Detailed

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that, in the case of no conflict, the features in the embodiments and the embodiments herein may be arbitrarily combined with each other.

The steps illustrated in the flowchart of the figures may be executed in a computer system in accordance with a set of computer executable instructions. Also, although logical sequences are shown in the flowcharts, in some cases the steps shown or described may be performed in a different order than the ones described herein.

In order to solve the problem that the currently connected access point in the related art is degraded due to users or other factors, the terminal cannot automatically switch from the current access point to the access point with better network quality for service transmission, thereby reducing the user. For a problem of the experience, the embodiment of the present invention provides a method for switching a wireless access point. Referring to FIG. 1, FIG. 1 is a schematic diagram of a wireless access point according to an embodiment of the present invention. For a flowchart of the method, the method for switching the wireless access point includes the following steps, namely, S110 to S130:

S110. Establish a communication connection with at least two wireless access points that meet the access condition by using at least two network cards configured.

In the embodiment of the present invention, at least two network cards may be configured in advance for the terminal. Optionally, at least two network cards configured in the embodiment of the present invention may be a wireless network card; or at least two virtual network cards virtualized by one wireless network card, thereby establishing a communication connection with the access point through the virtual network card to implement services. transmission.

Optionally, in the embodiment of the present invention, the network card and the wireless access point may have a one-to-one correspondence, wherein at least one network card is configured as a working network card, and the remaining at least one network card is configured as a standby network card. In practical applications, if the user does not enable the automatic network selection function, the terminal will not detect the available wireless access points in the real-time through the network card, and the corresponding communication connection will not be established with the wireless access point. Therefore, the communication connection is established. The premise is that the user turns on the automatic network selection function, or the terminal automatically turns on the function.

Optionally, the access condition in the embodiment of the present invention refers to a wireless access point that can cover the terminal and can be normally connected, and each configured network card establishes a communication connection with the one-to-one corresponding wireless access point, in actual In the application, one wireless access point can also correspond to multiple network cards, and each network card communicates with the same wireless access point. In addition, at least one network card of the configured network card is set as a working network card, and at least one of the remaining network cards is set as a standby network card, the working network card is used for service transmission, and the communication connection is maintained; the standby network card also maintains a communication connection, but is not used for transmission service. When the working network card network quality is poor, the working network card is switched to the standby network card, and the original standby network card is switched to the working network card, and the service network card continues to transmit the service, because the working network card (that is, the standby network card before the switching) is always held. Communication connection, and only the state of the network card is switched (that is, the working network card is switched to the standby network card, and the standby network card is switched to the working network card), so that the subsequent service is directly transmitted through the switched working network card and its corresponding wireless access point, thereby The maximum guarantee that the terminal service will not be interrupted due to the switching of the access point.

S120: Each network card separately detects network quality of a wireless access point corresponding to the network card.

In the embodiment of the present invention, the configured at least two network cards respectively detect the network quality of the wireless access point corresponding thereto, and select one wireless access point to perform handover according to the detected network quality. The network quality is the quality of service communication between the wireless access point and the target server, that is, each network card check The quality of the communication between the wireless access point and the target server is measured. In practical applications, the network quality may also be the quality of service communication between the wireless access point and the network card.

Optionally, the implementation manner of S120 in the embodiment of the present invention may include: each network card separately detecting one of a network delay, a packet loss rate, a theoretical bandwidth, and an actual bandwidth of a wireless access point corresponding to the network card. Multiple. In the embodiment of the present invention, network quality is measured by network quality detection indicators such as network delay, packet loss rate, theoretical bandwidth, and actual bandwidth, so as to ensure that the selected wireless access point is the access point with the best connection quality, thereby maximizing the degree. The network after the handover is guaranteed to be the optimal network.

S130: Determine the network quality detected by each network card as one of the determining factors, determine the preset switching condition, determine the working network card and the standby network card to be switched, and complete the switching according to the determination result.

In the embodiment of the present invention, the network quality is evaluated, for example, by network detection indicators such as network delay, packet loss rate, theoretical bandwidth, and actual bandwidth, to determine whether the network quality of the wireless access point corresponding to the backup network card is currently connected. The wireless access point network is of good quality, providing more efficient data for network switching.

The wireless access point switching method provided by the embodiment of the present invention establishes a communication connection with at least two wireless access points that meet the access condition by using at least two network cards, wherein at least one network card is set as a working network card, and at least one other network card is configured. Set as the standby network card; each network card detects the network quality of the wireless access point corresponding to the network card, and determines the network quality detected by each network card as one of the determining factors, determines the preset switching condition, and determines the work to be switched. The network card and the backup network card are used to complete the handover according to the judgment result. In the embodiment of the present invention, the terminal can automatically switch to the access point with better network quality to perform service transmission when the network quality of the currently connected access point is deteriorated. In addition, in the process of network switching, since each network card and the access point have established a communication connection, only the state of the network card needs to be switched, for example, the working network card is switched to the standby network card, and the standby network card is switched to the working network card, and the communication does not need to be reestablished. Connection, you can ensure that the terminal's business will not be cut as much as possible. Interrupted, so as to enhance the user experience.

Optionally, in the embodiment of the present invention, the foregoing preset switching condition may include: the network quality detected by the at least one standby network card is better than the network quality detected by the at least one working network card. That is to say, the network quality is used as one of the determining factors to determine the preset switching condition, that is, according to the network quality and other determining factors, whether the network quality of the wireless access point corresponding to the standby network card is better than the wireless access corresponding to the working network card. The network quality of the point. In practical applications, it is not necessary to require an alternate network card. The network quality of the wireless access point is better than the network quality of the wireless access point corresponding to the current working network card, as long as the network quality of the wireless access point corresponding to the standby network card is better than the network quality of the wireless access point corresponding to the current working network card. For example, the packet loss rate of the wireless access point corresponding to the current working network card is low, but the network delay, the actual bandwidth, and the theoretical bandwidth are both poor, and the network delay of the wireless access point corresponding to one network card in the standby network card, The actual bandwidth is better than the network delay and actual bandwidth of the current wireless access point, but the packet loss rate is higher than the current packet loss rate of the wireless access point; in the case where the packet loss rate is not high, the The network quality of the wireless access point corresponding to the backup network card is better than the network quality of the current wireless access point. Therefore, the measurement indicators such as the network quality of each wireless access point can be comprehensively considered, and the most suitable wireless access point can be selected for switching. At the same time, when switching, the actual switch is the network card, that is, the current working network card is switched to the standby network card, and the standby network card to be switched is switched to the working network card for service transmission, so as to ensure that the service of the terminal is not caused by the network card to the greatest extent. Switched and interrupted.

Optionally, before performing the handover of the network card, the embodiment of the present invention may also consider whether the terminal currently performs continuous network services such as downloading. If the continuous network service is performed, the network service may be temporarily interrupted, and the network connection is automatically Continue to complete the download. Although the wireless access point switching method provided by the implementation of the present invention can ensure that the service is not interrupted by the network switching to the greatest extent, it still has a small impact on the continuous network service, and therefore, the continuous network is not downloaded. In the case of services, for the application, the network performs fast switching in the background, and the temporary interruption of the network is basically invisible to the user, so that the user has a good use experience.

Optionally, in S110 of the embodiment of the present invention, the working network card includes at least one, and the service network card also includes at least one. When the working network card includes at least two, when some network cards in the working network card have a network quality deterioration, the network quality may be deteriorated. Select the corresponding number of network cards from the standby network card to switch to replace the original working network card for the transmission service. You only need to switch the original working network card to the standby network card and switch the standby network card to be transmitted to the working network card. It should be noted that, regardless of the backup network card and the working network card, the communication connection is always established with the corresponding wireless access point, and is in a standby state capable of performing service transmission at any time, and once the network quality is detected is better than the network corresponding to the wireless access point of the current working network card. When the quality of the backup network card is used, the subsequent service directly transmits the service through the switched standby network card, thereby maximally avoiding the network interruption caused by switching from the current wireless access point to the next wireless access point.

Optionally, FIG. 2 is a flowchart of another method for switching a wireless access point according to an embodiment of the present invention. In the embodiment of the present invention, in addition to detecting the network quality, the signal quality may be detected, such as detecting the signal strength of each wireless access point. The method provided by the embodiment of the present invention may further include the following steps, that is, S140 to S160:

S140: Each network card separately detects a signal quality of a wireless access point corresponding to the network card;

S150. Determine, according to the signal quality detected by each network card, whether the signal quality detected by the at least one standby network card is better than the signal quality detected by the at least one working network card.

S160. When it is determined that the signal quality detected by the at least one standby network card is better than the signal quality detected by the at least one working network card, determine the working network card and the standby network card to be switched, and complete the handover.

In the embodiment of the present invention, the signal quality may be a service communication quality parameter between the wireless access point and the target server, and it is determined by the signal quality which wireless access point in each wireless access point has better connection quality. The quality of the currently connected wireless access point connection, so as to more accurately select an optimal wireless access point for network switching for more efficient data. After each network card detects the signal quality of the corresponding wireless access point, it is determined according to the signal quality detected by each network card whether there is at least one standby network card detecting signal quality better than at least one working network card detecting signal quality, when there is at least When the signal quality detected by an alternate network card is better than the signal quality detected by at least one working network card, the working network card and the standby network card to be switched are determined and the switching is completed, that is, the network card that needs to be switched, for example, which working network card needs to be switched to standby. As an alternative, the NIC needs to be switched to a working NIC for subsequent service transmission.

Optionally, in the embodiment of the present invention, the foregoing preset switching condition includes: the network quality detected by the at least one standby network card is better than the network quality detected by the at least one working network card. When there is a network quality better than the at least one working network card detection in the network quality detected by the backup network card, the network card is used as the standby network card to be switched, and the standby network card to be switched is switched to any one of the working network card replacement working network cards, or according to The priority is replaced. When there are at least two network qualities better than the at least one working network card detection in the network quality detected by the backup network card, any one of the network qualities is used as the standby network card to be switched, and the standby network card is switched to work. The NIC replaces any one of the working NICs or replaces them according to priority.

Optionally, in the embodiment of the present invention, for the network quality and the signal quality, the connection quality of the wireless access point is comprehensively evaluated according to the two dimensions, and the wireless access point with good network quality is not a letter. The quality of the number is good. Similarly, the wireless access point with good signal quality is not good in network quality. The overall better is the first choice for network switching, that is, the network quality and signal quality of the wireless access point to be switched are in the whole wireless. Although the access point is not optimal, the overall connection quality of the two is better than other wireless access points. Therefore, when performing network switching, a suitable wireless access point is comprehensively evaluated for handover. For the same reason, for other judgment factors, it can also be used as a criterion for judging the connection quality of wireless access points.

Optionally, in the embodiment of the present invention, when the current wireless access point includes an unconnected wireless access point, the method provided by the embodiment of the present invention may further include: determining, according to the preset enabling condition, that the unconnected Whether the wireless access point can establish a communication connection with the network card; in the case where the communication connection can be established, communication is established by the at least two network cards with the already connected wireless access point and the wireless access point satisfying the enabling condition. In practical applications, considering that an unconnected wireless access point (including an unconnected open wireless access point) may have a security risk, a setting item may be added to the terminal to set whether to allow the terminal to try to connect without being connected. The wireless access point, when the function is enabled, establishes a communication connection with the wireless access point through the network card, thereby ensuring the automatic switching of the wireless access point with better network quality. User information is secure.

Based on the wireless access point switching method provided by the embodiment of the present invention, the terminal can automatically switch from an access point with poor network quality to an access point with better network quality, and at the same time, can ensure that the service of the terminal is not caused by the network to the utmost extent. Switching and interrupting greatly enhances the user experience.

Based on the wireless access point switching method provided by the foregoing embodiment of the present invention, a home scene is taken as an example to describe a wireless access point switching method in detail. In this scenario, the user has two wireless access point wireless access points (APs) 1 and AP2, which are placed in the living room and the study room, and the terminals are connected. The current AP1 corresponds. The working network card, AP2 corresponds to the standby network card, and the working network card and the standby network card are virtual network cards created by a wireless network card. The switching of the wireless access point is implemented based on the scenario. Referring to FIG. 3, FIG. 3 is a schematic diagram of a handover scenario of the method for switching a wireless access point according to the embodiment. The handover process in the application scenario is as follows:

The terminal is currently connected to the AP1 in the U1 location of the AP1 coverage area. The user currently watches the TV through the application (Application: APP) on the terminal in the living room. At this time, the terminal uses the working network card (wlan1) to connect to the AP1. The corresponding APP also goes online through AP1. In the case that the user sets the automatic selection network to be on, the terminal detects the surrounding available wireless access points in real time, around The available wireless access point is AP2, and the terminal in the U1 position is also in the coverage of AP2. The terminal creates a standby network card (wlan2) through the wireless network card, and attempts to connect to AP2 using wlan2. However, since the signal strength of AP2 is detected to be weaker than that of AP1, AP2 is not used as a working network card for service transmission, but is used as a backup network card to connect to AP2 and detect the network quality of AP2.

The user now moves from the living room to the study to read the book, as shown by the black arrow in the figure, the black arrow indicates the user's movement track, and the user moves to the U2 position of the AP2 coverage. As the user moves in the direction of AP2, the signal strength of AP1 is gradually weakened, and the signal strength of AP2 is gradually enhanced. The working network card (wlan1) and the standby network card (wlan2) respectively detect the network quality of AP1 and AP2, for example, detecting both. The network delay, packet loss rate, ideal bandwidth, and actual bandwidth are evaluated by the above indicators. The network quality of AP2 is better than that of AP1. In addition, the signal quality of AP2 is better than AP1 due to user mobility. Signal quality. In the actual application, it is also possible to detect whether the current terminal performs a connection network service such as downloading, and if the continuous network service is not performed, the standby network card (wlan2) corresponding to the AP2 is switched to the working network card (wlan2), and the AP1 is connected. The corresponding working network card (wlan1) is switched to the standby network card (wlan1), and the working states of wlan1 and wlan2 are switched, and the work is switched to standby, and the standby is switched to work. For the application on the terminal, the network performs fast switching in the background. In the case of non-continuous network services, the temporary interruption of the network is basically invisible to the user.

It should be noted that both the working network card and the standby network card according to the embodiment of the present invention establish a communication connection with the corresponding wireless access points AP1 and AP2 in advance, and then the working network card performs service transmission, and the standby network card does not perform service transmission. However, it is also in the state of maintaining communication, and the service can be transmitted as needed. While the backup network card detects the network quality of the corresponding wireless access point AP2, AP1 also performs network quality detection during the service transmission process, and finally comprehensively evaluates the network quality of AP1 and AP2 to determine whether to perform network switching, so that the user obtains more Good network experience.

The wireless access point switching method provided by the embodiment of the present invention determines a wireless access point with the best connection quality by comprehensively evaluating the network quality and signal quality of each wireless access point, and switches the state of the network card through the network card. Quickly switch the network to avoid re-establishing the communication connection after the handover, so as to ensure that the terminal service is not interrupted due to network switching.

Based on the wireless access point switching method provided by the foregoing embodiment of the present invention, the shopping mall scene is The method of wireless access point switching is described in detail. In this scenario, there are two wireless access points, AP1 and AP2, and both access point terminals have been connected. The current AP1 corresponds to the working network card, and the AP2 corresponds to the standby network card. The working network card and the standby network card are virtual network cards created by a wireless network card. The switching process of the wireless access point is implemented based on the scenario. Referring to FIG. 4, FIG. 4 is a schematic diagram of another switching scenario of the wireless access point switching method according to the embodiment. The switching process in the application scenario is as follows:

The terminal is currently in the U1 position in the coverage area of AP1. It is detected that the signal strength of other nearby wireless access points AP2 is close to that of AP1. The terminal first connects to AP1 using the working network card (wlan1). In the case that the user sets the automatic selection network to be on, the terminal detects the available wireless access points in real time, and the surrounding available wireless access points are AP2, and the terminals in the U1 position are also in the coverage of AP2, and the terminal is created through the wireless network card. An alternate NIC (wlan2) and try to connect to AP2 using wlan2. Because the signal strengths of AP1 and AP2 are similar, the terminal does not switch the status of the working network card (wlan1) corresponding to AP1, that is, the working network card is not switched to the standby network card.

The number of users connected to the AP1 wireless access point in the shopping mall is increasing. Although the signal strength of the AP1 is close to that of the AP2, the working network card (wlan1) detects the packet loss rate and network delay of the corresponding AP1. The network quality value is obviously increased, and the network quality value such as the packet loss rate and network delay of the corresponding AP2 is still at a reasonable level, from the signal strength, network delay, packet loss rate, and ideal. A plurality of indicators, such as bandwidth and actual bandwidth, are comprehensively evaluated for AP1 and AP2, and the connection quality of AP2 is better than that of AP1. In Figure 4, the current coverage of AP1 is connected to four terminals, which are A1, A2, A3, and A4. The U1 is connected to A1; the current coverage of AP2 is only connected to one terminal A5, because AP1 is connected. The number of terminals is significantly higher than that of AP2. Correspondingly, the AP1 packet loss rate and network delay are significantly higher than AP2, so that the network quality of AP1 is lower than that of AP2.

Therefore, under the premise of ensuring that the terminal does not perform continuous network services such as downloading, the working network card (wlan1) corresponding to AP1 is switched to the standby network card (wlan1) for preparation for subsequent network switching, and the standby network card (wlan2) is switched to The working network card (wlan2) continues the subsequent service transmission. After the NIC is switched, the subsequent service directly transmits the service to the wireless access point AP2 through the working network card (wlan2), thereby avoiding re-establishing the communication connection with the wireless access point AP2, resulting in a long interruption of the network. For the application on the terminal, the network performs fast switching in the background. In the case of non-continuous network services, the temporary interruption of the network is basically invisible to the user.
