Huawei used Mobile World Congress to launch a number of solutions to improve the performance of mobile network including: a next generation single evolved packet core solution; a single radio controller (SRC); and looked to the future with its FusionNet concept for LTE-B.
The next-generation SingleEPC (evolved packet core) solution offers ultra-broadband advantages and is the only solution featuring 6-mode atom-level convergence to support a convergent PS core for multiple radio access modes, including GPRS, UMTS, LTE-FDD, LTE-TDD, CDMA and Wi-Fi. The solution supports the dynamic implementation of traffic models for 6-mode access technologies and optimises PS core network resources.
The SingleEPC solution enables 64 times more signalling overload control than the previous generation. The most important innovation the solution is the multi-service engine, the world’s first innovation engine for web and video acceleration optimisation which is integrated directly into the PS core for greater flexibility of deployment.
The solution also provides an LTE voice solution that is set to be commercialized this year, the company reported. Huawei’s LTE voice solution provides a superior voice experience with low setup latency, clear HD voice quality, and highly reliable voice connections.
Single Radio Controller (SRC) solution
The single radio controller (SRC) solution is designed to achieve multi-RAT network synergy, enhance network capacity and efficiency and help operators build networks that provide a better mobile broadband (MBB) experience.
Operators are looking to introduce new technologies, standards and spectrum bands to solve capacity problems, and are now want to achieve multi-band, multi-RAT synergy and scheduling. Such an approach enables the efficient use of existing spectrum and site resources to maximize network capacity and provide the best MBB user experience.
Huawei's SRC solution realizes the centralized coordination of network resources for total multi-band, multi-RAT synergy. SRC includes Huawei's high-capacity, multi-RAT controller platform unifies network access control and coordination scheduling for GSM, UMTS, LTE FDD, LTE TDD and Wi-Fi networks.
SRC currently supports a maximum data traffic capacity of 120Gb/s, which is three times the industry average, and supports evolution to TeraSite levels of data traffic when effective smart device penetration reaches 100%. Its signaling processing capacity supports 64 million busy hour call attempts (BHCA), more than five times the industry average, and is the industry's most integrated network controller.
SRC employs a wide-range of innovative technologies for total synergy of multi-band, multi-cell and multi-layer networks. This enhances overall network efficiency by a leading 40%. At the same time, SRC enables centralized LTE network cell management, significantly reducing interference and enhancing cell-edge user throughput by 200% via scheduling of resources between cells.
LTE-B Vision FusionNet for future mobile broadband development
FusionNet represents a new generation of network architecture for LTE-B, according to Huawei. The new architecture improves cell edge user (CEU) throughput by at least 500% with a series of multi-RAT, multi-band and multi-layer HetNet enhancements to realize No-Edge networks of seamless high-speed coverage.
Huawei’s FusionNet concept for LTE-B comprises several core technologies, including multi-stream aggregation, interference coordination, traffic adaption and spectrum efficiency optimization. FusionNet coordinates existing LTE and LTE-A deployments and technologies (including CoMP and carrier aggregation) and delivers a fusion of multi-RAT, multi-band and multi-layer networks. A core benefit of FusionNet is its ability to drastically reduce network CAPEX and OPEX.
The FusionNet vision allows users to enjoy high speeds anywhere, anytime via access to reliable mobile broadband services. It delivers ultra-wideband, zero waiting and ubiquitous connectivity network capabilities to bring end-users high-speed and high-quality connections for a seamless, simple and service-enhanced mobile broadband experience.
Ultra Node prototype
Also at MWC 2013, Huawei unveiled its Ultra Node prototype design for future mobile broadband base stations. Ultra Node enhances the spectrum utilization and overall network efficiency to achieve a 50Gbps peak data speed in a single node.
Its core technologies (in addition to a redesigned antenna structure) greatly improves antenna performance, satisfies wideband and high network performance capacity demands, reduces networks costs and power loss, realizes multi-stream aggregation of ultra-widebands, and allows for greater channel capacity given implementation of a more advanced multi-antenna encoding algorithm.
