[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] Currently, full-duplex communication cannot be achieved in walkie-talkie networks, resulting in very few available communication resources and low call efficiency.

[0028] In the related art, it is proposed to use one of the multiple walkie-talkies as the main coordinator to continuously transmit time frames to the outside, so as to spread the network topology information and the voice time slots allocated to each walkie-talkie as a network node in the time division multiplexing time frame through the beacon in the time frame, so as to achieve a full-duplex effect. However, in this scheme, the network topology is chain-like, and the main coordinator and other walkie-talkies have the same communication distance. When the communication distance is far, the voice information needs to be forwarded through many network nodes to be sent to the target walkie-talkie. The message transmission delay is large, and the mobile networking method of small base station relay cannot be realized.

[0029] In view of this, an embodiment of the present invention provides a walkie-talkie communication method based on a base station type relay.

[0030] An intercom communication method based on a base station type relay provided in an embodiment of the present invention can be used in a base station. Specifically, the base station is a mobile base station that can be carried around and moved freely.

[0031] In one example, the base station includes a first short-range communication module, a long-range communication module, and a first main control module.

[0032] like Figure 1 The intercom communication method based on base station type relay of the embodiment of the present invention comprises the following steps:

[0033] Step S101, sending a time frame to a network node within a first communication range based on a first voice communication channel, so as to broadcast the network nodes corresponding to each voice time slot in the time frame through a synchronization time slot of the time frame, wherein the time frame includes a synchronization time slot, a contention time slot and at least two voice time slots, and each walkie-talkie serves as a network node;

[0034] Step S102, receiving a time frame sent by a network node within a first communication range based on a first voice communication channel, and receiving a time frame sent by other base stations within a second communication range based on a second voice communication channel, and acquiring voice information transmitted by the network node and other base stations through voice time slots of the received time frames;

[0035] Step S103, broadcasting the received voice information to network nodes within a first communication range based on a first voice communication channel, and broadcasting the received voice information to other base stations within a second communication range based on a second voice communication channel, wherein the second communication range is larger than the first communication range.

[0036] Specifically, the first voice communication channel is a communication channel between the base station and the surrounding walkie-talkie devices. The full-duplex communication of the walkie-talkie network in the embodiment of the present invention is realized by sending and receiving time division multiplexing time frames, and a time frame is the smallest communication unit in this communication mode.

[0037] like Figure 4 As shown, the time frame of the first voice communication channel includes a synchronization time slot, a contention time slot and at least two voice time slots. Each time slot corresponds to a signal in a period of time in a time frame. In this way, corresponding information is transmitted according to the function of the time slot, so that each network node in the network can use the link together for the time length of a time frame.

[0038] In the synchronization time slot, the first short-distance communication module of the base station regularly broadcasts synchronization signaling, and the nearby walkie-talkie devices can obtain relevant parameters of the base station based on the synchronization signaling.

[0039] There are several voice time slots, and several voice time slots 1 to voice time slots N are reserved time slots allocated by the base station for use by the walkie-talkie device for calls.

[0040] The competitive time slot is used for the walkie-talkie equipment to apply for network access, voice initiation, and roaming to the base station. Competing for the right to speak in the competitive time slot can ensure that the calls between the various network nodes will not affect each other.

[0041] The base station periodically sends time frames to network nodes within the first communication range based on the first voice communication channel to broadcast the voice time slots and base station information allocated to each network node. Each network node broadcasts the voice information to be sent through the allocated voice time slots.

[0042] The time frame structure of the second voice communication channel is the same as the time frame structure of the first voice communication channel, and also includes a synchronization time slot, a contention time slot and at least two voice time slots.

[0043] The second voice communication channel is a channel for communication between base stations, and its communication range is greater than the communication range of the first voice communication channel. For example, the communication range of the first voice communication channel is a circular area with a radius of 50m, while the communication range of the second voice communication channel is a circular area with a radius of 500m.

[0044] The current base station communicates with the walkie-talkie equipment and other base stations through the first voice communication channel and the second voice communication channel respectively. The current base station receives the network access application of the surrounding walkie-talkie equipment through the competitive time slot, and responds to the network access application to build the network topology. Each base station and the surrounding walkie-talkie equipment form a mesh topology, and the base stations form a chain topology, thus forming a flexible network structure. The base station and the walkie-talkie can be flexibly moved. When the location of the walkie-talkie changes, it only needs to roam to other base stations to achieve re-networking. The networking is flexible and convenient.

[0045] A walkie-talkie communication method based on base station relay in an embodiment of the present invention sends a time frame to a network node within a first communication range through a first voice communication channel, broadcasts the network node corresponding to each voice time slot in the time frame through a synchronization time slot of the time frame, receives the time frame sent by the network node within the first communication range based on the first voice communication channel, and receives the time frame sent by other base stations within the second communication range based on a second voice communication channel, obtains the voice information transmitted by the network node and the other base stations through the voice time slot of the received time frame, and then sends the received voice information to other base stations through a second voice communication channel with a larger communication range, broadcasts the received voice information to other base stations, and allows at least two groups of walkie-talkies or base stations in the network to speak simultaneously in the same time period through time division multiplexing, thereby realizing duplex communication within the first communication range and the second communication range.

[0046] At the same time, the network topology in the present invention forms a mesh topology structure with a base station and several walkie-talkies. Different base stations communicate through the second voice communication channel. Even if the communication distance is far, it does not need to pass through many network nodes in sequence for transmission, but through communication between base stations, short-delay communication can be achieved.

[0047] In some embodiments of the present invention, before sending a time frame to a network node within a first communication range based on a first voice communication channel in step S101, the process includes:

[0048] Step A1, receiving a time frame sent by a network node within a first communication range based on a first voice communication channel, and receiving a network access request or a roaming request sent by the network node through a contention time slot in the received time frame;

[0049] Step A2: adjusting the network topology according to the network access request or roaming request.

[0050] Specifically, Figure 5 As shown, the newly added network node sends a network access request to the base station through the contention time slot. The base station accepts the network access request through the contention time slot and gives feedback to the network access request, and broadcasts the feedback result to the network nodes within the first communication range through the synchronization time slot. When the newly added network node receives the feedback result, it confirms the network access. If the newly added network node does not receive the feedback result, it resubmits the network access request after a certain time interval. This solution is conducive to the orderly processing of the network access requests of the newly added network nodes, and improves the network access efficiency and success rate of the newly added network nodes.

[0051] The network node scans the network signal quality in real time. When the signaling sent in the synchronization time slot shows that the network is in a silent state, the network node will enter the reserved scanning time slot. During the reserved scanning time slot, the network node will scan the signal quality of other base stations and compare it with the signal of the current base station to apply for roaming switching.

[0052] Similarly, when a network node needs to roam from a current base station to a target base station, the network node sends a roaming request to the target base station through a contention time slot, and the target base station accepts the roaming request through a contention time slot and gives feedback to the roaming request, and broadcasts the feedback result to the network nodes within the first communication range and the current base station within the second communication range through a synchronization time slot. When the network node receives the feedback result, it confirms that the roaming is successful. If the network node does not receive the feedback result, it resubmits the roaming request after a certain time interval.

[0053] After the network access request or roaming request is successful, the base station will broadcast the acceptance result to other base stations and network nodes through the synchronization time slot, thereby updating the network topology in real time.

[0054] The embodiment of the present invention receives a network access request or a roaming request from a network node before sending a time frame, and adjusts the network topology accordingly, so that the network can dynamically adapt to the joining or movement of the node, thereby improving the flexibility and adaptability of the network.

[0055] In some embodiments of the present invention, before sending a time frame to a network node within a first communication range based on a first voice communication channel in step S101, the process includes:

[0056] Step B1, receiving a time frame sent by a network node within a first communication range based on a first voice communication channel, and receiving a voice initiation request sent by the network node through a contention time slot in the received time frame;

[0057] Step B2: assigning a corresponding network node to each voice time slot in the time frame according to the received voice initiation request.

[0058] In one example, there are five voice time slots, that is, the base station can allow five devices to speak at the same time. In reality, the number of devices connected to the base station can be much greater than five, and many of them are in a silent state. When a walkie-talkie device wants to start talking, it first initiates a speech request to the base station in the contention time slot, that is, a voice initiation request.

[0059] The base station receives the voice initiation request from the walkie-talkie device, allocates a voice time slot to the walkie-talkie device, and then broadcasts it in the synchronization time slot. The walkie-talkie device confirms which voice time slot it is speaking in from the synchronization time slot, and broadcasts the voice in that time slot.

[0060] Specifically, the embodiment of the present invention adopts a random backoff algorithm in the design of the contention time slot.

[0061] The contention time slot is a common signaling used by all walkie-talkie devices under the current base station. All walkie-talkie devices use this time slot in a competitive manner. When multiple devices send contention signaling at the same time and a conflict occurs, a random avoidance algorithm is used to repeat the transmission.

[0062] The steps of the random backoff algorithm are as follows:

[0063] Step 1: The intercom device sends signaling in the contention time slot.

[0064] Step 2: The two-way radio device checks whether the base station receives its own contention signaling in the synchronization time slot of the next frame period.

[0065] Step 3: If it is found in the synchronization signaling that the base station has received its own contention signaling, then the contention signaling is sent successfully.

[0066] Step 4: If no information is found in the synchronization signaling that its signaling is being processed, wait for N frame periods randomly and repeat step 2.

[0067] The embodiment of the present invention receives a voice initiation request from a network node and allocates a corresponding network node to a voice time slot. The method can achieve effective management of voice communication resources and ensure orderly communication.

[0068] In some embodiments of the present invention, step S103, broadcasting the received voice information to network nodes within the first communication range based on the first voice communication channel, and broadcasting the received voice information to other base stations within the second communication range based on the second voice communication channel, includes:

[0069] Step S1031, allocating the received voice information of each network node and other base stations to corresponding voice time slots respectively;

[0070] Step S1032, sending a time frame to a network node within the first communication range based on the first voice communication channel, and sending the received voice information to the network node within the first communication range through a corresponding voice time slot in the time frame;

[0071] Step S1033: Send a time frame to other base stations within the second communication range based on the second voice communication channel, and send the received voice information to other base stations within the second communication range through the corresponding voice time slot in the time frame.

[0072] In one example, after the current base station allocates corresponding voice time slots to each network node and other base stations, it continuously transmits voice to the network nodes within the first communication range by broadcasting, so as to conduct voice communication with each network node through a mesh network topology. Each network node receives the voice, thereby forming a first voice communication channel.

[0073] At the same time, the current base station continuously transmits voice to other base stations within the second communication range by broadcasting, and performs voice communication with each chain network topology and base station. Each base station receives the voice, thus forming a second voice communication channel.

[0074] The embodiment of the present invention allocates the received voice information to the corresponding voice time slot and broadcasts it to the network nodes and base stations within the first and second communication ranges respectively. This method improves the accuracy and efficiency of voice information transmission and ensures the timely delivery of information.

[0075] The embodiment of the present invention further provides a walkie-talkie communication method based on a base station type relay, which is applied to a walkie-talkie. The walkie-talkie includes a second short-range communication module and a second main control module.

[0076] like Figure 2 As shown, the intercom communication method based on base station type relay includes the following steps:

[0077] Step S201, receiving a time frame sent by a base station within a first communication range based on a first voice communication channel, so as to determine a voice time slot allocated to itself through a synchronization time slot of the time frame, wherein the time frame includes a synchronization time slot, a contention time slot and at least two voice time slots;

[0078] Step S202, based on sending a time frame through the first voice communication channel, broadcasting the voice information to be transmitted to other walkie-talkies or base stations within the first communication range through the voice time slot allocated to itself in the time frame, and broadcasting the voice information to be transmitted to other base stations within the second communication range based on the second voice communication channel through the base station that receives the voice information, wherein the second communication range is larger than the first communication range.

[0079] The intercom of the embodiment of the present invention determines its own voice time slot by receiving the time frame sent by the base station and broadcasts voice information in the time slot. This method enables the intercom to access the communication network in an orderly manner and expand the communication range by using the relay function of the base station.

[0080] In some embodiments of the present invention, before step S201, based on the first voice communication channel, receiving a time frame sent by a base station within the first communication range, the method includes:

[0081] Step C1, scanning the network signal quality of the currently connected base station and the network signal quality of other base stations, and comparing the network signal quality of the currently connected base station with the network signal quality of other base stations;

[0082] Step C2, when there are other base stations with better network signal quality than the currently connected base station, a time frame is sent to the base station with better network signal quality than the currently connected base station based on the first voice communication channel, and a network access request or a roaming request is sent through the contention time slot in the time frame.

[0083] Before receiving the time frame, the walkie-talkie scans and compares the signal quality of different base stations, and sends a network access request or roaming request when the signal quality is better, which helps the walkie-talkie select the best communication base station and improve the communication quality.

[0084] In some embodiments of the present invention, before step S201, based on the first voice communication channel, receiving a time frame sent by a base station within the first communication range, the method includes:

[0085] Step D1, sending a time frame to a base station within a first communication range based on a first voice communication channel, and sending a voice initiation request through a contention time slot in the time frame;

[0086] Step D1, receiving the time frame returned by the base station in response to the voice initiation request, and confirming whether the voice initiation request is successfully sent according to the synchronization time slot in the time frame returned by the base station;

[0087] Step D1, if the voice initiation request is not successfully sent, then wait for several frame periods randomly, resend the time frame to the base station within the first communication range based on the first voice communication channel, and send the voice initiation request again through the contention time slot in the time frame.

[0088] In this embodiment, a random backoff algorithm is used to receive a voice initiation request from a network node, and a corresponding network node is allocated to a voice time slot, so that effective management of voice communication resources can be achieved and orderly communication can be ensured.

[0089] The embodiment of the present invention further provides a base station, such as Figure 6 As shown, including:

[0090] A first short-range communication module, used for communicating with network nodes within a first communication range based on a first voice communication channel, wherein each intercom serves as a network node;

[0091] A long-distance communication module, used for communicating with other base stations within a second communication range based on a second voice communication channel, wherein the second communication range is larger than the first communication range;

[0092] The first main control module is used to control the first short-distance communication module and the long-distance communication module to execute the intercom communication method based on base station type relay applied to the base station in the above embodiment.

[0093] The embodiment of the present invention also provides a walkie-talkie, such as Figure 7 As shown, including:

[0094] A second short-range communication module, configured to communicate with a base station within a first communication range based on the first voice communication channel;

[0095] The second main control module is used to control the second short-range communication module to execute the intercom communication method based on base station type relay applied to the intercom in the above embodiment.

[0096] It should be understood that the intercom also includes UI units such as a microphone, a speaker, buttons and a display screen to complete the interaction with the user.

[0097] In one example, if Figure 3 As shown, the communication process between each base station and the intercom in the embodiment of the present invention is as follows:

[0098] Step S1, base station X1 / X2 / X3 / X4, etc. continuously transmits voice to walkie-talkie devices within a first communication range by broadcasting through a first short-range communication module, so as to perform voice communication with each device, and each device receives the voice, thereby forming a first voice communication channel;

[0099] Step S2: At the same time, the base station X1 continuously transmits voice to other base stations X2 / X3 / X4 and the like within the second communication range by broadcasting through the long-distance communication module, so as to communicate with other base stations by voice, and each base station receives the voice, thereby forming a second voice communication channel;

[0100] Step S3, the intercom A1 continuously transmits voice to the intercoms and nearby base stations within the first communication range by broadcasting through the second short-range communication module, so as to perform voice communication with the nearby base stations and intercoms, and each intercom or base station receives the voice, thereby forming a voice communication channel;

[0101] Step S4, after receiving the voice, the base station X1 near the intercom A1 broadcasts the voice to other base stations through the long-distance communication module to communicate with each base station. The voice is transmitted from the intercom A1 to the nearby base station X1, and then to each base station X2 / X3 / X4, completing the voice communication;

[0102] Step S5, the intercom near each base station repeats steps S3 and S4 to complete the language communication;

[0103] Step S6, a walkie-talkie near a base station, such as A1, can be freely moved to any other base station, quickly connect to the base station, and implement steps S1-S5;

[0104] Step S7: Each base station such as X1 can freely cross each other and move arbitrarily within the effective distance, realize free connection with nearby devices after movement, and realize steps S1-S5;

[0105] Step S8: Each base station such as X1 and each device can move freely. The network after the change of position is discovered and quickly repaired through the network topology to form a new network topology map.

[0106] The embodiment of the present invention establishes a first voice communication channel for communication and intercom at each base station and the intercoms around the base station through network topology, and establishes a second voice communication channel for intercom communication transmission between the base stations to establish a base station group; the base station can switch between the first voice communication channel and the second voice communication channel to form intercom communication between long-distance base stations and intercom communication with each intercom; all intercoms can intercom communicate with each other between nearby base stations, and can also move to any base station and then intercom communicate with nearby base stations; the intercom communication between the intercom and the base station can be mixed by the base station to transmit the sound to other base stations, and then the base station transmits the sound to the intercom near the base station, completing the full-duplex intercom communication between the entire large network.

[0107] At the same time, the network topology in the present invention forms a mesh topology structure with a base station and several walkie-talkies. Different base stations communicate through the second voice communication channel. Even if the communication distance is far, it does not need to pass through many network nodes in sequence for transmission. Instead, it achieves short-delay communication through communication between base stations, avoiding distortion of voice information caused by multiple forwardings.

[0108] In addition, the intercom of the present invention can automatically send network access requests or roaming requests in real time through the contention time slot in the time frame, flexibly adjust the accessed base station, and each base station thereby updates the accessed network node and network topology. Each base station and intercom can move freely and arbitrarily within the effective distance, automatically complete and adjust and repair the network topology networking, and can always maintain the communication status.
