Detailed Description

At present, the implementation manner of testing, analyzing and optimizing the service quality of the WIFI network mainly adopts: after the terminal accesses the WIFI network, collecting test data, and reporting the collected test data to a server; the server analyzes and processes the collected test data, in other words, the terminal only completes simple test, data collection and reporting work, and the value of the terminal to the WIFI network optimization work is seriously underestimated.

Based on this, in various embodiments of the invention: the method comprises the steps that a terminal obtains transmission parameters of mutual information in the WIFI network access process; and the terminal analyzes the WIFI network access capability according to the acquired transmission parameters of the interactive information.

As shown in fig. 1, the method for detecting WIFI network access capability provided by the embodiment of the present invention includes the following steps:

step 101: the method comprises the steps that a terminal obtains transmission parameters of mutual information in the WIFI network access process;

here, acquiring and analyzing an interactive message in the self WIFI network access process;

Fig. 2 is a schematic diagram of an information interaction process in a WIFI network access process according to an embodiment of the present invention; as shown in fig. 2, in practical application, an information interaction process in a general normal WIFI network access process includes:

step 201: dynamic Host Configuration Protocol (DHCP) Discovery (DISCOVER) (01);

specifically, the terminal firstly broadcasts a DHCP DISCOVER message, aiming at enabling a DHCP Server (Server) to receive an access request;

step 202: DHCP response (OFFER) (02);

specifically, after receiving the DHCP DISCOVER message, the DHCP Server responds to the terminal with a DHCP OFFER message.

Wherein, the DHCP OFFER message carries the IP address that the DHCP Server can provide for the terminal to use.

Step 203: DHCP REQUEST (03);

specifically, after receiving the DHCP OFFER message, the terminal broadcasts a DHCP REQUEST (REQUEST) message.

Wherein, the DHCP REQUEST message carries DHCP SERVER IP address and the IP address desired by the user.

Step 204: a DHCP Acknowledgement (ACK) (05);

specifically, after receiving the DHCP REQUEST message, the DHCP Server determines whether the IP address of the DHCP Server in the "option" field of the DHCP REQUEST message is the same as its own IP address, and when the IP address of the DHCP Server in the "option" field of the DHCP REQUEST message is the same as its own IP address, the DHCP Server responds to the terminal with a DHCP ACK message and adds an IP address use lease option in the "option" field of the DHCP ACK message.

Here, after the DHCP Server refuses to respond to the received DHCP REQUEST message, a DHCP refusing (NACK) (06) message is replied to the terminal; after receiving the DHCP NACK message, the terminal generally restarts to perform step 201.

Step 205: address Resolution Protocol (ARP) Request;

specifically, after receiving the DHCP ACK message, the terminal sends an ARP Request message to the AP, where the ARP Request message is used to obtain a Media Access Control (MAC) address of the AP.

Step 206: ARP reply (Replay);

specifically, after receiving the ARP Request message, the AP replies an ARP reply message to the terminal.

Wherein, the ARP Replay message carries the IP address and the MAC address of the AP.

The purpose of executing step 205 and step 206 is: the terminal acquires the MAC address of the target host and establishes connection with the hot spot and the AP; the terminal detects whether the acquired IP address has conflict or not and whether the IP address is used by other terminals or not.

According to the above description, the WIFI network access process can be divided from the terminal side into: a DHCP discovery subprocess, an IP address acquisition subprocess and a conflict detection and MAC address acquisition subprocess; the DHCP discovery subprocess includes steps 201 and 202; the IP address acquisition subprocess includes: step 203 and step 204; the collision detection and MAC address acquisition sub-process comprises: step 205 and step 206.

Based on this, the transmission parameters of the interactive message include: the method comprises the steps of sending the DHCP DISCOVER message within first preset time, feeding back delay time of the DHCP OFFER message, time delay between sending the DHCP REQUEST message and receiving the DHCP ACK message, sending times of the ARP REQUEST message within second preset time and time delay between sending the ARP REQUEST message and receiving the ARP Replay message.

The first preset time and the second preset time are set according to a protocol rule followed by the WIFI network, for example: setting the first preset time to 10s, setting the second preset time to 5s and the like; when the number of sending ARPRequest messages is more than two, the time delay between sending the ARP Request message and receiving the arprepeat message refers to: the time interval between the first time of sending the ARP Request message and the time of receiving the ARP Replay message.

In practical application, the test software for implementing the method of the embodiment of the invention needs to be installed to the terminal, and the ROOT authority of the operating system of the terminal is obtained, so that the transmission parameters of the interactive messages in the WIFI network access process of the terminal can be obtained; the obtaining of the ROOT authority of the operating system of the terminal includes: becoming the administrator of the operating system of the terminal; the specific process of obtaining the ROOT authority of the operating system of the terminal is a conventional technical means for those skilled in the art, and is not described in detail.

The terminal can be an intelligent terminal with an Android system, such as: can be an intelligent terminal with an android2.0 system.

The specific processing procedure of obtaining the interactive message in the self-WIFI network access process and analyzing is a conventional technical means of those skilled in the art, and is not described in detail.

Step 102: and the terminal analyzes the WIFI network access capability according to the acquired transmission parameters of the interactive information.

Specifically, the terminal compares the acquired transmission parameters of the interactive information with the set transmission parameters of the WIFI network standard respectively to obtain a comparison result;

Here, when the transmission parameters of the interactive packet include: when the sending times of the DHCP DISCOVER message in the first preset time, the feedback delay time of the DHCP OFFER message, the time delay between sending the DHCP REQUEST message and receiving the DHCP ACK message, the sending times of the ARP REQUEST message in the second preset time, and the time delay between sending the ARP REQUEST message and receiving the ARP reply message, correspondingly, the set WIFI network standard transmission parameters also include: the method comprises the steps of sending times of DHCPDISCOVER messages in first preset time, feedback delay time of DHCP OFFER messages, time delay between sending of DHCPREQUEST messages and receiving of DHCP ACK messages, sending times of ARPRequest messages in second preset time, and time delay between sending of ARP Request messages and receiving of ARP Replay messages.

The WIFI network standard transmission parameters are set according to a protocol followed by the WIFI network, in other words, the WIFI network standard transmission parameters are set according to the WIFI network transmission parameters specified by the protocol followed by the WIFI network; for example, assuming that a protocol followed by the WIFI network specifies that the number of sent DHCP DISCOVER messages is at most 5 within a first preset time, the number of sent DHCP DISCOVER messages in the set WIFI network standard transmission parameters is 5, and so on.

When comparing, comparing one item in the transmission parameters of the interaction information with the same item in the set WIFI network standard transmission parameters; for example, the sending times of the DHCP DISCOVER messages within the first preset time in the transmission parameters of the interaction information are compared with the sending times of the DHCP DISCOVER messages within the first preset time in the set WIFI network standard transmission parameters, the feedback delay time of the DHCP OFFER messages in the transmission parameters of the interaction information is compared with the feedback delay time of the DHCP OFFER messages in the set WIFI network standard transmission parameters, and the like.

Determining, according to the comparison result, a specific implementation of a factor affecting the WIFI network access performance may be multiple, for example, when the number of sending times of the DHCPDISCOVER packet in the first preset time in the transmission parameters of the interaction packet is greater than the number of sending times of the DHCP DISCOVER packet in the first preset time in the set WIFI network standard transmission parameters, in other words, when the DHCP OFFER packet is not received in the set time, the DHCP Server is considered to have no response, and determining the factor affecting the WIFI network access performance may include: the coverage of the WIFI network in the environment where the terminal is located is weak, so that normal information interaction cannot be carried out between the DHCP Server and the terminal; and/or, the DHCP Server of the target WIFI network is damaged or has hidden faults, so that the DHCP Server can not work normally; and/or the WIFI network access equipment connected with the terminal fails, so that information between the terminal and the DHCP Server cannot reach the DHCPServer and the like;

when the feedback delay time of the DHCP OFFER message in the transmission parameters of the interaction message is greater than the feedback delay time of the DHCP OFFER message in the set WIFI network standard transmission parameters, determining the factor affecting the WIFI network access performance may include: the wireless environment interference is large, so that normal information interaction cannot be carried out between the DHCPServer and the terminal, and the information message is damaged due to a large error rate; and/or the coverage of the WIFI network in the environment where the terminal is located is weak, so that normal information interaction cannot be carried out between the DHCP Server and the terminal; and/or when the DHCP Server is busy, the DHCP Server cannot send the DHCP OFFER message to the feedback terminal; and/or, the DHCP Server of the target WIFI network is damaged or has hidden faults, so that the DHCP Server cannot normally work, requests are lost and the like;

when the time delay from sending the DHCP REQUEST message to receiving the DHCPACK message in the transmission parameters of the interaction message is greater than the time delay from sending the DHCPREQUEST message to receiving the DHCP ACK message in the set WIFI network standard transmission parameters, or the terminal does not receive the DHCP ACK message within a set time, determining that the factor affecting the WIFI network access performance may include: the interference of wireless environment is large, so that the DHCP Server and the terminal can not carry out normal information interaction, and the information message is damaged due to large error rate; and/or the coverage of the WIFI network in the environment where the terminal is located is weak, so that normal information interaction cannot be performed between the DHCP Server and the terminal; when receiving a DHCP NACK message fed back by a DHCP Server of the target WIFI network, determining factors that affect the WIFI network access performance may include: the DHCP Server of the target WIFI network is damaged or has hidden faults, so that the DHCP Server cannot work normally;

when the number of times of sending the ARP Request message within the second preset time in the transmission parameters of the interactive message is greater than the number of times of sending the ARP Request message within the preset time in the set WIFI network standard transmission parameters, determining that the factor affecting the WIFI network access performance may include: the WIFI network access equipment (namely AP) connected with the terminal is damaged or has hidden faults, and cannot work normally;

when the time delay between sending the ARP Request message and receiving the ARP reply message in the transmission parameters of the interactive message is greater than the time delay between sending the ARP Request message and receiving the ARP reply message in the set WIFI network standard transmission parameters, determining that the factors affecting the access performance of the WIFI network may include: the wireless environment has large interference or weak coverage; and/or the WIFI network access equipment (namely AP) connected with the terminal is damaged or has hidden faults, and the WIFI network access equipment cannot work normally.

The method may further comprise: the terminal acquires data of a wireless environment in which the terminal is located;

correspondingly, when analyzing the WIFI network access capability, the method may further include:

Wherein the data of the wireless environment may include: information of the wireless environment; here, the information of the wireless environment may include: the method comprises the steps of obtaining the signal strength of the WIFI network received by the terminal, the signal quality and the coverage of the WIFI network received by the terminal, the co-adjacent frequency interference of the peripheral WIFI network, the internal and external interference and the like.

Here, the signal quality and the coverage of the WIFI network received by the terminal may be determined by the following method: the terminal continuously acquires the intensity of the wireless signal of the WIFI network received by the terminal within a set time, and calculates an average value; judging the signal quality and the coverage range of the WIFI network received by the terminal according to the calculated average value; for example, generally, if the obtained average value is greater than or equal to-80 dBM, the coverage range is normal; if the obtained average value is less than-90 dBM, the coverage range is weak, the hotspot access time delay of the terminal is long, the success rate is low, and the access maintenance stability is poor; if the obtained average value is larger than or equal to-90 dBM and smaller than-80 dBM, the coverage range is normal, but the signal quality is unstable, for example, the bit error rate is higher, and the service quality is influenced.

The same-adjacent-channel interference of the peripheral WIFI network can be determined by adopting the following method: superposing the calculated average value of the wireless signal intensity on the wireless signal intensity power value of the peripheral same-frequency WIFI network to serve as the same-frequency interference of the peripheral WIFI network; superposing the calculated average value of the wireless signal strength on the wireless signal strength power value of the peripheral adjacent-frequency WIFI network to serve as adjacent-frequency interference of the peripheral WIFI network; in practical application, the adjacent frequency means: and the WIFI network has a WIFI network channel interval of 1 with the WIFI network where the terminal is located.

The internal interference present is: network signals of the same Service Set IDentifier (SSID) and/or the same frequency point and/or different Basic Service Set Identifiers (BSSID) as the target WIFI network; accordingly, the external interference present refers to: and outputting other network signals except the network signals with the same SSID (service set identifier), the same frequency point and/or different BSSIDs (basic service set identifiers) with the target WIFI network.

The obtained transmission parameters of the interaction information and the obtained data of the wireless environment are used for analyzing the WIFI network access capability, and the method specifically comprises the following steps:

Here, the data of the WIFI network standard wireless environment is also set according to the protocol followed by the WIFI network, in other words, the data of the WIFI network standard wireless environment is set according to the data of the WIFI network wireless environment specified by the protocol followed by the WIFI network; the specific setting process is the same as the process of setting the transmission parameters of the WIFI network standard, and is not illustrated here.

In actual application, comparing the acquired transmission parameters of the interactive information and the acquired data of the wireless environment with the set transmission parameters of the WIFI network standard and the data of the wireless environment to obtain a comparison result; a specific processing procedure for determining the factors affecting the access performance of the WIFI network according to the comparison result, as shown in fig. 3, may include the following steps:

step 301: the terminal acquires transmission parameters of the interactive message and data of a wireless environment;

step 302: the terminal judges whether the carrier-to-interference ratio of the wireless environment is greater than or equal to a first threshold value; if yes, executing step 303, otherwise, executing step 304;

calculating a carrier-to-interference ratio of the wireless environment by using the signal intensity of the WIFI network received by the terminal and the co-adjacent frequency interference of the peripheral WIFI network, specifically, multiplying the co-frequency interference value of the WIFI network peripheral to the WIFI network received by the terminal by 0.7 to obtain a first value; multiplying the adjacent channel interference value of the WIFI network surrounding the WIFI network received by the terminal by 0.3 to obtain a second value; adding the first value and the second value to obtain a third value; dividing the signal intensity of the WIFI network received by the terminal by a third value to obtain the carrier-to-interference ratio of the wireless environment; the carrier-to-interference ratio calculation for a wireless environment is expressed by a formula, which includes:

the first threshold is set according to the relevant protocol regulations followed by the WIFI network, for example, the first threshold is set to 15 dB.

When the carrier-to-interference ratio of the wireless environment is greater than or equal to a first threshold, the wireless environment is good, and the interference of peripheral wireless signals is small; when the carrier-to-interference ratio of the wireless environment is smaller than the first threshold, it is determined that the interference is large, and step 304 needs to be executed to further determine whether the interference of the peripheral wireless signals is large and affect the access quality of the WIFI network.

Step 303: the terminal analyzes a DHCP interaction process and an ARP interaction process by combining the acquired transmission parameters of the interaction message and the related data of the wireless environment;

here, the DHCP interaction process includes: steps 201-204 in the information interaction process shown in FIG. 2; the ARP interactive process comprises the following steps: steps 205-206 in the information interaction process shown in FIG. 2.

The specific implementation of the step comprises the following steps:

step 303 a: the terminal determines that the terminal does not receive the DHCP OFFER message within the first preset time, judges whether the signal strength of the WIFI network received by the terminal is good, and if the signal strength is good, the terminal indicates that the DHCP Server of the target WIFI network has a hidden fault or the WIFI network access equipment connected with the terminal has a fault; if the signal intensity is poor, the coverage of the WIFI network in the environment where the terminal is located is weak;

here, it is determined that the DHCP OFFER message is not received within the first preset time, in other words, it is determined that the number of times of sending the DHCP DISCOVER message within the first preset time in the transmission parameters of the interaction message is greater than the number of times of sending the DHCP DISCOVER message within the first preset time in the set WIFI network standard transmission parameters.

The terminal judges whether the signal intensity of the WIFI network received by the terminal is good or not, and specifically comprises the following steps:

the terminal judges whether the signal intensity of the WIFI network received by the terminal is good or not according to the signal quality and the coverage range of the WIFI network received by the terminal;

the received signal quality and coverage range of the WIFI network may be determined by the following method: the terminal continuously acquires the intensity of the wireless signal of the WIFI network received by the terminal within a set time, and calculates an average value; judging the signal quality and the coverage range of the WIFI network received by the terminal according to the calculated average value; generally, if the obtained average value is more than or equal to-80 dBM, the coverage range is normal; the signal strength of the WIFI network received by the terminal is good, if the obtained average value is smaller than-90 dBM, the coverage range is weak, the hotspot access time delay of the terminal is long, the success rate is low, and the access keeping stability is poor; if the obtained average value is larger than or equal to-90 dBM and smaller than-80 dBM, the coverage range is normal, but the signal quality is unstable, for example, the bit error rate is higher, and the service quality is influenced.

Step 303 b: the terminal determines that the feedback delay time of the DHCP OFFER message is greater than the feedback delay time of the DHCP OFFER message in the set WIFI network standard transmission parameters, judges whether the signal intensity of the WIFI network received by the terminal is good, and if the signal intensity is good, the terminal indicates that the DHCP Server of the target WIFI network has a hidden fault or is busy; if the signal intensity is poor, the coverage of the WIFI network in the environment where the terminal is located is weak;

here, the terminal determines whether the signal strength of the WIFI network received by the terminal is good, specifically:

the received signal quality and coverage range of the WIFI network may be determined by the following method: the terminal continuously acquires the intensity of the wireless signal of the WIFI network received by the terminal within a set time, and calculates an average value; judging the signal quality and the coverage range of the WIFI network received by the terminal according to the calculated average value; generally, if the obtained average value is larger than or equal to-80 dBM, the coverage range is normal, and the signal intensity of the WIFI network received by the terminal is good; if the obtained average value is less than-90 dBM, the coverage range is weak, the hotspot access time delay of the terminal is long, the success rate is low, and the access maintenance stability is poor; if the obtained average value is larger than or equal to-90 dBM and smaller than-80 dBM, the coverage range is normal, but the signal quality is unstable, for example, the bit error rate is higher, and the service quality is influenced.

Step 303 c: the terminal determines to receive a DHCPNACK message fed back by a DHCP Server of a target WIFI network, and indicates that the DHCP Server of the target WIFI network is damaged or has hidden faults;

step 303 d: the terminal determines that the sending times of ARP Request messages in second preset time are greater than the sending times of the ARP Request messages in second preset time in the set WIFI network standard transmission parameters, or the time delay from sending the ARP Request messages to receiving the ARP Replay messages is greater than the time delay from sending the ARP Request messages to receiving the ARP Replay messages in the set WIFI network standard transmission parameters, judges whether the signal strength of the WIFI network received by the terminal is good or not, and if the signal strength is good, indicates that WIFI network access equipment (namely AP) connected with the terminal is damaged or has hidden faults; and if the signal strength is poor, the coverage of the WIFI network in the environment where the terminal is located is weak.

Here, the number of times of sending the ARP Request packet within the second preset time is greater than the number of times of sending the ARP Request packet within the second preset time in the set WIFI network standard transmission parameter, and means: and the ARP Replay message is not received within a second preset time.

The time delay between sending the ARP Request message and receiving the ARP reply message is greater than the time delay between sending the ARP Request message and receiving the ARP reply message in the set WIFI network standard transmission parameter, in other words, the time delay between receiving the ARP reply message is too large.

In practical application, the steps 303a, 303b, 303c and 303d are executed without any sequence.

Step 304: the terminal determines whether a problem exists in the DHCP process and the ARP interactive process.

Here, the specific implementation of this step includes the following steps:

step 304 a: the terminal judges whether the feedback delay time of the DHCP OFFER message is larger than the feedback delay time of the DHCP OFFER message in the set WIFI network standard transmission parameters, if so, the step 304d is executed;

step 304 b: the terminal judges whether the time delay from sending the DHCP REQUEST message to receiving the DHCP ACK message is larger than the time delay from sending the DHCPREQUEST message to receiving the DHCP ACK message in the set WIFI network standard transmission parameters, if so, the step 304d is executed;

here, it is determined whether the time delay between sending the DHCP REQUEST message and receiving the DHCP ACK message is greater than the time delay between sending the DHCP REQUEST message and receiving the DHCP ACK message in the set WIFI network standard transmission parameters, in other words, it is determined whether the interaction time delay between the DHCP REQUEST message and the DHCP ACK message is too large, that is: and judging whether the time delay of receiving the DHCP ACK message is overlarge.

Step 304 c: the terminal judges whether the time delay between the ARP Request message sending and the ARP Replay message receiving is larger than the time delay between the ARP Request message sending and the ARP Replay message receiving in the set WIFI network standard transmission parameters, if so, the step 304d is executed;

here, it is determined that a time delay between sending the ARP Request message and receiving the ARP reply message is greater than a time delay between sending the ARP Request message and receiving the ARP reply message in the set WIFI network standard transmission parameter, in other words, it is determined whether the received ARP reply message is too large.

In practice, the steps 304a, 304b, and 304c are executed without any sequence.

Step 304 d: the terminal determines that the peripheral wireless signals have serious interference and influences the access quality of the WIFI network.
