[0061] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0062] The current message sending mode is a direct sending mode, that is, a server directly sends a target message to each terminal device connected to the server. However, the service resource in some scenarios is usually limited, which leads to the inability to quickly send the target message to a large number of terminal devices.

[0063] Taking the emergency message sending scenario in the field of network set-top boxes (the network set-top box can connect the network and the television, has the attribute of the network device, and can realize the communication function by using the Internet transmission and exchange information) and broadband television network (the broadband television network is composed of a television signal service source and a communication network broadband, and the communication network broadband is a standard operator broadband or a digital cable broadband) (the emergency message sending has the characteristics of large user group, high timeliness requirement, and high reliability requirement) as an example: assuming that there are 500w network set-top boxes, the size of the emergency message is generally not more than 10kb, here 10kb is taken as an example, the service bandwidth is 500mb, the direct sending response time between the server and the network set-top box is 2s, and the time required for sending the target message of 10kb to 500w network set-top boxes by using the current message sending mode is (500w*10kb) / 500mb+2s=102s. It can be seen that, in the case of limited service resources, the current message sending mode is difficult to meet the timeliness requirement of the emergency message sending.

[0064] In view of the fact that the current message sending mode cannot quickly send the target message to a large number of terminal devices in the case of limited service resources, the present inventor has conducted research, and finally provides a message sending method with good effect, which perfectly overcomes the defects of the current message sending mode. The basic concept of the message sending method is that the server divides each online terminal device into a first-level terminal device and a second-level terminal device, and directly sends a target message to the first-level terminal device, and then the first-level terminal device forwards the target message to the second-level terminal device.

[0065] First, the hardware architecture involved in the present application will be described.

[0066] The hardware architecture related to the present application can comprise a server and a plurality of terminal devices.

[0067] Optionally, the server can be a single server, a server cluster composed of a plurality of servers, or a cloud computing server center. The server can comprise a processor, a memory, a network interface, and the like.

[0068] Optionally, the terminal device can establish a connection with the server and communicate with the server through a wired communication network (or a wireless communication network). Optionally, the terminal device can be a network set-top box. It should be noted that the terminal device can also be other devices, such as a PC, a notebook, a tablet computer, a palm computer, a mobile phone, and the like.

[0069] Those skilled in the art should understand that the terminal device and the server listed above are only examples, and other existing or future terminal devices or servers, such as those applicable to the present application, should also be included in the protection scope of the present application and are hereby incorporated by reference.

[0070] Next, the message sending method provided by the present application will be introduced through the following examples.

[0071] First embodiment

[0072] Please refer to Figure 1 , which shows a flowchart of the message sending method provided by the present application, which can comprise:

[0073] Step S101: When receiving a target message, the server divides the terminal devices in the online terminal device list into first-level terminal devices and second-level terminal devices.

[0074] Optionally, the message sending method provided by the present application can be applied to an emergency message sending scenario in the field of network set-top boxes and broadband television networks, that is, the target message can be an emergency message, and the terminal device can be a network set-top box. In the above emergency message sending scenario, when receiving an emergency message, the server divides the terminal devices in the online network set-top box list into first-level network set-top boxes and second-level network set-top boxes.

[0075] It should be noted that the above-mentioned emergency message sending scenario is only an example, and does not mean that the message sending method provided by the present application is only applicable to the emergency message sending scenario. The message sending method provided by the present application is applicable to any scenario that needs to send a message to a large number of terminal devices in a short time, that is, any scenario that needs to send a message in a high concurrency in a short time.

[0076] Optionally, the process of dividing the terminal devices in the online terminal device list into the primary terminal devices and the secondary terminal devices can comprise: selecting the terminal devices from the online terminal device list, the selected terminal devices being the primary terminal devices, and the unselected terminal devices in the online terminal device list being the secondary terminal devices.

[0077] Step S102: The server directly sends the target message and the device information corresponding to the secondary terminal device to the primary terminal device.

[0078] The device information can comprise the network information corresponding to the secondary terminal device, for example, the IP address corresponding to the secondary terminal device.

[0079] For example, the application scenario is the emergency message sending scenario in the field of network set-top boxes and broadband television networks, and step S102 is to send the emergency message and the device information corresponding to the secondary network set-top box to the primary network set-top box.

[0080] Step S103: After receiving the target message and the device information corresponding to the secondary terminal device, the primary terminal device processes the target message and forwards the target message to the secondary terminal device corresponding to the received device information.

[0081] For example, the application scenario is the emergency message sending scenario, and after receiving the emergency message and the device information corresponding to the secondary network set-top box, the primary network set-top box displays the emergency message and forwards the emergency message to the secondary network set-top box corresponding to the received device information.

[0082] Figure 2 The message sending strategy of the application is preferably shown, that is, the server selects the terminal devices from the online terminal device list, the selected terminal devices being the primary terminal devices, and the server only directly communicates with the primary terminal devices, that is, directly sends the target message and the device information corresponding to the secondary terminal device to the primary terminal device, and the primary terminal forwards the target message to the secondary terminal device.

[0083] Step S104: After receiving the target message, the secondary terminal device processes the target message.

[0084] For example, the application scenario is the emergency message sending scenario, and after receiving the emergency message, the secondary network set-top box displays the emergency message.

[0085] It should be noted that, during the valid sending period of the target message, online terminal devices can be added in the online terminal device list, if the online terminal device is added in the online terminal device list, the added online terminal device is divided into the primary terminal device and the secondary terminal device, so that the target message is directly sent to the added primary terminal device and the target message is forwarded to the added secondary terminal based on the primary terminal device.

[0086] In the message sending method provided by the embodiment of the application, when receiving the target message, the server first divides the terminal devices in the online terminal device list into the primary terminal device and the secondary terminal device, then directly sends the target message and the device information corresponding to the secondary terminal device to the primary terminal device, the primary terminal device processes the target message on one hand and forwards the target message to the secondary terminal device corresponding to the received device information on the other hand, and the secondary terminal processes the target message. The message sending method provided by the embodiment of the application can quickly send the target message to each online terminal device using less service resources, that is, the message sending method provided by the embodiment of the application can meet the timeliness requirement of message sending in the case of limited service resources.

[0087] Second embodiment

[0088] The embodiment introduces the specific implementation process of the step S101 in the above embodiment, that is, the step of dividing the terminal devices in the online terminal device list into the primary terminal device and the secondary terminal device when the server receives the target message.

[0089] Please refer to Figure 3 , which shows the flowchart of dividing the terminal devices in the online terminal device list into the primary terminal device and the secondary terminal device, which can include:

[0090] The step S301: determining the device selection ratio value based on the service bandwidth, the number of online terminal devices in the online terminal device list, the size of the target message, the direct sending response time between the server and the primary terminal device, the forwarding response time between the primary terminal device and the secondary terminal device, and the message transmission time between the primary terminal device and the secondary terminal device.

[0091] Specifically, the implementation process of the step S301 can include:

[0092] The step a1: constructing a function with the device selection ratio as the independent variable and the total delivery time of the target message as the dependent variable based on the service bandwidth, the number of online terminal devices in the online terminal device list, the size of the target message, the direct sending response time between the server and the primary terminal device, the forwarding response time between the primary terminal device and the secondary terminal device, and the message transmission time between the primary terminal device and the secondary terminal device.

[0093] If the number of online terminal devices in the online terminal device list is denoted as m, the size of the target message is denoted as n, the service bandwidth is denoted as k, the direct response time consumption between the server and the primary terminal device is denoted as t1, the forwarding response time consumption between the primary terminal device and the secondary terminal device is denoted as t2, the message transmission time consumption between the primary terminal device and the secondary terminal device is denoted as t3, the independent variable is denoted as x, and the dependent variable is denoted as y, the number of the primary terminal devices is mx, the number of the secondary terminal devices is m(1-x), the message direct sending arrival time is (m*x*n) / k+t1, the message forwarding sending arrival time is t2+((1 / x)-1)*t3, and the total arrival time of the target message is:

[0094] y=(m*x*n) / k+t1+t2+((1 / x)-1)*t3

[0095] Wherein, m, n, k, t1, t2, t3 are known.

[0096] Step a2, draw the curve of the constructed function, and determine the value of the independent variable when the value of the dependent variable is the smallest based on the drawn curve.

[0097] The function y=(m*x*n) / k+t1+t2+((1 / x)-1)*t3 can be obtained via step S2011. After obtaining the function, the curve of the function can be drawn. For example, m=500w, n=10kb, k=500mb, t1=2s, t2=2s, t3=0.2s, and y=100*x+4+((1 / x)-1)*0.2 can be obtained by substituting the above formula, and the curve drawn for y=100*x+4+((1 / x)-1)*0.2 is shown in Figure 4 .

[0098] Step a3, determine the device selection ratio value based on the value of the independent variable when the value of the dependent variable is the smallest.

[0099] In one possible implementation, the value of the independent variable when the value of the dependent variable is the smallest can be directly determined as the device selection ratio value. In another possible implementation, in order to prevent the number of secondary terminal devices from being too large, the value of the independent variable when the value of the dependent variable is the smallest can be taken upwardly.

[0100] As shown in Figure 4 , the abscissa represents the device selection ratio, and the ordinate represents the total arrival time of the target message. From Figure 4As can be seen from the figure, x when y takes the minimum value is about 0.05. In one possible implementation, 0.05 can be directly determined as the device selection ratio value. In another possible implementation, in order to prevent the number of secondary terminal devices from being too large, the value can be taken upwards on the basis of 0.05, for example, 0.1 can be taken upwards, and 0.1 is taken as the device selection ratio value.

[0101] Step S302: selecting primary terminal devices from the online terminal device list based on the device selection ratio value, and the remaining terminal devices as secondary terminal devices.

[0102] Specifically, the process of selecting primary terminal devices from the online terminal device list based on the device selection ratio value can include: determining the number p of primary terminal devices to be selected based on the total number m of online terminal devices in the online terminal device list and the device selection ratio value, and randomly selecting p online terminal devices from the online terminal device list as primary terminal devices.

[0103] The process of determining the number p of primary terminal devices to be selected based on the total number m of online terminal devices in the online terminal device list and the device selection ratio value includes: multiplying the total number m of online terminal devices in the online terminal device list by the device selection ratio value, if the multiplication result is an integer, taking the multiplication result as the number p of primary terminal devices to be selected, and if the multiplication result is not an integer, taking the integer of the multiplication result (for example, taking the integer upwards), and taking the integer result as the number p of primary terminal devices to be selected.

[0104] For example, the total number of online terminal devices in the online terminal device list is 100, the device selection ratio value is 10%, 100*10% = 10, and it is determined that the number of primary terminal devices to be selected is 10, that is, 10 terminal devices are selected from the online terminal device list as primary terminal devices. When selecting 10 terminal devices from the online terminal device list, 10 terminal devices can be randomly selected from the online terminal device list.

[0105] For example, the total number of online terminal devices in the online terminal device list is 125, the device selection ratio value is 10%, 125*10% = 12.5, and since 12.5 is not an integer, 12.5 is rounded, for example, 12.5 can be rounded upwards to obtain 13, and it is determined that the number of primary terminal devices to be selected is 13, that is, 13 terminal devices are selected from the online terminal device list as primary terminal devices.

[0106] After the primary terminal devices are selected from the online terminal list, the remaining terminal devices are secondary terminal devices.

[0107] Third embodiment

[0108] The embodiment introduces the implementation process of "step S102: the server directly sends the target message and the device information corresponding to the secondary terminal device to the primary terminal device" in the above embodiment.

[0109] Please refer to Figure 5 , which shows the flowchart of the server directly sending the target message and the device information corresponding to the secondary terminal device to the primary terminal device, which can include:

[0110] Step S501: Obtain the first device information set and the second device information set.

[0111] The first device information set includes the device information corresponding to each primary terminal device, and the second device information set includes the device information corresponding to each secondary terminal device.

[0112] It should be noted that after the terminal device connects to the network, it will report its corresponding device information to the server. The device information can include the network information (such as IP address) of the corresponding terminal device, and can also include the identity information (such as device identifier) of the corresponding terminal device, that is, the server has the device information corresponding to each online terminal in the online terminal list. After dividing the terminal devices in the online terminal list into primary terminal devices and secondary terminal devices, the first device information set can be composed of the device information corresponding to each primary terminal device, and the second device information set can be composed of the device information corresponding to each secondary terminal device.

[0113] It should be noted that generally, the network information (such as IP address) of the terminal device will not be frequently changed, but the network information of the terminal device may still change due to some reasons. When this situation occurs, the terminal device will send the new network information and its identity information to the server, and the server will update the network information of the terminal device identified by the received identity information to the received network information. For example, terminal device e changes the network information (such as IP address) because of restart. It detects that the network information has changed, and sends the new network information (such as new IP address) and its identity information to the server. The server can determine that the network information of terminal device e has changed according to the received identity information, and then update the network information of terminal device e to the received new network information.

[0114] Step S502: Traverse the device information in the first device information set:

[0115] Step S5021: For the current traversed device information, obtain the device information to be assigned to the primary terminal device corresponding to the current traversed device information from the second device information set.

[0116] Specifically, the process of obtaining device information from the second device information set to be assigned to the primary terminal device corresponding to the device information currently traversed can include: if the number of device information not yet assigned in the second device information set is greater than or equal to N, obtaining N device information not yet assigned from the second device information set; if the number of device information not yet assigned in the second device information set is less than N, obtaining all device information not yet assigned from the second device information set.

[0117] Wherein, N is determined based on the device selection value ratio. If the device selection ratio value is represented as r, N is determined based on 1-r and r. Specifically, if (1-r) / r is an integer, N=(1-r) / r, for example, if the device selection ratio value is 10%, N=(1-10%) / 10%=9; if (1-r) / r is not an integer, (1-r) / r can be rounded, and N is equal to the rounding result of (1-r) / r, for example, (1-r) / r can be rounded down, and N is equal to the rounding down result of (1-r) / r.

[0118] Step S5022: sending the target message and the device information obtained from the second device information set to the primary terminal device corresponding to the device information currently traversed.

[0119] When sending the target message and the device information obtained from the second device information set to the primary terminal device corresponding to the device information currently traversed, the target message and the device information obtained from the second device information set can be packaged into a whole and sent to the primary terminal device corresponding to the device information currently traversed. When sending the packaged data, the corresponding long connection can be found based on the identity information in the device information currently traversed, and the packaged data is sent out based on the long connection.

[0120] The process of step S402 will be described below in combination with a specific example:

[0121] Suppose there are 100 terminal devices in the online terminal device list, and the device selection ratio is 10%, then there are 10 primary terminal devices and 90 secondary terminal devices, i.e. there are 10 device information in the first device information set and 90 device information in the second device information set: for the first device information f 1-1 , 9 network information f 2-1 ~f 2-9 (including 9 IP addresses) are obtained from the second device information set, and the target message and the 9 network information f 2-1 ~f 2-9 are packaged and sent to the corresponding terminal device f 1-1 ; for the second device information f 1-2Get 9 network information f from the second device information set 2-10 ~f 2-18 (for example, 9 IP addresses), pack the target message and the 9 network information f 2-10 ~f 2-18 and send to the corresponding terminal device 1-2 for the 10th device information f in the first device information set 1-10 Get 9 network information f from the second device information set 2-82 ~f 2-90 (for example, 9 IP addresses), pack the target message and the 9 network information f 2-82 ~f 2-90 and send to the corresponding terminal device 1-10 .

[0122] It should be noted that in some cases, there may be a case where the device information in the second device information set is still not allocated after the end of the traversal of the device information in the first device information set. In this case, the following strategy can be used:

[0123] If the unallocated device information is one, the target message is directly sent to the secondary terminal device corresponding to the device information. If the unallocated device information is multiple, one device information (which can be randomly selected) is selected from the multiple unallocated device information as the target device information, and the target device information and the non-target device information in the multiple unallocated device information are sent to the secondary terminal device corresponding to the target device information, so that the secondary terminal device corresponding to the target device information sends the target message to the secondary terminal device corresponding to the non-target device information.

[0124] It should be noted that in the process of traversing the device information in the first device information set, there may be a case where there is no unallocated device information in the second device information set when traversing a certain device information. In this case, only the target message is sent to the corresponding primary terminal device from the current traversed device information.

[0125] The primary terminal device receives the target data and device information from the server, processes the target message on one hand, and on the other hand, based on the network information (such as IP address) in the received device information, forwards the target message to the secondary terminal corresponding to the device information. The secondary terminal processes the target message after receiving the target message.

[0126] Fourth embodiment

[0127] In order to ensure that the target message can reach each online terminal, the embodiment of the present application provides another message sending method, which comprises the following processes in addition to the steps S101-S104 in the above embodiment:

[0128] After receiving the target message, each terminal device (primary terminal device and secondary terminal device) sends a feedback message indicating that the target message has been reached to the server; the server marks the terminal device sending the feedback message in the online terminal list after receiving the feedback message from the terminal device every time; and the server re-sends the target message to the terminal devices not marked in the online terminal list after the ideal simple reach time of the target message.

[0129] It should be noted that the feedback message comprises a message reach mark and identity information (such as device mark) of the terminal device sending the feedback message, and the server can know which terminal device the target message reaches according to the identity information in the feedback message after receiving the feedback message, and then mark the terminal device reaching the target message in the online terminal list.

[0130] When re-sending the target message, the server preferably sends the target message directly to the terminal devices not marked in the online terminal list. Generally, the terminal devices not marked in the online terminal list are not many, and in order to ensure that the target message reaches these terminal devices, the direct sending mode is preferably adopted, that is, the target message is re-sent directly to the terminal devices not marked in the online terminal list. Of course, when re-sending the target message, the direct sending + forwarding strategy can also be adopted for re-sending, for example, a terminal device is selected from the terminal devices not marked, and the server sends the target message and the device information corresponding to other terminal devices not marked to the terminal device, so that the selected terminal device forwards the target message to other terminal devices not marked.

[0131] In the message sending method provided by the embodiment of the present application, when receiving a target message, the server first divides the terminal devices in the online terminal device list into primary terminal devices and secondary terminal devices, and then sends the target message and the device information corresponding to the secondary terminal devices to the primary terminal devices. The primary terminal devices process the target message and forward the target message to the secondary terminal devices corresponding to the received device information, so that the secondary terminal devices process the target message. In order to ensure that the target message can be sent to each terminal device, each terminal device sends a feedback message indicating that the target message has been sent to the server after receiving the target message. The server marks the terminal device sending the feedback message in the online terminal device list each time the server receives the feedback message. After the ideal simple sending time of the target message is reached, the server re-sends the target message to the terminal devices not marked in the online terminal device list. The message sending method provided by the embodiment of the present application can quickly send the target message to each online terminal device using less service resources. In addition, the sending confirmation strategy and the message re-sending strategy of the target message can ensure that the target message is sent to each terminal device.

[0132] Taking the network set-top box and the broadband television network field as an example, assuming that there are 500w network set-top boxes, the size of the emergency message is 10kb, the service bandwidth is 500mb, the direct sending response time between the server and the network set-top box is 2s, the forwarding response time between the primary terminal device and the secondary terminal device is 2s, and the message transmission time between the primary terminal device and the secondary terminal device is 0.2s. If the device selection ratio determined by the method provided by the embodiment of the present application is 0.05, the time required for sending the 10kb target message to the 500w network set-top boxes using the sending strategy provided by the present application is y=100*x+4+((1 / x)-1)*0.2=100*0.05+4+((1 / 0.05)-1)*0.2≈13s. The 13s is the simple sending time. In addition, the time required for the terminal device to send the feedback message to the server is 2s, and the time required for the message re-sending is 5s. The total time is 20s. It should be noted that the message re-sending time of 5s is calculated by taking 5% (the normal network sending rate is about 98%, and here 95% is taken as an example) of the devices that need to be re-sent: 25w*10k / 500m=5s.

[0133] The above content mentions that the time required for sending the 10kb target message to the 500w network set-top boxes using the existing message sending method is (500w*10kb) / 500mb+2s=102s, which is only the simple sending time.

[0134] Compared with the time consumption of the two sending modes, it can be seen that the time consumption of the sending method provided by the embodiment of the application is far less than that of the existing message sending mode. It can be seen that the message sending method provided by the embodiment of the application can quickly send the target message to each online terminal device by using less service resources.
