However, the statistical analysis of the downlink load historical data of the communication system base station in the "overload detection method for adaptive load overload threshold" only extracts the "load change information" contained in the historical data, but ignores the "load change information". Trend information”, which will result in low reliability in judging the load status of the communication system and false positives

Embodiment Construction

[0100] In order to enable those skilled in the art to which the present invention belongs to understand the present invention more clearly, detailed descriptions will now be given in conjunction with the accompanying drawings.

[0101] Refer to attached Figure 4 , with Figure 4 It is a flow chart of Embodiment 1 of the load control method in the mobile communication system.

[0102] In step 400, the communication system load overload control device is activated, and the activation time usually includes a fixed activation time and a predetermined activation time period.

[0103] In step 410, a quantity reflecting the load of the communication system is sampled according to a predetermined sampling period.

[0104] The value reflecting the load of the communication system may be the downlink transmit power of the base station of the communication system, or the total uplink broadband receiving power of the base station of the communication system. The uplink broadband total...

Abstract

This invention provides a load control method in the communication system including: fetching the history data of the said communication system, analyse the said history data to get the corresponding load variance trend to be taken as the present time viriance trend of the pretested communication system to decide if the measured parameter of the said system used in overload will be over the predesigned over load threshold, if so, the said system engages in pre-overload process, if not, it operates normally. This invention also provides an overload alarm device based on realizing its load control including: a downstream power sampling device a communication system load trend analysis device and an overload deciding device.

Description

technical field [0001] The invention relates to a communication system, in particular to a load control method of the communication system and a load overload alarm device of the communication system. Background technique [0002] In the mobile communication system, there are many multiple access technologies: such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and Code Division Multiple Access (CDMA). [0003] In the code division multiple access mobile communication system, different users in the same cell realize multiple access through different spreading codes, and the occupied time and frequency overlap. In the design of spreading codes, there are schemes such as M sequence, GOLD sequence and OVSF code. Among them, the OVSF code is an orthogonal sequence. In the actual mobile communication system, some systems are designed as asynchronous systems, even synchronous systems have synchronization errors, and the actual propagation cha...
