Problems solved by technology

[0007] Since the superframe number is similar to the carry number of the packet sequence number, when the packet is lost or Out-of-sequence Delivery (Out-of-sequence Delivery) or a protocol error occurs in the system, the superframe number may be wrongly accumulated, resulting in the superframe number between the receiving end and the transmitting end. Frame numbers are out of sync, causing decryption errors
When the decryption is wrong, the result of header decompression will also be wrong and fail to pass the Cyclic Redundancy Check (CRC) check, thus causing the packet to be deleted
However, the known technology does not clearly define how to detect and repair the superframe number out-of-sync error in the long-term evolution wireless communication system, which affects the transmission efficiency

Embodiment Construction

[0037] Please refer to FIG. 2 . FIG. 2 is a functional block diagram of a wireless communication device 100 in a wireless communication system. The wireless communication system is preferably a LTE wireless communication system. For simplicity, FIG. 2 only shows an input device 102 , an output device 104 , a control circuit 106 , a CPU 108 , a storage device 110 , a program code 112 and a transceiver 114 of the wireless communication device 100 . In the wireless communication device 100, the control circuit 106 executes the program code 112 stored in the storage device 110 through the central processing unit 108, thereby controlling the operation of the wireless communication device 100, which can receive user input through the input device 102 (such as a keyboard) signal, or output signals such as picture and sound through the output device 104 (such as a screen, a speaker, etc.). The transceiver 114 is used for receiving or sending wireless signals, and transmitting the rece...

Abstract

A method for recovering a protocol error in a receiver of a wireless communications system includes receiving a packet including a compressed and ciphered header, performing a deciphering procedure on the header according to at least a deciphering parameter to get a deciphered result, performing a decompression procedure on the deciphered result according to a decompression algorithm to get a decompression result, performing a check procedure on the decompression result to determine whether the deciphering parameter is correct, and recovering the protocol error when a result of the check procedure indicates that the deciphering parameter is not correct.

Description

technical field [0001] The present invention refers to a method for repairing protocol errors in a wireless communication system and related devices, especially to a method and related devices that can timely repair errors in decryption parameters, avoid unnecessary deletion of packets, and effectively improve transmission efficiency. Background technique [0002] The third-generation mobile communication technology can provide high spectrum utilization efficiency, unlimited coverage, high-quality, high-speed multimedia data transmission, and can meet various QoS service requirements at the same time, providing flexible and diversified Two-way transmission service, and provide better communication quality, effectively reduce communication interruption rate. However, the industry has begun to develop the next generation of mobile communication technology due to the high demand for high-speed data transmission and multimedia applications in the market, and the relevant specifi...
