Embodiment Construction

[0026] The wireless resource management method disclosed in the present invention aims to manage wireless resources by means of cross-layer optimization technology from the perspective of directly affecting the user's application layer.

[0027] Hereinafter, embodiments of the present invention are specifically described with reference to the drawings.

[0028] figure 1 is a diagram showing an example of a typical Frequency Reuse Factor (FRF).

[0029] Techniques for managing radio resources include various methods such as cell planning, power control, and scheduling, and most purposes of radio resource management are to increase channel capacity of lower layers.

[0030] For example, for community planning, such as figure 1 As shown, a method using a frequency reuse factor (hereinafter referred to as "FRF") is used.

[0031] FRF is a parameter for indicating frequency efficiency in a cellular system, indicating the number of cells into which the entire frequency band is di...

Abstract

The present invention relates to an apparatus and method for managing wireless resources, which can provide a service to improve transmission efficiency when multimedia data is transmitted in a mobile communication system. The wireless resource management apparatus includes a data analysis unit (110) for separating data into a plurality of bit stream layers, which form a layered structure, by analyzing the data according to a predetermined rule, and for detecting amounts of information of respective bit stream layers. A wireless resource allocation unit (130) allocates the bit stream layers to frequency bands based on the amounts of information of the bit stream layers detected by the data analysis unit. The present invention is advantageous in that it can reduce inter-cell interference from the standpoint of an application layer that directly influences users.

Description

technical field [0001] The present invention generally relates to an apparatus and method for managing wireless resources, and more particularly, to an apparatus and method for managing wireless resources capable of improving transmission efficiency when transmitting multimedia data in a mobile communication system. Background technique [0002] Most of the causes of communication performance degradation in a wireless communication technology based on a multi-cell environment can be considered to be inter-cell interference (hereinafter referred to as "ICI"). This is especially serious for users located in the outer part of the cell, and becomes a cause of degraded performance of the entire cell. [0003] In particular, for a multimedia service providing high-capacity data, a technique for mitigating ICI is substantially required due to a sudden drop in channel capacity that can be guaranteed in a border area of ​​a cell. [0004] Therefore, most techniques currently being d...
