Background technology
It is the access mode on basis that the 3rd third-generation mobile communication system has extensively adopted with CDMA (Code Division Multiple Access, code division multiple access), and its essential characteristic is exactly to distinguish different user terminals with different code words.The employed sign indicating number of TD-SCDMA (Time Division Synchronized Code Division MultipleAccess, time-division synchronization CDMA) system can be divided into by type: downlink frequency pilot code, ascending pilot frequency sign indicating number, cell scrambling, mid-(midamble) sign indicating number and orthogonal variable spreading factor sign indicating number (OVSF).
In the actual networking process of TD-SCDMA system, need in advance the sign indicating number resource is planned, to avoid interference the lifting network performance.
Because the maximum spreading factor that the TD-SCDMA system is supported is 16chip, scrambler length is also shorter simultaneously, only be 16chip, the channel code of TD-SCDMA system like this, promptly just not necessarily has good cross correlation between the compound key that combines by scrambler and ovsf code, in some cases, the situation that compound key between neighbor cell can occur overlapping fully, if the signal strength signal intensity of the user terminal of the different districts of arrival this moment receiver is more approaching, then the signal between user terminal is difficult to be distinguished, can form the multiple access interference like this and cause relevant code track to lose efficacy, thereby cause the loss of capacity.
When carrying out the network planning, code word is to determine according to the scene of setting, and in actual applications, because the continuous variation of scene, definite code word not necessarily can satisfy the demand of current scene, at this moment can increase the interference of minizone.And also do not have at present a kind of scheme that code word is detected.
In sum, owing to can't judge at present whether the code word of configuration is unusual, thus be difficult to know whether the sign indicating number resource of current setting satisfies the demand of current scene.
Summary of the invention
The embodiment of the invention provides a kind of method and apparatus of error detecting code resource, whether reasonable in order to the sign indicating number resource that solves the wireless access network that can't judge configuration that exists in the prior art, thus be difficult to know whether the sign indicating number resource of current setting satisfies the problem of current scene demand.
The method of a kind of error detecting code resource that the embodiment of the invention provides, this method comprises:
Extract the wireless parameter of first sub-district and second sub-district respectively, wherein second sub-district is the adjacent area of first sub-district;

Embodiment
The embodiment of the invention is extracted the wireless parameter of first sub-district and second sub-district respectively, and wherein second sub-district is the adjacent area of first sub-district; According to the wireless parameter and the predefined testing conditions that extract, whether the sign indicating number resource that detects second cell configuration is reasonable.Owing to whether the sign indicating number resource of the wireless access network that can judge configuration is reasonable, thereby whether the sign indicating number resource that can determine current setting satisfies the current scene demand.
Wherein, the scheme of the embodiment of the invention can be applied in the TD-SCDMA system; Also can be applied in other systems that need dispose code word, such as other 3-G (Generation Three mobile communication system) such as WCDMA, CDMA2000.
Below in conjunction with Figure of description the embodiment of the invention is described in further detail.
As shown in Figure 1, the equipment of embodiment of the invention error detecting code resource comprises: extraction module 10 and detection module 20.
Extraction module 10 is used for extracting respectively the wireless parameter of first sub-district and second sub-district, and wherein second sub-district is the adjacent area of first sub-district.
Detection module 20 is used for wireless parameter and predefined testing conditions according to extraction module 10 extractions, and whether the sign indicating number resource that detects second cell configuration is reasonable.
The wireless parameter of sub-district includes but not limited to one or more in the following parameters:
Frequency, code character, scrambler.
Wherein, extraction module 10 can extract parameters all in the wireless parameter; Also the parameter that needs in the wireless parameter can be only extracted,, the scrambler in the wireless parameter can be only extracted such as need the scrambler of sub-district being compared.
In concrete the enforcement, RNC (Radio Network Controller, radio network controller) grasping with base station that this RNC is connected under the configuration (comprising the adjacent area) of all sub-districts, so extraction module 10 can from first sub-district under the RNC that is connected of base station extract wireless parameter.
Need to prove that the embodiment of the invention is not limited to extract wireless parameter from RNC, other modes that can extract wireless parameter all are suitable for the embodiment of the invention.
Testing conditions can be a wireless parameter correlation detection condition.
Wireless parameter correlation detection condition comprises that first sub-district and second sub-district are the alien frequencies adjacent areas.
Accordingly, if first sub-district and second sub-district are the alien frequencies adjacent areas, detection module 20 determines that the sign indicating number resource of second cell configuration is reasonable; If first sub-district and second sub-district are not the alien frequencies adjacent areas, detection module 20 determines that the sign indicating number resource of second cell configuration is unreasonable.
Further, wireless parameter correlation detection condition can also include but not limited to one or more in the following condition:
Scrambler in the wireless parameter of the scrambler in the wireless parameter of first sub-district and second sub-district does not belong to same code character;
The correlation of the code character of the code character of first compound key of first sub-district and second compound key of second sub-district is reasonable.

If first sub-district and second sub-district are not the alien frequencies adjacent areas, in wireless parameter correlation detection condition, be other conditions the alien frequencies adjacent area when all satisfying except that first sub-district and second sub-district, detection module 20 determines that the sign indicating number resource of second cell configuration is reasonable;
If first sub-district and second sub-district are not the alien frequencies adjacent areas, in wireless parameter correlation detection condition, be that detection module 20 determines that the sign indicating number resource of second cell configuration is unreasonable when having one not satisfy in other conditions the alien frequencies adjacent area except that first sub-district and second sub-district.
Each testing conditions under the following mask body introduction.
Condition one, first sub-district and second sub-district are the alien frequencies adjacent areas.
If comprising first sub-district and second sub-district in the wireless parameter correlation detection condition is the alien frequencies adjacent area, then detection module 20 judges according to the wireless parameter of first sub-district and the wireless parameter of second sub-district whether first sub-district and second sub-district are the alien frequencies adjacent areas.
With TD-SCDMA is example, CONTINENTAL AREA OF CHINA has been enabled 2010～2025MHz frequency range at present, the TD-SCDMA carrier spacing is 1.6MHz, totally 9 frequencies, because adopted N frequency point networking (N is the integer more than or equal to 1) at present, as long as relatively two subdistrict frequency points configuration successively is arbitrary carrier frequency configuration consistency, determining it is not the alien frequencies adjacent area, promptly is homogeneous-frequency adjacent-domain.
