Embodiment in bright, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, broadly falls into the scope of protection of the invention.
As it is shown in figure 1, be an embodiment of cell outage detection method of the present invention, its concrete processing procedure is as follows:
Step 101, when the community collectively covered by first network and the second network doubtful inefficacy in first network being detected
Time, it is thus achieved that community KPI in first network, and obtain community KPI in the second network.
Wherein, community belongs to first network, and this community is in addition to being covered by first network, also by least one other net
Network is covered, and for convenience of description, other networks covering this community is referred to as the second network.
In the embodiment of the present invention, this community can be first network and the co-sited cell of the second network, and Ji Gai community is belonged to
The base station of first network identical with the site of the base station of the second network that this community is belonged to.
Under normal circumstances, the multiple networks covering the same area have different network formats, i.e. the network system of first network
Formula and the second network of network standard are typically different, and such as, first network is Long Term Evolution (LTE, Long Term
Evolution) network, the second network is CDMA (CDMA, Code Division Multiple Access)
Network.
In the embodiment of the present invention, KPI monitor mode can be passed through, community doubtful inefficacy in first network detected.Example
As, pre-set the doubtful inefficacy numerical range of KPI, when the KPI in the first preset time period is monitored, inspection
Measure KPI when belonging to doubtful inefficacy numerical range, confirm community doubtful inefficacy in first network to be detected.In order in time
Detecting the doubtful inefficacy in community, above-mentioned first preset time period is usually arranged as relatively short period of time, for example, it may be half is little
Time or one hour etc..
When community doubtful inefficacy in first network being detected, it is thus achieved that the KPI in first network of the community, and obtain
Community KPI in the second network, in specifically may is that the acquisition community the second preset time period in first network
KPI, and obtain the KPI in the second preset time period in the second network of community.In order to detect the doubtful mistake in community
After effect, further confirming that whether this community is that the accuracy of failure cells is higher, above-mentioned second preset time period is generally arranged
For the longer time, it can be one day or two days etc..
Wherein, it is thus achieved that during the KPI in the second network of community, should comprise with the community obtained KPI in first network
Parameter identical, such as, when obtaining community KPI in first network, only obtain and access number of times, then, when obtaining
When obtaining community KPI in the second network, the most only obtain and access number of times.
In the embodiment of the present invention, can be according to community cell ID in first network, from this community at the second network
Base station obtains this community KPI in the second network.
Step 102, according to community KPI in first network and community KPI in the second network, confirms that community exists
Whether first network is failure cells.
The KPI of the community owing to being collectively covered by two networks has dependency, i.e. KPI should not have big difference, therefore
The relevance parameter of community KPI in first network and community KPI in the second network, this dependency can be calculated
Parameter can be ratio or difference etc., when relevance parameter is in pre-set interval, community KPI in two networks is described
Relevant, confirm that community is not failure cells in first network；When relevance parameter is not in pre-set interval, illustrate little
KPI in two networks is uncorrelated in district, confirms that community is failure cells in first network.
Additionally, when the KPI in the first network obtained and the second network only comprises a traffic measurement index, such as,
When only comprising telephone traffic, according to judging whether community this traffic measurement index in two networks has dependency, come
Determine whether community KPI in two networks has dependency；KPI in the first network obtained and the second network
When comprising the traffic statistical indicator of more than two, such as, when comprising telephone traffic and access number of times, can be at the KPI obtained
In all traffic measurement indexs of comprising when all there is dependency, determine that community KPI in two networks has dependency.
Therefore, in the cell outage detection method of the embodiment of the present invention, when detecting by first network and the second network
The community collectively covered during doubtful inefficacy, not only to obtain this community KPI in first network in first network, also
Obtain this community KPI in the second network, according to this community KPI in two networks, further confirm that this community
Whether it is failure cells.Owing under normal circumstances, community KPI in two networks has dependency, therefore passing through will

KPI in one network, and obtain community KPI in the second network.
Step 202, it is judged that whether the relevance parameter of community KPI in two networks is in pre-set interval.If judging
Result is yes, then perform step 203；If judged result is no, then perform step 204.
Wherein, above-mentioned relevance parameter can be ratio or difference etc., such as, when relevance parameter is difference, and preset areas
Between when being [0,15], if the KPI obtained in step 201 only comprises access one traffic measurement index of number of times, and community
Access number of times in first network is 0, and community access number of times in the second network is 100, then can calculate community
The relevance parameter of the KPI in first network and community KPI in the second network is 100, such that it is able to judge
This relevance parameter is not in pre-set interval.
Step 203, confirms that community is not failure cells in first network.
Step 204, confirms that community is failure cells in first network.

As, pre-set the doubtful inefficacy numerical range of KPI, within a period of time, detect that KPI belongs to doubtful inefficacy numerical value
During scope, confirm community doubtful inefficacy in first network to be detected.In order to detect the doubtful inefficacy in community in time, above-mentioned
A period of time is set to relatively short period of time, for example, it may be half an hour or one hour etc..
Wherein, it is thus achieved that telephone traffic be the telephone traffic in preset time period, such as, this preset time period is 1 day.
Step 302, it is judged that whether the ratio of community telephone traffic in two networks is in pre-set interval.If judged result
It is yes, then performs step 303；If judged result is no, then perform step 304.
Such as, pre-set interval is [0.5,1], and the community obtained in step 301 telephone traffic in the lte networks is 0, little
District's telephone traffic in the cdma 2000 network is 100 hours, then can calculate community telephone traffic in two networks
Ratio is 0, thus judges that this ratio is not in pre-set interval.
Step 303, confirms that community is not the most failure cells.
Step 304, confirms that community is failure cells in the lte networks.
