Abstract

The invention discloses a method and device for processing cache synchronization abnormity. The method and the equipment are used for solving the problem that a processing scheme for compression checkfailure does not exist in the prior art. According to the embodiment of the invention, after the cache is asynchronous, the cache failure notification message is sent to the sending equipment, the compressed cache region is reset and the reset instruction is sent, and the reset-processed cache region is utilized to carry out subsequent data packet transmission. The method comprises the followingsteps of: determining that a cache is asynchronous; if so, sending a notification message of cache failure; the sending device carries out reset processing on the compressed cache region; According tothe method and the device, the receiving equipment is informed to perform decompression cache region resetting processing, and the cache region after resetting processing is utilized to perform subsequent data packet transmission, so that the problem of compression check failure in the prior art is solved, the UDC function is fully utilized, the air interface resource is saved, and the transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for processing cache synchronization exceptions. Background technique [0002] In LTE / LTE-A (Long Term Evolution, long-term evolution) / LTE-A (Long Term Evolution-Advanced, long-term evolution upgrade), the terminal can be configured with a UDC (UL data compression, uplink data compression) function. Uplink data compression means that the terminal compresses uplink data or signaling at Layer 2, and the base station side decompresses the compressed data at the corresponding protocol layer, in order to save the amount of data transmitted over the air interface, save uplink resources, and improve transmission efficiency. [0003] In order to improve the compression rate, the terminal and the base station maintain compression buffers independently according to the sent and received data. In general, two types of content can be stored in the compressed cache...
