Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to an information transmission method, device and readable storage medium. Background Art

[0002] Customer Premise Equipment (CPE) refers to a device that receives information sent by a terminal through a wifi network in a network, and sends the information to a base station through an uplink control channel using a 4G or 5G network. CPE enables more terminals to access a 4G or 5G network and enjoy the performance advantages of a 4G or 5G network at the same time. The common joint networking method of 4G or 5G and WIFI is: CPE accesses 4G or 5G, and the terminal accesses CPE through WIFI. This networking method can achieve the purpose of multiple terminals enjoying the performance of a 5G network. However, what restricts the CPE and networking performance is the information transmission rate on the sending side after the CPE receives the information; that is to say, when multiple terminals simultaneously access the CPE for information transmission, the information (data) throughput on the CPE receiving side is much higher than the information (data) throughput on the CPE sending side. Generally speaking, the throughput rate of terminal information received by the CPE receiving side can reach up to 1Gbps, while the throughput rate of uplink information on the sending side (5G side) is only 200Mbps. This causes the CPE sending side to be unable to transmit information in a timely manner, resulting in information congestion.

[0003] It can be seen that in the prior art, there is a problem that the information transmission rate (throughput) on the CPE sending side is low, resulting in a decrease in the overall information transmission efficiency of the network. Summary of the invention

[0037] In view of the problem in the prior art that the information transmission rate on the CPE sending side is low, resulting in a decrease in the overall information transmission efficiency of the network, the embodiment of the present application proposes an information transmission method: first determine the first CPE with the highest spectrum efficiency in the network and the bandwidth margin of the first CPE, then determine the link whose bandwidth demand meets the bandwidth margin of the first CPE, and adjust the link for the corresponding terminal to send information to the first CPE to complete the information transmission. By using the first CPE to forward the information sent by the terminal corresponding to the link to the base station, the purpose of improving bandwidth utilization and improving the overall information transmission efficiency (throughput) of the network is achieved.

[0038] In order to better understand the above technical scheme, the technical scheme of the present application is described in detail below through the accompanying drawings and specific embodiments. It should be understood that the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

[0039] Please refer to Figure 1 The embodiment of the present application provides an information transmission method for improving the information transmission efficiency (throughput) in the network. The method specifically includes the following implementation steps:

[0040] Step 101: Determine the spectrum efficiency of all customer terminal equipment (CPE) in the network forwarding received information to the base station at set intervals.

[0041] Specifically, spectrum efficiency indicates the bandwidth resources occupied by the CPE sending side for transmitting information of unit size at the same transmission rate. The distance between CPE and base station (different surrounding interference) and the difference in its own performance lead to different efficiencies of CPE when transmitting information. Generally, CPE closer to base station has higher spectrum efficiency due to better channel environment. In networking, all CPEs, CPE and terminal, and CPE and base station can communicate or coordinate information according to the protocol defined by the networking. There can be many settings for networking. By using the interaction channels and interaction protocols between CPEs in the networking, information coordination and interaction can be carried out between CPEs without the terminal's perception. For example: Easy Mesh networking, in Easy Mesh networking, you can select any CPE as the central control CPE to receive network information of all CPEs in the networking, and coordinate and interact information based on all CPE network information. Among them, the terminals are connected to the corresponding CPEs respectively, and the corresponding CPEs are connected to the central control CPE. That is to say, all CPEs can exchange data and information with the central control CPE, and all CPEs can exchange data and information through the central control CPE; and the (wireless) terminal can access one of the CPEs according to the situation (for example, the distance between the CPE and the terminal). For example, terminal 1 and terminal 2 access CPE1 through corresponding links, terminal 3 and terminal 4 access CPE2 through corresponding links, and terminal 5 and terminal 6 access the central control CPE through corresponding links. Among them, CPE1 and CPE2 are both connected to the central control CPE, while terminal 1, terminal 2, terminal 3, and terminal 4 are not connected to the central control CPE. In this way, the network information of all CPEs in the network received by the central control CPE can be obtained at set intervals; wherein, the network information includes the spectrum efficiency when the corresponding CPE forwards the received information to the base station. Then, based on the network information, the spectrum efficiency when all the CPEs forward the received information to the base station is determined.

[0042] Step 102: Determine a first CPE whose spectrum efficiency is within a set range and a bandwidth margin of the first CPE.

[0043] Specifically, the bandwidth margin indicates the unused broadband resources for transmitting information per unit time on each link accessing the CPE. The bandwidth margin can be obtained by detection. Therefore, a threshold value can be set, and the threshold value can be subtracted from the data obtained by each detection to avoid the detection result being too small, which affects the implementation of the method provided in the embodiment of the present application. The first CPE can have the highest spectrum efficiency.

[0044] Step 103: Determine a second link for accessing any second CPE whose bandwidth requirement does not exceed the bandwidth margin, and adjust the destination of the second link to the first CPE.

[0045] Specifically, the determination of bandwidth requirements can be diverse, including but not limited to the rate and throughput of information transmission. In the embodiments of the present application, specific description is given for using the transmission rate of information to represent bandwidth requirements. The meaning of transmission rate is the amount (size) of data transmitted per second. Because the CPE needs to forward the information after receiving it, the transmission rate of the information received by the CPE on the link can be regarded as the bandwidth requirement of the link. Then, the transmission efficiency can indicate the broadband resources occupied by each CPE receiving the information sent by each terminal.

[0046] The second CPE may be any CPE in the network except the first CPE. Preferably, the CPE with the lowest spectrum efficiency in the network is determined as the second CPE. Then, the second link may be determined by first determining the second CPE with the lowest spectrum efficiency in the network. Then, among all the links accessing the second CPE, a second link having a bandwidth requirement less than the bandwidth margin of the first CPE is determined; wherein the destination of the second link is the second CPE.

[0047] A common situation is that the number of second links connected to the second CPE is greater than 1, that is, multiple terminals establish a second link with the second CPE through wifi to transmit information, wherein each terminal corresponds to an independent second link. It can be seen that when the number of second links is greater than 1, it is necessary to determine whether the sum of the bandwidth requirements (transmission rate) of all second links does not exceed the bandwidth margin of the first CPE; if not, it is necessary to delete at least one second link so that the sum of the remaining second link bandwidth requirements does not exceed the bandwidth margin of the first CPE. The present application provides an optional embodiment: delete the link with the smallest bandwidth requirement in the second link until the sum of the bandwidth requirements of all the second links is no greater than the bandwidth margin of the first CPE.

[0048] For example, Table 1 shows the spectrum efficiency, broadband efficiency and transmission rate of terminal information transmission of each CPE in a certain network. Among them, STA1~SAT10 represent the first link to the tenth link, CPE 1 accesses the links STA8, STA9, STA10; CPE 2 accesses STA1, STA3, STA2; CPE 3 accesses STA4, STA5; CPE 4 accesses STA6, STA7.

[0049] As shown in Table 1, CPE No. 2 has the highest spectrum efficiency and a bandwidth margin of 10Mbps, so CPE No. 2 is used as the first CPE. Then, in order to optimize the information transmission efficiency in the network, CPE No. 4 with the lowest spectrum efficiency (worst channel environment) is preferred as the second CPE. Then, in the link accessing the second CPE (CPE No. 4), it can be determined that the transmission rate (8Mbps) on STA6 is lower than the bandwidth margin (10Mbps) of the first CPE (CPE No. 2). Therefore, it can be determined that the destination of STA6 is adjusted to the first CPE (CPE No. 2).

[0050] Table 1

[0051]

[0052] Step 104: Based on the first link between the first CPE and the base station, forward the first information sent by the terminal corresponding to the second link to the base station.

[0053] Specifically, first, the address of the first CPE is determined. Then, based on the address of the first CPE, after receiving the terminal information sent by the second link, the second CPE can forward the first information sent by the terminal corresponding to the second link to the first CPE, so that the first CPE sends the first information to the base station through the first link.

[0054] It should be noted that the first information forwarded based on the first link between the first CPE and the base station described in this step can be sent to any central control CPE selected in the networking after the second CPE receives the first information, and the central control CPE sends the first information to the first CPE, and then the first CPE sends it to the base station through the first link using the 4G or 5G network. It is also possible that after the second CPE receives the first information, it directly sends the information to the first CPE, and then the first CPE sends it to the base station through the first link using the 4G or 5G network.

[0055] In the embodiment of the present application, the method of improving the overall information transmission efficiency of the network by adjusting the CPE that transmits uplink information is also applicable to the transmission of downlink information in the network, and can also achieve the purpose of improving the overall information transmission efficiency of the network. The specific execution steps are consistent with the above steps and will not be repeated here.

[0056] Based on the above steps 101 to 104, the following example describes information transmission for Easy Mesh networking. Please refer to Figure 2 .

[0057] Assume that there are multiple CPEs in an Easy Mesh network consisting of wifi and 5G networks, so that at least one terminal in the Easy Mesh network relies on the link between itself and the CPE, the link between CPEs, and the link between the CPE and the base station, and uses the wifi signal and the 5G network to send uplink information. Detect the uplink spectrum efficiency of each CPE (CPE 1, CPE 2, CPE 3, CPE 4) respectively, determine the bandwidth margin and the transmission efficiency of the information received on each link. Select any CPE as the central control CPE (controller, CPE 4) to receive the network information reported by the aforementioned CPEs; the network information includes the uplink spectrum efficiency, bandwidth margin, and the transmission rate of the information of the corresponding terminal transmitted on the access link. The central control CPE arranges the reported network information from high to low according to the spectrum efficiency, and selects the CPE with high spectrum efficiency and non-zero bandwidth margin as the target CPE. In order to maximize the transmission efficiency of information in the network, the transmission rate of the link connected to the CPE with the lowest 5G spectrum efficiency can be scanned first to determine the target link whose information transmission rate is not higher than the target CPE bandwidth margin; and record the target CPE, the CPE with the lowest spectrum efficiency, and the target link. Then the CPE with the lowest spectrum efficiency can be notified to cut off the original 5G transmission link and stop forwarding the received information on the target link to the base station; and forward the information to the central control CPE (Controller), which sends the information to the target CPE, and finally the target CPE sends the information to the base station to complete the information transmission. In particular, after the central control CPE receives the reported network information and determines the target CPE, when the link transmission rate of the CPE with the lowest 5G spectrum efficiency is higher than the bandwidth margin of the target chain CPE, the remaining CPEs are polled in order from low to high spectrum efficiency until the polling is completed. If it is found that there is no non-target CPE whose information transmission rate on the accessed link is not higher than the bandwidth margin of the target CPE, wait for the next adjustment cycle and readjust.

[0061] The determining unit 302 is configured to determine a first CPE whose spectrum efficiency is within a set range and a bandwidth margin of the first CPE.

[0062] Adjustment unit 303: Determine a second link accessing any second CPE whose bandwidth requirement does not exceed the bandwidth margin, and adjust a destination of the second link to the first CPE.

[0063] Specifically, a second CPE with the lowest spectrum efficiency in the network is determined; among all links accessing the second CPE, a second link having a bandwidth requirement less than a bandwidth margin of the first CPE is determined; wherein a destination of the second link is the second CPE.

[0064] The adjustment unit 303 is also used to, when the number of the second links is greater than 1, determine whether the sum of the bandwidth requirements of all the second links does not exceed the bandwidth margin of the first CPE; if not, delete the link with the smallest bandwidth requirement from the second links until the sum of the bandwidth requirements of all the second links is no greater than the bandwidth margin of the first CPE.
