Abstract:
A coated fiber strand includes one or more coating layers located directly or indirectly on the strand and at least one heterogeneous region present in or on one or more of the coating layer(s). The heterogeneous region(s) preferably comprises a material useful for coding of the fiber. One particularly preferred embodiment relates to an optical fiber having a primary coating layer and a secondary coating layer where the heterogeneous region(s) defines one or more colored stripes in or on the secondary coating layer. A method for forming a coated fiber, such as an optical fiber, includes introducing at least one coating layer onto a fiber strand such that one or more coating layers directly or indirectly cover at least a portion of the surface of the strand. The method further includes introducing at least one heterogeneous region into or onto a coating layer(s). The fiber can then be treated, e.g., cured so as to provide a desired product. By this method, a desired functionality, e.g., coding, can be introduced onto a fiber without adversely effecting subsequent processing steps, e.g., curing of the coating layer(s).
Abstract:
Handoffs within a wireless communication system (20) include using a common cell definition code for each of a plurality of microcell BTSs (30, 40, 50) to facilitate handoffs between a macrocell (26) and any one of the microcells. In a disclosed example, a common cell definition code such as a PN offset or a scrambling code is used to trigger a handoff from the macrocell (26) to any one of the microcell BTSs (30, 40, 50). A mobile station locate feature identifies which of the BTSs is involved in the handoff. Another common cell definition code is used in one example to trigger all handoffs from any one of the microcells (30, 40, 50) to the macrocell (26). Soft handoff and hard handoff examples are disclosed.
Abstract:
In a waveguide grating router, a predetermined composite transmission spectrum output is achieved by eliminating loss imbalances through the use of variable loss elements (320). The variable loss elements are introduced to the waveguide grating router's waveguide ports (310), such that the loss of a transmitted signal is independent of wavelength. The waveguide grating router includes at least one input waveguide (302) and a plurality of output waveguides. The variable loss element is introduced to a predetermined group of output waveguides to produce a predetermined composite amplitude spectrum of the output signals. To provide a predetermined composite amplitude output spectrum, the variable loss elements may be implemented in a variety of ways, including a method of electrically controlling the router's waveguide ports to introduce more loss.
Abstract:
A method is provided comprising the following steps. A vehicle receives by radio from another vehicle an indication of speed of said another vehicle. The vehicle determines its own speed. A speed adjustment is automatically determined to be effected by said another vehicle so as to control relative speed of the vehicles. A speed adjustment request is transmitted by radio to said another vehicle.
Abstract:
A method for overload control between a first application and a second application based on Diameter protocol, comprising: when the first application is overloaded, overload control information is set and sent to the second application; and the second application takes an action according to the overload control information. The invention also provides a Diameter protocol based network element comprising an overload control initiating device configured to: set overload control information to be sent to an opposite network element communicating with the network element when overload happens. In addition, the invention further provides a Diameter protocol based network element comprising an overload control response device configured to: when receiving overload control information sent by the opposite side, take an action according to the overload control information.
Abstract:
The present invention discloses a communication method for transmitting multimedia data during a call between terminals. The method comprises: receiving a multimedia data transmission request initiated from one of the terminals in the call; and responsive to the request, transmitting the multimedia data to one or more of the terminals in the call.
Abstract:
The present invention proposed a new solution for providing the information in relation to the position of a subscriber terminal in a call-waiting queue to the subscriber terminal. The subscriber terminal generates a queue position information request message and sends it to a queue information serving device. After receiving the queue position information request message from the subscriber terminal, the queue information serving device obtains information in relation to the position of the subscriber terminal in the call-waiting queue and sends it to the subscriber terminal. And then the subscriber terminal informs the obtained information in relation to the position of the subscriber terminal in the call-waiting queue to the subscriber of the subscriber terminal. By applying the solution proposed by the present invention, the subscriber terminal needs not to wait for receiving the position related information passively and it can acquire its position related information initiatively at any time.
