Common Radio Resource Management strategies are devoted to achieve an efficient usage of the pool of radio resources available in a heterogeneous radio access network context. This paper describes the functionalities associated with the common vision of radio access technologies, the different possibilities in the functional model split and the(More)
This paper proposes a new Common Radio Resource Management (CRRM) methodology which allows increasing the capacity of heterogeneous CDMA/TDMA. This is achieved by controlling the effective cell radius of the CDMA-based system (i.e. a network-controlled cell-breathing) through appropriate initial RAT selection and vertical handover strategies, so that the(More)
With IP technology being in the epicenter of future wireless networks, IP-centric resource management is currently receiving an increasing research attention. In this paper, a power and rate adaptation semantic is proposed that integrates quality of service (QoS) information from the IP layer of the differentiated services (DiffServ) architecture together(More)
— In the B3G system considered, which is based on the 3GPP UMTS architecture, the initial hypothesis made in this paper, is that the QoS management of the IP access network is taken in charge by a bandwidth broker. A pre-handover signalling for QoS-aware path selection is investigated with the goal of achieving the " Always Best Connected " paradigm.(More)
A link adaptation schemes is proposed to improve the efficiency to support DiffServ traffic over CDMA air interface. To differentiate the resource allocation between DiffServ PHBs and between the in/out profile packets within each AF class, two-level differentiation is done in the proposed scheme: inter-class differentiation and intra-class differentiation.(More)
