- Page 2 TEMS ™ AUTOMATIC 8.1 GAIN CONTROL OF YOUR NETWORK’S QUALITY In many parts of the world, today’s wireless telecommunications industry is characterized by saturated markets, high churn, declining revenue, and lower-than- expected data usage. All operators are looking for ways to control costs, maximize their limited resources, maintain a high-quality offering in order to attract new customers, and keep existing customers satisfied. ...
- Page 3 TEMS ™ AUTOMATIC 8.1 HOW DOES AN OPERATOR KEEP CUSTOMERS SATISFIED? In the competitive Mobile Internet environment, delivered Quality of Service (QoS) is the key. In fact, good QoS can make the difference between a satisfied subscriber and a former subscriber. Operators must take control of network quality. To best manage this, the operator must receive con- tinuous feedback on the live network’s QoS, see the impact of optimization efforts on a regular basis, and have an accurate means of measuring qual- ity as perceived by subscribers. In an effort to fulfill these requirements, operators have various t raditional channels for gathering information. One channel is the collection of “fixed side” data, from the Operations Support System/Network Management System (OSS/NMS). This data is necessary but is generally used only for statistical analysis; without detailed processing, OSS data is limited when it comes to QoS evaluation and the end-user’s experience. Another source of network information comes from the operator’s own Customer Care department. While this is certainly a valuable source of data about network problems, it, too, is limited. Very few subscribers will call a Customer Care center when they are having problems. The rest may not complain, but they will be more likely to switch to a competitor. In addition, ...

- Page 5 TEMS ™ AUTOMATIC 8.1 What do you get with TEMS Automatic? ▪ Insight into the end-user’s perception of the network, thanks to measurements taken in the air interface rather than in network nodes (where other monitoring tools are used). A faithful measure of the end-to-end quality is obtained both for voice and for data services. ▪ 24/7 measurements – without the cost of 24/7 staff. Every corner of the network is probed around the clock by autonomous data collecting units. The state of the network as perceived by subscribers can be fed back to technicians and modified at a pace approaching real-time control. ▪ Automated measurements – in the truest sense of the word. Not only test calls and measurements, but also data uploading and system configuration are carried out automatically. This enables rapid feedback on the state of the network – almost in real time – to the entire organization, all the way from management to RF engineers in the field. ▪ Analysis and benchmarking with the aid of map, chart, and spreadsheet presentations of high-level statistics as well as individual routes. Operators, networks, or geographical areas can be benchmarked with respect to user-selected performance parameters. TEMS Automatic data can serve as input to statistical reports produced by reporting solutions supporting Microsoft OLAP and Microsoft SQL Server, such as ® ® Microsoft ® Excel and Microsoft ®...
- Page 6 TEMS ™ AUTOMATIC 8.1 MEETING NEEDS THROUGHOUT YOUR ORGANIZATION The vast amount of network data available from TEMS Automatic gives the operator the key to maintaining and improving network quality. TEMS Automatic analyzes collected data and presents the results in reports and presentations. These show where services are unsatisfactory, allowing op- erators to locate and fix problems before they start affecting subscribers. To analyze problem areas, operators can choose to use TEMS ™ Presentation to access TEMS Automatic data, TEMS Investigation data, or ™ TEMS Pocket data, and to present it graphically as statistics in routes or in ™ plots/bins of any shape. This makes it easy to see the network’s Quality of Service, while also allowing operators to find the cause of any problem. All measurements and events (radio parameters, signaling, etc.) of each single conversation, from call setup to call end, can be presented on a map, in a spreadsheet, in line charts, and in information windows. All views are linked together for maximum benefit. TEMS Automatic benefits all levels of the operator’s organization. Reports and other information can be distributed throughout the organiza- tion to show in detail what the current network situation looks like.
- Page 7 TEMS ™ AUTOMATIC 8.1 ▪ Marketing staff can extract statistics on coverage, services, and customer usage, thus furnishing the basis for precisely targeted advertising campaigns. ▪ Customer Care representatives can view reports that give them an idea of which problems occur in the network in various areas. They can understand coverage and available services as well. All of this i nformation can be used to better answer customer questions and a ddress c oncerns. ▪ Network Operation staff can monitor network services and receive SNMP alarms for non-working services. TEMS Automatic is an autonomous system ™ that uses in-vehicle, fixed location, or handheld test probes. It sends network information back via the air interface to a central server for analysis and report generation.
- Page 8 TEMS ™ AUTOMATIC 8.1 AUTONOMOUS NETWORK MONITORING Because TEMS Automatic relies upon device-based measurements, it truly tests from the user’s perspective. It monitors the radio interface, and conducts end-to-end voice and data testing. It is unattended and operated remotely, freeing operations personnel from routine drive testing while providing more network data than directed drive tests can. It provides multi-technology support in a single platform, and can test competitors’ networks along with the operator’s network, for accurate comparison. TEMS Automatic is designed to collect huge amounts of data from the network with minimal human effort. The system is objective, and collects and reveals network quality independently, no matter who the infrastruc- ture provider(s) may be. A variety of test units, including mobile Remote Test Units (RTUs), handheld test units, and fixed RTUs, are deployed throughout ...
- Page 9 TEMS ™ AUTOMATIC 8.1 Quality measurements TEMS Automatic measures uplink and downlink voice and data s ervices end-to-end from the user’s perspective. This gives operators control over the quality they are offering, as well as the ability to track down network weak spots. Measuring KPIs allows impartial comparison of different net- works. Together with these KPI measurements, the system also supplies i n-depth technical measurements that give a perfect foundation for analysis and problem solving. Data quality Data service performance measurements are performed on the air interface layers (RLC/LLC), and in the application layer (TCP), by measuring ...

- Page 11 TEMS ™ AUTOMATIC 8.1 Speech Quality Index also assesses speech quality as perceived by a mobile station user, and is computed by an algorithm that mimics the prefer- ences of participants in standardized listening tests. The SQI values are based on bit error and frame erasure rates and their respective distributions, as well as handover events, DTX percentage, and the choice of speech codec. SQI is expressed in the MOS scale. TEMS Automatic also now supports AMR-WB. C/I measurements TEMS Automatic can also measure C/I, another important parameter when assessing radio network performance. C/I is the ratio between the signal strength of the current serving cell and the signal strength of interfer- ing signal components. C/I is measured in real time in idle, dedicated, and packet mode, and can also be measured in frequency hopping networks. The measured average C/I can be presented for each frequency used, and this data makes it possible to identify frequencies exposed to high levels of radio interference. Frequency scanning Using the handset, the RTU can perform both GSM and WCDMA scanning. In GSM scan mode, the handset can scan any channels including BSIC decoding. In WCDMA scan mode, the handset can perform CPICH scanning on up to 12 carriers (UARFCNs), as well as request layer 3 decoding. It is also possible to connect an external scanner and have the data uploaded via the RTU.
