Description

Method, device and system for transmitting data

Technical Field

The present application relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a system for transmitting data.

Background

With the development of wireless communication technology, more and more terminals can support multi-band operation, such as smart phones, tablet computers, notebook computers and the like. These terminals may communicate wirelessly not only using WiFi (Wireless-Fidelity), but also using cellular networks, such as 4G (the 4)^thGeneration Mobile Networks, fourth Generation Mobile communications).

WiFi has the advantages of high bandwidth, low cost, strong flexibility, etc., and operators of cellular networks often arrange WiFi APs (Access points) in places such as business centers, airport lounges, cells, etc. Most people prefer WiFi for wireless communication where it is available simultaneously with the cellular network. Specifically, when the terminal is to transmit the target data to the server, the terminal may transmit the target data to the server through WiFi, that is, may transmit the target data to the AP, and after receiving the target data, the AP may transmit the target data to the server.

In carrying out the present disclosure, the inventors found that at least the following problems exist:

the number of terminals accessing the AP is too large, and the load of the AP is too large, which often slows down the data transmission rate of each terminal. When the AP receives target data sent by the terminal, if the load of the AP is large, the data transmission rate of the terminal is slow, and thus, the data transmission efficiency is low.

The transceiver may be configured to send targeted data, send a cellular network state change notification, send a data transmission failure notification, receive a offload message, receive a base station handover message.

The AP may include components such as a processor, memory, and transceiver. The processor may be a CPU, and may be configured to perform processing related to offloading, and mark data transmission capability of the base station. The transceiver may be configured to receive target data, receive a cellular network state change notification, receive a data transmission failure notification, send a offload message, send a base station switch message, and so on. The memory may be a RAM, a Flash, or the like, and may be configured to store received data, data required by the processing procedure, data generated during the processing procedure, or the like, such as target data, cellular network status change notification, data transmission failure notification, data transmission capability of the marked base station, or the like.

The process flow shown in fig. 1 will be described in detail below with reference to the embodiments, and the contents may be as follows:

in step 101, when detecting that the availability status of the cellular network changes, the terminal sends a notification of the change of the availability status of the cellular network to the access point AP of WiFi.

The cellular network availability status change notification carries cellular network availability status information, which is used for indicating whether the terminal can use the cellular network currently. The situation that the available state of the cellular network changes may include that the terminal reconnects to the cellular network (specifically, the terminal reconnects to the cellular network of the same radio access technology as that before the disconnection), or that the terminal switches to another base station if the cellular network is connected (specifically, the terminal switches to another base station of the same radio access technology as that of the source base station if the cellular network is connected), or that the terminal disconnects from the cellular network.

In an implementation, when the terminal detects that the cellular network is reconnected, or when the terminal switches to another base station in the case of connecting the cellular network (specifically, when the terminal detects that the cellular network is reconnected, which is the same as the cellular network in the radio access technology before disconnection, or switches to another base station in the case of connecting the cellular network), the terminal may send a cellular network availability status change notification to the AP, where in this case, the cellular network availability status change notification may carry cellular network availability status information indicating that the terminal may currently use the cellular network, so as to inform the AP that the terminal may currently use the cellular network. When detecting that the terminal is disconnected from the cellular network, the terminal may send a cellular network availability status change notification to the AP, and in this case, the cellular network availability status change notification may carry cellular network availability status information for indicating that the terminal does not use the cellular network currently, so as to notify the AP that the terminal does not use the cellular network currently.

Optionally, the cellular network available state change notification sent by the terminal may also carry a base station identifier of the currently connected first base station.

In implementation, as shown in fig. 2, when the terminal detects that the cellular network is reconnected, where the cellular network has the same radio access technology as that before disconnection, the cellular network available state change notification sent to the AP may also carry a base station identifier of the currently connected first base station, so as to notify the AP that the terminal is currently connected to the first base station.

Or, as shown in fig. 3, when detecting that the access point is switched to another base station having the same wireless access technology as the source base station when connecting to the cellular network, the terminal may further carry a base station identifier of the currently connected first base station to notify the access point of WiFi that the AP terminal is currently switched to the first base station. For example, when the terminal switches from the connected base station 1 to the base station 2, the terminal may send a cellular network available state change notification carrying the base station identifier of the base station 2 to the AP, so as to inform the AP that the terminal can currently use the cellular network and is connected to the base station 2.

In step 102, the AP receives a cellular network available state change notification sent by the terminal.

The cellular network state change notification carries the cellular network available state information, and is used for indicating whether the terminal can use the cellular network currently or not. The situation that the available state of the cellular network changes may include the terminal reconnecting to the cellular network of the same radio access technology as before the disconnection, or the terminal switching to another base station of the same radio access technology as the source base station in case of connecting to the cellular network, or the terminal disconnecting from the cellular network.

In implementation, after the terminal sends the cellular network availability status change notification to the AP, the AP may correspondingly receive the cellular network availability status change notification sent by the terminal.

Optionally, for a situation that the cellular network available state change notification sent by the terminal may also carry the base station identifier of the currently connected first base station, correspondingly, the cellular network available state change notification received by the AP may also carry the base station identifier of the currently connected first base station.

In step 103, the terminal transmits target data to the AP.

The target data is data to be transmitted through the AP.

In implementation, when the terminal needs to send the target data to the server, the target data may be transmitted to the server through WiFi, that is, the target data may be sent to the AP.

In step 104, when receiving the target data sent by the terminal, the AP sends a offloading message to the terminal if the current load is greater than the preset number threshold and the cellular network availability status information is currently available.

The offloading message is used to instruct the terminal to transmit the target data based on the cellular network.

In implementation, after the terminal sends the target data to the AP, the AP may receive the target data sent by the terminal, and further, may compare the current load amount with the preset number threshold. If the current load capacity of the AP is greater than the preset number threshold, the AP may determine whether the cellular network available state information carried in the cellular network available state change notification sent by the terminal is currently available, and if the cellular network available state information is currently available, may send a offload message to the terminal, for instructing the terminal to transmit the target data based on the cellular network.

Optionally, for a situation that the cellular network state change notification also carries the base station identifier of the currently connected first base station, the corresponding processing procedure in step 104 may be as follows: when receiving target data sent by a terminal, an AP sends a shunting message to the terminal if the current load is greater than a preset number threshold, the cellular network available state information is currently available, and the data transmission capability of a first base station meets a preset transmission condition.

The data transmission capability of the first base station may include a frame loss rate, a data delay, a service quality capacity, and the like.

In implementation, if the current load amount is greater than the preset number threshold and the cellular network availability status information is currently available, it may further be determined whether the data transmission capability of the first base station to which the terminal is currently connected meets the preset transmission condition. If the current load amount is greater than the preset number threshold, the cellular network available state information is currently available, and the data transmission capability of the first base station meets the preset transmission condition, the AP may send a shunting message to the terminal, for instructing the terminal to transmit the target data based on the cellular network. The AP may determine whether the data transmission capability of the first base station meets a preset transmission condition according to the base station identifier of the first base station currently connected, which is sent by the terminal. Specifically, the AP may search for the base station identifier of the first base station in a base station identifier list that is pre-stored and has data transmission capability satisfying a preset transmission condition, and may send the offloading message to the terminal if the base station identifier of the first base station is found. The specific method for storing the base station identification list will be described in detail later.

In step 105, the terminal transmits the target data based on the cellular network when receiving the offload message sent by the AP.

In implementation, after the AP sends the offload message, the terminal may receive the offload message sent by the AP, and further, may transmit the target data to the base station through the cellular network, so that the base station transmits the target data to the server.

In addition, after the terminal transmits the target data based on the cellular network, when the target data fails to be transmitted based on the cellular network, a data transmission failure notification may be further sent to the AP so that the AP processes the target data. The process flow shown in fig. 4 will be described in detail below with reference to the embodiments, and the contents may be as follows:

in step 401, the terminal transmits a data transmission failure notification to the AP when the target data fails to be transmitted based on the cellular network.

In step 402, the AP controls transmission of target data upon receiving a data transmission failure notification sent by the terminal.

Optionally, based on different processing manners of the AP on the target data, the processing procedure of step 202 may be various, and several feasible processing manners are given below:

in the first mode, the AP transmits target data.

Accordingly, for the first mode, the specific processing procedure of step 402 may be as follows: and when receiving the data transmission failure notice sent by the terminal, the AP sends the target data.

In implementation, after receiving the data transmission failure notification sent by the terminal, the AP does not send a offload message to the terminal, but continues to transmit the target data through WiFi.

In the second mode, the AP determines a second base station with data transmission capacity meeting the preset transmission condition in the base stations with which the terminal can be connected; and sending a base station switching message to the terminal, wherein the base station switching message carries the base station identifier of the second base station.

In implementation, after the terminal sends the data transmission failure notification, the AP may randomly select a second base station to which the terminal is connectable from a pre-stored list of base station identifiers whose data transmission capabilities satisfy the preset transmission conditions. Since the AP and the base station can be connected in the same core network, the AP can obtain the base station identification of the base station to which the terminal can connect from the core network.

And after determining a second base station with data transmission capacity meeting the preset transmission condition, the AP sends a base station switching message to the terminal, wherein the base station switching message carries a base station identifier of the second base station and is used for indicating the terminal to be switched and connected to the second base station. For example, when the terminal fails to transmit the target data through the base station 1 based on the cellular network, the terminal transmits a data transmission failure notification to the AP and informs the AP that the base station to which the terminal is currently connected is the base station 1. When receiving a data transmission failure notification sent by a terminal, the AP randomly selects a base station 2 having data transmission capability satisfying a preset transmission condition from base stations connectable to the terminal, sends a base station switching message to the terminal, instructs the terminal to switch to connect to the base station 2, and transmits target data based on a cellular network.

Optionally, for a situation that the AP sends a base station switching message to the terminal, correspondingly, the terminal may further perform the following processing: and the terminal receives the base station switching message sent by the AP, switches to be connected to the second base station, and transmits the target data based on the cellular network. And the base station switching message carries the base station identifier of the second base station. The base station handover message is used to instruct the terminal to handover to the second base station.

In an implementation, the terminal may disconnect from the first base station, switch to connect to the second base station, and transmit the target data to the second base station through the cellular network after receiving the base station switching message, so that the second base station transmits the target data to the server.

Optionally, for the second mode, the data transmission failure notification may also carry a transmission failure reason.

The transmission failure reason may include: the first base station refuses the access of the terminal, 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 the preset threshold, the service quality capacity of the first base station is less than the preset threshold, the terminal receives the signal of the first base station weakly, the interference is greater than the preset threshold when the terminal receives the signal of the first base station, the service requested by the terminal is unavailable, and the like.

Correspondingly, for the case that the data transmission failure notification may also carry the reason for the transmission failure, the AP may further perform the processing procedure shown in fig. 5, which includes the following specific contents:

in step 501, if the transmission failure reason is caused by the data transmission capability of the first base station to which the terminal is currently connected, the AP marks that the data transmission capability of the first base station does not satisfy the preset transmission condition.

The case that the transmission failure reason is caused by the data transmission capability of the first base station to which the terminal is currently connected 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 the preset threshold, the service quality capacity of the first base station is less than the preset threshold, and the like.

In implementation, after the AP receives a data transmission failure notification sent by the terminal, if a transmission failure reason sent by the terminal is a reason caused by the data transmission capability of the first base station to which the terminal is currently connected, such as that a frame loss rate of the first base station is greater than a preset threshold, a data delay of the first base station is greater than the preset threshold, and a capacity of service quality of the first base station is less than the preset threshold, the AP may mark that the data transmission capability of the first base station does not satisfy a preset transmission condition, where a base station identifier of the first base station to which the terminal is currently connected may be carried in the data transmission failure notification or carried in the available state change notification of the cellular network. Specifically, if the base station identifier of the first base station currently exists in the base station identifier list whose data transmission capability satisfies the preset transmission condition, the AP may delete the base station identifier of the first base station from the base station identifier list.

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

In implementation, after the AP marks that the data transmission capability of the first base station does not satisfy the preset transmission condition, the AP may detect, from the core network, the data transmission capability corresponding to the first base station, such as a frame loss rate, a data delay, a capacity of service quality, and the like.

In step 503, when detecting that the data transmission capability of the first base station satisfies the preset transmission condition, the AP marks that the data transmission capability of the first base station satisfies the preset transmission condition.

In implementation, after detecting the data transmission capability of the first base station, the AP may compare the data transmission capability with the preset transmission condition, and when detecting that the data transmission capability of the first base station satisfies the preset transmission condition, the AP may mark that the data transmission capability of the first base station satisfies the preset transmission condition, that is, add the base station identifier of the first base station to the base station identifier list whose data transmission capability satisfies the preset transmission condition, so as to facilitate subsequent use. The condition that the AP detects that the data transmission capability of the first base station satisfies the preset transmission condition may be: the AP detects that the frame loss rate of the first base station is smaller than a preset threshold, the AP detects that the data delay of the first base station is smaller than the preset threshold, the AP detects that the service quality capacity of the first base station is larger than the preset threshold, and the like.

In the embodiment of the disclosure, when the load capacity of the AP is greater than the preset number threshold, the AP may send the shunt message to the terminal, the terminal transmits the target data based on the cellular network after receiving the shunt message, and the terminal does not need to send the target data through the AP with a large load capacity, so that the data transmission efficiency may be improved. And before the AP sends the shunting message, the AP can know that the terminal can use the cellular network currently, and then the AP sends the shunting message to the terminal under the condition that the terminal can use the cellular network currently, so that the success rate of data transmission based on the cellular network can be improved.

An exemplary embodiment of the present disclosure also provides a method for transmitting data, which may be implemented by a terminal and a WiFi AP together. The terminal may be a smart phone, a smart watch, a tablet computer, or other devices that may use WiFi and a cellular network, and the AP may be a wireless network access point deployed by each large operator, such as a router.

The transceiver may be configured to send targeted data, send cellular network state change notifications, send data transmission failure notifications, receive offload messages, receive base station handover messages. The memory may be a RAM, a Flash, etc., and may be used for storing received data, data required by the processing procedure, data generated in the processing procedure, etc., such as target data, cellular network status change notification, data transmission failure notification, etc.

The transceiver may be configured to receive target data, receive a cellular network state change notification, receive a data transmission failure notification, send a offload message, send a base station switch message, and so on. The memory may be a RAM, a Flash, or the like, and may be configured to store received data, data required by a processing procedure, data generated during the processing procedure, or the like, such as target data, a cellular network status change notification, a data transmission failure notification, a data transmission capability of a marked base station, or the like.

The process flow shown in fig. 6 will be described in detail below with reference to the embodiments, and the contents may be as follows:

in step 601, the terminal transmits target data to an access point AP of WiFi.

The target data is data to be transmitted through the AP.

Optionally, when the terminal changes the available state of the cellular network, the terminal may further send a notification of the change of the available state of the cellular network to the AP, and correspondingly, the terminal may further perform the following processing: the terminal may send a cellular network availability status change notification to the AP when detecting that the availability status of the cellular network has changed.

The cellular network availability status change notification carries cellular network availability status information, which is used for indicating whether the terminal can use the cellular network currently. The situation that the available state of the cellular network changes may include that the terminal reconnects to the cellular network (specifically, the terminal reconnects to the cellular network of the same radio access technology as that before disconnection), or that the terminal switches to another base station when connecting to the cellular network (specifically, the terminal switches to another base station of the same radio access technology as that of the source base station when connecting to the cellular network), or that the terminal disconnects from the cellular network.

In an implementation, when the terminal detects that a cellular network is reconnected, or when the terminal switches to another base station while connecting to the cellular network (specifically, when the terminal detects that a cellular network of the same radio access technology as that before the disconnection is reconnected, or switches to another base station while connecting to the cellular network), a cellular network availability status change notification may be sent to the AP, where in this case, the cellular network availability status change notification may carry cellular network availability status information indicating that the terminal may currently use the cellular network, so as to inform the AP that the terminal may currently use the cellular network. When detecting that the terminal is disconnected from the cellular network, the terminal may send a cellular network available state change notification to the AP, and in this case, the cellular network available state change notification may carry cellular network available state information used to indicate that the terminal does not use the cellular network currently, and be used to notify the AP that the terminal does not use the cellular network currently.

In step 602, the AP receives target data transmitted by the terminal.

In implementation, after the terminal transmits the target data to the AP, the AP may transmit the target data to the server when the AP may receive the target data transmitted by the terminal.

In step 603, if the current load is greater than the preset number threshold, a shunting message is sent to the terminal.

The offloading message is used for instructing the terminal to transmit the target data based on the cellular network.

In implementation, after receiving the target data sent by the terminal, the AP may compare the current load amount with a preset number threshold. If the current load amount of the AP is greater than the preset number threshold, a offload message may be sent to the terminal for instructing the terminal to transmit the target data based on the cellular network.

Optionally, for a case that the terminal may send a notification of change of the available state of the cellular network to the AP when detecting that the available state of the cellular network changes, the AP may further perform the following processing: and receiving a cellular network available state change notification sent by the terminal, wherein the cellular network available state information is carried in the cellular network state change notification. Accordingly, the specific processing procedure of step 603 may be as follows: and if the current load is greater than the preset number threshold and the cellular network available state information is currently available, sending a shunting message to the first terminal.

Optionally, the cellular network state change notification further carries a base station identifier of the currently connected first base station. Correspondingly, for the case that the cellular network state change notification also carries the base station identifier of the currently connected first base station, the specific processing procedure of step 603 may be as follows: and if the current load is greater than the preset number threshold, the cellular network available state information is currently available, and the data transmission capability of the first base station meets the preset transmission condition, sending a shunting message to the terminal.

In step 604, the terminal transmits the target data based on the cellular network when receiving the offload message sent by the AP.

In implementation, after the AP sends the offloading message, the terminal may receive the offloading message sent by the AP, and further, may transmit the target data to the base station through the cellular network, so that the base station transmits the target data to the server.

In step 605, the terminal transmits a data transmission failure notification to the AP when the target data fails to be transmitted based on the cellular network.

The failure of the target data transmission based on the cellular network may be caused by the terminal itself, or may be caused by the data transmission capability of the first base station to which the terminal is currently connected.

In an implementation, after the terminal transmits the target data based on the cellular network, when the target data fails to be transmitted based on the cellular network, the terminal may transmit a data transmission failure notification to the AP so that the AP processes the target data.

In step 606, the AP controls transmission of target data when receiving a data transmission failure notification sent by the terminal.

Optionally, based on different processing manners of the AP on the target data, the processing procedure of step 606 may be various, and several feasible processing manners are given below:

in the first mode, the AP transmits target data.

Correspondingly, for the first mode, the specific processing procedure of step 606 may be as follows: and when receiving the data transmission failure notice sent by the terminal, the AP sends the target data.

In the second mode, the AP determines a second base station with data transmission capacity meeting preset transmission conditions in base stations which can be connected with the terminal; and sending a base station switching message to the terminal, wherein the base station switching message carries the base station identifier of the second base station.

In an implementation, after the terminal sends the data transmission failure notification, the AP may randomly select a second base station to which the terminal is connectable from a pre-stored list of base station identifiers whose data transmission capabilities satisfy the preset transmission conditions. Since the AP and the base station can be connected in the same core network, the AP can obtain the base station identification of the base station to which the terminal can connect from the core network.

In an implementation, the terminal may disconnect from the first base station, switch to connect to the second base station, and transmit the target data to the second base station through the cellular network after receiving the base station handover message, so that the second base station transmits the target data to the server.

Correspondingly, for the case that the data transmission failure notification may also carry the reason for the transmission failure, the AP may further perform the processing procedure shown in fig. 7, which includes the following specific contents:

in step 701, if the transmission failure reason is caused by the data transmission capability of the first base station to which the terminal is currently connected, the AP marks that the data transmission capability of the first base station does not satisfy the preset transmission condition.

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

In step 703, when detecting that the data transmission capability of the first base station satisfies the preset transmission condition, the AP marks that the data transmission capability of the first base station satisfies the preset transmission condition.

In implementation, after detecting the data transmission capability of the first base station, the AP may compare the data transmission capability with the preset transmission condition, and when detecting that the data transmission capability of the first base station satisfies the preset transmission condition, the AP may mark that the data transmission capability of the first base station satisfies the preset transmission condition, that is, add the base station identifier of the first base station to the base station identifier list whose data transmission capability satisfies the preset transmission condition, so as to facilitate subsequent use. The condition that the AP detects that the data transmission capability of the first base station meets the preset transmission condition may be: the AP detects that the frame loss rate of the first base station is smaller than a preset threshold, the AP detects that the data delay of the first base station is smaller than the preset threshold, and the AP detects that the service quality capacity of the first base station is larger than the preset threshold.

In the embodiment of the disclosure, after receiving the target data sent by the AP, if the load capacity of the AP is greater than the preset number threshold, the AP may send the shunt message to the terminal, and after receiving the shunt message, the terminal transmits the target data based on the cellular network, and the terminal does not need to send the target data through the AP with a large load capacity, thereby improving the data transmission efficiency. And after the target data fails to be transmitted based on the cellular network, the terminal can inform the AP of the data transmission failure, and under the condition, the AP can control the transmission of the target data again, so that the accuracy and the success rate of the data transmission based on the cellular network can be improved.
