Project Summary
Comprehensive Emergency System(CES) is a comprehensive
platform to link hospitals, ambulances and operator by
transferring patient data and electronic health record in
addition to location by GPS.
we need to use SOA approach to integrate all applications
based on web services and Mobile web services.
At the end of this project, we are supposed to have SOA
platform for CES.

Research Objectives
The main objectives of this research are :
Define architecture for Comprehensive Emergency System(CES) .
Identify services using Service Oriented Architecture (SOA) approach.
Services Modeling by using Service Oriented Architecture Modeling
language (SoaML) technique.

Introduction
Service oriented architecture.
Web services technology.
Mobile web services.

Problem Statement
Transport and ambulance patients after the accident became
the most important problems facing society.
The statistics (2008-2009) from site traffic Riyadh.

contributions
Development SOA platform for a Comprehensive Emergency
System(CES) .

Related Work
Some systems used radio communicate.
Some new systems include a computer system as tool to help
in the management of communications such as the Computer
Aided Dispatch(CAD).
Some systems based on wireless data communication
between ambulances and hospitals.
A new concepts SOA, WS, and Mobile web services.

Assumptions
During the analysis and construction of the project, there is a
set of assumptions:
Most modern mobile devices capable of specific GPS.
There are private ways for ambulances.
The roads are numbered and well-known GPS system.
There is a center of health records of all hospitals.

Comprehensive Emergency System Architecture

Hospital System processes (Pseudo Code)
Input:
 Patient case, // send by HS
 Patient health record // The HS request HR by using patient national ID
Output:
 Specific availability of beds and the availability the section,
 Specific availability of doctors,
 Send confirm message take/reject case,
 Specific consultants information and call them
BEGIN
Receive patient case ; // from HS
If hospital beds ='available' than {
If hospitals doctors ='available' than {
Send confirm message take case();
Track the ambulance by using GPS Map();
Supply the rooms and staffs();
Else
call the doctors and consultants();
End if; }
Else
Send confirm message reject case();
End if; }

Challenges
There are many challenges during the project work:
Lack of distinctive free programs that use for SOA modeling.
The absence of clear guidance to extract services.
The design of services needs from you a long experience in using the
right tool.
Collect appropriate information about the project, that project is too
large and comprehensive.
Project need for visits to hospitals, to verify the method of work and
analysis the work.

Conclusions and further work
In this research, a new framework that handles an
unexpected emergency accident has been proposed. The CES
subsystems and their roles have been identified and build
Service Modeling. The integrated work flow between the CES
subsystems and the way to share data has been presented.
As for a future work, we plan to use the quality of services
(QoS) to test the performance of all subsystems with the CES
framework. Also, we plan to apply HL7 between subsystems
in CES. Moreover, we plan to use scripting to model the rules
within these engines
