Instant communication system, instant communication client and instant communication method

Abstract

The invention discloses an instant messaging system, an instant messaging client and an instant messaging method. The instant messaging method includes the following steps: a second instant messaging client generates an instant message containing receiving confirmation information for an off-line message and sends the instant message to a first instant messaging client after receiving the off-line message from the first instant messaging client. As an off-line contact feeds the receiving confirmation information for the off-line message back to a sender of the off-line message after receiving and checking the off-line message, the instant messaging user sending the off-line message is allowed to have an idea whether the off-line message sent by the instant messaging user is already checked and received by the contact, thus facilitating communication between the instant messaging user and the off-line instant messaging user and greatly enhancing easy use of an instant messaging software and communication effectiveness among the instant messaging users.

Description

technical field [0001] The invention relates to instant messaging (IM, Instant Messaging) technology, in particular to an IM system, an IM client and a communication method based on the IM system. Background technique [0002] With the rapid development of IM technology, IM software has become one of the indispensable communication tools for network users. [0003] At present, the IM software used by network users can basically support real-time message communication between two IM users, that is, information interaction and communication between two online IM users can be performed through instant messages. In some special cases, if one of the IM users is offline, another IM user can also send an offline message to the offline IM user through the IM software. This kind of offline message needs to use the IM server as an intermediary device to cache and manage the message, and then when the offline IM user goes online again, the IM server downloads the message according to ...

Problems solved by technology

However, at this stage, the sender of the offline message is ignorant of whether the receiver of the offline message receives or views the offline message, that is, the IM user does not know whether the receiver of the offline message is The offline message has been checked and received. Therefore, there may be a communication blind spot between two IM users in this non-real-time message communication. If the online time of the two people is staggered, effective communication cannot be realized.
