Ensuring continuity and enhancing capabilities for automation of functional and performance testing of SS7, Diameter and HTTP/2.

Like many operators today, our customer — a leading pan-European MNO — runs a complex network environment across multiple countries, backed by international and inter-operator connectivity. This network landscape continues to grow in complexity, which means that maintaining, testing, and validating legacy networks, as well as continuing to innovate and offer differentiated services, is a challenge.

Until recently, the MNO had been using a legacy testing solution, NetScout’s Spectra2, to ensure the continued performance and security of its SS7 network. However, NetScout retired Spectra 2 on 30 August 2024, with an obsolescence/end-of-support date set for 2026.

Our customer needed a comprehensive, alternative, flexible solution that could not only replace the legacy test solution for one part of its network, but which could also provide the versatility to handle all challenges across these security domains, and address all vulnerability threats.

Emblasoft Evolver is a comprehensive, flexible test, validation, and active monitoring platform that supports all necessary SS7 interfaces over IP, including SCCP / TCAP (which is essential for SMS), and MTP (which is required for routing information and establishing connections between SS7 entities), and ISUP (for call control). Together with these, it also offers comprehensive support for Diameter, HTTP/2. It provides complete lifecycle testing and assurance, with agile service validation and active monitoring for 2G-5G networks and protocols.

How a European Tier 1 converged service operator used our platform to assure vIMS migration, and using it to comprehensively test, monitor, and actively assure RCS and VoLTE.

Migrating to virtualised IMS platforms is becoming essential for operators seeking to modernise their networks. But with this shift comes the challenge of validating performance across complex, multi-vendor virtualised environments — all while maintaining quality and meeting strict SLAs.

That’s why a leading European Tier 1 operator turned to Emblasoft Evolver to test, validate, and actively monitor its vIMS migration, ensuring seamless service delivery for millions of subscribers.

In this study, we explore three use cases – validation of a complete vIMS migration, and active monitoring (probing) of RCS, and VoLTE. It highlights the flexibility and scalability of the Emblasoft family of test and validation solutions.

Evolver is a single solution that offers automated service validation and assurance by emulating realistic user behaviours, different communication channels and devices, and different protocols to ensure continuous QoS and to test and validate new applications and services before and after launch, reducing risk and driving business opportunity.

How Emblasoft Evolver helped a multinational operator comply with emergency services call handling standards

The ability to handle calls to the emergency services is mandatory for licensed operators. Ensuring that this process works every time is essential – across all networks and for any kind of call made on the PSTN or PLMN.

With changing technologies, and the introduction of new architectures it's essential that operators can deliver these mandatory services and ensure that they are future-proofed for any new architectures or standards.

That's why a leading European operator, with a full national network, called in Emblasoft to provide the testing, validation, and assurance it needed to validate its obligatory emergency call management services.

With Emblasoft Evolver, operators can easily automate the assurance and validation of their emergency call handling services.
