Huawei has today launched the 'world's first' convergent Base Station Controller (BSC) which integrates both the GSM BSC and the UMTS RNC (Radio Network Controller) into one multi-mode controller.
The new equipment, combined with the other features of the SingleRAN solution, is claimed to enable operators to achieve the full convergence of multi-mode wireless networks, including greater efficiencies with operation and maintenance, radio resource management and transmission resource management. Specifically designed to support multiple wireless systems via a single uniform access network, the SingleRAN solution integrates radio bearers for voice, narrowband data, mobile broadband and more into one network element instead of many, says the company.
"Convergence and scalability have become ubiquitous links in our value chain and the launch of the world-first multi-mode BSC is another key step towards a fully converged network evolution for operators," said Mr. Wan Biao, president of Huawei wireless product line. "With one purchase decision, operators can now realize the optimal benefits of ownership from a cost and time efficient solution for multiple network investment protection, enhanced performance, reduced OPEX and CAPEX, and improved TCO."
Huawei has also launched two software defined radio (SDR)-enabled RRUs (radio remote units) with dual-transmitter capability – an industry first. The first RRU supports GSM/UMTS/LTE technologies by using the same 1800M/1900M/850M/900M spectrum and is the only SDR-enabled RRU product to have received standardization by the European Telecommunications Standards Institute. The second SDR-enabled RRU can provide UMTS/LTE services while using the same 2100 MHz spectrum.
Huawei's SingleRAN solution enables operators to achieve full convergence of multi-mode wireless networks, including base stations, base station controllers, sites and operation as well as maintenance management. It provides a unified radio access network which can achieve GSM, UMTS and LTE functionalities simultaneously and is software configurable according to different traffic models to have more GSM or UMTS capacity.
