Abstract: Disclosed in the present disclosure are a processing method and device for a cache synchronous exception, for solving the problem that no solution for a compression check failure is available in the prior art. According to embodiments of the present disclosure, when caches are out of synchronization, a caching failure notification message is sent to a transmitting device; a reset processing is carried out on a compressed cache area, and a reset instruction is sent; and then subsequent data packet transmission is carried out by using reset cache areas. In the present disclosure, after it is determined that the caches are out of synchronization, the caching failure notification message is sent; the transmitting device performs a reset processing on the compressed cache area, and notifies a receiving device to carry out a reset processing on a decompressed cache area.

Abstract: Provided are a method and device for performing data transmission capable of solving a problem in the prior art in which if a user equipment unit needs to perform transmission with a network, the user equipment unit needs to perform a cell switching process to enter another cell, and this results in higher signaling overheads for a terminal. In an embodiment of the invention, a new connected state is different from an idle state and a connected state. In the new connected state, a terminal can perform data transmission with a network side device. Moreover, after the terminal has moved to a coverage of another cell from a coverage of a cell currently accessed by it, the terminal can move to the new cell by means of cell reselection without performing a cell switching process.
