edge of the cell area.

3. A scheduler according to claim 2, wherein those data transmissions without a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions without a high priority indication and which are for mobile devices not located at the edge of the cell area.

4. A scheduler according to claim 1, wherein the high priority indication is a guaranteed bit rate, GBR.

5. A scheduler according to any claim 1, wherein the resource blocks are allocated using enhanced proportional fair scheduling.

6. A scheduler according to claim 1, wherein the resource usage information comprises a High Interference Indicator and an Overload Indicator in the uplink direction and a Relative Narrowband Transmit Power in the downlink direction.

7. A method in a cellular telecommunications network for allocating resource blocks for data transmission to or from mobile devices connected to a first base station, the first base station corresponding to a first cell and serving a cell area, the method comprising:

identifying mobile devices located at the edge of the cell area;

obtaining resource usage information of mobile devices located at the edge of neighbouring cell areas; and

,

allocating resource blocks for data transmission based on the location of the mobile devices and the received resource usage information,

wherein those data transmissions with a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area.

8. A method according to claim 7, wherein those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area are allocated with a higher priority than those data transmissions without a high priority indication and which are for mobile devices located at the edge of the cell area.

9. A method according to claim 8, wherein those data transmissions without a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions without a high priority indication and which are for mobile devices not located at the edge of the cell area.

10. A method according to claim 7, wherein the high priority indication is a guaranteed bit rate, GBR.

11. A method according to claim 7, wherein the resource blocks are allocated using enhanced proportional fair scheduling.

12. A method according to claim 7, wherein the resource usage information comprises a High Interference Indicator and an Overload Indicator in the uplink direction and a Relative Narrowband Transmit Power in the downlink direction.

13. A computer-readable storage medium having stored thereon instructions which can be executed to perform the method of:

identifying mobile devices located at the edge of the cell area;

obtaining resource usage information of mobile devices located at the edge of neighbouring cell areas; and

,

allocating resource blocks for data transmission based on the location of the mobile devices and the received resource usage information,

wherein those data transmissions with a high priority indication and which are for mobile devices located at the edge of the cell area are allocated with a higher priority than those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area.

14. A computer-readable storage medium as claimed in claim 13 being further configured, for those data transmissions with a high priority indication and which are for mobile devices not located at the edge of the cell area, to allocate those data transmissions with a higher priority than those data transmissions without a high priority indication but which are for mobile devices located at the edge of the cell area.

15. A computer-readable storage medium as claimed in claim 13, being further configured, for those data transmissions without a high priority indication and which are for mobile devices located at the edge of the cell area, to allocate those data transmissions with a higher priority than those data transmissions without a high priority indication but which are for mobile devices not located at the edge of the cell area.

16. A computer-readable storage medium as claimed in claim 13, wherein the high priority indication is a guaranteed bit rate, GBR.

17. A computer-readable storage medium as claimed in claim 13, wherein the resource blocks are allocated using enhanced proportional fair scheduling.

18. A computer-readable storage medium as claimed in claim 13, wherein the resource usage information comprises a High Interference Indicator and an Overload Indicator in the uplink direction and a Relative Narrowband Transmit Power in the downlink direction.
