Embodiment
In order to be implemented in the call proceeding that telephone traffic satisfies high-priority users and urgent call when big, the embodiment of the invention provides a kind of corresponding call method for limiting and call blocking device.
Below in conjunction with accompanying drawing, call limitation method provided by the invention and call blocking device are described in detail.
Referring to Fig. 1, the call limitation method flow chart for the embodiment of the invention provides comprises the steps:
Step S101, receipt of call request;
Step S102, judge whether the current resource utilization of IAD reaches the threshold value of setting, if, execution in step S103, otherwise, go to step S105;
Step S103, determine whether this calling is the important call that need continue, if, go to step S105, otherwise, execution in step S104;
In the practical application, can set in advance the important call that need continue:
For example: set in advance the telephone number of important call correspondence, only receive the calling that the telephone number of the important call that belongs to setting initiates or called out, being defined as is the important call that need continue;
For example: User Priority is set, and the user be higher than a certain priority is set is responsible consumer, when responsible consumer made a call or called out, being defined as was the important call that need continue;
For example: the special number table is set, and storage is used for the special number of urgent call; When the calling that receives is that being defined as is the important call that need continue when calling out the urgent call of special number;
Step S104, refuse this calling, flow process finishes;
Step S105, execution call proceeding, flow process finishes.
In the practical application, a switch that whether starts the call blocking function can also be set, closing or opening of this switch can be provided with by manmachine command by the system maintenance personnel.If close this switch, then carry out the normal call flow process; Heavy or in particular cases when system loading at some, open this switch by manmachine command, start the call blocking function.
If start call blocking (aftermentioned is called for short " limit is exhaled "), need set in advance the resource utilization threshold value of each resource of IAD, after receiving call request, calculate the current utilization rate of each resource of IAD, compare with the corresponding utilization rate threshold value of setting with the current utilization rate that calculates.
For IAD, have various resource distributions, in the call proceeding process, the resource relevant with call proceeding all needs to start and use.Wherein, characterize the index of IAD resource utilization, for example:
CPU usage: call out under the situation about taking place a large amount of, CPU usage often all can be very high in the IAD, if do not limited, CPU usage can reach 100% under extreme case.When the CUP of IAD occupancy is high, be certain to influence speech quality, the user in communication process may feel that conversation is intermittent, the user who is calling out then can feel to be difficult to connect or connect too slow.In some cases, in addition urgent call all can't be successful as dialing 110.Therefore, the CPU usage of IAD can not be too high, and a corresponding utilization rate threshold value need be set.It is 80% that CPU usage for example is set.
The IAD port speed: present accessing gateway equipment not only provides narrow band service, also can provide broadband service.And the external Ethernet interface of actual accessing gateway equipment can not be too many, generally speaking, the ethernet address of distributing to an accessing gateway equipment is also with regard to 1 to 2, and Ethernet interface speed generally all is 100,000,000 or gigabit speed at present, exceed this speed, may produce packet loss, influence quality of service.So the external ethernet port speed of IAD also is to carry out the important indicator thresholding that call blocking needs reference.
The various resource utilizations relevant: utilization rate such as RTP channel resource, sound resource for example with call proceeding.Put (but because these resource dynamic assignment and recovery, full configuration is put and will inevitably be caused great waste) because these resources generally can not carried out full configuration according to number of users, thus actual number of resources than number of users lack many.If but under extreme case, with there being a large amount of the calling constantly, resource all can be used up.The consequence of this situation also can cause follow-up important urgent call can't connect because of resource shortage.Therefore, also need in call blocking, consider.
Above-mentioned various resource utilization, only for for example, the present invention does not limit the utilization rate of which resource that IAD specifically is set.
In the inventive method, by setting in advance each resource utilization threshold value of IAD, when reaching the threshold value of setting, only the responsible consumer (high-priority users) or the urgent call of calling out special number (as 110,119 etc.) are carried out call proceeding, promptly use the outer part resource of reserving of threshold value to be responsible consumer or emergency call service.For the non-emergency call of other domestic consumer, then temporary transient startup limit is exhaled, and is depleted with the resource of avoiding IAD.
In the inventive method,, then when the utilization rate of this resource reaches the threshold value of setting, start limit and exhale if only be provided with a kind of utilization rate of resource.If be provided with the corresponding utilization rate of two or more resource, then start and limit the condition of exhaling to be provided with flexibly, for example can be set to:
Have only when wherein the utilization rate of any resource reaches the threshold value of setting, just start limit and exhale;
When perhaps the utilization rate of a part of resource of She Zhiing reaches the threshold value of setting, start limit and exhale;
When perhaps the utilization rate of whole resources of She Zhiing all reaches the threshold value of setting, just start limit and exhale.
Adopt the inventive method, provide service guarantee, satisfy its percept of call completed responsible consumer.In the practical application, can store subscriber directory number and responsible consumer mapping table in advance, after receiving call request, obtain the caller of this calling or called telephone number, the subscriber directory number and the responsible consumer mapping table of inquiry storage determine whether the calling/called user of this calling is responsible consumer.At this, can divide the grade of different rights of using to the user by operator according to the requirements of different users situation, as be divided into VIP user and domestic consumer.If VIP user, then when the AG internal resource reached set thresholding, preferentially the outer reserved resource of usage threshold continued the normal call flow process, reaches better call completion ratio; If domestic consumer, then need to judge item by item the available situation of each resource.
Simultaneously, the present invention also guarantees percept of call completed for the urgent call of domestic consumer as far as possible.Because in a lot of occasions, the telephone subscriber has the demand that asks for help as special numbers such as 110,119,120 of dialing.According to call limitation method provided by the invention, to all kinds of valuable sources of IAD a corresponding utilization rate threshold value can be set all, in the threshold value of setting, taking of each resource is generally less than its peak load.When domestic consumer initiated urgent call, if resource utilization reaches threshold value and do not exceed its busy hour, can utilize surplus resources was that call proceeding is carried out in the urgent call of this domestic consumer.If but domestic consumer's calling is common number, under the situation of resource scarcity (being the threshold value that resource utilization reaches setting), allow it temporarily listen busy tone to wait for that other users discharge resource.Domestic consumer may attempt after hearing busy tone once more, and this moment, other users might finish conversation, had discharged resource.This time majority for the user of no urgent need, also can be tolerated in 10 seconds.
In the practical application, can store the special number table in advance, storage is used for the corresponding special number of urgent call in this special number table, as 110,119,120 etc.After receiving call request, obtain the called number of this calling, the special number table of inquiry storage if called number is one of special number of storing in the special number table, determines that then this calling is urgent call, and carries out call proceeding for this urgent call.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, this program can be stored in the computer read/write memory medium, as: ROM/RAM, magnetic disc, CD etc.

Calculate the current resource utilization of IAD, for example: calculate the utilization rate of the central control unit CPU of IAD, calculate the port speed of IAD, calculate the utilization rate of access-in resource relevant in the IAD etc. with call proceeding.Judge whether the current resource utilization of IAD reaches the threshold value of setting,, show then that IAD is current and also have more resource available, do not need to start limit and exhale if do not reach the corresponding threshold value of setting; If reached the corresponding threshold value of setting, then need to start limit and exhale.Concrete limit exhales strategy to be:
Obtain the calling number of this calling, the subscriber directory number and the responsible consumer mapping table of the local storage of inquiry determine whether the calling subscriber of this calling is responsible consumer, if then need call proceeding is carried out in this calling; And
Obtain the called number of this calling, the special number table of the local storage of inquiry if called number is one of special number of storing in the special number table, determines that then this calling is urgent call, need carry out call proceeding to this calling;
Other situation is all refused to call out.
The callee side flow process is:
1, the callee side IAD is received the increase context that soft switch issues;
2, IAD determines whether to start limit and exhales after receiving the increase context.
3, limit if desired and exhale, then to soft switch response failure; Otherwise respond successfully.
Callee side determines whether to need to start to limit the concrete grammar of exhaling to comprise:
Calculate the current resource utilization of IAD, for example: calculate the utilization rate of the central control unit CPU of IAD, calculate the port speed of IAD, calculate the utilization rate of access-in resource relevant in the IAD etc. with call proceeding.Judge whether the current resource utilization of IAD reaches the threshold value of setting,, show then that IAD is current and also have more resource available, do not need to start limit and exhale if do not reach the corresponding threshold value of setting; If reached the corresponding threshold value of setting, then need to start limit and exhale.Concrete limit exhales strategy to be: obtain the called number of this calling, the subscriber directory number and the responsible consumer mapping table of the local storage of inquiry determine whether the called subscriber of this calling is responsible consumer, if then need paging called; Otherwise the refusal paging is to soft switch response failure.
