Interworking QOS Management Subsystem into IMS-Based Architecture Multi Providers: IMS-IQMSMP

International audienceThe third-generation partnership project 3GPP and 3GPP2 have standardized the IP multimedia subsystem (IMS) to provide ubiquitous and access network-independent IP-based services for next-generation networks via merging cellular networks and the Internet. The IP Multimedia Subsystem (IMS) seems to be the technology that will prevail in Next Generation Networks (NGNs). The users wish to communicate through collections of networks using different protocols; rendering service mapping from one network to another with the similar QoS is a complex issue thereby. The heterogeneous networks are collections of communication platforms using different protocols. This heterogeneity implies the need to offer many different services on the market within short time. In this paper we propose a heterogeneous network model based on the IMS that provides guaranteed QoS. Our method presents, in the first, an informational solution. Decisional information is added to the HSS basis to enrich the knowledge base, which is expressed under the form of "profile of QoS R", where the new information informs directly the decisions to be taken according to the user’s profile (preferences QoS and pricing, bandwidth, location ...). In the second, a solution for multi provider’s context which can allow a subscriber to register with one or more operator(s) according to QoS offered. Thirdly, a mechanism which can be deployed in heterogeneous networks to preserve the original QoS values of the user session and thus eliminate the cumulative effect of QoS rounding across the entire communication path. And it is feasible via the “Interworking QoS Management Sub-network” while adding the new interworking management components, namely: SICs, DIC, QPA AS and HSS-PQoSr

Differentiation of Fanconi anemia and aplastic anemia using mitomycin C test in Tunisia

International audienceFanconi anemia (FA) is a recessive chromosomal instability syndrome that is clinically characterized by multiple symptoms. Chromosome breakage hypersensitivity to alkylating agents is the gold standard test for FA diagnosis. In this study, we provide a detailed laboratory protocol for accurate assessment of FA diagnosis based on mitomycin C (MMC) test. Induced chromosomal breakage study was successful in 171 out of 205 aplastic anemia (AA) patients. According to the sensitivity of MMC at 50 ng/ml, 38 patients (22.22%) were diagnosed as affected and 132 patients (77.17%) as unaffected. Somatic mosaicism was suspected in an 11-year-old patient with a FA phenotype. Twenty-six siblings of FA patients were also evaluated and five of them (19.23%) were diagnosed as FA. From this study, a standard protocol for diagnosis of FA was developed. It is routinely used as a diagnostic test of FA in Tunisia
