Problems solved by technology

Hard interference adopts the spectrum suppression interference method, which can only interfere but not control, which will bring problems such as electromagnetic pollution and out-of-band interference
Signaling interference will cause problems such as high power consumption and poor effect when there are too many base stations

Embodiment Construction

[0037] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described below through specific embodiments and accompanying drawings.

[0038] figure 1 The signal format of the physical channel of TD-SCDMA is given. A TDMA frame has a length of 10ms and is divided into two 5ms subframes, and the structures of the two subframes within each 10ms frame length are exactly the same. The parameters in the figure are explained as follows:

[0039] Time slot #n (n from 0 to 6): the nth service time slot, 864 chip duration;

[0040] DwPTS: downlink pilot time slot, 96 chip duration;

[0041] UpPTS: uplink pilot time slot, 160 chip duration;

[0042] GP: Main guard interval of TDD, 96 chip duration.

[0043] Such as figure 1 As shown, the total number of uplink and downlink service time slots is 7, and the length of each service time slot is a duration of 864 chips. Of the 7 traff...

Abstract

The invention discloses a mobile communication system intelligent signal control method and device based on the channel distinguish. The method includes 1, arranging a device body in each cell to be controlled, allowing the device body to acquire downlink timing signals through downlink synchronous signals DL-SYNC emitted in TD-SCDMA system downlink pilot time slots, and performing the synchronization on downlink time slots, sub frames and frames; 2, acquiring downlink codes SYNC_DL from the downlink synchronous signals DL-SYNC; 3, determining the basic Midamble codes used by the cell and corresponded cell scrambling codes according to an SYNC_DL code and TD-SCDMA protocol code relation table, and finishing the downlink synchronous locking; 4, generating a downlink public channel of the cell according to the SYNC_DL codes, the basic Midamble codes and the scrambling codes, and emitting and covering the cell. The method can be applied to intelligent and environment-friendly control of mobile 3G frequency bands.

Description

technical field [0001] The invention belongs to the technical field of mobile communication 3G, and in particular relates to a method for controlling intelligent signals in a time division multiple access mobile communication system based on channel differentiation, and an intelligent signal controlling device for the mobile communication system using the method. Background technique [0002] In modern society, mobile phones have increasingly become an indispensable and important tool in people's work and life. It is self-evident that the widespread use of mobile phones brings convenience in communication, but at the same time it also creates many hidden dangers that cannot be ignored. How to effectively prevent the abuse of mobile phones in meetings and ensure the normal order of the society has become an urgent problem to be solved, especially for the current technologically advanced 3G system. [0003] TD-SCDMA, as the third generation mobile communication standard (refe...
