Switching their strategic focus from customer acquisition to revenue and margin development, telecommunication operators in highly competitive mature markets are pressed to develop new services to retain their customer base while increasing revenue. Innovative offerings such as video and file sharing, video conferences and message services, integrated communication and other mobile office functionalities for business users have emerged. At the same time a strong monitoring process for operational cost control and compression is mandatory. In such a scenario, Quality of Service (QoS) management has become mission-critical for network operations that must meet stringent QoS targets and Service Level Agreements (SLAs) on an ever-expanding portfolio of services. Quality of Service is a consolidated indicator that is closely related to customer preferences, particularly in the business segment. Automatic E2E testing can play an integral role in overcoming this challenge, being powerful to handle complex services scenarios while at the same time agile enough to adapt rapidly to new services offerings. ANTS is a proven solution enabling Telecom Operators to implement agile and industrial operations to verify Service Quality via End-to-End testing enriched with CDRs, Logs and Counters analysis and verification.
A huge amount of raw data are gathered providing a real and fully integrated view of information mined from various sources and the capability to analyze those information from different perspectives:
Quality of Service
CDRs, XDRs Logs and Counters in combination with E2E tests are a rich data source to evaluate the offered QoS to the complete customer base. Using the information extracted from this data, the solution provides analysis on Usage, Performance and Faults with reference to reasons and explored by Network Elements and over the time.
Usage Analysis
Extraction of statistics on network usage, failures based on network element topology. Mobile types usage reports for strategic marketing decisions. Peak/off peak traffic analysis with critical path identification.
Fraud Detection
We're on a mission to change the way the housing market works. Rather than offering one service or another, we want to combine as many and make our clients' lives easy and carefree. Our goal is to match our clients with the perfect properties that fit their tastes, needs, and budgets.
The solution is based on a unique integrated environment of Business Intelligence and Big Data, allowing the users to autonomously create reports, analysis and dashboard.
Service Assurance
A competitive advantage, if quality and reliability are guaranteed
The ANTS for Service Assurance End-to-End testing solution enables operators to verify the QoS delivered by their network and service infrastructure. Tests are available from pre-built libraries or designed by the Users with ANTS graphical Test Procedure Editor without needing knowledge of the infrastructure topology. With a few clicks, tests can be instantaneously run or scheduled for a later date, once or periodically, on a subset of network elements and user profiles. The scheduling and resource management engine then seamlessly coordinates the execution across the Remote Test Units (RTU) deployed throughout the network in all the needed locations.
All call destinations (inbound, outbound) and services including Voice, SMS, video, Web navigation, contents download/streaming and IVR/VAS are supported on home and roaming networks with all access technologies (GSM, GPRS, Edge, UMTS, 4G+, 5G and PSTN, ISDN, LAN, WiFi, etc.). New service testing is enabled by the Remote Test Units (RTU) including VoLTE, VoWifi, RCS and 5G networks reproducing customers’ real-life use conditions.
Any user profile, postpaid and prepaid, including visitors in roaming areas, can be tested – simply choosing predefined SIM categories when planning a test. The centrally located SIM/USIMs will be virtually dispatched to the appropriate RTU when required.
End-To-End Testing
Performance Indicators
The test progress is displayed on an animated flow chart, including the measures collected (check points, counters, timers) and traces generated.
Standard and user-defined Key Performance/Quality Indicators (KPI/KQI) are evaluated on collected measures including Service Availability, Accessibility, Integrity, Retainability.
Alarms are raised when KPI/ KQIs exceed specific preset thresholds.
Test results are also available offline for many different interactive analyses using ANTS BI dashboards to diagnose potential issues and produce reports that monitor the actual QoS performance against engagements towards customers, partners (e.g. roaming partners), or regulatory authorities.
Via the air interface, all Public Land Mobile Networks (PLMNs) accessible by the deployed RTUs can be tested, thereby supporting competitive benchmarking.
