Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

It is to be noted that unless otherwise defined, technical or scientific terms used in one or more embodiments of the present application should be taken in a general sense as understood by one of ordinary skill in the art to which the present application belongs. The use of the terms "first," "second," and the like in one or more embodiments of the present application does not denote any order, quantity, or importance, but rather the terms "first," "second," and the like are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that elements or items preceding the word are included in the element or item listed after the word and equivalents thereof, but does not exclude other elements or items. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

In the related art, in the field of communications, network devices and user terminal devices having data forwarding and processing capabilities implement link interconnection, if a data channel, particularly a wireless data channel, fails under conditions of wireless link fluctuation, electromagnetic interference, electronic countermeasure, and the like, data interaction cannot be performed, so that it is generally required to check reliability or communication status of the data channel, that is, sense a link of a reliable data channel. The weak link (unstable narrowband) has the characteristics of poor channel quality, high error rate, narrow bandwidth and the like, such as microwave links, satellite links and the like. Data transfer over a weak connection (unstable narrowband) link first requires confirmation of connection establishment and maintenance between the sender and receiver, and second considers that data is transferred as quickly and efficiently as possible under limited bandwidth conditions.

The link sensing technology is a technology for sensing the link state, and can use signaling packets to measure the link state such as on-off, congestion, available bandwidth and the like of the link.

During end-to-end communication, data packets may be communicated directly between a sender and a receiver, or may be relayed through other network devices.

The existing scheme I is as follows: and realizing the link on-off sensing by adopting a heartbeat detection mode, as shown in figure 1. Node 1 and node 2 may be user devices or network devices. The node 1 periodically sends a connection request signaling packet to the neighboring node 2, and the node 2 immediately returns a connection acknowledgement signaling packet to the node 1 after receiving the connection request signaling. If node 1 can receive the connection confirmation signaling packet within the appointed time, the link between node 1 and node 2 is reachable, otherwise, the link is interrupted.

The existing scheme II: link congestion awareness and data transfer are implemented using the TCP protocol, as shown in fig. 2. The TCP protocol is a reliable transport protocol that uses a three-way handshake protocol to establish a connection. Firstly, user equipment 1 sends SYN signaling packets to user equipment 2; the user equipment 2 receives the SYN message and responds to a SYN-ACK signaling packet to the user equipment 1; after receiving the SYN-ACK signaling packet of the user equipment 2, the user equipment 1 responds an ACK signaling packet to the user equipment 2; after the three-way handshake is successful, the connection is established and data transfer can begin. During the data transfer process, the user equipment 1 sends a data packet with a sequence number to the user equipment 2, and when the user equipment 2 receives a data packet, the user equipment determines whether the data packet is the data packet to be received according to the currently received sequence number. If the user equipment 2 determines that the data packet is received correctly, a data acknowledgement packet is returned to the user equipment, otherwise, a data error packet is not replied or returned. When the user equipment 1 receives the data confirmation packet from the user equipment 2 within a certain time, the link connection between the two is considered to be normal; otherwise, if the data confirmation packet is not received or the data error packet is received, the link is considered to have the conditions of interruption, congestion or packet loss.

The disadvantage of scheme one:

1. The on-off of the link is perceived by sending independent heartbeat detection signaling packets, so that extra overhead is brought, and part of link bandwidth is occupied, so that the method is not suitable for a narrow-band link scene.

2. The existing scheme can only detect the on-off state of the link, but cannot sense other states of the link, including congestion, packet loss and the like.

3. The existing scheme is only used for link connection detection and does not have a data transfer function.

Scheme two has the disadvantage:

1. Before data transmission, a three-way handshake mode based on a TCP protocol is needed to establish connection between user equipment, the connection establishment time is long, and a large amount of extra time delay is brought.

2. The state of the link is indirectly perceived by using the data confirmation packet in the data transmission process, but the method is only used for judging the state of the end-to-end link between user equipment, and when one or more network equipment exists in the middle, the state of the middle segment link cannot be judged in a distinguishing way, and when the data packet is lost, the data packet must be retransmitted from a transmitting end, and data retransmission overhead is brought to the whole link, so that the bandwidth of the whole link is occupied.

Under the condition of weak connection (unstable narrow band) link, the problems of how to sense the on-off state of the link, save very limited link bandwidth resources as much as possible, and deliver data successfully as soon as possible under the condition that the link is available exist.

The application provides a state sensing transmission method for a weak connection link, which uses a small data packet bearing a payload to sense on-off of the link, and transmits data to the other party when sensing the communication of the link.

In order to prevent data errors caused by unstable links, the data load part uses error correction codes, and data verification and error correction can be completed after the data is received.

The small data packet uses a serial number, and the receiving party sends confirmation information to the data packet passing the verification after receiving the small data packet.

The sender uses a timeout mechanism and resends small packets that have not received an acknowledgement after a timeout.

If one or more other network devices pass through between the sending end and the receiving end, link sensing and data transmission are carried out in a hop-by-hop buffer confirmation mode.

Various non-limiting embodiments of the present application are described in detail below with reference to the attached drawing figures.

First, a state aware transmission method for a weak link according to the present application will be described in detail with reference to fig. 3:

As shown in fig. 3, the present application provides a state aware transmission method for a weak link, including:

The first user device may be a terminal device, such as a mobile phone, a computer, etc.

the first user equipment acquires a payload;

Illustratively, the payload is split into 10 fragments, 10 being an example here, and a person skilled in the art can make a determination according to the actual situation. Wherein segment 1 corresponds to error correction code 1, segment 2 corresponds to error correction code 2, and so on. Combining each segment with its corresponding error correction code to obtain a corresponding link-aware small packet, e.g., link-aware small packet 1, link-aware small packets 2, …, link-aware small packet 10, etc. may be obtained; each link aware small packet corresponds to sequence numbers 1 to 10, respectively.

The second device may be a network device, or may be a terminal device, and the third device may be a network device, or may be a terminal device. The setting can be performed according to actual requirements.

the second equipment receives N link perception small data packets;

For example, N may be an integer such as 2/3/4, and is not specifically shown here, and may be set according to actual circumstances.

The state-aware transmission method for weak link according to the present application is described in detail below by way of example 1:

The state sensing transmission method for the weak link in this embodiment adopts a small data packet with an error correction code and carrying a payload as a sensing packet for sensing the on-off state of the link (i.e., a link sensing small data packet), and specifically includes:

The first user equipment splits the payload into small data fragments and calculates error correction codes for the split data fragments, and then encapsulates the data fragments and error correction codes together in a link aware packet.

The first user equipment maintains the sequence number of the sensing packet, puts the sequence number in the sensing packet, and sends the sensing packet with the sequence number to the second user equipment at a certain period (namely, a sending interval).

After the second user equipment receives the sensing packet sent by the first user equipment, the second user equipment detects and corrects errors of the valid data fragments in the sensing packet, and if the valid data fragments are correct, a confirmation message with a serial number is replied to the first user equipment.

If the error correction is unsuccessful, the second user equipment returns a negative acknowledgement message with a sequence number to the first user equipment.

If the first user equipment receives the confirmation message of the second user equipment, the corresponding data segment is recorded, the network state is judged to be good, the sending interval (for example, a target sending interval is adopted) is reduced, and the data segment with the error correction code is continuously sent to the second user equipment.

And if the first user equipment receives the negative acknowledgement message of the second user equipment, resetting the transmission interval to a default period (namely a default transmission interval) and retransmitting the data segment corresponding to the sequence number.

Further, if there are one or more other network devices between the first user device and the second user device, network-aware packets carrying valid data segments are transmitted hop-by-hop between each hop, error correction acknowledgements, and buffered for re-forwarding.

Further, the second ue may piggyback the acknowledgement or negative acknowledgement message of the plurality of data packets in one acknowledgement/negative acknowledgement packet after continuously receiving the plurality of small data packets.

Further, the sender uses a timeout mechanism, and the small data packet which does not receive the acknowledgement after timeout is retransmitted.

The state sensing transmission method for the weak link provided by the embodiment is oriented to the communication requirement under the weak link (unstable narrow band), and solves the problem of occupation of link bandwidth by link on-off sensing, so that data transmission is completed as soon as possible when the link under the weak link (unstable narrow band) is available.

Another embodiment of the present application is described in detail below with reference to fig. 4:

As shown in fig. 4, in the end-to-end communication process, the method adopts a hop-by-hop transmission mode to perform sensing of a link state and data transmission, and in order to support sensing of the link state and effective data transmission, three groups, namely a sensing data group, an acknowledgement group and a denial group, are adopted. The perceptual packet comprises at least a data fragment, an error correction code and a sequence number. The acknowledgement packet or the negative acknowledgement packet includes at least a sequence number.

End-to-end communication is carried out between the first user equipment and the second user equipment, and the communication is carried out through the first network equipment. The first user equipment encapsulates the effective data fragments and the error correction code into a link aware small data packet with a sequence number of 1, and sends the link aware small data packet to the first network equipment. After receiving the link perception small data packet with the sequence number of 1, the first network equipment checks and corrects the data fragment in the link perception small data packet; after the verification is passed, the first network equipment caches the sensing packet with the sequence number of 1, and replies a confirmation message with the sequence number of 1 to the first user equipment; meanwhile, the first network device forwards the cached perceived packet with the sequence number of 1 to the second user device.

After receiving the acknowledgement message with the sequence number of 1 of the first network device, the first user device determines that the link state is good, reduces the transmission interval (for example, adopts a target transmission interval), and continuously transmits the link perception small data packets with the sequence numbers of 2, 3 and 4 to the first network device. And after the first network equipment receives the link perception small data packets with the sequence numbers of 2, 3 and 4, respectively checking and correcting errors. The data packets with the sequence numbers of 2 and 3 pass the verification and are cached in the first network equipment; the data packet with the sequence number of 4 is not checked and error correction is not successful, the first network device replies a negative acknowledgement message with the sequence number of 4 to the first user device, and acknowledgement messages with the sequence numbers of 2 and 3 are piggybacked in the message.

The first network device forwards small data packets with sequence numbers of 2 and 3 to the second user device.

After receiving the denial message with the sequence number of 4, the first user equipment acquires that the data packet with the sequence number of 4 fails to be sent, and acquires that the data packets with the sequence numbers of 2 and 3 are successfully sent. The first user equipment retransmits the data packet with the sequence number of 4 to the first network equipment.

The state sensing transmission method for the weak link can realize the following technical effects:

1. the small data packet carrying the effective load is used as a sensing packet for sensing the on-off state of the link, and the limited link bandwidth resource is utilized to transfer data while the on-off state of the link is sensed, so that no extra signaling overhead is caused.

2. The payload is split into small data fragments to reduce bandwidth occupation and data packet retransmission overhead.

3. The technology of hop-by-hop transmission and buffer forwarding is utilized to realize the segmentation state sensing of each section of link between the transmitting user equipment and the receiving user equipment, and realize the segmentation retransmission of the data packet under the condition of data packet loss or abnormal link connection, thereby avoiding the retransmission overhead of the whole link.
