Abstract

A communication resource allocation method for solving resource request imbalance content in a cell is provided. Considering a propagation environment, the base station allocates a whispering resource to a whispering area, the whispering resource being one part of the communication resource and the whispering area being a peripheral area of the first base station, and allocates a speaking resource to a speaking area, the speaking resource being other parts of the communication resource and the speaking area being a border area of a cell. When the resource request of the whispering area is increased, the base station further allocates a part of the speaking resource to the whispering area or increases a ratio of the whispering resource. When the resource request of the speaking area is increased, the base station controls a threshold value for identifying the whispering and speaking areas or increases a ratio of the speaking resource.

Claims

1. A communication resource allocation method in which a base station allocates a communication resource, comprising:

allocating a whispering resource to a whispering area, the whispering area being a peripheral area of the base station and the whispering resource having a resource area changed within the communication resource with a lapse of time; and

allocating a plurality of speaking resources to a plurality of speaking areas, respectively,

wherein the plurality of speaking areas belong to the base station,

wherein the plurality of speaking areas correspond to a plurality of neighboring base stations, respectively,

wherein each of the plurality of speaking areas is a border area between the base station and a corresponding neighboring base station,

wherein each of the plurality of speaking resources corresponds to a whispering resource of a corresponding neighboring base station,

wherein the plurality of whispering resources have a resource area changed within the communication resource with the lapse of time,

where the communication resource allocation method further comprises obtaining a path loss difference value, the path loss difference value being a difference between first and second path loss values which are respectively given between the base station and a terminal and between one neighboring base station and the terminal;

determining the terminal-including area as the whispering area when the path loss difference value is greater than a predetermined threshold value; and

determining the terminal-including area as a speaking area corresponding to the one neighboring base station when the path loss difference value is less than the predetermined threshold value.

2. The communication resource allocation method of claim 1, wherein obtaining the path loss difference value comprises

receiving the first and second path loss values from the terminal, and

calculating the path loss difference value which is the difference between the first and second path loss values.

3. The communication resource allocation method of claim 1, wherein obtaining the path loss difference value comprises receiving the path loss difference value from the terminal.

4. A communication resource allocation method in which a base station allocates a communication resource, comprising:

allocating a whispering resource to a whispering area, the whispering area being a peripheral area of the base station and the whispering resource having a resource area changed within the communication resource with a lapse of time; and

allocating a plurality of speaking resources to a plurality of speaking areas, respectively,

wherein the plurality of speaking areas belong to the base station,

wherein the plurality of speaking areas correspond to a plurality of neighboring base stations, respectively,

wherein each of the plurality of speaking areas is a border area between the base station and a corresponding neighboring base station,

wherein each of the plurality of speaking resources corresponds to a whispering resource of a corresponding neighboring base station,

wherein the plurality of whispering resources have a resource area changed within the communication resource with the lapse of time,

wherein the communication resource allocation method further comprises;

obtaining a path loss value between the base station and a terminal;

determining the terminal-including area as the whispering area when the path loss value is less than a predetermined threshold value; and

determining the terminal-including area as a speaking area when the path loss value is greater than the predetermined threshold value.

5. A communication resource allocation method in which a base station allocates a communication resource, comprising:

allocating a whispering resource to a whispering area, the whispering area being a peripheral area of the base station and the whispering resource having a resource area changed within the communication resource with a lapse of time; and

allocating a plurality of speaking resources to a plurality of speaking areas, respectively,

wherein the plurality of speaking areas belong to the base station,

wherein the plurality of speaking areas correspond to a plurality of neighboring base stations, respectively,

wherein each of the plurality of speaking areas is a border area between the base station and a corresponding neighboring base station,

wherein each of the plurality of speaking resources corresponds to a whispering resource of a corresponding neighboring base station,

wherein the plurality of whispering resources have a resource area changed within the communication resource with the lapse of time,

wherein the communication resource allocation method further comprises

obtaining a path loss value between one neighboring base station and a terminal;

determining the terminal-including area as the whispering area when the path loss value is greater than a predetermined threshold value; and

determining the terminal-including area as a speaking area corresponding to the one neighboring base station when the path loss value is less than the predetermined threshold value.
