When the data packet is transmitted over the network, the receiving party distinguishes the voice or data according to the protocol code and then hands over to different modules of the receiving user end for processing. The voice data is processed by mixing the received data with the voice data of the receiving user end by the superposition technology and then transmitted to the adjacent user, so that the multi-party voice communication is realized. Moreover, the invention also provides a processing method for system user faults.
Description
The present invention is relevant for communication network technology, particularly relevant for the netmeeting that can realize that multipartite voice, literal and various formatted data transmit simultaneously.
Be accompanied by communication network and put the flourish of technology such as multimedia, make to be achieved for media transmits voice, literal and various formatted data by network (being systems such as Local Area Network or Internet for example).At present, the commercially produced product that can transmit multi-medium datas such as voice, literal by network has the Netmeeting of Microsoft company and the Internet Conference Professional of Vocaltec company etc., these products can utilize systems such as regional network or Internet to realize Multi-Party Conference, make the member who participates in a conference be obtained other members' Word message (chat) or graphic documentation (whiteboard).
Yet, the netmeeting of Microsoft company occupy conference moderator A will as collection for example meeting participant B, C, when D three carries out Web conference, the invite references person B of presider A elder generation participates in, between A and the B voice and data communication must be arranged, and " data " one language comprises Word message, graphic documentation or the extended formatting data of non-voice herein, so the voice data is lined up, but after C or D add Web conference between A and B again, have only data communication between C or D and A and the B, and do not have voice communication.In other words, have only between A and the B and enjoy voice communication, and only can carry out data communication between all the other users, and can't carry out voice communication, non-is the multipartite voice realization of Communication.
Moreover though the Internet Conference Professional that Vocaltec company produces has done a little improvement, so its action Netmeeting general and that Microsoft produces is similar.When the conference moderator A that adopts Internet ConferenceProfessional as rally view participant B, C, when D three carries out Web conference, conference moderator A one of has the right to select among meeting participant B, C, the D to carry out voice communication, but other meeting participants still can't hear conversation content therebetween, and also have only a side to talk simultaneously among the member of conference participation with conference moderator, the function of voice communication not between the meeting participant, thus also non-be the multipartite voice realization of Communication.
Comprehensively above-mentioned, commercially available Netmeeting and two products of Internet Conference Professional all have two common shortcomings at present:
(1) having only Web conference to participate in one of member can carry out voice communication with conference moderator, only communicates with data between other meeting participants, but can not carry out voice communication, and like this, system also fails really to realize the Web conference that multipartite voice is communicated by letter.
(2) if the conference moderator system breaks down, because of carrying out voice communications versus data communications simultaneously between all the other meeting participants, so Web conference is had to be forced to stop.
Therefore, main purpose of the present invention is to provide a kind of polytropic network communication system and fault handling method thereof, mode by the speech data simultaneous interpretation makes each member who participates in a conference all can speak simultaneously, and can hear other members' that participate in a conference sound, also can transmit simultaneously the data of Word message or extended formatting, realize the netmeeting of multipartite voice communication.
Other has a kind of Video Conference (video conference) agreement, proposes two kinds of connected modes: one are distributing multiple spot connection (decentralized multipoint connection); Another is that centralized multiple spot connects (centralizedmultipoint connection) structure.In distributing multiple spot syndeton, each user directly is connected with other users respectively, so when a certain user breaks down, do not influence the communication between other users; But distributing multiple spot syndeton requires quite high to the required disposal ability that possesses of all users in the system, moreover system also needs sizable frequency range.And centralized multiple spot syndeton adopts a multipoint control unit (multipoint control unit) to be connected with all users respectively, the carrying out that is conducted a meeting by multipoint control unit is so also have suitable requirement to the required disposal ability that possesses of multipoint control unit.
One object of the present invention is to provide a kind of polytropic network communication system and fault handling method thereof, makes meeting participant's number infinitely to expand.
Another object of the present invention is to provide a kind of polytropic network communication system and fault handling method thereof, and when arbitrary meeting participant broke down in system, the voice communications versus data communications between other meeting participants was unaffected.
A further object of the present invention is to provide a kind of polytropic network communication system and fault handling method thereof, and the required disposal ability that possesses of all users in the system is not had a lot of requirement, and system does not also need that frequency range is had too much requirement.
For reaching above-mentioned all projects, the present invention can be by a kind of polytropic network communication system is provided, in order to transmit speech data and data, this polytropic network communication system constitutes a network by a plurality of user sides, except that terminal temperature difference, everyone user is connected with two other user, and these terminal temperature differences only are connected with one of these users, each user comprises: network interface unit, in order to receive and to transmit these data; Processor is coupled to network interface unit, belongs to speech data or data in order to the data that identification received, if belong to speech data, then can give overlap-add procedure with the speech data of this user side self after, transmit once more in network through network interface unit again; If it is belong to data, prosperous through network interface unit transmission once more in network; Audio Processing Unit is coupled to processor, in order to receive user's self speech data, superposes in this processor, and handles the speech data that this user side receives; Display unit is coupled to this processor, and when the data that received when the processor identification belonged to data, this processor showed data on this display unit; And the data input unit, be coupled to this processor, for input this user's self data, on network, be sent to other users of network again through this processor and this network interface unit.
Moreover the present invention also can be applicable between first user and second user adjacent in this system by a kind of processing method of polytropic network communication system fault; This method comprises the following steps: that (a) second user continues regularly to send the detection data to first user; (b) judge that can second user receive this first user's response data at the appointed time, if then get back to step (a); (c) judge that whether first user also is connected with other users, if not, then sends the notice that first user has withdrawed to the user who still is connected with second user; (d) send the connection request order to the 3rd user who is connected with this first user, and obtain the 3rd user's agreement; And (e) connect second user and the 3rd user.
