Abstract.

The different mobile wireless communication systems that are currently
available adopt common solutions for dealing with recurring mobility
management problems associated with similar architectural elements. This
work extracts and documents patterns that identify such common problems
and solutions among second generation systems, for example, GSM-900 and
D-AMPS. These patterns are grouped into a pattern language that shows how
they interact. At a high level of abstraction, the pattern language makes
it possible to generate different scenarios of the mobile system behavior.
