Description
Technical field
The present invention relates to the telecommunication switching system field, relate in particular to a kind of call limitation method and system.
Background technology
Along with finishing of China Telecom's reorganization, formed three tame full-service operators, every family operation commercial city has fixed network and mobile network's operation licence plate.Competition between the operator has expanded to the competition of full-service from the competition of single business in the past, one of key point that the control ability of the interconnection and interflow between the network is competed as network utility, need abundanter control strategy more flexibly, such as, the interconnection and interflow between the inner heterogeneous networks of operator and the control strategy of the interconnection and interflow between the different operators network obviously should be different to some extent.
Like this; will higher requirement be proposed to interconnecting between the network; such as inter-network settlement; equalizing traffic volume; illegal Call Intercept; functions such as call number standard just need higher flexibility; thereby improve on the one hand Traffic Distribution ability between the net of operator; reduce improper inter-network settlement dispute; improve the control ability of operator on the other hand to traffic between net; more from satisfying the angle of operation and client's interests; realize that the controllable of traffic limit between net; such as initiatively refusing improper call source; the protection user avoids " harassing and wrecking "; limit improper call source for another example; alleviating the non-normal consumption to system resource, and the protection proper communication is unimpeded unaffected etc.
At present, above-mentioned functions mainly concentrates on gateway exchange and finishes.Concrete, China Telecom's regulation and stipulation adopts black and white lists and authentication to realize, the former is used for according to rear subscriber number or goes into the relaying identification code, forbid/allow some calling subscriber or from a certain calling of going into the calling of relaying to some object codes, in the prior art, blacklist and white list are used with restriction call, and principle is as shown in table 1:
| Calling Side | Callee side | Whether tackle |
| Black | Black | Interception |
| Black | In vain | Let pass |
| In vain | Black | Let pass |
| In vain | In vain | Let pass |
| Black | ??-- | Interception |
| In vain | ??-- | Let pass |
| ??-- | Black | Interception |
| ??-- | In vain | Let pass |
| ??-- | ??-- | Let pass |
Table 1
And authentication is used to differentiate the user of other carrier network present networks of whether having the right to use, and after authentication is passed through, just can do to carry out call proceeding.For the calling that other carrier network is come in, gateway exchange is general according to " rear subscriber number " or " going into relaying " Query Database, determines whether to give call proceeding.
In recent years, some equipment producer is for improving the flexibility of call blocking, proposing limit exhales the notion of group: Fig. 1 in the prior art, use limit to exhale the principle schematic of group restriction call, as shown in Figure 1, the calling subscriber enrolls a caller limit and exhales group, the called subscriber enrolls another limit and exhales group, and set up two limits and exhale calling relation between the group (forbid or allow), make the user can call out a part of user, restriction call another part user realizes that a kind of limit between blacklist (can not call out) and the white list (can both call out) is exhaled strategy except that white list, be called " gray list ".
" ash " of this " gray list " is the user, i.e. " ash " on " space ", so its limitation is apparent in view, makes a concrete analysis of as follows:
1) range of application is less
In general, existing network does not also have the user of certain particular range to forbid/allow the user's of certain particular range of calling demand, even have, also can realize by the mode of distributing specific analysis inlet to enter the jack per station analyst coverage at the calling subscriber, to realize that promptly the user of certain particular range forbids/allow calling out the user of certain particular range, gray list is not a unique channel, and there is multiple alternative method in prior art, thereby the range of application of gray list is less in the prior art.
2) can not provide dynamic restriction strategy
No matter be existing black and white lists of telecommunication specification and authentication, still above-mentioned " gray list " all is a kind of changeless restriction strategy, since be that what to fix promptly is regular, also just is very easy to be found and study.
3) flexibility of call blocking is lower
In the existing network operation, limit illegal call source if desired, at first will confirm its illegal identity, but confirming to need illegal act as foundation before it is illegal identity, and confirm that the process of illegal act is the process of infringement operation and user benefit in fact.And be accurately to grasp its illegal act of analysis that its illegal identity just needs the longer time, this exactly causes the more major injury to operation and user benefit, thereby become a kind of knot that can't untie, it has its source in and does not consider disabled user's illegal relatively property, absolute thinks that it is illegal or legal, causes it to form very obviously infringement before becoming " disabled user ".
So, adopt the existing call method for limiting can not in time find illegal call source, and Existing policies is only considered absolute limitations.Though time response is supported in call blocking, promptly some time period does not come into force, and some time period comes into force, and with regard to certain time point, is absolute restriction or does not limit.There is gap between the reality of this strategy and network operation, do not consider the relativity of restriction, so the flexibility of call blocking is lower.
For " gray list " of another aspect of proposing with the present invention, i.e. " gray list " on " time " distinguished, and " gray list " of foregoing description is also referred to as " limit is exhaled group ".
Summary of the invention

Embodiment
Basic thought of the present invention is: by gray list is set, when receiving call request, tackle according to the calling that specific call interception ratio pair and gray list mate.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
Explanation once more, for " gray list " of another aspect of proposing with the present invention, i.e. " gray list " on " time " distinguished, and " gray list " described in the background technology is called " limit is exhaled group ", promptly " gray list " that after this occurs all refers to the gray list on the present invention's " time " meaning.
The present invention is applied to the control point of cross-net call--gateway exchange emphatically, and Fig. 2 is a call limitation method schematic flow sheet of the present invention, and as shown in Figure 2, call limitation method of the present invention generally comprises following steps:
Step 21: call restriction system configuration gray list.
Gray list generally comprises: parameters such as trunk group and/or user ID, interception ratio.
Generally according to trunk group and/or user ID configuration gray list, can dispose a gray list, also can dispose many parts of gray lists, trunk group described here includes trunk group and outgoing trunk group, according to trunk group configuration gray list the time, can dispose respectively, promptly dispose incoming trunk group gray list and outgoing trunk group gray list respectively, described trunk group includes but not limited to: TDM (Time Division Multiple, time division multiplexing) relaying, SIP (Session Initiation Protocol, session initiation protocol) relaying; Described user ID comprises calling subscriber identification and CSI called subscriber identification, during according to user ID configuration gray list, also can dispose respectively, promptly dispose calling subscriber identification gray list and CSI called subscriber identification gray list respectively, the changed course user ID when forwarding subscriber sign during preceding commentaries on classics and changed course also can be called calling subscriber identification.
User ID refers generally to Subscriber Number, prefix, Caller Category, called subscriber's attribute etc.
Need to prove that this step also can dispose white list and/or blacklist outside the configuration gray list, certainly, also can the user be configured in the list that is used for limiting.
Step 22: when call restriction system is received call request, judge whether and need tackle judgement to current calling according to the gray list of described configuration, if, execution in step 23; Otherwise, execution in step 25.
If step 21 has only disposed gray list, then whether need current calling to be tackled and be judged as according to the gray list of described configuration: judge the trunk group information of current calling and/or user ID whether with pre-configured gray list in trunk group and/or user ID coupling, concrete, trunk group and/or user ID in the trunk group information of current calling and/or user ID and the pre-configured gray list are mated, judge which gray list current trunk group information and/or user ID belong to.
If also disposed white list and/or blacklist in the step 21, then need current calling to be tackled and be judged as: trunk group and/or user ID coupling in current trunk group information and/or user ID and the pre-configured gray list, and trunk group and/or user ID coupling in the pre-configured white list of current trunk group information and/or user ID discord according to the gray list of described configuration.
Call restriction system is supported blacklist, (blacklist represented to tackle whole callings when the mixing of white list and gray list was provided with, white list is represented to let pass and is all called out, gray list is represented to call out according to interception ratio interception part), if a plurality of matching results, include but not limited to the priority orders of " white list＞gray list＞blacklist ", as long as promptly having white list just all to let pass calls out, otherwise, when not having white list and gray list being arranged, interception proportional parts interception according to gray list is called out, there is not white list, when not having gray list and blacklist being arranged, interception is all called out.
For example, if the calling subscriber identification coupling in calling subscriber identification of calling out and the pre-configured gray list, and the coupling of the CSI called subscriber identification in the CSI called subscriber identification of this calling and the pre-configured white list, then call out this moment and should be continued, promptly do not need judgement to be tackled in current calling according to the gray list of described configuration.
Again for example, according to incoming trunk group and outgoing trunk group, obtain two matching results respectively, promptly calling number (changeing before containing or the changed course number) and called number belong to a restriction list respectively.Two matching results of analysis-by-synthesis include but not limited to the priority orders of " white list＞gray list＞blacklist ".
Table 2 is the example that a kind of gray list and black and white lists are used the restriction call logic:
| Calling Side | Callee side | Whether tackle |
| Ash | In vain | Let pass |
| Ash | Black | According to grey ratio interception |
| Ash | ??-- | According to grey ratio interception |
| In vain | Ash | Let pass |
| Black | Ash | According to grey ratio interception |
| Ash | Ash | Get tackling of two ashes than small scale |
| ??-- | Ash | According to grey ratio interception |
Table 2
Step 23: call restriction system judges whether to tackle current calling according to gray list, if, execution in step 24; Otherwise, execution in step 26.
Be specially: obtain current Call Intercept ratio in the gray list, determine according to this ratio whether current calling will be blocked.Here, the mode that determines current calling whether will be blocked according to the interception ratio can have multiple, for example accumulate mode, random fashion (random number algorithm) etc., if current Call Intercept ratio is 10% in the gray list, when then adopting accumulate mode to tackle, can be after letting slip such calling 9 times, once tackle, and when adopting random fashion to tackle, can be in 10 such callings interception wherein 1 time at random, all the other are let slip for 9 times.
Need to prove, when two or more gray lists can supply to judge, can judge according to minimum interception ratio, the method that the interception ratio is selected includes but not limited to select to tackle and requires a low side, if promptly gray list 1 and gray list 2 all with this call matches, the interception ratio of gray list 1 is 20%, and the interception ratio of gray list 2 is 30%, then selects this moment according to the interception ratio of gray list 1 call blocking to be carried out in this calling.Have two or more gray lists specifically how to select and can set when judging by the client, also can be in system default configuration, do not constitute limitation of the invention.
Before judging whether to tackle current calling according to gray list, can also dynamically adjust the interception ratio in the gray list according to call case, certainly, whether need the interception ratio is dynamically adjusted is option, adjust if desired, then also need gray list interception ratio dynamically-adjusting parameter is configured, table 3 is the parameter configuration example that a kind of gray list interception ratio is dynamically adjusted, when parameter that its configuration interception ratio is dynamically adjusted is carried out the dynamic adjustment of Call Intercept, adopt step-length to adjust method:
| The gray list number | Initial interception ratio | The interception ratio is adjusted step-length | The initial call amount | The call volume step-length |
| Number 1 | ??50％ | 10 percentage points | ??100 | ??10 |
Table 3
The implication of configuration is in the table 3, and when reaching 100 call volumes, the interception ratio is 50%, and when call volume is increased to 110 (100+10), promptly calls out variable quantity and reach the adjustment step-length, and the interception ratio is adjusted into 60% (50%+10%); When call volume when 110 are increased to 120, the interception ratio is adjusted into 70%, i.e. (60%+10%), by that analogy; Otherwise call volume reduces at 110 o'clock from 120, and the interception ratio is adjusted into 60% (70%-10%), and call volume reduces at 100 o'clock from 110, and the interception ratio is adjusted into 50% (60%-10%).
The mode that the dynamic parameter of adjusting of configuration interception ratio is carried out the dynamic adjustment of Call Intercept can have multiple, is not limited to above-mentioned step-length and adjusts method.
Step 24: call restriction system is tackled current calling, and flow process finishes.
Step 25: call restriction system is carried out call blocking according to existing procedure, and flow process finishes.
Here, promptly carry out call blocking according to the rule shown in the table 1.Do not belong to the situation of any limit table for call information, current calling continues.
Step 26: the call restriction system current calling that continues, flow process finishes.
Fig. 3 is a call restriction system structural representation of the present invention, and as shown in Figure 3, call restriction system of the present invention comprises grey list configuration unit 31, call request receiving element 32, judging unit 33, restriction performance element 34, wherein,
Grey list configuration unit 31 is used to dispose gray list.
Need to prove that the gray list of grey list configuration unit 31 configurations generally comprises: parameters such as trunk group and/or user ID, interception ratio.Generally according to trunk group and/or user ID configuration gray list, can dispose a gray list, also can dispose many parts of gray lists, user ID refers generally to Subscriber Number, prefix, Caller Category, called subscriber's attribute etc.
Call request receiving element 32 is used for the receipt of call request, and notice judging unit 33.
Judging unit 33, be used for after the notice of receiving call request receiving element 32, gray list according to configuration in the grey list configuration unit 31, judge whether and to tackle judgement according to gray list to current calling, and when needs are tackled judgement according to gray list to current calling, be sent to restriction performance element 34 further according to tackling judgement with the gray list of current call matches in the grey list configuration unit 31, and with judged result.
Here, whether need current calling to be tackled and be judged as according to the gray list of described grey list configuration unit 31 configurations: judge the trunk group information of current calling and/or user ID whether with the pre-configured gray list of grey list configuration unit 31 in trunk group and/or user ID coupling, concrete, trunk group and/or user ID in the gray list that the trunk group information of current calling and/or user ID and grey list configuration unit 31 is pre-configured are mated, and judge which gray list current trunk group information and/or user ID belong to.
Judging unit 33 is specially according to tackling judgement with the gray list of current call matches in the grey list configuration unit 31: obtain current Call Intercept ratio in the gray list, determine according to this ratio whether current calling will be blocked.
Need to prove, can judge according to minimum interception ratio when judging that the method that the interception ratio is selected includes but not limited to select to tackle and requires a low side as two or more gray lists.
Restriction performance element 34 is used for according to the judged result from judging unit 33, carries out operation accordingly.
Here, judged result is that replay call or interception are called out.
This system also comprises black and white lists dispensing unit 35, is used to dispose blacklist and/or white list.
Judging unit 33, also be used for after the notice of receiving call request receiving element 32, blacklist and/or white list according to configuration in gray list that disposes in the grey list configuration unit 31 and the black and white lists dispensing unit 35, judge whether and to tackle judgement according to gray list to current calling, and when needs are tackled judgement according to gray list to current calling, be sent to restriction performance element 34 further according to tackling judgement with the gray list of current call matches in the grey list configuration unit 31, and with judged result.
Here, need tackle current calling according to the gray list of described grey list configuration unit 31 configurations and be judged as: trunk group and/or user ID coupling in the pre-configured gray list of current trunk group information and/or user ID and grey list configuration unit 31, and trunk group and/or user ID coupling in the pre-configured white list of current trunk group information and/or user ID discord black and white lists dispensing unit 35.
This system also comprises dynamically-adjusting parameter dispensing unit 36 and dynamic adjustment unit 37, wherein,
Dynamically-adjusting parameter dispensing unit 36 is used to dispose the parameter that the interception ratio is dynamically adjusted.
Here, whether be option, and the mode that the dynamic parameter of adjusting of configuration interception ratio is carried out the dynamic adjustment of Call Intercept includes but not limited to step-length adjustment method if needing by the dynamic parameter of adjusting of configuration interception ratio in dynamically-adjusting parameter dispensing unit 36.
Call request receiving element 32 also is used for the receipt of call request, and notifies dynamic adjustment unit 37.
Dynamic adjustment unit 37, be used for after the notice of receiving call request receiving element 32, according to the dynamic parameter of adjusting of the interception ratio of dynamically-adjusting parameter dispensing unit 36 configurations, interception ratio to gray list in the grey list configuration unit 31 is dynamically adjusted, and is adjusting Inform when done judging unit 33.
Embodiment 1
This case description gray list carries out the processing procedure of call blocking, and need all carry out the processing of this example going into trunk side and out-trunk side, Fig. 4 is the embodiment of the invention 1 a call limitation method schematic flow sheet, and as shown in Figure 4, the embodiment of the invention 1 call limitation method mainly may further comprise the steps:
Step 41: call restriction system is according to relaying or user ID configuration gray list, blacklist and white list.
Relaying described here includes relaying and out-trunk (relaying includes but not limited to TDM relaying, SIP trunk), needs configuration respectively; Described user ID comprises calling number (preceding commentaries on classics or changed course number) and called number, needs configuration respectively.
If distinguish different call blockings with user ID in conjunction with relaying according to relaying, then at first obtain the call blocking inlet according to relaying, what come the match user place is which gray list, blacklist or white list according to user ID (comprising Subscriber Number, prefix, Caller Category, called subscriber's attribute etc.) again.
If only distinguish call blocking according to user ID, then according to user ID (comprising Subscriber Number, prefix, Caller Category, called subscriber's attribute etc.) directly the match user place be which list.
Step 42: call restriction system is judged trunk information in current trunk information and/or user ID and the pre-configured gray list and/or user ID, and whether the match is successful, if, execution in step 43; Otherwise execution in step 45.
Blacklist and white list are handled same gray list, only describe the processing of gray list below:
Check in the gray list of this relaying configuration whether have current user ID according to current trunk information, comprise Subscriber Number, prefix, Caller Category, called subscriber's attribute etc., if exist, then the match is successful in expression, otherwise expression it fails to match.
For the call restriction system that has disposed trunk group gray list and user ID gray list simultaneously, such matching operation betides four kinds of occasions:
The calling subscriber identification of incoming trunk group (preceding commentaries on classics or changed course user ID);
The CSI called subscriber identification of incoming trunk group;
The calling subscriber identification of outgoing trunk group (preceding commentaries on classics or changed course user ID);
The CSI called subscriber identification of outgoing trunk group.
Step 43: call restriction system is used the logic of restriction call according to gray list, blacklist and white list, judges whether to refuse to call out, if, execution in step 44; Otherwise execution in step 45.
To go into relaying is example, and the processing of out-trunk is with going into relaying:
Gray list, blacklist and white list are used the restriction call logic and include but not limited to relevant entry in the example as described in Table 2.After the last step obtains the matching result of the calling number (preceding commentaries on classics or changed course number) of relaying and called number respectively, inquire about this table, suppose that calling number (preceding commentaries on classics or changed course number) matching result is a gray list, the called number matching result also is a gray list, then according to this table get interception ratio in two gray lists less carry out Call Intercept.
The realization of this interception ratio includes but not limited to the random number algorithm, is 10% as the interception ratio, then represents only interception wherein 1 time at random of 10 such callings, and all the other are let slip for 9 times.
Whether the interception ratio needs dynamic the adjustment is option, and the parameter configuration example that gray list interception ratio is dynamically adjusted includes but not limited to the described example of table 3, specifically implements to see example 2.
Step 44: the call restriction system refusal is called out, and flow process finishes.
Step 45: call restriction system allows replay call, and flow process finishes.
Embodiment 2
After present embodiment is described and according to call case the interception ratio in the gray list dynamically to be adjusted, judge whether that again interception calls out, wherein emphasis is described the method that the interception ratio is dynamically adjusted, but this method is not as the qualification to dynamic adjusting method.
The prerequisite of present embodiment is to need the various interception parameters of configuration, include but not limited to the described example of table 3, when two gray lists all had dynamic adjustment configuration, the method for selection included but not limited to tackle and requires a low side, how to select to set, do not constitute qualification this patent by the client.
Fig. 5 is the embodiment of the invention 2 call limitation method schematic flow sheets, and as shown in Figure 5, the embodiment of the invention 2 call limitation methods mainly may further comprise the steps:
Step 51: call restriction system is according to calling out situation of change, updating call amount data.
Call volume described here includes but not limited to the call number of unit interval, also can be the call volume of accumulation in a period of time.
For example, can be before reaching the initial call amount, whenever inserting new the calling, call volume adds 1, and after reaching the initial call amount, whenever inserting new the calling, call volume adds 1, during call release, call volume subtracts 1.
Step 52: call restriction system judges whether call volume reaches the initial call amount, if, execution in step 53; Otherwise, execution in step 55.
Consider when having only call volume to reach certain thresholding, dynamically adjust just feasiblely, whether need to carry out call blocking such as having only one, two calling not know where to begin.
Step 53: call restriction system judges whether call volume reaches the requirement of adjusting step-length, if, execution in step 54; Otherwise, execution in step 56.
With initial call amount 100, call volume step-length 10, initially to tackle ratio 50% be example, if current call volume is 100, when then reaching 100 call volumes, the interception ratio is 50%, and when call volume was increased to 110 (100+10), promptly call volume reached the adjustment step-length; Equally, if call volume reduces to 100 from 110, call volume also reaches the adjustment step-length.
Step 54: call restriction system is upgraded the interception ratio according to interception ratio step-length, and whether tackles calling by the interception ratio decision after upgrading, and flow process finishes.
With initial call amount 100, call volume step-length 10, initially tackle ratio 50%, it is example for 10 percentage points that step-length is adjusted in interception, if current call volume is 100, when then reaching 100 call volumes, the interception ratio is 50%, and when call volume was increased to 110 (100+10), promptly call volume reached the adjustment step-length, and the interception ratio is adjusted into 60% (50%+10%); When call volume when 110 are increased to 120, the interception ratio is adjusted into 70% (60%+10%), by that analogy; Otherwise call volume reduces at 110 o'clock from 120, and the interception ratio is adjusted into 60% (70%-10%), and call volume reduces at 100 o'clock from 110, and the interception ratio is adjusted into 50% (60%-10%).
Step 55: call volume does not reach the initial call amount, does not carry out Call Intercept, and flow process finishes.
Step 56: call volume does not reach the adjustment step-length, still carries out according to the original interception ratio of system, and flow process finishes.
