Abstract
This paper defines the requirements for cooperation of heterogeneous radio
access networks (RANs) and proposes a novel radio resource management (RRM) framework for support of mobility and quality of service (QoS) in a heterogeneous communication environment comprising IMT-Advanced and legacy systems.The RRM mechanisms are evaluated for the scenario of intra-RAN and inter-RAN user mobility. The RRM framework incorporates as novelty improved triggering mechanisms, a network-controlledmobility management scheme with policy enforcement on different levels in the RANarchitecture, and a distributed handover and admission control mechanism for fast decision polling at different levels of the RAN.
