Embodiment
Below in conjunction with accompanying drawing principle of the present invention and feature are described, institute gives an actual example and only is used to explain the present invention, and is not used in the scope of the present invention that limits.
Use group system network frame of the present invention as shown in Figure 1, it comprises logic function modules such as colony terminal 100, base station sub-system BSS (BASE STATION SUBSYTEM) 110 and dispatching service system DSS (DispatchingService System) 120.
Wherein, colony terminal 100 links to each other with base station sub-system BSS by air interface, and the miscellaneous service for the user provides group system also provides traditional plain old telephone service, short message service and data service for the user simultaneously.
Base station sub-system BSS mainly finishes the wireless access function of various group services, data service and plain old telephone service, is made of base station transceiver BTS (Base Transceiver System) 111, base station controller BSC (Base Station Controller) 112 and dispatching client PDC (PTTDispatching Client) 113.Wherein radio receiving-transmitting unit BTS finishes the function such as modulation and demodulation, radiofrequency signal transmitting-receiving of baseband signal, base station controller BSC is finished all kinds of switchings of wireless resource allocation, call treatment, power control and support terminal, and dispatching client PDC then finishes wireless resource allocation, dispatch call control, power control, supports all kinds of switchings under the different areas of coverage of colony terminal, compiles and distribute the cluster audio data stream.
Dispatching service system DSS120 mainly finishes colony dispatching service, is made up of dispatch server 121, authentication server 122, accounting server 123, scheduling proxy server 124.
Wherein dispatch server 121 is master control points of trunked call, finishes the processing of colony dispatching calling, comprises the discriminating cluster user, sets up various trunked calls such as individual calling and group call, judgement cluster PTT request etc.Dispatch server 121 can also receive the cluster speech data of reverse link, is distributed to corresponding forward link again according to the character of calling out.
Scheduling proxy server 124 is entities of finishing the dispatching desk function in the group system, and the dispatching desk client at dispatcher place can be carried out various scheduling actions by it, such as dispatcher's call group etc.Scheduling proxy server 124 and dispatch server 121 have the Signalling exchange passage, and scheduling proxy server 124 can also directly carry out some operation to the database in the authentication server 122.
In the group system as shown in Figure 1, dispatch server 121 has all ongoing trunked calls (containing individual calling, group calling) information in the group system, comprises that all are rising to exhale, or calling out, or just in the calling that is in various call states of call release.
As Fig. 2, in the prior art, when the user initiates group calling, dispatch server 121 can send group calling authentication request message (step 201) to authentication server 122,122 pairs of calling and called of authentication server carry out authentication, and obtain all group membership's information, and authentication server 122 sends group calling authentication response message (step 202) to dispatch server 121 then, contain the information of calling and called and group membership's summary info in the message, as number of group membership etc.In this authentication process, when the number of group member a lot, if any several thousand the time, authentication server 122 will spend the long time (generally spending more at least more than the expense hundreds of millisecond) and carry out authentication process, in during this period of time, all members of group contain caller and are waiting for, dispatch server 121 also in wait, adds the time that group calling is conversed thereby prolonged group member greatly.In view of the paging mode of bigger group is to carry out paging according to group identification, 121 need of dispatch server know that the sign of group just can carry out paging to all terminals in the group, in case the paging success, group membership's terminal just can be carried out group calling.The present invention proposes following group calling authentication method for this reason, can improve the group calling launch speed greatly.
Below be the first embodiment of the present invention:
The first embodiment of the present invention is mainly sent the group calling request by the terminal use and is realized that as shown in Figure 3, it may further comprise the steps:
Step 301: trunking terminal user is dialed group number and is initiated group calling, and this request arrives dispatch server through base station sub-system.
Step 302: dispatch server takes out the attribute of colony terminal in the above-mentioned request message of receiving, takes out simultaneously and this time calls out the attributes such as sets of numbers of called group, is processed into the message of group calling authentication request then, and sends to authentication server.
Step 303: the content in the message that authentication server receives and the resolution scheduling server is sent, then calling and called are carried out authentication, judge promptly whether this colony terminal is legal, whether the authority of initiating this group group calling is arranged, whether whether called group exists, legal, if terminal is illegal or do not initiate the authority of this group group calling, or group does not exist or group is illegal, and execution in step 308 so; Otherwise execution in step 304.
Step 304: authentication server is according to receiving that the information of calling and called in the message inquires calling subscriber's the user profile and the group id of group from database, information such as group service area, obtain the call priority value of group calling simultaneously, the group calling authentication response message that authentication server will carry above-mentioned taking-up information sends to dispatch server.
Step 305: dispatch server receives and resolves described group calling authentication response message, checks according to group identification whether this group has been in call state, if be in call state, execution in step 306 so, otherwise execution in step 307.
To the judgement of this call state promptly is to judge that this time calling out is that new calling of initiating or user lag to add and call out.This group end is in call state, and representing this is a new calling, is in call state, represents this master to exhale the user to lag.
Step 306: lagging for the user adds the situation of group call, and dispatch server is directly by the base station subsystem paging caller, caller is added call out, and the caller state is changed in the calling.Simultaneously, authentication server can also pass through dispatch server, and base station sub-system sends the adding group calling to terminal and successfully indicates.This time authentication finishes.
Step 307: for situation about newly making a call, dispatch server is sent out paging according to the service area and the group identification of group by base station sub-system each member in group; Dispatch server carries out obtaining the information of all group members alternately with authentication server simultaneously.This time the group calling authentication flow process finishes.
Step 308: authentication server is by dispatch server, and base station sub-system sends the failed authentication reason to terminal.This time the group calling authentication flow process finishes.
In step 307, dispatch server carries out paging to the member in the group, in case more than one called member and the paged success of caller are arranged, the group calling passage is just set up so, just can have been carried out speech exchange between the user of incoming call.Dispatch server can send to calling terminal and exhale successfully notice.The information that follow-up dispatch server obtains group member is in order better to control the state of each group member, to be convenient to launch every supplementary service.
Because dispatch server uses group identification that the group membership is carried out paging, the sign of group under must existing on group membership's terminal, this is to be undertaken by group information updating, and group information updating can make the information that has all affiliated groups of terminal on the terminal, comprises group identification etc.The method of group information updating can be with reference to other patent and technology.
Wherein dispatch server carries out alternately with authentication server in the step 307, and the process that obtains the information of all group members further comprises following steps:
Step 1: the information structuring group member summary info request messages such as group identification of dispatch server in the group calling authentication response message of receiving, and send to authentication server;
Step 2: authentication server receives the also group member summary info request message of resolution scheduling server, from database, obtain the summary info of group member by group identification, such as the group member number, etc. information, obtaining each dispatch server simultaneously can be to greatest member's number of authentication server request, authentication server is processed these information, sends group member summary info response message to dispatch server;
Step 3: dispatch server receives and resolves the group member summary info response message of authentication server, and dispatch server sends one or more group member information request messages according to group member number and the number that can ask at every turn to authentication server;
Step 4: authentication server receives and resolves the group member information request message that this dispatch server is sent, and the information of the group member of each request message correspondence is processed into the group member information answer message of group member information request message correspondence, be sent to dispatch server.
Step 5: dispatch server sends the information about firms end notification message to authentication server after obtaining the information of all group members by request information about firms message.
Step 6: behind member's end notification message that authentication server receives and the resolution scheduling server is sent, the mode that obtains group member according to concrete dispatch server is carried out corresponding cleanup action, and the back sends information about firms end notification response message to dispatch server.
In the step 3 of appeal, the individual number calculating method of the group member information request message that dispatch server sends is: the group member sum removes the merchant of the group member number that at every turn can ask, if remainder is arranged, then adds 1 again.
At this above-mentioned user is lagged to call out and describe.The user is one of group membership of group, but because some reason (rise when exhaling such as group, the user is in other ongoing group calling), the user has missed ongoing group calling.The user can also lag in the group number adding group calling of dialing group.Because authentication server can not be judged the user and lag and add to call out or the initiation group calling when receiving group calling authentication message, so the still group calling authentication that carries out of authentication server.Will be still in the prior art when carrying out authentication the time more than the cost hundreds of millisecond go to obtain the information of all group members in the group, but in fact the user lag add to call out be with other groups in the member it doesn't matter, so the processing mode of prior art makes the part resource by unnecessary waste.According to the embodiment of the invention, there has been very big shortening the time of initiating the described first step group calling authentication of group calling as the front, and the time that the user adds calling has also obtained great shortening, and has prevented the waste of resource effectively.
Below describe the flow process of the interacting message of first embodiment of the invention in detail by Fig. 4.
Step 401: terminal is initiated the group calling request, by base station sub-system, dispatch server, arrives authentication server;
Step 402: authentication server carries out authentication to promoter and called group, and after obtaining call priority, tells dispatch server by response message;
Step 403: the dispatch server inspection lags to add and calls out or the initiation group call, carries out respective handling;
Step 404: dispatch server will be replied by base station sub-system and be issued terminal and indicate current progress;
Step 405: the dispatch server structure also sends group member summary info request message to authentication server;
Step 406: authentication server sends group member summary info response message to dispatch server;
Step 407: dispatch server sends the group member information request message to authentication server;
Step 408: authentication server sends group member information answer message to dispatch server;
Number according to the number of group member and the member that can obtain at every turn, it is how right that group member information request message and corresponding response message have, how right be that step 407 and 408 has, these all group member information request response messages can walk abreast, and do not need sequencing.
Step 409: dispatch server sends information about firms end notification request message to authentication server;
Step 410: authentication server sends information about firms end notification response message to dispatch server;
Below be the second embodiment of the present invention:
Second embodiment of the invention is sent the group calling request by the dispatcher and is realized, may further comprise the steps:
Steps A when dispatcher's (according to dispatching requirement) needs to call out a group, by the group call menu of scheduling proxy server, is sent the request of group calling, and this request arrives dispatch server through scheduling proxy server;
Step B: dispatch server is according to the information structuring group calling authentication request message of dispatcher's caller in the request message and called group, and sends to authentication server;
Step C: authentication server takes out the content in the above-mentioned request message of receiving, obtain the number of caller dispatcher's information and called group, judge then whether the dispatcher is legal, whether the authority of initiating this group group calling is arranged, whether whether called group exists, legal, if the dispatcher is illegal or do not initiate the authority of this group group calling, or group does not exist or group is illegal, so execution in step H; Otherwise execution in step D;
Step D: authentication server is according to receiving that the information of calling and called in the message inquires caller dispatcher's the information and the group id of group from database, information such as group service area, obtain the call priority value of group calling simultaneously, authentication server will carry these group calling authentication response messages of taking out information and send to dispatch server;
Step e: dispatch server receives and resolves the response message of authentication server, checks according to group identification whether this group has been in call state, if be in call state, and execution in step F, otherwise execution in step G;
Step F: dispatch server and dispatcher place dispatching client are set up the Media Stream passage by scheduling proxy server, and the dispatcher just adds group calling and can make a speech, and dispatch server is changed to dispatcher's state in the conversation, and this time authentication finishes;
Step G: dispatch server is sent out paging according to the service area and the group identification of group by base station sub-system each member in group, dispatch server and dispatcher place dispatching client are set up the Media Stream passage by scheduling proxy server simultaneously, and dispatch server obtains the information of all group members alternately with authentication server simultaneously.This time group calling authentication finishes.
Step H: authentication server is by dispatch server, and scheduling proxy server sends the failed authentication reason to the dispatching client at dispatcher place.This time the group calling authentication flow process finishes.
Wherein dispatch server carries out alternately with authentication server among the step G, and the process that obtains the information of all group members further comprises following steps:
Step G1: the information structuring group member summary info request messages such as group identification of dispatch server from group's authentication responses message of receiving, and send to authentication server;
Step G2: authentication server receives the also group member summary info request message of resolution scheduling server, from database, obtain the summary info of group member by group identification, such as information such as group member numbers, obtaining each dispatch server simultaneously can be to greatest member's number of authentication server request, authentication server is processed these information, sends group member summary info response message to dispatch server;
Step G3: dispatch server receives and resolves the group member summary info response message of authentication server, and dispatch server sends one or more group member information request messages according to group member number and the number that can ask at every turn to authentication server;
Step G4: the group member information request message that authentication server receives and the resolution scheduling server is sent, and the information of the group member of each request message correspondence is constituted the group member information answer message of request information about firms correspondence.
Step G5: after dispatch server obtains the information of all group members by the group member information request message, send the information about firms end notification message to authentication server.
Step G6: behind member's end notification message that authentication server receives and the resolution scheduling server is sent, the mode that obtains group member according to concrete dispatch server is carried out corresponding cleanup action, and the back sends information about firms end notification response message to dispatch server.
In the step G3 of appeal, the individual number calculating method of the group member information request message that dispatch server sends is: the group member sum removes the merchant of the group member number that at every turn can ask, if remainder is arranged, then adds 1 again.
According to the embodiment of the invention, in the group calling authentication process, all group memberships are paged with regard to having begun after first step authentication responses, and can call out when group calling subsequent requests group member authentication is carried out.And authentication server does not relate to the relevant treatment of numerous group members in the group in first step group calling authentication is handled, compare with existing group calling authentication mode, under the more situation of group member number, the processing time has great shortening (generally can improve more than the speed hundreds of millisecond).Guaranteed that to heavens user's high-quality is experienced in the group system.
