Abstract: When the operator of a mobile communication system applies one of: “dynamic Tracking Area List” or “smart paging” for more efficient paging, the “real” size of the Tracking Area, i. e., the number of cells over which a S1AP-paging is broadcasted on average, becomes difficult to calculate in real time; A method of determining tracking area size information is therefore proposed comprising: obtaining the average number of paging records per cell, and dividing it by average number of RRC-Connection-Setup, for terminated calls, per cell; the result is proportional to the real TA size; the obtained value is proposed as a new KPI, Key Performance Indicator.
