User plane monitoring is not only important and useful for technical purposes, but can also help generate additional revenue for MNOs. The flip side of the coin is the price and complexity.
Monitoring user plane in LTE networks poses the following challenges:
The above applications can be performed with Cubro Probes and the EXA32100. The combination of these two devices reduces the overall costs while enhancing the performance and efficiency for those customers who have an existing control plane monitoring solution. Several major MNOs use Cubro’s solution to add user plane monitoring capabilities and to off-load any existing control plane monitoring.
This solution allows for filtering and monitoring only specific users/devices rather than monitoring all user plane traffic in its entirety. Filtering on a particular customer in a highly loaded LTE network is both difficult and expensive, however, Cubro offers solutions that maximise return on investment. Utilizing the advanced features of the Cubro EXA32100 and EXA48600 platforms, in combination with EXA24160 and the technology in the Cubro probes, the user has a powerful solution to address these issues. Cubro offers a combined solution for IMSI filtering on heavily loaded networks that has a track record of customer satisfaction and reduction in the costs of monitoring.
Cubro G5 devices (EXA32100 and EXA48600) are the only network packet brokers on the market capable of filtering on the inner IP of a GTP tunnel in hardware and at full line rate.
Cubro offers the most cost-effective solution:
A simple and scalable solution to offload irrelevant traffic from the probes and reduce costs.
Cubro offers a high-performance solution for the best value:
In this application the user plane traffic is first load balanced by the EXA32100; the control plane traffic is then broadcast to all units. Next, the EXA24160 does the correlation and IMSI filtering. The output is the correlated control and user plane for the specified (filtered) traffic.
