The embodiment of the present invention can be used for a kind of communications network system, in the communications network system include at least MME and
DNS.It is as shown in Figure 1 the interaction schematic diagram in domain name resolution process between MME and DNS.MME after generating TAI/APN domain name,
TAI/APN domain name can be carried in analysis request message, be sent to DNS；DNS by query configuration table, by allocation list with
There are all addresses MME/SGW/PGW of corresponding relationship to feed back to MME for the TAI/APN domain name；MME is according to self-demand later,
Suitable MME/SGW/PGW domain name is selected, and is sent to DNS；DNS receive MME transmission MME/SGW/PGW domain name after,
The address MME/SGW/PGW inquired can be fed back to MME, to complete domain name resolution process.It should be noted that in this hair
It in bright embodiment, is described by taking TAI domain name as an example, but the embodiment of the present invention is not limited in TAI domain name resolution process.
The embodiment of the present invention provides a kind of method of adjustment DNS configuration, as shown in Fig. 2, this method can be by Fig. 1
DNS is executed, and this method specifically includes:
Step 101, after receiving the analysis request message of TAI domain name, the operation flow that within a specified time generates note
Search whether there is historical record identical with TAI domain name in record.Wherein, historical record identical with TAI domain name if it exists, then
Execute step 102；Otherwise, step 104 is executed.
DNS can periodically transfer the relevant operation flow record of TAI domain name mapping from MME, and according to operation flow
The foundation of the completion database of information involved in record.Wherein, can periodically be considered as carrying out business according to some cycles
Process recording is transferred, or in the case where network environment allows, is obtained in real time.In embodiments of the present invention, for business
The acquisition mode of process recording, acquisition opportunity are not specifically limited, the adjustment demand that can be configured according to current DNS, by working
Personnel preset.
Above-mentioned specified time is specifically as follows currently for the phase of history time of cut-off time, or with it is current
The set for the historical time section that TAI domain name resolution process matches is carried out, it is not limited here.For example, above-mentioned specified time tool
Body can be 24 hours.In addition, can come according to the portfolio and network change frequency of DNS when above-mentioned specified time is arranged
It is set.
For example, specified time can be set to the shorter period for scene biggish for the portfolio of DNS, this
Sample can effectively avoid bringing excessively high load to DNS because data volume to be processed is excessive；It is lesser for the portfolio of DNS
For scene, specified time can be set to longer time section, thus can effectively avoid because data volume to be processed is too small
And it can not reflect true business flow processing situation.Similarly, what above-mentioned network change frequency mainly reflected is user at two
The frequency switched between adjoining area in the case of larger for network change frequency, needs to carry out error correction as early as possible, then for
Reduce the processing time, it may be necessary to by specified time set the shorter time, sufficient number can not only be got in this way
According to resource, while bring energy consumption in data handling procedure can also be reduced as far as possible and is reduced time-consuming；For network change frequency
The lesser situation of rate, it is contemplated that the frequency for generating switching is lower, then needs to obtain the operation flow record generated in for a long time,
Valid data can be analyzed and handled.It should be noted that setting specified time mode not only can be considered above-mentioned factor to
Data volume or data accuracy bring image, can also be by considering other factors and the completion of currently practical scene being combined to refer to
The setting fixed time, it is not limited here.
In embodiments of the present invention, historical record identical with TAI domain name refers to the business within a specified time generated
In process recording, operation flow record identical with TAI domain name corresponding to the analysis request message received.
Step 102 determines in historical record with the presence or absence of failed operation flow record.Wherein, if it exists not successfully
Operation flow record, then follow the steps 103；Otherwise, step 104 is executed.
It should be noted that failed operation flow record includes at least operation flow time-out without response and operation flow
At least one of failure.After the foundation for completing database, the business generated in specified time will include in the database
Whether the processing result of process recording, the i.e. operation flow record succeed.
For example, the storage mode of all data can be as shown in Table 1 interior in an operation flow record in database
Hold.
Table one
As shown above, every operation flow record includes at least TAI domain name, SGW domain name and the address SGW in database.
The reason of whether succeeding for the ease of statistical procedures, and operation flow is caused to fail, every operation flow record may be used also
To include that dns resolution unsuccessfully identifies, operation flow time-out identifies and operation flow success flag.In addition, in order to establish data
More targeted when library, every operation flow also all should include the operation flow triggered time, thus can be for certain for the moment
Between the operation flow that generates in section counted, analyzed.
It should be noted that operation flow record can be stored according to form shown in above-mentioned table one, it can also be by
It is stored according to other convenient for the mode of dns lookup, it is not limited here.
Step 103, adjustment meet the domain name system DNS configuration of specified requirements.
Wherein, the DNS configuration for meeting specified requirements includes at least: under the same terms in operation flow record, business
Success rate is less than first threshold and/or business number of attempt is greater than the DNS configuration of second threshold.
In embodiments of the present invention, service success rate is specifically as follows operation flow success flag under the same terms and is
The total quantity that the quantity of the record of " Y "/all operation flows record；Business number of attempt is then all industry under the same terms
The total degree of business record.
It should be noted that first threshold and second threshold can by staff according to historical data or empirical value into
Row is preset, and it is not limited here, for example, first threshold can be set to 30%, second threshold can be set to 50.
Step 104 is returned the result by DNS configuration.
The result of above-mentioned return refers to the IP address obtained according to traditional TAI domain name mapping mode.
The embodiment of the present invention can be after receiving the analysis request message of TAI domain name, the industry that within a specified time generates
Search whether there is historical record identical with TAI domain name in business process recording；History note identical with TAI domain name if it exists
Record, and there are failed operation flow records in historical record, then adjustment meets the DNS configuration of specified requirements, wherein meets
The DNS configuration of specified requirements includes at least: under the same terms in operation flow record, service success rate is less than first threshold
And/or business number of attempt is greater than the DNS configuration of second threshold.It can be seen that the embodiment of the present invention DNS configure there may be
Leakage in the case where mismatching, can configure original DNS and be adjusted, to pass through caused by reducing due to TAC changes
There is the probability of mistake in the address that inquiry of the domain name constructed by MME is arrived.In addition, in embodiments of the present invention, judging that DNS configuration is
It is no there are leakage, mismatch the case where, mainly according to generated operation flow record in service success rate and business attempt
Number, so, the adjustment process that DNS can be made to configure are more targeted, so that emphasis adjustment process is locked in
In the configuration of DNS corresponding to changed TAC, it thus can further solve to pass through MME caused by due to TAC changes
Constructed inquiry of the domain name to address occur mistake problem.
When adjusting DNS configuration, in order to ensure the DNS configuration after adjusted is able to ascend the standard of TAI domain name resolution process
True rate, in an implementation of the embodiment of the present invention, DNS can be found and failed Business Stream from historical record
The identical history subrecord of the SGW domain name of Cheng Jilu and the address SGW adjusts DNS according to the quantity of operation flow subrecord later
Configuration.Therefore, on the basis of implementation as shown in Figure 2, it is also implemented as implementation as shown in Figure 3.Wherein,
Before executing step 103 adjustment and meeting the DNS configuration of specified requirements, step 105 and step 106, step 103 can also be performed
It can be implemented as step 201:
Step 105, the SGW domain name for obtaining every failed operation flow record and the address SGW.
From operation flow shown in table one record in it can be seen that, each TAI domain name can exist corresponding SGW domain name and
The address SGW, but same TAI domain name can correspond at least one SGW domain name, and due to the corresponding pass between SGW domain name and the address SGW
System is it is known that same TAI domain name can correspond at least one address SGW.Therefore, in embodiments of the present invention, failed industry
It is engaged in process recording, may there is the combination of multiple groups corresponding with TAI domain name SGW domain name and the address SGW.For example, not at
In the operation flow record of function, the corresponding SGW domain name of certain TAI domain name is A and B, and the corresponding address SGW A is 1.1, and B is corresponding
The address SGW is 2.2.
Step 106 searches history subrecord identical with SGW domain name and the address SGW from historical record, and according to SGW
Domain name and the address SGW, are grouped history subrecord, obtain at least one operation flow subrecord.
Wherein, the SGW domain name of all subrecords is identical with the address SGW in each operation flow subrecord.
Referring to the content enumerated in step 105, after being grouped to history subrecord, 2 operation flow notes are obtained
Record, one of operation flow subrecord include that SWG domain name is the operation flow record that the address A and SGW is 1.1, another industry
Business process subrecord includes that SWG domain name is the operation flow record that the address B and SGW is 2.2.
Step 201, according to the quantity of operation flow subrecord, adjustment meets the DNS configuration of specified requirements.
The quantity of operation flow subrecord refers to that all operation flows record total in this operation flow subrecord
Quantity, for example, it is 5 that SWG domain name, which is the quantity that the operation flow that the address A and SGW is 1.1 records corresponding operation flow subrecord,
Item, SWG domain name are that the quantity that the operation flow that the address B and SGW is 2.2 records corresponding operation flow subrecord is 10.
Above content, it can be ensured that the more targeted process for completing DNS configuration adjustment is adjusted DNS configuration
Whole process needs to consider DNS configuration corresponding SGW domain name and the address SGW, ensures that DNS adjusted matches in this way
Set with adjustment before the corresponding identical SGW domain name of DNS configuration and the identical address SGW, thus avoid DNS configure deposit after the adjustment
The case where mismatching.
It can be adopted in an implementation of the embodiment of the present invention for the difference of the quantity of operation flow subrecord
Different processing modes is taken, to realize the adjustment of DNS configuration.Therefore, on the basis of implementation as shown in Figure 3, may be used also
To be embodied as implementation as shown in Figure 4.Wherein, step 201 is being executed according to the quantity of operation flow subrecord, adjustment is full
Before the DNS configuration of toe fixed condition, step 107 can also be performed, step 201 can be implemented as step 301 to step
305:
Step 107, the quantity for obtaining operation flow subrecord.
If step 301, the quantity of operation flow subrecord are one, inquired after the tac-lb value in TAI domain name is added 1
The identical DNS configuration to be selected of corresponding with analysis request message DNS Configuration Type.
As shown in Table 1, tac-lb and tac-hb is included at least in TAI domain name.TAI Domain Name Form registering sites is tac-lb < TAC-
low-byte>.tac-hb<TAC-high-byte>.tac.epc.mnc001.mcc460.3gppnetwork.org.Wherein, <
TAC-low-byte >: refer to X3X4, is that tac is two low, is indicated with tac-lb；<TAC-high-byte>: referring to X1X2, is tac high
It two, is indicated with tac-hb.In actual application, X1 and X2 are distributed unitedly by operator, and X3 and X4 are then by each
Province voluntarily distributes.
Step 302 judges whether DNS configuration to be selected meets regularization condition.Wherein, if meeting regularization condition, step is executed
Rapid 303；Otherwise, step 304 is executed, and after executing the step 304, circulation executes step 302, until finding satisfaction adjustment item
Until the DNS to be selected configuration of part.
Wherein, the DNS to be selected configuration for meeting regularization condition includes at least: service success rate is greater than third threshold value and/or industry
The DNS that business number of attempt is greater than the 4th threshold value is configured.
It should be noted that third threshold value and the 4th threshold value can by staff according to historical data or empirical value into
Row is preset, and it is not limited here, for example, third threshold value can be set to 90%, the 4th threshold value can be set to 50.
DNS to be selected configuration is written in the allocation list of TAI domain name by step 303, and is certainly by DNS configuration flag to be selected
Adapt to result.
Step 304 inquires DNS configuration class corresponding with analysis request message after the tac-lb value in TAI domain name is added 1 again
The identical DNS configuration to be selected of type.
It should be noted that tac-hb value is constant always during above-mentioned adjustment tac-lb value.
If the quantity of step 305, operation flow subrecord is at least two, the priority of current DNS configuration is reduced.
On the basis of implementation as shown in Figure 4, it is also implemented as implementation as shown in Figure 5.Wherein, it walks
If the quantity of rapid 305 operation flow subrecord is at least two, the priority of current DNS configuration is reduced, can be implemented
For step 401:
If the quantity of step 401, operation flow subrecord is at least two, the priority that current DNS is configured is adjusted
For the lowest priority in the corresponding DNS configuration of all operation flow subrecords.
It can be seen that the case where quantity for operation flow subrecord is one, it can be by the tac-lb in TAI domain name
Value carries out after adding 1, the identical DNS configuration to be selected of inquiry DNS Configuration Type corresponding with analysis request message, if this is to be selected
DNS configuration is unsatisfactory for current demand, then 1 tac-lb value will have been added to add 1 again, and so on, until it is current to inquire satisfaction
The DNS to be selected of demand is configured, and the DNS configuration to be selected is configured as DNS adjusted；And for operation flow subrecord
The case where quantity is at least two, it is contemplated that there are alternative DNS configurations, therefore, the priority that can be configured by adjusting DNS
The priority of current DNS configuration to be adjusted is reduced, the priority that thus can indirectly configure other DNS improves,
To complete the adjustment of DNS configuration.
It should be noted that above-mentioned TAI domain name resolution process, be also applied to such as Routing Area identification (English:
Routing Area Identification, RAI) in domain name resolution process and other implementations.It also means that, for existing
