The present invention generally relates to the field of wireless communication. More specifically, the present invention relates to methods, circuits, devices, systems and functionally associated computer executable code to support edge computing on a communication network, such as a wireless access communication network.
Since 2009, when for the first time the volume of data traffic over mobile network exceeded that of voice traffic, mobile data has more or less tripled each year in volume thus taking over more and more of the mobile traffic in volume. In addition, machine-to-machine solutions are maturing throughout vertical industries and as the emerging number of wireless sensors (grow exponentially over the next 10 years) which are key enablers to many mission-critical scenarios, from smarter traffic to video analytics, the issue just grows. Wireless sensors are expected to grow in their numbers exponentially over the next 10 years. On the profitability side mobile data opens new revenue possibilities to the MNOs. A major obstacle standing before the MNOs is their inability to connect to the content thus suffering from the Over The Top (OTT) syndrome. In addition, many of the applications generate data that withholds inflexible requirement on the way traffic should be served over the network. In order to enable adequate user experience, the data must be supplied to the UE according to strict bit-rate requirements. Any deviations from these requirements automatically lead to lousy experience thus to the abandonment of this service by consumers. This leads to the need for a solution which on one hand will ensure enhanced user experience when consuming data while presenting new revenue streams to the MNOs, and on the other hand will not degrade the network behavior and will not lead to unjustified expenses for the end users. The solutions that are being driven to the market are around the mobile edge computing/cloud, where virtualized infrastructure/cloud is integrated into the mobile RAN, enabling deploying services at the edge of the mobile network. This creates a new challenge for operators as now content and application are being provided to end users directly from within the RAN, without the network core elements having any visibility of the data.
End users are enjoying ever improving wireless data access but this does not come for free. 3G/4G operators usually bill there end user based on the data volume they consume. Based on the standards, charging is performed inside the cellular network on a per-flow basis. In today's mobile networks, charging solutions receive the required data/information from the core elements.
A solution needs to be provided so that charging/billing, which is currently happening adjacent to the network core, will continue working transparently.
