摘要： Methods and apparatus for non-disruptive upgrade by redirecting I/O operations. With this arrangement, a driver upgrade does not require restarting an application. In one embodiment, a method includes installing on a computer a legacy upgrade module in a kernel having a legacy driver with first and second loadable extensions for handling input/output operations for applications to and from devices, retrieving and storing static configuration data from the legacy driver, transferring the stored static configuration data to a new driver, obtaining runtime device configuration data from the devices and transferring the runtime device configuration data to the new driver, and filtering device input/output operations such that prior to cutover input/output operations are directed by the LUM through device stacks for the legacy driver and after cutover input/output operations are directed to the new driver.

摘要： An improved technique for handling events in a multipathing driver employs an event queue and a queue manager that run in the kernel of a computing system. The queue manager receives events raised by the multipathing driver, as well as events raised by software constructs, such as application programs. Records of events are added to the event queue in the order the queue manager receives them. Event records may be consumed chronologically by external software. Preferably, the event queue is sufficiently large to store all events arising out of most predicted fault scenarios. Also, the queue manager is sophisticated and can perform certain diagnostic and analysis tasks without the aid of external software.

According to the technical solutions provided in the present invention, the system can provide high-quality mobile multimedia services for users in a 6 MHz operation bandwidth. Furthermore, an optimized selection is performed on RS coding according to the operation bandwidth of the system, thereby selecting an appropriate coding mode according to different channel conditions. Accordingly, the byte interleaver is optimized, such that suitable interleaving parameters can be used to perform byte interleaving. With the technical solutions provided in the present invention, the continuous pilots, the discrete pilots and the digital sub-carriers of the system can be suitably configured and allocated according to the actual bandwidth of the system, thereby suitably configuring the system overhead of the mobile multimedia broadcast transmission system to efficiently utilize spectral resources for data transmission.

摘要： A method for transmitting control information to indicate a receiver, comprising following steps: the control information is formed at transmitting side and is encoded based on the working status of the transmitting side of the system; after the encoded control information is mapped, it is multiplexed with other pilot symbol and service load, then an OFDM symbol is generated; the OFDM symbol is transformed from frequency domain to time domain, then a time domain sampling signal is obtained and transmitted to the receiving side of the system; at the receiving side, the time domain sampling signal transmitted by the transmitting side is received and transformed from time domain to frequency domain to form OFDM symbol; the control information is obtained from the valid sub carrier of the OFDM symbol, and the control information is decoded; each work information is extracted form the decoded control information, and the receiving terminal is indicated to execute respective receive process based on the extracted work information. The method can ensure the receiving terminal to receive data based on its own expectation, then reduces the work power consumption of the receiving terminal, and saves the run cost of the digital broadcast system.
