Abstract. As mobile access to information es mon trend
in mercial and corporate information systems, new software
engineering challenges arise. While the most visible problems in mobile
systems are munication infrastructure and technical constraints
of portable devices, there are also conceptual architecture issues that
must be properly addressed.
This paper describes our work in progress towards categorizing and ana-
lyzing conceptual architectures for mobile information systems. We have
defined the basics of a domain-specific architectural pattern catalog for
this domain, and mined several patterns from existing, well-known sys-
tems. Our approach does not concentrate on the technical issues, but
rather on identifying those architectures that better fit business goals
regarding mobility.
Our goals are twofold. First, we aim to build a catalog of architectural
solutions proven essful in industrial practice. On the other hand, we
want to define a high-level, common-language to describe mobile archi-
tectural solutions.
1 Introduction
As mobile access to information es mon trend in mercial
and corporate information systems, new software engineering challenges arise.
While the most visible problems in mobile systems are munication in-
frastructure and technical constraints of portable devices (. mobile phones
and PDAs), there are also architectural issues that must be properly addressed
at the conceptual level.
Current research in software artifacts regarding mobility concentrates pri-
marily on fine-grained technological issues, such as working [14] and
constrained hardware [13]. Unfortunately mobile information systems are sel-
dom stable (because of technological improvements or changes in the underlying
