Information Technology Reference
In-Depth Information
information collection terminals (i.e., sensors) must be con-
figured for each individual. A BSN is used to realize the
multimode acquisition, integration, encryption, and real-time
transmission of personal health information in living, working,
or hospital environment. As shown in Figure 6.1, various
communication and computer networking technologies can
be used. They include Bluetooth, WiFi, and GSM/GPRS/3G/4G
digital cellular networks. GSM stands for Global System for
Mobile Communications, which is a technology for the second-
generation (2G) digital cellular networks. GPRS represents
General Packet Radio Services, which is expanded from
GSM and is often referred to as the 2.5G technology.

Cloud platform
. Based on the cloud computing technology,
one can achieve the rapid storage, management, retrieval, and
analysis of massive health data mainly including electronic
medical record (EMR) repository, scientific knowledge
base of health care, and personal health data acquired
from BSN.
3.
Health care service system
. It includes a personal health
information management system, a dynamic personal health
monitoring system, a real-time early-warning system, a per-
sonal health risk assessment and guidance system, a seasonal
disease early-warning system, a decision-making library for
various diseases, and many typical disease care services. Some
of the services will be in detail described in Section 6.2.2.
Next, we discuss the following design and implementation tech-
nologies used to realize PHISP:
1. SOA and Web service technology;
2. Activity diagrams for specifying composite services; and
3. Service composition methods with choice and parallel
structures.
6.2.2 Services Encapsulated in PHISP
PHISP utilizes the design idea of SOA and Web service technology for
its design and implementation. The majority of its functional modules
