Problems solved by technology

For example, the uplink bandwidth required by a single camera can reach 8Mbps. On the one hand, the data transmission capability of a single camera is limited. On the other hand, for mobile communication networks, such as TD-LTE (Time Division Long Term Evolution, time-sharing long-term evolution) The average uplink rate of the current network cell is about 5Mbps, obviously it cannot meet the data transmission requirements of this type of business, which limits the development of similar services to a large extent

Embodiment 1

[0102] An embodiment of the present invention provides a method for end-to-end data transmission by binding multiple underlying data transmission channels (for example, but not limited to LTE (Long Time Evolution, long-term evolution) data cards, etc.), which utilizes multiple data transmission channels The ability of the channel to provide higher data transmission bandwidth to upper-layer applications. The basic principle is to split the original data IP stream into multiple sub-data streams at the data sending end, and encapsulate the original IP data packets into new IP data packets according to a custom protocol, and then transmit them through different underlying data transmission channels. The underlying data transmission channels are independent of each other during transmission; after receiving the data packets at the data receiving end, they are reordered according to the serial numbers of the data packets, and the original data is restored by removing the self-defined...

Embodiment 2

[0114] For the data sent by the data sending end, the data receiving end needs to maintain a receiving cache for each data sending end. For example, to avoid the data sending end occupying the buffer resources of the data receiving end for a long time, the data sending end can send data to the data receiving end through the registration / de-registration process. The client requests / releases cache resources. During specific implementation, the data sending end may send a registration request to the data receiving end when initially powered on or when there is data to be transmitted, requesting the data receiving end to allocate buffer resources for it. The data sending end sends a deregistration message to the data receiving end before standby / shutdown or after the data transmission is completed, and notifies the data receiving end to reclaim the buffer resources allocated to it.

[0115] It should be noted that the registration / de-registration process provided in Embodiment 2 c...

Embodiment 3

[0142] Since a plurality of data transmission channels are used to transmit data in parallel in the embodiment of the present invention, but the data transmission capabilities (such as bandwidth, transmission delay, etc.) of each data channel may be different, in order to ensure that the data packets arrive in order as much as possible, avoiding the rearrangement timer overtime To cause packet loss, the load balancing technology can be used to control the number of data packets allocated by the data sending end for each data transmission channel, allocate more data packets to data transmission channels with large bandwidth, and allocate less data packets to data transmission channels with small bandwidth.

[0143] The load balancing is mainly based on the data transmission quality information of each data transmission channel acquired by the data sending end, which may but not limited to include data transmission delay and channel quality information of the data transmission cha...

Abstract

The invention discloses a data transmitting and receiving method, a device and a data transmission system, wherein the data transmission requirement of a service larger in occupied bandwidth can be met and the data transmission efficiency is improved. A data transmitting terminal is pre-bound to a plurality of data transmission channels. The data transmitting method comprises the steps of dividing the data stream of a to-be-transmitted original internet protocol IP into a plurality of sub-data streams by the data transmitting terminal; and respectively transmitting each sub-data stream to a data receiving terminal through one pre-bound data transmission channel by the data transmitting terminal. The data receiving method comprises the steps of respectively receiving sub-data streams transmitted through different data transmission channels by the data transmitting terminal, wherein the sub-data stream transmitted through each data transmission channel is obtained through dividing the data stream of the same original internet protocol IP; and combining the received sub-data streams to obtain the data stream of the original internet protocol IP.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a data sending and receiving method, device and data transmission system. Background technique [0002] With the development of mobile communication technology, industry applications based on mobile communication networks are developing rapidly, such as video applications such as high-definition video surveillance services and instant capture and transmission services. Such applications usually require high data transmission bandwidth. [0003] With the further popularization of video services, users have higher and higher requirements for video quality, and the transmission bandwidth required by various applications is getting higher and higher, which poses new challenges to the data transmission capabilities of terminal equipment and communication networks . For example, the uplink bandwidth required by a single camera can reach 8Mbps. On the one hand, t...
