Automated Mobility Management (RAN Testing)

Solutions_Lab_RAN_Testing

Mobility management testing involves assessing the effectiveness and efficiency of mobile network systems to ensure seamless device handovers, optimal connectivity, and user satisfaction.

With ATF we provide you a tool that is perfectly designed for that covering a wide spectrum of mobility test scenarios, including inter-system handover, intra-system handover, SRVCC, 5G dual connectivity verification, and more encompassing Voice over LTE (VoLTE), Voice over New Radio (VoNR), and OTT voice services. Using attenuators and shielded boxes we simulate various coverage scenarios executing the tests on real smartphones and providing Layer3 radio analysis.

Emergency Calling

Solutions_Lab_Emergency_Call

Emergency calls are vital for saving lives and ensuring public safety by connecting individuals to critical services in case of accidents or during crises. The call needs to be routed to the closest PSAP (public safety answering point) where human beings are responding to the call. Beside standard emergency calls between human beings and police, fire, or medical services there is the so called eCall which is a European initiative to reduce response times for automotive accidents, and it has served as a guideline in various countries worldwide in the meantime. An eCall-equipped car automatically dials an emergency numberin a serious road incident. It gives emergency operators information relating to the incident, including GPS coordinates, the time of the incident, and the vehicle identification number. 

Emergency calls must work regardless if legacy or brand-new technology is used, if calls are CS or PS based and independent from the end user device. Hence support of fixed phones (PSTN, SIP) as well as mobile phones (2G – 5G) is required. As certain intelligence is provided by the phone (e.g. AML – Advanced Mobile Location) testing with real smartphones and different OS versions is mandatory. For eCall special devices supporting that function need to be used 

SEGRON’s test suite for emergency call verifies the availability and performance of the service on real mobile over 2G, 3G or VoLTE networks. Additionally, a proper CLI handling, short Call Setup Times and excellent Voice Quality can be checked.

Regression Testing

Solutions_Lab_Testing_Regression_Testing

Regression testing in mobile networks is key to ensure the robustness and reliability of constantly evolving telecommunications systems. By systematically retesting modified or added functionalities, regression testing safeguards against unintended consequences, identifying and rectifying potential issues before they impact customer experience. This iterative testing approach enhances software quality, validates the compatibility of new features with existing functionalities and hence maintaining the stability of all services. 

Using SEGRON’s Active Testing Solutions regression testing can be fully automated by executing in fast and reliable way a set of predefined test cases which were designed to cover the complete core & radio network for all available network domains in combination with latest devices.

5G, Network Slicing & Latency

Solutions_Lab_Testing_5G_Network_Slicing

The introduction of 5G networks brings unprecedented benefits, including faster data speeds and lower latency. However, it also increases complexity. The intricate architecture of 5G, with its use of diverse frequency bands, advanced technologies like Massive MIMO, and complex network slicing, amplifies deployment and management challenges. The denser network infrastructure required for 5G further complicates maintenance and troubleshooting. Additionally, the integration of diverse technologies such as IoT and edge computing as well as multi-vendor based networks due to ORAN technology heightens the overall complexity. All that leads to an increased need for end-to-end and interoperability testing.
SEGRON’s solutions are able to orchestrate automated testing via one a single platform covering all relevant 5G capabilities using real end customer devices. Based on our powerful Layer-3 tracing solution we can verify the correct parameter settings and messaging flow according to 3GPP standards, for both 5G NSA and SA (VoNR).
Of course, also the verification of network slices, download speeds and low-latency scenarios (eMBB, URLLC & mMTC) is covered.

Legal Interception

Solutions_Operations_Live_NW_Live_Legal_Interception

Legal Interception is a very sensitive and critical area, as MNOs are obliged by law to deliver communication data from suspects involved in crime and terrorism, which is getting a bigger and bigger problem in the last decade. Incompleteness of data can lead to high penalties for the communication service provider, which can be easily avoided by using a proper testing solution.

SEGRON’s Active Testing Solution can help to verify and monitor to the correct functionality of legal interception services by using real end customer profiles and devices.
Gaps or incompleteness of data within observations can be detected immediately and data loss avoided.

Live Network Monitoring

Solutions_Roaming_Live_Network_Monitoring

Our innovative testing approach enables live network testing and service verification for mobile voice and data services, including Voice over LTE (VoLTE), Voice over New Radio (VoNR) and OTT voice services.
Based on our comprehensive Access, Voice, Data & Messaging KPIs, you can ensure the correct functionality and integration of your most important services, while related radio interfaces can be analysed using the Layer3 radio analysis.

As we are using real end customer devices for our tests you will automatically get the  information about the correct functionality on one side and the customer experience (QoE) on the other side

Campus Network Testing

Solutions Industry IoT Use Case_Campus Network Testing

A campus network forms the basis for mobile communication in industry environments. The operation of the local infrastructure with higher bandwidths and extremely short latency times must be ensured accordingly.

This is because reliable, fast and secure data transmission is critical to the success of many IoT applications.

Employees and guests also receive significantly better reception for voice and data communication via the campus network. In addition, external service providers and suppliers can also connect via the public network meaning that 5G campus networks therefore form the basis for mobile communication within the industrial environment.

Corresponding regression tests are therefore a very important component to ensure the operation of a campus network. Test must be carried out regularly after changes to the infrastructure or software changes of IoT modules, network components or user equipment.

SEGRON can help you to ensure the proper network and service functionality, which is building the basis for the communication of people and 
machines and thus ensures successfull and failure-free production.

Smart Factory Monitoring

Solutions Industry IoT Use Case Smart Factory Monitoring

Typical smart factory require 5G connectivity to control robots and self-driving automated guided vehicles (AGVs) in production lines, the use of augmented and virtual reality for visual inspection in smart factories and the use of numerous sensors for automated inventory control and supply chain management in smart warehouses.

Many wireless connections are required on the factory floor to ensure extremely reliable & stable coverage and connectivity with ultra-low latency, excellent downlink and uplink data rates.

SEGRON’s Automated Testing Framework (ATF) supports the early detection of problems such as broadband noise caused by machines and other radio signals that user devices are typically exposed to in highly complex environments. Quick detection of interferences that could accumulate in the network, help to avoid quality of service (QoS) issues that could cause operational impacts and downtime within your production lines.
