The process has no network break, and the process of re-distributing the network is not needed, so that the stability of the network can be improved.
In an embodiment, as shown in fig. 2, a method for distributing a network with multiple hot spots is provided, which is described by taking the method as an example for being applied to the terminal device in fig. 1, and includes the following steps:
step 202, when a first network card of the terminal device is connected with a first WIFI hotspot and the first network card is used for network connection of the terminal device, detecting network performance of each WIFI hotspot in the multi-hotspot set, wherein the first WIFI hotspot is a WIFI hotspot in the multi-hotspot set.
Here, the terminal device is a WIFI terminal device, and the terminal device at least includes a first network card and a second network card, and the first network card and the second network card can realize different functions at different times. The function here may be a main network card function or a monitoring network card function. When the first network card is used for network connection of the terminal device, the first network card realizes the function of a main network card. Generally, when the first network card is used for network connection of the terminal device, the first network card is used for information interaction between the terminal device and a server (for example, a cloud) or other terminal devices.
Here, multiple WIFI hotspots may be included in the multi-hotspot set.
Specifically, the terminal device may detect the network performance of each WIFI hotspot in the multi-hotspot set on the second network card, or may detect the network performance of each WIFI hotspot in the multi-hotspot set on other modules or other devices of the terminal device. The network performance parameters can be determined according to actual needs. The network performance of each WIFI hotspot in the multi-hotspot set may be detected periodically (i.e., in a round).
And 204, connecting a second network card of the terminal device with a second WIFI hotspot, wherein the second WIFI hotspot is a WIFI hotspot with the best current network performance in the remaining WIFI hotspots, and the remaining WIFI hotspots are WIFI hotspots in the multi-hotspot set except the first WIFI hotspot.
For example, there are 5 WIFI hotspots in the multi-hotspot set, such as F1, F2, F3, F4, and F5, and if the first WIFI hotspot is F2, the remaining WIFI hotspots are 4 WIFI hotspots, such as F1, F3, F4, and F5.
Specifically, the terminal device compares network performance parameters of each remaining WIFI hotspot in the network performance detection result, screens a WIFI hotspot with the best current network performance from the remaining WIFI hotspots, takes the screened WIFI hotspot as a second WIFI hotspot, and connects a second network card of the terminal device to the second WIFI hotspot. And the second network card can also execute the processes of comparing the network performance parameters of all the remaining WIFI hotspots, screening the WIFI hotspots, connecting with the second WIFI hotspot and the like.
And step 206, when the network performance parameters of the first WIFI hotspot do not meet the preset first network connection condition, switching to network connection of the terminal equipment through the second network card.
Here, the first network connection condition refers to a condition that a corresponding WIFI hotspot is suitable for network connection, and may be set according to actual needs, for example, a value of the network performance parameter is greater than (or not less than) a first threshold, and a size of the first threshold may be set according to actual needs.
Specifically, when the network performance parameter of the first WIFI hotspot does not meet the preset first network connection condition, the terminal device switches to network connection of the terminal device through the second network card. When the network connection of the terminal device is switched to be performed through the second network card, the second network card is used for realizing the function of the main network card so as to be used for information interaction between the terminal device and a server (such as a cloud) or other terminal devices, and the first network card (the main network card before switching) plays a role in monitoring the network card. Or when the network performance parameter of the second network card at the first WIFI hotspot does not meet the preset first network connection condition, switching to network connection of the terminal device through the second network card.
In the multi-hotspot network distribution method, when a first network card of a terminal device is connected with a first WIFI hotspot and the first network card is used for network connection of the terminal device, the network performance of each WIFI hotspot in a multi-hotspot set is detected, a second network card of the terminal device is connected with a second WIFI hotspot, the second WIFI hotspot is a WIFI hotspot with the best current network performance in the remaining WIFI hotspots, and when the network performance parameter of the first WIFI hotspot does not meet a preset first network connection condition, network connection of the terminal device is switched to be performed through the second network card. Because the terminal device of this embodiment includes at least first network card and second network card, and when first network card connects first WIFI hotspot and first network card is used for terminal device's network connection, terminal device's second network card connects second WIFI hotspot, so, when the network performance of first WIFI hotspot does not satisfy the requirement, need not carry out the distribution network process again, can directly, switch over the WIFI hotspot fast, the efficiency and the smoothness of hotspot switch have been improved, the time delay is low, can promote network stability.
In an embodiment, as shown in fig. 3, a method for distributing a network with multiple hot spots is provided, which is described by taking the method as an example for being applied to the terminal device in fig. 1, and includes the following steps:
step 302, receiving hotspot information of a plurality of WIFI hotspots sent by the distribution network device, where the plurality of WIFI hotspots are used as each WIFI hotspot in the multi-hotspot set.
Here, the network distribution device may be a mobile terminal or a non-mobile terminal, the non-mobile terminal includes a desktop computer, and the mobile terminal may be, but is not limited to, a Smart Phone (Smart Phone), a tablet computer, a notebook computer, a personal digital assistant, and the like. The distribution network device serves as an STA (Station, wireless terminal mode), and is in communication connection with the terminal device through the WIFI network. The terminal device serves as an AP (Wireless Access Point).
And step 304, storing hotspot information of a plurality of WIFI hotspots.
Here, the hotspot information generally includes WIFI hotspot identification and password information of the corresponding WIFI hotspot. The WIFI hotspot Identifier generally refers to an SSID (Service Set Identifier).
Specifically, the terminal device may store the hotspot information of the multiple WIFI hotspots in a local memory. The hotspot information may be stored in the local memory in the form of a database (or a data table of the database).
And step 306, screening the WIFI hotspot with the best current network performance from the plurality of WIFI hotspots, and taking the selected WIFI hotspot as a first WIFI hotspot.
Here, the first WIFI hotspot is screened out of a plurality of WIFI hotspots in which hotspot information is stored.
Specifically, the terminal device may detect network performances of a plurality of WIFI hotspots in which hotspot information is stored, filter a plurality of WIFI hotspots with the best current network performance, and use the selected WIFI hotspots as first WIFI hotspots.
And 308, controlling the first network card to be connected with the first WIFI hotspot according to the hotspot information of the first WIFI hotspot.
Specifically, the terminal device controls the first network card to connect to the first WIFI hotspot according to hotspot information of the first WIFI hotspot, and the first network card is used as a main network card for communication between the terminal device and a server (such as a cloud) or other terminal devices.
The above steps 302-308 can be executed on the first network card, or can be executed on other modules or other devices (e.g. a processor) of the terminal device.
Step 310, when a first network card of the terminal device is connected with a first WIFI hotspot and the first network card is used for network connection of the terminal device, detecting network performance of each WIFI hotspot in the multi-hotspot set, wherein the first WIFI hotspot is a WIFI hotspot in the multi-hotspot set.
And step 312, connecting a second network card of the terminal device to a second WIFI hotspot, where the second WIFI hotspot is a WIFI hotspot with the best current network performance in the remaining WIFI hotspots, and the remaining WIFI hotspots are WIFI hotspots in the multi-hotspot set except the first WIFI hotspot.
The round of determining the network performance parameters according to the second WIFI hotspot may be the same as or different from the round of determining the network performance parameters according to the first WIFI hotspot. For example, in the first round of network performance detection, the WIFI hotspot with the best network performance is taken as a first WIFI hotspot, the WIFI hotspot with the second best network performance is taken as a second WIFI hotspot, in the second round of network performance detection, the WIFI hotspot with the best network performance in the remaining WIFI hotspots is taken as a second WIFI hotspot, in the third round of network performance detection, the WIFI hotspot with the best network performance in the remaining WIFI hotspots is taken as a second WIFI hotspot, and so on.
Specifically, the server controls the first network card to connect with the first WIFI hotspot according to hotspot information of the first WIFI hotspot
And step 314, when the network performance parameter of the first WIFI hotspot does not meet the preset first network connection condition, switching to network connection of the terminal device through the second network card.
The description of step 310, step 312 and step 314 in this embodiment may refer to the description in the previous embodiment, and is not repeated herein.
By adopting the scheme of the embodiment, the network performance of the WIFI hotspot connected with the network card with the main network card function can be optimal as much as possible, and meanwhile, the network does not need to be re-distributed when the router is switched to be connected, so that the network stability can be improved compared with the situation of a single network card.
In one embodiment, the method for distributing a network with multiple hot spots further includes the following steps: and when the WIFI hotspots meeting the preset second network connection condition exist in the remaining WIFI hotspots according to the last round of network performance detection results of the remaining WIFI hotspots, determining the WIFI hotspot with the best current network performance in the remaining WIFI hotspots according to the last round of network performance detection results.
Here, the previous round refers to a round that is closest in time to the current time and has traversed the network performance detection of each WIFI hotspot in the multi-hotspot set.
Here, the second network connection condition refers to a condition that the corresponding WIFI hotspot is suitable for network connection, and may be set according to actual needs, for example, a value of the network performance parameter is greater than (or not less than) a second threshold, and a size of the second threshold may be set according to actual needs. The second threshold may be equal to, greater than or less than the first threshold, preferably the second threshold is greater than or equal to the first threshold.
When the last round of network performance detection results determine that no WIFI hotspot meeting the preset second network connection condition exists in the remaining WIFI hotspots, waiting for the end of the current round of network performance detection, and determining the WIFI hotspot with the best current network performance and the network performance parameter meeting the preset second network connection condition in the remaining WIFI hotspots as the WIFI hotspot with the best current network performance in the remaining WIFI hotspots according to the current round of network performance detection results of the remaining WIFI hotspots. If it is determined that no WIFI hotspot meeting the preset second network connection condition still exists in the remaining WIFI hotspots according to the network performance detection result of the current round, continuing to wait for the network performance detection result of the next round, and so on until a WIFI hotspot meeting the preset second network connection condition exists in one round, and determining the WIFI hotspot with the best current network performance in the remaining WIFI hotspots.
In this embodiment, when there is a WIFI hotspot meeting the preset second network connection condition in the remaining WIFI hotspots, the WIFI hotspot with the best current network performance in the remaining WIFI hotspots is determined according to the network performance detection result of the previous round, so that it is avoided that the network performance of the switched WIFI hotspot still does not meet the networking condition.
In one embodiment, as shown in fig. 4, the detecting the network performance of each WIFI hotspot in the multi-hotspot set may include the following steps:
step 402, detecting the network speed value, the network delay information and the signal strength information of each WIFI hotspot in the multi-hotspot set.
The signal strength information can be acquired through a self-contained interface of the network card chip, for example, the interface of the application layer system software network card chip supporting the WIFI function terminal can acquire the signal strength information in real time. The request packet may be sent through the second network card, the network delay information may be determined by a time interval from sending the request packet to receiving the reply packet, and the network speed value may be obtained by a time taken to download a file of a specified size.
In addition, the network speed value, the packet loss rate and the signal strength information of each WIFI hotspot in the multi-hotspot set may also be detected.
And the packet loss rate is calculated according to the number ratio of the reply packets to the request packets.
And step 404, respectively determining network performance parameters of each WIFI hotspot in the multi-hotspot set according to the network speed value, the network delay information and the signal strength information.
In addition, network performance parameters of each WIFI hotspot in the multi-hotspot set may also be determined according to the network speed value, the packet loss rate, and the signal strength information.
Wherein, the network performance optimization generally means that the value of the network performance parameter is the maximum.
Specifically, the network speed score value can be determined according to the network speed value, the network delay score value is determined according to the network delay information, the signal strength score value is determined according to the signal strength information, and the network speed score value, the network delay score value and the signal strength score value are weighted and summed to obtain the network performance parameters of each WIFI hotspot in the hotspot set. Or, the network speed score value can be determined according to the network speed value, the packet loss score value is determined according to the packet loss rate, the signal strength score value is determined according to the signal strength information, and the network speed score value, the packet loss score value and the signal strength score value are subjected to weighted summation to obtain the network performance parameters.
The network speed, the network delay (or the packet loss rate), and the signal strength may be scored by comparing with corresponding reference values, for example, a ratio of the network speed value to the network speed reference value may be calculated, and then the network speed score value may be determined according to the ratio (for example, multiplied by 100).
For example, equation (1) may be used to calculate the WIFI hotspots in the multi-hotspot set.
Figure BDA0002339131840000111
Wherein, αi、βiAnd gammaiRespectively representing the network speed score value, the network delay score value (or the packet loss score value) and the signal strength score value, lambda of the ith WIFI hotspot1、λ2And λ3For the weighted value, the size of the weighted value can be set according to the actual network environment. In addition, network performance parameters of each WIFI hotspot in the multi-hotspot set can also be determined according to the network speed value, the packet loss rate and the signal strength information.
In this embodiment, different from a traditional WIFI switching mode based on only WIFI strength, information in multiple aspects such as network speed, network delay (or packet loss rate), signal strength and the like is comprehensively considered, so that a switched WIFI hotspot is more suitable for networking of terminal equipment.
In one embodiment, the method for distributing a network with multiple hot spots further includes the following steps: and when the network performance parameters of the WIFI hotspots with the best network performance in the current turn in the multi-hotspot set are smaller than a preset threshold value, or when the network performance parameters of the WIFI hotspots with the best network performance in the continuous turns in the multi-hotspot set are all smaller than the preset threshold value, sending prompt information to the distribution network equipment.
Here, specific values of the plurality of rounds may be set according to actual conditions, for example, 3 rounds.
The user can adjust the hotspot information of the WIFI hotspot stored by the terminal device in time based on the prompt information, and the stored hotspot information can be deleted, added or updated.
