Policy as a Service is Coming – But it needs to be End-to-End

Written by GoS on . Posted in Blog

One of the key themes addressed at the recent SDP Global Summit held in Rome last week was the potential for operators to offer APIs that enable control of network policy. Such APIs can be for internal use – to enhance service offers – or could be offered to a range of third parties.

A consensus emerged around the idea that network ‘policy as a service’ represents a unique asset that can be leveraged by operators. Since they own, operate and manage networks, they are in a unique position to control Quality of Services for applications and users.

A variety of business opportunities have been proposed – from using policy APIs to secure service level agreements for customers with demanding applications (think enterprise here) to offering the same APIs through secure gateways to OTT application providers without network assets of their own and which may wish to enhance service delivery for their applications.

But there is something missing from this discussion. While it’s necessary to expose APIs from policy server and to create an infrastructure to leverage what remain as unique assets, it’s not sufficient. What is needed is the ability to go beyond the physical boundary of the network and to take into account the experience and demands of the user, as well as local resources that are available.

That’s why operators intending to expose policy as a service capabilities – whether to internal users or to third parties – need to consider deploying Policy on the Device solutions. PoD solutions can provide real-time information regarding application demands and the QoS that is available. They can interact with policy control points to ensure that applications that require particular QoS levels are prioritised on demand. What’s more, they can also provide a means to selectively switch between different access networks in a mobile environment, depending on the best available connection option for the specific service or application requested.

Policy as a service makes a lot of sense. It leverages a core operator capability and competence but it is incomplete without taking into account the specific experience of users and their devices. In order to deliver policy as a service, it is essential to incorporate PoD capabilities. Why not talk to GoS Networks to find out how to deliver true end-to-end policy control and enable successful launch and effectiveness of policy as a service offers?

A Device-Based Solution for Managing Seamless Wi-Fi Offload from 3G / LTE Networks

Written by GoS on . Posted in Blog

Mobile data traffic continues to grow, but evidence shows that the rate of growth has slowed in recent years, principally as a result of Wi-Fi offload. This could become one of the biggest challenges facing the mobile industry. But, if managed in the right way, MNOs can transform this challenge into a proactive strategy that derives multiple benefits for both themselves and their subscribers.

Instead of passive disengagement, MNOs can become actively involved with Wi-Fi offload so that they can maximise the benefits to them and to their customers. Indeed, proactive Wi-Fi offload strategies can create additional economic and strategic benefits for all parties.

Wi-Fi has a clear role to play as part of a heterogeneous approach to network coverage. Such an approach not only includes Wi-Fi offload as an option for users, but also encompasses use of Wi-Fi Access Points (APs) to increase coverage more generally within cells.

What is needed to enable Wi-Fi to fulfil this role is an approach that combines the benefits of both Hotspot 2.0 and ANDSF solutions, but which also incorporates smart devices and enables these to become an active element in the network selection, handover and roaming process. Such an approach would recognise the fundamental need to make user experience central to access network selection.

The solution to this challenge is two-fold, and puts the point of control directly onto the device. First, decomposing the ANDSF allows a client to be deployed on the smart mobile device to locally manage access network selection in co-ordination with defined network policies. Second, the client should also be able to act as a Policy and Charging Enforcement Function to maintain and manage policies in response to locally monitored conditions and requirements, in turn acting as a local Policy Enforcement Point (PEP) on devices.

Wi-Fi offload is both a necessity for MNOs and a positive boon for subscribers. The work of the Wi-Fi Alliance and 3GPP has produced solutions that enable network selection to be automated and seamless with respect to users. MNOs can deploy this solution to facilitate network selection and immediately derive a range of economic and strategic benefits.

By deploying key elements (ANDSF and PCEF) on smart mobile devices, the user quality of experience can also be taken into account, enabling, in time, richer service delivery and a wider range of options for MNOs and hotspot providers alike. Wi-Fi offload should be a strategic element of MNO planning: the distributed ANDSF and PCEF solution from GoS Networks ensures that this strategic role can be fully captured and monetised with clear and identifiable benefits for all stakeholders.

Policy on the Device Continues to Attract Attention

Written by GoS on . Posted in Blog

There’s been a spate of news recently about the increasing importance of Policy on the Device (PoD) solutions. Operators are becoming aware that, in order to effectively deliver end-to-end policies and QoS, they have to extend policy monitoring and control capabilities to smart devices.

Just a couple of years ago, PoD was a relatively unknown area, in which pioneers such as GoS Networks were innovating advanced solutions that enhance the user experience, optimise service delivery and reduce operator costs.

Today, as Cassio Sampaio of Bell Canada noted, speaking ahead of this year’s Broadband Traffic Management Event, “Policy on the device will continue to gain traction and perhaps move past the “shiny demo” stage we are currently in. There is a clear space for an increase in the level of self-serve features to be provided to subscribers driving direct cost savings and potentially creating other revenue opportunities”.

We agree. PoD can solve both specific challenges – end-to-end service assurance, RAN optimisation as well as delivering side effects such as enhanced device battery life – but it can also provide a platform for a wide range of new services and capabilities.

This is an interesting time for the evolving policy segment. We’ve had policy 1.0, 2.0 and we think the next phase is coming. Once PoD solutions are widely deployed, they will enable and unlock new services that cannot currently be created or delivered. That’s why it’s so exciting. Operators need to think strategically – using short-term benefits that can be delivered today to enable a richer set of opportunities in the future.

Little wonder, then, that PoD is starting to attract such attention. Why not talk to us and find out how you can benefit today from innovative PoD solutions – and build a framework to enable future innovation? Or, check out the Yankee Group report on the subject by following this link.
