Conversion Between Signaling Protocols Patents (Class 370/467)
  • Publication number: 20120155490
    Abstract: A process transfers data packets through a protocol stack employed by a device that transmits packets on a packet connection to a wireless network between at least two, distinct wireless access technologies such as GSM/GPRS and UMTS. A first layer of the stack stores a copy of a transferred packet until confirmation is received from a next, lower layer of successful transfer of the packet of the stack. In the absence of such confirmation and on the occurrence of a switch of the packet connection to a new connection path, particularly one of a different wireless access technology, the stored packet is transferred to the protocol stack to be employed by the wireless device for the new packet connection path. Consequently, the packet transfer process avoids packets being lost on the occurrence of a switch between different technology wireless access packet connection paths.

  • Patent number: 8125983
    Abstract: An exploitation of the proper classification of conventional call processing states into categories, each category corresponding to one of the call states of the SIP finite-state machine (FSM), yields simplified design, implementation, and operation of heterogeneous call processing. A separate FSM for the SIP-categorized call states running in parallel with a conventional port event processing (PEP) FSM, implements a VoIP Local Call Controller by passing events between the SIP-type FSM and the PEP FSM only at the points where a transition between SIP categories occurs. The SIP FSM does not require notification of PEP FSM transitions not affecting the SIP call state. For this reason, none of the code associated with the transitions between PEP FSM states within the same major state category requires any modification. Consequently the integration of VoIP and PEP call processing can be done more simply, and at dramatically-reduced cost in software development, support, and maintenance.

  • Patent number: 8102989
    Abstract: Gateways facilitate communication of voice traffic from a calling party to a called party over a packet network. To establish a communication session, an originating gateway sends one or more initial call control messages using overlap signaling to a destination gateway. The destination gateway may be unable to establish the communication session using overlap signaling. The destination gateway signals the originating gateway, such as by indicating that the communication session could not be established because of an incomplete or invalid destination address. The originating gateway then attempts to establish the communication session using en bloc signaling. In this way, an attempt that fails due to the use of overlap signaling is retried using en bloc signaling.

  • Patent number: 8073331
    Abstract: According to one embodiment of the present invention, a wavelength-shifted dynamic intelligent bidirectional access optical system utilizes key optical elements such as: a quantum dot enabled semiconductor optical amplifier, a phase modulator and an intensity modulator to provide upstream optical signals. These key optical elements reduce the Rayleigh backscattering effect on the transmission of optical signals. to enable a longer-reach access network topology between a subscriber unit and a super node (e.g., many local nodes collapsed into one super node). Such a longer-reach access network topology eliminates operational and capital costs related routers and switches. Furthermore, a wavelength to a subscriber unit may be protected and dynamically varied for on-Demand bandwidth, information and services and also a subscriber's unit may be configured with any array of connectivity options.
