Description

Real-time information exchange method and system

Technical field

The present invention relates to a kind of real-time information exchange method and system.

Background technology

Main real-time communication service market, the whole world mainly contains " the AIM Instant Messenger " of AOL at present, ICQ, " the MSN Messenger " of Microsoft, " the Yahoo Instant Messenger " of Yahoo, and in the China's Mainland very popular " QQ ", each is managed by different dealers, all adopt the exclusive private communications protocol that belongs to (proprietary), on function, do not have very big difference, and on market each have their own support person, but can only on identical realtime communication system, just can carry out communication between the confirmable user of being, can't intercommunication between the different system.Such influence causes the user when selecting realtime communication system, can not only terminate in individual's hobby and custom, and must consider other same friend who uses realtime communication system, household, colleague's etc. selection, therefore perhaps you have been noted that some people can install the above realtime communication system of many covers on same the computer, with convenient be scattered in the friend who uses different realtime communication systems everywhere and get in touch with.

The real-time communication service technology mainly comprises real-time message (instant messaging) and presence information (presence) technology.As can be known literal by " real-time message " and " presence information ", the main characteristic of real-time communication service is to know who is just online, then can transmit real-time message talks with it, or in whose just busy or meeting, you may just must select other communication way, for example transmit news in brief or Email etc.The another one characteristic is the transmission tool real-time of message, and being different from the past, message system (as Email, news in brief, multimedia message etc.) adopts the mechanism of transmitting then that stores earlier.

SIMPLE WG (SIP for Instant Messaging and Presence Leveraging ExtensionsWorkgroup,) be found in for the year ends 2000, selected SIP is the basic communications protocol of real-time message and presence information, discusses then and works out relevant SIP standard and extend.SIP is directed into real-time message and the presence information system is a very natural thing, this is because due to the nature of SIP.SIP is the communications protocol that IETF (InternetEngineering Task Force) formulates a kind of transmission signal (signal), mainly in order to consult, to manage and to stop media dialog stroke (media session), this kind media dialog stroke is to transmit communications protocol by specific data to finish, for example RTP (Real-time Transport Protocol).

Generally speaking, SIP is used for setting up voice call, but does not have the foundation that regulation SIP can only be used for voice call in the standard, and it does not rely on specific bottom medium, perhaps talks with the kind of stroke.Therefore when message also at last during a kind of medium, use SIP with regard to more naturally only.And SIP is in the world of network communication, the communications protocol that has been widely used at last, and it has possessed the function of registration (registration) and authentication (authentication).

Open session initial protocol (SIP) is a kind of standard agreement, by the extension protocol SIMPLE of SIP, though can realize communicating terminal between the exchange of real-time message, still can't realize the group chatting of real-time message.That is SIMPLE can't realize the real-time message exchange in the group.

Embodiment

Referring to Fig. 1, real-timemessage switching system 3 of the present invention comprisesserver 30,first member 32 and second member 34.First member 32 andsecond member 34 all are linked toserver 30, and registration onserver 30.

Before intrasystem communication switching begins, must set up interim group and add the member, just can carry out follow-up group member communication switching.Yet the foundation of interim group, member's adding and withdrawing from of member all have different flow processs.Following explanation will be divided into four blocks and describe its flow process respectively:

A, set up interim group;

B, adding member (inviting) by group master;

C, adding member (other main member of non-group invites);

D, member withdraw from interim group.

A, set up interim group:

The person of foundation is by inviting the member to add the mode of talks, setting up interim group.And the person of foundation uses " INVITE " request of session initial protocol to add a member who is present in good friend's inventory.After the person of foundation finished the program of inviting the member, interim group set up and finishes.The person of foundation is usually located at first cis-position of the member tabulation of this interim group, therefore be that the group of this interim group is main, and then the group is main adds fashionablely the invitation newcomer, have critical role.

Inviting second member with first member is example to form interim group, and good friend's inventory of first member comprises second member.

Referring to Fig. 2, need registrationfirst member 32 andsecond member 34 earlier on theserver 30, just can carry out subsequent step.At first, execution in step S10,first member 32 send invitation (INVITE) request of session initiation protocol (SIP), and the target of sending of this invitation request comprises second member 34.Then, execution in step S12,server 30 send target according to this and pass on this invitation request tosecond member 34.

Second member 34 receives this and invites request, and after finishing response, just can form an interim group with first member 32.Wherein, the member of this interim group tabulation comprisesfirst member 32 andsecond member 34, and this member's tabulation is stored infirst member 32 andsecond member 34 respectively.

B, adding member (inviting) by group master:

After interim group sets up, if the main desire of group is invited the newcomer, then initiate member needs to use in " INVITE " request and the interim group all members except the person of foundation to carry out media channel and bearing capacity is consulted, that is shake hands (handshaking).

Inviting the 3rd member with first member is example, and first member is that the group of interim group is main, and this good friend's inventory of first member comprises the 3rd member.

Referring to Fig. 3, execution in step S20 at first,first member 32 send first request of inviting and giveserver 30, and this first request of inviting comprises sends target and with reference to (X-referto) value, it is the3rd member 36 that first of this embodiment invites the target of sending of request, and reference point issecond member 34.

Then, execution in step S22,server 30 passes on this first invitation request to the3rd member 36 according to the target of sending of this first invitation request.

Then, after execution in step S24, the3rd member 36 receive this first invitation request, send second request of inviting according to this reference point and giveserver 30, and the target of sending of this second invitation request issecond member 34.

At last, execution in step S26,server 30 be according to this second target of sending of inviting request, passes on this second request of inviting to give thissecond member 34.

Second member 34 receives second and invites request, and after finishing response, the3rd member 36 has added this interim group, has also finished the program that the main newcomer of invitation of group adds.

C, adding member (other main member of non-group invites):

If other main member's desire of non-group invites the newcomer to add group in the group, the member's data that then need submit to desire to invite give the group main, must invite the newcomer by group master.After group master received submission information, invitation flow process afterwards was as the main flow process of inviting the newcomer of above-mentioned group.

Inviting the 3rd member to add group with second member's desire is example, and second member is not the group master of interim group, and this good friend's inventory of this second member comprises the 3rd member.

Referring to Fig. 4, at first, execution in step S30,second member 34 send one and submit to (REFER) request to giveserver 30, and this submission request comprises one and submits target to, and the submission target of this embodiment is the3rd member 36.

Then, execution in step S32 afterserver 30 receives and submits request to, must pass on this submission request to group main (first member 32).

Then, execution in step S34, group main (first member 32) submit target to according to this after receiving this submission request, andserver 30 is given in first request of inviting of sending.Wherein, this first invitation asks to comprise to send a target and a reference point.The target of sending of this first invitation request is the3rd member 36, and reference point issecond member 34.

Then, execution in step S36, server pass on this first invitation request to the3rd member 36 according to the target of sending of this first invitation request.

Then, execution in step S37 after this first invitation request of the3rd member 36 receptions, according to this reference point of this first invitation request, sends second invitation and asks to giveserver 30, and the target of sending of this second invitation request issecond member 34.

At last, execution in step S38,server 30 pass on this second invitation request tosecond member 34 according to the target of sending of this second invitation request.

Second member 34 receives second and invites request, and after finishing response, the3rd member 36 has added this interim group, has also finished the program that the main member of non-group invites the newcomer to add.

D, member withdraw from interim group:

If the member desires to withdraw from interim group, then need send one to leave and be notified to each remaining member in this interim group, allow other all members can upgrade own member's tabulation of being deposited.

Referring to Fig. 5, desiring to withdraw from this interim group with first member is that example describes.At first, execution in step S40, first of first member, 32 transmission SIP leave (BYE) and are notified to server 30.Wherein, this first target of sending of leaving notice issecond member 34.

Then, execution in step S42,server 30 be according to this first target of sending of leaving notice, and passes on that this first leaves and be notified tosecond member 34.

Then, execution in step S44, first member, 32 transmission second are left and are notified to server 30.Wherein, this second target of sending of leaving notice is the3rd member 36.

At last, execution in step S46,server 30 be according to this second target of sending of leaving notice, and passes on that this second leaves and be notified to the3rd member 36.

First leave notice and this second and leave notice whensecond member 34 and the3rd member 36 all receive this, and after finishing response,first member 32 finishes the program that withdraws from interim group.

What need remark additionally is that afterfirst member 32 withdrawed from group, ifsecond member 34 is second cis-position of member's tabulation of group, thensecond member 34 became the group master of this group.Ifsecond member 34 will withdraw from this group, similarly second member needs to pass on byserver 30 one the 3rd to leave notice (not illustrating) to the3rd member 36; After notice was left in the3rd member 36 receptions the 3rd,second member 34 finished the group's program that withdraws from.

So far, the present invention can reach the foundation of interim group based on SIP, has also reached member's interpolation and deletion, has therefore also just finished the necessary environment of group's communication switching.

Referring to Fig. 6, with the complete communication switching process real-time information exchange method that is elaborated.At first, execution in step S50,first member 32 send one first message and one second message simultaneously and give server 30.Owing to be group chatting, the chat content that each member receives is the same (being similar to broadcast message), therefore the chat content of first message and second message is identical, but the target of sending of first message is that the target of sending of second member, 34, the second messages is the3rd member 36.

Then, execution in step S52,server 30 are according to the target of sending of sending the target and second message of first message, and first message of passing on is givensecond member 34, and second message of passing on is given the 3rd member 36.Whensecond member 34 and the3rd member 36 respond respectively finish after, finished a communication switching of group chatting.

In addition, exchange the transmission of finishing message language by SIMPLE " MESSAGE " instruction between group member.The member of all supports " MESSAGE " instruction also can support pure words (plain text) form, CPIM (Common Presence and Instant Messaging) form or the message of HTML (HyperTextMarkup Language) form.Member in the group does not need to subscribe to group and learns group's state, can instruct resulting response according to " MESSAGE " because send message person, obtains the delivery status of message, and then obtains member's current state.If first member just at typing character, can notify other member current state about first member by " MESSAGE " instruction, for example: " first member typewrites ".
