The telephone call system includes: a dispatch gateway 11, a dispatch server 12, and a destination switch 13. The destination telephone 14 is also shown in FIG.

It can be seen from FIG. 1 that the dispatching gateway 11 communicates with the dispatching server 12 via the IP network; the destination switch 13 communicates with the destination telephone 14 via the IP network; and the dispatching server 12 and the destination switch 13 communicate via the IP network.

The following describes the information interaction between the scheduling gateway 11, the scheduling server 12, and the destination switch 13, as shown in FIG. 2, which is a scheduling gateway and a scheduling server in a telephone call system provided by an embodiment of the present application. Signaling diagram of information exchange of the destination switch. The destination telephone 14 and the destination private network terminal 15 are also shown in FIG.

Step S201: The destination private network terminal 15 initiates a call request.

The private network terminal can be a DMR, a TETRA terminal, or a PDT terminal.

Step S202: When the scheduling gateway 11 listens to the call request or the call voice packet of the destination private network terminal 15, it sends the call request or the call voice packet to the dispatch server 12.

The call request carries the identifier of the destination private network terminal 15. It is also possible to carry a call voice packet with the destination private network terminal 15. Or, the dispatching gateway 11 listens to the call voice packet of the destination private network terminal again after listening to the destination private network terminal 12 to initiate a call request.

Step S203: The scheduling server 12 determines the calling number of the destination telephone and the address of the destination switch corresponding to the identifier of the destination private network terminal according to the correspondence between the pre-stored switch address, the call number of the telephone, and the identifier of the private network terminal.

Step S204: The dispatch server 12 determines that the destination telephone 14 is in the off-hook mode.

There are various ways for the dispatching server 12 to determine that the destination telephone 14 is in the off-hook mode. The embodiments of the present application provide, but are not limited to, the following.

First, before the dispatching gateway sends a call request to the dispatching server, the dispatching server 12 has set all the phones to the off-hook mode, that is, the connection between the private network terminal and the telephone is always present. In this case, the phone is always off-hook and wastes power.

Secondly, after the scheduling server 12 determines the destination telephone that the destination private network terminal needs to call, it is determined that the destination telephone is in the off-hook mode, and the specific steps are as follows:

Step S2041: The scheduling server 12 determines the current mode of the destination phone.

Step S2042: When the scheduling server 12 detects that the current mode of the destination phone is the off-hook mode, it determines that the destination phone is in the off-hook mode.

Step S2043: When the scheduling server 12 detects that the current mode of the destination phone is the idle mode, the off-hook instruction is generated.

The off-hook command carries the identification or telephone number of the destination telephone to enable the destination switch to determine which telephone is currently in the off-hook mode.

Step S2044: When receiving the off-hook command sent by the scheduling server, the destination switch 13 configures that the destination phone is in the off-hook mode, and feeds back the message that the destination phone is in the off-hook mode to the scheduling server.

Step S2045: When receiving the message that the destination phone returned by the destination switch is in the off-hook mode, the scheduling server 12 determines that the destination phone is in the off-hook mode.

Since steps S2041 through S2045 are optional steps, they are indicated by dashed boxes in FIG.

The upper dispatching gateway may be an IP dispatching gateway, the dispatching server may be an IP dispatching server, the destination telephone may be an IP destination telephone, and the destination switch may be an IPPBX. When the destination switch 13 receives the off-hook command sent by the scheduling server, the destination phone is in the off-hook mode, and the destination switch can invoke the IP interface of the IP destination phone to configure the IP destination phone to operate in the off-hook mode.

Step S205: The scheduling server 12 sends the call voice packet of the destination private network terminal to the destination switch.

It can be understood that if only one destination private network terminal currently sends a call voice packet to the destination telephone, the dispatch server 12 can send the call voice packet to the destination switch.

Step S206: The destination switch 13 is configured to send a call voice packet of the destination private network terminal to the destination phone.

In the telephone call system provided by the embodiment of the present application, the dispatching gateway 11 listens to the call voice packet of the destination private network terminal 15, and sends the call voice packet to the dispatch server 12, and the dispatch server 12 according to the pre-stored switch address and the telephone. The corresponding relationship between the calling number and the identifier of the private network terminal determines the calling number of the destination telephone and the address of the destination switch corresponding to the identifier of the destination private network terminal. And when it is determined that the destination phone is in the off-hook mode, the call voice packet of the destination private network terminal is sent to the destination switch. That is, when the destination private network terminal sends a call voice packet to the destination telephone, the dispatch server sets the state of the destination telephone to the off-hook mode, that is, the destination telephone automatically picks up the phone, and does not need the user at the telephone end to pick up the phone, avoiding There is a problem of lost voice or sound delay before the connection, and the efficiency of establishing a call between the private network terminal and the telephone is also improved.

It can be understood that in the prior art, the same phone can only listen to one or a group of private network terminals at the same time. When other private network terminals also need to make a call with the phone, the busy connection may occur. After waiting for the call to hang up the current call, the private network terminal can initiate the call again. This situation may lead to the loss of important information. Call voice package. It can be understood that, in the telephone call system provided by the embodiment of the present application, if there is currently only one destination private network terminal to the destination The telephone sends a call voice packet, and the dispatch server 12 can send the call voice packet to the destination switch.

If there are multiple private network terminals simultaneously sending call voice packets to one phone at the same time, that is, when multiple private network terminals form a group call, the scheduling server is further configured to: receive call voices sent by the plurality of private network terminals to the destination telephone During the packet, the call voice packets corresponding to the plurality of private network terminals are mixed to generate a mixed voice packet; and the mixed voice packet is sent to the destination switch. Correspondingly, the destination switch is further configured to: send the mixed voice packet to the destination phone.

The scheduling server stores the correspondence between the switch address, the call number of the phone, and the identifier of the private network terminal. One switch address may correspond to the call number of one or more phones, and the call number of one phone may correspond to one or more private network terminals. Logo.
