摘要:
A dye sensitized solar cell, comprising a-heteroleptic polypyridil complex of Ru, Os or Fe. The donating ligand has an extended conjugated n-system increasing the light absorbance and keeing the LUMO energy level higher than that of the anchoring ligand. A compacting compound whose molecular structure comprises a terminal group, a hydrophobic part and an anchoring′ group may be co-adsorbed together with the dye on the semi-conductive metal oxide layer of the photoanode, forming a dense mixed self-assembled monolayer.

Systems and methods are disclosed to provide converged service control and converged charging in legacy networks and IMS networks. A converged service control system of the invention includes a protocol interface and a service controller. The protocol interface receives call messages from the legacy networks and the IMS networks, and converts the call messages to a common protocol. The service controller then processes the call messages in the common protocol to provide service control to the legacy networks and the IMS networks. The service controller is also enabled to provide online and offline charging for the legacy networks and the IMS networks.

An interactive voice response system (102) includes a protocol interface (134) that is adapted to communicate with a plurality of divergent telecommunications networks for voice communications (104, 106, 108, 110). These networks are, for example, a wireline telecommunications network, a CDMA network, a GSM network, and a voice over IP network. A controller (136) is coupled to the protocol interface to receive a plurality of common call control messages from, and to supply a plurality of common call control messages to, the protocol interface. The protocol interface converts control messages from each one of the plurality of divergent telecommunications networks into the plurality of common call control messages for the controller. The controller generates and receives the common call control messages to cause a prompt and collect interaction with a caller that is using a device that is coupled to one of the networks. The common call control messages generated by the controller are converted by the protocol interface into control messages that are appropriate for the particular network that is to receive the control message. That is, the common call control messages are converted to the network's protocol.
摘要:
IMS call control nodes and methods are disclosed for providing online charging in an IMS network. An IMS call control node receives a call message from a CSCF through a first interface for a call session, and determines whether to execute Application Server (AS) logic or gateway logic responsive to the call message. If the processing system determines that the call message should be processed with the AS logic, then the processing system executes the AS logic to perform a service and to contact the OCS for online charging for the service. If the processing system determines that the call message should be processed with the gateway logic, then the processing system executes the gateway logic to perform call session control and to contact the OCS for online charging for the call session.

Embodiments of the invention include a universal apparatus for incorporating intelligence into the distribution frame of an optical communication system. The communication system includes a distribution frame with one or more distribution shelves having one or more interconnection panels, and a universal operations, administration and maintenance (OA&M) apparatus attached to the distribution frame. The OA&M apparatus, which is operably connected to the interconnection panels and the distribution frame's system controller through an interface, monitors current interconnection panel connections including cross-connections and can indicate future possible cross-connections between interconnection panels. The OA&M apparatus also is useful for jumper routing, circuit administration, and other features associated with the distribution frame and its fiber connections.
