Embodiment
The embodiment of the present application solves prior art by providing a kind of abnormal method of detection RRU links and a kind of RRU
In for RRU links, whether failure judges not accurate enough technical problem.It is effectively guaranteed and is accurately judged to RRU links and is
No failure.
Technical scheme in the embodiment of the present application is to solve the above problems, general thought is as follows：
Initial parameter information, such as at least one of gateway information or IP information are preserved in RRU in advance, may be used also certainly
With including other information, such as RRUID.
Then at certain moment, if RRU will detect whether its link breaks down, of the RRU now is just first obtained
One parameter information, first parameter information is identical with the parameter information included in initial parameter information, such as, if original ginseng
Gateway information is included in number information, then the first parameter information also includes gateway information.
Then, by the first parameter information and initial parameter information matches, if the match is successful for energy, RRU link is shown
Do not break down, and if matching is unsuccessful, then it represents that RRU link breaks down.
In order to be better understood from above-mentioned technical proposal, below in conjunction with Figure of description and specific embodiment to upper
Technical scheme is stated to be described in detail.
Embodiment one
The embodiment of the present application one provides a kind of detection RRU links abnormal method, as shown in Fig. 2 methods described includes
Following steps：
S201：RRU M the first parameter informations are obtained, wherein, each first parameter information is believed including at least gateway
Breath or IP information, M are the integer more than or equal to 1；
In specific implementation process, the acquisition M the first parameter informations, as shown in figure 3, following process can be included：
S301:Every prefixed time interval, a broadcast message is sent；
S302：Obtain a BBU and M extremely the first parameter informations are sent based on the broadcast message.
Because RRU is after operation, in this case it is not apparent that the IP address of itself, also do not know the information for the BBU being attached thereto, than
Such as：Assuming that RRU IP information is：200.254.0.8, its original BBU IP is：200.254.3.16 if at certain
At one moment, the RRU is extracted from original BBU, insert the BBU that an ID is 200.254.4.16.Now, RRU and do not know
Road BBU replacing information, if hair common message obtains the first parameter information, can only be to IP：200.254.3.16
BBU baseband board sends information, but because actually BBU IP is modified, so the RRU be do not receive it is any
BBU response messages, and in the case where not receiving response message, the RRU can be sent always to BBU baseband board please
Ask, one, cause the wasting of resources；Two, also cause link obstructions, so as to chain rupture occur.
In order to solve the above problems, so generally, RRU is sent wide using the form of broadcast to BBU baseband board
Information is broadcast to obtain first parameter information, wherein, comprising information such as RRUID in the broadcast message, so, even if BBU
IP change, after also being changed BBU (such as：IP is 200.254.4.16 BBU above) send to the described first ginseng
Number information.
, can be according to solicited message after the BBU side bases band plate receives the broadcast message in specific implementation process
In some fields and certain construction rule, construct the response message required for RRU, then in the form of broadcast packet send out
The RRU is given, to complete the acquisition of the first parameter information.
Certainly, in specific implementation process, other modes can also be used to obtain the first parameter information, this Shen from BBU sides
It is not limited please.
In specific implementation process, first parameter information can include many kinds, such as：
（1）Gateway information；
（2）IP information；
（3）Gateway information+RRUID；
（4）IP information+RRUID.
Certainly, in specific implementation process, first parameter information is not limited to above-mentioned four kinds, as long as the first parameter information
In comprise at least any one in gateway information or IP information.Based on different application environments, can use different
First parameter information detects to RRU links, more convenient, flexible, and more targetedly, its accuracy is also higher.
In specific implementation process, after M the first parameter informations are obtained based on step S201, it is possible to perform step
S202：By the initial parameter information progress of each first parameter information in the M the first parameter informations and the RRU
Match somebody with somebody, obtain a matching result；
In specific implementation process, the process for obtaining matching result, as shown in figure 4, may include steps of：
S401：Judge to whether there is in the M the first parameter informations exceed the first N number of parameter information with it is described original
Parameter information is inconsistent, wherein, N is the integer more than or equal to 1 and less than or equal to M；
Assuming that the first parameter information is gateway information obtained in step S201, and the original gateway information of the RRU is：
192.168.0.1；
Assuming that in step S301,5 are obtained altogether（M）Individual gateway information, it is respectively：
①192.168.0.1
②192.168.1.1
③192.168.0.1
④192.168.0.1
⑤192.168.0.1
There it can be seen that having 4 gateway informations and original gateway information matches in 5 gateway informations, only is 2. individual
Gateway information mismatches with original gateway information.
In specific implementation process, by M the first parameter informations（Gateway information before such as）With the original first ginseng
When number information is matched, just itself and initial parameter information can be matched in one the first parameter information of every acquisition,
Just it can be matched with initial parameter information one by one after whole M the first parameter informations are obtained, to this application
It is not restricted.
S402：If it does, obtaining the first matching result, first matching result is used to characterize the M first ginseng
Number information and the initial parameter information are inconsistent；
Assuming that in step S301, set N values are 0, are believed due to the gateway information more than 0 be present with original gateway
Breath matching, so obtaining the first matching result, first matching result illustrates 5 gateway informations and original gateway information
Mismatch.
S403：If it does not, obtaining the second matching result, second matching result is used to characterize the M first
Parameter information is consistent with the initial parameter information.
And if it is assumed that in step S301, set N values are 2, due to only existing a gateway information and original net
Information matches are closed, so obtaining the second matching result, second matching result illustrates 5 gateway informations and original gateway
Information matches.
Situation enumerated above to obtain multiple first parameter informations and initial parameter information is matched, in this feelings
Under condition, fully ensured that judge RRU link whether the accuracy of failure, and can with flexible modulation M, N value therein, so
Realize flexible.
And it is exactly the situation that M is 1 to have a kind of special circumstances, in this case, N values are 0, that is, obtain gateway every time
After information, all matched with original gateway information, as long as in the case of appearance is unmatched, determining that RRU link occurs
Failure.In this case, it can guarantee that the link information in time, efficiently knowing RRU.
Certainly, in specific implementation process, practical situations can be based on, determine different M, N values, the application is not done
Limitation.
In specific implementation process, based on step after a matching result is obtained based on step S202, it is possible to perform
Step S203：Judge whether the matching result meets a preparatory condition；
In specific implementation process, the deterministic process, that is,：
It is consistent with the initial parameter information to judge whether the matching result characterizes the M the first parameter informations.
Such as：After being judged based on step S401, the matching result that is obtained is the first matching result, that is, institute
State M the first parameter informations and the initial parameter information is inconsistent, so also just illustrate that the matching result is unsatisfactory for presetting
Condition.
And after being judged if based on step S401, the matching result obtained is the second matching result, that is,
The M the first parameter informations are consistent with the initial parameter information, so also just illustrate that the matching result meets default bar
Part.
S204：When the matching result is unsatisfactory for the preparatory condition, it is abnormal to determine that the RRU links occur.
Under normal circumstances, if M the first parameter informations and initial parameter information mismatch, illustrate what is be connected with RRU
BBU changes, so also just there is exception in explanation RRU link.
In specific implementation process, after determining that exception occur in the RRU links based on step S204, it can also carry out
Following operation：
Reset the RRU.
In specific implementation process, the reseting procedure of the RRU, that is, the operation for restarting RRU is performed, allow RRU to perform
Save oneself, during trial re-establishes communication link.
In order that the application that those skilled in the art can understand more in detail, example below two, three, four
By with different application environments, there is abnormal process to introduce detection RRU links respectively.
Embodiment two
In the present embodiment, mainly introduce in UMTS ((Universal Mobile Telecommunications
System:UMTS) in product, when the BBU being connected with RRU changes, because topology information does not change
Become, so in the case of causing RRUID also without changing, whether the link for how detecting RRU goes wrong.
Assuming that：RRU is connected on the interface board of a BBU, first deletes the configuration information of the RRU, then by the RRU things
Reason is connected on same BBU another interface board, then configures the RRU using same configuration information.
As shown in figure 5, the link of the RRU can be detected in the following way：
S501：RRU pre-saves the gateway information of oneself, IP information and RRUID, such as：
Gateway information is：200.254.3.16
IP information is：200.254.0.8
RRUID is：11
S502：After RRU normal works, broadcast request information is sent to BBU side joints oralia every prefixed time interval；
S503：The broadcast response message that BBU side joints oralia is replied based on the broadcast message is obtained, such as including following letter
Breath：
Gateway information is：200.254.4.16
IP information is：200.254.0.8
RRUID is：11
S504：The broadcast response message that analyzing step S503 is received, and by its gateway information with original preservation, IP information
Matched with RRUID, as long as there is an information to mismatch, it is determined that RRU links change, it can be seen that wherein IP information
It is all consistent with raw information with RRUID, and gateway information is inconsistent, so determine that RRU links break down, and carry out restarting RRU
And the operation that RRU saves oneself, to attempt to recover RRU links.It is of course also possible to after repeatedly comparing, with RRU described in accurate judgement
Whether link goes wrong, and due to being described in embodiment one, will not be repeated here.
From the present embodiment as can be seen that if being matched using multiple parameters, even if occurring in which that certain is several
The situation of parameter matching, but simply by the presence of the parameter for being unable to accurate match, still can interpolate that out that RRU link appearance is different
Often, so judgement is more accurate.
Embodiment three
In this example, it is assumed that the following two kinds situation：
1. RRU is connected on the interface board of a fixing groove position, and configured.After RRU normally starts, hold
It is about to this interface board and pulls another groove position of insertion together with optical fiber.
2. a RRU normally started is directly connected on another BBU from a BBU.
In such a case, it is possible to RRU links are detected in the following way：
RRU timings are sent to BBU side bases band plate to broadcast the message, and specially address request, main request obtain gateway
Information；
BBU side joints oralia replys broadcast response message after the broadcast message is received；
After RRU receives response message, the response message will be parsed, by gateway information therein and the gateway information to prestore
It is compared, if the field compared is inconsistent, it is possible to think that RRU links break down, restart RRU and RRU certainly
The operation rescued, to attempt to recover RRU links.
Example IV
In the present embodiment, describe in CDMA (Code Division Multiple Access:Also known as CDMA)
In product, RRU links exception how is detected.
RRU pre-saves the IP information of oneself, such as：IP information is：200.254.0.8；
After RRU normal works, broadcast request information is sent to BBU side joints oralia every prefixed time interval；
The broadcast response message that BBU side joints oralia is replied based on the broadcast message is obtained, such as including following information：IP
Information is：200.254.0.7；
The broadcast response message that receives of parsing previous step, and by its IP information with original preservation due to broadcasting response message
In IP information and original preservation IP information and mismatch, so explanation RRU links break down, execution restart RRU and
The operation that RRU saves oneself, to attempt to recover RRU link.
