Do you know the meaning of call concurrency in okcc?

  In the field of voice communication , Call concurrency is a common but unfriendly term , It is often difficult to understand , I don't know what the effect is .
        Call concurrency , Popular speaking , It refers to the number of simultaneous calls on the system .
        that , What is the difference with the number of users on the communication system ？
        Number of users , Very easy to understand , It can indicate the size of users carried by the system . Many people think that the number of concurrent users is the number of users , It's not true .
        for instance , A communication system has 100 Users , The number of users is 100 individual . however , this 100 Users are not always on the phone , Usually , Most of the time, only a few people are making calls , Then the number of calls on the system is the number of concurrent calls . Obviously easy to see , Usually , Call concurrency is less than the number of users .
        that , Is there a time when the call concurrency is greater than the number of users ？
        yes , we have .
        Take the field of call center as an example , team （ A group of employees ） Make outbound calls , To improve the seating （ Team staff ） Work efficiency , Predictive outbound call service can be used , First call a group of called users , The number of calls exceeds the number of team seats , Assign the call to the team seat after the called person answers . Because the proportion of being called will not reach 100%（ Usually not more than 50%）, Compared with the traditional call method, it can greatly save the time of waiting for the called to answer , Therefore, it can greatly improve work efficiency . here , Call concurrency is greater than the number of users .

        Call concurrency is also one of the important indicators to measure the performance of voice communication system . Call concurrency is large , It often means that the system has strong carrying capacity , Better performance . The same 10000 door switch , Support 1000 Concurrency and 10000 Concurrency is not the same , The development of its system & The construction cost will also be quite different .
        For operators , Concurrency is also a reference index to measure operational efficiency . Although the call concurrency of the communication system will not be constant , It changes all the time , And the difference of call connection rate will also greatly affect the operational efficiency , But in the case of general convergence of business types , Under the statistical law of large business volume , There will be an obvious linear correlation between operation efficiency and call concurrency .
       1 How much business can line concurrency generate in one day ？
        At the extreme , One day 24 Hours , An hour 60 minute , If you keep calling 24 Hours , Theoretically, the upper limit of business volume is 1440 minute . But most systems cannot keep calling 24 Hours , General business peak continues 6-10 Hours , Looks like it's just 1440 Minutes of 2 Success 4 become , Not more than 600 minute .
        actually , In communication operation , The billing unit of the call is minutes , But many calls cannot be reached 60 Seconds will follow 1 Charge per minute , Especially in marketing outbound calls , Many calls end in a few seconds , therefore , The number of minutes that actually produce benefits may theoretically far exceed 600 minute ; however , Because the call takes time from start to connect , And many calls will not be answered , These times will not produce operational benefits . therefore ,1 How much operational benefits can line concurrency produce , And business type 、 Call connection rate is closely related ; When the service type and call connection rate are relatively certain , The economic value that system concurrency can produce is relatively constant , therefore , System concurrency is also an important indicator to measure voice communication operation , Even more important than the number of users .
