METHOD, SYSTEM AND DEVICE FOR CONTEXT UPDATING, AND STORAGE MEDIUM

摘要

Disclosed in the embodiments of the present invention is a system for context updating, comprising a local end decompressor and an opposite end compressor. The local end decompressor is configured to send a second negative feedback to the opposite end compressor, when it is detected that a first negative feedback needs to be sent to the opposite end compressor and that the quantity of first decompressed context is greater than or equal to a configured first threshold. The opposite end compressor is configured to update, after receiving the second negative feedback, the first compressed context in the opposite end compressor, and send a data compressed packet carrying context update information to the local end decompressor. The local end decompressor is further configured to update the first compressed context using the context update information carried in the successfully decompressed data compressed packet, after the data compressed packet carrying the context update information, sent by the opposite end compressor, is successfully decompressed. Further disclosed in the embodiments of the present invention are a method and a device for updating context, and a storage medium.
