摘要： A method and a system to assist wireless telecom service providers to make strategic investment decisions in their wireless networks is provided. Geographical profitability information in a wireless network is determined to decide where to invest capital funds in order to increase the revenue and profit for wireless service providers. The profitability of a geographical area or a sector is calculated based on network Operation Measurements and subscriber CDR (Call Detail Record) data. The system prioritizes the geographical areas and sectors for capital investments based on the profitability of the areas and sites. Similar information may be determined to assist wireless service providers in developing a decommissioning strategy. Embodiments of the present invention may also be used to reduce network churn by understanding where dissatisfied subscribers experience poor service and where network investments need to be made to improve the services and reduce churn.

摘要： Systems and methods to assist wireless telecom service providers to determine the optimal core network evolution plan in a network planning time period. Total cost of ownership of wireless core networks is generally modeled to include capital expenditure, customer acquisition and retention cost, network operational cost and staffing and engineering cost. The total cost of ownership model is used to determine the optimal core network evolution plan at different layers of the core networks, which are modeled as a number of abstract networks in mathematical terms. A core network evolution optimization algorithm determines the optimal number of core network configurations and when to deploy the configurations in the planning period in order to minimize the total cost of ownership. A multi-level serving area optimization algorithm determines an optimal core network configuration at a given point of time.
