Title: Method and apparatus for proxied signalling of an end to end connection across a connection oriented network
Inventor: BOSLOY JONATHAN L
IPC: H04Q3/00
Filed: 1999-07-08
Abstract: There is provided a method and apparatus for establishing a connection across a connection oriented network to enable communication between an originating network element and a destination network node. The originating network element is connected to source network node in the connection oriented network by a source communications channel which is addressable in the connection oriented network. The connection oriented network has a signalling infrastructure employing a network signalling protocol for establishing connections within the connection oriented network. A connection establishment request message is generated for requesting the establishment of the connection between the originating network element and the destination network node and includes information identifying the source and destination communications channels. A proxy connection establishment request message is sent from a network controlling element to the connection oriented network over a proxy signalling link provided therebetween. The proxy connection establishment request message is received at the connection oriented network and the channel identifying information is extracted from the proxy connection establishment request message. A network connection establishment request message according to the network signalling protocol is then generated and sent over the signalling infrastructure to establish a path between the source network node and the destination network node. The path is connected to the communications channel identified in the proxy connection establishment request message, thereby establishing the connection between the originating network element and the destination network node.

IPC: H04L12/56
Filed: 1998-01-30
Abstract: A method is disclosed for improving the efficiency of the packet data channel by providing means for interrupting transmissions from or to a first mobile station so as to allow a short message to be communicated between the communication system and a different mobile station. The packet channel feedback information includes several flags:  Received/Not Received (R/N); Partial Echo (PE); and Partial Echo Qualifier (PEQ). The PEQ allows the communication system to interrupt the transmission to one mobile station to send a short message to another mobile station. By setting the PEQ to various values, a mobile station can determine whether subchannel ownership has been temporarily interrupted and reassigned to another station.

Patent CA-2285098-A1 (CA)
Inventor: SIMMONS MICHAEL RALPH
IPC: G06F12/06
Filed: 1999-10-06
Abstract: A method and apparatus are disclosed for automatically determining system configuration information, including the sector, carrier frequency and bus assignment of each hardware component installed on equipment, such as a cell station. In an illustrative cell station implementation, each cell station includes a hardware controller that communicates on a common bus with a plurality of hardware components. When each cell station is powered up or reset, each hardware component reads an identification value (or a portion thereof) that has some physical significance from a backplane on which the hardware component is installed. The identification information obtained from the backplane is used to derive a bus address that uniquely identifies each hardware component on the common bus. In addition, the identification information contains information that describes the hardware component and how the component is located within the cell station. In the illustrative embodiment, the identification value identifies the carrier frequency, frame, sector number (such as .alpha., .beta., .gamma.), unit type and unit number associated with the hardware component.  The hardware component can provide information to the hardware controller that allows the hardware controller to generate a map of the hardware components located within the cell and determine their interconnection.

Patent CA-2287166-A1 (CA)
Title: Imaging system
Inventor: HIROSE YOICHI
IPC: H04B10/00
Filed: 1999-10-22
Abstract: An imaging system includes an images outputting an analog green signal, an analog blue signal, and an analog red signal in a predetermined progressive-scanning format. The analog green, blue, and red signals are converted into parallel-form digital green, blue, and red signals, respectively. A set of the parallel-form digital green, blue, and red signals is converted into a set of a parallel-form digital luminance signal, a first parallel-form digital color-difference signal, and a second parallel-form digital color-difference signal. A signal divider separates the parallel-form digital luminance signal into a first sub parallel-form digital luminance signal and a second sub parallel-form digital luminance signal. The first and second sub parallel-form digital luminance signals are converted into a serial-form digital luminance signal. The first and second parallel-form digital color-difference signals are converted into a serial-form digital color-difference signal. A first electric-to-optical converter converts the serial-form digital luminance signal into a first optical signal having a first predetermined wavelength. A second electric-to-optical converter converts the serial-form digital color-difference signal into a second optical signal having a second predetermined wavelength different from the first predetermined wavelength. An optical multiplexes multiplexes the first optical signal and the second optical signal into a multiplexed optical signal, and outputs the multiplexed optical signal to an optical transmission line.
