Real-Time, Multi-Technology, Multi-Vendor HetNet Orchestration

To meet the subscriber demands of today and tomorrow, operators introduce new radio equipment and deploy not only a mix of radio technologies (including both cellular and Wi-Fi), but also a mix of backhaul topologies and a mix of cores. With this heterogeneous mix of network components, HetNets require elasticity and programmability, dynamic policies for content and subscribers, and network resilience. All of this drives up the cost and complexity of network installations and maintenance. With network densification increasing in order to accommodate for additional capacity, there is a need for multi-technology and multi-vendor orchestration solution that can reduce both cost and complexity of network deployments and management.

Nominated by the Network Intelligence Alliance as the Best Technical Platform based on Network Intelligence for SDN/NFV, by Leading Lights as the Most Innovative SDN Product Strategy, by LTE Awards for Best LTE Core Network Product, and placing 3rd in CTIA’s eTech Awards for Wide Area Network (WAN) category, HetNet Gateway (HNG) from Parallel Wireless is a 100% 3GPP-compliant SDN- and NFV-based carrier-grade network orchestrator that unleashes a dramatic cost advantage while enabling operators to both scale and grow their multi-vendor multi-technology (3G, 4G, and Wi-Fi) networks. Read the ThinkSmallCell white paper on “HetNet Orchestration: The fourth dimension for wireless capacity growth”.

HNG uses standard interfaces to unify real-time, multi-technology, multi-vendor RANs, presenting them as one common interface to any vendor 3G or 4G core. This allows hundreds of nodes or APs to be abstracted in a similar way to VMware to allow hundreds of servers to be managed as an abstraction. The HNG readily fits into existing or greenfield networks between the RAN and the packet core, and abstracts the RAN on any COTS hardware while making the RAN self-configuring, self-optimizing, and self-healing.

Radio access-independent, the HNG solution supports multiple radio access technologies with virtualized gateway network functions (VNFs), as well as real-time multi-technology SON and multi-technology C-RAN. With the HNG, Parallel Wireless is committed to helping mobile operators solve today’s spectrum and radio resource challenges, while extending network investments and significantly reducing the cost to deploy or maintain unified HetNets. By utilizing virtualized DPDK fast path – with accelerator – the HNG solution offers plenty of capacity for high network performance.

HetNet Gateway Components

Multi-Technology Virtualized Gateway Functions

In order to orchestrate the network and unify the multi-technology, multi-vendor RAN, HetNet Gateway takes a unique approach to virtualization with native NFV and SDN for programmability and automation.

The HNG supports the following ETSI Open VNF-based virtualized gateway network functions for 3G, 4G and Wi-Fi:

• Supercell/Virtual-eNB
• Enables 3G/4G/Wi-Fi real-time network SON
• X2 Gateway
• Small Cell gateway/HeNBGW
• HNB Gateway/Virtual RNC
• Security GW
• Wi-Fi Controller/Gateway (TWAG, SaMOG,ePDG)
• Unlicensed Assist Backhaul (SDN)

The HNG presents hundreds of 3G/4G base stations or APs as one “Supercell” to the core, optimizing handover, paging, and signaling. It also virtualizes trusted and untrusted Wi-Fi functionality via ePDG and TWAG VNFs as a part of overall unified virtualized architecture. HNG also acts as an IoT and eMBMS enabler.

All these functions interwork with one another, instead of operating in individual silos, to deliver agility and flexibility across the network.

Multi-Technology Real-Time Network SON

HNG includes a built-in multi-technology SON that gives real-time visibility into 3G, 4G, and Wi-Fi traffic to provide self-configuration, self-optimization, and self-healing capabilities. It makes real-time load balancing and resource optimization decisions across the network.

The HNG acts as an any-AP/node unifier/orchestrator, anchors the traffic, and handles any mobility handoffs locally. This results in seamless handoff for the wireless users as they switch between different technologies indoors and outdoors

This real-time SON also allows for easy network expansion with new eNodeBs being plug-n-play in an active network.

Real-time multi-technology SON on HNG also provides self-healing benefits with dynamic traffic rerouting in the case of node failures or network congestion.

Virtualized Multi-Technology (3G, 4G, Wi-Fi) C-RAN

HetNet Gateway also includes a virtualized multi-technology (3G, 4G, and Wi-Fi) C-RAN functionality. Parallel Wireless C-RAN architecture is unique because it leverages standards based X2 interfaces for scheduling as well as provides real-time SON.

By using open interfaces it gives operators flexibility to choose any vendor for RAN.

By taking advantage of Moore’s Law for baseband chips, this multi-technology C-RAN allows to use low-cost System on Chip (SoC). This enables our solution to keep BBU functionality on site instead of it being centrally pooled. This permits operators to take advantage of any type of backhaul (Ethernet, fiber, wireless, etc.) without relying on latency-laden and expensive fronthaul.

By virtualizing both gateway functions (C-RAN and real-time network SON) on the same platform, HNG creates a coordinated system that provides centralized and elastic scheduling over X2.

The result is real-time load balancing across different radios for improved network performance and better user experience.

The HNG reimagines RAN economics by abstracting different radio technologies, core network interfaces and different vendor RAN equipment, and by providing self-configuration, self-optimization, and self-healing for any market or vertical: urban/dense urban, rural, enterprise/specialized enterprise, or Public Sector (Public Safety, military, public transit). HNG is a platform that delivers the high capacity, high availability and high performance required by today’s 3G and 4G networks, and is readily upgradeable to respond to evolving 5G radio networks.

Parallel Wireless has successfully completed interoperability testing (IoT) of the HNG through the Small Cell Forum Plugfest program with leading RAN and EPC vendors and more IoTs are currently in progress.
