If the MCPTT Client to receive it is described it is more-say user's group call other MCPTT Client information carry out really Recognize, then send other described MCPTT Client information to the MCPTT Client.
22. the call method according to claim 17 or 18, it is characterised in that methods described also includes：

In the case where external system calls application programming interface API to initiate multi-user's dial-up process, if described outer Portion's system, which is called, uses application layer to identify, then is used according to the application layer identity map to corresponding mission critical PTT Family group identification；

Identified according to the mission critical PTT groups of users and determine target critical task PTT user's group, and to the mesh Mark mission critical PTT user's group send it is more-say user's group call request message；

Receive that the target critical task PTT user's group returns it is more-say user's group close-talking response message；

If the terminal in the target critical task PTT user's group where each MCPTT Client supports sound mixing function, Open terminal audio mixing pattern；

Returning to multi-user voice group to the external system exhales foundation to complete information；Wherein, the MCPTT server are according to pre- First configuration uses end side audio mixing pattern, and the end side audio mixing pattern is sent to the target critical task PTT and used MCPTT Client in the group of family.
23. the call method according to claim 17 or 18, it is characterised in that methods described also includes：

In the case where the MCPTT server include right of speech control server, the right of speech control server is asked in user During right of speech, if current right of speech state is the free time, and receives the right of speech request of the MCPTT Client, then judge whether Right of speech is authorized to the MCPTT Client；

In the case where the judgment result is yes, right of speech assignment messages are sent to the MCPTT Client；And join to other rights of speech Right of speech, which is sent, with person takes message；

By the medium surface data forwarding that the MCPTT Client are sent to other rights of speech participant.
24. call method according to claim 23, it is characterised in that described to judge whether to the MCPTT Client Authorizing right of speech includes：

The threshold value for whether being more than or equal to maximum according to right of speech number is authorized and saying number of users, judges whether to the MCPTT Client Authorize right of speech.
25. call method according to claim 23, it is characterised in that the right of speech assignment messages include：Right of speech takes Time parameter.
26. call method according to claim 23, it is characterised in that the right of speech, which takes message, to be included：It is current to take The user list information of right of speech.
27. the call method according to claim 17 or 18, it is characterised in that methods described also includes：

In the case where the MCPTT server include right of speech control server, the right of speech controls server first During MCPTT Client distribute right of speech and talked, in the case of the 2nd MCPTT Client request speeches, receive The right of speech request that the 2nd MCPTT Client are sent；

Judge whether current right of speech occupant quantity is preset maximum value, and sentenced according to the priority of the current right of speech holder It is disconnected whether the right of speech of the first MCPTT Client to be transferred to the 2nd MCPTT Client；

In the case where being judged as YES, right of speech revocation instruction is sent to the first MCPTT Client, to the 2nd MCPTT Client sends right of speech assignment messages, and sends right of speech to all right of speech participants and take configured information；

The medium surface data that the 2nd MCPTT Client are sent carry out stereo process and are forwarded to other right of speech participants；

Wherein, if the priority of the first MCPTT Client is less than the 2nd MCPTT Client, and described first MCPTT Client re-request rights of speech after the 2nd MCPTT Client obtain right of speech, then refuse the first MCPTT The right of speech request that Client is sent.
