Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the embodiment of the present invention provides a kind of Speech Assessment Methods, its executive agent is the network equipment, for example
Server.Methods described includes：
101st, obtain the CDR (Call Detail Records, call detail record) of each user in target area.
Wherein, the CDR includes：Message registration at least one times；The message registration includes：It is the call time started, logical
Words end time, rear subscriber number, called number.Additionally, the message registration also includes：When call drop mark is with connecting
Prolong.Wherein, call drop is identified for representing the situation in this call with the presence or absence of call drop.For example, when call drop is designated 1, say
There is the situation of call drop in bright this call；When call drop is designated 0, illustrate that this call does not have the situation of call drop.
102nd, from the CDR of unique user, it is determined that independent at least one times converse.
In real life, user is in communication process probably due to the reason such as call drop, needs to call again, so as to right
For a communication process, a plurality of message registration is there is in CDR.Analyze from network side, these message registrations represent
Different calls.But from for the angle of user, between these message registrations be not it is independent, and should be used as once complete
Whole call is treating.
Therefore, the process that implements of step 102 is：According to the CDR of unique user, when the call of a message registration is tied
The beam time is less than Preset Time, and the master of message registration twice with the time interval of the call time started of message registration next time
When being Subscriber Number and called number all same, it is determined that there is incidence relation in message registration twice；There will be incidence relation
N times message registration be defined as once independent call.
It is exemplary, CDR of the table 1 for certain user, the Subscriber Number is：188xxxxx359.
