Detailed Description

The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.

The first embodiment is as follows:

referring to fig. 1, the present embodiment provides a method for switching between bluetooth and WiFi, where a client side actively initiates switching between connection modes of a wireless access point network, so as to implement seamless switching between bluetooth and WiFi on the client side, and when a requirement of the client on a network rate is low, the client side can switch to a bluetooth mode to connect to the wireless access point network (commonly called a hotspot). The method for switching between bluetooth and WiFi in this embodiment includes:

s101, acquiring an original connection mode and a corresponding network load of a wireless access point network currently connected with a client; wherein, the corresponding network load (i.e. the network load of the wireless access point network to which the client is currently connected) is used for representing the data service quality of the client in the original connection mode of the wireless access point network;

s102, acquiring a switching threshold corresponding to an original connection mode according to a preset switching threshold corresponding to each connection mode of the wireless access point network; the connection mode of the wireless access point network comprises a WiFi mode and a Bluetooth mode;

s103, if the logic relation between the corresponding network load and the switching threshold value corresponding to the original connection mode meets the switching condition, switching the original connection mode of the wireless access point network.

The method of this embodiment is to actively initiate switching of network connection modes at a client side, where initiation of a switching process is determined by the client itself, and the client of this embodiment may be a handheld terminal and a wearable device, such as an electronic device like a smart phone, a tablet computer, a smart watch, or a computer with a WiFi module and a bluetooth module. The wireless Access Point (AP) providing a wireless Access Point (AP) network may be an intelligent terminal, and further may be an intelligent terminal of the same type as the client, and further, the wireless Access Point device may provide different network connection modes for a plurality of clients at the same time.

In this embodiment, the client has a WiFi module and a bluetooth module, which can respectively provide a WiFi connection mode and a bluetooth connection mode with the wireless access point network. Naturally, in this embodiment, the WiFi module and the bluetooth module may be two separately configured modules, or may be a two-in-one synthesis module. In S101, the connection mode between the client and the wireless access point network may be a WiFi mode or a bluetooth mode. When the wireless access point network is connected, the step S101 may be performed to obtain the original connection mode of the current wireless access point network of the client and the corresponding network load. It is understood that the original connection mode may be a bluetooth mode or a WiFi mode, or other connection modes other than WiFi and bluetooth that can connect to the wireless access point network.

In this embodiment, in order to improve the experience of the user using the client, the WiFi mode may be set as a default access mode. When a user needs to use a client to access the wireless access point network for surfing the internet, the user firstly accesses the wireless access point network for surfing the internet in a wifi mode, after the wifi access is successful, the process of S101-S102 is carried out at intervals to judge the current network flow, and if the current network load is lower than a preset switching threshold value corresponding to the Bluetooth mode, the started Bluetooth related process and service are started.

In S101, the network load corresponding to the current wireless access point network of the client is used to reflect whether the current wireless access point network meets the requirement for the user in the current original connection mode, and how much the network speed resource is redundant on the basis of meeting the requirement. Further, the network load is data which is acquired by the client and is related to the data service quality of the client, the network load can reflect the requirement of the client on the real-time network rate in the original connection mode, when the client is in the use states of browsing a webpage, swiping a microblog and the like, the requirement of the data service on the network rate is not high, the Bluetooth connection mode can generally meet the requirement of the client, when the client is in the use states of video playing, large-scale games and the like, the requirement of the data service of the client on the network rate is generally high, in view of the fact that the maximum network rate which can be provided by a wireless access point network in the common Bluetooth connection mode is about 1Mbps (the actual maximum rate can be determined according to specific equipment), and at the moment, the WiFi mode can more easily meet the requirement of the client.

In view of that the network rate of the wireless access point network to which the client is connected may reflect the data service quality of the client to some extent, in this embodiment, the network load may be the network rate of the wireless access point network to which the client is connected.

Assuming that the original connection mode of the client currently connecting to the wireless access point network is the WiFi mode, the handover threshold corresponding to the WiFi mode may be set as the network rate that can be provided in the bluetooth access mode. The network rate that can be provided in the bluetooth access mode may be a maximum rate in the bluetooth access mode, and in order to ensure network quality after switching to the bluetooth access mode, the network rate that can be provided in the bluetooth access mode may be set to data that is lower than the maximum network rate. Supposing that the maximum network rate in the bluetooth mode is 1Mbps, after the network rate of the client in the WiFi mode is obtained, comparing the maximum network rate with 1Mbps, if the maximum network rate exceeds the switching threshold, the bluetooth mode still cannot meet the requirements of the current client, switching is not needed currently, if the network rate of the client is lower than 1Mbps, the bluetooth mode is very likely to meet the requirements of data services of the client, and considering that the power consumption of the client in the WiFi mode is higher than that in the Bluetooth mode, on the basis of the consideration of reducing the power consumption of the client, the judgment result is that the connection mode of the wireless access point network of the client needs to be switched.

Assuming that the original connection mode of the current wireless access point network connected by the client is the bluetooth mode, the switching threshold corresponding to the bluetooth mode may be set to the maximum rate in the bluetooth mode, for example, 1Mbps/s, after the network rate of the client in the bluetooth mode is obtained, the switching threshold is compared with 1Mbps/s, if the obtained network rate is about 1Mbps/s, the network rate is obtained for several times, if the obtained network rates are all about 1Mbps/s, it is indicated that the requirement of the current data service on the network rate may be high, the bluetooth mode may not meet the requirement of the current client, and the determination result is that the connection mode of the wireless access point network of the client needs to be switched.

Of course, it is expected that the network rate itself is limited by the access mode, and it is not very accurate to use 1mbps/s in the bluetooth mode as a condition, and it needs to be combined with other data to judge more accurately.

Preferably, the network load in S101 of this embodiment includes: and under the original connection mode of the current wireless access point network, the delay percentage of the data packet transmitted in the unit time of the network layer. It is foreseen that, if the client is currently in a data uploading state, the delay percentage is a delay percentage of a data packet uploaded by the client, and if the client is in a data downloading state, the delay percentage may be understood as a delay percentage of a data packet sent by a network layer received by the client. The handover threshold corresponding to each connection mode indicates a requirement that the network load needs to meet in each connection mode. The switching threshold corresponding to the WiFi connection mode is a judgment basis for judging whether the network load in the current WiFi mode meets the requirement or not and whether the WiFi connection mode needs to be switched to the bluetooth connection mode or not, and the network load corresponding to the bluetooth connection mode is a judgment basis for judging whether the network load in the current bluetooth mode meets the requirement or not and whether the bluetooth connection mode needs to be switched to the WiFi connection mode or not.

The following explains the process of S103, taking the current original connection mode of the client as WiFi mode and bluetooth mode as examples.

When the current original connection mode of the client is the WiFi mode, judging whether the network load of the wireless access point network currently connected with the client does not exceed a switching threshold corresponding to the WiFi mode or not according to the network load of the wireless access point network currently connected with the client and a preset switching threshold corresponding to the WiFi mode, and if so, switching the connection mode of the wireless access point network currently required by the client.

It is envisioned that switching WiFi to bluetooth, typically at the current client's data traffic, will require lower network rates than the wireless access point network can provide in a WiFi mode. At this time, the current network flow is small, the delay of the network data packet is generally low, and the current network can also meet the client requirements in a low-speed mode. Therefore, as for the switching threshold corresponding to the WiFi mode, what is reflected is a condition that the delay percentage of the data packet transmitted in unit time needs to meet when the WiFi mode is switched to the bluetooth mode, generally, the delay percentage is lower than the first threshold, where the first threshold may be set according to the strict degree of the requirement on the network quality, and may be set to 1%, that is, the delay percentage of the data packet transmitted in unit time is not more than 1% of the total number of the data packet, and certainly, other reasonable probabilities may also be set, which is not limited in this embodiment.

Of course, the above-mentioned determination method may also be combined with the determination method of the network rate, in S103, when the delay percentage of the data packets transmitted in the unit time in the original connection mode is lower than the first threshold of the total number of the data packets, the network rate in the original connection mode is determined again, and when the network rate is also lower than the maximum rate in the bluetooth mode, the WiFi mode is switched to the bluetooth mode. The above combination is for illustration, and the combination of the two determination conditions is not limited at all.

And secondly, when the original connection mode is a Bluetooth mode, judging whether the network load of the wireless access point network currently connected with the client is not lower than a switching threshold value according to the network load of the wireless access point network currently connected with the client and a preset switching threshold value corresponding to the Bluetooth mode, if so, switching the connection mode of the wireless access point network currently required by the client.

For example, when a user is watching a screen, playing a network tour, and the like, the network speed provided by the bluetooth connection mode may not bring good experience, the delay probability of a data packet sent by a network layer in unit time is generally high, and the screen or the network tour may be blocked, which may cause poor experience for the user. Therefore, for the switching threshold corresponding to the bluetooth connection mode, the probability of the time delay of the data packet of the network in unit time is set to be higher than the second threshold of the total number of the data packets, and since the probability of the time delay of the data packet transmitted by the network layer in unit time is more than 50%, a relatively obvious pause phenomenon occurs, 50% can be used as the second threshold. And when the retransmission probability of the data packets of the internal network among the units is more than 50%, switching from the Bluetooth connection mode to the WiFi connection mode. Of course, in this embodiment, the second threshold may be freely set according to the actual situation or the actual need of the user, when the requirement of the user on the network rate is higher, the second threshold may be set to be lower than 50% of data, and when the tolerance of the user on the network congestion is higher, the second threshold may be set to be higher than 50% of data, which is not limited in this embodiment.

After the above determination, if it is necessary to switch the connection mode, considering that in an area where the client is located, if there is coverage of multiple wireless access point networks, there may be multiple wireless access point networks for the client to select, and network signals of the multiple wireless access point networks have strong or weak, and the client may also select a wireless access point network connection with a stronger network signal when switching the connection mode.

Therefore, the switching of the connection mode of the wireless access point network in S103 includes the following two modes:

the first method is as follows: and when the number of the wireless access point networks which can be accessed by the client is multiple, selecting one wireless access point network from the multiple wireless access point networks as a target network, and connecting the target network according to the switched connection mode.

For a general intelligent terminal, such as a smart phone, a tablet, etc., connectable wireless access point networks can be searched, and the wireless access point networks can be ranked according to the strength of network signals, so this embodiment may select a wireless access point network with the strongest signal from a plurality of networks for connection according to the signal strength of the plurality of wireless access point networks acquired by the client itself, the selected result may be the currently connected wireless access point network or other accessible networks, and the specific selection result may be determined according to actual situations.

If other accessible networks are selected, in order to realize seamless switching of the two connection modes as much as possible and reduce the downtime caused by network switching, the wireless access point network can be connected with the other accessible networks first and then disconnected, and certainly, it is also feasible to disconnect the current network and then connect the other networks. It should be noted that after the handover, the connection mode for connecting the wireless access point network is different from the original access mode.

During switching, the user may be using operations that cannot be interrupted, such as online payment, and if switching is performed, poor experience or more serious economic loss may be brought to the user. The prompting mode includes, but is not limited to, a voice prompt, a prompt box displayed on a display screen, and the like.

If the selected wireless access point network is the current network, refer to the detailed handover procedure related in the following second method.

The second method comprises the following steps: and when the wireless access point network which can be accessed by the client is the current wireless access point network, switching the original connection mode of the current wireless access point network into the corresponding connection mode.

The switching of the access mode of the current wireless access point network to the corresponding connection mode comprises switching from a WiFi mode to a Bluetooth mode and switching from the Bluetooth mode to the WiFi mode.

If the original connection mode of the current wireless access point is the WiFi mode, the current wireless access point needs to be switched to the bluetooth mode, and in view of low power consumption for starting the bluetooth, the bluetooth function of a general wireless access point device is always started, so the client can directly start to discover the bluetooth device (the wireless access point device for starting the bluetooth) after determining that the connection mode needs to be changed. Then, the service of the communicable Bluetooth device is inquired, the channel number of the related information RFCOMM is obtained, then the client initiates an RFCOMM connection request to establish connection of the RFCOMM, and after the wireless access point device receives the connection request and responds, the client establishes application docking with the wireless access point device. When application docking is established, the wireless access point routes synchronously switch the network mode from the WiFi mode to the Bluetooth mode, and then for the wireless access point equipment, data of the client from a subsequent network layer are sent out through a Bluetooth module of the wireless access point equipment, and for the client, the internet is accessed through the Bluetooth mode.

In order to minimize the network interruption time, the network mode of the wireless access point device may be switched from WiFi to bluetooth after the bluetooth connection between the client and the wireless access point device (whether the current wireless access point device or the selected other wireless access point device) is established.

If the original connection mode of the current wireless access point is the Bluetooth mode, switching to the WiFi mode is needed. During switching, the MAC address of the wireless access point device (whether the current wireless access point device or the selected other wireless access point device) may be obtained first, and whether the wireless access point device is connected before is determined, if so, the wireless access point device may be directly connected without inputting a password from the client. At this time, the client can disconnect the Bluetooth connection first and then switch to the WiFi mode immediately, and the corresponding wireless access point equipment only needs to accept the WiFi connection of the client. If the wireless access point device is not connected before, the corresponding password needs to be accessed (no password is directly connected), and the four-way handshake of the WiFi connection is completed, so that the WiFi can be connected. Therefore, in order to reduce the time occupied by network interruption caused by switching of the network connection mode of the client, the wireless access point device can switch the route from the Bluetooth mode to the WiFi mode after establishing WiFi connection with the client. Thereafter, data from the network layer is passed out of the WiFi for use by the client. For the client, a WiFi connection may be established with the wireless access point device and then a bluetooth connection may be disconnected.

Further, in order to reduce the power consumption of the client, only one of the WiFi module and the bluetooth module may be turned on for service at the same time.

In this embodiment, the switching of the connection mode of the wireless access point network is performed based on the power consumption of the client, and in S103, the switching is performed based on a logical relationship between a network load of the client and a preset switching threshold, where the network load includes a delay percentage of a transmission packet in a unit time of a network layer corresponding to the current client. In addition, how to judge the switching of the connection mode of the wireless access point network can be considered from other points of view, for example, considering from the aspects of the use scene of the client, the access content and the like, for the use scene needing high network speed such as watching a video screen, playing a game and the like, the use scene needing a WiFi mode can be divided, for the use scene needing low network speed such as swiping a web page, watching a novel and the like, the use scene needing a bluetooth mode can be divided. When the connection mode is switched, the current use scene of the client is matched with the divided use scenes, and if the matching is successful, the wireless access point network is connected according to the corresponding connection mode (the switching may be carried out or not).

For the access content, data services such as video and games which need a large number of pictures can be divided into access content which needs a WiFi mode, and for web pages which do not contain video and have low requirements for network speed, access content which needs a bluetooth mode can be divided. When judging whether to switch the connection mode, the current access content of the client is matched with the divided access content, and if the matching is successful, the wireless access point network is connected according to the corresponding connection mode (possibly switching or not).

In addition, the remaining power of the client can be used as a standard for switching, and when the remaining power of the client is below a warning value, the connection mode of the wireless access point network can be switched to a Bluetooth mode.

The above-mentioned determination method based on network load, access content, usage scenario, network rate and remaining power of the client may be appropriately and organically combined to obtain a more comprehensive and detailed determination rule, and the combination method is not limited in this embodiment.

For the client, the current network rate cannot be detected every moment under the condition that the wireless access point network is accessed. Therefore, the bottom layer will detect the current network rate in the interval time, which is specifically the average value of the time intervals of the last three handovers. For example, the first three times are approximately switched once in 5 hours, so the device bottom layer automatically detects the network load situation 5 hours away from the last switching, and determines whether the switching condition is satisfied. Therefore, in order to make the switching of the wireless access point network more reasonable, in S101, the current network load of the client may be obtained according to a preset time interval; and then the subsequent judgment processing flow is carried out. Wherein the preset time interval is updated according to the historical time interval.

In order to enable the user to further participate in the handover process, the present embodiment may write an application program for the client, provide a selection interface of network connection modes (WiFi mode and bluetooth mode), and specifically describe each connection mode, for example, a supported use scenario, access content, and a supported maximum network speed. Therefore, the user can switch automatically according to the use scene and the like, which is manual switching of the user, and of course, the embodiment also supports automatic switching of the client, wherein the priority of switching set by the user is higher than that of automatic switching of the client. It is foreseen that the preset time interval is not fixed, but is updated in time according to the frequency and period of the user manual switching and the client automatic switching.

By adopting the switching method of bluetooth and WiFi in this embodiment, the original mode of the wireless access point network currently connected to the client and the corresponding network load in the connection mode are obtained, and then, in combination with the preset switching threshold corresponding to each connection mode of the wireless access point network, whether the logical relationship between the network load and the corresponding switching threshold meets the condition for switching the original connection mode is determined, and switching is performed when the logical relationship meets the condition. Compared with the prior art in which the switching between the data network and the WiFi is performed only in consideration of the charge, the switching to the Bluetooth mode with lower power consumption can be performed when the requirement of the client on the network rate is low, so that the electric quantity is saved, the cruising ability of the client is enhanced, the power consumption and the standby function of a terminal product are optimized, and a high-quality and careful service is provided for a user.

Example two:

referring to fig. 2, this embodiment shows another method for switching between bluetooth and WiFi, where a wireless access point device actively initiates switching of a connection mode of a wireless access point network, and the wireless access point device may determine whether the connection mode of the wireless access point network is switched, when the switching is required, a client may be controlled to implement seamless switching between bluetooth and WiFi, when a client has a low requirement on a network rate, the client may be switched to a bluetooth mode to connect the wireless access point network (commonly called a hotspot), when the client meets the requirement on the network rate, the use of a bluetooth mode with low power consumption is beneficial to reducing power consumption of the client, and extends standby time, so as to bring better experience to the client, and when the client has a high requirement on the network rate, the client may be switched to a WiFi mode to connect the wireless access point network.

S201, acquiring a current connection mode and a corresponding network load of at least one client connected with a wireless access point network of the wireless access point equipment at the wireless access point equipment side; the corresponding network load is used for representing the data service quality of the client under the original connection mode of the wireless access point network;

s202, acquiring a switching threshold corresponding to an original connection mode of each client according to a preset switching threshold corresponding to each connection mode of the wireless access point network; the connection mode of the wireless access point network comprises a WiFi mode and a Bluetooth mode;

s203, if the logic relation between the network load corresponding to a certain client and the switching threshold corresponding to the original connection mode of the client meets the switching condition; and sending a switching prompt message to the corresponding client.

The above-mentioned S201 to 203 may be all performed by a wireless access point device, where the wireless access point device may be any device that can share the AP network in a WiFi manner or a bluetooth manner, such as a mobile phone, a tablet, a computer, and the like, and the client in this embodiment is a device that shares the AP network in a WiFi manner or a bluetooth manner, such as an electronic device that is a mobile phone, a tablet, a desktop computer, a smart watch, a smart bracelet, and the like. This is not intended to be limiting in any way.

In this embodiment, the wireless access point device has a WiFi module and a bluetooth module, which can respectively provide a network for the client to connect to itself in a WiFi mode and a bluetooth mode. Naturally, in this embodiment, the WiFi module and the bluetooth module may be separate modules, or may be a two-in-one synthesis module. In S201, the connection mode between the client and the wireless access point network may be a WiFi mode or a bluetooth mode. Certainly, for a wireless access point device, it may provide a wireless access point network for multiple clients at the same time, and the connection mode of each client to the wireless access point network may be different, that is, at the same time, two clients may be connected to the same wireless access point device through WiFi and bluetooth modes respectively to share the network of the device. In view of the low power consumption of the bluetooth mode, generally, both WiFi and bluetooth are turned on simultaneously on the wireless access point device.

Therefore, it can be understood that in S201, the original connection mode may be a bluetooth mode and/or a WiFi mode, or other connection modes besides WiFi and bluetooth that can connect to the wireless access point network.

In S201, the network load corresponding to the current wireless access point network of the client is used to reflect whether the current wireless access point network meets the requirement for the user in the current original connection mode, and how much the network speed resource is redundant on the basis of meeting the requirement. The network load can reflect the requirement of a client on the real-time network rate in an original connection mode, when the client is in a use state of browsing a webpage, swiping a microblog and the like, the requirement of a data service on the network rate is not high, the Bluetooth connection mode can generally meet the requirement of the client, when the client is in a use state of video playing, large-scale games and the like, the requirement of the data service of the client on the network rate is generally higher, and in view of the fact that the maximum network rate which can be provided by a wireless access point network in the common Bluetooth connection mode is about 1Mbps (the actual maximum rate can be determined according to specific equipment), the WiFi mode can more easily meet the requirement of the client at the moment.

Preferably, the network load corresponding to each client in the original connection mode in this embodiment includes: and in the original connection mode of the current wireless access point network, the delay percentage of the data packet transmitted in the unit time of the network layer is reduced. The switching threshold corresponding to each connection mode indicates that the network load needs to meet the requirement under each connection mode, and each client has a corresponding network load. And the network load corresponding to each client is generally different due to the difference of the use state and the connection mode of each client. The handover threshold corresponding to each connection mode indicates a requirement that the network load needs to meet in each connection mode.

For the wireless access point device, the determination process is different when the original connection mode of the client is different.

If the original connection mode is a WiFi mode, judging whether the network load of the wireless access point network currently connected with the client does not exceed a switching threshold value according to the network load of the wireless access point network currently connected with the client and a preset switching threshold value corresponding to the WiFi mode, and if so, switching the connection mode of the wireless access point network currently required by the client.

It is envisioned that switching WiFi to bluetooth, typically the data traffic at the connected client, will require a lower network rate than the wireless access point network can provide in the WiFi mode. At this time, the current network flow of the client is small, the time delay of the network data packet of the client is generally low, and the current network can meet the requirements of the client in a low-speed mode. Therefore, as for the switching threshold corresponding to the WiFi mode, what is reflected is a condition that the delay percentage of the data packet transmitted in unit time needs to be satisfied when the WiFi mode is switched to the bluetooth mode, generally, the delay percentage is lower than the first threshold, where the first threshold may be set according to the strict degree of the requirement on the network quality, and may be set to 1%, that is, the delay percentage of the data packet transmitted (received or transmitted) in unit time by the network layer is not more than 1% of the total number of the data packet, and the client currently needs to perform the switching of the original connection mode of the wireless access point network. Of course, other reasonable probabilities may be set, and this embodiment does not limit this.

If the original connection mode is a Bluetooth mode, judging whether the network load of the wireless access point network currently connected with the client is not lower than a switching threshold value according to the network load of the wireless access point network currently connected with the client and a preset switching threshold value corresponding to the Bluetooth mode, and if so, switching the connection mode of the wireless access point network currently required by the client.

For example, when a user is watching a screen, playing a network tour and the like, the network speed provided by the bluetooth connection mode may not bring good experience, the delay probability of a data packet transmitted by a network layer in unit time is generally high, the screen or the network tour may be blocked, and bad experience is brought to the user. Therefore, for the switching threshold corresponding to the bluetooth connection mode, the delay (or retransmission) probability of the network packet in unit time may be set to be higher than the second threshold of the total number of the data packets, and since the delay probability of the data packet sent by the network layer in unit time is more than 50%, a relatively obvious pause phenomenon occurs, so 50% may be used as the second threshold. And when the probability of the data packet delay of the network in the units is more than 50%, switching from the Bluetooth connection mode to the WiFi connection mode. Of course, in this embodiment, the second threshold may be freely set according to the actual situation or the actual need of the user, when the requirement of the user on the network rate is higher, the second threshold may be set to be lower than 50% of data, and when the tolerance of the user on the network congestion is higher, the second threshold may be set to be higher than 50% of data, which is not limited in this embodiment.

After the original connection mode of the client needs to be switched, the control command can be selected to be sent to the client, and the client executes the control command to complete the switching of the connection mode of the client. Preferably, after it is determined that the original connection mode of the client needs to be switched, a switching prompt message is generally sent to the corresponding client (the client that needs to switch the connection mode), so as to prompt the user that the connection mode can be switched currently, and corresponding processing is performed according to a response of the client.

After S203, the method for switching between bluetooth and WiFi at the client side includes: receiving switching prompt information sent by wireless access point equipment which is connected with the wireless access point equipment through a wireless access point network; and responding to the switching prompt message according to the selection of the user. When the user selects the handover, the client initiates a handover procedure, and the specific handover procedure may refer to the related description of the first embodiment. When the user chooses not to switch, the client side does not need to perform any feedback, and when the wireless access point equipment does not receive any feedback within a certain time, the wireless access point equipment can be considered to abandon the switching.

In view that the network rate of the wireless access point network to which the client is connected may reflect the data service quality of the client to a certain extent, in this embodiment, the network load may also be defined as the network rate of the wireless access point network to which the client is connected.

Assuming that the original connection mode of the client currently connecting to the wireless access point network is the WiFi mode, the handover threshold corresponding to the WiFi mode may be set as the network rate that can be provided in the bluetooth access mode. The network rate that can be provided in the bluetooth access mode may be a maximum rate in the bluetooth access mode, and in order to ensure network quality after switching to the bluetooth access mode, the network rate that can be provided in the bluetooth access mode may be set to data that is lower than the maximum network rate. Supposing that the maximum network rate in the bluetooth mode is 1Mbps/s, after the network rate of the client in the WiFi mode is obtained, comparing the maximum network rate with 1Mbps/s, if the maximum network rate exceeds the switching threshold value, the bluetooth mode still cannot meet the requirements of the current client, the switching is not needed at present, if the network rate of the client is lower than 1Mbps/s, the bluetooth mode is very likely to meet the requirements of data services of the client, and considering that the power consumption of the client in the WiFi mode is higher than that in the Bluetooth mode, the corresponding judgment result is to switch the connection mode of the wireless access point network of the client based on the consideration of reducing the power consumption of the client.

Assuming that the original connection mode of the current wireless access point network connected by the client is the bluetooth mode, the switching threshold corresponding to the bluetooth mode may be set to the maximum rate in the bluetooth mode, for example, 1Mbps/s, after the network rate of the client in the bluetooth mode is obtained, the switching threshold is compared with 1Mbps/s, if the obtained network rate is about 1Mbps/s, the network rate is obtained for several times, if the obtained network rates are all about 1Mbps/s, it is indicated that the requirement of the current data service on the network rate may be high, the bluetooth mode may not meet the requirement of the current client, and the connection mode of the wireless access point network of the client needs to be switched.

In this embodiment, the switching of the connection mode of the wireless access point network is performed based on the network load of the client and a preset switching threshold in consideration of the power consumption of the client. In addition, how to judge whether the original connection mode of the client needs to be switched or not can be considered from other points of view, for example, the use scenes of the client, the access content and the like are considered, the use scenes which need high network speed such as watching a video screen, playing a game and the like can be divided into the use scenes which need a WiFi mode, and the use scenes which do not need high network speed such as swiping a webpage, watching a novel and the like can be divided into the use scenes which need a bluetooth mode. When the connection mode is judged to be switched, the wireless access point equipment only needs to match the current use scene of the client with the divided use scenes, and if the matching is successful, the wireless access point equipment is connected with the wireless access point network according to the corresponding connection mode (the switching may be carried out or not).

For the access content, data services such as video and games which need a large number of pictures can be divided into access content which needs a WiFi mode, and for web pages which do not contain video and have low requirements for network speed, access content which needs a bluetooth mode can be divided. When judging whether to switch the connection mode, the wireless access point equipment only needs to match the current access content of the client with the divided access content, and if the matching is successful, the wireless access point equipment is connected with the wireless access point network according to the corresponding connection mode (possibly switching or not switching).

The above-mentioned determination method based on network load, access content, usage scenario, and network rate may be combined appropriately and organically to obtain a more comprehensive and detailed determination rule, and the combination method is not limited in this embodiment.

For the client, the current network rate cannot be detected every moment under the condition that the wireless access point network is accessed. Therefore, the bottom layer will detect the current network rate in the interval time, which is specifically the average value of the time intervals of the last three handovers. For example, the first three times are approximately switched once in 5 hours, so the device bottom layer automatically detects the network load situation 5 hours away from the last switching, and determines whether the switching condition is satisfied. Therefore, in order to make the switching of the wireless access point network more reasonable, the wireless access point device can obtain the current network load of the client according to the preset time interval; and then the subsequent judgment processing flow is carried out. Wherein the preset time interval is updated according to the historical time interval. The historical time interval here may be a time interval of the last few times, such as the last 3 times, the last 5 times, etc.

By adopting the switching method of the Bluetooth and the WiFi, whether the connection mode with the client needs to be switched or not can be judged on the wireless access point equipment side, and the WiFi mode is switched to the low-power-consumption Bluetooth mode under the condition that the data service quality is not influenced, so that the power consumption of the client is effectively reduced, the electric quantity is saved, the cruising ability of the client is enhanced, the power consumption and the standby function of a terminal product are optimized, and higher-quality service is provided for users.

When the client is under the coverage of a plurality of AP networks, the first switching module can switch according to the actual situation. Further, the first switching module 323 is configured to, when there are multiple wireless access point networks accessible to the client, select one of the multiple wireless access point networks as a target network, and connect to the target network according to a switched connection manner; and when the wireless access point network which can be accessed by the client is the current wireless access point network, switching the original connection mode of the current wireless access point network into the corresponding connection mode.

The wireless access point device can switch the route after the client side opens the connection mode different from the original connection mode.

By adopting the bluetooth and WiFi switching system of this embodiment, the client can obtain the original mode of the wireless access point network currently connected to the client and the corresponding network load in the connection mode, and then determine whether the logical relationship between the network load and the corresponding switching threshold satisfies the switching condition in combination with the preset switching threshold corresponding to each connection mode of the wireless access point network, if so, perform the switching of the connection mode, and the corresponding wireless access point device can perform corresponding switching according to the information of the client.
