摘要： Computer-implemented methods for power management of network interface devices are disclosed. Such methods may include dividing a time period into a plurality of time slots, determining an amount of data received by the network interface device during a first of the time slots, and determining whether the amount of data received exceeds a predefined threshold. If the amount of data received exceeds the predefined threshold, then the network interface device is caused to be awake during a subsequent time slot. The network interface device is caused to go to sleep during the subsequent time slot unless the amount of data received exceeds the predefined threshold. A number of the time slots may be defined as wakeup time slots during which the network interface device is awake. The number of time slots during the time period in which one or more packets were received by the network interface device may be compared to the number of wakeup time slots during the time period. Based on the comparison, the number of wakeup time slots may be adjusted for a subsequent time period.

摘要： A system and method for improved vertical handoff between different types of wireless network. Network allocation vector occupation and packet collision probability are used as quality of service measures, enabling vertical handoffs to be delayed until actually beneficial to quality of service. Improved wireless network cell boundary detection in vertical handoff scenarios is achieved with a Fourier-based technique in conjunction with an adaptively determined minimum operating signal strength threshold. Improved wireless network cell boundary detection enables vertical handoffs from high quality of service networks to be delayed as long as possible. Together, practical wireless network quality of service measures and improved detection of wireless network cell boundaries in vertical handoff scenarios reduce the rate of unnecessary vertical handoff resulting in higher overall quality of service experienced by a mobile computing device roaming between wireless network types.

摘要： Orthogonal pulse polarity modulation involves wireless communication in which the polarity of modulating pulses are set responsive to positive and negative character values of a corresponding code sequence. In a described implementation, data is converted to chip waveforms, spectrum lines are removed, and pulses are appropriately shaped. For example, a data bit stream may be converted into chip waveforms using a bit stream-to-symbol segmenter, a symbol-to-code sequence mapper, and a code sequence-to-chip waveform transformer. The polarities of respective individual chips in a given chip waveform match the signs of respective individual characters in a corresponding code sequence.

摘要： A hardware-independent proxy layer for synchronous processing of commands in a mobile telephone is disclosed. Such synchronous processing may include receiving a function call of an application program interface (API) that is associated with a function to be performed by a mobile telephone, waiting to receive from a driver layer a result notify event indicating that the function has been performed, and, after receiving the result notify event from the driver layer, passing to the client first result data associated with the first result notify event. The API may be translated into an input/output control (IOCTL) code, which may be sent to the driver layer.

摘要： A UMTS extension to the GSM/GPRS RIL is disclosed. The UTMS RIL provides an API set interface for the support of UMTS features such as 3G QoS, secondary PDP contexts call, priority service, voice group call and voice broadcast services, etc. The API set is based on the UMTS AT command interface as defined in 3GPP specification TS 27.007. The architecture of the UMTS RIL is designed as a standard interface with APIs and callback mechanisms that can be used across different platforms and multi-radio hardware such as GSM, GPRS, WCDMA, and HSDPA. The UTMS RIL may enable various applications running on mobile platforms in 2G, 2.5G, and 3G cellular radio stacks to issue commands without knowledge of underlying radio hardware structure.
