  • Patent number: 8693462
    Abstract: Combinational networks provide simultaneous connectivity via networks of different network type between user equipment. For communication sessions on different network types, belonging to the same user equipment, a correlation check is enabled by introduction of an identifier denoted as Combinational Call Indicator (CCI). This CCI identifier in combination with the known Calling Line Identity (CLI) identifier enables user equipment and other and network entities to perform a correlation check between ongoing, or to be established, CScalls and PS-sessions. A user equipment, setting up a related communication session, sets the CCI identifier and provides the CCI identifier during the communication session setup towards the receiving user equipment or network entity, which is enabled to check whether the last received communication session is correlated to the earlier established session due to the presence of the CCI identifier.

  • Patent number: 8693473
    Abstract: A device identification server identifies a “household” to which a particular device belongs by associating the device with a LAN MAC address of the router through which the device connects to a wide area network such as the Internet because the LAN MAC address (i) is unique to the router and (ii) is not readily discoverable by interaction with the router through the wide area network, impeding spoofing by malicious entities. The device queries and receives the LAN MAC address of the router through the local area network. The device passes the LAN MAC address of the router along with its digital fingerprint to the device identification server. Devices that report the same LAN MAC address of the router through which they connect to the wide area network are determined to be from the same “household”, i.e., to be managed by one and the same entity.

  • Patent number: 8693476
    Abstract: A method and apparatus for dynamically modifying routing information in an interconnect architecture without quiescence is herein described. Each agent/node holds routing information regarding target agents/nodes in an interconnect architecture, which may include routing preferences. When a node is to be hot removed, it generates port disable messages to neighbors. The neighbors disable a port the disable message is received on and generates a completion message back to the not to be removed. The node to be removed continues to route messages until it receives a completion; at which time it disables a corresponding node. When all nodes are disabled the device may be removed. Other nodes in the interconnect architecture learn of an agent removal through use of return cycles when messages reach dead ends during attempted routing of cycles. Furthermore, hot addition of a node includes broadcasting of an enable message to enable nodes for routing to the added node.

  • Patent number: 8693493
    Abstract: The embodiments relate to modeling wireless communications in a network. In wireless communications, the nodes share one or more wireless communication channels. When a node has data to transmit, it must contend with the other nodes for access to the wireless communication channel. In the embodiments, the model is configured to simulate the throughput effects of contention including delays caused by retransmissions due to interference and collisions, listen-and-backoff, unavailability of time slots, etc. The occurrence of failed/dropped transmissions due to buffer overflows, excessive retransmission attempts, and unintended collisions are modeled as well. In addition, the embodiments may simulate the effect of mobility by the nodes and the effect of the location of the nodes relative to each other.

  • Patent number: 8693499
    Abstract: A client in a media session periodically transmits a “keepalive” message that indicates that a new amount of bandwidth is requested for the in-progress media session. A bandwidth policy service receives the keepalive message and determines whether the new amount of bandwidth can be allocated to the in-progress media session. If the service determines that the new amount of bandwidth can be allocated to the session, the service transmits a response to the keepalive message that indicates that the new amount of bandwidth has been allocated to the media session. The client receives the response and adjusts the bandwidth utilized by the in-progress session to the new amount of bandwidth.

  • Patent number: 8693501
    Abstract: A method for data encoding and associated decoding is based on the concept of batches that allows transmission of a large data file from a source node to multiple destination nodes through communication networks that may employ network coding wherein sparse matrix codes are employed in a network setting. A batch is a set of packets generated by a subset of the input packets using sparse matrix encoder. A sparse matrix encoder can be called repeatedly to generate multiple batches. The batches are generally independent of one another. During the transmission in a communication network, network coding can be applied to packets belonging to the same batch to improve the multicast throughput. A decoder recovers all or at least a fixed fraction of the input packets using received batches. The input packets can be pre-coded using a pre-code before applying sparse matrix codes. The data file can then be reconstructed by further decoding the pre-code.

  • Patent number: 8693504
    Abstract: Customizable, multimedia messaging over a subscriber television system utilizing a service independent framework is provided. A multimedia messaging (MMM) server is generally located at a headend of a cable or satellite system, and an MMM client at a communications terminal located remotely with respect to the MMM server. A service provider or operator defines a message configuration to present the message content to subscribers. The message configuration includes parameters that control the presentation of the message content. The MMM server receives an MMM request from a service application, and generates an MMM request which is sent to the communications terminal, particularly, to the MMM client. The MMM client processes the MMM request, including retrieving message content and/or message configuration. The MMM client presents the message to the subscriber. Since the MMM server and MMM client are platform independent, different services may send uniquely generated and designed messages for presentation.
