Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0048] In this exemplary embodiment, a communication path establishment method is first provided, which can be run on a terminal device; of course, those skilled in the art can also run the method of the present invention on other platforms as required, which is not particularly limited in this exemplary embodiment. Figure 1 As shown, the communication path establishment method may include step S110 and step S120:

[0049] Step S110. In the first multi-hop communication path between the first terminal device and the second terminal device, when communication interruption occurs in the relay terminal device, a path reselection notification is generated;

[0050] Step S120: Send the path reselection notification to the first terminal device, so that the first terminal device creates a second multi-hop communication path according to the path reselection notification.

[0051] In the above communication path establishment method, when a communication interruption occurs in a relay terminal device in a first multi-hop communication path between a first terminal device and a second terminal device, a path reselection notification is generated; the path reselection notification is sent to the first terminal device, so that the first terminal device creates a second multi-hop communication path according to the path reselection notification. When a communication interruption occurs in the first multi-hop communication path, the relay terminal device sends a path reselection notification to the first terminal device, and the first terminal device establishes a second multi-hop communication path according to the path reselection notification, which solves the problem in the related art that when a communication interruption occurs, the relay terminal performs path reselection, thereby affecting the communication service, realizes the selection of the optimal path, and reduces the impact on the communication service.

[0052] Hereinafter, each step involved in the communication path establishment method according to the exemplary embodiment of the present disclosure is explained and illustrated in detail.

[0053] First, the application scenario and purpose of the example embodiment of the present disclosure are explained and illustrated. Specifically, the example embodiment of the present disclosure can be applied to when a first terminal device and a second terminal device establish a first multi-hop communication path. When the communication path between any relay terminal device and its next-hop relay terminal device in the first multi-hop communication path is interrupted, the relay terminal device makes a judgment and generates a path reselection notification, and sends the path reselection notification to the first terminal device, and the first terminal device creates a second multi-hop communication path according to the path reselection notification. This solves the problem in the related art that when the first multi-hop communication path is interrupted, the relay terminal device may have a new communication path with more hops or no available path can be selected when performing path reselection, thereby affecting the communication service.

[0054] Next, step S110 and step S120 are explained and illustrated in detail.

[0055] In step S110, when communication interruption occurs in a relay terminal device in a first multi-hop communication path between a first terminal device and a second terminal device, a path reselection notification is generated.

[0056] In this example embodiment, a first terminal device communicates with a second terminal device, and a communication path between the first terminal device and the second terminal device includes multiple relay terminal devices, and a first multi-hop communication path is generated through the multiple relay terminal devices. In the first multi-hop communication path, when a communication interruption occurs in a relay device, the relay device generates a path reselection notification. The communication interruption of the relay terminal device includes:

[0057] In a first multi-hop communication path between the first terminal device and the second terminal device, a communication path between the relay terminal device and a relay terminal device at a next hop of the relay terminal device is unavailable.

[0058] Specifically, when the communication path between any relay terminal device in the first multi-hop communication path and the next-hop relay terminal device of the relay terminal device is unavailable, it is confirmed that the communication between the relay terminal device and the next-hop relay terminal device of the relay terminal device is interrupted. The unavailable communication path may mean that the communication link between the relay terminal device and the next-hop relay terminal device does not exist, and the unavailable communication path is not specifically limited in this example embodiment.

[0059] In this example embodiment, the terminal device may further include:

[0060] In a first multi-hop communication path between the first terminal device and the second terminal device, a communication connection between the relay terminal device and the second terminal device is unavailable.

[0061] Specifically, in the first multi-hop communication path, when the communication connection between any relay terminal device and the next-hop relay terminal device of the relay terminal device is unavailable, it is confirmed that the communication between the relay terminal device and the next-hop relay terminal device of the relay terminal device is interrupted. The unavailable communication connection may be poor link signal quality between the relay terminal device and the next-hop relay terminal device. In this example embodiment, the unavailable communication connection is not specifically limited.

[0062] In this exemplary embodiment, when communication interruption occurs in the relay terminal device in the first multi-hop communication path between the first terminal device and the second terminal device, generating a path reselection notification includes:

[0063] When the communication path between the relay terminal device and the second terminal device satisfies the path reselection reason, the path reselection notification is generated.

[0064] Specifically, when communication is interrupted between a relay terminal device and its next-hop relay terminal device in the first multi-hop communication path, the relay terminal device determines the communication path between it and the second terminal device to confirm whether the communication path between the relay terminal device and the second terminal device satisfies the path reselection reason. If so, the relay terminal device generates a path reselection notification based on the path reselection reason.

[0065] Furthermore, the reason for the path reselection is that there is no third multi-hop communication path between the relay terminal device and the second terminal device, or the number of hops included in the third multi-hop communication path between the relay terminal device and the second terminal device is greater than the number of hops between the relay terminal device and the second terminal device in the first multi-hop communication path.

[0066] Specifically, when the communication path between the relay terminal device and the relay terminal device at its next hop is interrupted, the relay terminal device determines whether there is a third multi-hop communication path between it and the second terminal device. When there is no third multi-hop communication path, the relay terminal device generates a path reselection notification; when there is a third multi-hop communication path, but the number of hops included in the third communication path is greater than the number of hops between the relay terminal device and the second terminal device in the first multi-hop communication path, the relay terminal device generates a path reselection notification.

[0067] For example, refer to Figure 2 The communication path diagram shown in the figure includes relay terminal device 1, relay terminal device 2 and relay terminal device 3 in the communication path between the first terminal device and the second terminal device. When the communication path between relay terminal device 2 and relay terminal device 3 is unavailable, there is a third multi-hop communication path between relay terminal device 2 and the second terminal device, which is composed of relay terminal device 6, relay terminal device 5 and relay terminal device 7. However, the number of hops included in the third multi-hop communication path is more than the number of hops between the relay terminal device and the second terminal device in the first multi-hop communication path. At this time, relay terminal device 2 generates a path reselection notification.

[0068] In step S120, the path reselection notification is sent to the first terminal device, so that the first terminal device creates a second multi-hop communication path according to the path reselection notification.

[0069] When the relay terminal device generates a path reselection notification, the path reselection notification can be sent to the first terminal device. When sending it to the first terminal device, the path reselection notification can be first sent to the previous-hop relay terminal device of the relay terminal device according to the first multi-hop communication path, and then the path reselection notification can be sent to the first terminal device through the previous-hop relay terminal device of the relay terminal device.

[0070] In this example embodiment, sending the path reselection notification to the first terminal device includes:

[0071] The path reselection notification is sent to the previous-hop relay terminal device of the relay terminal device in the first multi-hop communication path, and when the fourth multi-hop communication path between the previous-hop relay terminal device and the second terminal device meets the path reselection reason, the path reselection notification is sent to the first terminal device.

[0072] Specifically, the relay terminal device sends a path reselection notification to the previous relay terminal device of the relay terminal device in the first multi-hop communication path. When the previous relay terminal device receives the path reselection notification, it determines the communication path between it and the second terminal device. When the fourth communication path between the previous relay terminal device and the second terminal device meets the path reselection reason, the previous relay terminal device sends a path reselection notification to the first terminal device. The path reselection reason is that there is no fourth multi-hop communication path between the previous relay terminal device and the second terminal device, or the number of hops included in the fourth multi-hop communication path between the previous relay terminal device and the second terminal device is greater than the number of hops between the previous relay terminal device and the second terminal device in the first multi-hop communication path.

[0073] Specifically, the reason for path reselection satisfied by the communication path between the previous-hop relay terminal device and the second terminal device may be that there is no fourth multi-hop communication path between the previous-hop relay terminal device and the second terminal device, or there is a fourth multi-hop communication path between the previous-hop relay terminal device and the second terminal device, but the number of hops included in the fourth multi-hop communication path is greater than the number of hops between the previous-hop relay terminal device and the second terminal device in the first multi-hop communication path.

[0074] For example, refer to Figure 2 In the communication path diagram shown, when the communication path between the relay terminal device 2 and the relay terminal device 3 is interrupted, and the third multi-hop communication path between the relay terminal device 2 and the second terminal device meets the path reselection reason, at this time, the relay terminal device 2 sends a path reselection notification to the relay terminal device 1. After the relay terminal device 1 receives the path reselection notification, there is a fourth multi-hop communication path between the relay terminal device 1 and the second terminal device consisting of the relay terminal device 4, the relay terminal device 5, and the relay terminal device 7. In the fourth multi-hop communication path, the number of hops between the relay terminal device 1 and the second terminal device is greater than the number of hops between the relay terminal device 1 and the second terminal device in the first multi-hop communication path. Then, the relay terminal device 1 sends the received path reselection notification to the first terminal device.

[0075] In this example embodiment, the path reselection notification includes a path reselection reason. When the first terminal device receives the path reselection notification, it reestablishes the second multi-hop communication path with the second terminal device according to the path reselection reason included in the path reselection notification.

[0076] In this exemplary embodiment, a communication path establishment method is also provided, which is applied to a first terminal device, and the communication path establishment method includes:

[0077] A path reselection notification sent by a relay terminal device in a first multi-hop communication path is received, and a second multi-hop communication path with a second terminal device is established based on the path reselection notification.

[0078] Specifically, after the first terminal device and the second terminal device have established a first multi-hop communication path, when the communication path between the relay terminal device in the first multi-hop communication path and its next-hop relay terminal device is interrupted, the relay terminal device determines whether the third communication path to the second terminal device satisfies the path reselection reason. If so, the relay terminal device generates a path reselection notification based on the path reselection reason satisfied by the relay terminal device, and sends the path reselection notification to the first terminal device. The first terminal device receives the path reselection notification sent by the relay terminal device, and establishes a second multi-hop communication path with the second terminal device according to the path reselection notification.

[0079] In this exemplary embodiment, the receiving a path reselection notification sent by a relay terminal device in the first multi-hop communication path includes:

[0080] Receive the path reselection notification sent by a relay terminal device located at the next hop of the first terminal device in the first multi-hop communication path.

[0081] Specifically, after the relay terminal device generates a path reselection notification, it sends the path reselection notification to the relay terminal device located at the previous hop in the first multi-hop communication path, and the previous hop relay terminal device sends the path reselection notification to the previous hop relay terminal device of the previous hop relay terminal device, and finally the next hop relay terminal device of the first terminal device sends the path reselection notification to the first terminal device.

[0082] In this example embodiment, the path reselection notification received by the first terminal device includes a path reselection reason, and the path reselection reason is that there is no third multi-hop communication path between the relay terminal device and the second terminal device or the number of hops included in the third multi-hop communication path between the relay terminal device and the second terminal device is greater than the number of hops between the relay terminal device and the second terminal device in the first multi-hop communication path.

[0083] Specifically, when the relay terminal device determines that the communication path between it and the second terminal device satisfies the path reselection reason, the relay terminal device generates a path reselection notification according to the path reselection reason, that is, the path reselection notification includes the path reselection reason of the relay terminal device for generating the path reselection notification, wherein the path reselection reason may be that there is no communication path between the relay terminal device and the second terminal device, or that there is a communication path between the relay terminal device and the second terminal device, but the number of hops included in the communication path is greater than the number of hops between the relay terminal device and the second terminal device in the first multi-hop communication path.

[0084] In this exemplary embodiment, the reason for path reselection is that the relay terminal device exits the relay service.

[0085] Specifically, in the first multi-hop communication path between the first terminal device and the second terminal device, when any relay terminal device exits the relay service, the communication path between the relay terminal device and the second terminal device meets the path reselection reason. At this time, the relay terminal device generates a path reselection notification.

[0086] The communication path establishment method provided by the example embodiment of the present disclosure has at least the following advantages: when a communication interruption occurs in the first multi-hop communication path, the relay terminal device sends a path reselection notification to the first terminal device, and the first terminal device establishes a second multi-hop communication path according to the path reselection notification, thereby solving the problem in the related art that when a communication interruption occurs, the relay terminal reselects the path and thus affects the communication service, thereby achieving the selection of the optimal path and reducing the impact on the communication service.

[0087] The exemplary embodiment of the present disclosure also provides a communication path establishment device, referring to Figure 3 As shown, it may include: a path reselection notification generating module 310 and a path reselection notification sending module 320. Among them:

[0088] A path reselection notification generating module 310, configured to generate a path reselection notification when a communication interruption occurs to a relay terminal device in a first multi-hop communication path between a first terminal device and a second terminal device;

[0089] The path reselection notification sending module 320 is used to send the path reselection notification to the first terminal device, so that the first terminal device creates a second multi-hop communication path according to the path reselection notification.

[0090] The exemplary embodiment of the present disclosure also provides a communication path establishment device, referring to Figure 4 As shown, it may include: a path reselection notification receiving module 410. Among them:

[0091] The path reselection notification receiving module 410 is used to receive a path reselection notification sent by a relay terminal device in a first multi-hop communication path, and establish a second multi-hop communication path with a second terminal device based on the path reselection notification.

[0093] In an exemplary embodiment of the present disclosure, the relay terminal device has a communication interruption, including:

[0097] In an exemplary embodiment of the present disclosure, when communication interruption occurs in a relay terminal device in a first multi-hop communication path between a first terminal device and a second terminal device, generating a path reselection notification includes:

[0098] When the communication path between the relay terminal device and the second terminal device satisfies the path reselection reason, the path reselection notification is generated.

[0102] In an exemplary embodiment of the present disclosure, the reason for the path reselection is that there is no fourth multi-hop communication path between the previous-hop relay terminal device and the second terminal device, or the number of hops included in the fourth multi-hop communication path between the previous-hop relay terminal device and the second terminal device is greater than the number of hops between the previous-hop relay terminal device and the second terminal device in the first multi-hop communication path.
