Embodiment
The embodiment of the invention provides method, system and the equipment of calling out access control, can be implemented in to call out to insert to call out access control before, improves the voice quality of calling out.For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, below with reference to accompanying drawing, the embodiment of the invention is further described.
Call Cut-in control method embodiment one:
With reference to Fig. 2, be call Cut-in control method embodiment one flow chart in the inventive embodiments, MGW adopts and calls out irrelevant detection technique, detect the carrying fault whether between MGW and the opposite equip. office direction, when detection obtain and the opposite equip. office direction between the carrying fault time, report described fault corresponding equipment sign (ID, Identifier); The MSC server is carried out the calling access control according to the described fault corresponding equipment ID that reports to the calling between MGW and the opposite equip. office direction, below is elaborated by concrete steps:
21, MGW starts and calls out irrelevant detection technique, detect and the opposite equip. office direction between carrying fault whether;
Can indicate the MGW start detection according to calling out by Mc interface by the MSC server, also can determine whether start detection mechanism according to the entry condition of configurations such as start-up time by MGW.Different is, when coming start detection according to calling by the MSC server, may learn the voice quality of this calling calling before, and when determining whether start detection mechanism by MGW, can be without any start detection mechanism before calling out, and then the voice quality that guarantees all-calls is all unaffected, so, can be network be built up after with regard to start detection mechanism immediately.
Can adopt two-way forwarding to detect (BFD, Bidirectional Forwarding Detection) technology, Internet packet detector (PING, Packet Inter-Netework Groper) technology or other and call out the technology that message does not have direct relation detect the carrying fault whether between MGW and the opposite equip. office direction.
Below describe in detail to adopt the BFD technology be how to detect and the opposite equip. office direction between carrying fault whether:
With reference to Fig. 3, for adopting the carrying realization schematic diagram of fault whether between BFD technology for detection and the opposite equip. office direction, MGW31 is connected by the IP bearer network with other opposite equip.s 32, and opposite equip. can be physical entities such as RNC/BSC, MGW, router.When opposite equip. was BSC, the A interface of BSC needed IPization, supported the IP carrying.Opposite equip. 32 has one or more physical interfaces, and primary ip address is chosen from each interface in the one or more IP of each interface configuration address.So-called primary ip address is meant the IP address that this physical interface can only could be deleted to the end, and other addresses on the interface are from the address.The primary ip address of representing each physical interface among Fig. 3 with IP0～IPn.MGW31 also has a plurality of physical interfaces usually, chooses one or more physical interface, chooses primary ip address at each interface.But, in the MGW31 side, if choose a physical interface, when causing all to detect, the Shi Zehui that breaks down lost efficacy, and choose too much, implement then more complicated, so choose two physical interfaces usually, the primary ip address of two of the MGW side physical interface correspondences is respectively among Fig. 3: IPm0, IPm1.
Set up the BFD connection of IPm0, set up the BFD connection of IPm1 simultaneously to IP0～IPn to IP0～IPn.MGW can send detection messages by the BFD isl cycle ground of setting up with opposite equip., if do not receive the detection messages of opposite end in the time of presetting, thinks that then fault has taken place certain part with the duplex channel of opposite equip..According to the BFD technology, can fast detecting has the carrying fault between MGW and the opposite equip. office direction.
Carrying between MGW31 and opposite equip. 32 office directions may be a partial fault, also may be whole faults.Can determine whether detected fault is reported according to certain strategy.For example, MGW31 among Fig. 3 is chosen the situation of two physical interfaces, detect BFD link fault all of the IP address (as IP0) of some opposite equip.s 32 as IPm0 and IPm1 simultaneously, could determine the carrying fault that this IP address (as IP0) is corresponding.(, show the whole faults of carrying of this equipment office direction if detect all the IP addresses learn opposite equip. 32 office directions as the fault all of IP0～IPn).
And Internet packet detector (PING, Packet Inter-Network Groper) technology is an internet, applications instrument, can determine the connectivity and the accessibility of network.PING can detect whether the network opposite equip. exists and whether network is normal.Its principle is: test the situation that connects end to end by sending ICMP (ICMP, Internet Control Massage Protocol) packet, and check the ICMP packet the node of process and equipment operate as normal whether.That is to say, can transmit a small data packets to opposite equip., receive it through opposite equip. feedback back by PING, according to response time and data loss rate, judge with the successful connection of opposite equip. whether, how are connection effect, speed.
When MGW self produces fault, can utilize existing equipment control mechanism of equipment or link detecting mechanism to detect, certainly, this testing mechanism is also irrelevant with calling.This testing mechanism can be used in combination with above BFD technology or PING technology, not using the total interface of MGW when above technology to connect when detecting with opposite equip., if the port that does not connect breaks down, then above-described BFD or PING technology can't detect and obtain, and the fault detection mechanism of this equipment itself can detect and obtains, therefore with the fault detection method and the BFD of this equipment disposition, technology combinations such as PING can detect this equipment of obtaining, existing all faults of carrying between opposite equip. and this equipment and the opposite equip..
22, when detection obtain and described opposite equip. office direction between the carrying fault time, MGW is reported to the MSC server with the pairing device id of fault;
Carrying fault between the described and opposite equip. office direction comprises the IP carrying fault between MGW port failure, opposite equip. port failure, MGW and the opposite equip. office direction.
In MGW, the corresponding relation of an IP address of equipment and device id can be set, with reference to table 1, for describing the fault message table of this corresponding relation.When detection obtains the BFD link failure of certain IP address, inquire about this table and can obtain this IP address corresponding equipment ID, and the device attribute of this equipment.Wherein, opposite equip. is represented in the opposite end, and itself represents MGW self.The fault corresponding equipment ID that inquiry is obtained is reported to the MSC server.
If MGW is when detecting the interface fault obtain this equipment or other fault by self testing mechanism, corresponding equipment ID is " N " in the then described fault message table, and device attribute is " own ", with reference to fault message table 1.
| Device id | Device attribute | The IP address |
| 0 | The opposite end | IP0 |
| 0 | The opposite end | IP1 |
| 0 | The opposite end | IP2 |
| 0 | The opposite end | ... |
| 0 | The opposite end | IPn |
| 1 | The opposite end | IP0 |
| 1 | The opposite end | IP1 |
| 1 | The opposite end | IP2 |
| 1 | The opposite end | ... |
| 1 | The opposite end | IPn |
| ... | ... | ... |
| N | Itself | IPm1 |

| N | Itself | IPmN |
Fault message table 1
23, the MSC server is carried out the calling access control according to the fault corresponding equipment ID that reports to the calling between the described equipment office direction.
Before call out inserting, the MSC server can be checked the device id that reports, and calls out the carrying fault whether between the equipment office direction that will insert to determine this, when fault, controls the access of current calling and subsequent voice calls.Because the pairing fault of described device id may only be the part interface fault of MGW or opposite equip., for all online callings do not exert an influence to this equipment office direction, so can only remove a part of online calling according to pre-configured calling control ratio, a perhaps control part is called out and is inserted, and needn't forbid the all-calls of this equipment office direction.
After the part of the described equipment office direction of control is called out, if still have the ID of this office direction equipment of fault correspondence to report, the ratio that inserts according to pre-configured increase controlling call then, for example, allocation ratio is set to 5%, then whenever receive on the ID of this office direction equipment of fault correspondence and give the correct time, just increase the ratio that 5% controlling call inserts.
The technical scheme of being put down in writing from call Cut-in control method embodiment one as can be seen, owing to pass through BFD, PING etc. and call out that irrelevant detection technique detects and opposite equip. between carrying fault whether, therefore, can be before certain calling or all-calls start detection mechanism, and reporting that detection is obtained with carrying fault corresponding equipment ID, and and then according to the device id that reports, the calling access control is carried out in calling between the pairing equipment office direction of device id, therefore can before certain calling or all-calls, carry out and call out access control, so can avoid influencing the voice quality of existing call.
Call Cut-in control method embodiment two:
With reference to Fig. 4, flow chart for call Cut-in control method embodiment two in the embodiment of the invention, be with embodiment one difference, corresponding equipment ID when the fault message that MGW reported not only comprises carrying fault with opposite equip., in the time of also will reporting fault simultaneously and the bearer capability information that carries between this opposite equip., and the MSC server is carried out and is called out access control according to the pairing device id of fault and the bearer capability information that report, below is elaborated by concrete steps:
41, MGW starts and calls out irrelevant detection technique, detect and the opposite equip. office direction between carrying fault whether;
MGW can detect whether fault of this equipment by the testing mechanism of self, and adopt BFD, PING etc. and call out that irrelevant detection technique detects and the opposite equip. office direction between carrying fault whether, concrete detection method identical with described in the call Cut-in control method embodiment one repeats no more.
42, when detection obtain and described opposite equip. office direction between the carrying fault time, inquiry fault pairing device id, and this equipment office direction between bearer capability information;
When adopt BFD, PING etc. some with call out that irrelevant detection technique detection obtains and opposite equip. between the carrying fault time, fault message table according to the MGW configuration, the bearing capacity of inquiring about pre-configured interface accounts for the ratio of the total bearing capacity between this equipment office direction, gather, obtain the bearing capacity loss ratio between this equipment office direction that each interface fault causes.With reference to table 2, be the fault message table of MGW configuration.
| Device id | Device attribute | IP address of equipment | This interface accounts for total bearing capacity ratio (%) |
| 0 | The opposite end | IP0 | 10％ |
| 0 | The opposite end | IP1 | 10％ |
| 0 | The opposite end | IP2 | 20％ |
| 0 | The opposite end | ... | ... |
| 0 | The opposite end | IPn | N％ |
| 1 | The opposite end | IP0 | 10％ |
| 1 | The opposite end | IP1 | 10％ |
| 1 | The opposite end | IP2 | 20％ |
| 1 | The opposite end | ... | ... |
| 1 | The opposite end | IPn | N％ |
| ... | ... | ... | ... |
| N | Itself | IPm1 | 10％ |
| N | Itself | IPm2 | 20％ |
| N | Itself | ... | ... |
| N | Itself | IPmN | N％ |
Fault message table 2
When detection obtains the BFD link failure of certain IP address, inquire about this table and can obtain this IP address corresponding equipment ID, and the device attribute of this equipment and each interface accounts for the ratio of total bearing capacity, wherein, opposite equip. is represented in the opposite end, and itself represents MGW self.Account for the ratio of total bearing capacity according to each interface of this equipment, can obtain the bearing capacity of this equipment, for example the bearing capacity ratio of Shi Ji bearing capacity ratio or loss.For example, in the fault message table 2, if device id is 0 IP0, IP1, the interface or the link failure of IP2 correspondence, the bearing capacity of equipment loss is the 10%+10%+20%=40% of total bearing capacity, and the bearing capacity of real surplus then is 60% of total bearing capacity.
43, with the fault information reportings such as device id, device attribute and bearing capacity relevant information of this equipment to the MSC server;
Actual bearer ability when the bearing capacity relevant information that reports can be for fault, also the bearing capacity loss ratio that can cause for fault.
The fault corresponding equipment ID that inquiry is obtained, and this equipment office direction between the bearing capacity relevant information be reported to the MSC server.Specifically can be by packet protocol is H.248 expanded realization:
For example, the lossper reporting events that can define ntbdet bag is given the bearing capacity relevant information between MSC server and this equipment, and passes through DevID attribute instruct MS C server opposite equip. ID.The Notify information reporting of MGW structure Mc interface is given the MSC server, and the MSC server just can be known the equipment that certain is specific like this, and how many bearing capacitys descended.
The concrete definition of ntbdet bag can be:

Wherein, the bearing capacity loss percentage that reports is total interface bearing capacity loss ratio sum in this specific opposite equip..Certainly, the actual bearer ability ratio sum of the total interface of this particular device in the time of also can reporting fault.
44, the MSC server according to the fault corresponding equipment ID that reports, with this equipment between the bearing capacity relevant information, to and described opposite equip. office direction between calling carry out the calling access control.
The MSC server according to the device id that reports and with this equipment between bearer capability information, the online calling of the subsequent voice calls of control preset proportion or dismounting preset proportion.For example, certain equipment can allow 1000 to call out simultaneously online at most, current online calling has 800, if fault causes and this equipment between the bearing capacity of carrying descend 50%, then can only allow 500 to call out simultaneously online at most, therefore, remove 300 online callings, control the access of subsequent voice calls simultaneously.If this equipment can allow 1000 to call out simultaneously onlinely at most, current online calling has 800, if fault causes and this equipment between the bearing capacity of carrying descend 10%, then can also insert 100 callings at most, so when subsequent voice calls surpassed 100, then refusal inserted.
When and certain equipment between carrying when breaking down, in order to guarantee the communication of some important call, can remove the lower online calling of priority according to call priority.Specifically can adopt Leaky Bucket algorithm: in advance according to the total capacity of the IP bearing capacity of office direction, divided by rule of thumb or estimation obtain every road and call out the bandwidth of occupying, be Mi thereby obtain the maximum calls of supporting of this equipment office direction.The current online calls of this equipment office direction is Wi, and the service bearer loss ratio that reports is Ni%, then as Wi＜Mi* (1-Ni%), does not do the controlling call access control; When Wi=Mi* (1-Ni%), start Leaky Bucket algorithm, the calling of follow-up override capability is controlled; As Wi〉during Mi* (1-Ni%), remove the lower user's of some priority calling according to call priority, concrete calls is: Wi-Mi* (1-Ni%), and the access of control subsequent voice calls.
From this embodiment as can be seen, because the bearing capacity of reality when bearing capacity relevant information that can report according to MGW and described opposite equip. is learnt described device fails, thereby can keep the online calling of determining ratio, guarantee the voice quality of existing call, thereby can avoid the all-calls of this equipment office direction is exerted an influence.
In fact, because when the bearing capacity of certain interface descends, if the bandwidth redundancy ratio of other interfaces is sufficient, and can take over the business of this interface, may not can cause the decline of bearing capacity, therefore, if certain port failure can not bring the corresponding business bandwidth loss, then do not report; If can bring the corresponding business bandwidth loss, then inquire about the computation rule of bandwidth loss, all there is not the bandwidth redundancy such as each interface, rule herein is " equal this interface and account for total bearing capacity ratio (%) ".Other situations have the corresponding calculated rule.Finally can obtain: because the traffic lost that this link failure correspondingly causes accounts for the IP bearing capacity ratio of this equipment office direction by calculating.With reference to fault message table 3.

Fault message table 3
In above-mentioned two embodiment, when MGW adopt with call out irrelevant detection technique detect obtain and opposite equip. between the carrying recovery just often, MGW can report the recovering information of correspondence, for example report corresponding equipment ID, perhaps the bearing capacity of corresponding equipment ID and corresponding device office direction is recovered ratio, specifically still can realize by the H.248 bag of above-mentioned expansion, the bearing capacity change information that lossper attribute by ntbdet bag reports and realize with the indicated device id of DevID attribute, when the pairing bearing capacity of the device id that reports when the MSC discovering server is recovered, reduce the ratio or the call disestablishment access control of controlling call access control.In call Cut-in control method embodiment two, can reduce the ratio of controlling call access control by Leaky Bucket algorithm, be not described in detail.
Call Cut-in control method embodiment three:
With reference to Fig. 5, flow chart for call Cut-in control method embodiment three in the embodiment of the invention, be with the difference of above-mentioned two embodiment, when MGW detect and certain opposite equip. between the carrying fault time, only will carry the IP reporting address of place interface correspondence, and in the MSC server, dispose the corresponding relation of IP address and fault message, the IP address can be the IP address of opposite equip., also can be the IP address of MGW itself.The MSC server is according to submitted IP address, and the fault message that inquiry is corresponding, and call out access control according to the described fault message that inquiry obtains below is elaborated by concrete steps:
51, MGW starts and calls out irrelevant detection technique, detect and the opposite equip. office direction between carrying fault whether;
MGW can detect whether fault of this equipment by the testing mechanism of self, and adopt BFD, PING etc. and call out that irrelevant detection technique detects and the opposite equip. office direction between carrying fault whether, concrete detection method identical with described in above-mentioned two embodiment is not described in detail.
52, when detection obtain and described opposite equip. between the carrying fault time, MGW with the pairing IP reporting address of fault to the MSC server;
MGW can be by expansion H.248 agreement with the IP reporting address of described fault correspondence to the MSC server, similar with embodiment one, difference is, comprise equipment corresponding equipment ID in the fault message that reports among the embodiment one, comprise the IP address of fault correspondence in the fault message that reports in the present embodiment.
53, the MSC server is inquired about the pairing equipment office direction of fault according to the pairing IP of the fault address that reports;
At the fault message table that disposes the corresponding relation between expression IP address and bearing capacity, the office direction number on the MSC server, with reference to fault message table 4.
