Mobile Analyzing, Planning and Optimizing Heterogeneous Mobile Access and Core Networks
The Features NetWorks Mobile is a tool for analyzing, planning and optimizing the fixed-line part of your (mobile) radio network based on GSM, GPRS, UMTS, HSPA, WiMAX or LTE. GSM CS IP The benefits of using NetWorks Mobile are the reduction of investment and operational costs, the possibility to provide efficient and reliable end-to-end services, and the acceleration of decision processes by automated planning work. GPRS UMTS SS7 SIP MPLS ATM Centralized planning departments are provided a tailored planning tool for designing multi-service core networks under consideration of essential aspects of the transport network. HSPA Eth SDH Decentralized planning departments are supported with a tool for designing mobile access networks (BSS/UTRAN). Different planning scenarios can be conveniently created and easily compared. The graphic and tabular functions and the interactive user interfaces enable you to plan your networks creatively and efficiently and to show the results clearly. LTE WiMAX WDM For general features please refer to our information flyer NetWorks Products. The planner of heterogeneous mobile networks is supported by a comprehensive planning tool, which gives the opportunity to maintain vertical transparency through all network layers. 2G Network (GSM/GPRS) 4G Network (LTE) 3G Network (UMTS/HSPA) Mobile Service Delivery Platform Traffic estimation Erlang Traffic (Voice, Video,...)

Analyzing, Planning and Optimizing Heterogeneous Mobile Access and Core Networks Service-oriented Dimensioning of Heterogeneous Mobile Access Networks How to optimize structure and dimensioning of fixed-line mobile access networks What is the current traffic load on the interfaces/links of the mobile access network? How shall the capacity on the interfaces/ links be developed for GERAN/UTRAN? Which modifications have to be made with regard to dual homing of base stations in eutran? How should traffic between enodeb and to central network elements be distributed? How should the logical network topology on the transport network be mapped? Estimate the traffic at the base stations, if possible, from traffic measurements. Use specific calculation rules for dimensioning interfaces (Abis, A, Gb; Iub, Iur, IuCS, IuPS, ). Migrate existing hierarchical access networks with base stations and controllers to new topologies. Use eutran-specific calculation rules for the capacity of interfaces (X2, S1). Dimension Ethernet, SDH and ATM transport networks. The decentralization of network intelligence in 4G mobile networks results in logical access structures with direct connections between base stations.
Traffic-based Structure and Capacity Planning for Mobile Backhaul Networks How to develop resources of mobile backhaul networks with growing traffic and quality demands How can the BTS be connected to BSC, and the BSC to MSC/SGSN by transport systems? How can the NodeB be connected to RNC, and the RNC to MSC/SGSN by transport systems? How can the enodeb be connected to S-GW by transport systems? Which economical effect does the implementation of 2G/3G/4G backhaul have on common transport systems? Determine the most efficient access/aggregation network structure for 2G/3G/4G. Select the best alternatives from wireless and wireline backhaul taking geographical constraints into account. Determine the required transmission capacity of TDM or Ethernet systems in accordance with the traffic load. Calculate the costs of the backhaul solution. Based on altitude maps it is possible to define efficient microwave links, in order to connect them to sites with available access to the fiber-optic infrastructure.
Analyzing, Planning and Optimizing Heterogeneous Mobile Access and Core Networks Multi-Service Traffic Analysis and Forecast How to determine required investments for continuously growing traffic or for materializing marketing forecasts Where are capacity bottlenecks and are there spatial correlations? Which traffic is handled in total at base stations of one region? Which traffic can be expected next month, in six months or in one year? Which amount of traffic flows from one core node to another one? What investment is necessary to cover the predicted traffic? Which specific capacity extensions should be implemented? Visualize node and link related measurements. Aggregate measurements for areas defined by polygons or administrative rules. Predict future traffic per node assuming the same growth rate as in the past. Use currently measured traffic on trunk groups for predicting the future traffic matrix. Define required capacities for future traffic and calculate the upgrade cost. Generate graphical and tabular reports on selected network elements, e.g. for nodes exceeding a given load threshold. Evaluation of traffic measurements and forecast in geographical context Graphical Report on Affected Cells Measurement Analysis Lists of Cells and Sites for Extension Investment necessary to handle predicted traffic Traffic Forecast (per Cell) 16,0 15,5 13,5 13,0 Q2/10 Q3/10 Q4/10 Q1/11
Mobile Core Network Planning Including Transport Layers How to develop the capacities of mobile core networks with regard to the quality of service requirements Which type and which capacity of switching centers/media gateways/session border controllers are required at which locations? Which type and which capacity of servers (IN, VAS, IMS) are required at which locations? Which TDM traffic is generated between the core components? Which IP traffic is generated between the core components? What is the optimal way of interconnecting with legacy and other networks? Calculate the required throughputs and number of ports for media gateways/session border controllers. Calculate the required processing capacities and number of ports for server hardware. Dimension the trunks in circuit-switched networks under consideration of overflow or load sharing. Dimension the packet-switched links under consideration of individual protocol overheads of carried services. Dimension the interconnection links with the objective of cost reduction.

Analyzing, Planning and Optimizing Heterogeneous Mobile Access and Core Networks Traffic-Related Cost Allocation How to determine production costs per traffic unit for different services implemented on a heterogeneous mobile network What are the production costs per Erlang/ per Mbit/s for each individual service? Can production costs be reduced with growing traffic in the network? How can the costs be shared fairly between high- and low-priority services? What is the influence of additional capacities for recovery mechanisms on service production costs? Calculate costs per load unit on individual nodes and links, differentiated by service classes. Analyze average costs per traffic unit (Erl, Mbit/s) for distance classes or per site with growing traffic. Use class-based dimensioning and cost allocation algorithms. Evaluate redundancy concepts in different layers and check their influence on service production cost.
