Independent Trials show GoS 360° Solution Significantly Reduces RAN Signaling Load

Written by GoS on . Posted in Blog

The GoS 360° Solution has been subjected to a range of tests by Ingenia Telecom, in conjunction with a leading mobile operator. The results demonstrate that the GoS 360° Solution significantly reduces signaling load in the RAN and promotes RNC load-friendly behavior. The results were presented at the recent IEEE Communications Quality and Reliability Workshop in front of an audience of industry and academic representatives.

The testing proved that, when compared with over configurations, the device with GoS installed performed the lowest number of Radio Bearer reconfigurations and remained in low energy states for longer periods of time. Depending on the configuration of the mobile network, this strongly suggests that the GoS 360° Agent has a positive effect on battery duration and life expectancy.

Reducing signaling load and radio resource consumption and transitions has important consequences for user experience and network capacity planning. As has been demonstrated in live deployments, the GoS 360° solution can help MNOs significantly reduce CAPEX and positively impact user experience. The independent analysis also indicated that GoS 360° is compatible with other solutions and can provide significant benefits when deployed alongside them.

A summary of the methodology used, the tests and the results is now available. It can be downloaded here.

Extending the PCC Framework for Device Based Policy Enforcement. #PolicyControl #Telecom

At the recent Policy Control and Real-time Charging event in Berlin, Alex Harmand, from the Group CTO office of Telefonica presented a view of the future needs for policy evolution and gave an idea of where he thinks it’s headed.

Among other points, he suggested that there was a need for local caching of content on devices, rather than in the CDN. Such caching would be controlled by a local policy enforcement point, deployed on smart devices. We’ve heard this view before, but it’s interesting to see it discussed in a public forum. The rationale behind such caching is to enable operators to download more content at off-peak hours, so as to help spread network load and alleviate potential congestion during busy hour periods.

In such a model, users would effectively be subscribers to a particular movie or television programme and would be delivered the content ready for them to access when they like. Of course, the idea suggests different models for charging. For example, a user could pay a normal subscription for such a delivery method, but a premium if they want something more immediately – in other words, those who can’t wait could be offered the chance to jump the queue on payment of an additional fee.

On the other hand, this model also enables to the network operator to offer policy capabilities to third party content and CDN providers, further extending the possibilities that the evolving policy framework can offer. Being able to control policy on devices while remaining integrated with the network policy function clearly delivers advantages here.

What’s interesting is that some of the things we’ve talked about in laboratory discussions are coming more and more to the fore. We see a great fit for this and many other use cases but it all depends on ensuring there is a single, extensible architecture from the smart device to the PCRF and charging systems. Once in place, the same platforms can be used to support an increasing variety of use cases.

Of course, the models need to be worked out in more detail, but the role of device based policy enforcement is critical to this. It opens up a range of applications and we’ll comment on some of these novel areas and use cases in future posts.

The Interesting Thing About Mobile Data #PolicyControl #Telecom

Much of the research published about mobile data tends to focus on the predicted volume that is expected to be demanded by users. While there is some disagreement on the absolute numbers, there is a solid consensus that it’s going to be large. Of course the interpretation of this varies. One recent report has provided useful insight, which points to an area that MNOs will have to address.

According to industry analysts Juniper, 60% of mobile data traffic will be carried, not by conventional mobile networks, but by WiFi . The network of tomorrow will be a mix of LTE, legacy technologies such as 3G, and a diverse set of small cells that leverage WiFi and related technologies.

This means that MNOs must increasingly consider how they will route traffic in their network. Until now, users have often unilaterally selected WiFi access to obtain faster download speeds, avoid costly roaming charges, or to bypass their plan limits. This manual selection has the result that they typically leave their MNO’s network for a competing WiFi solution where one is available.

By deploying a greater mix of WiFi, small cells and macro cells, in other words, moving to heterogeneous networks, MNOs will increasingly include alternative access technologies as part of their offer. This will help them retain customers and fully leverage their investments.

But, to ensure that users leverage these, MNOs need to help them in network selection. They need to be able to seamlessly connect users to the best available network and to do so selectively, based on the demands of different applications and traffic types.

This is where the ANDSF comes in. It’s early days for this new(ish) entity, but it is likely to assume a central role in future networks. Juniper’s research implies a significantly increased role for the ANDSF, as something has to manage the selection of the most appropriate access technology and this is the most likely solution.

It’s not going to be sufficient, however, to simply deploy centralised ANDSF solutions. MNOs will need to extend ANDSF and TDF functionality into mobile devices, to ensure that traffic management and access network selection decisions are made according to local conditions and demands.

The network is evolving and migration to LTE will lead to many changes. But headlines about the growth in mobile data traffic don’t tell the whole story. MNOs need to consider the likely mix of data traffic on their network as well as the kinds of applications that drive it. This level of detail will help them determine the appropriate mix of access technologies in their (heterogeneous) networks. MNOs will need to explore how a distributed ANDSF architecture can help them achieve optimal traffic routing. Device-based ANDSF solutions will complement those in the network, helping deliver the best customer experience and ensure that users stay connected to the MNO network.
