The application
where user sends SMS to retrieve information on
demand is defined as Mobile Originated or Pull
Application. The message can retrieve by
CellApps
from the mobile device and based on the SMS content
it retrieves the information. The CellApps application
interface layer provides different mechanisms
to define the message handling. These include:

the message, it checks which script or handler
to be called based on the keyword in SMS message
and sends the reply by either picking up information
from database, website a file or generated by
some other application. |
