Abstraction of Access and Core

Features and Capabilities

Parallel Wireless OpenRAN Solution helps operators cost effectively roll out new cells and manage coverage and capacity of existing nodes by reducing complexity between RAN and the core sides of the network with abstracting RAN and core sides of the network with “many-to-one-to-many” approach:

On the RAN side of the network, the software virtualizes existing cells into a pool of virtualized resources that can be allocated dynamically. It virtualizes thousands of base stations to look like a few virtualized “supercells” to the core. This capability allows operators to expand their RAN for additional coverage and capacity without putting any additional strain from signaling on the core components. This capability allows the software to aggregate S1 and X2 interfaces from the nodes under its management. This aggregation allows anchoring of all the traffic for seamless handoffs between 5G, 4G, 3G and 2G technologies. The solution uses all 3GPP standard interfaces to communicate to nearby 2G, 3G, 4G, or 5G macros: standard X2 interfaces to communicate with nearby 4G macros; as a virtual RNC, uses Iu-CS and Iu-PS interfaces to communicate with MSC and 3G packet core. The software uses this collective information to mitigate interference. Open RAN Solution is able to make real-time decisions based on its direct position in the signaling and data path and interworking of various multi-technology virtualized gateway functions. It also handles mobility and session continuity across UMTS, LTE, or 5G with local anchoring on the Open RAN Aggregator.
On the core side, the software virtualizes multiple cores into a pool of resources for the multi-technology RANs and presents them as standard interfaces to packet core. By aggregating multi-RAT traffic, the software enables signaling reduction towards the core and mitigates any signaling storms. By virtualizing core towards the RAN, Open RAN aggregator allows operators to deploy multiple packet cores, support MOCN, optimize IoT traffic, and provide more profitable MVNOs offerings.

This capability is designed to handle deployment challenges from building a new network, to scaling the network, to filling coverage gaps that traditional network architecture is not designed to handle – all at a lower cost.

In addition to being able to handle 5G, 4G, 3G, 2G RAN functionality, the Solution would be able to support multiple 5G network architecture deployment options simultaneously. Each gNodeB can be configured to work as an en-gNB for NSA or as gNB for SA. Intelligent algorithms in the software platform can handle routing of signaling and data from each eNB/gNB to the required EPC/5GC. The intelligent algorithms are also able to provide slicing like functionality to legacy 2G/3G networks as well as 4G.

Slicing helps to support new use cases and differentiated experiences including private networks and will be a source of new revenue for the mobile operators.
