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
Philippe COUDE
Yijun WU
Marie - Michéle VASSILIOU
Avinash JOSHI

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.

For more details, see our Terms of Reference

How we do it:

The aim of this work will be:

1.     to collect and analyse existing studies on statistical handling of QoS results in three exploratory domains (Figure 1 – area 1, 2 and 3);

2.     to propose the method supporting the E2E QoS Signalling, SLA commitments and Inter-working QoS (Figure1 – area 4, 5 and 6);

3.     to specify the QoS continuity in order to achieve the goal of the new scope.

The study areas are shown in the following figure :

In a first step the study will focus on 3 subfields:

  1. 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, security etc. 
  2.  Mobility, which refers to two types as terminal mobility and user mobility. 
  3.  Heterogeneity, which represents the nowadays heterogeneity of the networks, as well as the heterogeneity of the services that caused heterogeneous QoS mechanisms.
  4. User continuous services with a proper E2E QoS signalling considering mobility. 
  5. The user connectivity to a heterogeneous network respects always the <st1:place w:st="on">SLA including user preferences. 
  6. An inter-working QoS to enable terminal mobility crossing heterogeneous network. 
  7. 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:
