Description

[0001] This application is a divisional application of the invention patent application filed on July 25, 2017, with application number 2017800006870 and entitled "Method, Apparatus and System for Transmitting Data". Technical Field

[0002] This application relates to the field of wireless communication technology, and in particular to a method, apparatus and system for transmitting data. Background Technology

[0003] With the development of wireless communication technology, more and more terminals can support multi-band operation, such as smartphones, tablets, and laptops. These terminals can not only use WiFi (Wireless-Fidelity) for wireless communication, but also use cellular networks, such as 4G (the 4G standard). th Generation Mobile Networks (4th generation mobile communication networks).

[0004] WiFi offers advantages such as high bandwidth, low cost, and high flexibility. Cellular network operators often deploy WiFi access points (APs) in locations such as commercial centers, airport waiting rooms, and residential areas. When both WiFi and cellular networks are available, most people prefer to use WiFi for wireless communication. Specifically, when a terminal needs to transmit target data to a server, it can do so via WiFi, i.e., by sending the target data to the AP. After receiving the target data, the AP can then forward it to the server.

[0005] In the process of realizing this disclosure, the inventors discovered at least the following problems:

[0006] When too many terminals are connected to an access point (AP), the AP becomes overloaded, often slowing down the data transmission rate of each terminal. When the AP receives target data from a terminal, a heavy AP load will result in slow data transmission rates for the terminal, leading to low data transmission efficiency. Summary of the Invention

[0160] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0161] An exemplary embodiment of this disclosure provides a method for transmitting data, which can be implemented jointly by a terminal and a WiFi access point (AP). The terminal can be a device that can use WiFi and cellular networks, such as a smartphone, smartwatch, or tablet, and the AP can be a wireless network access point deployed by major telecom operators.

[0162] The terminal may include components such as a processor, memory, and transceiver. The processor, such as a CPU (Central Processing Unit), is used for processing related to detecting changes in the availability of the cellular network. The transceiver is used to send target data, send notifications of changes in cellular network availability, send data transmission failure notifications, receive offloading messages, and receive base station handover messages. The memory, such as RAM (Random Access Memory) or Flash memory, is used to store received data, data required for processing, and data generated during processing, such as target data, cellular network availability change notifications, and data transmission failure notifications.

[0163] An access point (AP) may include components such as a processor, memory, and transceiver. The processor, such as a CPU, is used for tasks such as traffic offloading and marking the data transmission capabilities of base stations. The transceiver is used for tasks such as receiving target data, receiving notifications of changes in cellular network availability, receiving data transmission failure notifications, sending traffic offloading messages, and sending base station handover messages. The memory, such as RAM or Flash memory, is used to store received data, data required for processing, and data generated during processing, such as target data, cellular network availability change notifications, data transmission failure notifications, and the data transmission capabilities of marked base stations.

[0164] The following will describe the implementation methods. Figure 1 The processing flow shown is explained in detail below:

[0165] In step 101, when the terminal detects a change in the availability status of the cellular network, it sends a notification of the change in cellular network availability status to the Wi-Fi access point (AP).

[0166] The cellular network availability status change notification carries cellular network availability status information to indicate whether the terminal can currently use the cellular network. Changes in cellular network availability status can include the terminal reconnecting to the cellular network (specifically, reconnecting to a cellular network with the same radio access technology as before disconnection), the terminal switching to another base station while connected to the cellular network (specifically, switching to another base station with the same radio access technology as the source base station while connected to the cellular network), or the terminal disconnecting from the cellular network.

[0167] In implementation, when a terminal detects a reconnection to a cellular network, or switches to another base station while connected to a cellular network (specifically, when the terminal detects a reconnection to a cellular network using the same wireless access technology as before the disconnection, or switches to another base station while connected to a cellular network), it can send a cellular network availability status change notification to the access point (AP). In this case, the cellular network availability status change notification can carry cellular network availability status information indicating that the terminal can currently use the cellular network, thus informing the AP that the terminal can currently use the cellular network. Conversely, when a terminal detects a disconnection from the cellular network, it can send a cellular network availability status change notification to the AP. In this case, the cellular network availability status change notification can carry cellular network availability status information indicating that the terminal is currently not using the cellular network, thus informing the AP that the terminal is currently not using the cellular network.

[0168] Optionally, the cellular network availability status change notification sent by the terminal may also include the base station identifier of the first base station to which the terminal is currently connected.

[0169] In implementation, such as Figure 2 As shown, when the terminal detects that it has reconnected to a cellular network with the same wireless access technology as before the disconnection, the cellular network availability status change notification sent to the AP can also carry the base station identifier of the first base station currently connected, in order to inform the AP terminal that it is currently connected to the aforementioned first base station.

[0170] Or, such as Figure 3 As shown, when a terminal detects that it has switched to another base station using the same wireless access technology as the source base station while connected to a cellular network, the cellular network availability status change notification sent to the AP can also carry the base station identifier of the currently connected first base station, to inform the Wi-Fi access point AP that the terminal has currently switched to the aforementioned first base station. For example, when the terminal switches from connected base station 1 to base station 2, it can send a cellular network availability status change notification carrying the base station identifier of base station 2 to the AP, to inform the AP that the terminal can currently use the cellular network and is connected to base station 2.

[0171] In step 102, the AP receives a notification of changes in cellular network availability sent by the terminal.

[0172] Corresponding to the cellular network availability status change notification sent by the terminal, the cellular network availability status change notification carries the cellular network availability status information, indicating whether the terminal can currently use the cellular network. Changes in the cellular network availability status may include the terminal reconnecting to a cellular network using the same radio access technology as before the disconnection, or the terminal switching to another base station using the same radio access technology as the source base station while connected to the cellular network, or the terminal disconnecting from the cellular network.

[0173] In practice, after the terminal sends a notification of changes in cellular network availability to the AP, the AP can then receive the notification of changes in cellular network availability sent by the terminal.

[0174] Optionally, if the cellular network availability status change notification sent by the terminal can also carry the base station identifier of the first base station currently connected, then the cellular network availability status change notification received by the AP can also carry the base station identifier of the first base station currently connected to the terminal.

[0175] In step 103, the terminal sends the target data to the AP.

[0176] The target data is the data that needs to be transmitted through the AP.

[0177] In practice, when a terminal needs to send target data to the server, it can transmit the target data to the server via WiFi, that is, it can send target data to the AP.

[0178] In step 104, when the AP receives the target data sent by the terminal, if the current load is greater than a preset quantity threshold and the cellular network availability status information is currently available, then the AP sends a diversion message to the terminal.

[0179] The diversion message is used to instruct the terminal to transmit target data based on the cellular network.

[0180] In implementation, after the terminal sends the target data to the AP, the AP can receive the target data sent by the terminal and then compare the current load with a preset quantity threshold. If the AP's current load is greater than the preset quantity threshold, the AP can determine whether the cellular network availability status information carried in the received cellular network availability status change notification sent by the terminal is currently available. If the cellular network availability status information is currently available, the AP can send a diversion message to the terminal, instructing the terminal to transmit the target data based on the cellular network.

[0181] Optionally, for cases where the cellular network availability status change notification also carries the base station identifier of the first base station currently connected to the terminal, the corresponding processing procedure of step 104 can be as follows: When the AP receives the target data sent by the terminal, if the current load is greater than the preset quantity threshold, the cellular network availability status information is currently available, and the data transmission capability of the first base station meets the preset transmission conditions, then the AP sends a diversion message to the terminal.

[0182] The data transmission capabilities of the first base station may include frame loss rate, data latency, and quality of service capacity.

[0183] In implementation, if the current load exceeds a preset threshold and the cellular network availability status is currently available, it can further determine whether the data transmission capability of the first base station currently connected to the terminal meets preset transmission conditions. If the current load exceeds the preset threshold, the cellular network availability status is currently available, and the data transmission capability of the first base station meets the preset transmission conditions, the AP can send a diversion message to the terminal, instructing the terminal to transmit target data based on the cellular network. Specifically, the AP can determine whether the data transmission capability of the first base station meets the preset transmission conditions based on the base station identifier of the currently connected first base station sent by the terminal. Specifically, the AP can search for the base station identifier of the first base station in a pre-stored list of base station identifiers whose data transmission capabilities meet the preset transmission conditions. If found, it can send a diversion message to the terminal. The specific method for storing the base station identifier list will be described in detail later.

[0184] In step 105, when the terminal receives the diversion message sent by the AP, it transmits the target data based on the cellular network.

[0185] In practice, after the AP sends a diversion message, the terminal can receive the diversion message sent by the AP, and then transmit the target data to the base station through the cellular network, so that the base station can transmit the target data to the server.

[0186] Furthermore, after the terminal transmits target data via the cellular network, if the transmission of the target data via the cellular network fails, it can also send a data transmission failure notification to the AP so that the AP can process the target data. The following will describe the implementation method in conjunction with the following description. Figure 4 The processing flow shown is explained in detail below:

[0187] In step 401, when the target data fails to be transmitted via the cellular network, the terminal sends a data transmission failure notification to the AP.

[0188] In step 402, when the AP receives a data transmission failure notification sent by the terminal, it controls the transmission of the target data.

[0189] Optionally, depending on the different ways AP processes the target data, the processing procedure in step 202 can vary. Several feasible processing methods are given below:

[0190] Method 1: The AP sends the target data.

[0191] Accordingly, for Method 1, the specific processing procedure of step 402 can be as follows: When the AP receives a data transmission failure notification sent by the terminal, it sends the target data.

[0192] In practice, after receiving a data transmission failure notification from the terminal, the AP will no longer send a diversion message to the terminal, but will continue to transmit the target data via WiFi.

[0193] Method 2: Among the base stations that the terminal can connect to, the AP determines the second base station whose data transmission capability meets the preset transmission conditions; and sends a base station handover message to the terminal, wherein the base station handover message carries the base station identifier of the second base station.

[0194] In implementation, after the terminal sends a data transmission failure notification, the AP can randomly select a second base station that the terminal can connect to from a pre-stored list of base station identifiers whose data transmission capabilities meet preset transmission conditions. Since the AP and the base station can be connected to the same core network, the AP can obtain the base station identifier of the base station that the terminal can connect to from the core network.

[0195] After the access point (AP) identifies a second base station whose data transmission capabilities meet preset transmission conditions, it sends a base station handover message to the terminal. This message carries the base station identifier of the second base station, instructing the terminal to switch its connection to that base station. For example, if the terminal fails to transmit target data via base station 1 through the cellular network, it sends a data transmission failure notification to the AP, informing the AP that the terminal is currently connected to base station 1. Upon receiving the data transmission failure notification, the AP randomly selects base station 2 from the base stations the terminal can connect to, whose data transmission capabilities meet the preset transmission conditions, and sends a base station handover message to the terminal, instructing it to switch its connection to base station 2 and transmit the target data via the cellular network.

[0196] Optionally, when the AP sends a base station handover message to the terminal, the terminal can also perform the following processing: The terminal receives the base station handover message sent by the AP, and then switches to connect to the second base station to transmit target data based on the cellular network. The base station handover message carries the base station identifier of the second base station. The base station handover message is used to instruct the terminal to switch to connect to the second base station.

[0197] In practice, after receiving a base station handover message, the terminal can disconnect from the first base station, switch to the second base station, and transmit the target data to the second base station via the cellular network, so that the second base station can transmit the target data to the server.

[0198] Optionally, for method two, the data transmission failure notification may also include the reason for the transmission failure.

[0199] The reasons for transmission failure may include: the first base station rejects terminal access, the frame loss rate of the first base station is greater than a preset threshold, the data delay of the first base station is greater than a preset threshold, the service quality capacity of the first base station is less than a preset threshold, the terminal receives a weak signal from the first base station, the interference when the terminal receives the signal from the first base station is greater than a preset threshold, and the service requested by the terminal is unavailable.

[0200] Correspondingly, for cases where the data transmission failure notification can also include the reason for the failure, the AP can also perform actions such as... Figure 5 The processing procedure is detailed below:

[0201] In step 501, if the transmission failure is caused by the data transmission capability of the first base station currently connected to the terminal, the AP marks that the data transmission capability of the first base station does not meet the preset transmission conditions.

[0202] Among them, the transmission failure caused by the data transmission capability of the first base station currently connected to the terminal may include: the frame loss rate of the first base station is greater than a preset threshold, the data delay of the first base station is greater than a preset threshold, and the service quality capacity of the first base station is less than a preset threshold, etc.

[0203] In implementation, after receiving a data transmission failure notification from a terminal, if the reason for the failure is due to the data transmission capability of the first base station currently connected to the terminal, such as the frame loss rate of the first base station exceeding a preset threshold, the data latency of the first base station exceeding a preset threshold, or the service quality capacity of the first base station being less than a preset threshold, then the AP can mark the data transmission capability of the first base station as not meeting preset transmission conditions. The base station identifier of the first base station currently connected to the terminal can be carried in the data transmission failure notification or in the cellular network availability status change notification. Specifically, if the base station identifier of the first base station currently exists in the list of base station identifiers whose data transmission capability meets the preset transmission conditions, the AP can delete the base station identifier of the first base station.

[0204] In step 502, the AP detects the data transmission capability of the first base station.

[0205] In practice, after the AP marks the data transmission capability of the first base station as not meeting the preset transmission conditions, the AP can detect the data transmission capability corresponding to the first base station from the core network, such as frame loss rate, data latency, and quality of service capacity.

[0206] In step 503, when the AP detects that the data transmission capability of the first base station meets the preset transmission conditions, it marks that the data transmission capability of the first base station meets the preset transmission conditions.

[0207] In implementation, after the AP detects the data transmission capability of the first base station, it can compare it with preset transmission conditions. When the AP detects that the data transmission capability of the first base station meets the preset transmission conditions, it can mark the first base station's data transmission capability as meeting the preset transmission conditions, that is, it can add the base station identifier of the first base station to the list of base station identifiers whose data transmission capability meets the preset transmission conditions for subsequent use. The situations in which the AP detects that the data transmission capability of the first base station meets the preset transmission conditions include: the AP detects that the frame loss rate of the first base station is less than a preset threshold, the AP detects that the data latency of the first base station is less than a preset threshold, and the AP detects that the service quality capacity of the first base station is greater than a preset threshold, etc.

[0208] In this embodiment, when the AP's load exceeds a preset threshold, the AP can send a traffic offloading message to the terminal. After receiving the offloading message, the terminal transmits the target data via the cellular network. The terminal does not need to transmit the target data through the AP with a high load, thus improving data transmission efficiency. Furthermore, before sending the offloading message, the AP can know that the terminal can currently use the cellular network. Therefore, the AP sends the offloading message to the terminal when the terminal can currently use the cellular network, thereby improving the success rate of data transmission via the cellular network.

[0209] An exemplary embodiment of this disclosure also provides a method for transmitting data, which can be implemented jointly by a terminal and a WiFi access point (AP). The terminal can be a device that can use WiFi and cellular networks, such as a smartphone, smartwatch, or tablet. The AP can be a wireless network access point deployed by major operators, such as a router.

[0210] The terminal may include components such as a processor, memory, and transceiver. The processor, such as a CPU, can be used for processing related to failures in target data transmission over the cellular network. The transceiver can be used to send target data, send notifications of changes in cellular network availability, send data transmission failure notifications, receive diversion messages, and receive base station handover messages. The memory, such as RAM or Flash memory, can be used to store received data, data required for processing, and data generated during processing, such as target data, cellular network availability change notifications, and data transmission failure notifications.

[0211] An access point (AP) may include components such as a processor, memory, and transceiver. The processor, such as a CPU, is used for offloading-related processing, marking the data transmission capabilities of base stations, and controlling the transmission of target data. The transceiver is used for receiving target data, receiving cellular network availability status change notifications, receiving data transmission failure notifications, sending offloading messages, and sending base station handover messages. The memory, such as RAM or Flash memory, is used to store received data, data required for processing, and data generated during processing, such as target data, cellular network availability status change notifications, data transmission failure notifications, and the data transmission capabilities of marked base stations.

[0212] The following will describe the implementation methods. Figure 6 The processing flow shown is explained in detail below:

[0213] In step 601, the terminal sends target data to the Wi-Fi access point (AP).

[0214] The target data is the data that needs to be transmitted through the AP.

[0215] In practice, when a terminal needs to send target data to the server, it can transmit the target data to the server via WiFi, that is, it can send target data to the AP.

[0216] Optionally, when the availability status of the cellular network changes, the terminal can also send a notification of the change in cellular network availability status to the AP. Correspondingly, the terminal can also perform the following processing: When the terminal detects a change in the availability status of the cellular network, it can send a notification of the change in cellular network availability status to the AP.

[0217] The cellular network availability status change notification carries cellular network availability status information to indicate whether the terminal can currently use the cellular network. Changes in cellular network availability status can include the terminal reconnecting to the cellular network (specifically, reconnecting to a cellular network with the same radio access technology as before disconnection), the terminal switching to another base station while connected to the cellular network (specifically, switching to another base station with the same radio access technology as the source base station while connected to the cellular network), or the terminal disconnecting from the cellular network.

[0218] In implementation, when a terminal detects a reconnection to a cellular network, or switches to another base station while connected to a cellular network (specifically, when the terminal detects a reconnection to a cellular network using the same wireless access technology as before the disconnection, or switches to another base station while connected to a cellular network), it can send a cellular network availability status change notification to the access point (AP). In this case, the cellular network availability status change notification can carry cellular network availability status information indicating that the terminal can currently use the cellular network, thus informing the AP that the terminal can currently use the cellular network. Conversely, when a terminal detects a disconnection from the cellular network, it can send a cellular network availability status change notification to the AP. In this case, the cellular network availability status change notification can carry cellular network availability status information indicating that the terminal is currently not using the cellular network, thus informing the AP that the terminal is currently not using the cellular network.

[0219] In step 602, the AP receives the target data sent by the terminal.

[0220] In practice, after the terminal sends the target data to the AP, the AP can receive the target data sent by the terminal and then transmit the target data to the server.

[0221] In step 603, if the current load is greater than a preset threshold, a diversion message is sent to the terminal.

[0222] The diversion message is used to instruct the terminal to transmit target data based on the cellular network.

[0223] In implementation, after receiving the target data sent by the terminal, the AP can compare its current load with a preset threshold. If the AP's current load exceeds the preset threshold, it can send a diversion message to the terminal, instructing the terminal to transmit the target data over the cellular network.

[0224] Optionally, when a terminal detects a change in the availability of the cellular network and can send a notification of this change to the AP, the AP can also perform the following processing: receive the notification of the change in cellular network availability sent by the terminal, wherein the notification carries cellular network availability information. Accordingly, the specific processing of step 603 can be as follows: if the current load is greater than a preset threshold and the cellular network availability information indicates that the network is currently available, then a traffic diversion message is sent to the first terminal.

[0225] The diversion message is used to instruct the terminal to transmit target data based on the cellular network.

[0226] In implementation, after the terminal sends the target data to the AP, the AP can receive the target data sent by the terminal and then compare the current load with a preset quantity threshold. If the AP's current load is greater than the preset quantity threshold, the AP can determine whether the cellular network availability status information carried in the received cellular network availability status change notification sent by the terminal is currently available. If the cellular network availability status information is currently available, the AP can send a diversion message to the terminal, instructing the terminal to transmit the target data based on the cellular network.

[0227] Optionally, the cellular network availability status change notification also carries the base station identifier of the first base station currently connected to the terminal. Accordingly, for the case where the cellular network availability status change notification also carries the base station identifier of the first base station currently connected to the terminal, the specific processing procedure of step 603 can be as follows: if the current load is greater than a preset quantity threshold, the cellular network availability status information is currently available, and the data transmission capability of the first base station meets the preset transmission conditions, then a diversion message is sent to the terminal.

[0228] The data transmission capabilities of the first base station may include frame loss rate, data latency, and quality of service capacity.

[0229] In implementation, if the current load exceeds a preset threshold and the cellular network availability status is currently available, it can further determine whether the data transmission capability of the first base station currently connected to the terminal meets preset transmission conditions. If the current load exceeds the preset threshold, the cellular network availability status is currently available, and the data transmission capability of the first base station meets the preset transmission conditions, the AP can send a diversion message to the terminal, instructing the terminal to transmit target data based on the cellular network. Specifically, the AP can determine whether the data transmission capability of the first base station meets the preset transmission conditions based on the base station identifier of the currently connected first base station sent by the terminal. Specifically, the AP can search for the base station identifier of the first base station in a pre-stored list of base station identifiers whose data transmission capabilities meet the preset transmission conditions. If found, it can send a diversion message to the terminal. The specific method for storing the base station identifier list will be described in detail later.

[0230] In step 604, when the terminal receives the diversion message sent by the AP, it transmits the target data based on the cellular network.

[0231] In practice, after the AP sends a diversion message, the terminal can receive the diversion message sent by the AP, and then transmit the target data to the base station through the cellular network, so that the base station can transmit the target data to the server.

[0232] In step 605, when the target data fails to be transmitted via the cellular network, the terminal sends a data transmission failure notification to the AP.

[0233] The failure of target data transmission over a cellular network can be caused by the terminal itself or by the data transmission capability of the first base station to which the terminal is currently connected.

[0234] In practice, after the terminal transmits the target data via the cellular network, if the transmission of the target data via the cellular network fails, the terminal can send a data transmission failure notification to the AP so that the AP can process the target data.

[0235] In step 606, when the AP receives a data transmission failure notification from the terminal, it controls the transmission of the target data.

[0236] Optionally, depending on the different ways AP processes the target data, the processing procedure in step 606 can vary. Several feasible processing methods are given below:

[0237] Method 1: The AP sends the target data.

[0238] Accordingly, for method one, the specific processing procedure of step 606 can be as follows: When the AP receives a data transmission failure notification sent by the terminal, it sends the target data.

[0239] In practice, after receiving a data transmission failure notification from the terminal, the AP will no longer send a diversion message to the terminal, but will continue to transmit the target data via WiFi.

[0240] Method 2: Among the base stations that the terminal can connect to, the AP determines the second base station whose data transmission capability meets the preset transmission conditions; and sends a base station handover message to the terminal, wherein the base station handover message carries the base station identifier of the second base station.

[0241] In implementation, after the terminal sends a data transmission failure notification, the AP can randomly select a second base station that the terminal can connect to from a pre-stored list of base station identifiers whose data transmission capabilities meet preset transmission conditions. Since the AP and the base station can be connected to the same core network, the AP can obtain the base station identifier of the base station that the terminal can connect to from the core network.

[0242] After the access point (AP) identifies a second base station whose data transmission capabilities meet preset transmission conditions, it sends a base station handover message to the terminal. This message carries the base station identifier of the second base station, instructing the terminal to switch its connection to that base station. For example, if the terminal fails to transmit target data via base station 1 through the cellular network, it sends a data transmission failure notification to the AP, informing the AP that the terminal is currently connected to base station 1. Upon receiving the data transmission failure notification, the AP randomly selects base station 2 from the base stations the terminal can connect to, whose data transmission capabilities meet the preset transmission conditions, and sends a base station handover message to the terminal, instructing it to switch its connection to base station 2 and transmit the target data via the cellular network.

[0243] Optionally, when the AP sends a base station handover message to the terminal, the terminal can also perform the following processing: The terminal receives the base station handover message sent by the AP, and then switches to connect to the second base station to transmit target data based on the cellular network. The base station handover message carries the base station identifier of the second base station. The base station handover message is used to instruct the terminal to switch to connect to the second base station.

[0244] In practice, after receiving a base station handover message, the terminal can disconnect from the first base station, switch to the second base station, and transmit the target data to the second base station via the cellular network, so that the second base station can transmit the target data to the server.

[0245] Optionally, for method two, the data transmission failure notification may also include the reason for the transmission failure.

[0246] The reasons for transmission failure may include: the first base station rejects terminal access, the frame loss rate of the first base station is greater than a preset threshold, the data delay of the first base station is greater than a preset threshold, the service quality capacity of the first base station is less than a preset threshold, the terminal receives a weak signal from the first base station, the interference when the terminal receives the signal from the first base station is greater than a preset threshold, and the service requested by the terminal is unavailable.

[0247] Correspondingly, for cases where the data transmission failure notification can also include the reason for the failure, the AP can also perform actions such as... Figure 7 The processing procedure is detailed below:

[0248] In step 701, if the transmission failure is caused by the data transmission capability of the first base station currently connected to the terminal, the AP marks that the data transmission capability of the first base station does not meet the preset transmission conditions.

[0249] Among them, the transmission failure caused by the data transmission capability of the first base station currently connected to the terminal may include: the frame loss rate of the first base station is greater than a preset threshold, the data delay of the first base station is greater than a preset threshold, and the service quality capacity of the first base station is less than a preset threshold, etc.

[0250] In implementation, after receiving a data transmission failure notification from a terminal, if the reason for the failure is due to the data transmission capability of the first base station currently connected to the terminal, such as the frame loss rate of the first base station exceeding a preset threshold, the data latency of the first base station exceeding a preset threshold, or the service quality capacity of the first base station being less than a preset threshold, then the AP can mark the data transmission capability of the first base station as not meeting preset transmission conditions. The base station identifier of the first base station currently connected to the terminal can be carried in the data transmission failure notification or in the cellular network availability status change notification. Specifically, if the base station identifier of the first base station currently exists in the list of base station identifiers whose data transmission capability meets the preset transmission conditions, the AP can delete the base station identifier of the first base station.

[0251] In step 702, the AP detects the data transmission capability of the first base station.

[0252] In practice, after the AP marks the data transmission capability of the first base station as not meeting the preset transmission conditions, the AP can detect the data transmission capability corresponding to the first base station from the core network, such as frame loss rate, data latency, and quality of service capacity.

[0253] In step 703, when the AP detects that the data transmission capability of the first base station meets the preset transmission conditions, it marks that the data transmission capability of the first base station meets the preset transmission conditions.

[0254] In implementation, after the AP detects the data transmission capability of the first base station, it can compare it with preset transmission conditions. When the AP detects that the data transmission capability of the first base station meets the preset transmission conditions, it can mark the first base station's data transmission capability as meeting the preset transmission conditions, that is, it can add the base station identifier of the first base station to the list of base station identifiers whose data transmission capability meets the preset transmission conditions for subsequent use. The situations in which the AP detects that the data transmission capability of the first base station meets the preset transmission conditions include: the AP detects that the frame loss rate of the first base station is less than a preset threshold, the AP detects that the data latency of the first base station is less than a preset threshold, and the AP detects that the service quality capacity of the first base station is greater than a preset threshold, etc.

[0255] In this embodiment, after the AP receives the target data sent by the terminal, if the AP's load exceeds a preset threshold, the AP can send a diversion message to the terminal. Upon receiving the diversion message, the terminal transmits the target data via the cellular network. This eliminates the need for the terminal to transmit the target data through an AP with a high load, thus improving data transmission efficiency. Furthermore, if the target data transmission via the cellular network fails, the terminal can notify the AP of the failure. In this case, the AP can regain control of the target data transmission, thereby improving the accuracy and success rate of data transmission via the cellular network.

[0256] Based on the same technical concept, embodiments of the present invention also provide a data transmission device, such as... Figure 8 As shown, the device includes:

[0266] Alternatively, among the base stations that the terminal can connect to, a second base station whose data transmission capability meets preset transmission conditions is identified; a base station handover message is sent to the terminal, wherein the base station handover message carries the base station identifier of the second base station.

[0267] Optionally, the data transmission failure notification may also include the reason for the transmission failure.

[0268] like Figure 10 As shown, the device further includes:

[0269] The first marking module 840 is used to mark the data transmission capability of the first base station as not meeting the preset transmission conditions if the transmission failure is caused by the data transmission capability of the first base station currently connected to the terminal.

[0270] The detection module 850 is used to detect the data transmission capability of the first base station;

[0271] The second marking module 860 is used to mark the data transmission capability of the first base station as meeting the preset transmission conditions when it is detected that the data transmission capability of the first base station meets the preset transmission conditions.

[0272] Based on the same technical concept, embodiments of the present invention also provide a data transmission device, such as... Figure 11 As shown, the device includes:

[0273] The first sending module 1110 is used to send a notification of the change in the availability status of the cellular network to the access point (AP) of Wi-Fi when a change in the availability status of the cellular network is detected.

[0274] The second sending module 1120 is used to send target data to the AP.

[0276] Optionally, the first transmitting module 1110 is used for:

[0277] When a reconnection to a cellular network using the same wireless access technology as before the disconnection is detected, or when switching to another base station using the same wireless access technology as the source base station while connected to a cellular network, a notification of the change in cellular network availability is sent to the Wi-Fi access point (AP).

[0278] Optionally, the cellular network availability status change notification may also carry the base station identifier of the first base station currently connected to the terminal.

[0284] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0285] In this embodiment, when the AP's load exceeds a preset threshold, the AP can send a traffic offloading message to the terminal. After receiving the offloading message, the terminal transmits the target data via the cellular network. The terminal does not need to transmit the target data through the AP with a high load, thus improving data transmission efficiency. Furthermore, before sending the offloading message, the AP can know that the terminal can currently use the cellular network. Therefore, the AP sends the offloading message to the terminal when the terminal can currently use the cellular network, thereby improving the success rate of data transmission via the cellular network.

[0286] Based on the same technical concept, embodiments of the present invention also provide a data transmission system, the system comprising an access point (AP) and a terminal, wherein:

[0287] The AP is used to receive a notification of a change in cellular network availability status sent by the terminal. The notification carries information about the cellular network availability status. When the AP receives target data sent by the terminal, if the current load is greater than a preset threshold and the cellular network availability status information indicates that the data is currently available, the AP sends a diversion message to the terminal. The diversion message instructs the terminal to transmit the target data based on the cellular network.

[0288] The terminal is configured to send a cellular network availability status change notification to the AP when it detects a change in the availability status of the cellular network, wherein the cellular network availability status change notification carries the cellular network availability status information, send target data to the AP, and transmit the target data based on the cellular network when it receives a diversion message sent by the AP.

[0289] In this embodiment, when the AP's load exceeds a preset threshold, the AP can send a traffic offloading message to the terminal. After receiving the offloading message, the terminal transmits the target data via the cellular network. The terminal does not need to transmit the target data through the AP with a high load, thus improving data transmission efficiency. Furthermore, before sending the offloading message, the AP can know that the terminal can currently use the cellular network. Therefore, the AP sends the offloading message to the terminal when the terminal can currently use the cellular network, thereby improving the success rate of data transmission via the cellular network.

[0290] Based on the same technical concept, embodiments of the present invention also provide a data transmission device, wherein the device may be a Wi-Fi access point (AP), such as... Figure 14 As shown, the device includes:

[0321] Regarding the apparatus in the above embodiments, the specific manner in which each module performs its operation has been described in detail in the embodiments related to the method, and will not be elaborated upon here.

[0322] In this embodiment, after the AP receives the target data sent by the terminal, if the AP's load exceeds a preset threshold, the AP can send a diversion message to the terminal. Upon receiving the diversion message, the terminal transmits the target data via the cellular network. This eliminates the need for the terminal to transmit the target data through an AP with a high load, thus improving data transmission efficiency. Furthermore, if the target data transmission via the cellular network fails, the terminal can notify the AP of the failure. In this case, the AP can regain control of the target data transmission, thereby improving the accuracy and success rate of data transmission via the cellular network.

[0323] Based on the same technical concept, embodiments of the present invention also provide a data transmission system, the system comprising an access point (AP) and a terminal, wherein:

[0324] The AP is used to receive target data sent by the terminal. If the current load is greater than a preset threshold, it sends a diversion message to the terminal. The diversion message is used to instruct the terminal to transmit the target data based on the cellular network. When it receives a data transmission failure notification sent by the terminal, it controls the transmission of the target data.

[0325] The terminal is used to send target data to the AP, and when it receives a diversion message sent by the AP, it transmits the target data based on the cellular network. When the target data fails to be transmitted based on the cellular network, it sends a data transmission failure notification to the AP.
