Development of New compact Core Network System for LTE Wireless Network by NEC
For what has been anticipated to be the next generation of wireless technology LTE is certainly gaining momentum both in terms of popularity among the service providers as well as Telecomm network equipment manufacturers around the globe. Offering a higher transmission bandwidth of around 100mbps in comparison to current wireless technology such as WiMax and such and ease of deployment through upgrading the existing wireless infrastructure is proven to be the only viable alternative for service providers in terms of ROI. In light of this network equipment manufacturers are gearing up their product development roadmap to accommodate the service provider’s ambitious time table of LTE deployment. One such company is NEC who made an announcement on development of world’s smallest EPC system for LTE network. The new EPS system combines the MME (Mobility Management Entity) for managing the location and paging process of LTE systems, Serving-GW for processing users’ voice and data packets for 2G/3G and LTE systems, PDN-GW for managing interface between EPC and external networks (Internet and IMS etc.). Each compact LTE system is capable of simultaneously serving around 300,000 subscribers while controlling more than 1,000 LTE base stations. All the functions are loaded into compact blade integrated advancedTCA® chassis which is industry standard for next generation carrier grade telecommunications equipment. EPS is part of the core network system controlling the LTE base stations, where both EPC and LTE are moving currently toward standardization by 3GPP, a standardization body for mobile communication systems. The NEC’s EPC are in compliance with 3GPP mobile communication standards. The new EPC system measuring 483mm (L) x222mm (H) x497mm (D) which can fit the 5U-heigh a standard 19-inch rack.

[...] NEC Corporation made an announcement on extending OpenFlow Technologies to Mobile Network as part of promoting globally open innovation for future Internet technologies. The new technologies incorporated modules capable of observing the utilization status of multiple base stations for each mobile communication method, dynamically selecting the most suitable mobile communication routes by analyzing location information within mobile networks, received signal power level, communication resource utilization and mobile backhaul congestion. In addition to these capabilities, the new technologies provide high quality services through dynamic switching between heterogeneous mobile communications methods and improved energy efficient method by switching off the low communication load base station for mobile backhaul networks, including base stations, network lines, switches and servers. Furthermore, the use of OpenFlow will provide an efficient and flexible network management of mobile networks, a must due to its ever growing speed and bandwidth. Through use of these new technologies mobile communications carriers would benefit in a great cost saving in operational management while creating new services. source Share and Enjoy: [...]
