Embodiment
The present invention adopts the identical networking structure of prior art trunked communication system to realize monitoring to group calling.Its concrete monitor method comprises: set monitoring group corresponding virtual in advance and monitor number in cluster server and moving exchanging center MSC, when dispatching desk is attended a banquet request monitoring, carry out the following step:
Dispatching desk is attended a banquet and is initiated monitored call to the dispatching desk gateway, carries and monitors flag information and monitor group id ID;
The dispatching desk gateway is attended a banquet to dispatching desk by cluster server and is carried out authentication, and obtains the corresponding virtual monitoring number that cluster server returns;
The dispatching desk gateway carries the virtual monitoring number of acquisition and initiates interception request to moving exchanging center MSC;
MSC judges that virtual monitoring number is to allow described dispatching desk to attend a banquet behind the dispatcher of monitoring group ID correspondence to monitor.
Below in conjunction with accompanying drawing, said method of the present invention is described in detail.
Referring to Fig. 2, be the inventive method flow chart, comprise following concrete steps:
Step 1, the trunked call register of MSC (Group Call Register, GCR) in, memory scheduling person's tabulation; Each monitoring group corresponding virtual of storage is monitored number as its dispatcher in dispatcher's tabulation; As shown in table 1 below:
Table 1:
| Monitoring group ID | The corresponding virtual monitoring number that is provided with |
| Monitoring group 1 | 1、A |
| Monitoring group 2 | 2 |
| ...... | ...... |
| Monitoring group N | E、A |
In the last table 1, expression has several monitoring groups, and the group ID of its correspondence is respectively " 1 ", " 2 " ... and " N ".Each monitoring group is provided with corresponding virtual and monitors number, for example:
It is " 1 " and " A " that monitoring group " 1 " corresponding virtual is monitored number;
It is " 2 " that monitoring group " 2 " corresponding virtual is monitored number;
It is " E " and " A " that monitoring group " N " corresponding virtual is monitored number.
As can be seen from Table 1, can comprise one or more corresponding virtual in the dispatcher of each the monitoring group tabulation and monitor number; And can comprise identical or different virtual monitoring number in the dispatcher of the different monitoring groups tabulation.As a kind of special case, all monitoring groups also can all be provided with same unique monitoring number.
Virtual monitoring number is not the true number that monitoring users place dispatching desk is attended a banquet, and the true number that monitoring users place dispatching desk is attended a banquet and the group ID of monitoring can uniquely determine a virtual monitoring number.That is: a virtual monitoring number in monitoring group can be corresponding with a plurality of monitoring users (being the true number that the dispatching desk at monitoring users place is attended a banquet); And monitoring users is owing to monitor different monitoring groups, also can corresponding a plurality of virtual monitoring numbers.
Step 2, the dispatching desk registration monitoring right of attending a banquet; That is: dispatching desk is attended a banquet and is initiated register requirement to cluster server, carries self true number, monitoring group ID.For example:
If the user wants monitoring group " 1 ", then attend a banquet and initiate register requirement to cluster server by dispatching desk, carry true number (being assumed to be " 001 ") and monitoring group ID " 1 " that this dispatching desk is attended a banquet.
After step 3, cluster server are received register requirement, attend a banquet for this dispatching desk and to distribute corresponding virtual to monitor number, set up and the attend a banquet corresponding relation of true number, monitoring group ID and virtual monitoring number of memory scheduling platform.
In cluster server, store monitoring group ID corresponding virtual in advance and monitor number, identical with each monitoring group corresponding virtual monitoring number information of storing among the MSC.
Step 4, cluster server send to MSC and monitor registration message, carry the corresponding virtual monitoring number of group ID and distribution.
Step 5, MSC are checked stored scheduling person's tabulation among the GCR, judge this virtual monitoring number whether in the dispatcher of this group ID correspondence tabulates, if, return the object information that succeeds in registration to cluster server, if do not exist, return the registration failure object information; Cluster server passes through this dispatching desk with the return results information of MSC and attends a banquet.
Step 6, monitoring users place dispatching desk are attended a banquet and are initiated monitored call to the dispatching desk gateway, carry and monitor flag information and monitor group id ID.That is: the calling number of this monitored call true number of attending a banquet for this dispatching desk, and call number is for monitoring flag information+monitoring group ID.Wherein, monitor flag information and can be a string monitoring condition code; Dispatching desk is attended a banquet and is initiated to carry the monitored call that this monitoring condition code prefix adds monitoring group ID to the dispatching desk gateway, and promptly called number is " monitoring condition code prefix+group ID ".
The data type of monitoring the condition code prefix can adopt BCD (Binary Coded Decimal is promptly with binary-coded decimal (BCD)), span for example: 0～9, A～F, length is 1～6.
Step 7, dispatching desk gateway according to monitor the condition code prefix judge be monitored call after, initiate authentication request to cluster server, carry true number and monitoring group ID that the dispatching desk of initiating monitored call is attended a banquet.
Step 8, cluster server are attended a banquet to dispatching desk and are carried out authentication.Specifically comprise:
After cluster server is received authentication request, the true number and the monitoring group ID that attend a banquet according to dispatching desk, the attend a banquet corresponding relation of true number, monitoring group ID and virtual monitoring number of the storage dispatching desk of the local storage of inquiry, if find the corresponding record that is complementary, then authentication is passed through, and obtains corresponding virtual and monitor number and return to the dispatching desk gateway by authentication response message.
Step 9, dispatching desk gateway carry virtual monitoring number that cluster server returns to MSC initiate initialization address message (Initiated Address Message, IAM), the request monitoring group calling.Wherein, caller is virtual monitoring number, and called is " monitoring condition code prefix+group ID ".
GCR among step 10, the MSC carries out authentication to this interception request, and promptly MSC inquires about virtual monitoring number whether in dispatcher's tabulation of monitoring group ID correspondence; If failed authentication, execution in step 11a; If the authentication success, execution in step 11b;
Still continue to use example, if the dispatcher that to judge virtual monitoring number be not monitoring group correspondence, then failed authentication is carried out subsequent step 11a.
Suppose that the virtual monitoring number that carries is " A " in the IAM message that MSC receives; Group ID is " 1 ", and the then dispatcher of the inquiry monitoring group of the GCR among the MSC " 1 " tabulation learns that it comprises virtual scheduling person " A ", and then authentication is passed through; After authentication is passed through, need also further to judge that the monitoring group whether in calling, if in calling, then carries out subsequent step 11b.If not in calling, (promptly be not activated), carry out subsequent step 11a.
Step 11a, comprise two kinds of situations:
(1) failed authentication: when promptly judging virtual monitoring number and not being the dispatcher of monitoring group correspondence, MSC returns clear message (REL message) for the dispatching desk gateway, carrying special cause value indication haves no right to monitor, this cause value uses ISDNYong Hubufen (Integrated Services Digital Network UserPart/ISDN User Part, ISUP) disconnection cause value, but flexible configuration;
(2) the group calling free time: authentication is passed through, is not activated but the monitoring group is current, and at this moment, MSC returns clear message to the dispatching desk gateway, carries the special cause value indication group calling free time, and this cause value uses the disconnection cause value of ISUP, but flexible configuration.
The dispatching desk gateway is attended a banquet the REL forwards to dispatching desk.
Step 11b: if the dispatcher that virtual monitoring number is the monitoring group, and the monitoring group is current calls out, then MSC returns response message (Acknowledged Message to the dispatching desk gateway, ACM) and response message (Answer Message, ANM) message allows described dispatching desk to attend a banquet and monitors; And attend a banquet between dispatching desk gateway and the MSC down link of corresponding circuits time slot of this dispatching desk joined the hearer side of meeting bridge.
Step 12, dispatching desk gateway are attended a banquet to transmit to dispatching desk and are monitored success response message.
Step 13, user attend a banquet by dispatching desk and begin to monitor group calling.
Step 14, user can attend a banquet by dispatching desk and press " speech key ", the request speech; Corresponding talk request is given MSC by the dispatching desk gateway forwards.
In the reality, can define " speech key " and " monitoring key " of Dual Tone Multifrequency between dispatching desk and MSC, coded format is the IA5 character.In calling talk process, monitoring users can use " speech key " and " monitoring key " to realize that table tennis switches (for same key time), switches between the speaker side of meeting bridge and hearer side.When monitoring users was pressed " speech key ", MSC was added to the uplink and downlink link of monitoring users in the meeting bridge simultaneously, and monitoring users can be said also and can listen; When monitoring users was pressed " monitoring key ", MSC only attends a banquet monitoring users place dispatching desk, and the down link of corresponding circuits time slot was added to the meeting bridge between dispatching desk gateway and MSC, and monitoring users can only be listened and can not say.
After step 15, MSC receive talk request, this dispatching desk corresponding uplink and downlink link of attending a banquet is joined the hearer side and the speaker side of meeting bridge simultaneously.
Step 16, user attend a banquet by this dispatching desk and realize monitoring and speech.
Step 17, user will send the instruction that finishes monitoring to attend a banquet by this dispatching desk, give MSC by the dispatching desk gateway forwards.
Step 18, MSC remove the monitored link of setting up, and group calling still can continue.
According to said method of the present invention, the invention provides a kind of system that group calling is carried out the active monitoring, adopt identical trunked communication system structure in the prior art, comprising: dispatching desk is attended a banquet, dispatching desk gateway, group service server and moving exchanging center MSC.For realizing the inventive method, in each entity, also comprise corresponding functional modules, be specially:
