Method for executing a communication attempt with a mobile terminal device
in accordance with an attainability status of a mobile terminal device in
a cellular communication network having a Short Message Service Center
by: querying the SMSC in the cellular network for obtaining the
attainability status of said mobile terminal device and delivering said
communication attempt to said mobile terminal device in accordance with
said attainability status. This invention allows an application to find
out if a mobile terminal device e.g. a handset is reacheable without
actually contacting the handset. A short message service center does this
by initiating a mobile terminated delivery attempt but not finishing it
but telling the application instead if the home location register of a
cellular network thinks the handset is reacheable or not.
