Faculty of Engineering and the Built Environment / Emergency services are vital for the minimization of damage, injury and loss of life.
These services are, by definition, a combination of telecommunications and information
services, and are by nature, distributed. However, most current emergency
services do not take advantage of emerging technology, and hence, are restricted in
the functionality they offer.
This project proposes the design a full information structure for an emergency call
centre service, which can be offered as a service or application on any core network.
As emergency services are distributed, and combine both telecommunications and
information services, an appropriate design tool which caters for these issues, is the
Reference Model for Open Distributed Processing (RM-ODP), which will be used in
the design of the emergency service. In addition, OSA/Parlay Application Programming
Interfaces (APIs) will be used for the application to access telecommunication
network functionality.
The enterprise viewpoint examines the design requirements and considerations for
an emergency system, which is the first step in designing a service based on the RMODP
guidelines. Secondly, the information viewpoint is defined, which identifies the
information flows between the objects and classes defined in the enterprise viewpoint
with the aid of robustness diagrams and high level message sequence charts. Next,
the computational viewpoint of the emergency service describes the components
that the service consists of and the interfaces through which they communicate,
enabling distribution of the system to be visualized. In addition, the engineering
and technology viewpoints are briefly touched upon.
The RM-ODP proves to be a useful tool the design of this application. In addition,
the use of OSA/Parlay APIs have also proved beneficial, enabling the application
to run on any platform, irrespective of the level of functionality it already provides.
The benefits that this design offers over conventional emergency services are allowing
callers and emergency response personnel full access to the functionality of the service, despite any limitations on their telecommunications network, finding the location
of a caller from a fixed or mobile phone, ease and speed of obtaining relevant
emergency information, and the ease and speed of sending relevant information to
emergency response personnel.
Finally we recommend improvements in the reliability and accuracy of finding the
location of mobile phones, as well as creating ways of identifying the location of
VoIP users.
