Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, fig. 1 is one of flowcharts of a method for reducing coexistence interference of multiple networks according to an embodiment of the present invention, and as shown in fig. 1, the method for reducing coexistence interference of multiple networks according to an embodiment of the present invention is applied to a terminal, and includes the following steps:
Specifically, the first network and the second network each refer to a wireless network, such as a 2G network, a 3G network, a 4G network, or a 5G network, or the like. The terminal detects the terminal and judges whether to adopt the first network and the second network to communicate at the same time, if so, the terminal acquires the communication parameters of at least one of the first network and the second network.
Acquiring the communication parameters of at least one of the first network and the second network includes acquiring the communication parameters of the first network, acquiring the communication parameters of the second network, or acquiring the communication parameters of the first network and the second network. The communication parameter may be a frequency employed in network communication or network signal quality, etc.
102, if the communication parameters meet the preset conditions, sending a notification message to a base station; the notification message is used for notifying the base station to control communication transmission of the target network of the terminal, wherein the target network is the first network or the second network.
The preset condition can be set according to actual requirements, and when the communication parameters meet the preset condition, the interference between the first network and the second network is indicated.
After judging that the communication parameters meet the preset conditions, determining a target network, wherein the target network is a first network or a second network. When the notification message is sent to the base station, the notification message may be sent by using the target network, or may not be sent by using the target network. For example, when the target network is a first network, the notification message may be sent through the first network or may be sent through a second network; when the target network is the second network, the notification message may be sent through the second network or may be sent through the first network. The purpose of sending the notification message to the base station is to notify the base station to control communication transmission of the target network of the terminal, for example, notify the base station that the base station needs to reduce the frequency (frequency, i.e., the number of service data frames sent per unit time) of sending the service data frames to the target network, or stop sending the service data frames to the target network.
The terminal receives a response message returned by the base station, wherein the response message is a response message for the notification message, and the response message can be a silence descriptor frame. After receiving the response message, the terminal may reduce the frequency of communication transmission through the target network or stop communication transmission through the target network.
Because the terminal controls the communication transmission through the target network, when the target network is the first network, the terminal controls the communication transmission of the first network, so that the interference of the first network to the second network can be effectively reduced, and at the moment, the terminal mainly adopts the second network to perform the communication transmission.
In the embodiment of the present invention, the terminal may be a mobile terminal capable of simultaneously adopting two wireless networks for communication, for example: a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), a mobile internet Device (Mobile Internet Device, MID) or a Wearable Device (wearmable Device), etc.
In the method for reducing coexistence interference of multiple networks in the embodiment of the invention, if the terminal simultaneously adopts the first network and the second network to communicate, the communication parameters of at least one of the first network and the second network are obtained; if the communication parameters meet the preset conditions, a notification message is sent to the base station; the notification message is used for notifying the base station to control communication transmission of the target network of the terminal, wherein the target network is the first network or the second network; and receiving a response message returned by the base station for the notification message to reduce the communication transmission frequency of the target network or stop the communication transmission of the target network, so that when the first network and the second network have interference, the interference generated by the first network or the second network can be effectively reduced by controlling the communication transmission of the first network or the second network, the terminal performance is improved, the terminal power consumption is reduced, the service life is prolonged, and the user experience is improved.
Further, after step 103, the method further includes:
and receiving the silence descriptor frame sent by the base station so as to enable the target network to keep communication connection with the base station.
The terminal will remain connected to the base station through the silence descriptor frame, at which point the target network is in a suspended silence state. The sending frequency of the silence descriptor frame sent to the terminal by the base station only needs to be enough to keep basic connection with the target network, so that the interference caused by the target network and the power consumption of the target network on the terminal are reduced as much as possible.
Referring to fig. 2, fig. 2 is a second flowchart of a method for reducing coexistence interference of multiple networks according to the embodiment of the present invention, as shown in fig. 2, when a communication parameter is network signal quality of a first network, the method for reducing coexistence interference of multiple networks according to the embodiment of the present invention includes the following steps:
In this step, the communication parameter is the network signal quality of the first network. The network signal quality may be an indicator that may reflect the signal strength received by the terminal, such as a received signal strength indicator (Received Signal Strength Indication, abbreviated RSSI) or a reference signal received power (Reference Signal Receiving Power, abbreviated RSRP).
In this step, the network signal quality of the first network is obtained. In this embodiment, the network signal quality uses RSSI, and the terminal reads the RSSI value from the data packet received from the first network.
The preset quality threshold can be set according to actual conditions. For example, when the network signal quality takes the value of RSSI, the preset quality threshold may be-90 dbm. If the RSSI value of the first network is A, if A > -90dbm, the signal quality of the first network is considered to be good, and the data service of the terminal is put on the first network, so that the second network is required to be used as a target network; if A is less than or equal to-90 dbm, the network environment of the first network is considered to be poor, and the data interaction with normal throughput cannot be supported, so that the use proportion of the first network can be reduced, and the first network is taken as a target network.
For example, when the first network is a 5G network and the second network is a 4G network, if the RSSI value of the 5G network is A, if A is-90 dbm, the signal quality of the 5G network is considered to be good, and then the data service of the terminal is placed in the 5G network, and the 4G network is taken as a target network; if A is less than or equal to-90 dbm, the network environment of the 5G network is considered to be poor. When the 5G network is used on the terminal, the power consumption is larger, when the network environment is worse, the error rate of the data service is increased, the data packet is retransmitted for many times, and the radio frequency transmitting power is increased, so that the use proportion of the 5G network can be reduced, the use proportion of the 4G network with lower power consumption and wider coverage is increased, the 5G network is used as a target network, the transmission and the reception of the data service of the 5G network are reduced or stopped, and the overall power consumption of the terminal is further reduced.
The descriptions of this step and step 103 are identical, and the descriptions of step 103 are specifically referred to, and are not repeated here.
In the method for reducing coexistence interference of multiple networks in the embodiment of the invention, if the network signal quality of the first network is not greater than the preset quality threshold, the first network is determined to be the target network, and the notification message is sent to the base station to reduce the communication transmission frequency of the target network or stop the communication transmission of the target network, so that when the first network and the second network have mutual interference, the communication transmission of the network with good network signal quality is reserved, the interference generated by the first network or the second network can be effectively reduced, the terminal performance is improved, the terminal power consumption is reduced, the service life is prolonged, and the user experience is improved.
Referring to fig. 3, fig. 3 is a second flowchart of a method for reducing coexistence interference of multiple networks according to the embodiment of the present invention, as shown in fig. 3, when a communication parameter is frequency, the method for reducing coexistence interference of multiple networks according to the embodiment of the present invention includes the following steps:
The description of this step is identical to that of step 101, and specifically, the description of step 101 is referred to, and will not be repeated here.
The preset threshold is a positive number, and can be set according to actual conditions. The terminal can read the working frequency of the first network, namely the first frequency, from the data frame information received and transmitted through the first network; and reading the working frequency of the second network, namely the second frequency, from the data frame information received and transmitted by the second network, comparing whether the first frequency and the second frequency meet the preset condition, and if the preset condition is met, causing interference between the first network and the second network.
For example, when the first network is a 5G network and the second network is a 4G network, if the operating frequency of the 4G network is in the B3 band and the operating frequency of the 5G network is in the N77 or N78 band, interference exists between the 4G network and the 5G network. If the operating frequency of the 4G network is in the B7 band and the operating frequency of the 5G network is in the N77 or N78 band, interference exists between the 4G network and the 5G network.
In addition, if the radio frequency of the 4G network (i.e., the operating frequency of the 4G network) or the radio frequency multiple of the 4G network (i.e., the multiple of the radio frequency) is the same as or similar to the radio frequency of the 5G network (i.e., the operating frequency of the 5G network) (when the two are similar to each other, the absolute value of the difference between the two is smaller than the preset threshold), there is interference between the 4G network and the 5G network.
After determining that there is interference between the first network and the second network, it is determined which of the first network and the second network is the target network. For example, when there is interference between the 4G network and the 5G network, either the 4G network or the 5G network may be determined as the target network. When the 4G network is determined to be a target network, the terminal can send a notification message to the base station through the 4G network, and can also send the notification message to the base station through the 5G network; when the 5G network is determined as the target network, the terminal may transmit a notification message to the base station through the 5G network, or may transmit a notification message to the base station through the 4G network. Preferably, since the 5G network is more advantageous in communication quality than the 4G network, the target network is determined as the 4G network, and communication transmission of the 4G network is controlled to preferentially satisfy the communication transmission of the 5G network.
For example, when there is interference between the 4G network and the 5G network, the 4G network is determined as the target network. The response message is a silence descriptor frame (i.e., SID frame), and after receiving the silence descriptor frame, the terminal reduces or stops sending or receiving data traffic frames on the 4G network.
At this time, the radio frequency signal transmission and reception of the 4G network will be greatly reduced, and only the silence descriptor frame maintains the connection between the 4G network and the base station, so that the interference of the 4G network to the 5G network can be greatly reduced, and the sensitivity of the 5G network to receive signals is improved.
According to the method for reducing the coexistence interference of multiple networks, through comparing the first frequency of the first network with the second frequency of the second network, if the absolute value of the difference between the first frequency and the second frequency is smaller than the preset threshold, or the absolute value of the difference between the multiple of the first frequency and the multiple of the second frequency is smaller than the preset threshold, a notification message is sent to a base station to reduce the communication transmission frequency of the target network, or stop the communication transmission of the target network, so that when the frequencies used by the first network and the second network are interfered with each other, the interference generated by the first network or the second network can be effectively reduced, the terminal performance can be improved, the terminal power consumption can be reduced, the service life can be prolonged, and the user experience can be improved.
Further, as shown in fig. 4, step 302 includes:
In this step, when determining the target network, the method of determining the target network in step 302 may be adopted, which is not described herein.
For example, the first network is a 5G network, the second network is a 4G network, and the second network is determined as the target network.
In this embodiment, the communication parameters include not only frequency, but also network signal quality when the terminal uses the first network to communicate. After determining the target network in step 3021, further determination of the network signal quality of the target network is required to finally determine the target network.
For example, the first network is a 5G network, the second network is a 4G network, and after the second network is determined as the target network, the network signal quality of the 5G network is determined in this step.
If the RSSI value of the 5G network is A, when A is minus 90dbm, the signal quality of the 5G network is considered to be good, at the moment, the data service of the terminal is put in the 5G network, and the 4G network is taken as a target network; if A is less than or equal to-90 dbm, the network environment of the 5G network is considered to be poor. When the 5G network is used on the terminal, the power consumption is larger, when the network environment is worse, the error rate of the data service is increased, the data packet is retransmitted for many times, and the radio frequency transmitting power is increased, so that the use proportion of the 5G network can be reduced, the use proportion of the 4G network with lower power consumption and wider coverage is increased, the 5G network is used as a target network, the transmission and the reception of the data service of the 5G network are reduced or stopped, and the overall power consumption of the terminal is further reduced.
In this embodiment, the target network is determined through the first frequency of the first network and the second frequency of the second network, and then whether the network signal quality of the target network is greater than a preset quality threshold is determined to finally determine whether the target network is the first network or the second network, so that the communication quality of the terminal can be ensured and the user experience can be improved on the premise of reducing the interference caused by the first network or the second network.

Specifically, the determination of the target network is performed by the terminal, and the relevant steps of determining the target network by the terminal in the first embodiment can be referred to specifically. The first network and the second network each refer to a wireless network, such as a 2G network, a 3G network, a 4G network, or a 5G network, etc.
The terminal detects the terminal and judges whether to adopt the first network and the second network to communicate at the same time, if so, the terminal acquires the communication parameters of at least one of the first network and the second network.
Acquiring the communication parameters of at least one of the first network and the second network includes acquiring the communication parameters of the first network, acquiring the communication parameters of the second network, or acquiring the communication parameters of the first network and the second network. The communication parameter may be a frequency employed in network communication or network signal quality, etc.
The base station may know that, according to the notification message, it is required to control communication transmission of the target network of the terminal, for example, reduce the frequency of communication transmission of the target network, or stop communication transmission of the target network. And the base station sends a response message to the terminal after receiving the notification message sent by the terminal. The response message may be a silence descriptor frame.
The method for reducing the coexistence interference of various networks receives the notification message sent by the terminal; and sending a response message aiming at the notification message to the terminal, so that the terminal reduces the communication transmission frequency of the target network or stops the communication transmission of the target network according to the response message. Therefore, when the first network and the second network which are used on the terminal simultaneously have interference, the interference generated by the first network or the second network can be effectively reduced by controlling the communication transmission of the first network or the second network, the performance of the terminal is improved, the power consumption of the terminal can be reduced, the use time is prolonged, and the user experience is improved.
Further, after step 402, the method further includes:
and sending a silence descriptor frame to the target network to maintain a communication connection with the target network.
The base station will remain connected to the terminal through the silence descriptor frame, at which point the target network is in a suspended silence state. The sending frequency of the silence descriptor frame sent to the terminal by the base station only needs to be enough to keep basic connection with the target network, so that the interference caused by the target network and the power consumption of the target network on the terminal are reduced as much as possible.
