PDA Adaptor
The PDA
adaptor sits between the mobile clients and the GMS system and does
user management, message mapping, connection management, and message
optimization based on the user and device specification. The PDA
adaptor looks like a typical Garnet client to GMS, and adapts data
to the mobile device client specifications. For instance, the PDA
adaptor listens to all the messages and events on the Garnet
collaboration system by subscribing to GMS and it delivers messages
from the mobile clients to GMS by publishing regular GMS message.
HHMS is
a natural modification of the event service of GMSME bearing in
mind the constraints of hand held devices. The PDA adaptor parses
the GMS XML message body and delivers it to the mobile client over
HHMS. HHMS protocol contains only the necessary data for message
delivery in optimized form.
