  • Patent number: 9977838
    Abstract: The invention introduces a method to inform/configure a peer-to-peer application environment such that an application can find good alternatives for peer selection and data exchange taking the network configuration conditions including caching strategies and deployment into account. In use, a mobile operator stores a tracker file that is used to provide information of likely locations of a data file sought by an end user. The mobile operator provides instructions to a mobile communication device of the end user regarding the location of a tracker file that is available for use by said mobile communication device. In this way, the mobile operator controls the peer-to-peer environment available to the end user.

  • Patent number: 8989737
    Abstract: A system is provided for establishing a communication session with a terminal (i.e., terminating SIP client). The system includes a network node (e.g., SIP proxy) located in a network across which an originating client is capable of communicating. The network node is capable of sending a trigger to the terminal independent of the network. The network node is also capable of receiving a registration message, in response to the trigger, from the terminal across the network. In this regard, the network node is capable of receiving the registration message to thereby identify the terminal across the network such that a communication session is capable of being established with the terminal based upon the identity of the terminal across the network.

  • Publication number: 20140136644
    Abstract: A method for caching data is disclosed, in which a network apparatus (401) partitions (600) the data into chunks to be stored in at least one priority cache and in at least one secondary cache. In response to receiving (602), in the network apparatus (401) a content request message (601) related to a user terminal (403), the apparatus checks (602) whether prioritized chunks of the requested content are available in a priority cache, the apparatus transmits (603) the prioritized chunks of the content from the priority cache to the user terminal (403). The apparatus (401) also retrieves non-prioritized chunks of the content to the priority cache from a secondary cache, wherein the retrieved non-prioritized chunks are transmitted (605) to the user terminal (403).

  • Patent number: 7907954
    Abstract: A system and method for dynamically instantiating a communication interface between a requesting entity and a client entity. A requesting entity transmits a trigger signal to a control point, where the trigger signal includes a preferred communication configuration. The control point inspects the preferred communication configuration and, if possible, instantiates a communication link that complies with the requested configuration. The communication link is deactivated either in response to a timing function, upon determining that the requesting and client entities have completed their data exchanges, or determining that an amount of time provided for the communication has expired.

  • Patent number: 7747731
    Abstract: The present invention concerns a method and a system for minimizing message processing latency in a communication network. A message from a first node is received at a second node which message requires an acknowledgement message, preferably of Boolean type. Functionalities required for processing the message are partitioned into at least a first part and a second part. The first part comprises a minimum set of functionalities required to generate the acknowledgement message. The functionalities of the first part are executed. The acknowledgement message is generated and transmitted to the first node after to finishing the functionalities of the first part. The present invention makes it possible to effectively minimize the perceived message processing latency. It is also possible to dynamically optimize the latency according to available resources.

  • Patent number: 7599374
    Abstract: A system for establishing an Internet Protocol (IP) connection with a terminating node includes an originating node capable of initiating communication with the terminating node. The system also includes an intermediate node located between the originating node and the terminating node. The originating node is capable of initiating communication by either (a) requesting communication with the terminating node via the intermediate node, or (b) notifying the terminating node of incoming data independent of the intermediate node. In this regard, when the originating node initiates communication in accordance with (a), either the originating node or the intermediate node is capable of notifying the terminating node of incoming data. Upon being notified of incoming data, then, the terminating node is capable of registering with the intermediate node to thereby establish an IP connection between the originating node and the terminating node via the intermediate node.

  • Patent number: 7502923
    Abstract: Systems, devices and methods are presented for providing controlled use of information stored publicly within the domain name system (DNS). Controlled use is established by storing encrypted data at the DNS servers and establishing trust, in the form of transfer of keying material, with requisite parties. The invention provides backward compatibility with existing DNS servers, in that, it provides for storage of encrypted data in existing resource records. The invention benefits from allowing storage in the DNS to be divided into both public and private classification, such that a user can identify and store certain public information that is available to all parties that have access to the DNS, while other information that has been classified as private is only available to parties which have established a trust.
