Description
Technical field
The present invention relates to communication field, more particularly, relate to a kind of IP bearing network service quality control method and system.
Background technology
Variation along with development of telecom technology and user's request, with NGN, 3G, Triple-play is representative, the pattern of multiple business such as integrated voice, video, Streaming Media makes personalized more, the mediumization more of following means of communication, and the characteristic that the IP technology relies on itself and bearing medium to have nothing to do becomes the first-selection of unified bearer network.For example can by the multi-service IP network connect PSTN/ISDN, ATM, DDN, X.25, networks such as ISP/ICP, LAN/WAN, thereby carry out the access of voice, data, image, multimedia etc.
The new business that emerge in large numbers fast, scale lays has proposed strict or even harsh requirement to the IP bearer network, and current IP network lacks and supports the key feature that the carrier class business is carried out: for example can run can manage, multi-service support, service quality assurance, service security problem etc.When the load of the router in the IP bearer network exceeds the predetermined process ability, the service quality of whole system (QOS) will sharply reduce, and this is a very fatal weakness of IP bearer network.So guarantee the service quality of entire I P bearer network if desired, must manage control to the service quality of IP bearer network.
At the problems referred to above, adopt IP Telecommunication Network usually at present.This IP Telecommunication Network advanced technology, multiple functional, but the technology more complicated of its realization, cost is higher.
Carry out the control of IP bearer network by the mode of UMG (Universal Media Gateway) perception RTP (real time data stream) quality in addition in addition.As shown in Figure 1, in this system, by the RTP quality between media gateway (for example UMG) 12 monitoring business aspects and bearer network, wherein service layer comprises service control point (for example soft switch or service server) 11, and bearer network is made of core router 14 and edge router 13.Yet in this system, when the load of router is declaring that in the index, bearing capacity is normal fully, declare index and in a single day surpass, its service quality can sharply descend, and causes this system can not avoid the problem generation fully like this.

Embodiment
As shown in Figure 2, in one embodiment of the invention, the IP bearer network includes router two 3, media gateway 22 and the service control point 21 that connects successively, wherein 21 of media gateway 22 and service control points be by protocol interaction H.248, then can be connected by general-purpose interface or special-purpose RU (for example this interface is the 40/42/Mb interface in the 3GPP2 agreement) interface between router two 3 and the media gateway 21.In the present embodiment, router two 3 includes core router and edge router.
In the present embodiment, router two 3 (edge router) includes carrying disposal ability information is sent to the sending module 231 of service control point 21 via media gateway 22, and media gateway 22 include the bearing capacity process information from router is encapsulated into notification message (Notify) H.248 and will encapsulate after notification message send to the package module 221 of service control point 21.Service control point 21 includes the Service Processing Module 211 of control quality of service, and it is according to carry out the traffic carrying capacity regulation and control from the carrying disposal ability information of router.
In the present embodiment, the service control point 21 that is arranged in key-course can be the soft switch of next generation network (NGN).In addition, Service Switching Point 21 also can be the service server in the intelligent network.
As shown in Figure 3, be the flow chart of IP bearing network service quality control method of the present invention.In the present embodiment, the IP bearer network includes router two 3, media gateway 22 and the service control point 21 that connects successively, and described service control point 21 has the module of control quality of service.
Step S31, router two 3 will carry disposal ability information and send to service control point 21 via media gateway 22.In the present embodiment, router two 3 at first will carry disposal ability information and send to media gateway 22 via the interface of 22 of router two 3 and media gateway; Media gateway 22 is encapsulated in H.248 notification message with the carrying disposal ability information of its reception then, and the notification message after will encapsulating sends to service control point 21.In the present embodiment, above-mentioned carrying disposal ability information comprises the current actual bandwidth of router two 3 and CPU disposal ability etc.
Step S32, described service control point 21 is according to the carrying disposal ability information that receives, flow control strategy by himself carries out traffic carrying capacity regulation and control (for example reducing the call voice encoding quality), thereby entire I P bearer network is in one or the higher service state accepted all the time, and guarantees that the IP bearer network is unlikely to overload.
Owing to the variation along with traffic carrying capacity of the actual bandwidth of router two 3 changes, therefore in order to guarantee the utilance of IP bearer network, router two 3 can regularly carry the disposal ability information interaction with service control point 21, be that router two 3 regularly reports carrying disposal ability information to service control point 21, thereby make service control point 21 carry out the traffic carrying capacity regulation and control according to carrying disposal ability information in real time.
As shown in Figure 4, carry out once mutual data flowchart for router two 3 and service control point.At first router will carry disposal ability and be reported to media gateway 22, and the carrying disposal ability information that media gateway 22 will receive is encapsulated in H.248 notice (Notify) message and reports service control point 21.Service control point 21 returns H.248 push-notification-answer message to media gateway 22 receiving H.248 the notice back, and media gateway 22 is returned carrying disposal ability response message to router two 3.Router two 3 carries out mutual next time in the scheduled time after receiving carrying disposal ability response message again.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
