This paper first propose a general architecture of mobile social networks where individuals in the netwok form a virtual community,conversing and connecting with one another, based on mobile communication. Second, they describe an implementation of mobile social networks in collaboration with a supported employment program established for people with severe mental illness.
And they proposed system architecture is shown in Fig. 1. It consists of four main components: the client devices, the wireless access network, the Internet and its hosts, and the server side that accommodates the batabase and application-specific servers that are required in the system.
Use this architecture, they implement a system using PDAs with cellular phone data connections for user with mental illness who travel to and from work. The system includes a button that the user can press to ask for help if they got lost or encounter a problem during travel to or from the work place. The system is location-aware so it can put the user in contact with a caregiver or service provider that meets the specific needs of the user and who is infairly close proximity.
And the caregiver also can get the message if they don't finish the travel on time.
The use of both web-based interfaces and SMS messages on mobile phones is recognized as a benefit because many jop coaches work away from their offices.
