Background technology
Instant message is claimed instant messaging again, is meant through the instant communication service of sending and receiving message of means of communication such as the Internet.It has become one of main communication mode of people's daily life, work gradually since the eighties of last century birth nineties.From setting up new interpersonal relationships to increasing work efficiency, the instant message service all has huge help to people.
At present, the IM system of instant message service is provided,, all is based upon on client/server (C/S) the pattern basis like MSN, QQ etc.The service process of these IM systems is normally such: at first, the user imports the username and password login IM server of oneself, and the IM server comes identifying user identity through reading customer data base; If user name, password are all correct, just registered user's IP address, the version number of IM client software and the TCP/UDP port numbers of use are returned the user then and are logined successful sign; At this moment, the state of user in the IM system is online; Secondly; According to the buddy list of user storage on the IM server; The server relevant information that the user is online sends in simultaneously online good friend's the IM client software, and these information comprise the tcp port number that presence, IP address, IM client are used etc.; Good friend's IM client software receives that will eject a wicket after this information points out; Then, the IM client software that the IM server is transmitted back to him to buddy list and the relevant information of user storage on server, these information comprise the tcp port number that presence, IP address, IM client are used etc.After receiving, user's IM client software will show these buddy lists and presence thereof; Next; If the user wants the online good friend user's chat with him; He will utilize information such as good friend's user's IP address that server sends, tcp port number; Directly send information to good friend user's IM client software, be presented on the screen after good friend user's IM client software is received, good friend user directly is returned to user's IM client software more then.Like this, after both sides set up contact, instant message did not to each other just pass through the IM transit server, but directly carried out the peer-to-peer communications of point-to-point (P2P) through network.
In the service process of IM system, the IM server plays an important role.At first, the user need verify the legal identity of oneself through the IM server; Secondly, the user must and confirm online good friend through the searching of IM server, thereby sets up point-to-point peer-to-peer communications with online good friend.Therefore, the user is important with the unimpeded ten minutes of communicating by letter between the IM server.In a single day when for example being used to realize that the user belongs to the gateway disconnection of communicating by letter between local area network (LAN) and the exterior I M server, all can not use the instant messaging service in the local area network (LAN) and between the IM user outside the local area network (LAN) and between the IM user of local area network (LAN) inside.
The U.S. is green speeds (Green Packet), and communication scientific & technical corporation developed a kind of name is called SONbuddy
TMIntelligent radio networking software platform (specifically can referring to U.S. Patent application No.60/481,849).It can form a self-organizing network (SON) with any WIFI (802.11a/b/g) equipment, need not central server, dynamically forms point-to-point wireless network whenever and wherever possible.Utilize this software platform, can connect outside Internet, under the situation that does not have the IM server, realize the instant message function.Because the instant message service of using in the local area network (LAN) that this software platform provides can be avoided the infringement of virus, purifies Internet environment, and avoids the harassing and wrecking of flame.
But, from many-sided reasons such as use costs, network robustness, the instant message function that above-mentioned software platform is realized can't with the existing IM system that the instant message service is provided, be at war with like MSN, QQ etc.On the other hand, existing IM system can not connect Internet, for the user instant message service is provided in the absence of IM server.
