  • Methods and system in supporting real time services with spectrum efficiency in a satellite network

    Approaches are provided for efficient bandwidth allocation for real-time service traffic flows, providing for assured QoS and efficient spectrum utilization. A terminal of a wireless communications network receives data from one or more associated interface devices. A snooper captures a session request message from one of the interface devices for initiation of a setup process to establish a communications session over the communications network, and parses the session request message to obtain associated session parameters. Inroute bandwidth requirements for the communications session are determined based on the session parameters. A bandwidth reservation process is initiated to obtain bandwidth allocations to satisfy the inroute bandwidth requirements. The session request message is held until completion of the bandwidth reservation process, whereupon the session request message is transmitted to a session controller at a core node of the network, and the setup process to establish the communications session is completed.

  • Bandwidth management across logical groupings of access points in a shared access broadband network

    Systems and methods provide bandwidth management on the inroute of a satellite network. Inroute group managers (IGMs) monitor bandwidth usage in each terminal group (TG) under each of the IGMs, and report this bandwidth usage to a bandwidth manager. Upon receipt of the reported bandwidth usage from each of the IGMs, the bandwidth manager compares the bandwidth usage and minimum/maximum throughput rates associated with each TG. The bandwidth manager calculates scaling factors that it transmits to each of the IGMs to allow the IGMs to allocate bandwidth accordingly.

  • Targeting of molecules to large vessel endothelium using EPCR

    Endothelial protein C receptor (EPCR) is found primarily on endothelial cells of large vessels. EPCR translocates from the plasma membrane surface to the nucleus. Molecules which bind to EPCR can be carried from the plasma membrane surface to the nucleus. These molecules include antibodies to EPCR and activated protein C. Protein C, which also binds to EPCR, can be internalized by endothelial cells, but does not enter the nucleus. Thus, EPCR translocation from the plasma membrane to the nucleus provides a means of delivering nucleic acid such as DNA, proteins such as transcription factors, diagnostic agents or other types of drugs to the nucleus of endothelial cells, particularly those on large blood vessels. Conjugates of the materials to be delivered to the nucleus can be formed by ionic or covalent coupling. For example, proteins, including fusion proteins, can be directly conjugated to an anti-EPCR monoclonal antibody. Covalent attachment of positively charged polymers, such as polylysine, to an anti-EPCR antibody allows nucleic acid to bind by ionic charges. Steptavidin and biotin can also be used to conjugate molecules to anti-EPCR antibodies. These conjugated antibodies are transported to the nucleus by EPCR. Eamples demonstrate selective transport to the nucleus which is mediated by EPCR. Molecules transported include activated protein C, antibodies to EPCR, and steptavidin-biotin conjugates. Modification of anti-EPCR monoclonal antibodies by covalently coupling to polylysine allows binding of an expression vector to the modified antibody and translocation to the nucleus.

  • Inter-gateway interference management and admission control for a CDMA satellite communications system

    An approach for inter-gateway interference estimation and admission control is provided. A gateway receives return link signals, each being received via a satellite from a respective user terminal (UT) located within a satellite beam serviced by the gateway. A transmit power factor and an interference factor are determined for each UT based on the respective return link signal. A total interference factor is determined for the UTs based on the transmit power factors and the interference factors. A residual capacity level for the satellite beam is determined based on the total interference factor and a noise power factor. The gateway receives an admission request from a further UT requesting admission for transmission of a return link signal. The gateway determines whether to grant the admission request based on a required capacity level for the return link signal of the further UT relative to the residual capacity level.
