It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
At present, when a terminal performs a VoWiFi call, normal voice data is a data packet every 20 milliseconds (ms), but under the condition of large network delay, there will be some delays (delays) in an operator network and a routing relay, which may cause a packet received by a receiving end to be discontinuous, and if the delay occurs in continuous 3 frames or more of data, the receiving end will be stuck obviously, which seriously affects the call quality. Therefore, the service layer adds a receiving buffer (buffer) at the receiving end, and performs speech decoding when the received data meets the preset size. The method avoids the jamming problem caused by the discontinuous received data to a certain extent. However, the communication quality cannot be guaranteed by aiming at the problems of network environment interference and the like in the communication process.
In view of the foregoing problems, an embodiment of the present application provides a method for adjusting a network parameter, which is applied to a terminal. The following detailed description is made with reference to the accompanying drawings.
First, please refer to the schematic structural diagram of the network parameter adjustment system 100 shown in fig. 1, which includes a terminal 110, a Wireless Fidelity (Wi-Fi) 120, and a Wireless access point (Wireless AP) 130.
The Voice over Wi-Fi (Voice over Wi-Fi) is a special communication mode for a terminal to communicate by using a Wireless Fidelity (Wi-Fi) network, and effectively solves the problem that the communication quality of the terminal is influenced when the signal coverage of an area is too poor (such as indoors or in an interfered area). The terminal is connected with the Wi-Fi and sends data to the AP through the Wi-Fi. When the terminal performs the VoWiFi service, the first transmission power of the terminal, the load of the wireless access point, the signal intensity of the wireless access point, and other network environment parameters all affect the communication effect of the terminal VoWiFi service.
The terminal 110 includes, but is not limited to, a device with a communication function, a smart phone, a tablet computer, a notebook computer, a desktop computer, a portable digital player, a smart band, a smart watch, and the like.
The Wi-Fi120 is a network transmission standard, which belongs to a short-distance wireless technology, like a bluetooth technology. Wi-Fi is a wireless networking technology. The wireless network transmission technology is to convert wired network signals into wireless signals, and use wireless routers for receiving related terminals and the like supporting the technology. If the terminal has the Wi-Fi function, the network access can be realized without the network of an operator when the terminal has the Wi-Fi wireless signal.
The wireless AP130, a pure wireless AP, may be a wireless switch, and only provides the function of transmitting wireless signals. The working principle is that network signals are transmitted through a twisted pair, and the electric signals are converted into radio signals to be transmitted through the compiling of AP products, so that the coverage of a wireless network is formed. A terminal connected to the wireless AP may forward data out through the AP.
The technical solution of the embodiment of the present application may be implemented based on the communication system with the architecture illustrated in fig. 1 by way of example or a modified architecture thereof.
Referring to fig. 2, fig. 2 is a schematic flowchart of a method for adjusting network parameters according to an embodiment of the present application, where the method may include, but is not limited to, the following steps:
201. obtaining network environment parameters, wherein the network environment parameters comprise one or more of the following: signal strength of the terminal, response message of the wireless access point, signal strength of the wireless access point, load of the wireless access point.
Specifically, it can be understood that the terminal detects the current network environment parameter before sending data. The network environment parameters include one or more of: signal strength of the terminal, response message of the wireless access point, signal strength of the wireless access point, load of the wireless access point. The signal strength of the terminal is the signal strength when the terminal sends data, and the strength of the signal strength affects the transmission effect of the terminal data. dBm is a unit of wireless signal strength. The signal strength is generally between-90 dBm and 0 dBm. In general, the signal intensity between-50 and 0 is good, and the use perception is good. The signal strength between-70 and-50 is good, the use perception is slightly poor, but no obvious influence is caused on the experience. Signals below-70 are not so good and are not well perceived in use.
The signal strength of a wireless access point is the strength of the signal strength within the range covered by the network of the wireless access point. As with the signal strength of the terminal, it is in dBm. The strength of the data transmission can affect the data transmission effect of the terminal, and the user is likely to be in the moving state in the coverage range of the wireless network. However, since signal coverage of a single AP (wireless access point) device is limited, the signal strength of the wireless access point may also change dynamically during the movement of the user and the terminal corresponding to the user.
In addition, the response message of the wireless access point, that is, the response of the wireless AP to the inquiry information of whether to transmit the indication information by the terminal, can determine whether to transmit the indication information to the wireless AP by using the response message.
In addition, the load of the wireless access point is the number of other hidden nodes (terminals) and the number of exposed nodes (terminals) within the interference range (IF-range) of the wireless AP. These hidden or exposed nodes send frames to the wireless AP, which will interfere with terminal reception and result in frame loss. When the terminal sends data to the wireless AP, it is likely that data of the terminal is lost because other nodes are also sending data to the wireless AP, so that the packet loss rate is increased, and the communication effect is affected.
Optionally, before the obtaining of the network environment parameter, the method further includes: and if the data to be sent is the first data, executing the step of acquiring the network environment parameters.
Specifically, it can be understood that when the terminal uses Wi-Fi to perform data transmission, the terminal may first detect the type of the transmission data, so as to determine whether the data to be transmitted is the first data. The first data may be data preset by the terminal when the terminal performs the VoWiFi service, such as voice data. Further, after determining that the data to be sent is the first data, the terminal executes the step of acquiring the network environment parameters.
In addition, the terminal may perform the step of acquiring the network environment parameter when receiving data transmitted from another terminal when performing the VoWiFi service using the Wi-Fi, or when preparing the VoWiFi service.
202. If the network environment parameters do not meet the corresponding preset conditions, network configuration parameters are adjusted, wherein the network configuration parameters comprise one or more of the following: the transmission power of the terminal, the indication information and the switching parameter of the terminal.
Specifically, the terminal detects that the network environment parameter does not satisfy a corresponding preset condition, where the corresponding preset condition is a condition set for different parameters specifically corresponding to the network environment parameter. Such as which level of 1-5 the terminal's transmit power is; or what the load of the wireless access point is; or, when the signal strength of the wireless access point is at that value. For example, please refer to table 1, where table 1 is a data table of different power levels corresponding to different power values or value ranges. The lowest level among the power levels is N, the power value is 0dBm, and N can be 15, 20, or 10, etc. The highest of the power levels is 1, and the power value can be 30 dBm.
Power class Power value or value range
1 30dBm
2 20dBm-30dBm
… …
N 0dBm
TABLE 1
Under the condition that the terminal detects that the network environment parameters do not meet the corresponding preset conditions, the terminal adjusts network configuration parameters, wherein the network configuration parameters comprise one or more of the following parameters: the transmission power of the terminal, the indication information and the switching parameter of the terminal. That is, the terminal correspondingly adjusts the network configuration parameters according to the network environment parameters of the terminal.
It is to be understood that the network environment parameters and the network configuration parameters may correspond. Such as the signal strength of the terminal corresponding to the transmit power of the terminal. When the signal strength of the terminal is weak, the success rate of data transmission can be improved by adjusting the transmission power of the terminal.
The first data is data when the terminal performs the VoWiFi service, or data to be sent when the terminal is going to perform the VoWiFi service; the second data is data when the terminal performs other services except the VoWiFi service.
It can be seen that, in the embodiment of the present application, the terminal determines whether the network environment parameter meets the corresponding preset condition according to the acquired network environment parameter. And when not satisfied, the terminal adjusts network configuration parameters, the network configuration parameters including one or more of: the transmission power of the terminal, the indication information and the switching parameter of the terminal. The terminal adjusts the corresponding network configuration parameters by detecting one or more parameters of the network environment. Aiming at different problems of the network environment, the transmission power of the terminal can be adjusted, or the indication information and the switching parameter of the terminal can be adjusted to optimize the network environment of the terminal communication. The success rate of data transmission is improved, and the packet loss rate is reduced.
In a possible example, the adjusting the network configuration parameter if the network environment parameter does not satisfy the corresponding preset condition includes: if the threshold value for adjusting the transmission power is not equal to the first transmission power threshold value, detecting whether the signal intensity of the terminal is lower than the signal intensity threshold value of the terminal; if the signal intensity of the terminal is lower than the signal intensity threshold value of the terminal, adjusting the sending power of the data; and the first transmission power threshold is the transmission power threshold when the terminal transmits the second type of data.
Specifically, if the network environment parameter does not satisfy the corresponding preset condition, the terminal adjusts the network configuration parameter. The transmit power of the terminal may be adjusted, and the specific adjustment process is as follows: if the threshold for adjusting the transmission power is equal to the first transmission power threshold, detecting whether the signal strength of the terminal is lower than the signal strength threshold of the terminal. As described above, the transmission power of the first terminal is the power when the data to be transmitted is not transmitted yet and the power when the terminal transmits other data currently.
The first transmission power threshold is a transmission power threshold when the terminal transmits the second type of data. That is, the threshold (TH-Power) for whether or not the transmission Power is increased when the terminal transmits the second data, which is set in advance, may be written as value 4. It can also be understood that the terminal detects that TH-Power is equal to value4, then an adjustment of the transmission Power is needed; otherwise, if the first transmission power is equal to the second transmission power threshold, the transmission power does not need to be adjusted. The second transmission power threshold is a threshold set in advance as to whether or not the transmission power is increased when the terminal transmits the first data, and may be recorded as value 1. It can also be understood that if the terminal detects that TH-Power is equal to value1, no adjustment of the transmit Power is required.
Further, after the terminal detects whether the threshold (TH-Power) for adjusting the transmission Power is equal to the first transmission Power threshold, it detects whether the signal strength of the terminal is lower than the threshold (TH _ low _ rssi) for adjusting the transmission Power. The signal strength threshold of the terminal may be a lowest value of signal strength of transmitting the first data, which is preset by the terminal; or the terminal performs the lowest value of the signal strength when receiving the VoWiFi service data.
Optionally, if the threshold of whether to adjust the transmission power is equal to the second transmission power threshold, the first transmission power of the terminal is not adjusted.
Further, if the signal strength of the terminal is lower than the signal strength threshold of the terminal, the transmission power of the data is adjusted. The signal strength threshold of the terminal may also be understood as a threshold that triggers the selection of a boost in transmit power.
Optionally, the adjusting the transmission power of the data includes: determining a target transmission power level of the terminal; and adjusting the transmission power of the data according to the target transmission level.
Specifically, the terminal determines a target transmission power level of the terminal, and adjusts the transmission power of the data according to the target transmission level. The target transmit power level of the terminal may be determined by first calculating a power boosting level, and then setting the power boosting level as the target transmit power level based on the current power level. The level of computational power boost may be determined according to the following equation:
N＝(TH_low_rssi-rssi)/5+1
where N is the level of power boosting, TH _ low _ rssi is the Signal Strength threshold of the terminal, which can also be understood as the threshold for triggering selection of boosting of the transmission power, and rssi is the current Received Signal Strength Indication (rssi) of the terminal.
It can be seen that, in the embodiment of the present application, when the first transmission power obtained by the terminal is equal to the first transmission power threshold, that is, the first transmission power of the terminal in the network environment parameter does not satisfy the preset condition, it is detected whether the signal intensity of the terminal is lower than the signal intensity threshold of the terminal; and if the signal strength of the terminal is lower than the signal strength threshold value of the terminal, adjusting the sending power of the data. The sending rate of the terminal is improved, the sending power of the terminal is guaranteed to be matched with the preset conditions, the packet sending retransmission rate is reduced, and the communication effect is optimized.
In a possible example, the adjusting the network configuration parameter if the network environment parameter does not satisfy the corresponding preset condition includes: acquiring a response message of the wireless access point, wherein the response message is used for indicating whether the terminal sends the indication information to the wireless access point; under the condition that the indication information is determined to be sent to the wireless access point according to the response message, if the threshold value for sending the indication information is detected to be equal to the threshold value of the first indication information, the first indication information is sent; or if the threshold value for detecting the sending indication information is equal to the threshold value of the second indication information, sending the second indication information.
Specifically, if the network environment parameter does not satisfy the corresponding preset condition, the terminal adjusts the network configuration parameter, which may be adjustment indication information. The specific adjustment process is as follows: and acquiring a response message of the wireless access point, wherein the response message is used for indicating whether the terminal sends the indication information to the wireless access point. Whether the terminal sends the indication information to the wireless access point may be understood as whether the terminal enables RTS or CTS-to-self protection policy.
Further, in the case of determining to transmit the indication information to the wireless access point according to the response message, if it is detected that the threshold value of the transmission indication information is equal to the first indication information threshold value, the first indication information is transmitted. The first indication information is sent, i.e. a CTS-to-self protection strategy is enabled. Or if the threshold value of the sending indication information is detected to be equal to the threshold value of the second indication information, the second indication information is sent. And sending second indication information, namely RTS protection strategy.
When the first indication information threshold is data transmitted by the terminal or data to be transmitted is first data, a threshold (TH _ R) enabling a CTS-to-self protection policy may be recorded as value3, that is, TH _ R is value 3. The data sent by the terminal is the first data, that is, the data sent by the terminal when performing the VoWiFi service, or the data to be sent when the terminal is going to perform the VoWiFi service. When the second indication information threshold is data transmitted by the terminal or data to be transmitted is second data, the threshold (TH _ R) enabling the RTS protection policy may be marked as value6, that is, TH _ R is value 6. The second data is data when the terminal performs other services except the VoWiFi service.
It can be seen that, when the terminal acquires the response message of the wireless access point and determines to send the indication information to the wireless access point according to the response message, the threshold for detecting the sending indication information is equal to the first indication information threshold or equal to the second indication information threshold. Indeed data transmission enabled protection strategies. In this way, the degree of preparation of whether RTS or CTS protection is enabled is promoted, and a specific enabled policy is further determined according to the indication information threshold. The packet loss rate of the terminal data transmission is reduced, and the success rate of data transmission is improved.
In a possible example, the adjusting the network configuration parameter if the network environment parameter does not satisfy the corresponding preset condition includes: detecting the signal strength of at least one or more wireless access points if the signal strength of the wireless access points is less than a first handover threshold; selecting a wireless access point with the largest signal strength from the at least one or more wireless access points as a target wireless access point; and switching to the target wireless access point.
Specifically, if the network environment parameter does not satisfy the corresponding preset condition, the terminal adjusts the network configuration parameter, which may be a handover parameter of the terminal. The specific adjustment process is as follows: and if the signal strength of the wireless access point is less than the first switching threshold value, detecting the signal strength of at least one or more wireless access points. The first handover threshold is a preset RSSI threshold for triggering roaming (roaming) conditions when the terminal performs non-VoWiFi services, and may be recorded as value 5. That is, the signal strength of the wireless AP is lower than the first handover threshold, the terminal detects the signal strength of at least one or more other wireless APs in the communication range. And selecting the wireless access point with the largest signal strength from the at least one or more wireless access points as a target wireless access point, and switching to the target wireless access point. The process of the terminal performing wireless AP switching is a roaming process. In the moving process of the user, the terminal often spans from the coverage area of one wireless AP to the coverage area of another wireless AP. In order to avoid the situation that the network communication is interrupted when the mobile user switches between different wireless APs, a wireless roaming technology can be used.
After the handover to the target wireless access point, the method further comprises: and updating the parameters of the wireless access point according to the parameters of the target wireless access point.
Specifically, that is, when the terminal is switched to a new wireless AP, the terminal updates the parameters of the terminal-side wireless access point according to the new wireless AP. Parameters of the new wireless AP, such as power, signal quality, stability, occupied channel, etc.
It can be seen that, after detecting the signal strength of the wireless AP, and if the signal strength of the wireless access point is smaller than the first handover threshold, the terminal detects the signal strength of at least one or more wireless access points. And switches to the wireless AP with the strongest signal strength. And the middle end of the VoWiFi service is avoided by detecting and quickly switching to the wireless AP with better performance.
In one possible example, the data sent by the terminal is first data; the threshold value for determining whether to adjust the transmission power comprises a second transmission power threshold value, the switching parameter threshold value of the terminal comprises a second switching threshold value, and the indication information comprises a first indication information threshold value; the data sent by the terminal is second data; the sending power threshold of the terminal comprises a first sending power threshold, the switching parameter threshold of the terminal comprises a first switching threshold, and the indication information comprises a second indication information threshold.
Specifically, it can be understood that when the data sent by the terminal is the first data, that is, when the terminal performs the VoWiFi service, the sending power threshold of the terminal, that is, the threshold triggering the increase of the sending power, is the second sending power threshold, and may be denoted as Value 1; the handover parameter threshold of the terminal, that is, the signal strength threshold triggering roaming condition, includes a second handover threshold, which may be denoted as Value 2; the indication information is that the threshold value enabling the RTS or CTS-to-self strategy comprises a first indication information threshold value (a threshold value enabling the CTS-to-self strategy).
The data sent by the terminal is the second data, that is, when the terminal performs the non-VoWiFi service: the transmission power threshold of the terminal, that is, the threshold triggering the increase of the transmission power, is a first transmission power threshold, and may be denoted as Value 4; the handover parameter threshold of the terminal, that is, the signal strength threshold triggering roaming condition, includes a first handover threshold, which may be denoted as Value 5; the indication information is that the threshold value for enabling the RTS or CTS-to-self strategy comprises a second indication information threshold value (threshold value for enabling the RTS strategy).
Therefore, the terminal presets a network configuration parameter threshold in advance, so that the terminal can adjust the network configuration parameters according to different network environment parameters after detecting the network environment parameters, and the network environment of the terminal VoWiFi service is optimized.

Further, if the signal strength of the terminal is lower than the signal strength threshold of the terminal, adjusting the transmission power of the data; if the signal strength of the terminal is higher than or equal to the signal strength threshold of the terminal, the adjustment of the transmission power is not performed.

It is also possible, as shown in fig. 3, to enable the threshold value of the RTS or CTS-to-self protection strategy (TH _ R) equal to value3, i.e. to enable the threshold value of the CTS-to-self protection strategy when TH _ R is value 3. Or if the threshold value for detecting the sending indication information is equal to the threshold value of the second indication information, sending the second indication information. It is also possible, as shown in fig. 3, to enable the threshold value of the RTS or CTS-to-self protection strategy (TH _ R) equal to value6, i.e. to enable the threshold value of the CTS-to-self protection strategy when TH _ R is value 6.

And can also be used for updating the wireless AP parameters of the terminal according to the parameters of the target wireless access point.
