The embodiment of the invention provides an interference processing method which is applied to terminal equipment. Referring to fig. 2, fig. 2 is a flowchart of an interference processing method provided in an embodiment of the present invention, as shown in fig. 2, including the following steps:

step 201, detecting whether a first target frequency point interferes with a first working frequency band of a positioning module of a terminal device under the condition that the terminal device is connected with a first network and a second network, wherein the first target frequency point is a frequency point obtained after intermodulation of the working frequency point of the first network and the working frequency point of the second network.

In this embodiment, the terminal Device may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer), a personal digital assistant (personal digital assistant, PDA for short), or a Wearable Device.

The first network and the second network may be any two different networks. For example, under EN-DC architecture, the first network may be a 5G network and the second network may be a 4G network.

The first target frequency point may be a frequency point obtained by intermodulation between the operating frequency point of the first network and the operating frequency point of the second network. For example, if the working frequency point of the first network is f1 and the working frequency point of the second network is f2, the first target frequency point may include at least one of mxf1+nf2 and mxf 1-n f2, where m and n are both positive integers.

The positioning module can be a GPS module, a Beidou satellite navigation system module or a Galileo positioning system module and the like. The first operating frequency band of the positioning module may be any operating frequency band of all frequency bands in which the positioning module currently operates. For example, taking the positioning module as a GPS module as an example, the first operating frequency band may be L1 or L5.

In practical application, the terminal device can be connected with the first network and the second network at the same time, and the positioning module is in a working state, and whether the frequency points obtained after intermodulation of the working frequency points of the first network and the working frequency points of the second network interfere with the first working frequency band of the positioning module is detected. For example, whether a frequency point obtained after intermodulation of an operating frequency point of the first network and an operating frequency point of the second network is located in a first operating frequency band of the positioning module or whether a frequency point obtained after intermodulation of the operating frequency point of the first network and the operating frequency point of the second network is relatively close to the first operating frequency band of the positioning module is detected.

Step 202, sending a frequency point switching request to a network side device to switch the working frequency point of a target network under the condition that the first target frequency point interferes with the first working frequency band;

In this embodiment, the network-side device may be a base station, for example: macro station, LTE eNB, 5G NR NB, gNB, etc.; the network side device may also be a small station, such as a Low Power Node (LPN) pico, femto, or an Access Point (AP). The base station may be a network node formed by a Central Unit (CU) and a plurality of TRPs managed and controlled by the Central Unit. Note that, in this embodiment, the specific type of the network side device is not limited.

Specifically, when the frequency points obtained after intermodulation of the working frequency points of the first network and the working frequency points of the second network interfere with the first working frequency band, a frequency point switching request, which may also be called a channel switching request, may be sent to the network side device to switch at least one working frequency point of the first network and the second network, so as to reduce the influence of the frequency points obtained by intermodulation of the working frequency points of the first network and the second network on the working frequency band of the positioning module. For example, the operating frequency point of at least one of the first network and the second network may be switched, so that the frequency point obtained by intermodulation of the operating frequency points of the first network and the second network after switching is not located in the operating frequency band of the positioning module, or the frequency point obtained by intermodulation of the operating frequency points of the first network and the second network after switching is far away from the operating frequency band of the positioning module, or the like.

It should be noted that, in this embodiment, at least one candidate working frequency point that can reduce the influence on the working frequency band of the positioning module may be indicated to the network side device by the terminal device, so as to be referred to by the network side device; the information such as the working frequency band of the positioning module can be reported to the network side equipment, and the working frequency point which can reduce the influence on the working frequency band of the positioning module can be determined through the network side equipment.

Alternatively, the present embodiment may execute the above step 201 and step 202 when the positioning module of the terminal device is in an operating state.

According to the interference processing method provided by the embodiment of the invention, under the condition that the frequency points obtained after intermodulation of the working frequency points of the first network and the working frequency points of the second network generate interference to the working frequency band of the positioning module, the working frequency points of at least one of the first network and the second network are switched, so that the influence of the frequency points obtained by intermodulation of the working frequency points of the first network and the second network on the working frequency band of the positioning module is reduced, the interference of the transmitting signals of the first network and the transmitting signals of the second network on the receiving signals of the positioning module can be reduced, and the positioning performance of the positioning module is improved.

Optionally, the step 201, that is, the detecting whether the first target frequency point generates interference to the first operating frequency band of the positioning module of the terminal device may include:

detecting whether the first target frequency point is located in the first working frequency band;

step 202, that is, when the first target frequency point generates interference to the first operating frequency band, sends a frequency point switching request to a network side device to switch the operating frequency point of the target network, where the step includes:

transmitting a frequency point switching request to network side equipment under the condition that the first target frequency point is located in the first working frequency band so as to switch the working frequency point of the target network; the second target frequency point is located outside the first working frequency band.

In practical application, because the energy of the received signal of the positioning module is relatively low, under the condition that the frequency point obtained after intermodulation of the working frequency point of the first network and the working frequency point of the second network is located in the working frequency band of the positioning module, the frequency point obtained after intermodulation of the working frequency point of the first network and the working frequency point of the second network can cause larger interference to the received signal of the positioning module.

Therefore, in the case that the frequency point obtained after intermodulation of the working frequency point of the first network and the working frequency point of the second network is within the first working frequency band, the working frequency point of at least one of the first network and the second network is switched, so that the frequency point obtained after intermodulation of the working frequency points of the first network and the second network is not within the first working frequency band, interference of the transmitting signals of the first network and the transmitting signals of the second network on the receiving signals of the positioning module can be reduced, and performance of the positioning module is improved.

It should be noted that, when the frequency point obtained after intermodulation between the operating frequency point of the first network and the operating frequency point of the second network is outside the first operating frequency band, the process may be returned to execute step 201, or the process may be ended, or whether the frequency point obtained after intermodulation between the operating frequency point of the first network and the operating frequency point of the second network is relatively close to the first operating frequency band may be further determined.

Optionally, the method may further include:

if the difference value between the first target frequency point and the first frequency point in the first working frequency band is smaller than a preset difference value, sending a frequency point switching request to network side equipment so as to switch the working frequency point of the target network;

the difference value between the second target frequency point and the second frequency point is greater than or equal to the preset difference value, the first frequency point is the frequency point closest to the first target frequency point in the first working frequency band, and the second frequency point is the frequency point closest to the second target frequency point in the first working frequency band.

In this embodiment, the first frequency point may be a frequency point closest to a first target frequency point in the first working frequency band, for example, in a case where the first target frequency point is greater than each frequency point in the first working frequency band, the first frequency point may be a maximum frequency point of the first working frequency band; under the condition that the first target frequency point is smaller than each frequency point of the first working frequency band, the first frequency point can be the minimum frequency point of the first working frequency band. The preset difference value can be reasonably set according to practical situations, for example, 1MHZ, 0.5MHZ and the like.

In practical application, under the condition that the first target frequency point is not located in the first working frequency band, whether the difference between the first target frequency point and the first frequency point in the first working frequency band is smaller than a preset difference or not can be further judged. Specifically, when the difference between the first target frequency point and the first frequency point is smaller than a preset difference, a frequency point switching request may be sent to the network side device to switch at least one working frequency point of the first network and the second network, where the difference between the frequency point obtained by intermodulation of the working frequency points of the first network and the second network after switching and the second frequency point is greater than or equal to the preset difference, and the second frequency point is a frequency point closest to the frequency point obtained by intermodulation of the working frequency points of the first network and the second network after switching in the first working frequency band. Otherwise, the process may return to the execution of step 201, or the process may end.

Optionally, in this embodiment, the difference between the first target frequency point and each frequency point in the first working frequency band may also be calculated, and when at least one difference in the calculated differences is smaller than a preset difference, it is determined that the first target frequency point is relatively close to the first working frequency band, and at this time, the working frequency point of at least one of the first network and the second network may be switched. Alternatively, if no difference value is smaller than the preset difference value, the execution step 201 may be returned, or the flow may be ended.

Optionally, the embodiment may further determine, in combination with the received signal strength of the positioning module and whether the first target frequency point is closer to the first working frequency band, whether the first target frequency point interferes with the first working frequency band. For example, when the received signal strength of the positioning module is less than or equal to the threshold, and the first target frequency point is relatively close to the first working frequency band (for example, the difference between the first target frequency point and the first frequency point in the first working frequency band is less than a preset difference), it may be determined that the first target frequency point generates interference to the first working frequency band, and the working frequency point of at least one of the first network and the second network is switched, so as to reduce the influence on the working frequency band of the positioning module, otherwise, the execution of step 201 may be returned, or the flow may be ended. Thus, the accuracy of the interference detection result can be improved.

Optionally, the frequency point switching request may include a frequency point change amount of the target network;

or alternatively

The frequency point switch request may include candidate operating frequency points of the target network.

In an embodiment, the frequency point change amount of the target network may be carried in the frequency point switch request, so that the network side device may perform frequency point switch of the target network based on the frequency point change amount of the target network. The frequency point change amount may be determined based on the working frequency point of the first network, the working frequency point of the second network and the working frequency band of the positioning module, so as to ensure that the frequency point obtained by intermodulation of the working frequency point of the first network and the working frequency point of the second network after switching is not located in the first working frequency band, or the difference value between the frequency point obtained by intermodulation of the working frequency point of the first network and the working frequency point of the second network after switching and the second frequency point is greater than or equal to the preset difference value.

Taking dc_1a—n78a as an example, referring to fig. 3, the 4G operating frequency point of the terminal device is f _1A =1950mhz, 5g operating frequency point f _n78 = 3525.42MHz, second order intermodulation point f _{Intermodulation products} ＝f _n78 -f _1A Center work of GPS module=1575.42 MHzThe frequency point is f _GPS The frequency point after intermodulation is located in the receiving frequency band of the GPS, i.e. the working frequency band of the GPS, which interferes with GPS positioning.

In this case, the terminal device may initiate a channel switching request to the base station, for example, may let the 4G operating frequency point move up by 10MHz (not limited to 10MHz here) based on the current frequency point, so that the intermodulation frequency point is shown in the second row in fig. 3, and the intermodulation frequency point is f _{Intermodulation products} The frequency range is 1565.42MHz, which falls outside the GPS receiving frequency range and does not interfere with GPS positioning; or the 5G working frequency point is shifted up by 10MHz (not limited to 10MHz here) based on the current frequency point, so that the intermodulation frequency point can be shown as the third row in FIG. 3, and the intermodulation frequency point is f _{Intermodulation products} The frequency range of the antenna is 1585.42MHz, which falls outside the GPS receiving frequency range and does not interfere with GPS positioning.

It should be noted that, when the working frequency point of the first network and the working frequency point of the second network need to be switched, the frequency point changing amount may include the frequency point changing amount of the first network and the frequency point changing amount of the second network, so that the network side device may switch the working frequency point of the first network based on the frequency point changing amount of the first network, and switch the working frequency point of the second network based on the frequency point changing amount of the second network.

In practical application, the network side device may sequentially change the working frequency point of the target network based on the frequency point change amount until the changed frequency point is an available frequency point in the working frequency band of the target network. For example, the working frequency point of the first network is f _n78 The frequency point change amount is +f ₀ The working frequency point of the first network after the first change is f _n78 +f ₀ If the frequency point is an unavailable frequency point, changing the working frequency point of the first network to f again _n78 +2*f ₀ If the frequency point is an unavailable frequency point, changing the working frequency point of the first network to f again _n78 +3*f ₀ And the like, until the changed frequency point is an available frequency point in the n78 frequency band.

In another embodiment, the frequency point switching request may carry at least one candidate operating frequency point of the target network, where the at least one candidate operating frequency point may be determined based on an operating frequency point of the first network, an operating frequency point of the second network, and an operating frequency band of the positioning module, so as to ensure that a frequency point obtained by intermodulation between the operating frequency point of the first network and the operating frequency point of the second network after switching is not located in the first operating frequency band, or a difference between a frequency point obtained by intermodulation between the operating frequency point of the first network and the operating frequency point of the second network after switching and the second frequency point is greater than or equal to the preset difference. In this way, the network side device can select the available frequency point from the at least one candidate working frequency point to switch.

According to the method and the device, the frequency point change amount of the target network or the candidate working frequency point of the target network is indicated to the network side device through the terminal device, so that the network side device can conveniently and rapidly switch the frequency points of the target network, and the influence of the frequency points obtained by intermodulation of the working frequency points of the first network and the working frequency points of the second network after switching on the working frequency band of the positioning module can be reduced.

Optionally, before the step 202, that is, before the sending a frequency point switching request to the network side device to switch the working frequency point of the target network, the method may further include:

receiving available frequency point information sent by the network side equipment;

the available frequency point information comprises available frequency points in the working frequency band of the target network, and the candidate working frequency points comprise frequency points selected from the available frequency points.

In this embodiment, after the terminal device connects the first network and the second network, the network side device may send, to the terminal device, available frequency points in a working frequency band of the network to which the terminal device is connected every preset time length, where the preset time length may be set reasonably according to an actual situation; and the available frequency points in the working frequency band of the network requested by the terminal equipment can be sent to the terminal equipment under the condition of receiving the available frequency point acquisition request sent by the terminal equipment. Thus, the terminal equipment can select the candidate working frequency point from the available frequency points in the working frequency band of the target network and send the candidate working frequency point to the network side equipment, thereby improving the frequency point switching efficiency.

Optionally, before the receiving the available frequency point information sent by the network side device, the method may further include:

transmitting an available frequency point acquisition request to the network side equipment under the condition that the first target frequency point interferes with the first working frequency band;

the available frequency point obtaining request is used for obtaining available frequency points in the working frequency band of the target network.

In this embodiment, the terminal device may send an available frequency point acquisition request to the network side device under the condition that the first target frequency point interferes with the first working frequency band, so as to acquire an available frequency point in the working frequency band of the target network, which can save system resources.

The embodiment of the invention provides an interference processing method which is applied to network side equipment. Referring to fig. 4, fig. 4 is a flowchart of an interference processing method provided in an embodiment of the present invention, as shown in fig. 4, including the following steps:

step 401, receiving a frequency point switching request sent by a terminal device.

In this embodiment, the frequency point switching request may include information such as a frequency point change amount of the target network, a candidate working frequency point of the target network, or a working frequency band of the positioning module. The target network may include at least one of a first network and a second network to which the terminal device is connected.

Step 402, switching the working frequency point of the target network according to the frequency point switching request;

For example, if the frequency point switching request includes the working frequency band of the positioning module, the network side device may determine, based on the working frequency band of the positioning module, a frequency point that may reduce an influence on the working frequency band of the positioning module, and switch the working frequency point of the target network to the frequency point. For example, the network side device may determine the frequency point to be switched according to the working frequency band of the positioning module, the working frequency point of the first network, and the working frequency point of the second network, so as to ensure that the frequency point obtained by intermodulation between the working frequency point of the first network and the working frequency point of the second network after switching is not located in the first working frequency band, or that the difference between the frequency point obtained by intermodulation between the working frequency point of the first network and the working frequency point of the second network after switching and the second frequency point is greater than or equal to the preset difference.

If the frequency point switching request includes a frequency point change amount of the target network or a candidate working frequency point of the target network, the network side device may switch the working frequency point of the target network based on the frequency point change amount of the target network or the candidate working frequency point, for example, determine an available frequency point based on the frequency point change amount of the target network or the candidate working frequency point, and switch the working frequency point of the target network to be the frequency point.

According to the interference processing method provided by the embodiment of the invention, the network side equipment receives the frequency point switching request sent by the terminal equipment and switches the working frequency point of the target network according to the frequency point switching request, so that the influence of the frequency point obtained by intermodulation of the working frequency points of the first network and the second network on the working frequency band of the positioning module is reduced, the interference of the transmitting signal of the first network and the transmitting signal of the second network on the receiving signal of the positioning module can be reduced, and the positioning performance of the positioning module is improved.

the step 402, that is, the switching the operating frequency point of the target network according to the frequency point switching request, may include:

sequentially changing the working frequency points of the target network according to the frequency point changing amount until the changed frequency points are available frequency points;

And switching the working frequency point of the target network to be the changed frequency point.

In this embodiment, the frequency point change amount may be determined based on the working frequency point of the first network, the working frequency point of the second network, and the working frequency band of the positioning module, so as to ensure that the frequency point obtained by intermodulation between the working frequency point of the first network and the working frequency point of the second network after switching is not located in the first working frequency band, or that the difference between the frequency point obtained by intermodulation between the working frequency point of the first network and the working frequency point of the second network after switching and the second frequency point is greater than or equal to the preset difference.

According to the embodiment of the invention, the network equipment performs frequency point switching based on the frequency point change amount of the target network, so that the frequency point switching efficiency can be improved, and the influence of the frequency point obtained by intermodulation of the working frequency point of the first network and the working frequency point of the second network after switching on the working frequency band of the positioning module can be reduced.

Optionally, the frequency point switching request may include a candidate working frequency point of the target network;

switching the working frequency point of the target network to be a target candidate frequency point;

the target candidate frequency point is a frequency point in the candidate working frequency point.

In this embodiment, the candidate operating frequency points may include one or at least two operating frequency points.
