The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , it is a flow chart of an embodiment of a method for intercom group networking according to the present application. A kind of walkie-talkie set networking method described, comprises the following steps:

Step S100: Continuously transmit time frames to the network nodes within the transmission range, so as to publish the network topology and the corresponding voice time slots of each network node in the time frame through the beacon time slot of the time frame, the time frame includes time division multiplexing Beacon slots, voice slots and contention slots used;

Step S200: Receive the time frame sent by the newly added network node, so as to obtain the network access request of the newly added network node through the competition time slot;

Step S300: Allocate voice time slots in a time frame to newly added network nodes, and update network topology.

Specifically, this application takes one of the multiple walkie-talkies as the main coordinator, and continuously transmits time frames to the outside to spread the topology information of the network through the beacons in the time frames and in the time-division multiplexed time frames. The voice time slot allocated by the walkie-talkie of the network node enables the existing network nodes in the network to determine the latest network topology and the voice time slot it owns in real time.

Obtain the network access request sent by the new network node through the competition time slot in the time frame, and apply for network access in the time period independent of the intercom voice transceiver and beacon transmission in the network.

Update the topology structure according to the network access application of the new network node and allocate time slots in the time frame for the new network node to communicate. This solution can build a radio communication network based on time division multiplexing, and through time division multiplexing, at least two groups of radios in the network can speak at the same time at the same time, so as to achieve the effect of full-duplex communication. This solution improves the communication efficiency of a group of walkie-talkies.

Preferably, before step S100, after the walkie-talkie is powered on, a walkie-talkie first scans whether there is an established multi-hop network nearby, and if so, directly applies to join this network as a network node. If it does not exist, the intercom acts as the master coordinator to create a new multi-hop intercom network. The network nodes in the network topology and the allocation of voice frames in the time frame are added according to the continuous application of new network nodes.

Further, the time frame also includes a control time slot, and the control time slot corresponds to a network node through allocation, and the method further includes:

Step S400: Control the network node to transmit the time frame to forward the network topology sent by the main coordinator and the corresponding control time slot and voice time slot of each network node in the time frame through the control time slot.

The full-duplex communication of the walkie-talkie network involved in this embodiment is realized by sending and receiving time-division multiplexed time frames, and a time frame is the smallest communication unit in this communication mode. Specifically, the time frame is divided into beacon time slots, control time slots, voice time slots, and contention time slots. Each time slot corresponds to a signal in a period of time in a time frame, so that the corresponding information is carried out according to the function of the time slot. The transmission of the network enables each network node in the network to share the link in the time length of one time frame.

Specifically, one time frame includes one beacon time slot Ts, which is used by the master coordinator to send beacons and control data. Several control time slots Tc are used by network nodes to transfer control data. Several voice time slots Ta are used by network nodes to send voice data. A contention time slot Tr is used by network nodes for contention, and is used for request signaling such as network access request, roaming request, and speech right application. The time frame period is subject to the processing period of the voice processing module.

Among them, the beacon time slot and control time slot are used as downlink signaling, including the network topology data and time slot allocation data sent by the main coordinator, and use the beacon time slot and control time slot to broadcast control data to the whole network. At the beginning of each time frame period, the main coordinator starts to send the control signaling. After receiving the control signaling from the parent node, the network node forwards the control signaling through its corresponding control time slot. After the main coordinator and the network nodes have sent the control data, all the network nodes in the network have obtained the latest network control data and synchronized the clock frequency. In the walkie-talkie network described in this embodiment, any network node, according to the network topology, can be the parent node of other network nodes, and the leaf node of other network nodes and the main coordinator.

The contention time slot is used as uplink signaling, which is sent by the network node to the parent node of the network node, including network access application, roaming, and speech right application. The report can be transmitted level by level, and the parent node will perform signaling feedback in the control time slot of the next time frame cycle, and the parent node will then send to the parent node of the next level, and also use the contention time slot to send.

Among them, the speed of DSP processing voice limits the number of people speaking at the same time, and the right to speak can be guaranteed by competing for time slots to ensure that the calls between various network nodes will not affect each other.

The network nodes need to be synchronized to the time frame period based on the main coordinator. The synchronization method is to use the control signaling sent by the parent node mounted by itself to perform synchronization calibration. If the parent node of the network node is the main coordinator, when the main coordinator sends control data, it is located at the starting point of the time frame period, so the adjacent network nodes can calculate the starting point of the time frame period of the main coordinator according to the communication delay. Thereby calibrating the local frame cycle timer to achieve synchronization with the network. Network nodes connected to the main coordinator through other network nodes cannot rely on the control signaling of the main coordinator for time frame synchronization, and they can only rely on their own parent nodes for time frame synchronization. According to the time slot interval between the control time frame of the parent node and the beacon plus the communication delay, it is the calibration value from the starting point of the time frame period of the main coordinator. The coordinator's time frame is periodically synchronized.

When the walkie-talkie in the network needs to send and receive voice, the voice activity detection is used to realize the dynamic application and release mechanism of the right to speak, so as to realize the multi-person full-duplex intercom function. The specific voice activity generation is that by detecting the voice of the microphone, when the user starts to speak, an application for the right to speak is initiated, and when the user does not speak, the right to speak is released. Due to the high speed of voice detection, network users can realize full-duplex intercom without manual intervention.

By setting the control time slot and forwarding the signaling sent by the coordinator through the control time slot, the walkie-talkie network can be extended into a multi-hop network, and the communication coverage that is farther than the communication distance between two walkie-talkies can be achieved through multi-hop technology.

In a multi-hop intercom system network, any network node at any time may become a relay forwarding node, or a leaf node. The relay forwarding node helps to forward control data and voice data, and the leaf node only sends its own data and receives data from other nodes. The switching of network nodes between relay forwarding nodes and leaf nodes is transparent to users. This solution can greatly expand the use range of the walkie-talkie network by forming a multi-hop network.

Further, referring to FIG. 2, the step S200 specifically includes:

Step S201 controls the network node to receive the time frame sent by the newly added network node, and obtains the network access request of the newly added network node through the competition time slot;

Step S202 controls the network node to send a time frame, so as to send a network access request of a newly added network node to the parent node of the network node through a competition time slot according to the network topology, until the network access request is transmitted to the main coordinator;

Step S203 controls the network node to receive the acceptance feedback through the control time slot corresponding to the parent node in the subsequent time frame, and sends the feedback to the leaf node or the newly added node through the control time slot corresponding to the network node in the subsequent time frame The network nodes of the network send acceptance feedback.

Specifically, the newly added network node detects the walkie-talkie network. During the network access process, it sends out a time frame in the form of broadcast, and sends a network access request through the competition time slot. The network node that receives the time frame sent by the newly added network node, As the father node of the newly added network node, the father node sends a time frame, and forwards the network access request of the newly added network node through the competition time slot, and forwards the network access request of the newly added network node to the main coordinator according to the network topology, The main coordinator sends the acceptance feedback through the beacon time slot, and the network node forwards the acceptance feedback to the child nodes through the control time slot, until the acceptance feedback is forwarded to the newly added network node through the control time slot through the parent node of the newly added network node. Node, the newly added network node is determined to join the network. When the newly added network node does not receive the above acceptance feedback, after a certain time interval, it will resubmit the network access request. This scheme is conducive to the orderly processing of the network access request of the newly added network node , to improve the network access efficiency and success rate of newly added network nodes.

Further, the method also includes:

Step S501: Control the network node to receive the time frame, so as to receive roaming requests sent by other network nodes through the contention time slot;

Step S502: controlling the network node to send a time frame, so as to send the roaming request to the parent node of the network node through a contention time slot according to the network topology, until the roaming request is transmitted to the main coordinator;

Step S503: the main coordinator adjusts the network topology according to the roaming request.

Specifically, the roaming request is made through the contention time slot, and the main controller is controlled to adjust the network topology and update the network topology. This scheme is beneficial for network nodes to adjust the network topology when the signal is poor, and this scheme improves the reliability of the walkie-talkie network.

In order to solve the above technical problems, the embodiment of the present application provides a walkie-talkie communication method, which adopts the following technical solution:

With reference to Fig. 3, a kind of walkie-talkie communication method, this method comprises:

Step Sa: receiving the time frame sent by the network node, so as to obtain the speaking right request of the network node through the competition time slot;

Step Sb: According to the topology of the walkie-talkie network, determine a group of network nodes corresponding to the speaking right request;

Step Sc: Allow the speaking right request according to the group of network nodes being in a serviceable state;

Step Sd: Send out a time frame to reply to the speaking right request through a beacon slot:

Step Se: send and receive time frames sequentially through the group of network nodes, so as to transmit voice through voice time slots.

When a network node wants to apply for and release the right to speak during the intercom process, it sends signaling to the main coordinator through the competition time slot. If the signaling cannot reach the main coordinator directly, the request will be forwarded in the contention time slot through multiple network nodes as transit nodes. The result responses of these request signalings are all fed back in beacon time slots and data time slots through control data. The CSMA/CD (Carrier Sense Multiple Access/Collision Detection Protocol) algorithm is used in the contention time slot to support all nodes that are not the main coordinator to use the time slot.

Referring to Figure 6 and Figure 7, when multiple nodes apply for speaking rights conflicts. After the walkie-talkie 5 sends the signaling in the contention time slot, it will receive the signaling reception feedback contained in the control data sent by its father node walkie-talkie 3 in the next time frame period, and judge whether its signaling has passed the father node walkie-talkie 3 Receive and forward. If no feedback is obtained, it will randomly wait for several time frame periods, and then send the application signaling. If the uplink signaling sent by each contention time slot is successfully received by the parent node, it will be responded and fed back by its parent node in the control data in the next time frame period. Network access signaling and roaming signaling are also sent using contention time slot signaling according to this feedback mechanism.

The communication between network nodes is implemented in the form of broadcast. When the network node receives the broadcast time frame and determines that the time frame needs to be forwarded by itself through the control time slot, it will further transmit the received time frame in the form of broadcast. The content of the voice time slot in the time frame is encapsulated into its own time frame and broadcasted until the time frame is further improved. The method also includes:

Step Sf: receiving the time frame sent by the network node, so as to obtain the release request of the network node through the competition time slot;

Step Sg: According to the release request, restore the corresponding network node to a serviceable state.

Affected by the switch of walkie-talkies in the network, the distance between walkie-talkies, and the interference of walkie-talkie signals, the established network topology cannot always meet the needs of network nodes. During this process, the network topology may have changing requirements. Refer to In Fig. 5 and Fig. 6, the walkie-talkie 5 decides to roam to the walkie-talkie 4 when it detects that the signal quality of the walkie-talkie 3 is poor and the signal quality of the walkie-talkie 4 is better. The walkie-talkie 5 first initiates a roaming application to the walkie-talkie 4 in the competition time slot, and the walkie-talkie 4 receives the request, and then relays the roaming application signaling to the upper-level transit node until the application signaling reaches the main coordinator walkie-talkie 1. After the walkie-talkie 1 approves the roaming application, it updates the networking topology and time slot allocation, and broadcasts new control data through the beacon time slot at the beginning of the next time frame. Walkie-talkie 4 receives new control data and becomes a transit node. The walkie-talkie 5 receives new networking data, and determines that its upper-level transit node is the walkie-talkie 4 .

Furthermore, since the transit node will occupy the control time slot and the voice time slot for data and voice relay and forwarding, the main coordinator should make reasonable allocation according to the limited conditions of bandwidth resources, and the number of hops and the scale of the network will also be reduced. bound by this condition. Especially for the allocation of voice time slots, if there are too many transit nodes, it will inevitably occupy the number of leaf nodes that can speak at the same time. Therefore, the main coordinator will control the number of transit nodes according to the limited conditions of the bandwidth.

Those of ordinary skill in the art can understand that realizing all or part of the processes in the methods of the above embodiments can be completed by instructing related hardware through a computer program, and the computer program can be stored in a computer-readable storage medium. During execution, it may include the processes of the embodiments of the above-mentioned methods. Wherein, the aforementioned storage medium may be a nonvolatile storage medium such as a magnetic disk, an optical disk, a read-only memory (Read-Only Memory, ROM), or a random access memory (Random Access Memory, RAM).

Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

This solution improves the communication efficiency of a group of walkie-talkies.
