A method to systematically analyze a next generation telecommunications network to result in creating a provisioning plan for provisioning the network to provide services for one or more subscribers. In one specific embodiment, the method involves creating and storing information that represents a logical decomposition of the next generation network into a plurality of discrete functional areas. The information representing the functional areas is analyzed to identify one or more provisioning requirements for each of the functional areas. One or more provisioning procedures are determined, and one or more required provisioning tools are identified for each of the functional areas, based on the provisioning requirements. A sequence of execution of the procedures and tools is created and stored as a provisioning plan.

Some embodiments are implemented in a communication system that includes a first wireless communication system and a second wireless communication system that includes a Femtocell access point (FAP) and a network controller that can communicatively couple the FAP to the first wireless communication system. In some embodiments, the network controller can communicatively couple to the first wireless communication system through a UTRAN Iu interface. Some embodiments provide a method for performing discovery. The method sends a discovery request message that includes a licensed wireless cell information to a provisioning network controller. The method receives a discovery accept message at the FAP. The discovery accept message includes identification of a default network controller determined based on the cell information. The discovery accept message is sent by the provisioning network controller when the provisioning network controller determines that the provisioning network controller can accept the discovery request message.

A method is disclosed for carrying out network device provisioning and configuration, and communication of other information to a network device, automatically and in an assured manner. A configuration service receives a request from a network device to provide configuration information. The configuration service retrieves a template representing the configuration from a storage location, e.g., a directory service. The configuration service also retrieves one or more parameter values specific to the device. Device-specific values are instantiated for the generic parameters in the template, based on the retrieved values. The resulting configuration is stored in XML format using XML tags to delimit configuration commands, tested for well-formed-ness, and syntax checked. A reliable transport protocol carries the configuration information to the device. At the device, a configuration agent syntax checks the embedded configuration information, and then applies the configuration information to the device. As a result, automatic network provisioning may be accomplished remotely, without requiring a skilled technician to visit customer premises to carry out configuration. The process may be integrated with an event service to enable multiple devices to concurrently receive re-configuration without special synchronization logic.

A supply chain network where customers, suppliers, logistics providers, carriers, and financial institutions are all connected to a centralized supply chain server. The server receives forecasts from the customers detailing the orders that the customers desire. These forecasts are analyzed by the supply chain server to ensure that they conform to contractual agreements and do not contain errors. The forecasts are also used to warn the suppliers of future demands so that the suppliers can anticipate demands and plan inventory accordingly. Once supplier demand issues are resolved, the forecasts are sent to the suppliers in groups so that the suppliers prepare a smaller number of large orders. The supply chain server also controls the processes involved in distributing the product from the suppliers to the customers including the generation and payment of invoices. A form of financing the customers' purchases, made possible by the supply chain architecture, is also disclosed.

Wind power installations were initially always erected in the form of individual units and it is only in recent years that, caused also by administrative and building regulations, wind power installations are frequently installed in wind parks. In that respect a wind park in its smallest unit is an arrangement of at least two wind power installations, but frequently markedly more.

By using MP-BGP messages to exchange PBB interface information between nodes, peering relationships are established, and communities may be built with any desired topology. Previously, PBB has only been used as a connectionless bridge; embodiments of the present invention use PBB as a connection between edge nodes. Network designers are provided increased flexibility, and security and congestion are improved, benefiting end users.
