Technical Field

Background
With the rapid development of mobile communication technology, the communication system can provide more diversified services for people, such as intelligent driving, remote medical treatment, intelligent home, industrial monitoring and the like. By formulating communication protocols under different communication requirements, operators can provide more reliable communication services, for example, 2G/3G/4G communication protocols mainly provide stable and high-speed communication services outdoors; a WLAN (Wireless Local Area Networks) communication protocol mainly provides a Wireless access service indoors; the NB-IoT (Narrow Band Internet of Things over cellular) protocol mainly provides low power consumption, wide coverage, low rate access service, and the like. To meet the diverse business demands, devices often support multiple sets of communication protocols. For example, a smart phone supports both the connection to the internet using an LTE (Long Term Evolution) protocol and the connection to the internet using a WLAN protocol.
Currently, because a communication control module of a device only has a control function, for an existing communication device, only one communication protocol can be selected for communication by one communication device at a time. Only when the device detects that the current link quality is poor or that there is a link with better link quality, the device will switch to the link of the other communication protocol. For example, when the handset detects that there is an accessible WLAN network nearby, the handset will disconnect the LTE network and automatically switch to the WLAN network.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, 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 invention.
In a conventional communication method, a communication control module of a device is a simple control module, and data packets from a plurality of communication modules cannot be combined. Therefore, the equipment can only use one set of communication protocol to communicate at one time, and a plurality of sets of communication protocols are independent. Even if the traffic of the device is large, the device can only use the transmission resource of one set of communication protocol and idle the transmission resources of other communication protocols, and the utilization rate of the transmission resources is low. Moreover, because a device can only communicate using one set of communication protocols at a time, the uplink and downlink of the device can only communicate using symmetric protocols. When there is a large difference between the uplink and downlink traffic or the link quality, the device cannot select different communication protocols for the uplink and the downlink, and the transmission efficiency is low.
Due to the limitation of the function of the communication control module, the traditional communication method cannot fully utilize the transmission resources of multiple sets of communication protocols, and the traditional communication method cannot enable the uplink and downlink to adopt different communication protocols according to the traffic and the link quality of the uplink and downlink, so that the transmission efficiency is low.
Embodiment 1 of the present invention discloses a multi-protocol hybrid communication method, and referring to fig. 1, fig. 1 is a flowchart of the multi-protocol hybrid communication method according to the embodiment of the present invention, including:
s101, acquiring service data, wherein the service data comprises a plurality of data packets.
The service data is data generated by an application layer of the terminal, the application layer is an interface between a computer user and various application programs and a network, and the function of the service data is to directly provide services for the user and complete various tasks that the user wants to complete on the network. The application layer is responsible for completing the contact between the application program and the network operating system in the network, establishing and ending the contact between users, and completing various network services proposed by network users, such as file service, directory service, file transmission service, remote login service, e-mail service, printing service, security service, network management service, database service, and the like, so that corresponding business data can be generated. The service data is transmitted in the form of data packets.
S102, according to the service volume of the service data and the states of the communication links corresponding to different protocols, selecting a plurality of communication links from the communication links as sending links.
The traffic of the service data generated by the application layer is constantly changing, the traffic may be very large in one period of time, and the traffic may be very small in another period of time; in addition, different communication protocols have corresponding communication links, for example, the LTE communication protocol has an LTE communication link, and the WLAN communication protocol has a WLAN communication link, and in practical situations, different communication link states are different, some communication link channel states are good, and some communication link channel states are poor. Therefore, a plurality of communication links in the communication links can be reasonably selected as the sending links according to the traffic volume and the communication link state, the communication link resources are fully utilized, and the data transmission efficiency is improved. Generally, the number of transmission links may be 2 or more.
Optionally, the traffic volume of the service data may be determined by a packet queue length of the service data. Typically, the packets are buffered in memory in the form of queues. As described above, the traffic data is transmitted in the form of packets, and thus, by determining the length of the packet queue, the traffic volume of the traffic data can be quantitatively determined.
Optionally, the process of selecting multiple communication links in the communication links as the transmission links according to the traffic of the service data and the states of the communication links corresponding to different protocols may be:
s1021, determining the communication quality of each communication link in the communication links corresponding to different protocols.
Communication Quality of communication links corresponding to different protocols can be detected by a link Quality measurement method defined by each communication protocol, for example, CQI (Channel Quality Indication) information in the LTE system; of course, the link quality measurement method may also be customized, such as periodically sending a fixed length test sequence. The above examples are merely illustrative of ways to determine the communication quality of a communication link and are not limiting of ways to determine the communication quality of a communication link.
And S1022, determining the traffic volume of the service data, and comparing the traffic volume with a preset threshold value.
And determining the traffic of the service data according to the length of the data packet queue of the service data, comparing the traffic with a preset threshold value, and further selecting one or more communication links. The preset threshold may be set according to the historical traffic volume, for example, the preset threshold may be set according to the traffic volume within 1 period, and the period may be 1 minute, 1 hour, and the like. The technical personnel can flexibly set the preset threshold value according to the actual situation.
S1023, if the traffic exceeds a preset threshold, selecting a plurality of communication links in the communication links corresponding to different protocols as sending links according to the sequence from high communication quality to low communication quality of the communication links.
After the traffic is compared with the preset threshold, if the traffic exceeds the preset threshold, the traffic is large, and data can be transmitted efficiently through a plurality of communication links. The system sorts the communication quality of the communication links corresponding to different protocols according to the sequence from high to low, and preferentially selects the communication link with the highest communication quality as a sending link;
and if the traffic volume does not exceed the preset threshold, the system selects the communication link with the best communication quality from the communication links corresponding to different protocols as a sending link.
S103, adding a packet header structure to the data packet, and generating a first data packet with the packet header structure, wherein the packet header structure comprises: packet number and packet length.
When multi-protocol hybrid communication is carried out, a packet header structure is added to a data packet of service data to identify information such as the number and the length of the data packet, so as to ensure that after a plurality of data packets of the same service data are transmitted through communication links of different protocols, an opposite end (receiving end) can recombine the service data according to the number, thereby avoiding service data confusion. Meanwhile, the length of the data packet can assist the system to identify different service data. Referring to fig. 2, fig. 2 is a schematic diagram of a packet header structure of a multi-protocol hybrid communication method according to an embodiment of the present invention, in which the packet header structure of a data packet includes a data packet number and a data packet length, where the data packet number and the data packet length each occupy 2 bytes of space. Of course, the packet header structure shown in fig. 2 is only an example of the packet header structure of the data packet in the embodiment of the present invention, and is not limited.
S104, sending the first data packet through the sending link so that the opposite end receives the first data packet.
After selecting the transmission link, the system transmits a data packet with a packet header structure, i.e. a first data packet, through the transmission link, so that the opposite end receives the first data packet. The process of transmitting data packets through the transmission link is the same as that of the existing transmission method, and therefore, the description thereof is omitted.
If the data can not be transmitted on the first sequential transmission link due to the burst condition, the system selects the second sequential communication link as the transmission link to transmit the data packet.
According to the multi-protocol hybrid communication method in embodiment 1 of the present invention, multiple communication links in the communication links are selected as the transmission links according to the traffic of the service data and the states of the communication links corresponding to different protocols, and multiple sets of communication protocols are used for communication at the same time, so that the transmission efficiency of the system is improved.

and S105, acquiring a second data packet with a packet header structure.
The second data packet with the packet header structure may be received from a first data packet with the packet header structure sent by the current end, or may be received from a data packet sent by another communication device, where the "first" of the first data packet and the "second" of the second data packet are used to distinguish the data packets, and are not limited to specific data contents.
And S106, sequencing the second data packets according to the data packet numbers in the packet header structure to generate the sequenced data packets.
The received packet header structures of the plurality of second data packets contain numbering information, and the system sorts according to the number of each data packet to generate the sorted data packets, so that readable data is formed.
And S107, transmitting the sequenced data packets to enable the application layer to process the sequenced data packets and send the processed data packets to the current end.
The system transmits the sequenced data packets to an application layer, the application layer processes the sequenced data packets and sends the processed data packets to the current end through a sending link, and therefore data interaction is formed. In the process of sending the data packet to the current end, one sending link may be selected, or a plurality of sending links may be selected. The current end refers to a terminal that transmits the first data packet through the transmission link.

In a test scenario 1, uplink and downlink of a system adopt different protocols for communication, and all data of equipment 1 can only be sent to equipment 2 through a No. 2 link by using an LTE protocol; and all data of device 2 can only be sent to device 1 over the # link using the WLAN protocol. In the test scenario 2, the device 1 can simultaneously use the LTE protocol and the WLAN protocol to send data to the device 2, that is, transmit data to the device 2 through the link No. two and the link No. six; and device 2 can only transmit data to device 1 via the WLAN protocol, i.e., via the link # c. In scenario 2, when the application program of the device 1 has service data to send, the application program transmits the service data to the virtual communication module, the virtual communication module preferentially allocates the data to the WLAN network card, and starts to allocate the data to the LTE communication module when the WLAN link is close to saturation.
And testing the communication rate between the devices in a file transmission mode. When the device 1 transmits a file to the device 2, a large amount of file data needs to be transmitted in the downlink, and only a small amount of feedback and control information is transmitted in the uplink. The test results of the system are shown in table 2, and table 2 shows the results of comparing the file transfer rates in two different scenarios, namely, test scenario 1 and test scenario 2.
TABLE 2 comparison of transfer rates of a file under different scenarios
As shown in table 2, in test scenario 1, device 1 transmits a file to device 2 by using an LTE protocol, where the rate is 0.98Mbps, which indicates feasibility of communication between uplink and downlink of the system by using different protocols; in the test scenario 2, the device 1 simultaneously adopts the WLAN protocol and the LTE protocol to transmit a file to the device 2 at a rate of 1.8 Mbps. Compared with the test scenario 1, the transmission rate in the test scenario 2 is improved by about 83.67%, and further proves that the multi-protocol communication is used in a mixed manner, so that the utilization rate of transmission resources can be improved, and the transmission efficiency of the system can be improved.
