Dyaptive Solutions

for Mobile Network Operators

With the evolution of 3G and 4G networks, and increased growth in data services, wireless network operators are faced with many challenges.

As increasingly advanced data and voice services are released, operators face increasing challenges maintaining service quality.  These challenges come from the high correlation between network performance, capacity, service quality and the load on the networks. Operators need to test the impact on performance and capacity of new features, services, software loads and network equipment. These tests need to be done before rolling the services out to customers.

DMTS testing systems let network operators speed service deployment, increase service quality and reduce the cost of problem resolutions. Dyaptive offers proven real-world traffic generation:

• Validate impact of new services at each stage from service planning through deployment to troubleshooting and field support
• Test new vendor infrastructure equipment under realistic network conditions
• Dramatically reduce time in understanding impacts of network configuration changes
• Plan networks to accommodate peak loads under adverse conditions

The DMTS system lets network operators increase testing capacity - with up to 2,400 Software-Defined mobile terminals per cabinet - by automating tests with repeatable, preset test cases and scheduling tools that allow tests to run unattended around the clock. Sophisticated logging, statistics capture and performance analysis tools enhance analysis of problem areas.

Functional Application Testing Under Load

Wireless network operators need to be able to characterize impacts from new services on network resources, as well as the impact these have on the Quality of Experience (QoE) for existing voice and data users.

Applications and services need to be tested under real-world traffic conditions. Whether the new service is creating the load, or is being introduced on a network that already faces load management issues for the existing subscriber-base, Dyaptive can help operators ensure a high QoE for all subscribers.

• Ensure higher quality of products:
• Find defects that would otherwise make it to market
• Logging of handset/terminal measurements
• Detailed KPIs captured across hundreds of SDR mobile terminals
• Bring services to market faster:
• Millions of calls/access attempts/procedures per hour
• Rapid modeling of multiple scenarios
• Test in ways not previously possible:
• Complex calling/access scenarios
• Randomized or coordinated mobile terminal behaviour
• Mix of real terminals and DMTS traffic

Vendor Verification and Interoperability

Infrastructure equipment from multilple vendors exists in operator networks . Often, these vendors are not able to test their released product using the operator's specific configurations. With releases coming from vendors more than twice a year, conducting complete and repeatable regression tests is challenging. Operators need to maximize the amount of time they can spend regression testing within the limited amount of time available to deploy new releases.

Dyaptive can provide operators with the ability to create multiple real-world load scenarios in minutes, allowing the optimization and tuning of the vendor equipment, and the benchmarking of multi-vendor RANs quickly. Use the Dyaptive DMTS to simultaneously connect with a variety of vendor basestations simultaneously and load to their maxima.

Dyaptive helps operators reduce outages and in-service reconfigurations by finding defects that would otherwise make it to market, and by predicting end-user experiences prior to field deployment.

Network deployment and optimization

Predicting the impact of network configuration changes is challenging. Testing configuration changes in live-air networks can be costly and logistically impossible. Operators need a method to both preview the impact of configuration changes, and to forecast the impact of subscriber growth on RAN performance.

Dyaptive helps reduce costs, avoid service interruptions and predict the impact of such load by allowing the verification of network performance under subscriber load without impacting paying subscribers. With the Dyaptive DMTS, operators can fine-tune network parameters and understand the impact of changes in traffic characteristics in the safety of the lab.

Special Projects and Emergency Planning

The impact of increased load on a wireless network that is already under stress is well-known by most wireless network operators. Recent global events have demonstrated the dramatic impact of perfect storm conditions: Massive network demand is placed upon wireless networks in time of emergency, when those network resources may be already under great stress, or experiencing localized outages. Even less dramatic events, such as major sporting events or gatherings can place demands on a network that requires operators to deploy temporary, mobile or emergency RAN infrastructure into the field.

Challenges such as these may be modeled using Dyaptive's DMTS. The DMTS can generate hundreds of thousands of voice or data access attempts per hour, creating worst-case conditions and maintaining them for hours or days. Operators can place this load upon RAN infrastructure then model worst-case scenarios in which RAN infrastructure is taken offline, or cycled under crippling load.

Dyaptive can provide operators with the peace of mind that comes from understanding exactly how their network will perform in the perfect storm.
