Περίληψη:
The introduction of ATM in Wireless CPN environments (WA TM)
necessitates the design of mobility related protocols, since the
existing versions of B-ISDN signalling (ITU-T Q.2931, ATMF UNI 3. 1) do
not provide the means for terminal mobility. Such protocols can be
deployed either as extensions to the standard signalling capabilities or
as individual solutions that have little or no impact on existing
infrastructures (switches, signalling software, etc.). In this paper,
after presenting a WATM architecture, we study the problem of the
switching/rerouting of the signalling connections that needs to be
performed whenever a mobile terminal crosses cell boundaries (handover,
location update). Registration and forward hard handover algorithms are
proposed.
