Imagine a scenario where you had to reduce investment in your network infrastructure due to stagnation in revenue caused by increasing competition and flat rate tariffs. Sound familiar? One would most likely witness congestion in various parts of the network, triggering complaints and inevitably contributing to the churn of one’s subscribers.
To varying degrees, this is happening to operators who have not managed subscriber Quality of Service (QoS) as the levels of network traffic throughput increase exponentially. Infrastructure investments rarely, if ever, keep up with the increase in traffic. Enter Procera’s PacketLogic! Congestion management is no longer a daunting prospect and we are able to help you turn a loss into a gain.
PacketLogic provides a congestion management solution based on congestion data supplied by the operator. Prior to real-time RAN Awareness in the core network, we had been using congested cell lists to apply policy on congested cells based on trending data of cell congestion. Based on information from the OSS systems, we were able to identify which subscribers start their sessions in these congested cells and apply various policies for such subscribers. This is slightly crude since we did not get real-time updates for cell changes or real-time congestion information. This is where our new RAN Perspectives product will close the gap and make this an end-to-end network aware congestion management solution.
RAN Perspectives will allow our customers to know how many subscribers are in each cell, what their RAN signal quality is, RTT and TCP retransmission percentages while also providing throughput values so that RAN-aware congestion management can be applied to these subscribers. Through the PacketLogic platform, the customer will have a heat map of congested cells, applications used in these cells, number of subscribers and throughput averages. It will be possible to pinpoint issues in the network thanks to the way in which the information on the map has been visualized.
Having a congestion management solution provides customers with the ability of controlling congestion especially at peak periods, allowing for reduction in hardware and new site investment, while also addressing subscriber churn. Some of our existing customers were selected as the best mobile broadband network in the country in which they operate thanks to their existing PacketLogic congestion management setup. This was before deploying the RAN Perspectives solution into their PacketLogic platform. Their subscribers now get much better QoS because they get a fair share of the bandwidth and use of policies to help optimize video and mission critical traffic. They will benefit even further with RAN Perspectives.
It has been extremely rewarding to be in the field and able to help our customers help provide better QoS for their customers.
