Abstract
The invention relates to an uplink fault warning module on repeater station which can be used in such systems as GSM, CDMA, WCDMA and TD-SCDMA and a fault warning method. The uplink fault warning module on repeater station comprises an uplink signal source module which switches in an uplink coupling aperture of repeating terminal diplexer; the uplink signal source module provides a fixed analogue signal emitting source for the uplink and reports whether the module is normal to a monitoring unit module; an uplink signal collection module which is connected with an uplink power amplifier outputting terminal from which the uplink signal collection module collects the uplink power for the use of an uplink fault analysis module; the uplink fault analysis module detects the uplink outputting power through the uplink signal source which is open in a fixed time and the uplink signal collection module, makes analysis, decides whether the uplink works normally in such a way and reports the result to the monitoring unit module. The uplink fault warning module on repeater station can reflects the state of the uplink timely and truly.
Description
Technical field
The present invention relates to can be applicable to direct end uplink link failure alarm module and fault alarming method in GSM, CDMA, WCDMA, the TD-SCDMA system.
Background technology
Referring to Fig. 1, the used up fault detection technique in repeater has following several at present:
A, up LNA module alarm failure;
B, up power amplifier module fault warning;
C, up other module alarm failure;
If top a certain alarm occurs then is judged to uplink failure alarming.In most of the cases upward signal power is lower owing to the repeater, and if do not have the cellphone subscriber to make a phone call then have only the end to make an uproar, so be difficult to whether normally carry out fault judgement with signal power.Therefore, nearly all be to adopt same technology to the detection of fault in these modules, as to detections such as electric current, voltage, temperature, if promptly these electric parameters occur unusually then are judged to fault.Yet electric parameter can change along with the variation of environment for use, and the aging of components and parts also can influence the electric parameter value simultaneously, so so detection method usually causes the mistake alarm and leaks alarm taking place frequently:
The mistake alarm: radio frequency link normal (cellphone subscriber's energy normal power-up words), however up fault warning is quoted in the repeater;
Leak alarm: radio frequency link undesired (cellphone subscriber can not normal power-up words), however that the repeater is still reflected is up normal.
Summary of the invention
First purpose of the present invention provides a kind of direct end uplink link failure alarm module that can in time, truly reflect uplink conditions.
Another object of the present invention provides a kind of fault alarming method that can in time, truly reflect uplink conditions
For realizing above-mentioned first purpose, the invention provides following technical scheme:
Direct end uplink link failure alarm module comprises:
The upward signal source module, it inserts the up coupling aperture of retransmitting the end duplexer; Whether the upward signal source module provides a fixing analog signal emission source for up link, and report this module normal to the monitoring unit module;
Uplink signal collection module, it connects up power amplifier output, and the size that uplink signal collection module is gathered ascending power from up power amplifier output is used for following up failure analysis module;
Up failure analysis module, its upward signal source by regularly opening, and by described uplink signal collection module up power output is detected, and analyzed, whether working properly, and offer the monitoring unit module if drawing up link.
For realizing above-mentioned second purpose, the invention provides following technical scheme:
The method that adopts above-mentioned direct end uplink link failure alarm module to carry out fault warning, it comprises following process:
A) direct end uplink link failure alarm module is packed into repeater;
B) generally speaking, up failure analysis module is regularly opened the upward signal source; When the up link alarm module produced abnormality alarming, up failure analysis module was then opened the upward signal source immediately;
C) up failure analysis module detects uplink signal strength, quality or gain by uplink signal collection module, thereby judges whether up link is working properly;
D) whether working properly up failure analysis module draw up link result, newspaper and monitoring unit module.
Said method can thoroughly solve the mistake alarm of direct end uplink fault and leak the problem of alarm, and when up radio frequency link normal (cellphone subscriber can normal power-up words), the repeater be quoted up normal; As up radio frequency link undesired (cellphone subscriber can not normal power-up words), up fault warning be quoted in the repeater.
Above-mentioned direct end uplink link failure alarm module possesses following function:
1, self-timing produces up analog signal, but not interference handset signal and base station;
2, detect uplink gain, signal power, signal quality etc. automatically, with the situation of true reflection up link;
3, all detection techniques before compatible, and with serve as with reference to reference, guarantee in time, truly to reflect uplink conditions.
Description of drawings
Fig. 1 has the direct end uplink system block diagram now;
Fig. 2 is the direct end uplink system block diagram that contains direct end uplink link failure alarm module of the present invention.
The invention will be further described below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 1, direct end uplink link failure alarm module comprises upward signal source module, uplink signal collection module and up failure analysis module.
The upward signal source module inserts the up coupling aperture of retransmitting the end duplexer.Whether the upward signal source module provides a fixing analog signal emission source for up link, and report this module normal to the monitoring unit module.The switch of control analog signal emission is controlled in the upward signal source module, and frequency can be established.Described switch is a normally closed switch, and this switch is regularly opened, and the regular time can be thought setting, such as being set at 24 hours, keeps 1～2 second after each the unlatching.The frequency of upward signal source module institute launching simulation signal is traditionally arranged to be the edge frequency, like this interference base station not.
Uplink signal collection module connects up power amplifier (PA) output, and the size that uplink signal collection module is gathered ascending power from up power amplifier output is kept supplying capable failure analysis module and used.
The upward signal source of up failure analysis module by regularly opening, and by described uplink signal collection module up power output is detected, and analyzed, whether working properly, and offer the monitoring unit module if drawing up link.
The method that adopts above-mentioned direct end uplink link failure alarm module to carry out fault warning comprises following process:
A) direct end uplink link failure alarm module is packed into repeater; The upward signal source module inserts the up coupling aperture of retransmitting the end duplexer, and uplink signal collection module connects up power amplifier output.
B) generally speaking, up failure analysis module regularly (as per 24 hours once, and kept 1～2 second) open the upward signal source; In particular cases, when for example having uplink module to produce abnormality alarming, up failure analysis module is then opened the upward signal source immediately;
C) up failure analysis module detects uplink signal strength, quality or gain by uplink signal collection module, thereby judges whether up link is working properly;
