Embodiment Construction

[0021] Accompanying drawing discloses principle block diagram of the present invention, below in conjunction with accompanying drawing the present invention is described further, by Fig. 1 as seen:

[0022] It includes a low noise amplifier 1, a radio frequency filter 2, a mixer 3, an intermediate frequency filter (bandwidth 200khz) 4, an amplifier 5, a detector 6, a comparator 7, a local oscillator 8, and a single chip microcomputer 9. The signal generated by comparing the envelope of the analog signal output by the detector with the set level is input to the single chip microcomputer. The single-chip microcomputer counts the number of pulses input for a period of time (number of frequency hopping * one frame time), which is the number of users of all frequency hopping frequency points in one frame time of the cell. The frequency point of the local oscillator can be set by the single-chip microcomputer to select any one of all frequency hopping frequency points in the detecti...

Abstract

Based on signal of one GSM frame lasts out eight pieces of time slot, thus, when making online comm, one user uses one time slot. If there is no online user, then the time slot has no signal. Analog signal represents generated pulse envelope. Pulse generated from analog signal is input to singlechip. Based on feature of the signal, the method obtains how many users communicate online in one GSM frame. In GSM hopping frequency sector, user operates at different frequency points (FP). In single FP, making statistics for hopping frequency number * n time in a period of time, the method obtains quantity of user in time of n frame for all FPs in a sector. Converting signal in RF carrier to IF signal, the method detects quantity of user carried by the carrier wave in the frame after following processes including amplification in low noise, RF sound surface filtering, IF amplification, demodulation etc on inputted RF signal by monitoring module for service of each carrier wave.

Description

technical field [0001] The invention relates to the field of GSM mobile communication, in particular to a method and a device for counting frequency-hopping GSM cell users. Background technique [0002] In the past, BSC equipment was mainly used to count the number of users in frequency-hopping GSM cells. This method requires baseband demodulation, which is very complicated. It is difficult for some equipment manufacturers to optimize the wireless network, and the cost is very high. Now many GSM cells implement the frequency hopping function, which makes it difficult to use wireless equipment to count the number of users. [0003] There will be some problems during the operation of the mobile network. Many companies have proposed some solutions during the network optimization process. For example, CN03801318.5 of Panasonic Electric invented a new base station device and sector control method to increase the system line capacity. This method involves the modification of the...
