Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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.
The wireless ad hoc network method provided by each embodiment of the present application may be applied to at least one transit device in a target area, where each transit device may operate using four time slots, where the four time slots are: a first time slot, a second time slot, a third time slot, and a fourth time slot.
It should be noted that, all the transit devices in the target area always keep all the frames and time slots aligned, so as to ensure the consistency of the data forwarded to the terminal in terms of time.
As shown in fig. 1, a flowchart of embodiment 1 of a communication method provided in the present application may include the following steps:
step S11, when the target area includes at least two relay devices, each relay device selects two time slots from the first time slot, the second time slot, and the third time slot, respectively, for receiving data and sending data, and takes the time slot for receiving data as a receiving time slot and the time slot for sending data as a sending time slot.
Step S12, the first target relay device in the at least two relay devices uses the first frequency in its receiving time slot to receive the data from the calling terminal, and uses the second frequency in its sending time slot to forward the data of the calling terminal to the relay devices in its coverage area.
The first target relay device may be understood as: and the transfer equipment is positioned in the coverage range of the calling terminal.
In this embodiment, the calling terminal sends data in one of the four time slots using the first frequency, and correspondingly, the first target transfer device selects the time slot corresponding to the calling terminal and receives the data of the calling terminal using the first frequency. For example, if the calling terminal transmits data using the first frequency in the first time slot, the first target transfer device receives data using the first frequency in the first time slot. If the calling terminal uses the first frequency to send data in the second time slot, the first target transfer device uses the first frequency to receive data in the second time slot.
The magnitude of the first frequency can be set according to needs, and is not limited in this application.
A first target relay device in the at least two relay devices receives data from the calling terminal using a first frequency in its receiving time slot, and forwards the data of the calling terminal to the relay devices in its coverage area using a second frequency in its sending time slot, which may be understood as: and a first target transfer device in the at least two transfer devices receives the data from the calling terminal by using a first frequency in the receiving time slot of each frame, and forwards the data of the calling terminal to the transfer devices in the coverage range by using a second frequency in the sending time slot of each frame.
In this embodiment, the first frequency and the second frequency are different. The first target transfer equipment uses the second frequency to transfer the data of the calling terminal to the transfer equipment in the coverage range of the first target transfer equipment in the sending time slot of the first target transfer equipment, so that the terminal cannot receive the data transferred by using the second frequency, and the accuracy of communication is ensured.
In step S13, the other relay devices in the at least two relay devices receive the data from the relay devices using the second frequency in their receiving time slots, and forward the data from the relay devices using the second frequency in their sending time slots.
The other transfer devices of the at least two transfer devices may be understood as other transfer devices of the at least two transfer devices except for the first target transfer device.
The other relay devices in the at least two relay devices receive the data from the relay device using the second frequency in their receiving time slots, and forward the data from the relay device using the second frequency in their sending time slots, which can be understood as: the other relay devices of the at least two relay devices receive the data from the relay devices using the second frequency at their receiving time slots per frame and forward the data from the relay devices using the second frequency at their transmitting time slots per frame.
It should be noted that the reception time slots of other relay devices are the same as the transmission time slots of the relay devices to which data is transmitted. Similarly, the transmission time slot of the other relay device is the same as the reception time slot of the relay device that receives the data transmitted by the other relay device.
Step S14, each of the relay devices forwards the data of the calling terminal to the terminals within its coverage area using the first frequency in the fourth time slot of each frame, starting from a target frame, where the target frame is the earliest frame in which each of the relay devices can receive the data from the calling terminal.
The target frame is the earliest frame that each transfer device can receive the data from the calling terminal, and can ensure that each transfer device does not lose the data of the calling terminal in the process of forwarding the data of the calling terminal to the terminals in the coverage range of the transfer device by using the first frequency in the fourth time slot of each frame from the target frame, thereby ensuring the reliability of the communication of the wireless ad hoc network.
In this embodiment, each of the transit devices starts from a target frame, and forwards the data of the calling terminal to terminals within a coverage range thereof using the first frequency in a fourth time slot of each frame, which may include:
s141, each of the transfer devices modulates the data of the calling terminal to obtain modulated data.
Each relay device modulates the data of the calling terminal, which may include: and determining a time slice allowing the data of the calling terminal to pass, transmitting the data in the time slice allowing the data of the calling terminal to pass, and forbidding the data transmission at the time except the time slice allowing the data of the calling terminal to pass.
The time slice allowing the data of the calling terminal to pass through can be determined by the total number of the transit devices in the target area. Specifically, the number of time slices for allowing the data of the calling terminal to pass is the same as the total number of the transit devices in the target area. For example, if the total number of relay devices in the target area is 3, the number of time slices is 3, and one symbol is divided into 3 time slices (i.e., windows), as shown in fig. 2; if the total number of relay devices in the target area is 6, the number of time slices is 6, as shown in fig. 3.
And S142, each transfer device forwards the modulated data to the terminals in the coverage range of the transfer device by using the first frequency in the fourth time slot of each frame from the target frame.
In this embodiment, each relay device modulates the data of the calling terminal to obtain modulated data, and forwards the modulated data to terminals within the coverage range of the terminal using the first frequency in the fourth time slot of each frame starting from the target frame, so as to reduce inter-symbol interference.
It should be noted that, when one relay device is included in the target area, the relay device selects two time slots from a first time slot, a second time slot, a third time slot and a fourth time slot, and the two time slots are respectively used for receiving data and sending data, and uses a first frequency in the time slot for receiving data, receives data from the calling terminal, and uses the first frequency in the time slot for sending data to forward the data of the calling terminal to the terminals within the coverage range of the calling terminal.
The transfer device in the target area selects at least two time slots from the first time slot, the second time slot and the third time slot, and the two time slots are respectively used for receiving data and sending data, so that the situation that the transfer device cannot transfer the data due to the fact that no idle time slot is available is avoided, and continuous skip among a plurality of transfer devices is guaranteed.
And when at least two transfer devices are included in the target area, each transfer device selects two time slots from the first time slot, the second time slot and the third time slot, and the two time slots are respectively used for receiving data and sending data.
And the relay device receives the data of the terminal by using the first frequency or transmits the data to the terminal by using the first frequency, and transmits and receives the data of the relay device by using the second frequency, so that when the terminal is a common DMO terminal, the terminal can ensure that the data except the voice data transmitted by using the first frequency in the 3 rd time slot does not affect the relay device.
In another embodiment 2 of the present application, which is mainly a refinement of the wireless communication ad hoc network method described in the above embodiment 1, as shown in fig. 4, the method may include, but is not limited to, the following steps:
step S21, when the target area includes at least two relay devices, each relay device selects two time slots from the first time slot, the second time slot and the third time slot, respectively, for receiving data and sending data, and takes the time slot for receiving data as a receiving time slot and the time slot for sending data as a sending time slot;
step S22, the first target relay device in the at least two relay devices uses the first frequency in its receiving time slot to receive the data from the calling terminal, and uses the second frequency in its sending time slot to forward the data of the calling terminal to the relay devices in its coverage area.
In step S23, the other relay devices in the at least two relay devices receive the data from the relay devices using the second frequency in their receiving time slots, and forward the data from the relay devices using the second frequency in their sending time slots.
In this embodiment, the other relay devices in the at least two relay devices receive the data from the relay device using the second frequency in their receiving time slots, and forward the data from the relay device using the second frequency in their sending time slots, which may include but is not limited to:
the other relay devices receive the data from the relay device using the second frequency at the reception time slot of their current frame and forward the data from the relay device using the second frequency at the transmission time slot of their next frame. As shown in fig. 5, the relay device 1 (i.e., the first target relay device) receives data D1 from the calling terminal using the first frequency F1 in the first slot and forwards D1 to the relay device 2 using the second frequency F2 in the third slot, the relay device 2 receives D1 in the 3 rd slot of the 1 st frame, the relay device 2 forwards D1 to the relay device 3 in the second slot of the 2 nd frame, and accordingly, the relay device 3 forwards D1 to the relay device 4 in the first slot of the 3 rd frame.
The detailed procedures of steps S21-S23 can be found in the related descriptions of steps S11-S13 in embodiment 1, and are not repeated herein.
Step S24, each of the relay devices respectively obtains the total number of the relay devices in the target area, and searches for the forwarding frame position corresponding to the total number in the preset correspondence between the number of the relay devices and the forwarding frame position, and takes the frame corresponding to the found forwarding frame position as the target frame.
In this embodiment, the forwarding frame position may be determined according to the total number of the forwarding devices, and specifically, the forwarding frame position in the correspondence relationship is a position where each of the forwarding devices can receive the earliest frame of the data from the calling terminal among the forwarding devices with the number of the forwarding devices.
The correspondence relationship between the preset number of relay devices and the location of the forwarded frame can be seen in table 1.
TABLE 1
In this embodiment, the total number of the relay devices in the target area may be stored in the central server, and each relay device may establish a communication connection with the central server and obtain the number of the relay devices in the target area from the central server. Of course, the number of relay devices in the target area may also be written into each relay device by the wireless device.
And step S25, each of the transit devices forwards the data of the calling terminal to terminals within the coverage area thereof using the first frequency in a fourth time slot of each frame, starting from the target frame.
Steps S24-S25 are a specific implementation of step S14 in example 1.
In this embodiment, the forwarding frame positions corresponding to the total number are searched in the preset correspondence between the number of the forwarding devices and the forwarding frame positions, so that the efficiency of determining the target frame can be improved, and the efficiency of forwarding data to the terminal can be improved.
In another embodiment 3 of the present application, which is mainly an extension of the wireless communication ad hoc network method described in the above embodiment 1, as shown in fig. 6, the method may include, but is not limited to, the following steps:
step S31, when the target area includes at least two relay devices, each relay device selects two time slots from the first time slot, the second time slot, and the third time slot, respectively, for receiving data and sending data, and takes the time slot for receiving data as a receiving time slot and the time slot for sending data as a sending time slot.
The detailed process of step S31 can be referred to the related description of step S11 in embodiment 1, and is not repeated here.
Step S32, the first target relay device in the at least two relay devices uses the first frequency in its receiving time slot to receive the data from the calling terminal, and uses the second frequency to forward the data of the calling terminal to the relay devices in its coverage area in its sending time slot, and uses the first frequency to forward the occupied data in the fourth time slot.
The first target transfer device uses the first frequency to forward the occupied data in the fourth time slot, so that the terminal in the coverage area of the first target transfer device can receive the occupied data by using the first frequency, and when receiving the occupied data, the terminal can determine that the current channel of the first target transfer device is occupied, so that the terminal does not send data at the same time, the situation that multiple terminals call at the same time and cannot normally receive transfer voice is avoided, and meanwhile, the interference on the transfer device is avoided.
Step S33, the other relay devices in the at least two relay devices use the second frequency to receive the data from the relay device in the receiving time slot, use the second frequency to forward the data from the relay device in the sending time slot, and use the first frequency to forward the occupied data in the fourth time slot.
And other transfer equipment uses the first frequency to forward the occupied data in the fourth time slot, so that terminals in the coverage range of other transfer equipment can receive the occupied data by using the first frequency, and when the terminals receive the occupied data, the terminals can determine that the current channel of the first target transfer equipment is occupied, so that the terminals can not send data at the same time any more, the calling of multiple terminals at the same time is avoided, the transfer voice can not be normally received, and meanwhile, the interference to the transfer equipment is avoided.
Step S34, each of the relay devices forwards the data of the calling terminal to the terminals within its coverage area using the first frequency in the fourth time slot of each frame, starting from a target frame, where the target frame is the earliest frame in which each of the relay devices can receive the data from the calling terminal.
