Nokia Siemens Networks (NSN) has announced that it has expanded and upgraded the packet core network of Vietnamese telecoms operator MobiFone, boosting capacity of the network by around 50%. Under a separate contract, the Finnish vendor has also modernised MobiFone’s GSM and 3G radio network with its Single RAN platform in southern and central Vietnam. This will enable the operator to better handle the surging demand in data on its networks from a rising number of mobile broadband subscribers. Both the upgraded packet core and radio networks are already in commercial use. ‘We needed a reliable and flexible network that is able to accommodate the data traffic demands of today and tomorrow. In addition, we wanted to modernise our radio network to improve traffic capacity for our existing GSM network and enhance service experience for our GSM and 3G subscribers,’ said Nguyen Dang Nguyen, deputy general director at MobiFone, adding: ‘NSN has helped us realise these twin goals. The high capacity core network will help us serve more subscribers, while the modernised radio network will enable us to offer high speed data services to our growing number of smartphone subscribers.’ Under both the contracts, NSN provided services that include network design, installation, commissioning and implementation besides end-to-end project management for rapid rollout of the network.
