Abstract: A method for injecting metadata into an existing artifact is described. The method generates metadata related to an existing artifact having a predetermined structure and encodes the metadata in accordance with the predetermined structure. The encoded metadata is embedded within the existing artifact in accordance with the predetermined structure and is delineated within the predetermined structure as one or more individual records. The artifact, including embedded metadata, is stored within a storage entity and is accessible to processes related to the artifact. Additional records may be generated and embedded over time, thus creating a timeline if event related to the artifact.

Abstract: Methods for providing full duplex media service over a communications network employing simplex media paths are presented including: establishing a simplex media path and session over a terminal using a communication protocol; establishing an additional simplex media path and session over an additional terminal using the communication protocol; and utilizing the simplex media path and session with the additional simplex media path and session to provide full duplex media service between the terminal and the additional terminal. In some embodiments, after establishing the additional simplex media path and session, processing media on the additional terminal. In some embodiments, the communications network is a Push-to-Talk over Cellular (PoC) network and the simplex media path and session and the additional simplex media path and session are Push-to-Talk (PTT) sessions.

Abstract: An apparatus for performing XML processing distributed across one or more network entities and a terminal comprised of a mobile device entity. A memory stores a transformed representation of XML information. The network entity and terminal communications are mediated by a proxy tasked with offloading XML processing other operations from the network entities or terminals participating in communications exchanges and/or XML manipulations. Advantages of the invention include the ability for network operators to optimize communications techniques based on XML Documents, XML Fragments, communication protocol components, and other forms of XML interchange and exchange.

Abstract: An apparatus for communicating between an access endpoint and a mobile device endpoint comprising a network service center attached to the access endpoint. A memory stores a prototype corpus representing historical communication information. The network service center includes a processor to train the prototype corpus and create a plurality of records including a protocol trigger, training data and a user dictionary. The access endpoint sends the training data to endpoints to produce training data specific to classes of endpoints. The access endpoint and the mobile device endpoint communicate with one another, and the network service center collects communication data related to the communications interaction and stores the communication data in the memory. The processor generates feedback data based at least in part of the communication data. Advantages of the invention include the ability for network operators to optimize communication techniques based on network traffic.
