Overview of Emergency Communication Practices, Methods and Expected Outcomes
ICTs enable the linking of physical world within which hazards occur and symbolic world of the human likely to be harmed by those hazards, so that they may take life saving action. But the effective linking of these worlds requires not only ICTs, but also the existence of institutions that allow for the effective mobilization of their potential
(Samarjiva: mobilizing ICTs for disaster warning, 2005)
Physical world wherehazards occur
Symbolic worldwhere action
originates
TV, Radio & Cell broadcasts

Warnings (telecom)
Warnings (telecom)
The physical, the symbolic & their linking through ICTs, simplified More time to run; more lives saved

Alert Area Templates for Targeted Warning
1. Identify Risk (e.g Landslide)
2.Define targeted Alert area as a GIS Polygon
3. Assess whether the technology (e.g. cell towers) would cover the targeted area
Make the data available to the community and let them develop their own resilience plans
Telecom CDR (Big Data) Migration Patterns
Example of Open Signal data for TL
Components for Em. Comm. & Resilience
1. Critical infrastructure risk assessment
2. Alerting/Warning for situational-awareness
3. Situational Reporting for Emergency
Coordination
4. Telecommunications resilience and
availability
Situational Reporting
1.Victim calls or other calls
a hot-line
2.Filed observation (or
casualty-illness report
recorded
3.Situational-information is
processed
4.Response resources are
determined and deployed
Situational-Reporting (EDXL-SITREP)
1) SitRep: root element with qualifying elements
2) iReport: the type of report
• Field Observation: report sent by CERT members identifying incidents
• Situation Information: additional information for comprehensive information
• Response Resources: derived resources to deploy
• Casualty/Illness Summary: injury and health related information
• Management Summary: periodic summary of overall picture
Participatory approach to evaluating telecoms and vulnerabilityes
Resilience of ICT infrastructure
Infrastructure Vulnerable to------------------ ------------------Submarine cables EarthquakesFibre optics Earthquakes, infrastructureMicrowave Cyclones, Wildfire, powerHF/VHF Sever weatherSatellite Solar flairs, space debris
ICT infrastructure ecosystem - is located in physical space- it is powered by energy sources- it is operated by people
Backhaul networks[issue] :: wired & wireless public networks depend on domestic and international backhaul networks for effective functioning[remedy] :: Competitive market approach to redundancy and business continuity (i.e. liberalized environments, multiple suppliers and technologies)
Congestion[issue] :: consequences of congestion for first responders are extremely serious. [remedy] :: is subscriptions to TETRA networks which are not interconnected to public networks
Optimizing the use of available networks
1) Understand the Coverings
2) Limit to the perfect Matchings
3) Optimize the objective subject to constraints (LP problem)
