Question 9/13 – MM mechanisms supporting multi-connections for multiple access technologies
(New Question)

Motivation

The motivation for this new question, or more precisely a broadening of studies carried out in previous questions posed in SG 19’s period 2005-2008, focuses on the support of multiple connection points related to multiple RATs and fixed accesses.

The work in SG 19 in the 2005-2008 study period was done with awareness of evolving mobile and fixed network access technologies at the transport level.

Different access technologies have different advantages. The main purpose of multiple connection is to federate all means of access technologies in order to access the network ubiquitously (from everywhere and at any time). Introducing multiple connection technology will help us to provide better user experience.

Multiple connection harmonization can bring benefits for operators, such as efficient utilization of network resources, load balancing, reliability of connection and continuity of services, etc.

This contribution proposes a new question to study the multiple connection harmonization for multiple access technologies.

Question

Study items to be considered include, but are not limited to:

  • What architecture and mobility management mechanisms should be supported and new functional requirements developed to support the harmonization of multiple connections for multiple access technologies
  • What enhancements to existing Recommendations are required to provide energy savings directly or indirectly in Information and Communication Technologies (ICTs) or in other industries? What enhancements to developing or new Recommendations are required to provide such energy savings?

Tasks

Tasks include, but are not limited to:

  • Explore the scenarios and the policies for multiple connection harmonization in mobile networks utilizing fixed and mobile accesses
  • Develop proposals based on the study of multiple connection and their harmonization in mobile networks utilizing fixed and mobile accesses and their components in the context of the questions above
  • Identify which MM mechanisms are required to provide service continuity through multi connection in multiple access networks and at the same time their effect to provide unawareness of such functions to multimedia services.
  • Determine scenarios for service continuity to support multimedia services, especially for real- time services such as VoIP, video streaming, real time text and Video on Demand.
  • Determine inter layer information needed to be delivered to meet the requirements of multiple connection harmonization to support its services in the realm of heterogeneous accesses.
  • Identify which QoS mapping mechanisms among RATs need to be executed in multiple connection harmonization to provide networks with acceptable levels of quality of perception.
  • Although, it is foreseen that a new Recommendation may be required, the outputs produced under this question will generally progress through, or in coordination with, other related questions.
