Specialist Task Force
360: QoS management at the Network Interfaces (juxtaposition)
to optimize quality of the service delivered to the User
Who we are:
Team Leader: Pierre - Yves HEBERT
Team Members: Tatiana KOVACIKOVA
Marie - Michéle VASSILIOU
Why we do it:
Providers seem to agree that most QoS deteriorations are occurring at the
network borders due to insufficient standardization of the interfaces.
Therefore, the User Group believes that a review of the available
standardization at these interfaces should be carried out to identify the lacks
with regard to the QoS and make proposals to improve the situation, using the
opportunity of the near outcome of the NGN.

How we do it:
The aim of this work will be:
to collect and
analyse existing studies on statistical handling of QoS results in three
exploratory domains (Figure 1 – area 1, 2 and 3);
to propose the
method supporting the E2E QoS Signalling, SLA commitments and Inter-working QoS
(Figure1 – area 4, 5 and 6);
to specify the
QoS continuity in order to achieve the goal of the new scope.
The study areas are shown in the following figure :

From existences to concerned problem
In a first step the study will focus on 3 subfields:
User requirements and preferences, the former abstracts all user demands in
form of user continuous multimedia services requirements. The latter
represents all his personal information in the aspects of utilization, QoS,
- Mobility, which refers to two types as terminal mobility and user mobility.
- Heterogeneity, which represents the nowadays heterogeneity of the networks,
as well as the heterogeneity of the services that caused heterogeneous QoS
- User continuous services with a proper E2E QoS signalling considering
- The user connectivity to a heterogeneous network respects always the <st1:place w:st="on">SLA including user preferences.
- An inter-working QoS to enable terminal mobility crossing heterogeneous
- Based on the user centric requirements, according to a Top-Down analysis, we
propose to highlight the QoS continuity considering nomad user crossing
heterogeneity to realize service continuity.
Time plan for the work:
The work is split in several package as shown below:
|Planning and project organization
||Control plan solution: QoS signalling
|Deliverable (Part 1)
||Management plan solution: QoS Inter-work
|Deliverable (Part 2)
||Converging solution: QoS continuity
|Deliverable (Part 3)
||QoS informational structure
|Deliverable (Part 4)
