  • Patent number: 8208442
    Abstract: The present invention allows calls that are controlled by a multimedia subsystem (MS) to employ bearer paths that are supported in whole or in part by a circuit-switched subsystem (CS). As such, calls controlled by the MS can have a portion of the bearer path provided through the CS when needed or desired. To facilitate such control, a session control signaling path is established between a user element currently supported by the CS and a remote user agent (RUA), which represents the user element in the MS. While a portion of the bearer path for the call is supported by the CS, the session control signaling path extends the reach of the MS to the user element.

  • Patent number: 8194597
    Abstract: Cellular signals or other wireless signals/messages are introduced into a building or to an outside location by transmitting packets corresponding to those signals over a data network and low cost cables to designated locations within the data network. Once the designated packets containing the signals reach the destination, they are then broadcast over the air to a terminal capable of receiving the wireless message. In a first embodiment, an in-building gigabit Ethernet network, such as that currently existing presently in many buildings, is used to distribute radio signals indoors. Instead of transmitting the radio signals over the air from a repeater connected to a base station, coded baseband signals generated by the coding processor (e.g., a CDMA Modem Unit) in the base station are packetized and sent over the Ethernet network to radio processing equipment and antennas distributed throughout the building.

  • Publication number: 20120033662
    Abstract: A crossbar switch has N input ports, M output ports, and a switching matrix with N×M crosspoints. In an embodiment, each crosspoint contains an internal queue, which can store one or more packets to be touted. Traffic rates to be realized between all Input/Output (IO) pairs of the switch are specified in an N×M traffic rate matrix, where each element equals a number of requested cell transmission opportunities between each IO pair within a scheduling frame of F time-slots. An efficient algorithm for scheduling N traffic flows with traffic rates based upon a recursive and fair decomposition of a traffic rate vector with N elements, is proposed. To reduce memory requirements shared row queue (SRQ) may be embedded in each row of the switching matrix, allowing the size of all the XQs to be reduced. To further reduce memory requirements, a shared column queue may be used in place of the XQs.

  • Patent number: 8107465
    Abstract: A media gateway is coupled to an Internet Protocol (IP) network through a router. The router and the media gateway communicate through a slim protocol that allows the media gateway to reserve connections over the IP network that have certain minimum bandwidth and latency attributes. The router handles the obtaining of the requested IP circuit for the client. The media gateways only need to execute a relatively simple client application and do not have to be independently capable of obtaining IP-QoS information from the IP network.

  • Patent number: 8085757
    Abstract: A telephone number of the callee is received from a caller device. An Internet protocol Multimedia Subsystem (IMS)-based telephone number mapping (ENUM) query is constructed based on the telephone number of the callee. An ENUM database is queried based on the ENUM query. If a response to the ENUM query is absent a Session Initiation Protocol (SIP) Uniform Resource Indicator (URI) or a telephone (TEL) URI, the telephone number is resolved into one or more non-SIP/non-TEL URIs usable to communicate with the callee. The caller is enabled to use the caller device or other devices to select which of the one or more non-SIP/non-TEL URIs to use to communicate with the callee. For each caller-selected non-SIP/non-TEL URI, communication in a protocol associated with the URI is initiated between the caller and the callee using the caller device or other devices.
