Background technology
Along with the develop rapidly of packet network, Media Gateway Controller (Media Gateway Controller, MGC) and media gateway (Media Gateway MG) has become two key members in the packet network.As shown in Figure 1, be MG among the prior art NGN and MGC networking schematic diagram.MGC is responsible for CCF, and MG is responsible for the service bearer function, realize by this calling out separating of control plane and service bearer plane, thus abundant shared network resource, simplified apparatus upgrading and professional expansion reduce development and maintenance cost greatly.MGCP is the main agreement of communicating by letter between MG and the MGC, and H.248/MeGaCo at present widely used have and two kinds of agreements of MGCP.
" IPTV QoE " (IPTV Quality of experience) is meant that video traffic satisfies the degree of users' expectation, is to be related to the professional key of success key element of IPTV.
Usually, the characteristic of Network Transmission can reduce three indexs: postpone shake and packet loss.The IPTV number of users increases and behavior, and the fusion of other triple play flow of contention finite element network resource, all can produce significant impact to promptness and the accuracy that the IPTV packet is transmitted.The Network Transmission fault that causes thus (comprising data-bag lost and sequence errors, delay variation etc.) can be brought in various degree harmful effect to video quality, as mosaic, image blurring, edge distortion, (picture sudden change) and visual noise etc. tremble.
In order to reflect that IP transmission network damage is to the influence of IPTV media quality and the effective evaluation network equipment tenability to the IPTV business, IETF RFC4445 standard definition media transmission quality index (MediaDelivery Index, MDI), on network layer, weigh the user video Quality of experience of expection.(Media Loss Rate MLR), and evaluates and tests the media flow transmission performance according to DF and MLR the MDI Loss Rate.What the DF value was expressed is the spacing value that each packet is shown or signs in test point.MLR has provided the quantity or the out-of-sequence quantity of data packets of data-bag lost in the selected time interval.MDI is not subjected to the influence of media coding scheme, is independent of various host-host protocols and streaming encapsulation protocol, is a kind of simple, extendible measurement scheme, can substitute the method for measurement that medium (audio frequency and video) itself are decoded and checked to a certain extent.
MDI can be used for locating and characterizing the network failure that media quality and user's Quality of experience is caused adverse effect.If the intermediate point at transmission network is followed the tracks of MDI, then the difference of MDI index between the contiguous network element can help to isolate rapidly potential problem or the damage that has existed.If the medium Loss Rate of the previous dive in the IPTV data flow path (Hop) is zero, and through having introduced a bigger medium Loss Rate behind certain network carrying equipment (as gateway or router), there is performance issue in this with regard to obviously showing in this equipment, and for example buffer overflows or packet are destroyed.Equally, if the variation of retardation coefficient in two are jumped continuously (Hop) is very obvious, expression causes the queue delay of length owing to packet is congested, but this situation imminent data-bag lost of early warning also.
As the industry standard of IP video flowing transmission quality test, the MDI measurement index is adopted by IP video quality alliance (IPVQA), is widely used in IPTV and network quality evaluation of IP Cable Network and monitoring.
Therefore serve as carrying entity on the media flow transmission path as MG, when reception and/or forwarding media data, in order to realize that network is to media flow transmission service quality detection end to end and guarantee, and the effective evaluation gateway device is to the tenability of IPTV business, MG is necessary the MDI index of media flow transmission is followed the tracks of timely and collected, and prevents generation, the guarantee media transmission quality of network failure in advance.But, also lack effective mechanism in the present media gateway related protocol and can support the demand.

Embodiment
For making technical scheme of the present invention clearer, below with reference to accompanying drawing and enumerate embodiment, the present invention is described in more detail.
In order to make MGC and MG can support and utilize the MDI index, need expand MGCP.
At first, in order to realize that MGC to the monitoring that MG goes up media transmission quality, expands a statistics (Statistic) parameter, in order to the MDI index of indication media transmission quality.
For example with this statistical parameter called after " media transmission quality index (Media Delivery Index is abbreviated as mdi) ".This statistical parameter can belong to an existing or bag (Package) newly developed.The content of mdi parameter is as the definition among the RFC 4445, and (Delay Factor is df) with medium Loss Rate (Media Loss Rate, mlr) two parts to comprise retardation coefficient.
The type of this statistical parameter is character string (String), and form can be identical with the MDI form of RFC 4445, i.e. df:mlr.For example: " mdi=3.25:0.02 " represents the time delay coefficient of Media Stream is 3.25 milliseconds, and the medium frame loss rate was 0.02 frame/second.
The df of statistical parameter mdi is a time value, and its representative data wraps in the spacing value that gateway node is shown or signs in, and the buffer of expression MG must comprise the data of how many milliseconds could eliminate shake, and concrete computational methods are seen RFC 4445.But whether the retardation coefficient reflecting video image fault can occur, thereby obtains user's Quality of experience on certain aspect.Retardation coefficient also can be determined the influence that single network element produces in the video flowing transmission path.Whether the df of the df by relatively flowing into equipment and the equipment of outflow injects the transmission that too much shake influences video to such an extent as to can determine this equipment.
The mlr of statistical parameter mdi can be defined as media data packet loss (or improper) quantity of data packets in the selected time interval, and be 1 second selected usually blanking time, and concrete computational methods are seen RFC4445.Detection to improper packet is extremely important, because the often not packet rearrangement to receiving of many equipment in the network, and directly send it to decoder.Any data-bag lost (when non-zero mlr promptly occurring) all can bring adverse effect to video quality, and causes vision distortion or unusual and uneven video playback.
This statistical parameter can be applied in terminating stage or stream (Stream) level.In the time of on being applied to MG or certain particular terminal, then this parameter representative is the quality index of all media flow transmission on this MG or the terminal; And when being applied on certain specific stream, then representative is the transmission quality index of this Media Stream.
The audit of MGC by MG is gone up the mdi statistical parameter can in time obtain the media transmission quality indication information that MG goes up media flow transmission, ensures so that reach real-time monitoring and QoE.Equally, when the real time monitoring network operation situation, MGC can be in conjunction with the method for statistical report in H.248.47, can be mdi statistical parameter (df, mlr) preset certain threshold value, in case MG detects the value of mdi and is below or above this threshold value, then to MGC report dependent event, so that MGC in time grasps the various abnormal conditions in the Network Transmission.
Certainly, also two contents among the above-mentioned statistical parameter mdi can be split into two independently statistical parameters: retardation coefficient (Delay Factor, df) and the medium Loss Rate (Media Loss Rate, mlr).Wherein, the type of parameter d f is the Double type, and unit is a millisecond (ms); The type of parameter m lr is the Double type, and unit is the media data packet loss number of per second.The implication of described two statistical parameters is described with the front, and its application is identical with front statistical parameter mdi.
Secondly, in order to utilize MDI index realization MGC and MG control to bearing resource, ensure the transmission quality of Media Stream, according to same inventive concept, expand an attribute (Property) parameter, MDI index (promptly ensureing the MDI index in order to indication) in order to indication guarantee media transmission quality requires MG to reserve corresponding bearer resource for this reason.
For example with this property parameters called after " request media transmission quality index (Request MediaDelivery Index is abbreviated as rmdi) ".This statistical parameter can belong to an existing or bag (Package) newly developed.The content of rmdi parameter can comprise retardation coefficient, and (Delay Factor, df) (its definition is described with front statistical parameter mdi for Media Loss Rate, mlr) two parts with the medium Loss Rate.
MGC gives MG by issuing the rmdi attribute, and indication MG reserves relevant bearing resource according to the MDI index that comprises in the described property parameters, prevents the generation of gateway fails, ensures the transmission quality of Media Stream.
Certainly, also two contents among the above-mentioned property parameters rmdi can be split into two independently property parameters, for example with these two property parameters difference called afters: request retardation coefficient (Request DelayFactor, rdf) and request medium Loss Rate (Request Media Loss Rate, rmlr), its definition is described with front statistical parameter df and mdi.
Simultaneously for to realize that H.248 agreement is to the support of media transmission quality index MDI, can define a new H.248 bag, for example with this statistical parameter called after " media transmission quality index monitoring (Media Delivery Index Monitor is abbreviated as mdim) bag ".Wherein, can comprise aforesaid attribute and statistical parameter.By the realization to this bag, on the one hand, MGC and MG can be by the quality index information in tracking in time of described statistical parameter and the collection media flow transmission; On the other hand, MGC can effectively control the bearing resource on the MG by described extended attribute, so that various in the Network Transmission are monitored unusually in real time and prevent, thus network enabled transmission quality guarantee end to end effectively.
Below by concrete scene the embodiment of the invention is further introduced.
See also Fig. 2,, comprise the steps: for using the monitoring flow process of the MDI index that the embodiment of the invention realizes
Step 1:MGC is when creating terminal or increase stream (as issuing Add order or Modify order), the mdi statistical parameter is indicated to MG, require statistics media transmission quality indication information, this media transmission quality indication information is embodied as retardation coefficient and the medium Loss Rate that MG goes up carrying media.
Step 2:MG responds the request indication of MGC, and begins related media transmission quality indication information (comprising retardation coefficient df and medium Loss Rate mlr) is collected and added up.
The concrete grammar that MG detects and calculates the mdi index repeats no more referring to RFC 4445 herein.
Step 3:MGC passes through the value condition that audit value (AuditValue) request message audit MG goes up statistical parameter mdi (or df and mlr), so that the media transmission quality on the MG is in time understood.
As previously mentioned, the audit of statistical parameter can be applied to certain terminal on the MG or specific stream.When upward certain specific terminal was audited to MG, the form of its request message can be as follows: (for example needing the terminal A5556 on the MG is audited):

Transaction＝50006{
Context＝5000{
AuditValue＝A5556{
Audit{
Statistics{mdim/df，mdim/mlr}
}
}
}
}
When MG being gone up certain specific stream audit, the message format of audit value request message can be as follows (for example needing that terminal A5556 upper reaches is designated 2 stream audits):
MEGACO/3[123.123.123.4]:55555
Transaction＝50007{
Context＝5000{
AuditValue＝A5556{
Audit{
Media{
Stream＝2{
Statistics{mdim/df，mdim/mlr}
}
}
}
}
}
}
Step 4:MG as the media transmission quality indication information, reports MGC by the audit value response message with detected retardation coefficient df and medium Loss Rate mlr.
The request message of corresponding front, the answer message form (the terminal A5556 on the MG is audited) as follows of terminating stage statistics:
MEGACO/3[125.125.125.111]:55555
Reply＝50006{
Context＝5000{
AuditValue＝A5556{
Statistics{
mdim/df＝3.25，
mdim/mlr＝0.02
}
}
}
}
The answer message form of specific stream statistics (terminal A5556 upper reaches is designated 2 stream audit) as follows:
MEGACO/3[125.125.125.111]:55555
Reply＝50007{
Context＝5000{
AuditValue＝A5556{
Media{
Stream＝2{
Statistics{
mdim/df＝3.25，
mdim/mlr＝0.02
}
}
}
}
}
}
Step 5, MGC receive the media transmission quality indication information that MG reports, if the media transmission quality indication information that discovery receives and the MDI desired value of expectation are not inconsistent, determine resource policy (as formulating new resource policy, the existing resources strategy being adjusted or kept), the resource policy of the media transmission quality index that is protected according to the media transmission quality index of expectation.
This step can be by analyzing the MDI index of expectation, generation ensures the property parameters (is example with request media transmission quality index (rmdi)) of MDI index in order to indication, it is carried in the adjusted resource policy is handed down to MG, require MG to carry out corresponding resource allocation and adjustment.
Step 6, MG analyze the media transmission quality index rmdi that carries in the described adjusted resource policy, draw and to reach these index resource needed parameters (as bandwidth, buffering, shake etc.), carry out corresponding resource allocation and adjustment according to this resource parameters, and send response message to MGC.
Pass through said method, MG just can detect the MDI index according to the request of MGC, and testing result reported MGC, make MGC can go up the situation of change of media transmission quality according to MG, in time adjust the strategy of network control, prevent contingent network failure, to ensure Media Stream reliable transmission end to end.Need to prove, this embodiment also can directly be provided with threshold value (this threshold value is the MDI value of expectation) on MG, when MG detects the MDI index and is below or above this threshold value, report to MGC, MGC directly carries out the adjustment of resource policy according to the MDI value of expectation.Simultaneously, MGC carries out the resource policy adjustment according to the MDI value of expectation, also can directly be analyzed the MDI value of expectation by MGC, draws and will reach these index resource needed parameters, determine the resource policy adjustment according to this parameter value, the resource policy of determining is handed down to MG carries out.
