Project
Objectives and Expected Results
The SAILOR project will implement a
demonstrator, aiming at a complete integration between T-UMTS & S-UMTS. The
demonstrator will add new functionalities that will exploit more efficiently
the utilization of the satellite segment, provide a meaningful environment
suitable to implement advanced
multimedia services(broadcast, multicast)and allow a more advanced
implementation of the UMTS Core Network. The demonstrator will consist of a
real UMTS Core Network, to be developed through a completely innovative approach
and of 2 Access Networks, to be designed through a specific software emulator
environment allowing to test the presence of a real cellular layout with
multiple cells and terminals. The demonstrator will be used to carry out 2
experiments, Fully IP Based Core Network Experiment and Access Network
Resources (satellite-terrestrial) Optimisation Experiment.
Furthermore, it targets at
contributing to the activities of the relevant UMTS ETSI and even 3GPP
standardization groups, which are
involved in the development of new market scenarios for the 3G satellite
systems and in the adoption of innovative network tools targeted to support
these proposed scenarios.
The SAILOR project will also base its activities on the work which is being carried out in other IST projects (in particular, VIRTUOUS and FUTURE, but even ARROWS, GAUSS, BRAHMS, SUITED, GEOCAST, WINE GLASS, etc.)
In conclusion, SAILOR’s final
objectives are the guidance of the Advanced Satellite Mobile Systems S-UMTS
task force, aiming at the standardization of the designed and experimented
innovative functionalities, as well as the development of advanced multimedia
services, upon the integrated T-S-UMTS, which can be commercially exploited in
a short term.
Ongoing Technical
Activities
The work undertaken in the SAILOR project is
divided into the following eight Workpackages:
WP 100 Management
WP 200 Market Analysis
WP 300 Requirements and System Architecture
WP 400 Fully IP Core Network experiment
WP 500 AN Resources Optimization experiment
WP 600 Integration and Test plan
WP 700 Trials
WP 800 Dissemination, standardization, exploitation
WP100
Ø
Editing
of the Management Report for the reference period November-December 2004.
Ø
General
project co-ordination activity with tracking and closing the action items
pending after PM 9th .
Ø
Review
of PRR-2 according to the EC’s comments and delivery to the Commission of the
updated issue.
WP200
Ø
The
activities realised in this period for WP200 were focused on the approach to be
implemented for the update of the market analysis carried out in WP 200 on the
basis of the last presentation of the Deliverable D02.02 Addendum released in
March 2004. More operationally the work will lead to the identification of the
technological and market issues for which new information will be researched
and elaborated in the frame of the overall WP 200 methodology. The preliminary results will be
presented at the project progress meeting scheduled for 14 March 2005.
WP300
Ø
Activity
related to the trial campaign was tracked and monitored in order to check
coherence with the SAILOR DEMONSTRATOR architecture to be finalised with the
D03.03.
WP400
Ø
In
order to obtain comparable analyses an adaptation was made of the SAILOR SIPran
message used in WP 400 to the ANPS (Access Network Protocol Simulator) tool.
Now a comparative analysis of the session set up procedure between the
conventional, i.e. NAS and SIP, and SIPran control signalling is possible.
WP500
Ø
The
overall objectives of the work package was positively achieved. WP500 terminated, therefore no
activity was carried out in the referenced period
WP600
Ø
Coordination
of full integration tests on the complete test-bed and fine tuning and bugs
fixing of demonstrator during trials execution
·
Minor
Updates to RASN software during the trials’ preparation phase. The updates were
related to SIP message timeouts handling.
·
Finalised
contributions on D06.02 concerned with:
o
The
cases relevant with the integration of the SAILOR demonstrator building blocks.
o
The
refinements of the PLSE SW module.
Ø
Finalisation
of activities regarding the integration between CPT and DANS in order to allow
a correct run of the various simulations.
Ø
Edition
of D06.02 deliverable
·
Contributions
to D06.02 deliverable on ANE and general demonstrator tests results.
·
Formal
delivery of addenda to D06.02 on DANS-CAC and CN-MAS test and user operational
manuals.
WP700
Ø
The
SAILOR DEMONSTRATOR Trial activity started at the end of December 2004
continued according to the schedule defined in the Deliverable D07.01
·
Simulations
for the comparative investigation between the conventional and SIPran control
signalling methods.
o
Modelling
of the Interferences from the results of the DANS simulation
o
Terrestrial
and satellite UMTS cases
o
ANPS
Simulation for session setup procedures
o
Results
have been delivered to SAGO (WP 400 leader) on 24. Feb. 2005
·
Trials
executed on the SAILOR EMULATOR installed at the ISM premises in Seville by TPZ
with local support by ISM and remote support by SAGO for SIP configuration set-up and operation. The remote
assistance has been given by phone and email especially concerning:
o
appropriate
configuration settings of the SAILOR SIP client
o
capabilities
of the SIP client with respect to supported video formats and their bandwidth
o
handling
and appropriate usage of the SIP client for executing trial cases.
·
Trials
on ANPS-MAS were jointly carried out by UNIVAQ and AU, This effort produces a
first draft for the D07.02 contribution: in particular a set of graphics have
been reported. Moreover a slight adaptation of MAS code has been required in
order to make this module more standard compliant
·
The
CPT trial has been carried out by UOR in the framework of the SAILOR SIMULATOR
subsystem. The main result for this trial is to produce an optimised cellular
layout in a single and in a multi-service environment. The expected results has
been obtained, either for the “single service” environment and for the “multi
service” one.
Ø
Trials
on DANS-CAC were executed by TPZ according to the plan. All trial planned
scenarios were run and output
plots were generated for analysis. An additional extended scenario was also
defined for summary reporting on trials. Analyses of results started on
completion of simulation runs and are in progress.
Ø
The
trials on CN-MAS will start in March for completion by the end of that month.
Ø
Preparation
of reports on trials is progressing and delivery of D07.02 is planned for the
end of April 2005.

UMTS Sailor recibe la luz verde de la UE”, focussed on the SAILOR project.
Web site
Ø
A Web
site on the SAILOR project is hosted and maintained at the Telespazio Service
Centre. Following the Service Centre expansion and web site re-organisation,
the SAILOR web site moved to the new URL http://www.newapplication.it/sailor/,
which replaces the former one (i.e. http://galileo.cs.telespazio.it/sailor/,
that however will be temporarily maintained).
Ø
The
newsletter section of site was updated.
