Abstract

A method of allocating a radio resource for a traffic burst is disclosed. The method includes the steps of selecting at least one cell having a pilot signal strength that is greater than a pilot signal strength of a primary cell, requesting a communication resource reservation to the selected cells, receiving results of reservation performed according to the reservation request from the selected cells, and requesting allocation of the communication resource to the cells that secure a maximum data rate by analyzing the results of reservation.

Claims

1. A method of allocating a radio resource comprising the steps of:

selecting at least one cell having a pilot signal strength that is greater than a pilot signal strength of a primary cell;

requesting a communication resource reservation to the selected cells;

receiving results of reservation performed according to the reservation request from the selected cells; and

requesting allocation of the communication resource to the cells that secure a maximum data rate by analyzing the results of reservation.

2. The method as claimed in claim 1, further comprising the steps of:

judging if the number of the cells that secure the maximum data rate is plural; and

if it is judged that the number of the cells is plural, requesting the allocation of the communication resource to the cell having a greatest pilot signal strength among the cells.

3. The method as claimed in claim 1, wherein at the step of requesting the communication resource reservation, the communication resource reservation is requested along with a desired data rate.

4. The method as claimed in claim 1, wherein the step of receiving the results of reservation comprises the steps of:

reserving the radio resource corresponding to a supportable data rate according to the request for the communication resource reservation; and

reporting a result of reservation.

5. The method as claimed in claim 1, wherein a threshold value of the pilot signal strength of the primary cell is a value that is changed according to a communication environment.

6. The method as claimed in claim 1, wherein the data is packet data.

7. The method as claimed in claim 6, wherein the data is packet data transmitted through a supplemental channel.

8. The method as claimed in claim 1, further comprising the step of determining a traffic connection with the cells whose traffic connection is not determined among the cells selected at the step of requesting the resource reservation.

9. A method of allocating a radio resource in a communication system including a plurality of mobile stations and at least one base station that performs a radio connection of the mobile stations, the method comprising the steps of:

having data to be newly transmitted selecting at least one target base station having a pilot signal strength that is greater than a reference pilot signal strength at a source base station;

requesting a communication resource reservation to the selected target base stations through a burst request message at the source base station;

reserving the communication resource according to the reservation request, and reporting results of reservation to the source base station as a response message to the burst request message at the target base stations; and

analyzing the results of reservation, and requesting allocation of the communication resource to the target base stations that secure a maximum data rate through a burst commit message at the source base station.

10. The method as claimed in claim 9, wherein the step of requesting the allocation of the resource comprises the steps of:

selecting the target base station having a greatest pilot signal among the plurality of target base stations that secure the maximum data rate at the source base station; and

requesting the allocation of the communication resource to the selected target base station at the source base station.

11. The method as claimed in claim 9, wherein at the step of requesting the communication resource reservation, the communication resource reservation is requested along with a desired data rate.

12. The method as claimed in claim 9, further comprising the steps of:

allocating he communication resource according to the allocation request at the target base station; and

reporting a result of the communication resource allocation to the source base station.

13. The method as claimed in claim 9, wherein the reporting step comprises the steps of:

reserving the radio resource corresponding to a supportable data rate according to the request for the communication resource reservation at the target base station; and

reporting a result of the radio resource reservation to the source base station.

14. The method as claimed in claim 9, wherein a threshold value of the pilot signal strength is a value that is changed according to a communication environment.

15. The method as claimed in claim 9, wherein the data is packet data.

16. The method as claimed in claim 9, wherein the data is packet data transmitted through a supplemental channel.

17. The method as claimed in claim 9, further comprising the step of determining a traffic connection with the cells whose traffic connection is not determined among the cells selected at the step of requesting the resource reservation.
