Summary of the invention
Technical problem to be solved by this invention provides a kind of method that realizes conferencing function in the scheduler subsystem of wireless clustered system, so that each terminal can be initiatively or the passive conferencing function entity that is linked in the scheduler subsystem, in many ways carrying out full duplex converses in real time, make the discussion of can collective conversing of each terminal use and dispatching desk user, and carry out withdrawing from according to circumstances in the process and again adding in meeting.For this reason, the present invention is by the following technical solutions:
It has following steps before meeting begins:
1-a), dispatching desk arranges the step of conference member table, described conference member tabular has conference member, described conference member comprises dispatching desk and all colony terminals that participate in a conference; In the conference member table, each conference member has following binomial data: the identification number of conference member, state, it is off-line state when the state of described conference member is initial, be in and be talking state in the meeting, described conference member table is the conference member table that dynamically arranges, and carries out in the process increasing newly or withdrawing from along with conference member in meeting, the conference member table is correspondingly on-the-fly modified
1-b), the conferencing function entity sends invitation according to conference member table listed colony terminal in the described conference member table;
Described method carries out having following steps in the process in meeting:
2-a), other colony terminal applications outside the accessing conference add the step of the request of meeting, described request is sent to dispatching desk by the identification number of call scheduling platform, and whether dispatching desk determines to admit this terminal to enter the step of meeting, as admitting, corresponding modify conference member table
2-b), dispatching desk is according to instruction, the colony terminal outside meeting sends the invitation that adds meeting, and revises the conference member table,
2-c), need to leave meeting such as the conference member that is in the meeting, the colony terminal of described conference member disconnects the step of conversation, leaves in this way meeting, and the conference member table is corresponding to be modified,
2-d), dispatching desk is according to instruction, evicts certain conference member the step of meeting from, and corresponding modify conference member table,
The talking mode that described method is carried out in the process in meeting comprises single worker's conversation and duplex conversation, and described talking mode is selected to switch by dispatching desk; When single worker conversed, the spokesman can be dispatching desk, also can be certain colony terminal by the dispatching desk appointment, during the duplex conversation, mailing to the conference voice of each conference terminal, is the member condition according to the conference member table, is synthesized by the voice of other conference members.
Described conferencing function entity refers in the scheduler subsystem of wireless clustered system to realize one of the conferencing function more subsystem of next stage, for explaining conveniently, this secondary subsystem is called the conferencing function entity.
Because adopt technical scheme of the present invention, conferencing function of the present invention is realized in wireless colony scheduler subsystem.Other entities in the wireless clustered system need not to do any change such as the software and hardware of the equipment such as switching center, base station, terminal.Compared with prior art, the present invention is with joining meeting to terminal and leave the method for meeting, be adjusted to that dispatching desk is invited and by from, terminal is initiatively applied for and this dual mode of dialysis initiatively, so that the organizational form of meeting has obtained is abundant and perfect.Conference member can interrupt meeting temporarily, carries out coming back in the meeting after the important calling; Non-conference member can provisional application add meeting; Meeting carry out middle according to content of the discussions can be temporarily by from the member who is not suitable for participating in, wait content of the discussions again it to be re-invited after changing and enter.
Aspect the processing of conference voice, introduced duplexing call mode.The starting point of holding a meeting is exactly to satisfy the demand that many people discuss discussion for a long time, and the pattern of duplex conversation has obviously satisfied the needed high efficiency of brainstorming better.When great item notice or important speech, meeting still can switch to single worker's call mode.
So that in whole conference process, ensured the orderly and efficient of meeting, improved the effect of the discussion subject under discussion of meeting.
In said method, realize the device of conferencing function, mainly consisted of by conference organisations' module, this two large module of conference voice processing module.
Conference organisations' module: the session connection of being in charge of the leaving of the entering of conference member, conference member, conference member is safeguarded.Abide by the signaling interaction method in connection that group system calls out, disconnection, the maintenance process, realize entering, leaving with session connection and safeguard of conference member.
The conference voice processing module: according to the conference speech pattern, the conference voice processing module is responsible for voice are processed.The conference speech pattern is divided three classes: host's pattern of making a speech, specify conference member speech pattern, collective's speech pattern.
Host's pattern of making a speech: single worker's call mode.Under this pattern, the conference voice processing module sends to each conference member terminal with the voice of dispatching desk.
Specify conference member speech pattern: single worker's call mode.Under this pattern, the conference voice processing module sends to each conference member terminal with the voice of the conference member of the selected appointment of dispatching desk.
Collective's speech pattern: duplexing call mode.Under this pattern, the conference voice processing module is synthesized processing with the voice of each conference member, and each synthetic conference voice sent to each conference member terminal, mail to the conference voice of each conference terminal, be the member condition according to the conference member table, synthesized by the voice of other conference members.Specifically, when A, B, C three people join conference system, hold a meeting, then after synthetic, send C AB two people's voice, after synthetic, send A BC two people's voice, after synthetic, send B AC two people's voice.The situation that N people participates in meeting that is to say by that analogy, and the voice that each conference member is received all are synthesizing except own other all conference member voice.In the process of synthetic speech, the volume weight of each member terminal voice can be adjusted by dispatching desk, is used for increasing the weight of in synthetic speech or weakening the speech volume of some member terminal.
Under various speech patterns, dispatching desk all can be with other source of sound accessing conference systems outside the meeting member speech, are sent to each terminal with after itself and other phonetic syntheses.This function is undertaken by the conference voice processing module.

Embodiment
With reference to accompanying drawing 1.The formation of wireless cluster communication system comprises terminal 101, base station 102, switching center 103, nms subsystem 104 and scheduler subsystem 105.
The below is described in detail the meeting implementation method, as shown in Figure 2.
As the host of meeting, dispatching desk is born initiating conference, managerial meeting member, is selected the responsibility of conference voice pattern and closing session.For this reason, two identify label numbers of dispatching desk registration outside the basic service number, also will be registered a conference number as meeting identification number.The basic service number, the basic service that is used for dispatching desk is processed, such as group calling, individual calling etc.; Conference number acts on convention business specially.In conference process, the conference number that the terminal of non-conference member can the call scheduling platform is applied for joining in the ongoing meeting.
At first, dispatching desk is set up the conference member table, initiates a meeting (201).Dispatching desk arranges a conference member table before meeting begins, comprised the dispatching desk of initiating conference and all colony terminals that participate in a conference.Each conference member has following binomial data: the identification number of conference member, state.Be off-line state when the state of conference member is initial, being in the meeting is talking state.Wherein, the meeting identification of dispatching desk number is its conference number, but not the basic service number; The identification number of each terminal is its basic service number.This form dynamically arranges in the conferencing function entity of scheduler subsystem, has comprised current all conference members that participate in a conference.Meeting is carried out in the process, and along with the newly-increased of conference member or withdraw from, the conference member table correspondingly on-the-fly modifies, and this modification is undertaken by conference organisations' module.
The conferencing function entity passes through switching center and invites each conference terminal to add meeting (202).The conferencing function entity sends invitation by switching center to each conference terminal according to the conference member table.
Each joining meeting to terminal (203).The terminal that receives invitation is the accessing conference functional entity separately.
Select speech pattern (204) by dispatching desk in the conference process.Meeting begins, and dispatching desk can elect in three kinds of speech patterns, and can switch as required.For instance, can be with host's pattern of making a speech, explanation conference background and notice item when meeting has just begun; Then switching enters collective's speech pattern, and for everybody colloquy, dispatching desk can be regulated speech components in the discussion process, the wherein voice of a part of terminal of giving prominence to the key points; If necessary, dispatching desk can switch to mandatory member's pattern of making a speech, and allows all conference members listen to simultaneously the individual speech of certain terminal; The mandatory member makes a speech complete, and dispatching desk can switch to collective's speech pattern again, recovers to discuss.In whole conference process, the conference voice processing module is come synthetic speech according to each member condition in the conference member table.
Dispatching desk invites other-end to add meeting (205) temporarily in the conference process.Meeting is carried out in the process, participates in a conference if find the terminal that also should invite certain not participate in a conference, and dispatching desk can be initiated the invitation to this terminal at any time, conference member table corresponding modify.
Other non-conference terminal call scheduling platform conference numbers in the conference process, application adds meeting (206).Meeting is carried out in the process, if the terminal that does not participate in a conference is arranged, namely excludes the terminal of conference member table, and hope can join in the meeting, and this terminal can apply for adding with the conference number of call scheduling platform.
Dispatching desk verifies that this terminal could accessing conference (207).Whether dispatching desk can be judged according to applicant's basic service number applicant's identity after the adding meeting application of receiving other-end, determine to allow it to add meeting.If agree, the joining meeting to terminal of filing an application (208), this terminal is linked in the meeting, conference member table corresponding modify; If dispatching desk is refused its application, the terminal of filing an application can not add meeting (209).
The conference member terminal initiatively withdraws from meeting (210) in the conference process.Meeting is carried out in the process, if certain terminal that participates in a conference has other business to need to process, can disconnect conversation, withdraws from meeting, conference member table corresponding modify.After if other business is disposed, this terminal still wishes to return meeting, and the method (206) that can add meeting according to the aforementioned application again conference number of call scheduling platform is applied for.
Dispatching desk evicts out of meeting (211) with the hoc meeting member terminal in the conference process.Meeting is carried out in the process, if dispatching desk thinks that certain terminal has been not suitable for discussing current conference content, can cut off this terminal and be connected with conversation between the meeting functional entity, evicts it from meeting, conference member table corresponding modify.
The dispatching desk closing session, each conference member terminal withdraws from meeting (212).When meeting adjourned, dispatching desk cut out meeting.Not yet initiatively leave each terminal of meeting, be connected and can be cut off with conversation between the meeting functional entity, all conference members leave meeting, and all members return to off-line state in the conference member table.
In the whole conference process, the Signalling exchange flow process between each entity, specifically describe as follows:
The conferencing function entity sends invitation to terminal, makes its step that enters meeting as shown in Figure 3.Behind the dispatching desk initiating conference, the request of sending of conferencing function entity connects signaling to switching center 301; Switching center sends to terminal and asks to connect signaling (302); Terminal is sent response signaling (303) to switching center after receiving the signaling of asking to connect, and enters the response state, the terminal ring; Behind terminal use's off-hook, terminal is sent to switching center and is connected signaling (304); Switching center sends out to the conferencing function entity and connects signaling (305); The conferencing function entity is set up a voice channel (306) after receiving and connecting signaling between conferencing function entity and conference terminal, the state of counterpart terminal member in the conference member table is set to talking state.After voice channel was set up, the conference voice processing module transmitted voice according to the conference speech pattern to this terminal.
Terminal is initiatively sent signaling, and the step that application enters meeting as shown in Figure 4.The call number of non-conference terminal call scheduling platform, the request of sending connects signaling to switching center 401; Switching center sends to the conferencing function entity and asks to connect signaling (402); The conferencing function entity determines whether agreeing this terminal access (403) by dispatching desk after receiving the signaling of asking to connect.If dispatching desk refusal, conferencing function entity send refusal to switching center and connect signaling (4040), switching center sends refusal to this terminal and connects signaling (4041), and application is rejected, and procedure to apply finishes; If dispatching desk allows this terminal access, then the conferencing function entity sends to switching center and agrees to connect signaling (4050).Switching center is connected with the conferencing function entity to terminal and connects signaling (4051) thereupon; Between conferencing function entity and conference terminal, set up a voice channel (4052), this terminal member who increases newly in the conference member table is set to talking state.After voice channel was set up, the conference voice processing module was passed on voice according to the conference speech pattern to this terminal.
Terminal is sent signaling, initiatively leaves the step of meeting as shown in Figure 5.Terminal initiatively discharges the voice channel (501) between conferencing function entity and the conference terminal, sends to disconnect signaling to switching center (502); Switching center sends release connection signaling (503) to terminal, sends to the conferencing function entity and disconnects signaling (504); After the conferencing function entity is received and disconnected signaling, send out release connection signaling (505) to switching center, and the state of counterpart terminal member in the conference member table is set to off-line state.
The conferencing function entity sends signaling to terminal, away from the step of meeting as shown in Figure 6.The conferencing function entity discharges the voice channel (601) between conferencing function entity and the conference terminal, sends and disconnects signaling to switching center 602; Switching center sends to calling terminal and disconnects signaling (603), sends release connection signaling (604) to the conferencing function entity; After the conferencing function entity is received release signaling, the state of counterpart terminal member in the conference member table is set to off-line state.
In order to reach better fail safe, before initiating conference, can guarantee with an authentication process authority of dispatching desk user.Authorizing procedure as shown in Figure 7.When the user logins into scheduler subsystem 701 by dispatching desk, need to confirm its authority at login interface input scheduling person's account and password (702).Scheduler subsystem obtains corresponding account and password (703) from the network management data storehouse, then come comparison both sides account number cipher to confirm user right (704) with algorithm.Eligible users has the authority (705) of using dispatching desk to hold a meeting; Defective user does not then enjoy authority (706).
Above-mentioned embodiment is not the further restriction to technical solution of the present invention, and is within the spirit and principles in the present invention all, and being equal to of the technology of the present invention feature replaced or corresponding improvement, still is within protection scope of the present invention.
