Abstract:
A method for implementing Short Message Service (SMS) in a wireless communication network may be implemented by a mobile station. The method may include sending mobile-originated SMS data while in idle mode. Ranging procedures may be used to send the mobile-originated SMS data. The method may also include receiving mobile-terminated SMS data while in the idle mode. Receiving the mobile-terminated SMS data may include receiving a broadcast page message from a base station, and the broadcast page message may include an identifier for the mobile station.
Abstract:
Methods and apparatus for establishing multiple connections between a wireless device and multiple base stations and transferring data using these connections via different segments of an orthogonal frequency division multiple access (OFDMA) frame are provided. The multiple connections may be used for multi-way (e.g., three-way) concurrent processing, multi-way (e.g., three-way) handover, or a hybrid between concurrent processing and multi-way handover in an effort to increase data throughput for the wireless device.
Abstract:
A method for controlling communications traffic on an inter-access-network link includes receiving a request for transmission of a traffic flow and determining a priority queue associated with the traffic flow. If the priority queue corresponds to the one of a first plurality of priority levels, the method further includes determining whether one or more predetermined criteria for the traffic flow are satisfied. If yes, the method additionally admitting the traffic flow, storing information associated with the traffic flow in the queue, and transmitting information associated with the traffic flow from the queue based on at least a strict priority process. If the queue corresponds to the one of a second plurality of priority levels, the method further admitting the traffic flow, storing information associated with the traffic flow in the queue, and transmitting information associated with the traffic flow from the queue based on at least an arbitrated priority process.
Abstract:
An optical disk drive includes a motor base, a rotating shaft, a rotor and a disk mounting structure. The rotating shaft is rotatably disposed on the motor base. The rotor is disposed on the rotating shaft with part of the rotating shaft protruding from the rotor. The disk mounting structure includes a mounting portion, a fitting portion and a ball. The mounting portion is disposed on the rotating shaft for carrying an optical disk. The fitting portion is disposed on the mounting portion to be buckled into the hole of the optical disk. The lateral surface of the fitting portion has a cavity. The ball is movably disposed inside the cavity and may be pulled or attracted by a predetermined pulling force. When the disk mounting structure rotates, the ball will press the optical disk because the centrifugal force of the ball is larger than the predetermined pulling force.
Abstract:
A power plug of a peripheral device for electrically connecting a socket is provided. The power plug includes a first plug pin, a second plug pin, a third plug pin and a fourth plug pin respectively protrude a first length, a second length, a third length and a fourth length from a datum plane of the power plug. The second length is larger than the first length, the third length is substantially the same with the second length, and the fourth length is smaller than the second length. While the power plug is electrically connected to the socket, the second plug pin and the third plug pin respectively contact a second socket pin and a third socket pin first, and then the first plug pin and the fourth plug pin respectively contact a first socket pin and a fourth socket pin to generate an electrical connection.
Abstract:
An optical drive having LED indicator with variable brightness. The optical drive comprises a light emitting diode indicator with variable brightness and a volume knob. The brightness of the light emitting diode indicator varies with the volume of the optical drive when the volume knob is rotated. The LED indicator can be disposed on a front panel of the optical drive or directly disposed in the volume knob.
Abstract:
A printed circuit board and an electronic apparatus utilizing the same. The electronic apparatus includes the printed circuit board and a dual-inline-package (DIP) device. The printed circuit board includes a pair of holes. The pair of holes has a geometrical center, and is substantially symmetrical with respect to the geometric center so that each hole is arc-shaped. The DIP device includes a pair of pins, and is disposed on the printed circuit board by inserting the pins into the holes.
Abstract:
A method and apparatus for operating a cellular telephone system that supports performing an inter-system soft handoff is described. A subscriber unit generates a pilot strength measurement report when the pilot channel from a base station is detected. When a base station controller receiving the pilot strength measurement report determines that the base station is part of a second cellular telephone system, a inter-system soft handoff request is generated. An admission control subsystem receives the inter-system soft handoff and either grants or denies the request base on the traffic level with the second cellular telephone system. In a preferred embodiment of the invention, the traffic level is determined based on link load messages received periodically by the admission control subsystem that are generated by an interface port coupled to an interconnect between the first cellular telephone system and the second cellular telephone system. The link load message include peak queue length and average frame rate information.
