The main attention when planning the network of a mobile operator is paid to frequency distribution and electromagnetic compatibility. The main argument is that the solution of this problem will ensure the fulfillment of the conditions of optimal frequency resource allocation and, as a consequence, will allow to optimize the level of interference in neighboring zones. At the same time, the issue of uniformity of traffic distribution among network elements is not considered. As a result, this approach negatively affects the performance and quality of service. In order to increase the efficiency of load distribution in the planning of base station service areas, it is proposed to additionally take into account the results of the analysis of service event flows in cells and the data of the billing system. Initially, radio planning determines the further quality of services on mobile network. At the same time there is no adaptation to changing external conditions. In large cities with a developed infrastructure, the constantly changing situation forces mobile operator to constantly adjust the condi-tions of signal propagation. The constant increase in volume of transmitted information requires the optimization of load distribution on cellular structure, the search for optimal methods of ensuring electromagnetic compatibility (EMC), the territorial distribution of the frequency resource of the operator. High efficiency of network quality in such conditions is provided by the operator at close interaction of the services of planning, optimization and operation of network by use of expensive soft-ware. This paper offers a look at the problem in terms of subscriber traffic. In the paper, the strategy of access without redundancy is considered, when in the sector radio channels are designed to service both calls within the cell and hand-made calls, without radio redundancy channels to service handover. Therefore, the probabilities of denial of service for incoming calls and handovers are equal.References
