Voice calls users' behavior in terms of call duration

During base station subsystem (BSS) or radio access network (RAN) construction, the system capacity is planned according to the expected traffic volume in the coverage areas. When the traffic volume is within the planned capacity, the system can provide services properly. However, in certain situations, such as major events or in dense destinations, the traffic volume sometimes exceeds the planned capacity, leading to base stations overload. At times, it can happen due to unpredictable user’s behavior. If no measures are taken to protect the network, system performance may deteriorate noticeably. To avoid this, daily network performance KPI’s (Key Performance Indicator) observation is performed, but it is not enough, user’s habits are very important too. Especially when it comes to voice calls service, which is extremely important and widely used. Voice calls are one of the key services in today mobile business and require high quality of service. The focus of this research is on user habits of using voice call services in different locations. Main attention is paid to voice call duration measurement of various user groups. These user groups are composed from regular mobile network users who makes voice calls at six typical locations. The analysis includes voice calls duration distributions according to used technology for carrying a call, service payment type and other significant statistics. Collected data might be an important input for service providers or other parties, which are interested in humans communication habits. Comprehensible behavior of voice call users can help in selecting appropriate flow control mechanisms and ensure smooth call control management of circuit switched (CS) services.
