When individual persons or vehicles move through a transportation network, they are likely to be both actively and passively creating information that reflects their location and current behavior. In this patent, we propose a system that makes complete use of this information. First, through a broad web of sensors, our system collects and stores the full range of information generated by travelers. Next, through the use of previously-stored data and active computational analysis, our system deduces the identity of individual travelers. Finally, using advanced data-mining technology, our system selects useful information and transmits it back to the individual, as well as to third-party users; in short, it forms the backbone for a variety of useful location-related end-user applications.

The present invention provides a hybrid central / distributed and tiered video on demand (VOD) service network with tiered content structure. In particular, the present invention uses media servers located in both the headend station and the hub stations. Set-top boxes generally would be supplied VOD services from the high-demand content media servers located in the hub station nearest to the user. The central media server located in the headend would be used as an installed backup to the hub media servers; as the primary source for lower demand VOD services and as the source of the real time, centrally encoded programs with PVR (personal video recorder) capabilities.By distributing the servers to the hub stations, the size of the fiber transport network associated with delivering VOD services from the central headend media server is reduced. The invention provides that each user has access to several server ports located on at least two servers. Multiple paths and channels are available for content distribution to each user, assuring high system reliability and enhanced asset availability. Substantial cost benefits are derived from the reduced need for a large content distribution network and the reduced storage capacity requirements for hub servers.

The present invention relates to methods and an arrangement for receiving, storing, and originating multimedia messages. An incoming message is transmitted to an in / out interface via a transport network. The message is stored in a message store, translated in a translation unit into a format adapted to the presentation capabilities of receiver's current terminal and delivered to the receiver over a user access interface and an access network with guidance from a location database. Earlier received messages, which are kept in the message store, can be accessed and edited via any standardized access network using media translation in the translation unit. A multimedia message is originated by a user in the system via any access network and the user access interface. The message is then stored in the message store, translated in the translation unit, and delivered to the destination through the in / out interface and an appropriate transport network.

A method, apparatus and network for transporting layer-2 frames, such as Ethernet MAC, ATM AAL5, and Frame Relay, over SONET, SDH, or OTN transport networks is disclosed. The method establishes “pseudo-wires” between, for example, SONET switches and directly on top of the SONET layer.

This approach provides a number of advantages to the network carriers in terms of operation and equipment expense reduction. To enable the transport network to be independent from IP and MPLS, and avoid subsequent IP control message processing inside the networks, an edge-to-edge “tunneling” mechanism is designed to transmit control messages as a part of the SONET (or SDH or OTN) frame payload.

Responsive to a triggering event, the CES and one of the resources (the same or another resource) dynamically establish a second media channel between one another over the transport network. With the second media channel established, the conforming emergency system and the resource exchange messages over the second media channel to facilitate the CES in handling emergency events. The first media channel may be torn down.

A method for protecting the flows of traffic against, and for restoring them from, a failure in a multifunctional, hybrid broadband access-and-transport network system includes the provisioning of at least two Virtual Flows (“VFs”) of traffic between each pair of ingress and egress (“I / E”) nodes in the system. The at least two VFs are provisioned such that each takes a different physical path from the other. The VFs taking the same physical path are then respectively grouped into two “Path Protection Groups” (“PPGs”). Each of the PPGs has a dedicated “Management Control Flow” (“MCF”) provisioned within it that is carried in the at least one VF contained therein. The detection of a fault in the traffic in an “active” PPG results in the generation of a protection switching signal (“PSS”) being generated and sent by the nodes detecting the fault along the MCF of the affected PPG to the relevant “protection switching entities” (“PSEs”), i.e., the affected I / E nodes, which responsively effect a protection switch of either the reception, or both the transmission and the reception, of the affected traffic from the affected “active” PPG to the associated “protect” PPG to thereby restore path and traffic continuity within the system. The method is independent of the transport layer and can thus be used to protect traffic in networks having transport systems other than SONET.
