Disaster countermeasures for NTT involved in many activities and studies relating to disaster mitigation DOCOMO’s network and relief operations, such as the ITU workshop on “Disaster relief systems, network resilience and recovery”. In the field of To ensure the availability of telecommunication services radiocommunication, ITU-R (the ITU Radiocommunication in the event of a disaster, we aim to build a disaster resilient Sector) recently enhanced its relevant Recommendation1 taking telecommunication network by improving the reliability of our into account the scope of two Resolutions 2, 3 so as to include a new infrastructure systems (with particular regard to emergency application of disaster relief operations, which has been used in communications) so that our telecommunication services can be NTT DOCOMO’s network. recovered quickly. Japan is known to be prone to large earthquakes such as the To achieve better reliability, we have installed backup Great East Japan Earthquake of March 11, 2011, which also equipment and links, and we have reinforced our facilities, caused a huge tsunami. This devastating natural disaster destroyed buildings and towers to make them more earthquake resistant. For or damaged much of the telecommunication infrastructure in the emergency communications, we have adopted a call priority service affected area, rendering it unusable. that can be used in disaster situations to safeguard communications For the quick and efficient recovery of cellular phone services to and from regional municipal offices, and network control in disaster-hit areas, DOCOMO has developed and introduced a procedures that enable networks to cope effectively with emergency number of vehicle-mounted mobile base stations, which operate in traffic. ■ Figure 1: Conceptual diagram of the vehicle-mounted disaster relief operation system 2 New Breeze Summer 2014 ■ Photo 1: DOCOMO’s vehicle-mounted transportable system ■ Table 1: Main specifications of transportable FWS for disaster relief operation Frequency Transmission Capacity Interface Antenna type band distance * Upper 4 GHz band 7-35 Mbit/s 100BASE-TX 36 cm flat panel around 10 km (4.92-5.0 GHz) ** 18 GHz band 0.4-1.2 m (17.85-17.97 / 155.52 Mbit/s STM-1 around 3.5 km diameter dish 18.6 18.72 GHz) : The RF channel is selected within the assigned frequency band. * : Connected to the MPX (multiplexer) via Ether/ATM converter. ** ■ Table 2: Example parameters of transportable mobile base station Bandwidth Frequency band Antenna type (Carrier number) Corner reflector 800 MHz (830-845/875-890 MHz) 15 MHz (3 carriers) * (40 cm × 37 cm) Corner reflector 2 GHz (1 940-1 960/2 130-2 150 MHz) 20 MHz (4 carriers) (23 cm × 42 cm) * ** : 5 MHz bandwidth per carrier. * : Maximum aperture. ** For the quick recovery of telecommunication services, we to install on vehicles.
