6 Overview of the multi-connection architecture

6.1 General architecture
The multi-connection architecture (MC-ARCH) enhances the NGN to support the ability of multiple
concurrent sessions from a single UE in a coordinated manner. In order to achieve this, NGNs and UEs require
the addition of new functions.
The general architecture for multi-connection includes the following major functions, as shown in Figure 6-1:
1) Deployment of the multi-connection access technology policy and maintain information (such as
traffic, usage duration, bandwidth, connection status, etc.) of the available connections for MUEs;
2) Manage connections to initiation, transfer, release and update;
3) Provide mobility related services;

4) Provide flow-based management related services;
5) Provide session continuity for applications/services;
6) Provide QoS and relevant policy control;
7) Manage multi-connection applications with proper access information statically or dynamically;
8) Support authentication, authorization and accounting (AAA) functions for multi-connection services
and assist AAA related events in each access technology;
9) Support mechanisms for service composition and decomposition which allow separation of one
session of the relevant service (e.g., audio/video service) into several flows and vice versa;
