Opportunity
Emerging standards for mobile ATM ("M" ATM) networks
add network level support for terminal mobility to existing
ATM networks. These mobility enhanced ATM networks use the
ATM switching and control infrastructure to provide seamless
wired and wireless networking. "M" ATM networks
support new ATM wireless access technologies for end-to-end
wireless ATM ("W" ATM) networks, as well as existing
non-ATM wireless access technologies for backward compatibility
with existing wireless networks.
Aricent having studied the requirements of extending
the ATM network to support ATM by adding support for Location
Management and Handoff was involved in the architectural design
and specification for the support of non-ATM wireless access
technologies over an M-ATM and is demonstrating the design
through a prototype development of the Mobile ATM-GSM Base
Station. The concept of mobile ATM has been proven through
its capability to support both ATM and non-ATM wireless access
technologies.
Aricent Solution
Aricent was involved in defining the specifications for interworking
between Mobile ATM and GSM Protocol mapping between Mobile
ATM and GSM; Designing and architecting the Mobile ATM-GSM
base station. This would enable the wireless ATM to extended
in such a manner that a GSM mobile will be able to make a
phone call to another GSM mobile using the mobile ATM network.
Aricent's role in the project was to develop the Inter-working
function (IWF).
Other software services rendered to the assignment included
the following:
- Basic call establishment/release services
between two GSM mobiles across the core wire-less ATM network
- Support for call handoff from one IWF to
another IWF
- Roaming for the GSM mobile from PLMN to ATM
network
Aricent was further responsible for providing the
software for the IWF. The work involved development of BSSMAP
and DTAP protocols including Mobility Management and Call
Control protocols and also the SS7 APIs used to interface
with the E1 card. The protocol work was carried out in SDL
using Telelogic SDT tool. In order to carry out the development
at Aricent , a Siemens protocol analyser was used to
simulate the BSS and the mobile for testing.
