Embodiment Construction

[0035] Functional Overview

[0036]Considering that the indoor and outdoor different-frequency networking mode leads to a decrease in spectrum utilization efficiency, an embodiment of the present invention provides a method and system for networking an indoor and outdoor distribution system. The method includes: when the indoor distribution system needs to use the frequency point of the outdoor distribution system , detect the scene characteristics of the indoor distribution system, and judge whether there is an indoor distribution inner circle area that meets the preset conditions in the indoor distribution system according to the detected scene characteristics; if there is an indoor distribution inner circle area that meets the preset conditions, then the indoor distribution system The system is divided into inner and outer rings.

[0037] Aiming at the problem of low spectrum utilization caused by the different frequency networking of the indoor and outdoor distribution sys...

Abstract

The invention discloses a method and system for networking indoor and outdoor distribution systems. The method comprises the steps of: detecting scene characteristics of an indoor distribution system when deciding that the indoor distribution system needs to use frequency points of an outdoor distribution system, and judging whether the indoor distribution system has an indoor distribution inner ring region meeting preset conditions or not; and further dividing the indoor distribution system into an inner ring and an outer ring if the indoor distribution inner ring region meeting the preset conditions exists. The method and the system solve the problem of low utilization efficiency caused by an indoor and outdoor pilot frequency networking, further improve the frequency spectrum utilization rate, and do not cause serious channel interference.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and system for networking an indoor and outdoor distribution system. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA for short) commercial network adopts N-frequency co-frequency networking, that is, each cell has the same N frequency points, Including 1 main frequency and N-1 auxiliary frequency. Common channels are usually established only on the primary frequency, while dedicated channels carrying services are established on all N frequency points. The main frequency of each cell is usually planned using the principle of different frequency networking to reduce the interference between common channels under the same frequency network, while the same frequency interference between dedicated channels is usually through physical layer technology (such as multi-cell joint detection ) to eliminate or avoid related algorit...
