Agile Interworking: Protecting Investments by Connecting Legacy Services to IMS and LTE Networks

Download the solution paper now!

SS7 has long been established as the primary signalling protocol used in today’s fixed and mobile networks. As such, operators are asking the question: how can we connect our services to an IMS-based or Diameter-enabled network from legacy infrastructure?

The solution comes from the deployment of specialist, custom solutions that solve individual problems and collectively provide a platform for incremental future network evolution. The Squire Technologies 3GPP compliant SVI_IWF (Interworking Function) enables legacy solutions to be extended to LTE and IMS networks, with flexible deployment options, customised interworking intelligence, and providing the foundation for a step-by-step approach.

What you’ll learn from the solution paper:

  • How to safeguard your portfolio of revenue-generating legacy services
  • The importance of the Diameter IWF

SS7 to Diameter – A new challenge for operators

Interconnection specialists Squire Technologies launch new SS7 to Diameter interworking function solution, helping solve interconnection challenges between legacy and NGN platforms.

Interworking between different networks and systems is a constant thorn in the side for operators. Even if everyone adopts the same protocol, there can be differences in implementation. To enable these systems to communicate and exchange information and to support efficient service delivery, protocol conversion and interworking must take place.

SSEvery network and operator infrastructure is different. Vendors may implement standards in different ways – such differences may be perfectly permissible and different operators may choose to follow different versions of standards. Heterogeneity is the norm, despite the enthusiastic adoption of standards around the world.

The advent of LTE is adding to this problem as it uses an entirely different set of core standards for the control of signalling and subscriber services. Instead of the long-established SS7 signalling that is used in 3G, 2G and fixed networks, LTE uses Diameter signalling to perform the same functions. That’s great, but it means that such networks must be capable of interoperability with networks that support legacy SS7 signalling.

This problem is known and has been addressed through the development of an interworking specification between SS7 MAP and Diameter (3GPP TS 29.305). This provides a template for ensuring compatibility between common SS7 interfaces and their Diameter equivalents, as well as accounting for specific differences in the data conveyed.

We have a long history in implementing and deploying interworking solutions, helping operators to overcome network incompatibilities and to ensure subscribers can access different services in different circumstances – for example, when roaming into new networks or when dropping out of zones covered by one technology (e.g. LTE) into a legacy domain (e.g. 3G).

That’s why we have launched the SVI_IWF, a fully compliant 3GPP SS7 to Diameter interworking function. It’s a high-performance implementation that can be deployed as a standalone device or as an extension to an existing Squire Technologies’ solution.

If you are confronted by interworking challenges, we can offer a solution – ensuring that your subscribers obtain seamless service and that you address new and emerging needs. Our expertise means that operators that need to interconnect Diameter-compatible solutions with legacy platforms can do so confidently and with the knowledge that we can also cope with the unique circumstances of each case. Our SVI_IWF is a turnkey solution but we can also rapidly customise it to adapt to different demands.

At Squire Technologies, we know the value of standards – but we also understand the demands of a heterogeneous world. This means we can ensure we deliver proven solutions that are tailored to your specific situation. If you need help in interworking SS7 to Diameter, why not get in touch to see what we can offer?

ITW – Wholesale Rebound and the Continuing Need for SS7

At ITW last week in Chicago, there was a real buzz around the topic of wholesale. Wholesale is often overlooked in comparison to other, trendier topics, but there’s no doubt it’s a fundamental part of the industry. Operators and service providers need to collect and receive traffic from different destinations and, to do so, they need relationships with carriers who can transit minutes around the world.

There’s a lot of arbitrage and negotiation, of course, and the industry tends to be overlooked, particularly as price sensitivity can reduce margins. However, at ITW, we saw a tremendous degree of activity, confirming that wholesale is actually in good shape with not just an active pulse, but something of an upsurge.

Wholesale prices can go up, bucking the downward trend!

The reason for this is that, in some countries, regulatory pressure has actually increased prices, bucking the trend of downward pressure. This creates opportunities and many deals were struck. Alongside this positive surge, we were also taken with the countless conversations we had in which the importance of SS7 to future operations became clear.

SS7 interconnect remains essential as a stable interconnection solution and to increase ROI

While many regard SS7 as the legacy, in reality, most carriers we spoke to are committed to maintaining their SS7 interconnects and also extending their base to support connectivity with more providers. Why?

Well, the answer is clear. It’s all about stability and return on investment. First, most national operators are maintaining SS7 as an interconnection protocol for the simple reason that it works. It’s stable, reliable and well understood. Second, the deployed base has already been paid for – so naturally, national operators and carriers want to leverage existing assets in order to boost profitability.

While SIP is an option for some, there are still uncertainties regarding investment in SIP as a national interconnection solution: for many SS7 remains the preferred choice. This means that carriers need to maintain and extend SS7 interconnection points with national operators while at the same time delivering traffic internationally across VoIP routes – so they need reliable platforms with proven SS7 capabilities but which can also deliver traffic across VoIP interconnection points.

Carriers need cost effective, proven SS7 solutions, delivered through innovative software-only solutions with dramatic cost savings over legacy platforms

But they also need to conserve costs and ease deployment. That’s why they need software-based solutions that enable both SS7 and SIP interconnection, with a host of national approvals and a simple, cost-effective deployment model.
