Avoid resource misappropriation with TEMS Capacity Management

Simplifying Network Capacity Management in a Complex World

Managing a network is complicated; with the increased consumer and business reliance on smartphones, networks are experiencing constant and unprecedented growth in data volume. The resulting need to deliver a good customer experience across multiple services with different data QoS requirements introduces capacity management challenges for wireless operators.

TEMS Capacity Manager, Ascom’s mobile network capacity planning and management solution provides carriers with visibility into where and when potential capacity bottlenecks will occur, details on which resources will be constrained, and scenario analysis to assess potential remedies.  

Our solution uses switch and oss parameters from actual traffic to drive advanced analytics and simulations – creating an accurate representation of resource utilization for every carrier in every sector.  This simulation captures the complex non linearities that arise from both the traffic mix and the effects of soft capacity in the RAN environment to identify where resource constraints will result in customer experience falling below target QoS levels.  

Use TEMS Capacity Manager to perform sensitive What If analysis scenarios – witness the effect of added capacity on surrounding sites, identify areas for network remediation,  and efficiently prioritize where and when to expand the network.


Improve Capex and Opex Efficiency

Using TEMS Capacity Manager, customers have been able to identify better when expansion is needed and to defer RAN CAPEX expenditures and carefully manage capital in their networks’ expansion.  TEMS Capacity Manager can also be used to simplify the complex network expansion workflow, improving both CAPEX and OPEX efficiency.

Delivering Optmized Capacity Management

Optimize Your Capacity Management Based on the User Experience

TEMS Capacity Manager employs a variety of sophisticated analysis techniques to efficiently manage network resources. With TEMS Capacity Manager, the complete capacity state of the radio access network is reported, areas for remediation are immediately identified, and predictions on impending capacity limitations are provided. With the use of Headroom reports the user is able to get a snapshot of the radio access network and where potential dimensioning issues may be arise. By generating charts and reports that support solution identification and validation, TEMS Capacity Manager can help improve overall network engineering efficiency.

Create “What-If” Scenarios

TEMS Capacity Manager contains a customized model for each distinct network element. Whenever single value metric reports are re-calculated, these models are updated. With just a few clicks, evaluate the impact of network changes, experiment the effect of configuration changes, varying traffic loads, constraining resources, and other special events on a network, and determine how to best remediate a capacity problem.

Element Level Trending

Perform Element Level Trending through Forecasting

Perform element level trending with TEMS Capacity Manager’s top-down and bottom-down forecasting. This combination of forecasting can project traffic growth for every measured cell/sector/carrier and accurately estimate the date when capacity will be exhausted. Having an accurate idea of when capacity will be diminished can help better man

age capacity expansion project lead times. TEMS Capacity Manager’s ability to classify expansions based on element level trending leads to much more efficient CAPEX expenditures and improved OPEX due to TEMS Capacity Manager’s ability to provide radio network engineers a prioritized list of items needing attention. Because radio network engineers are able to stay informed at all times with TEMS Capacity Manager’s analytics, the time required to prepare expansion briefings is also drastically reduced.


The detailed capacity modelling performed by TEMS Capacity Manager takes into account user experience KPIs in addition to network element engineering KPIs. These KPIs provide analyses on different network resources and the effect they have on session quality. Planning expansions based on user experience KPIs also makes it easier to provide a consistent user experience across the entire network and across a wide range of network hardware configurations.

It is possible in WCDMA and LTE based systems to keep adding additional users without causing hard blocking at call admission. As additional users are added interference increases and the overall user experience decreases. This ability to cope with additional demand is known as soft capacity, and is one of the reasons that some WCDMA and LTE carriers are capable of supporting substantially more carried traffic (while maintaining a similar user experience) than 2G carriers. How the user experience decreases is a function of UE distribution with a sector, external interference, and other environmental parameters. This means that if typical cell capacity is used as a guideline for planning expansions across the entire network (rather than estimating soft capacity on a discreet carrier basis) then high capacity carriers will be expanded well before they should be, and low capacity carriers will not be noticed until they have significantly violated their KPIs.

The detailed traffic modelling performed by TEMS Capacity Manager specifically allows dimensioning to user experience KPIs in addition to network element engineering KPIs. These by necessity must consider the combined utilization of different network resources and the affect that this has on session quality.


TEMS Capacity Manager customers rely on the solution to efficiently expand their macro layer cellular network in a just in time manner. At some point their most critical resource, spectrum, will become exhausted and from then on there is no clever dimensioning technique that can resolve capacity issues, unless there is offload to a small cell or hetnet (micro) layer. Comparing element level trending with spectrum availability allows for a micro layer strategy to be evolved Justin in time, and ssists in devising spectrum re-farming strategies that can maintain high levels of user experience.


Today TEMS Capacity Manager already supports the required data feeds from all Ericsson, Huawei, and ZTE OSSes for 2G, 3G (WCDMA), and 4G (LTE) networks. Integration of another vendor’s OSS into the solution will take two months from project launch.
