  • Patent number: 11627119
    Abstract: The present invention provides methods, apparatuses, and systems for delivering protected streaming content to a receiving device. In an aspect of the present invention, a broadcaster provides streaming content. To ensure viewers are properly authorized, the streaming content is encrypted with a traffic key. The traffic key is provided to the users via a key stream message, which is encrypted with a service key. The user obtains at least one rights object from a rights issuers and the at least one rights object includes the service key so that the streaming content may be used. The at least one rights object also contains information regarding usage rights that may be configured by the rights issuer so that, depending on the user and/or the receiving device, different rights may be available. The key stream message may include a program category variable value that indicates the type of content and in conjunction with the rights object, determines what usage rights exist for the streaming content.

  • Patent number: 10462618
    Abstract: To provide a possibility to have a near-real-time replay of a pre-empted communication while ensuring that the pre-empting communication is not interrupted, when it is detected that a pre-empting communication is pre-empting a pre-empted communication, the pre-empted communication is buffered to a buffer for a replay, and a safety interval for the pre-empting communication is determined. The pre-empting communication is determined to be ended in response to an expiry of the safety interval after end of the pre-empting communication.

  • Patent number: 9100857
    Abstract: A recovery scheme where a base station monitors state of interoperation with a primary exchange. When the primary exchange becomes unavailable, active services may be lost, but the base station sends an activation request message to a secondary exchange that has access to base station configuration information of the base station. The secondary exchange uses the base station configuration information to activate the base station, and user terminals in the base station cell may begin to registrate to the system. Recovery capability of communications can be achieved with optimized use of network resources.

  • Patent number: 8661078
    Abstract: A method for improved application of unreliable transfer mechanisms. An application uses application data delivered in data packets that become accessible from a peer entity via at least two packet data transmission mechanisms. The application is configured with a predefined operational range for a predefined application-specific characteristic. If the predefined application-specific characteristic exceeds the predefined operational range, the packet data transmission mechanism is changed. The mechanism facilitates maintaining an application-specific service level even if unreliable transmission mechanisms are applied.

  • Publication number: 20110196837
    Abstract: An information system that comprises a data source that transmits a data item to a group of database instances using a packet-switched communication protocol in which retransmission of the data item to a data base instance is independent from reception of an acknowledgement to the transmitted data item from the database instance. A database instance receives the data item from the data source, stores it as a present data item and opens access to the present data item. A data consumer queries information on the present data item from the database instance and is provided with means to detect whether the information included in a response to the query is valid or not. If the information is not valid, the data consumer initiates a new query from another destination.
