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 invention.

Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.

Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the 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 explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The Mobile terminal according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various forms of User Equipment (UE), Mobile Stations (MS), terminal devices (terminal device), and the like. For convenience of description, the above-mentioned devices are collectively referred to as a mobile terminal.

The following describes embodiments of the present application in detail.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture of a Lora network disclosed in an embodiment of the present application, where the Lora network includes Lora nodes such as a first Lora device, a second Lora device, a third Lora device, a Lora gateway, a network server, and an application server. Among them, the Lora device in the Lora network modulates the physical layer (PHY), so that the Lora device can also be used for different protocols and different network architectures (such as Mesh, Star, point-to-point, etc.).

Long range (Lora), also called long distance, is a low power consumption local area network wireless standard (IEEE 802.15.4 g). The working frequency is ISM (Industrial Scientific medical) frequency band, which may include 433MHz, 868MHz, 915MHz, etc.

The Lora device can access the network server and/or the application server through the Lora gateway or other Lora devices with the relay function. The communication distance of the Lora equipment is generally several kilometers to tens of kilometers, and compared with the Bluetooth communication and the WiFi communication, the communication distance of the Lora equipment is farther.

The Lora device may include a Lora module (e.g., a Lora chip), where the Lora chip may support not only a spread spectrum modulation manner, but also other multiple standard modulation manners such as Frequency-shift Keying (FSK)/gaussian Frequency-shift Keying (GFSK), and may be switched to each other, thereby implementing a remote modulation capability and using a standard FSK or binary On-Off Keying (OOK) modulation technique. The Lora device may be any mobile terminal including the Lora module, such as a cell phone, a wearable device (e.g., a smart band, a smart watch, a smart headset, etc.), a tablet computer, and the like.

If the Lora gateway closest to the Lora equipment is in a place dozens of kilometers or even farther, the Lora equipment cannot be directly connected with the Lora gateway, and can be connected with the Lora gateway through other nearby Lora equipment with a relay function. For example, in outdoor activities such as traversing and mountain climbing, if a target Lora device is far away from a nearest Lora gateway (for example, greater than 20 kilometers) and the target Lora device needs to access a network server or an application server, the target Lora device may plan a path to the nearest Lora gateway and initiate a relay application request to all other Lora devices on the path, and when all other Lora devices on the path are not in a relay transmission state and the priority of the target Lora device meets a lowest priority threshold required by all other Lora devices on the path, all other Lora devices on the path allow the target Lora device to perform relay transmission.

In the embodiment of the application, when the Lora device performs relay transmission, the priority of the Lora device initiating the application needs to be judged, and the Lora device with lower priority is prevented from performing relay transmission, so that the relay transmission safety of the Lora device can be improved.

Based on the network architecture shown in fig. 1, the embodiment of the application discloses a relay transmission method. Referring to fig. 2, fig. 2 is a flowchart illustrating a relay transmission method according to an embodiment of the present disclosure, and as shown in fig. 2, the relay transmission method includes the following steps.

201, a first Lora device receives a first relay application request sent by a second Lora device.

In this embodiment of the present application, the first Lora device and the second Lora device both belong to Lora nodes in the Lora network. The first Lora device and the second Lora device may both support a relay function, that is, signals transmitted between two or more Lora devices may be relayed by using other Lora devices.

When the second Lora device needs to access the network server and/or the application server, if the second Lora device is located in a remote place outdoors, the second Lora device cannot be directly connected with the Lora gateway, and can be connected with the Lora gateway through other nearby Lora devices with relay functions. Specifically, the second Lora device may plan at least one access path according to distribution of the Lora network architecture, the second Lora device may select an optimal access path from the at least one access path, and the second Lora device sends the first relay application request to other Lora nodes on the optimal access path. The first relay application request may carry at least one of an equipment identifier of the second Lora equipment, a group identifier of a group to which the second Lora equipment joins, and an identity identifier of the second Lora equipment.

202, the first Lora device determines a priority of the second Lora device.

In this embodiment of the present application, the first Lora device may determine the priority of the second Lora device according to the device identifier of the second Lora device, the group identifier of the group to which the second Lora device joins, the identity identifier of the second Lora device, and the communication frequency between the second Lora device and the first Lora device. In general, the higher the communication frequency of the second Lora device with the first Lora device, the higher the priority of the second Lora device.

Alternatively, the first Lora device may determine the priority of the second Lora device according to the following formula:

P＝a1*X+a2*Y+a2*Z+a4*W；

wherein, X is a priority weight corresponding to the device identifier of the second Lora device, Y is a priority weight corresponding to the group identifier of the group to which the second Lora device joins, Z is a priority weight corresponding to the identity identifier of the second Lora device, and W is a priority weight corresponding to the communication frequency of the second Lora device and the first Lora device; a1, a2, a3 and a4 are corresponding weight coefficients; p is the priority of the second Lora device.

The memory (e.g., the nonvolatile memory) of the first Lora device may store a Lora device list, where the Lora device list includes a correspondence between an Lora device identifier and a corresponding priority weight, a correspondence between a group identifier of a group joined by the Lora device and a corresponding priority weight, a correspondence between an identity identifier of the Lora device and a corresponding priority weight, and a communication record between the Lora device and the first Lora device.

For example, the corresponding relationship between the Lora device identifier and the corresponding priority weight can be seen in table 1.

TABLE 1

Lora equipment identification	Priority weight
		Lora equipment A	X1
Lora equipment B	X2
		Lora equipment C	X3
Lora device D	X4
		Lora equipment E	X5

As shown in table 1, the priority weights corresponding to different Lora device identifiers may be the same or different, and the priorities of the Lora device identifiers may be preset and stored in the memory of the first Lora device. For example, if the Lora device identifier carried in the relay application request received by the first Lora device is Lora device a, the corresponding priority weight is X1; if the Lora equipment identifier carried in the relay application request received by the first Lora equipment is Lora equipment B, the corresponding priority weight is X2; if the Lora device identifier carried in the relay application request received by the first Lora device is the Lora device C, the corresponding priority weight is X3; if the Lora device identifier carried in the relay application request received by the first Lora device is the Lora device D, the corresponding priority weight is X4; if the Lora device identifier carried in the relay application request received by the first Lora device is the Lora device E, the corresponding priority weight is X5. Wherein, X1, X2, X3, X4 and X5 are all positive values, and the larger the weight value is, the higher the priority is. If the Lora device identifier carried in the relay application request received by the first Lora device is not any one of Lora device A, Lora device B, Lora device C, Lora device D, Lora device E, the corresponding priority weight defaults to 0.

For example, the correspondence between the group identifier of the group joined by the Lora device and the corresponding priority weight can be seen in table 2.

TABLE 2

Group identification of group joined by Lora device	Priority weight
		Group identification A	Y1
Group identification B	Y2
		Group identification C	Y3
Group identification D	Y4
		Group identifier E	Y5

As shown in table 2, the priority weights corresponding to the group identifiers of the groups joined by different Lora devices may be the same or different. If the group identifier of the group to which the first Lora device currently joins is the group identifier a, the group identifiers of the group to which the first Lora device historically joins are the group identifier B, the group identifier C, the group identifier D, and the group identifier E, respectively. The weight of Y1 is greater than any of Y2, Y3, Y4, and Y5. For the priority weight corresponding to the group identifier of the group which is historically added, the first Lora device may comprehensively determine the priority weight corresponding to the group identifier of the group which is historically added according to the communication record of the group which is historically added, the accumulated duration of group addition, and the time point of group addition. The priority weight corresponding to the group identifier of the group which is added in the history is positively correlated with the communication record of the group which is added in the history and the accumulated time length of the group which is added in the history. Generally, the longer the accumulated time of the group joined historically, the closer the time point of the group joined historically and the current time, and the more the communication records of the group joined historically, the greater the priority weight corresponding to the group identifier of the group joined historically. Y1, Y2, Y3, Y4 and Y5 are all positive values, and the larger the weight value is, the higher the priority is. If the group identifier of the group to which the Lora device joins, which is carried in the relay application request received by the first Lora device, is not any one of the group identifier a, the group identifier B, the group identifier C, the group identifier D, and the group identifier E, the corresponding priority weight is defaulted to 0.

For example, the correspondence between the identity of the Lora device and the corresponding priority weight can be seen in table 3.

TABLE 3

Identity of Lora equipment	Priority weight
		Lora identity A	Z1
Lora identity B	Z2
		Lora identity C	Z3
Lora identification D	Z4
		Lora identity E	Z5

As shown in table 3, the priority weights corresponding to the identifiers of different Lora devices may be the same or different, and the priorities of the identifiers of the Lora devices may be preset and stored in the memory of the first Lora device. For example, the priority corresponding to the Lora identity a is Z1, the priority corresponding to the Lora identity B is Z2, the priority corresponding to the Lora identity C is Z3, the priority corresponding to the Lora identity D is Z4, and the priority corresponding to the Lora identity E is Z5. Wherein, Z1, Z2, Z3, Z4 and Z5 are all positive values, and the larger the weight value is, the higher the priority is. If the identity of the Lora device carried in the relay application request received by the first Lora device is not any one of the identity E of the Lora identity A, Lora identity B, Lora identity C, Lora identity D, Lora identity, the corresponding priority weight is defaulted to 0.

For example, the correspondence between the communication frequencies of the Lora device and the first Lora device and the corresponding priority weights may be shown in table 4.

TABLE 4

Lora equipment identification	Communication frequency with first Lora device	Priority weight
			Lora equipment A	F1	W1
Lora equipment B	F2	W2
			Lora equipment C	F3	W3
Lora device D	F4	W4
			Lora equipment E	F5	W5

As shown in table 4, the communication frequency between the Lora device a and the first Lora device is F1, the corresponding priority weight is W1, the communication frequency between the Lora device B and the first Lora device is F2, the corresponding priority weight is W2, the communication frequency between the Lora device C and the first Lora device is F3, the corresponding priority weight is W3, the communication frequency between the Lora device D and the first Lora device is F4, the corresponding priority weight is W4, the communication frequency between the Lora device E and the first Lora device is F5, and the corresponding priority weight is W5. The priority weights corresponding to the communication frequencies of different Lora devices and the first Lora device may be the same or different. Wherein, the higher the communication frequency, the higher the corresponding priority weight. W1, W2, W3, W4 and W5 are all positive values, and the larger the weight value is, the higher the priority is. If the Lora device identifier carried in the relay application request received by the first Lora device is not any one of Lora device A, Lora device B, Lora device C, Lora device D, Lora device E, the communication frequency between the corresponding Lora device and the first Lora device is 0, and the priority weight is 0.

It should be noted that the priority calculation formula P ═ a1 × X + a2 × Y + a2 × Z + a4 × W is only one possible implementation manner for calculating the priority of the Lora device, and other priority calculation formulas may be provided, and the embodiment of the present application is not limited.

Optionally, the first relay application request carries a group identifier of a group to which the second Lora device joins, and step 202 may specifically include the following steps:

(11) the first Lora equipment verifies whether the group identification of the group joined by the second Lora equipment is consistent with the group identification of the group joined by the first Lora equipment;

(12) and if the group identifier of the group which the second Lora equipment joins is consistent with the group identifier of the group which the first Lora equipment joins, the first Lora equipment determines that the priority of the second Lora equipment is greater than a preset priority threshold.

In this embodiment of the present application, when the first relay application request carries the group identifier of the group to which the second Lora device joins, the first Lora device may determine whether the priority of the second Lora device is greater than the preset priority threshold according to whether the group identifier of the group to which the second Lora device joins is consistent with the group identifier of the group to which the first Lora device joins. Because the group is added in advance, the priority judging mode is simple and effective, only the priority of the Lora equipment in the group is allowed to be greater than the preset priority threshold value, namely, only the Lora equipment in the group is allowed to carry out relay transmission, and the Lora equipment in the group has priority during relay transmission, so that the reliability of data relay transmission of the Lora equipment in the group is improved.

Optionally, before performing step 201, the following steps may also be performed:

and performing Lora Mesh networking on the first Lora equipment and the second Lora equipment, and enabling the first Lora equipment and the second Lora equipment to join the same group.

In the implementation of the application, the first Lora device can perform Lora Mesh networking with the plurality of Lora devices, and the devices in the Mesh networking can perform multi-hop transmission in the Mesh networking. For example, please refer to fig. 3, fig. 3 is a schematic diagram of a group relay transmission according to an embodiment of the present application. As shown in fig. 3, the Lora device A, Lora device B, Lora device C is a device that performs Lora Mesh networking, joins the same group, and generates a group id, and the Lora device A, Lora device B, Lora devices C each store a group id and know device ids of each other. Lora device A, Lora device B, Lora device C becomes a buddy, and Lora device A, Lora device B, Lora device C may be used preferentially when relay functionality is set to group personnel, either automatically or manually. Subsequently, if the Lora device a and the Lora device D simultaneously initiate a relay application request to the Lora device B and the Lora device C, a group identifier of a group to be joined carried in the relay application request sent by the Lora device a is the same as a group identifier of a group to be joined by the Lora device B and the Lora device C, and a group identifier of a group to be joined carried in the relay application request sent by the Lora device D is different from a group identifier of a group to be joined by the Lora device B and the Lora device C, the Lora device B and the Lora device C allow the Lora device a to perform relay transmission. The method and the device can allow the Lora equipment joining the same group to have the function of priority relay, and can ensure that the Lora equipment in the same group can better carry out relay transmission.

Optionally, the first relay application request carries the device identifier of the second Lora device, and step 202 may specifically include the following steps:

(21) the first Lora device verifies whether the device identifier of the second Lora device is one of the high-priority device identifier sets;

(22) and if the equipment identifier of the second Lora equipment is one of the high-priority equipment identifier sets, determining that the priority of the second Lora equipment is greater than a preset priority threshold.

In this embodiment of the present application, a high priority device identifier set may be pre-stored in a memory of the first Lora device, and the high priority device identifier set may include at least one Lora device identifier. The first Lora device may determine the high-priority device identifier set according to the historical communication record, or may manually add a new Lora device identifier in the high-priority device identifier set. When the first relay application request carries the device identifier of the second Lora device, the first Lora device may determine whether the priority of the second Lora device is greater than a preset priority threshold according to whether the device identifier of the second Lora device is one of a set of high-priority device identifiers. Because the high-priority device identifier set is determined in advance, the priority judgment mode is simple and effective, only the priority of the Lora devices in the high-priority device identifier set is allowed to be greater than the preset priority threshold, that is, only the Lora devices in the high-priority device identifier set are allowed to perform relay transmission, and the Lora devices in the high-priority device identifier set have priority during relay transmission, so that the reliability of data relay transmission of the Lora devices in the high-priority device identifier set is improved.

And 203, if the priority of the second Lora device is greater than the preset priority threshold and the first Lora device is not in the relay transmission state, allowing the second Lora device to perform relay transmission through the first Lora device.

In the embodiment of the application, in the same time period, one Lora device can only serve as one Lora device to serve as the relay node, and a plurality of Lora devices can serve as the relay node of one Lora device at the same time. For example, both the Lora device a and the Lora device B initiate a relay application request to the Lora device C, and the Lora device C may select one Lora device to provide the relay transmission service for the Lora device according to the priority of the ora device a and the Lora device B. If the first Lora device is in the relay transmission state, the first Lora device cannot continuously provide the relay transmission service for other Lora devices.

Optionally, after step 203 is executed, the following steps may also be executed:

(31) the method comprises the steps that a first Lora device receives a data packet sent by a second Lora device, wherein the data packet carries a group identifier of a group joined by the second Lora device;

(32) and under the condition that the first Lora device verifies that the group identifier of the group joined by the second Lora device is consistent with the group identifier of the group joined by the first Lora device, forwarding the data packet to the next Lora node.

In this embodiment of the application, after the first Lora device allows the second Lora device to perform relay transmission, the data packet sent to the first Lora device by the second Lora device needs to carry the group identifier of the group that the second device joins, so that the first Lora device can identify the data packet sent by the Lora device in the group, and can send the data packet to the next Lora node. And if the data packet sent by the Lora equipment and received by the second Lora equipment does not carry the group identification, or the carried group identification is inconsistent with the group identification of the group added by the second Lora equipment, discarding the data packet without carrying out relay transmission. Optionally, the second Lora device may further prohibit receiving the data packet sent by the Lora device subsequently, so as to avoid being interfered by the Lora device.

In the embodiment of the present application, when other Lora devices apply for relay forwarding to the first Lora device, the priorities of the other Lora devices may be determined, and only when the priorities of the other Lora devices are greater than a certain priority threshold, the other Lora devices are allowed to perform relay transmission through the first Lora device. The lower Lora equipment of priority is prevented from relaying transmission through first Lora equipment to can promote the security that Lora equipment relayed transmission.

Referring to fig. 4, fig. 4 is a schematic flowchart of another relay transmission method disclosed in the embodiment of the present application, and fig. 4 is obtained by further optimizing on the basis of fig. 2. As shown in fig. 4, the relay transmission method includes the following steps.

401, a first Lora device receives a first relay application request sent by a second Lora device, and the first Lora device receives a second relay application request sent by a third Lora device.

402, a first Lora device determines a priority of a second Lora device, and the first Lora device determines a priority of a third Lora device.

403, if the priority of the second Lora device is greater than the preset priority threshold, the priority of the third Lora device is less than the priority of the second Lora device, and the first Lora device is not in the relay transmission state, allowing the second Lora device to perform relay transmission through the first Lora device.

In this embodiment of the present application, if a first Lora device receives, in the same time period, a relay application request sent by a second Lora device and a relay application request sent by a third Lora device, the first Lora device may compare priorities of the second Lora device and the third Lora device, and only the Lora device, which has a higher priority and is greater than a preset priority threshold, of the second Lora device and the third Lora device is allowed to perform relay transmission through the first Lora device. The preset priority threshold may be preset. When two Lora devices initiate a relay application at the same time, the preset priority threshold may be set to 0, that is, the Lora devices with higher priority in the second Lora device and the third Lora device may be allowed to perform relay transmission through the first Lora device.

404, if the priority of the second Lora device is greater than the preset priority threshold, the priority of the third Lora device is greater than the priority of the second Lora device, and the third Lora device is allowed to perform relay transmission through the first Lora device.

In the embodiment of the application, when two Lora devices simultaneously initiate a relay application, the Lora devices with higher priority in the second Lora device and the third Lora device can be allowed to perform relay transmission through the first Lora device. The lower Lora equipment of priority is prevented from relaying transmission through first Lora equipment to can promote the security that Lora equipment relayed transmission.
