All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Example one
Referring to fig. 1, fig. 1 is a schematic diagram of a wireless intercom system according to an embodiment of the present application; referring to fig. 1, the wireless intercom system includes:
the main machine is used for sending a control instruction to the extension set under the current channel through the special time slot so as to enable or disable the extension set, sending a voice signal through the special time slot, and receiving and playing the voice signal sent by the enabled extension set under the current channel; and the extension set is used for sending voice signals through the acquired communication time slot when the extension set is enabled, and receiving and playing voice signals sent by other enabled extension sets and voice signals sent by the host through the special time slot.
Specifically, the host has the authority to control the extension sets, and can transmit a control instruction to the extension sets through a dedicated time slot in a wireless frame under a current channel (a time slot for the host to use in the wireless frame) to enable or disable a certain extension set or some extension sets, transmit a voice signal through the dedicated time slot, and receive and play the voice signal transmitted by each enabled extension set. The method for enabling or disabling the extension by the host can be as follows: the main machine can be provided with a plurality of keys, and when all the keys on the main machine are started, the main machine starts all the extension sets under the current channel, so that all the extension sets under the current channel can listen and speak. When one or some keys on the host computer are disabled, the host computer disables the extension computer with the corresponding number, so that the extension computer cannot listen and speak. In addition, the host continuously transmits the control command through the dedicated slot regardless of whether the host transmits the voice signal through the dedicated slot.
The extension set receives the control of the host, when the extension set is started, if the extension set needs to send voice signals, the extension set can acquire idle communication time slots in a wireless frame, further send the voice signals through the acquired communication time slots, and can receive and play the voice signals sent by other started extension sets through the communication time slots under the current channel and the voice signals sent by the host through special time slots.
The wireless intercom system can support a plurality of deployment modes, including a single-host-multi-extension deployment mode, a single-host-multi-relay-multi-extension deployment mode, a multi-host-multi-relay-multi-extension deployment mode, a single-relay-multi-extension deployment mode, a multi-relay-multi-extension deployment mode and an extension off-line deployment mode. Specifically, a single-host-multiple-extension deployment mode is a mode in which only one host and any number of extensions exist in the system, as shown in fig. 1. The deployment mode of single host, multiple relays and multiple extension sets is that the system has only one host and multiple relays at the same time, there are any number of extension sets in the frequency channel where the host and each relay are located, and the host and the relays are connected through the IP network, as shown in fig. 2. The deployment mode of multi-host-multi-relay station-multi-extension station is that a plurality of hosts and a plurality of relay stations exist in the system, any number of extension stations exist under the frequency channel of each host and each relay station, and the hosts, the hosts and the relay stations are connected through an IP network, as shown in fig. 3. The single relay station-multiple extension station deployment mode is that one relay station and any number of extension stations exist in the system, as shown in fig. 4. The multiple relay station-multiple extension station deployment mode is that multiple relay stations and any number of extension stations exist in the system, and each relay station is connected through an IP network, as shown in fig. 5. The extension offline deployment mode is that there are any number of extensions in the system, and there are no hosts and relay stations, as shown in fig. 6.
In summary, in the wireless intercom system provided by the present application, the host may send a control instruction to the extension through the dedicated timeslot to control the state of the extension, select the extension allowed to send the voice signal, and the host may send the voice signal through the dedicated timeslot, and the enabled extension may send the voice signal through the communication timeslot, thereby implementing a flexible and convenient wireless communication between the host and the extension, saving time, and providing convenience for the staff.
Example two
In this embodiment, the wireless intercom system is provided with only one master, the master does not enable the wireless relay function, and the extensions are not grouped.
Specifically, the host may send control instructions to the extension set in the current channel through the dedicated time slot to enable or disable the extension set, and send voice signals through the dedicated time slot. When the extension set is started, if the voice signal needs to be sent, the extension set can acquire an idle communication time slot, further send the voice signal through the communication time slot, and play the received voice signals sent by other started extension sets under the current channel and the received voice signal sent by the host after mixing. At this time, since each enabled extension cannot receive the voice signal transmitted by itself, the extension does not echo. When the extension set is forbidden, the extension set does not have the authority of sending voice signals at the moment, and the voice signals sent by other extension sets and the host cannot be played.
Taking the example that the radio frame includes one dedicated timeslot and 8 communication timeslots, the dedicated timeslot is labeled 0, and the communication timeslots are labeled 1 to 8. In this case, the system can support one host and 8 extensions to have two-way conversation simultaneously. The host may send control commands as well as voice signals through dedicated time slot 0. When the enabled extension needs to send voice signals, a free communication time slot can be obtained from the 8 communication time slots from 1 to 8, and the voice signals are sent through the obtained communication time slot. And can receive and play the voice signals transmitted by other enabled extension sets in the current channel through the communication time slot and the voice signals transmitted by the main machine through the special time slot. The disabled extension is then unable to send voice signals and play voice signals.
EXAMPLE III
In this embodiment, the wireless intercom system is provided with only one host, and the host enables the wireless relay function, and the extension sets are not grouped and have echoes.
In particular, the host sends control commands through dedicated time slots to enable or disable the extension. The enabled extension set acquires an idle communication time slot when needing to transmit the voice signal and transmits the voice signal through the acquired communication time slot. The host receives the voice signals sent by each communication time slot, can mix the voice signals of the host with the received voice signals sent by the extension set, and then sends the voice signals through the special time slot. Therefore, the enabled extension set can receive and play the voice signals sent by other extension sets through the communication time slot, and also receive and play the voice signals sent by the host through the special time slot (including the voice signals sent by the extension sets), and then the extension sets have echo at the moment.
Similarly, the wireless frame includes a dedicated timeslot 0 and 8 communication timeslots, so that the system can support a host and 8 extensions to perform two-way call simultaneously. The host may send control commands as well as voice signals through dedicated time slot 0. When the enabled extension needs to send voice signals, a free communication time slot can be obtained from the 8 communication time slots from 1 to 8, and the voice signals are sent through the obtained communication time slot. The enabled extension set can also receive and play the voice signals sent by other extension sets through the communication time slot, and receive and play the voice signals of the host and the forwarded voice signals of the extension sets, which are sent by the host through the special time slot. The disabled extension is then unable to send voice signals and play voice signals.
Example four
In this embodiment, the wireless intercom system is provided with only one host, and the host enables the wireless relay function, and the extension sets are not grouped and have no echo.
Specifically, the host transmits a control command through a dedicated slot to enable or disable the extension, and transmits a voice signal of the host through the dedicated slot. The enabled extension set acquires an idle communication time slot when needing to transmit the voice signal and transmits the voice signal through the acquired communication time slot. The host receives the voice signals sent by each communication time slot and forwards the voice signals sent by the extension set through the corresponding forwarding time slot. The enabled extension set can receive voice signals sent by other extension sets through communication time slots, voice signals forwarded by the host through forwarding time slots and voice signals sent by the host through special time slots, and after the voice signals sent by the enabled extension set are removed from the received voice signals, other received voice signals are mixed and played.
Taking the example that the radio frame includes one dedicated timeslot, 4 communication timeslots and 4 forwarding timeslots, the dedicated timeslot is labeled 0, the communication timeslots are labeled 1 to 4, and the forwarding timeslots are labeled 5 to 8. In this case, the system can support two-way conversation between one host and 4 extensions. The host may send control commands as well as voice signals through dedicated time slot 0. When the enabled extension needs to send voice signals, a free communication time slot can be obtained from the 4 communication time slots from 1 to 4, and the voice signals are sent through the obtained communication time slot. And can receive the voice signal that other extension sent through the communication time slot and receive and broadcast the host computer through the voice signal of the host computer oneself that the specialized time slot sends and the host computer through transmitting the voice signal that the extension sent that the time slot forwards. For example, the host transmits a voice signal through the forwarding slot 5 corresponding to the forwarded communication slot 1. At this time, the enabled extension may receive the voice signal transmitted by the same extension twice. The enabled extension set can remove the voice signals sent by the extension set from all the received voice signals and then play the voice, so that the extension set does not have echo. The disabled extension is then unable to send voice signals and play voice signals.
EXAMPLE five
In this embodiment, the wireless intercom system is provided with only one master, and the extensions perform grouping.
In particular, the host sends control instructions over dedicated time slots to enable or disable all extensions within a certain packet or packets, and sends the host's voice signals over dedicated time slots. When needing to send voice signals, the extension set in the enabled packet can acquire the idle communication time slot and send the voice signals through the acquired communication time slot, and can receive and play the voice signals sent by the host and the voice signals sent by other extension sets of the packet where the extension set is located through the communication time slot. When the extension set in the forbidden group needs to send the voice signal, the extension set in the forbidden group can also acquire the idle communication time slot to send the voice signal, and plays the voice signal sent by other extension sets in the group where the extension set is located, but does not allow the voice signal sent by the main machine through the special time slot to be played. After the host receives the voice signals sent by the extension sets of different groups through the communication time slot, the voice signals sent by the extension sets of the forbidden group are eliminated, and the rest voice signals are played after being mixed. The voice signal sent by each extension carries the number of the packet where the extension is located, so as to identify the packet where the extension is located.
EXAMPLE six
In this embodiment, the wireless intercom system is provided with only one host, the host does not start the wireless relay function, the extension performs grouping, and the extension has no echo.
In particular, the host sends control instructions over dedicated time slots to enable or disable all extensions within a certain packet or packets, and sends the host's voice signals over dedicated time slots. When needing to send voice signals, the extension set in the enabled packet can acquire the idle communication time slot and send the voice signals through the acquired communication time slot, and can receive and play the voice signals sent by the host and the voice signals sent by other extension sets of the packet where the extension set is located through the communication time slot. When the extension set in the forbidden group needs to send the voice signal, the extension set in the forbidden group can also acquire the idle communication time slot to send the voice signal, and plays the voice signal sent by other extension sets in the group where the extension set is located, but does not allow the voice signal sent by the main machine through the special time slot to be played. After the host receives the voice signals sent by the extension sets of different groups through the communication time slot, the voice signals sent by the extension sets of the forbidden group are eliminated, and the rest voice signals are played after being mixed. The voice signal sent by each extension carries the number of the packet where the extension is located, so as to identify the packet where the extension is located.
Taking the wireless frame including a dedicated timeslot and 8 communication timeslots as an example, the dedicated timeslot is labeled 0, and the communication timeslots are labeled 1 to 8, at this time, the system can support a host and 8 extensions to perform two-way communication simultaneously. The host may send control commands as well as voice signals through dedicated time slots. When the enabled packet extension needs to send voice signals, a free communication time slot can be obtained from the 8 communication time slots from 1 to 8, the voice signals are sent through the obtained communication time slot, and the voice signals sent by the host through the special time slot are played. When the extension set in the forbidden group needs to send the voice signal, an idle communication time slot can be obtained from the 6 communication time slots from 1 to 8, and the voice signal is sent through the obtained communication time slot, so that the voice signal sent by other extension sets of the group where the extension set is located through the communication time slot can be played, but the voice signal of the host sent by the host through the special time slot cannot be played.
EXAMPLE seven
In this embodiment, the wireless intercom system is provided with only one host, the host enables the wireless relay function, the extensions perform grouping, and the extensions have echoes.
Specifically, the host sends a control instruction through a special time slot to enable or disable the extension set(s) in a certain group, sends the voice signal of the host through the special time slot, mixes the received voice signal sent by the extension set(s) in the same group, and forwards the voice signal sent by the extension set(s) in the same group through the corresponding forwarding time slot after mixing. When needing to send voice signals, each extension set in the enabled packet can acquire an idle communication time slot and send voice signals through the acquired communication time slot, and receive and play voice signals (optional) sent by the extension set in the packet in which the extension set is located through a special time slot, voice signals sent by the host through the special time slot and voice signals forwarded by the host through a forwarding time slot in the packet in which the extension set is located, wherein the extension set has echoes at the moment. When the extension set in the forbidden group needs to send the voice signal, the extension set can acquire the idle communication time slot to send the voice signal, and plays the voice signal sent by other extension sets in the group where the extension set is located, but does not allow the voice signal of the host set itself sent by the host set through the special time slot to be played. The host receives the voice signals sent by the extension sets through the communication time slot and rejects the voice signals sent by the extension sets of the forbidden groups, and then the rest voice signals are mixed and played. The voice signal sent by each extension carries the number of the packet where the extension is located, so as to identify the packet where the extension is located.
Taking the example that the wireless frame includes a dedicated timeslot, 4 communication timeslots and 4 forwarding timeslots, the system can support a host and 4 extensions to perform two-way communication simultaneously. The host may send control commands as well as voice signals through dedicated time slot 0. When the enabled packet extension needs to send voice signals, an idle communication time slot can be acquired from 4 communication time slots of 1 to 4, the voice signals are sent through the acquired communication time slot, and the voice signals of the host sent through the special time slot by the host and the voice signals (including the voice signals sent by the extension) sent by the extension of the same packet and forwarded by the host through the corresponding forwarding time slot of 5 to 8 can be received and played.
Example eight
In this embodiment, the wireless intercom system is provided with only one host, the host enables the wireless relay function, the extensions perform grouping, and the extensions have no echo.
Specifically, the host sends control instructions through the special time slot to enable or disable the extension set in a certain packet or certain packets, and sends the voice signal of the host through the special time slot, and forwards the received voice signal of the extension set through the corresponding forwarding time slot. When needing to send voice signals, each extension set in the enabled packet can acquire an idle communication time slot and send the voice signals through the acquired communication time slot, and receives the voice signals sent by the extension sets through the special time slot, the voice signals sent by the host through the special time slot and the voice signals forwarded by the host through the forwarding time slot, and plays the rest voice signals after removing the voice signals sent by the extension sets from all the received voice signals, so that the extension sets have no echo. When the extension set in the forbidden group needs to send the voice signal, the extension set can also acquire the idle communication time slot to send the voice signal, but the voice signal sent by the host is not allowed to be played, but the voice signals sent by other extension sets of the group in which the extension set is located, the voice signals of which are removed, can be played. After receiving the voice signals sent by the extension sets through the communication time slots, the host machine rejects the voice signals sent by the extension sets of the forbidden groups, and then mixes the rest voice signals and plays the voice signals. The voice signal sent by each extension carries the number of the packet where the extension is located, so as to identify the packet where the extension is located.
Similarly, the wireless frame includes a dedicated timeslot, 4 communication timeslots and 4 forwarding timeslots, and at this time, the system can support a host and 4 extensions to perform two-way communication simultaneously. The host may send control commands as well as voice signals through dedicated time slot 0. When the enabled packet extension needs to send voice signals, an idle communication time slot can be acquired from 4 communication time slots from 1 to 4, the voice signals are sent through the acquired communication time slot, and the voice signals of the host sent by the host through the special time slot and the voice signals sent by the extension forwarded by the host through the corresponding forwarding time slot from 5 to 8 (the voice signals sent by the extension are not played) can be received and played.
Example nine
In this embodiment, the wireless intercom system is provided with more than one host or one host and at least one relay station, and the host does not enable the wireless relay function, and the extension sets are not grouped.
Specifically, the relay station is a device having only a voice signal transfer function and no control function. The relay station is connected with the host machine or the host machine and the host machine through an IP network, each host machine or the relay station belongs to different channels, and wireless frames under the channels of the host machines and the relay stations respectively comprise a special time slot. The host can send control instructions and voice signals to the extension set under the channel to which the host belongs, namely under the current channel through the special time slot, and can receive voice signals transmitted by extension sets under other channels forwarded by other hosts or relay stations through the IP network. Furthermore, after receiving the voice signals sent by the extension sets in other channels through the IP network, the host sends the voice signals sent by the extension sets in other channels through the special time slot, so that the enabled extension set in the current channel can receive the voice signals sent by the extension sets in other channels. In addition, the host computer mixes the received voice signals sent by the extension sets including the extension set under the current channel and the extension sets under other channels and plays the mixed voice signals. In addition, the host computer can also send the received voice signal sent by the extension computer under the current channel to other host computers or relay stations through the IP network after mixing the voice signal.
When the extension set under the current channel is started, if the extension set under the current channel needs to send a voice signal, the extension set can acquire an idle communication time slot, and then sends the voice signal through the communication time slot, and the received voice signal sent by other started extension sets under the current channel, the voice signal of the host sent by the host and the voice signal sent by the extension set under other channels sent by the host are mixed and played, at the moment, each started extension set cannot receive the voice signal sent by the extension set, and therefore the extension set does not have echo. When the extension set is disabled, the extension set cannot send voice signals and play voice signals.
Taking the case that the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0 and 8 communication timeslots, at this time, one host and 8 extensions can simultaneously perform two-way conversation in each channel. The host in the current channel can send the control command and the voice signal through the special time slot 0, and receive the voice signal sent by the extension set in another channel forwarded by another host through the IP network. When the extension set enabled in the current channel needs to send a voice signal, an idle communication time slot can be acquired from 8 communication time slots from 1 to 8, the voice signal is sent through the acquired communication time slot, and the voice signal sent by other extension sets in the current channel and the voice signal sent by the host (including the voice signal of the host and the voice signal of an extension set in another channel) are received and played. The disabled extension is then unable to send voice signals and play voice signals.
Example ten
In this embodiment, the wireless intercom system is provided with more than one host or one host and at least one relay station, and the host enables the wireless relay function, the extension is not grouped, and the extension has echo.
Specifically, the host may send a control command and a voice signal to the extension set in the current channel through the dedicated timeslot, and may receive the voice signal sent by the extension set in another channel and forwarded by another host or the relay station through the IP network. Further, after receiving the voice signals sent by the extension sets in other channels through the IP network, the host sends the voice signals sent by the extension set in the current channel and the extension sets in other channels through the special time slot, so that the enabled extension set in the current channel can receive the voice signals sent by the extension sets in the current channel and other channels. In addition, the host computer mixes the received voice signals sent by the extension sets including the extension set under the current channel and the extension sets under other channels and plays the mixed voice signals. In addition, the host computer also mixes the received voice signals sent by the extension set under the current channel and sends the voice signals to other host computers or relay stations through the IP network, so that the voice signals sent by the extension set under the current channel are forwarded to the extension sets under other channels through other host computers or relay stations.
When the extension set in the current channel is started, if a voice signal needs to be sent, the extension set can acquire an idle communication time slot, and then send the voice signal through the communication time slot, and play the received voice signal sent by the extension set in the current channel through the communication time slot and the received voice signal sent by the host (including the voice signal of the host, the voice signal of the extension set in the current channel and the voice signals of the extension sets in other channels) after mixing. Since the played voice signal includes the voice signal of the extension set itself, there is an echo. When the extension set is forbidden, the extension set does not have the authority of sending the voice signal at the moment, and the voice signal cannot be played.
Taking the case that the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0 and 8 communication timeslots, at this time, one host and 8 extensions can simultaneously perform two-way conversation in each channel. Under the current channel, the host can send a control instruction through a special time slot, receive a voice signal of an extension set under another channel forwarded by another host through an IP network, and send the voice signal of the host and the voice signals of the extension set under the current channel and the extension set under another channel through the special time slot. When the extension set enabled under the current channel needs to send the voice signal, an idle communication time slot can be obtained from 8 communication time slots from 1 to 8, the voice signal is sent through the obtained communication time slot, and the voice signals of other extension sets and the host are received and played (including the voice signal of the host, the voice signal of the extension set under the current channel and the voice signal of the extension set under the other channel). The disabled extension is then unable to send and play voice signals.
EXAMPLE eleven
In this embodiment, the wireless intercom system is provided with more than one host or one host and at least one relay station, and the host enables the wireless relay function, and the extension is not grouped and has no echo.
Specifically, the host may send a control command and a voice signal to the extension set in the current channel through the dedicated timeslot, and may receive the voice signal sent by the extension set in another channel and forwarded by another host or the relay station through the IP network. Furthermore, after receiving the voice signals sent by the extension sets in other channels through the IP network, the host sends the voice signals sent by the extension sets in other channels through the special time slot, so that the enabled extension set in the current channel can receive the voice signals sent by the extension sets in other channels. In addition, the host sends out the received voice signal sent by the extension set under the current channel through the corresponding forwarding time slot. And sending the voice signal sent by the extension set under the current channel to the host computer or the relay station under other channels through the IP network, so as to forward the voice signal sent by the extension set under the current channel to the extension set under other channels through other host computers or relay stations.
When the extension set in the current channel is started, if the voice signal needs to be sent, the extension set can acquire an idle communication time slot, and then sends the voice signal through the communication time slot, and plays the remaining voice signal after removing the voice signal of the extension set from the received voice signal sent by the extension set in the current channel through the communication time slot, the voice signal sent by the host machine through the special time slot (including the voice signal of the host machine and the voice signals of the extension sets in other channels) and the voice signal of the extension set in the current channel sent by the host machine through the forwarding time slot. Because the played voice signal has already rejected the voice signal of oneself, therefore the extension has no echo. When the extension set is forbidden, the extension set does not have the authority of sending the voice signal at the moment, and the voice signal cannot be played.
Taking the case that the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0, 4 communication timeslots and 4 forwarding timeslots, at this time, 1 host and 4 extensions can be supported to perform two-way conversation simultaneously in each channel. In the current channel, the host can send a control instruction through a special time slot, receive a voice signal of an extension set under another channel forwarded by another host through an IP network, send the voice signal of the host and the voice signal of the extension set under another channel through the special time slot, and send the voice signal of the extension set under the current channel through the forwarding time slot. When the extension set which is enabled under the current channel needs to send the voice signal, an idle communication time slot can be obtained from 4 communication time slots from 1 to 4, the voice signal is sent through the obtained communication time slot, and the voice signals of other extension sets and the host except the own voice signal are received and played. The disabled extension is then unable to send and play voice signals.
Example twelve
In this embodiment, the wireless intercom system is provided with more than one host or one host and at least one relay station, the host does not start the wireless relay function, the extensions perform grouping, and the extensions have no echo.
Specifically, the current host can send the control command and the voice signal of the current host through the dedicated time slot, and can send out the voice signal sent by the extension set in the same packet under other channels received through the IP network through the corresponding forwarding time slot. In addition, the host can also mix the voice signals sent by the extension set under the current channel through the communication time slot according to the packets in which the voice signals are located, and then send the voice signals to other hosts or relay stations through the IP network, so that the voice signals can be further forwarded through other hosts or relay stations. And after the host receives the voice signals of the extension set, after the voice signals sent by the extension set in the forbidden group are removed, the remaining voice signals are mixed and played.
Each extension set in the enabled grouping under the current channel can acquire the idle communication time slot when needing to send the voice signal, send the voice signal through the acquired communication time slot and receive and play the voice signal sent by the host, wherein the voice signal of the extension set in the same grouping under other channels forwarded by the host, the voice signal of the host under the current channel and the voice signal of the host under other channels are received and played. When the disabled extension in the packet needs to transmit the voice signal, the extension can acquire the idle communication time slot to transmit the voice signal, and the voice signal transmitted by the host is not allowed to be played.
Similarly, for example, the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0, 4 communication timeslots, and 4 forwarding timeslots, at this time, a host and 4 extensions can simultaneously perform two-way conversation in each channel. In the current frequency channel, the host can send the control command, the voice signal of the host and the voice signals of the hosts in other frequency channels received by the IP network through the special time slot 0, and send the voice signals of the extension sets in the packets in other frequency channels through the forwarding time slot. When an extension set in the enabled packet in the current frequency channel needs to transmit a voice signal, a free communication time slot can be acquired from 4 communication time slots from 1 to 4, the voice signal is transmitted through the acquired communication time slot, and the voice signals transmitted by other extension sets and the host are received and played. The disabled extension can not play the voice signal sent by the host.
EXAMPLE thirteen
In this embodiment, the wireless intercom system is provided with more than one host or one host and at least one relay station, the host enables the wireless relay function, the extensions perform grouping, and the extensions have echoes.
Specifically, the current host may send the control instruction and the voice signal of the current host through the dedicated timeslot, and may send out the voice signal sent by the extension set in the same group in another channel received through the IP network and the voice signal of the extension set in the same group in the current channel after mixing the voice signals through the corresponding forwarding timeslot. In addition, the host can also mix the voice signals in the same group sent by the extension set under the current channel through the communication time slot and then send the mixed voice signals to other hosts or relay stations through the IP network, so that the voice signals can be further forwarded through other hosts or relay stations. And after the host receives the voice signals of the extension set, after the voice signals sent by the extension set of the forbidden group are removed, the remaining voice signals are mixed and played.
When needing to send voice signals, each extension in the enabled grouping under the current channel can acquire an idle communication time slot, send voice signals through the acquired communication time slot and receive and play the voice signals sent by the host, wherein the voice signals of the extension in the grouping of other channels, the voice signals of the host under the current channel and the voice signals of the host under the other channels are forwarded by the host. When the disabled extension in the packet needs to transmit the voice signal, the extension can acquire the idle communication time slot to transmit the voice signal, and the voice signal transmitted by the host is not allowed to be played.
Similarly, for example, the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0, 4 communication timeslots, and 4 forwarding timeslots, at this time, a host and 4 extensions can simultaneously perform two-way conversation in each channel. In the current frequency channel, the host can send a control command, a voice signal of the host and a voice signal of the host in other frequency channels received by an IP network through the special time slot 0, and send a voice signal of an extension in a group in other frequency channels and a voice signal of an extension in the same group in the current frequency channel through the forwarding time slot. When an extension set in the enabled packet in the current channel needs to send a voice signal, an idle communication time slot can be acquired from 4 communication time slots from 1 to 4, the voice signal is sent through the acquired communication time slot, and the voice signals sent by other extension sets and the host computer with own voice signals removed are received and played. The disabled extension can not play the voice signal sent by the host.

In addition, the host can receive voice signals transmitted by extension sets in packets under other channels forwarded by other hosts or relay stations through the IP network, and transmit the voice signals through corresponding forwarding time slots. In addition, after receiving the voice signal sent by other host computer through IP network, the host computer sends the voice signal of other host computer to the extension set under the current channel through the special time slot. And after receiving the voice signal sent by the extension set in the packet under the current channel through the communication time slot, the host further sends the voice signal sent by the extension set under the current channel through the corresponding forwarding time slot, and according to the packet condition of each extension set, the host sends the voice signal sent by the extension set of the same packet to other hosts or relay stations through an IP network after mixing the voice signal, and sends the voice signal of the host to other hosts or relay stations through the IP network.
When the enabled packet extension needs to send voice signals, the enabled packet extension can acquire the idle communication time slot in the current channel and send the voice signals through the acquired communication time slot, and at least receive and play the voice signals sent through the special time slot and the forwarding time slot. When the disabled grouping extension needs to send voice signals, the disabled grouping extension can acquire the idle communication time slot under the current channel and send the voice signals through the acquired communication time slot, and receive and play the voice signals sent by other extensions which are in the same grouping with the extension in the voice signals sent by the forwarding time slot, but not play the voice signals of the host.
Taking the case that the wireless intercom system includes two hosts, and the wireless frame includes a dedicated timeslot 0, 3 communication timeslots, and 5 forwarding timeslots (including the forwarding timeslots of packets in 3 current channels and the forwarding timeslots of packets in 2 other channels), at this time, 1 host and 3 extension sets can support simultaneous two-way conversation in each channel. Under the current channel, the host can send a control instruction and a voice signal of the host (which can include a voice signal of the host and a voice signal of another host) to the extension set of each group under the current channel through the dedicated time slot 0, and can correspondingly forward the voice signal sent by the extension set under the current channel through the forwarding time slots 4 to 6, and can correspondingly forward the voice signal sent by the extension set under another channel and forwarded by another host through the IP network, and can forward the voice signal sent by the extension set under the current channel through the communication time slots 1 to 3 and the voice signal of the host to another host through the IP network, wherein the voice signal sent by the extension set under the current channel and the voice signal of the host can be forwarded by another host through the. When the extension set in the enabled packet needs to transmit voice signals in the current frequency channel, a free communication time slot can be obtained from 3 communication time slots 1 to 3, the voice signals are transmitted through the obtained communication time slot, and at least the voice signals transmitted through the special time slot 0 and the forwarding time slots 4 to 8 are received and played. When the disabled packet extension needs to transmit voice signals, a free communication time slot can be obtained from the 3 communication time slots 1 to 3 for voice signal transmission, and the voice signals of the host cannot be played.
