The present invention relates to a local communication wireless network system and the method thereof. When the wireless base station is not connected with the evolved packet core (EPC) server, the wireless base station can emulate the EPC server. The electronic devices connected to the wireless base station can connect to the emulated EPC server. The client unit of the wireless base station can collect the identification information of the electronic devices connected to the wireless base station, build an identification list, and send the identification list to the electronic devices connected to the wireless base station. Thereby, the electronic devices can send messages or perform digital voice or video calls to other electronic devices according to the identification list.

Local communication wireless network system and method thereof

The present invention relates to an offline-operable wireless network system and the method for operating the same. When a wireless base station is not connected to the evolved packet core (EPC) server, the wireless base station will emulate the EPC server. Thereby, the electronic device connected with the wireless base station can be connected to the emulated EPC server, so that the wireless network functions still can be applied in the offline state and a wireless local area network can be further built.

For decreasing seeks generated when switching an execution flow between commands to enhance read and write performances of a disc drive, a command is implemented with a specifically-designed data structure, and commands having neighboring physical addresses and the same type of read or write operations are grouped and linked together. With the aid of command groups, seeks between commands are significantly decreased, though starvation may arise. A few techniques are further provided for preventing starvation of command groups and for preserving the benefits of decreasing seeks.

A method of correcting corrupted primitives transmitted between a serial advanced technology attachment (SATA) host and a SATA device includes analyzing a current state, a previously transmitted primitive, or a previously received primitive; selecting at least one candidate primitive according to at least one of the current state, the previously transmitted primitive and the previously received primitive; predicting the identity of a current primitive according to at least one candidate primitive and a received current primitive; and replacing the corrupted primitive with the predicted primitive when the predicted primitive is different from the current primitive.

SATA primitive prediction and correction

A method for processing noise interference in a serial advanced technology attachment (SATA) interface. In the method, when a receiver does not receive a SOF primitive (start of frame primitive) but does receive an EOF primitive (end of frame primitive) or WTRM primitive (wait for frame termination primitive), the receiver outputs a R_ERR primitive (reception error primitive) to enable a transmitter to resend original data and thus to eliminate the interference. In addition, if the transmitter detects an error during the data transmission, a HOLD primitive (hold data transmission primitive) will be issued to temporarily stop the data transmission.

A method for processing noise interference in a serial AT Attachment (SATA) interface. The method includes the steps of detecting whether there is an error in CRC (Cyclic Redundancy Check) checksum or whether an R_ERR primitive (reception error primitive) is received, detecting whether a FIS (Frame Information Structure) is a data type if there is any error and returning back to error state detecting step if there is no any error, detecting whether the FIS is a ATAPI packet command CDB (Command Descriptor Block) when the FIS is the data format, and writing a special tag to the CDB and returning back to the error detecting step.

The invention discloses a signal detection apparatus and method thereof for detecting whether an input signal of a set of serial ATA signals is an out of band (OOB) signal. The signal detection apparatus includes a calibrated clock generation device, a signal processor, and a logic determination device. The calibrated clock generation device generates a sampling clock signal according to a predetermined clock signal.

A method and circuit for reducing SATA (Serial Advanced Technology Attachment) transmission data errors by adjusting the period of sending two consecutive ALIGN Primitives. The method reads a counting value of an 8b/10b coding error counter at a predetermined period and adjusts the period of sending two consecutive ALIGN Primitives according to the counting value. Because the system dynamically adjusts the period of sending two consecutive ALIGN Primitives according to the channel condition, the SATA transmission data errors can be reduced.

A substitute serial advanced technology attachment (SATA) host is provided to communicate with a SATA device for facilitating communication with the SATA device even when a status flag of the SATA device indicates that the SATA device is busy. The SATA host is thereby able to communicate with the SATA device even when the SATA device is not fully functional.
