Description
Technical field
The present invention relates to wireless communication system, particularly data feedback channel situation and unusual analytical technology.
Background technology
The three big main flow air interface standard of 3G are determined in 2000 by International Telecommunications Union's (InternationalTelecommunications Union is called for short " ITU ").They are:
Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access is called for short " WCDMA ");
CDMA 2000 (Code Division Multiple Access 2000 is called for short " CDMA2000 ");
TD SDMA (Time Division Synchronous Code Division MultipleAccess is called for short " TD-SCDMA ").
Wherein, WCDMA adopts direct sequence spread spectrum (Direct Sequence Spread Spectrum, abbreviation " DSSS ") CDMA (code division multiple access) system of technology, it expands to user bandwidth more than 1000 times by spreading code, expands channel width to 5MHz.According to information-theoretical theory, can under the situation of low signal-to-noise ratio very, transmit information reliably like this with same transmission rate, strengthen antijamming capability greatly, realized code division multiple access, can support various user data rate.
What deserves to be mentioned is that WCDMA is the third generation wireless communication system that puts it into commercial operation the earliest in the world.
The WCDMA system is by core net (Core Net, abbreviation " CN "), universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network, be called for short " UTRAN ") and subscriber equipment (User Equipment, be called for short " UE ") form, and UTRAN follows the principle of as far as possible separating with the CN function, more particularly, the management function of Radio Resource is concentrated on UTRAN finish, then carry out at CN with professional and application related functions.
This shows that UTRAN is bridge and the tie that connects UE and CN.
In UTRAN, base station uplink receiving channel, hereafter " data feedback channel " is its important part.It is made up of antenna-feedback system and base station two parts.Wherein, antenna-feedback system is meant from antenna to the equipment the base station radio-frequency input.
The antenna opening signal bandwidth internal power that the base station data feedback channel receives is called total received power in broadband (Received Total Wideband Power is called for short " RTWP ").The value of measure R TWP is responsible in the base station, and to the wireless network controller reporting of being responsible for control and management UTRAN network and wireless channel.Generally speaking, the value of RTWP not only depends on the intensity of received signal itself, also is subjected to the influence of numerous factors such as antenna and inside of base station upstream channel gain.
Be to reduce the influence of rapid fading to radio communication, the method that space diversity can be adopted in the base station receives signal from portable terminal respectively with master, diversity antenna.The RTWP value of the main collection of mentioning hereinafter and the RTWP value of diversity, the RTWP value that refers to respectively that above-mentioned master, diversity antenna receive from the set of signals of portable terminal.
The receiver of base station is handled the signal that master, diversity passage receive respectively, generally takes maximum likelihood method.The effect of this master, diversity reception is guaranteed by the irrelevance that master, diversity antenna receive.So-called irrelevance is meant, the signal that main collection antenna receives and the received signal of diversity antenna do not have the characteristic of decay simultaneously, spacing when this also just requires to adopt space diversity between master, the diversity antenna (requires antenna distance greater than 4 meters for GSM 900M greater than 10 times wireless signal wavelength, 1800M requires antenna distance greater than 2 meters), perhaps adopt the way of polarization diversity to guarantee that signal main, that diversity antenna receives does not have identical attenuation characteristic.
Fig. 1 is illustrated in the WCDMA system, portable terminal 101 transmit eat dishes without rice or wine and NodeB in processing procedure.At first, transmitting through barrier 102 reflections of portable terminal 101 forms multipath, received by the antenna 103 of NodeB; Then, received signal is input to baseband processing module 105 after handling through radio-frequency module 104; Then, received signal is transported to radio network controller (Radio Network Controller is called for short " RNC ") 106 by Iub interface after handling through demodulation, the decoding of base band.

For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 2, at first,, detect the RTWP value of main collection and the RTWP value of diversity in step 201.This step can realize that in the present embodiment, this module is arranged in the radio frequency processing module by a RTWP detection module.Be understandable that the RTWP detection module also can independently be provided with.
After this, enter step 202, detect and calculate the multipath energy and the accumulated value thereof of main collection and diversity respectively, and the multipath energy accumulated value of the multipath energy accumulated value of main collection and diversity is poor.This step can realize that in the present embodiment, this module is arranged in the baseband processing module by a multipath energy detection module.Be appreciated that equally above-mentioned multipath energy detection module also can be provided with separately, or be arranged in other existing module.
It is to be noted, though obtain the RTWP value of main collection and the RTWP value of diversity in the present embodiment earlier, obtain the multipath energy and the accumulated value thereof of main collection and diversity again, and the multipath energy accumulated value of the multipath energy accumulated value of main collection and diversity is poor, but the order of two steps can be changed, and does not influence effect of the present invention.
After this enter step 203,, judge whether to satisfy the unusual Rule of judgment of data feedback channel that sets in advance according to the value of obtaining.
Specifically, in the unusual Rule of judgment of data feedback channel of the present invention, if the RTWP value of main collection is less than predetermined first thresholding, or the RTWP value of diversity is less than predetermined second thresholding, the difference of the RTWP value of perhaps main collection and the RTWP value of diversity judges that then data feedback channel is unusual when being scheduled to the 3rd thresholding, so when satisfying above-mentioned Rule of judgment, enter step 204, the reporting uplink channel abnormal.
In addition, in the data feedback channel Rule of judgment, when the difference of the multipath energy accumulated value of described main collection and the multipath energy accumulated value of diversity is higher than the 4th thresholding, judge that also data feedback channel is unusual, so satisfy this condition, also the reporting uplink channel abnormal.
More particularly, also detailed basis for estimation has been proposed for the judgement of data feedback channel abnormal cause in the present invention.In general, the unusual reason of data feedback channel is divided into external interference, diversity reception channel failure and main collection receive path fault.
In the present invention, if meet the following conditions, then the reason that system is unusual with data feedback channel is judged to be main collection receive path fault:
The RTWP value of main collection is during less than first thresholding, or
The difference of the RTWP value of main collection and the RTWP value of diversity is greater than the 3rd thresholding, and the RTWP value of diversity is greater than the RTWP value of main collection, and the difference of main collection multipath energy accumulated value and diversity multipath energy accumulated value is greater than the 4th thresholding, and when the master collects the multipath energy accumulated value less than diversity multipath energy accumulated value, or
The RTWP value of main collection is no abnormal with the RTWP value of diversity, and the main difference that collects multipath energy accumulated value and diversity multipath energy accumulated value is greater than the 4th thresholding, and the master collects the multipath energy accumulated value less than diversity multipath energy accumulated value.
If meet the following conditions, then the reason that system is unusual with data feedback channel is judged to be the diversity reception channel failure:
The RTWP value of diversity is less than second thresholding, or
The difference of the RTWP value of main collection and the RTWP value of diversity is greater than the 3rd thresholding, and the RTWP value of main collection is greater than the RTWP value of diversity, and the difference of main collection multipath energy accumulated value and diversity multipath energy accumulated value is greater than the 4th thresholding, and diversity multipath energy accumulated value is less than main collection multipath energy accumulated value, or
The RTWP value of main collection is no abnormal with the RTWP value of diversity, and the main difference that collects multipath energy accumulated value and diversity multipath energy accumulated value is greater than the 4th thresholding, and diversity multipath energy accumulated value collects the multipath energy accumulated value less than the master.
If meet the following conditions, then the reason that system is unusual with data feedback channel is judged to be external interference.
The difference of the RTWP value of main collection and the RTWP value of diversity is greater than the 3rd thresholding, and the RTWP value of main collection is greater than the RTWP value of diversity, and the master collects the difference of multipath energy accumulated value and diversity multipath energy accumulated value greater than the 4th thresholding, and leads collection multipath energy accumulated value less than diversity multipath energy accumulated value, or
The difference of the RTWP value of main collection and the RTWP value of diversity is greater than the 3rd thresholding, and the RTWP value of diversity is greater than the RTWP value of main collection, and the difference of main collection multipath energy accumulated value and diversity multipath energy accumulated value is greater than the 4th thresholding, and diversity multipath energy accumulated value is less than main collection multipath energy accumulated value.
Pass through the foregoing description, adopt RTWP, and the multipath energy that obtains in the Base-Band Processing adds up and carries out the associating condition detection and the analysis mechanisms of data feedback channel, and the concrete criterion that adopts the multipath energy of using in RTWP and the Base-Band Processing to add up and unite the abnormal cause check and analysis proposed, realized the data feedback channel situation in the WCDMA system and the detection and the analysis of abnormal cause effectively, thereby strengthened the analyzing of base station with maintainable.
More than described according to the unusual analytical method of data feedback channel in the WCDMA system of the first embodiment of the present invention, next described the unusual analytical system of data feedback channel in the WCDMA system according to a second embodiment of the present invention.

The RTWP detection module detects the RTWP value of main collection and the RTWP value of diversity, and detected value is sent to decision logic module 306.Identical with first embodiment, this RTWP detection module can also can be provided with separately as being arranged in the radio frequency processing module 304 as the present embodiment.
The multipath energy detection module detects and calculates the multipath energy and the accumulated value thereof of main collection and diversity respectively, and the multipath energy accumulated value of the multipath energy accumulated value of main collection and diversity is poor, and the result is sent to decision logic processing module 306.Though in the present embodiment module is arranged in the baseband processing module 305, in other embodiments of the invention, this module independently is provided with, perhaps be arranged in the decision logic processing module 306, do not influence effect of the present invention.
Decision logic processing module 306 judges according to the unusual Rule of judgment of predefined data feedback channel according to the value that receives, when satisfying this condition, and reporting uplink channel abnormal then.
Specifically, decision logic processing module 306 is the RTWP value and predetermined first thresholding of relatively more main collection respectively, the RTWP value of diversity and predetermined second thresholding, and the difference of the RTWP value of the RTWP value of main collection and diversity and predetermined the 3rd thresholding, when the RTWP value of described main collection less than predetermined first thresholding, or the RTWP value of diversity is less than predetermined second thresholding, and perhaps the difference of the RTWP value of the RTWP value of main collection and diversity is when being scheduled to the 3rd thresholding
Then decision logic processing module 306 reports unusually.
In addition, the multipath energy accumulated value of the also more described main collection of decision logic processing module 306 and the multipath energy accumulated value of diversity poor, with predetermined the 4th thresholding, when the difference of the multipath energy accumulated value of the multipath energy accumulated value of described main collection and diversity is higher than the 4th thresholding, also satisfy the unusual Rule of judgment of data feedback channel, so decision logic processing module 306 is also with the reporting uplink channel abnormal.
In the present embodiment, also further the unusual analysis of causes provides detailed standard to data feedback channel, and described reason is divided into main collection receive path fault, diversity reception channel failure and external interference.The basic conformance to standard with first embodiment of this standard.In order to make this standard clear more understandable, can be referring to table 1.
