Embodiment
With reference to the accompanying drawings specific embodiments of the invention are described.
Referring to Fig. 1, when MGW carrying packet traffic flows, can cause the service quality variation of the Packet Service that carries between MGW1 and MGW2 owing to reasons such as MGW inadequate resource, data bandwidth deficiency, data damages.Therefore the present invention can the service quality to packet traffic flows monitor on MGW, and monitoring result is reported on the coupled MGC, by MGC the flow of the Packet Service that this MGW carried is controlled.
Fig. 2 is the flow chart of in flexible exchanging network Packet Service being handled of the present invention.Referring to Fig. 2, this flow process comprises:
Total QoS parameter of the packet traffic flows that step 201, MGW monitoring are carried;
In this step, MGW can monitor the service quality of all service channels of being carried; Perhaps, only the service quality of the partial service passage that carried is monitored, herein, because MGW can (comprise that this MGW ownership MGC has jurisdiction over other interior MGW with a plurality of other MGW, and this MGW ownership MGC has jurisdiction over other MGW outward) communicate and to form MGW right, this MGW may carry a plurality of Packet Service passages with each MGW centering that other MGW form, so can monitor 1～N service channel in a plurality of service channels that each MGW centering carried herein, wherein N is the integer more than or equal to 1; As for concrete which service channel of monitoring, can determine that is: when a service channel inserted, MGC sent the quality of service monitor order by the Hc interface to MGW by MGC, indication MGW monitors this service channel; Perhaps the service channel that need monitor is determined voluntarily by MGW, need to be about to the service channel sign of monitoring to be pre-configured among the MGW.
Herein, the content that the service quality of each service channel of need monitorings is monitored is: to the QoS parameter of service channel, for example: the effective bandwidth of packet loss, time-delay, shake, Packet Service or aforementioned four combination in any are monitored and record at any time; Wherein, MGW can receive that effectively clean byte number of words represents the effective bandwidth of described Packet Service by record.The method of concrete monitoring frame loss rate, time-delay, shake, effective bandwidth can adopt existing known monitoring method, repeats no more herein.
In order to determine total QoS parameter of packet traffic flows, need sample to the QoS parameter of each service channel of being monitored, total QoS parameter of the packet traffic flows service quality situation that obtains to reflect that this MGW carries, comprising overall packet loss, time-delay, shake or effective bandwidth, the concrete method of sampling can adopt existing technology, for example can adopt the disclosed method of sampling among the IETF RFC3550.
In the present embodiment packet traffic flows being monitored and carried out flow restriction all is at each MGW the packet traffic flows of being carried to be carried out.So total QoS parameter herein is meant the total QoS parameter of a MGW to the Packet Service that carried.
To the report of MGC reporting service quality, this service quality report adopts the form of Hc interface message, comprising the monitoring result of step 101 by the Hc interface for step 202, MGW.
A kind of herein concrete mode that reports is regularly to report: preset timer in this MGW reports service quality report according to pre-set time interval one time at each timing cycle.
The another kind of concrete mode that reports is to trigger to report, also can be called the alarm mode: the threshold value (the quantization threshold value of packet loss, time-delay, shake for example can be set) of default total QoS parameter of being monitored in this MGW, and the total QoS parameter that will monitor in real time threshold value corresponding with this parameter compares, when the parameter of the service quality of being monitored arrives its corresponding threshold value, then judge current service quality variation, the report of triggering reporting service quality is to alarm to MGC.Threshold value herein can be one, also can be a plurality of graduate threshold values, it is the service quality rating threshold value, when the service quality of monitoring arrives in the scope of some threshold values, then trigger the service quality report that reports corresponding grade, wherein carry corresponding with service credit rating information, promptly alarm class information; For example: the service quality alarm level can be divided into a 0-5 grade according to the packet loss in total QoS parameter, that is:
0 grade of alarm: 0%＜packet loss＜2%;
1 grade of alarm: 2%＜packet loss＜8%;
2 grades of alarms: 8%＜packet loss＜25%;
3 grades of alarms: 25%＜packet loss＜45%;
4 grades of alarms: 45%＜packet loss＜75%;
5 grades of alarms: 75%＜packet loss＜95%.
Obviously, the present invention also can be divided into a plurality of grades with the service quality alarm level according to time-delay or jitter parameter.
Above-mentioned alarm mode is directly for the parameter of total service quality threshold value to be set, the present invention also can utilize the existing comprehensive Qos value of determining the definite reflection of method synthesis service quality according to parameters such as the packet loss in total QoS parameter of being monitored, time-delay, shakes in real time, can adopt the method for the P.861 disclosed comprehensive Qos of determining of ITU-T herein, the threshold value of default Qos in MGW, in real time the Qos value determined is compared with corresponding Qos threshold value, when the Qos value arrives its corresponding threshold value, then trigger the reporting service quality report; Similar with above-mentioned packet loss, also can set the Qos threshold value of a plurality of grades herein, when the Qos value of monitoring arrives in the scope of some threshold values, then trigger the service quality report that reports corresponding grade, wherein carry the alarm class information of correspondence.
Step 203, MGC control the flow of the Packet Service that this MGW carried according to the service quality situation that monitoring result reflected that MGW reports.
The mode that this step is controlled flow can have following several concrete mode:
First kind of flow control mode: if comprise effective bandwidth in the monitoring result that MGW reports, then calculate and determine the current effective port number that carries according to this effective bandwidth, computational methods are: utilize the encoded bandwidth of current effective bandwidth divided by current operation, the value that obtains is effective port number, and described operation code bandwidth can set in advance in MGC; For example: the effective bandwidth that reports in the MGW service quality report is 27600kpbs, and current operation is speech business, adopt coding G.729 (speech data that comprises 20ms in packet), encoded bandwidth G.729 is 27.6kbps, and then effectively port number is 27600/27.6=1000.After determining effective port number, MGC judges that whether current service channel sum (this service channel sum has record in MGC) is greater than described effective port number, if, the service channel of restricted part Packet Service then, make current total service channel number be equal to or less than effective port number, thereby controlled service traffics; Otherwise, the service channel number is not controlled.The mode of described restriction is: the foundation of refusal new business passage; Or preestablish the priority of each service channel in the MGC kind, when the service quality variation, close the lower service channel of priority.
Second kind of flow control mode: the corresponding relation of default alarm grade and service channel restriction proportion in MGC, the restriction proportion of this service channel are the ratio that the service channel number that limited accounts for total service channel number, for example:
Alarm the not access of limit service passage for 0 grade;
1 grade of alarm restriction accounts for the service channel access of service channel sum 5%;
2 grades of alarm restrictions account for the service channel access of service channel sum 20%;
3 grades of alarm restrictions account for the service channel access of service channel sum 40%;
4 grades of alarm restrictions account for the service channel access of service channel sum 70%;
5 grades of alarm restrictions account for the service channel access of service channel sum 90%.
If comprise the alarm class information in the service quality report that MGW reports, then MGC inquires about the corresponding relation of described alarm grade and service channel restriction proportion, determine the alarm grade corresponding service aisle limit ratio that reports, limit with the service channel of this ratio, to improve the service quality of MGW current access.
The third flow control mode: the threshold value of default total QoS parameter of being monitored in MGC, method to set up herein is with above-mentioned at MGW the threshold value of total QoS parameter to be set identical; After MGC receives total QoS parameter that MGW reports, the threshold value that this total QoS parameter is corresponding with this parameter compares, when the parameter of the service quality of being monitored arrives its corresponding threshold value, then judge current service quality variation, limit according to the service channel of default service channel restriction proportion to current access.
Identical with above-mentioned MGW, threshold value herein can be one, also can be a plurality of graduate threshold values, when total QoS parameter that MGC received arrives in the scope of some threshold values, then with the grade of this threshold value grade as the current service quality; Under the situation that a plurality of service quality rating threshold values are set, also need in MGC, to set in advance the corresponding relation of service quality rating and service channel restriction proportion, after determining the current service credit rating, inquire about this corresponding relation, determine current service credit rating corresponding service aisle limit ratio, limit with the service channel of this ratio to current access.
Perhaps, MGC determines the Qos value of reflection service quality according to parametric synthesis such as the packet loss in the total QoS parameter in the service quality report, time-delay, shakes, and in MGC the threshold value of default one or more Qos, in real time the Qos value determined is compared with corresponding Qos threshold value, when the Qos value arrives its corresponding threshold value, then limit according to the service channel of default service channel restriction proportion to current access; That the Qos threshold value is set in MGW is similar with above-mentioned, also can set the Qos threshold value of a plurality of grades herein, when determining that the Qos value arrives in the scope of some threshold values, then with the grade of this threshold value grade as the current service quality, and the service quality rating that in MGC, sets in advance of inquiry and the corresponding relation of service channel restriction proportion, determine current service credit rating corresponding service aisle limit ratio, limit with the service channel of this ratio to current access.
The 4th kind of flow control mode: judge according to the monitoring result in the service quality report whether the service quality situation descends, if descend then reduce the required bandwidth of service channel.
Identical with the third flow control mode, can in MGC, preset the threshold value of total QoS parameter of being monitored, after MGC receives total QoS parameter that MGW reports, the threshold value that this total QoS parameter is corresponding with this parameter compares, when the parameter of the service quality of being monitored arrives its corresponding threshold value, judge that then current service quality situation descends.Perhaps, determine the Qos value of reflection service quality according to parametric synthesis such as the packet loss in the total QoS parameter in the service quality report, time-delay, shakes, and in MGC the threshold value of a default Qos, whether descend with the current service quality situation of Qos value judgement.
Herein, the mode that reduces the required bandwidth of service channel is: adopt the coded system littler than original coded system occupied bandwidth that the business in the service channel is encoded.For example suppose in speech business, speech business passage originally uses G.711 coding, when the service quality variation, use G.729, the less speech coding of other occupied bandwidth such as AMR encodes, can reduce the required bandwidth of service channel effectively, improve the service quality of Packet Service that MGW carries.Perhaps, reduce the required bandwidth of service channel, for example: can adopt the code check of 4.75kbps～12.2kbps when adopting the AMR coding, comprise various code rate such as 4.75,6.7,7.4,12.2 by the code check that reduces coding.Perhaps, also can reduce the required bandwidth of service channel, for example adopt the phonetic unit of different durations such as 10ms, 20ms, 30ms to pack by increasing grouping dimension, along with grouping dimension in the packet is long more, cause wrapping quantity and reduce, so the minimizing of packet header quantity, make occupied bandwidth reduce.
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 the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
