Hereinafter will and combine embodiment to specify the present invention with reference to accompanying drawing.Need to prove that under the situation of not conflicting, embodiment and the characteristic among the embodiment among the application can make up each other.
Fig. 1 is the flow chart according to the Voice Quality Monitor method of the embodiment of the invention.As shown in Figure 1, this sound quality method for supervising mainly comprises following processing:
Step S102: in communication process, obtain the speech data of current talking;
Step S104: the speech data to obtaining carries out analyzing and processing, confirms the current IP network condition.
In the correlation technique, after customer complaint, just know the voice quality existing problems, and, need carry out artificial packet capturing analysis at the scene in order to solve voice quality problem, obviously there is drawback in this method, loses time and manpower.In method shown in Figure 1, in communication process, obtain the speech data of current talking in real time; Speech data to obtaining carries out analyzing and processing, confirms the current IP network condition.Solved in the correlation technique to solving voice quality problem, adopted the on-the-spot scheme that artificial packet capturing is analyzed of carrying out, lost time and problem such as manpower, and then can in time solve voice quality problem, effectively saved time and manpower.
Preferably, step S104 may further include following processing:
(1) confirms the voice quality value of information of current talking according to the speech data that obtains;
Wherein, the above-mentioned voice quality value of information may further include but be not limited to following one of at least: time delay value, jitter value, packet loss.
(2) the voice quality value of information and first threshold value are compared, confirm the current IP network condition.
In preferred implementation process, before obtaining the speech data of current talking, can obtain above-mentioned first threshold value through following a kind of at least mode:
First kind: the response user instruction is provided with first threshold value on Media Gateway Controller; Receive afterwards and come from above-mentioned first threshold value that Media Gateway Controller issues;
Second kind: response user instruction, above-mentioned first threshold value of dynamic-configuration on WMG.
Wherein, above-mentioned first threshold value can be for judging whether to occur the threshold value that network congestion is set; In preferred implementation process, above mentioned the voice quality value of information and first threshold value are compared, confirm that the current IP network condition may further include following processing:
(1) when the voice quality value of information surpasses first threshold value, confirms that congestion condition appears in the current IP network;
(2) otherwise, confirm that the current IP network condition is normal.
In preferred implementation process, except first threshold value is set, the one or more threshold values except that first threshold value can also be set, wherein, one or more threshold values are all greater than first threshold value;
When the voice quality value of information surpasses first threshold value, can judge whether the voice quality value of information surpasses the one or more threshold values except that first threshold value; If, confirm that congested grade appears in the current IP network then according to the comparative result of the voice quality value of information and one or more threshold values.
Through above-mentioned processing, can be according to network congestion degree with a plurality of grades of congested difference, for example, Three Estate: serious, general and slight.In actual maintenance process, can do corresponding processing according to various ranks.
In preferred implementation process, before obtaining the speech data of current talking, can obtain above-mentioned one or more threshold value through following a kind of at least mode:
First kind: the response user instruction is provided with above-mentioned one or more threshold value on Media Gateway Controller; Receive afterwards and come from above-mentioned one or more threshold values that Media Gateway Controller issues;
Second kind: response user instruction, the above-mentioned one or more threshold values of dynamic-configuration on WMG.
In practical application, can also adopt above-mentioned dual mode to obtain the report cycle parameter, promptly can receive and come from the report cycle that Media Gateway Controller issues; Also can respond user instruction, the above-mentioned report cycle of dynamic-configuration on WMG.
It should be noted that after the Media Gateway Controller reporting information, in report cycle, no longer report usually to have only and wait until that report cycle later just can be once more with the information reporting that surpasses threshold value.
Preferably, after execution in step S104, can also comprise following processing one of at least:
(1) reports the current IP network condition according to report cycle to Media Gateway Controller (being soft switch (Soft Switch abbreviates SS as));
(2) congestion condition that the current IP network is occurred is alarmed;
In the practical implementation process, can provide corresponding alarm, with the problem of reminding the timely processing of staff to occur according to congestion level.Consistent with congestion level, alarm also is divided into Three Estate: serious, general and slight.
(3) the order bag and the medium bag that grasp current talking are also preserved;
In the practical implementation process, can the order bag and the medium bag that grasp be kept in the background server.
(4) record surpasses the voice quality value of information of first threshold value.
In the practical implementation process, can write down data such as time delay value, jitter value or packet loss with the mode of daily record above threshold value.These data can be used as Backup Data, make things convenient for the staff to check at any time, and the while also analyzes for the staff and handling problem provides foundation.In addition, if SS or MG no longer issue threshold value afterwards, these data also can be used as new threshold value and use.
