As shown in fig. 3, the present embodiment provides a method for obtaining voice call quality, which may include:
and S10, acquiring EPS fallback voice recording data of the target area.
The target area is an area in which the voice call quality needs to be calculated, and the target area may be a village, a town, a village, a city, a province, or the like. The voice recording data includes all user voice call data in the target area.
The EPS fallback voice recording data may be recording data (xDR) of voice service. Where x represents a variable, x is a generic name for the types of records preceding DR, and xDR represents some DR.
For example, the xDR may include Call Detail Record (CDR) data, transaction Detail Record (TDR) data of a voice call service; IP derived record (IPDR) of transmission control protocol/internet protocol (TCP/IP) communication, and the content of the xDR is not particularly limited in this embodiment.

And S20, determining the value of the evaluation parameter of the target crowd in the target area according to the voice recording data.
Wherein the target population may include one or more of: a local user of a target area, a user who roams to the target area domestically, and a user who roams to the target area internationally.
In an alternative embodiment, the target group may be determined based on an MSISDN (mobile subscriber integrated services digital network number) field of the mobile subscriber in the EPS fallback voice record data and a segment affiliation table of the local city number of the operator.
For example, the target population zone may be determined from the MSISDN field as: a local subscriber in the target area, a subscriber who roams domestically to the target area, and a subscriber who roams internationally to the target area.
Specifically, MSISDN = CC + NDC + SN, for example, MSISDN 86 130H0H1H2H3ABCD.
Wherein, CC: indicating a country code, such as 86 for china.
NDC: access numbers indicating network operators are assigned to the respective network operators by communication authorities of respective countries. For example, the access numbers of the china mobile network are 134-139, 150-152, 188, etc., the access numbers of the china unicom network are 130-132, 185-186, etc., and the access numbers of the china telecommunication network are 133, 153, 180, 189.
SN: the last 8 digits, representing the customer number, i.e. the mobile phone number, are assigned by the network operator. Wherein, the 4 bits of HOH1H2H3 represent the home city of the user.
In this embodiment, first, a user who roams internationally to a target area is screened from users in the target area, that is, CC in MSISDN field of the user is analyzed, and a user who is not 86 in CC is screened, that is, a user who roams internationally to the target area. And then screening out local users of the target area from the screened users of the target area, namely, comparing four bits of HOH1H2H3 in the MSISDN field with an affiliation number segment table of the city of the operator, screening out users matched with the number segment of the target area, namely, the local users of the target area, and finally determining the users left after two screening as the users roaming to the target area in China.
Specifically, the evaluation parameter may include one or more of the following: call completing rate, access delay, voice interruption times, voice single-pass times and call drop rate.
It should be noted that the content of the evaluation parameter may be configured according to an actual demand (for example, a demand for evaluating voice call quality).
The call completing rate may be a ratio of the number of times of successful establishment of the caller to the number of times of the request for establishing the caller in the evaluation period. The duration of the evaluation period may be configured according to actual requirements, which is not limited in the embodiment of the present application.
The access delay may be a ratio of a total call setup delay to a number of call setup successes within an evaluation period.
The number of times of voice interruption may be the number of times of voice calls in which a preset number of packet losses or a packet interval delay exceeds a first duration are continuously lost after the voice call starts within the evaluation period. The preset number and the value of the first duration may be configured according to actual requirements, which is not limited in the embodiment of the present application.
Illustratively, the preset number may be 20, 25 or 30, etc., the first duration may be 90ms, 100ms or 110ms,
the number of voice single pass times may be the number of events in the evaluation period when the last call time of the user is within the second time period and the two parties establish a call again within the third time period. The values of the second duration and the third duration may be configured according to actual requirements, which is not limited in this embodiment of the present application.
For example, the second time period may be 10, 20s, 30s, etc., and the third time period may be 10, 25s, 40s, etc.
The call drop rate may be a ratio of the sum of the number of call drops of the calling party and the number of call drops of the called party to the sum of the number of answer times of the calling party and the number of answer times of the called party in the evaluation period. That is, the call drop rate may be the probability that the user is abnormally interrupted in the EPS fallback session.
It should be noted that the unit of the number of speech pauses and the number of speech pauses may be times/day/person. That is, after the number of speech pauses and the number of speech pauses within the evaluation period are calculated, the number of speech pauses and the number of speech pauses can be divided by the number of days of the period and the number of users to obtain the number of speech pauses/day/person and the number of speech pauses/day/person. The call completing rate, the access delay and the call drop rate of the voice call can be percentage values.
It should be noted that, the content and definition of the evaluation parameter may be configured according to actual requirements, and this is only an example and is not specifically limited in the embodiment of the present application.
In this embodiment, in order to evaluate the voice call quality in the target area in terms of accessibility, maintainability, integrity and the like of the voice call, configuring the evaluation parameters includes: call completing rate, access delay, voice discontinuous times, voice single-pass times and call drop rate. The call completing rate and the access time delay are used for evaluating the accessibility of the voice call; the voice interruption times and the voice single-pass times are used for evaluating the retentivity of the voice call; the dropped call rate is used to assess the integrity of the voice call.
In one embodiment provided by the present invention, the target population is divided into: after a local user in the target area, a user who roams to the target area domestically, and a user who roams to the target area internationally, the value of the evaluation parameter of each target crowd in the target area can be determined, and the values of the evaluation parameters corresponding to the local user in the target area, the user who roams to the target area domestically, and the user who roams to the target area internationally can also be determined respectively.
Illustratively, the values (call-on rate, access delay, number of speech interruptions, number of speech single-passes, and call drop rate) of the evaluation parameters for a target group are determined as follows:
determining the call completing rate of the target population: the number of successful caller setup times of the target group may be the number of times that the caller side receives a Session Initiation Protocol (SIP) 180 (called ring) response message, the number of times that the caller setup request of the target group may be the number of times that the PSBC receives an initial Invite message sent by the 5G user, and it is determined that the call completing rate of the target group may be a ratio of the number of times that the caller side receives the SIP180 response message to the number of times that the PSBC receives the initial Invite message sent by the 5G user within an evaluation period.
Determining the access time delay of the target crowd: the total call setup delay of the target group is a time difference between the receiving of the SIP180 message by the calling side and the sending of the SIP Invite message by the calling side, and it is determined that the access delay of the target group may be a ratio of the time difference between the receiving of the SIP180 message by the calling side and the sending of the SIP Invite message by the calling side to the number of times of receiving the SIP180 response message by the calling side in an evaluation period.
Determining the voice interruption times of the target population: and counting the number of voice calls of which the packet loss is preset continuously or the packet interval delay exceeds a first time length after the voice calls of the target group start in the evaluation period, and taking the number of voice interruptions of the target group.
Determining the voice single-pass times of the target population: and assuming that the second time length is 30s and the third time length is 30s, determining the event that the first call time length is within 30s and the two parties establish calls again within 30s as the voice single-pass, and counting to obtain the voice single-pass times of the target population in the evaluation period.
Determining the call drop rate of the target population: the number of dropped calls of the calling party may be the number of times that a Session Border Controller (SBC) of the calling party, when the bearer of the calling party is abnormally released, sends an SIP BYE message with a cause value 503 (due to overload or maintenance, a server or gateway cannot process a request) as a first disconnecting network element (giving both directions to the calling party and the called party); the called call drop times may be times when the bearer on the called side is abnormally released, and the called SBC serves as a first disconnect network element (giving both the calling and called directions simultaneously) to send an SIP BYE message with a cause value 503. The number of caller responses may be the number of times the caller side received the SIP 200 (successful response) message. The called response times may be the times that the called side sends out the SIP 200 message. Determining the call drop rate of the target crowd as follows: the method comprises the steps that when the calling side bearing is abnormally released, the calling SBC serves as a first disconnecting network element to send the SIP BYE message with the reason value 503 times, the sum of the times that the called SBC serves as the first disconnecting network element to send the SIP BYE message with the reason value 503 times when the called side bearing is abnormally released is compared with the ratio of the sum of the times that the calling side receives the SIP 200 message and the times that the called side sends the SIP 200 message.
And S30, determining the voice call quality of the target area according to the value of the evaluation parameter of the target crowd and the preset strategy of the target crowd.
The preset strategy is used for describing the relation between the values of different evaluation parameters and the voice call quality of the target crowd. Different target groups may correspond to different or the same preset strategies.
Optionally, the preset policy may include, but is not limited to, the following two cases:
in case 1, the preset policy may include different conditions, and the evaluation parameter values satisfy scores corresponding to the different conditions.
For example, determining the voice call quality of a target group of people may include: the condition that the value of each evaluation parameter of the target population meets in the preset strategy can be determined, the score corresponding to the condition that the value meets is obtained and used as the score of each evaluation parameter, and then the average value or the maximum value or the sum or the other value of the scores of each evaluation parameter of the target population is calculated and used as the voice call quality of the target population.
Illustratively, table 1 illustrates the contents of one preset policy.
TABLE 1
In case 2, the preset policy may include different conditions, scores corresponding to evaluation parameter values satisfying different conditions, and weights of the evaluation parameters.
For example, determining the voice call quality of a target group may include: the method comprises the steps of firstly determining the conditions which are met by the value of each evaluation parameter of the target group in a preset strategy, obtaining the value corresponding to the condition which is met by the value of each evaluation parameter as the value of each evaluation parameter, then obtaining the weight of each evaluation parameter in the preset strategy, and finally calculating the weighted sum of the values of each evaluation parameter of the target group as the voice call quality of the target group.
Illustratively, table 2 illustrates the contents of another preset policy.
TABLE 2
It should be noted that tables 1 and 2 are only by way of example, and illustrate the form and content of the preset policy, and do not constitute a specific limitation. In practical application, the content and form of the preset strategy can be configured according to actual requirements.
Specifically, S30 can be realized by the following steps 1 and 2.
Step 1, obtaining the voice call quality of a target group.
In one possible implementation, corresponding to the foregoing case 1, the voice call quality Q of a target group satisfies the expression: q = f (X) i ). Wherein I is greater than or equal to 1 and less than or equal to the total number I of the evaluation parameters of the target population. X i And the score corresponding to the condition met by the ith evaluation parameter of the target population in the preset strategy. f (& gt.) is to perform first calculation on scores corresponding to conditions met by all evaluation parameters of the target population in a preset strategy, and the first calculation can be averaging, maximum value calculation or other calculation.
For example, assuming that the preset policy of a target group may be table 1, the connection rate, the access delay, the number of voice interruptions, the number of voice single-pass times, and the call drop rate may be converted into corresponding scores through table 1. If the obtained connection rate of the target group is 98%, the access delay is 3s, the number of voice break times is 2/day/person, the number of voice single pass times is 1/day/person, and the call drop rate is 0.6, as can be seen from the contents in table 1 below, the value of the connection rate of the target group is 100, the value of the access delay of the target group is 100, the value of the voice break times of the target group is 60, the value of the voice single pass times of the target group is 80, and the value of the call drop rate of the target group is 80, the above-mentioned values are averaged to obtain the voice call quality of the target group as 84.
In another possible implementation manner, corresponding to the foregoing case 2, the voice call quality Q of a target group satisfies the expression:
i is greater than or equal to 1 and less than or equal to the total number of evaluation parameters I, X of the target population i Is the score corresponding to the condition met by the ith evaluation parameter of the target population in the preset strategy, A i The weight of the ith evaluation parameter of the target population.
For example, the preset policy of a target group may be table 2, and the connection rate, the access delay, the number of voice interruptions, the number of voice single-pass times, and the call drop rate are converted into corresponding scores through table 2. If the obtained connection rate of a certain target group is 98%, the access delay is 3s, the number of voice break is 2/day/person, the number of voice single pass is 1/day/person, and the call drop rate is 0.6, it can be seen from the contents in the following table 2 that the value of the connection rate of the target group is 100, the weight is 25%, the value of the access delay is 100, the weight is 25%, the value of the voice break is 60, the weight is 15%, the value of the voice single pass is 80, the weight is 15%, the value of the call drop rate is 80, and the weight is 20%. The voice call quality of the target population is 87 by calculating a weighted sum of the scores of each evaluation parameter of 100 × 25% +60 × 15% +80 × 20% = 87. For example, the evaluation parameters are: and the total number of evaluation parameters of the call completing rate, the access delay, the voice interruption times, the voice single-pass times and the call drop rate is I =5.
For example, the target population may be a local user in the target area, a user who domestically roams to the target area, and a user who internationally roams to the target area, and in step 1, the voice call quality of the local user in the target area, the voice call quality of the user who domestically roams to the target area, and the voice call quality of the user who internationally roams to the target area may be respectively determined according to a preset policy of the local user in the target area, a preset policy of the user who domestically roams to the target area, and a preset policy of the user who internationally roams to the target area.
In this embodiment, the voice call quality corresponding to the local user in the target area, the user roaming to the target area domestically, and the user roaming to the target area internationally is calculated, so that the voice call quality of different users can be evaluated more specifically.
For example, the predetermined policy for the local user in the target area may be as shown in table 3, where the voice call quality of the local user in the target area = 25% score of call completing rate + 25% score of access delay + 15% score of number of voice interruptions + 15% score of number of voice single-pass + 20% score of call dropping rate.
TABLE 3
For example, the predetermined policy for a user who roams home to a target area may be as shown in table 4, where the voice call quality of the user who roams home to the target area = score 25% for call completing rate + score 20% for access delay + score 15% for number of voice interruptions + score 15% for number of voice single-pass + score 25% for dropped call rate.
TABLE 4
For example, the predetermined policy for the user who roams internationally to the target area may be as shown in table 5, where the voice call quality of the user who roams internationally to the target area = score of call completing rate 20% + score of access delay 20% + score of number of voice interruptions 15% + score of number of voice single-pass + score of call dropping rate 30%.
TABLE 5
And 2, taking the weighted sum of the voice call quality of the target crowd as the voice call quality of the target area.
In a possible implementation manner, when there is only one target group, the weighted sum of the voice call quality of the target group is the voice call quality of the target group.
In another possible implementation manner, when there are multiple target people groups, the preset weight of each target people group may be configured according to actual requirements. The sum of the preset weights for all target populations is 1. For target people with high attention, a higher preset weight can be configured.
For example, when the target population includes a local user in the target area, a user who domestically roams to the target area, and a user who internationally roams to the target area, the local user in the target area corresponds to the first weight value, the user who domestically roams to the target area corresponds to the second weight value, and the user who internationally roams to the target area corresponds to the third weight value, the three weight values are added to be 1, and the numerical value of the weight values can be set according to the actual situation. Assume that the first weight value is 50%, the second weight value is 30%, the third weight value is 20%, and the voice call quality of the EPS fallback target area = 50% of the voice call quality of the local user in the target area + 30% of the voice call quality of the user who has roamed domestically to the target area + 20% of the voice call quality of the user who has roamed internationally to the target area.
In one possible implementation, the voice call quality of the target area may be represented in the form of a score.
In another possible implementation manner, the voice call quality of the target area may be represented by a score corresponding to the grade.
For example, as shown in table 6, different voice call quality score ranges may correspond to different rating levels. For example, with reference to table 6, if the score of the voice call quality of a target area is 95, the evaluation level of the voice call quality of the target area is excellent; if the score of the voice call quality of a target area is found to be 85, the evaluation grade of the voice call quality of the target area is good; if the score of the voice call quality in one target area is found to be 65, the evaluation level of the voice call quality in the target area is poor.
TABLE 6
| Between scoring areas | Score value>90 minutes | Score of 70 or less<90 minutes | Score value<70 points out |
| Rating of evaluation | Superior food | Good wine | Difference between |
It should be noted that table 6 illustrates the relationship between the score and the rank by way of example only, and is not particularly limited.
