Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.
The network access method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
In the prior art, when a terminal device performs wireless connection in a public WIFI environment, all BSSIDs in the current WIFI environment are scanned, and each BSSID corresponds to a Received Signal Strength Indication (RSSI). And after the scanning is finished, selecting BSSID corresponding to the strongest RSSI for connection.
In this case, if the number of terminal devices connected in the public WIFI environment is large, a plurality of terminal devices may be simultaneously connected to an AP of one BSSID, which may further cause the following problems:
first, the load of a single Ap is high. The higher load causes the overall delay of the Ap when forwarding various data packets to be increased, and even abnormal phenomena such as packet loss, no forwarding, slow forwarding, wrong forwarding and the like occur, which causes unnecessary retransmission in the network and reduces the network smoothness rate of the terminal device.
Second, the average bandwidth and throughput rate are lower. It will be appreciated that the average bandwidth of the end devices is equal to the total bandwidth divided by the number of connected end devices. Since a large number of connections of a single Ap will result in a low average bandwidth of all wireless terminals below the Ap, especially in a scenario such as video and download, which requires a high throughput, the average bandwidth is significantly affected.
And thirdly, the WIFI second-layer link has large competition. Because all wireless terminal users are connected with the same BSSID, and the Ap corresponding to the BSSID only works in one channel, only one wireless device can transmit or receive a packet in the same time period according to a specified competition strategy, and other devices have to retreat back to wait for the next time slot in which the packet can be transmitted or received. Therefore, the more devices working in the same channel, the longer the backoff waiting time is, and the time delay of the whole terminal device below the Ap is increased.
The average bandwidth and the uplink and downlink throughput rate of each terminal device connected to the AP device are low.
The embodiment of the present application provides a network access method to solve the above problem.
And configuring the broadcasted beacon frame and the device connection information at the AP device. The terminal equipment scans the beacon frame of the AP equipment in a public WIFI environment, and then determines equipment connection information. And the terminal equipment performs comprehensive judgment through the equipment connection information and the signal intensity information and selects one AP equipment for connection. The AP equipment updates the equipment connection information after being connected with the terminal equipment, so that the equipment connection information received by other terminal equipment is changed, and then other AP equipment is selected when the other terminal equipment carries out comprehensive judgment according to the connection information and the signal intensity information. By the method, the quantity balance of the terminal equipment connected with each AP equipment in the plurality of AP equipment is realized, the condition that one AP equipment is connected with too many terminal equipment is avoided, the average bandwidth and the uplink and downlink throughput rate of the terminal equipment are further improved, and the time delay is reduced.
The network access method provided by the embodiment of the present application is described in detail below with respect to a terminal and an access point device.
Referring to fig. 1, fig. 1 is a flowchart of a network access method provided in an embodiment of the present application, which is executed by a terminal device, and as shown in fig. 1, the method includes the following steps:
step S101, receiving beacon frames broadcasted by at least two access point devices, wherein the beacon frames comprise device connection information of the access point devices, and the device connection information is used for representing the number of connected terminal devices of the access point devices.
The device connection Information is Downlink Control Information (DCI). The device connection information is used to characterize the terminal device conditions to which the access point device is connected, i.e. including the number of connected terminal devices.
It should be understood that the WIFI to which the terminal device is connected is divided into a home personal AP and a public network AP. The terminal Device may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or a vehicle-mounted Device. When the terminal equipment starts to be connected, firstly, the indication information is continuously received or the WIFI environment is scanned, and the current public WIFI environment is determined. After determining that the current access point device is in the public WIFI environment, the terminal device scans and confirms BSSIDs of all AP devices, and records DCI information and RSSI information corresponding to each BSSID, that is, receives a beacon frame broadcast by each access point device of the at least two access point devices in this step.
The beacon frame includes DCI information and RSSI information.
Step S102, determining a target access point device from the at least two access point devices according to the device connection information and the signal strength information of each access point device of the at least two access point devices.
It should be understood that the terminal device determines the target access point device according to the DCI information and the RSSI information, but the RSSI information of the access point device does not change significantly, so that the DCI information broadcasted by the access point device has different values at different times or under different conditions, and the terminal device determines the target access point device according to the DCI information. For example, the terminal device receives a beacon frame broadcast by the first access point device, where the beacon frame includes DCI information carrying the number of connected terminal devices, and when the number of terminal devices is less than a set number, the first access point device satisfies an access condition, and the access point device is a target access point device; and under the condition that the number of the terminal devices is greater than or equal to the set number, the first access point device does not meet the access condition, and the access point device is not the target access point device.
In this embodiment, the content of the DCI information is defined as the number of terminal devices connected to the access point device, which is described in detail in the following embodiments.
And step S103, connecting the target access point equipment.
In the embodiment of the application, the terminal device receives the beacon frames of the at least two access point devices, and then confirms the target access point device of the at least two access point devices according to the device connection information and the signal strength information carried in the beacon frames, so that the number of the terminal devices connected by the access point devices is relatively balanced, the situation that one access point device is connected with too many terminal devices is avoided, and the average bandwidth and the uplink and downlink throughput rate of the terminal device are improved.
Optionally, the determining, according to the device connection information and the signal strength information of each of the at least two access point devices, a target access point device from the at least two access point devices includes:
respectively carrying out weighted calculation on the equipment connection information and the signal strength information of each access point equipment to determine the score of each access point equipment;
determining an access point device with the highest score of the at least two access point devices as the target access point device.
It should be understood that the score of the access point device is related to the RSSI of the access point device, but there is still a difference. For example, the terminal device includes a first access point device and a second access point device in a public WIFI environment, where the RSSI corresponding to the first access point device is 50, the RSSI corresponding to the second access point device is 40, but the score of the first access point device is 20, and the score of the second access point device is 30, and at this time, the terminal device is connected to the second access point device.
The score of each access point device represents the comprehensive situation of the device connection information and the signal strength information of each access point, and the higher the score is, the higher the speed of the terminal device and the access point device after connection is.
In this embodiment, when the terminal device receives beacon frames broadcast by at least two access point devices, the terminal device determines that one access point device is a target access point device from the at least two access point devices. In this embodiment, the device connection information and the signal strength information of each access point device are respectively weighted and calculated, the score of each access point device is determined, and the access point device with the highest score is determined as the target access point device, so that the average bandwidth and the uplink and downlink throughput rate of the terminal device are improved.
Optionally, the device connection information includes a connected number and a maximum connectable number;
the performing a weighted calculation on the device connection information and the signal strength information of each access point device, and determining a score of each access point device includes:
determining a ratio of the number of connected to the maximum number of connectable devices of each access point device as a connection rate of each access point device;
and performing weighted calculation on the signal strength information and the connection rate of each access point device according to the first weight corresponding to the signal strength information and the second weight corresponding to the device connection information, and determining the score of each access point device.
Illustratively, the terminal device performs weighted calculation on the device connection information and the signal strength information of each access point device, and the calculation process is represented by the following formula:
m＝i×RSSI+j×(1-r)×100
wherein m is used to characterize the score; the RSSI is used for representing the value of the RSSI; r is used for representing the connection rate of the access point equipment to the terminal equipment; i and j are used to characterize the weighting coefficients, i and j being constants.
For example, the terminal device scans three BSSIDs, where parsing the first BSSID confirms that the first RSSI is 70, r is 0.2; analyzing the second BSSID to confirm that the second RSSI is 80 and r is 0.7; the third BSSID was analyzed to confirm that the third RSSI was 70, and r was 0.1. In this example, assuming that i = j =0.5, it is confirmed that the score of each BSSID is:
m =75 for the first BSSID; m =50 for the second BSSID; m =80 for the third BSSID.
If the terminal equipment adopts the prior art when confirming the target access point equipment, the terminal equipment is connected with the access point equipment corresponding to the second BSSID; if the terminal device adopts the method provided by the embodiment of the application when confirming the target access point device, the terminal device is connected with the access point device corresponding to the third BSSID.
As can be seen from the above data, for the access point device corresponding to the second BSSID, the connected terminal device is much more than the terminal devices connected to the access point devices corresponding to the other two BSSIDs, and the average bandwidth and the uplink and downlink throughput rate are lower; for the access point device corresponding to the third BSSID, although the RSSI of the access point device is weaker than that of the access point device corresponding to the second BSSID, the number of the connected terminal devices is smaller, and the average bandwidth and the uplink and downlink throughput rate of the connected terminal devices are higher.
Compared with the prior art, the network access method provided by the embodiment of the application is more reasonable, and the average bandwidth and the uplink and downlink throughput rate of each terminal device can be effectively improved.
Optionally, the information element of the beacon frame includes a target number position, a field of the target number position is used to indicate the device connection information, and the target number position is an unused number position in the information element.
Referring to fig. 2, fig. 2 is a basic structure diagram of a beacon frame provided in the embodiment of the present application. The Media Access Control (MAC) headers of all beacon frames are the same, and the Information Element (IE) is an Element formed by the beacon frames, and the length of the Element is not constant, and usually includes an Element identification code (Element ID), a length of the Element ID, and a length of the Element ID, as shown in fig. 3. In the beacon frame, the element identification codes 43 to 49 are not used, and some of them may be used as device connection information.
For example, the element id 44 is set to the connected number and the maximum terminal access number, and the structure thereof is shown in table 1 below:
TABLE 1
Element identification code Length of Number of connected Maximum number of terminal accesses
44 2
In the above table, the device connection information only needs to store the information of two basic fields, so the length padding is 2; for the access point equipment, the self system supports to acquire the number of the connected terminal equipment, and the number generally does not exceed 255, so one byte is adopted for storage; for the access point device, its own system supports obtaining the maximum terminal access number, and the number generally does not exceed 255, so one byte is used for storage.
It should be understood that the access point device broadcasts the beacon frame carrying the element identification code, the terminal device analyzes and confirms the connected number and the maximum terminal access number of the access point device after receiving the beacon frame, and the terminal device performs weighting calculation to select an access point device with better average bandwidth and RSSI, thereby improving the internet experience of the user.
Referring to fig. 3, fig. 3 is a flowchart of a network access method provided in an embodiment of the present application, which is executed by an access point device, and as shown in fig. 3, the method includes the following steps:
step S301, determining the device connection information of the access point device according to the number information of the terminal devices currently connected to the access point device, wherein the device connection information is used for representing the number of the terminal devices connected to the access point device.
The access point device updates the device connection information when the number of the terminal devices connected to the access point device changes.
The access point device may be configured to determine the connection number of the terminal device once in a set period, update the device connection information when the number changes, and directly enter the next period without updating when the number does not change.
Step S302, sending a beacon frame, wherein the beacon frame includes the device connection information, and the beacon frame is used for enabling the terminal device to determine a target access point device to be connected.
The device connection information carried by the beacon frame is the latest device connection information.
It should be understood that the beacon frame includes device connection information and also includes RSSI information for each access point device. And after receiving the beacon frames of the multiple devices, the terminal device confirms the target access point device and connects the target access point device according to the device connection information and the RSSI information.
In the embodiment of the application, the access point device confirms the device connection information according to the number of the terminal devices, continuously updates the device connection information, and broadcasts the beacon frame carrying the device connection information, so that the terminal devices can select the access point device according to the device connection information and the RSSI information, the situation that one access point device is connected with too many terminal devices is avoided, and the effects of improving the average bandwidth and the uplink and downlink throughput rate of the terminal devices are achieved.
Optionally, the device connection information includes a connected number and a maximum connectable number, or the device connection information includes a remaining connectable number.
The connected number and the maximum connectable number may indicate the connection confirmation rate of the terminal device, and are not described herein again.
The device connection information includes the remaining connectable number, and the terminal device may confirm the score of the access point device through the remaining connectable number and the RSSI strength.
Illustratively, the score of the access point device is determined by the following equation:
n＝f 1 ×RSSI+f 2 ×k
wherein n is used to characterize the access point score; the RSSI is used for representing the RSSI information of the access point equipment, and the k is used for representing the residual connectable number; f. of 1 And f 2 For characterizing the coefficients, f 1 And f 2 Is a constant.
For example, the remaining connectable number of the first access point device is 20, the rssi strength is 50; the remaining number of connectable second access point devices is 80, the rssi strength is 45, f 1 ＝1，f 2 =0.5. In this case, the first access point device is given a score of 60, the second access point device is given a score of 85, and the terminal device connects to the second access point device.
Optionally, after determining the device connection information and before sending the beacon frame, the method further includes:
adding a field for indicating the device connection information at a target number position in an information element of the beacon frame, wherein the target number position is an unused number position in the information element.
It should be understood that a field for indicating device connection information is added to an unused label position of a beacon frame broadcast by the access point device, the terminal device analyzes and confirms the connected number and the maximum terminal access number of the access point device after receiving the beacon frame, and then performs weighted calculation on the terminal device, so as to select an access point device with better average bandwidth and RSSI, thereby improving the internet experience of a user.
