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)
This paper proposed an agent communication model including communication language specification based on OWL-communication language and communication actions, as well as formal communication process. So in the process of the interaction of multi-agent, agent must take the same communication language and use common understanding about the content of(More)
In order to provide end-to-end QoS in B3G systems, based on the UMTS architecture, the DiffServ framework can be used in the data plane of the IP core network of the mobile access network. Among the different schemes proposed for the control plane of DiffServ, the Internet2 bandwidth broker approach has been chosen for its centralized management nature,(More)
We propose an efficient uplink MAC protocol for a variable spreading gain interference-limited W-CDMA system. It can, with high spectral efficiency, support both real-time traffic like speech and video and also non-real-time data traffic based on packet transmission. The schemes for power allocation, scheduling, and transmission rate adaptation for non-real(More)
In this paper, a link adaptation scheme is proposed that integrates QoS information from the IP layer of the Differentiated Service Architecture (DiffServ) with lower layer criteria in order to improve Assured Forwarding (AF) traffic performance in a wireless CDMA system. The schemes for scheduling and rate adaptation are designed as integrated parts of the(More)
Knowledge representation and reasoning model play an important role in multi-expert system. In this paper, a new knowledge representation method, factor neural network theory(FNN), is used in multi-expert system for oil-gas reservoir protection. Firstly, by introducing factor and factor space theory, knowledge representation model based on factor state(More)
