Description
technical field [0001] The invention relates to the technical field of instant messaging, in particular to a method and device for receiving offline data, a method and device for sending offline data, and a system for transmitting offline data. Background technique [0002] Currently, an IM (Instant Messaging, instant messaging) technology has been widely used. It can provide a series of online processing functions of instant information such as real-time message sending and receiving, status display, voice / video, file transfer, file sharing and remote assistance. Group is a very important application in IM technology, mainly used for multi-person chat. In multi-person chat, the group server acts as a message relay, and it carries massive amounts of data all the time, including text messages, pictures, files, and so on. For text messages, because the amount of data is not large, it is usually cached in the server, and can be stored for a long time. When the user goes onlin...
