The network architecture of 5G includes two types of independent SAs (stand-alone networking) and NSAs (Non-stand-alone networking) combined with 4G. And SA: the new 5G network is established, and comprises a new base station, a backhaul link and a core network. NSA: non-independent networking refers to deployment of a 5G network using existing 4G infrastructure. The 5G carrier based on the NSA architecture carries only user data, and its control signaling is still transmitted through the 4G network. In the initial 5G period, NSA is a preference, so that a situation in which a 4G network and a 5G network coexist occurs. When the 4G network and the 5G network coexist, if the working frequency band of the 5G network coincides with the working frequency band of the 4G network or a harmonic part thereof, and the 4G network generates harmonic interference to the 5G network, the receiving performance in the working frequency band of the 5G network is affected.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, a terminal control method according to an embodiment of the present invention includes:
the network in which the terminal operates may be a 5G network, a 4G network, and the like, and each operating network includes a plurality of network frequency bands. Taking a 4G network and a 5G network as an example, a 5G carrier based on an NSA architecture only carries user data, and a control signaling of the 5G carrier is still transmitted through the 4G network, so that a situation that the 4G network and the 5G network coexist may occur, that is, a terminal may simultaneously operate in a certain frequency band of the 4G network and a certain frequency band of the 5G network.
after the network frequency band in which the terminal currently works is obtained, whether the terminal simultaneously works in two network frequency bands is judged, if the terminal simultaneously works in a first frequency band of a first network and a second frequency band of a second network, the possibility of interference of the two frequency bands is considered, and whether the first frequency band generates harmonic interference on the second frequency band needs to be further determined.
The embodiment of the present invention is described by taking an example that a terminal simultaneously operates in an LTE B3 frequency band of a 4G network and an n78 frequency band of a 5G network, and a second harmonic frequency range of the LTE B3 frequency band is: 3420MHz to 3570 MHz; the frequency range of the n78 frequency band is: 3.3-3.8 GHz; when the LTE B3 band and the n78 band operate simultaneously, the second harmonic of the LTE B3 band will be partially within the n78 band, and the LTE B3 band will generate harmonic interference to the n78 band, which will affect the receiving performance of the n78 band.
103, accessing a harmonic filtering unit in a first radio frequency path of the first network under the condition that the first frequency band generates harmonic interference on the second frequency band; and/or switching a first antenna connected with the first radio frequency path and/or switching a second antenna connected with a second radio frequency path of a second network, wherein the isolation between the first antenna and the second antenna after switching is greater than the isolation between the first antenna and the second antenna before switching.
In this embodiment, when it is determined that the first frequency band generates harmonic interference on the second frequency band, in order to ensure a receiving effect of the second frequency band, the harmonic filtering unit is controlled to be accessed in the first radio frequency path of the first network, and the harmonic filtering unit is configured to filter a second harmonic generated in the first frequency band of the first network, so as to eliminate the harmonic interference of the first frequency band on the second frequency band by a method of suppressing the second harmonic.
Or, under the condition that it is determined that the first frequency band generates harmonic interference on the second frequency band, in order to guarantee the receiving effect of the second frequency band, the switching of the first antenna connected with the first radio frequency path and/or the switching of the second antenna connected with the second radio frequency path is controlled, so that the isolation between the access antennas of the two radio frequency paths is improved, the harmonic interference generated by the first frequency band on the second frequency band can be reduced, and the receiving effect of the second network is guaranteed.
According to the embodiment of the invention, under the condition that the terminal simultaneously works in the first frequency band of the first network and the second frequency band of the second network and the first frequency band generates harmonic interference on the second frequency band, the second harmonic generated by the first frequency band is filtered out by controlling the harmonic filtering unit to be accessed into the first radio frequency channel of the first network, or the isolation between the access antennas of the two radio frequency channels is improved, so that the harmonic interference of the first frequency band on the second frequency band is reduced or eliminated, and the receiving effect of the second network is effectively ensured.
It should be noted that the harmonic filtering unit may be a notch unit. Taking the n78 frequency band of the 5G network and the LTE B3 frequency band of the 4G network as examples, as shown in fig. 2, the non-independent networking architecture of LTE +5G NR includes: the device comprises a baseband processor, a radio frequency path of a 4G network and a radio frequency path of a 5G network, wherein the radio frequency paths are connected with the baseband processor; wherein the baseband processor: the device is responsible for processing communication data and controlling the working state of a device of a radio frequency channel according to interaction information with a network;
the radio frequency path of the 4G network comprises:
4G transceiver: and the baseband processor is in communication connection with the baseband processor and is used for modulating and demodulating 4G radio frequency signals and modulating low-frequency signals into high-frequency signals to be output. Meanwhile, the received high-frequency signal can be subjected to frequency reduction to be a low-frequency signal and then is sent to a baseband processor for processing;
b3 duplexer: the method is used for combining an LTE B3 transmitting path and a receiving path into one path;
double pole double throw switch: the four terminals including RF1, RF2, RF3 and RF4 can work in two states according to control signals. Wherein, state 1: RF1 communicates with RF2, RF3 communicates with RF 4; state 2: RF1 communicates with RF3, RF2 communicates with RF 4;
a notch unit: as a harmonic filtering unit in a radio frequency path, the filter can effectively attenuate second harmonics generated in an LTE B3 frequency band, but can cause certain loss of an LTE B3 transmission signal; as shown in fig. 2, when the double pole double throw switch operates in state 1 where RF1 is in communication with RF2 and RF3 is in communication with RF4, the notch cell does not participate in the operation in the radio frequency path of the 4G network; when the double-pole double-throw switch works in a state 2 that RF1 is communicated with RF3 and RF2 is communicated with RF4, the trap unit is connected into a radio frequency path of the 4G network and is used as the harmonic filtering unit to filter out second harmonics generated in an LTE B3 frequency band;
4G antenna change-over switch: which Antenna (ANT) the 4G network operates in can be selected according to the control signal, and fig. 2 exemplifies four antennas of 4G ANT1, 4G ANT2, 4G ANT3, and 4G ANT 4.
The radio frequency path of the 5G network comprises:
5G transceiver: modulating and demodulating the 5G radio frequency signal, modulating a low-frequency signal into a high-frequency signal and outputting the high-frequency signal, and simultaneously reducing the frequency of the received high-frequency signal into a low-frequency signal to be sent to a baseband processor for processing;
n78 switch, N78 is Time Division Duplex (TDD) mode, used for switching transmitting and receiving path;
5G antenna change-over switch: which antenna the 5G signal operates on can be selected according to the control signal, and fig. 2 exemplifies four antennas, 5G ANT1, 5G ANT2, 5G ANT3, and 5G ANT 4.
Taking an n78 frequency band of a 5G network and an LTE B3 frequency band of a 4G network as examples, the terminal control method of the embodiment of the present invention may be implemented based on a non-independent networking architecture shown in fig. 2, and when the terminal simultaneously operates in an LTE B3 frequency band and an n78 frequency band and the LTE B3 frequency band generates harmonic interference on the n78 frequency band, the notch unit is accessed in a radio frequency path of the 4G network by controlling, so as to filter out a second harmonic generated in the LTE B3 frequency band, and eliminate the harmonic interference of the LTE B3 frequency band on the n78 frequency band.
Specifically, after step 101, the method further comprises:
and under the condition that the terminal only works in a first network or a second network or the first frequency band does not generate harmonic interference on the second frequency band, controlling a harmonic filtering unit in the first radio frequency path to perform bypass connection.
Under the condition that only the first network or the second network works and no harmonic interference exists at the moment, controlling a harmonic filtering unit in the first radio frequency channel to perform bypass connection; and if the terminal works in a first frequency band of the first network and a second frequency band of the second network at the same time, but the first frequency band does not generate harmonic interference on the second frequency band, controlling a harmonic filtering unit in the first radio frequency channel to perform bypass connection. Wherein the controlling of the harmonic filtering unit in the first radio frequency path to perform the bypass connection means controlling the harmonic filtering unit not to participate in the operation in the first radio frequency path. Taking the n78 frequency band of the 5G network and the LTE B3 frequency band of the 4G network as examples, as shown in fig. 2, controlling the harmonic filtering unit in the first radio frequency path to perform bypass connection means: and controlling the double-pole double-throw switch to work in a state 1 that RF1 is communicated with RF2, and RF3 is communicated with RF4, wherein the trap unit does not participate in the work in the radio frequency path of the 4G network.
According to the embodiment, when the terminal only works in one network frequency band or two frequency bands working simultaneously do not generate harmonic interference, the harmonic filtering unit does not participate in working, the insertion loss of the first radio frequency channel can be reduced, and the transceiving performance is improved.
Further, step 102 comprises:
judging whether the second harmonic of the first frequency band is in the receiving channel range of the second frequency band; and if the second harmonic of the first frequency band is in the receiving channel range of the second frequency band, determining that the first frequency band generates harmonic interference on the second frequency band.
When the terminal simultaneously works in a first frequency band of a first network and a second frequency band of a second network, if the second harmonic of the first frequency band is in the frequency range of a receiving channel of the second frequency band, namely the frequency range of the second frequency band is partially overlapped with the frequency range of the first frequency band, the first frequency band is considered to generate harmonic interference on the second frequency band; if the frequency range of the second frequency band does not coincide with the frequency range of the first frequency band, it is considered that the reception performance of the network is not affected even if the terminal simultaneously operates in the first frequency band of the first network and the second frequency band of the second network.
Further, step 103 comprises:
under the condition that harmonic interference is generated on a second frequency band by a first frequency band, a first control signal is sent to a first radio frequency channel of the first network; the first control signal carries indication information for controlling the harmonic filter unit to be in a working state.
Under the condition that the terminal simultaneously works in a first frequency band of a first network and a second frequency band of a second network and harmonic interference is generated on the second frequency band by the first frequency band, a baseband processor of the terminal sends a first control signal to a first radio frequency channel of the first network to control a harmonic filtering unit in the first radio frequency channel to participate in working, secondary harmonic generated by the first frequency band is filtered, the harmonic interference on the second frequency band by the first frequency band is eliminated, and then the receiving effect of the second network is guaranteed.
The foregoing embodiment describes a method for eliminating harmonic interference of a first frequency band to a second frequency band by controlling a first radio frequency path of a first network to access a harmonic filtering unit when a terminal simultaneously operates in the first frequency band of the first network and in a second frequency band of a second network, and the first frequency band generates harmonic interference to the second frequency band.
Specifically, before step 101, the method further comprises:
isolation information between an antenna of a first radio frequency path of a first network and an antenna of a second radio frequency path of a second network is stored. In the terminal, the pre-measured isolation information between each antenna of the first radio frequency channel of the first network and each antenna of the second radio frequency channel of the second network is stored.
In order to avoid that the terminal affects the receiving performance when operating in two network frequency bands simultaneously, optionally, as shown in fig. 3, switching the first antenna connected to the first radio frequency path under the condition that the first frequency band generates harmonic interference on the second frequency band includes:
and under the condition that the first frequency band generates harmonic interference on the second frequency band, a baseband processor of the terminal acquires information of a second antenna currently connected with a second radio frequency channel by inquiring a control signal.
And the baseband processor of the terminal selects a second antenna of a second radio frequency channel with the highest isolation of the first antenna currently connected with the first radio frequency channel according to the information of the first antenna by calling antenna isolation data stored in the terminal, and controls the second radio frequency channel to be connected to the second antenna.
After determining the first antenna with the highest isolation from the second antenna, the terminal may send a control signal to a first radio frequency path of the first network, and control the first radio frequency path to be connected to the first antenna. Therefore, the isolation between the first antenna connected with the first radio frequency path and the second antenna connected with the second radio frequency path is increased, so that the harmonic interference generated by the first frequency band to the second frequency band can be reduced, and the receiving effect of the second network is guaranteed.
Optionally, as shown in fig. 4, in a case where the first frequency band generates harmonic interference to the second frequency band, switching a second antenna connected to a second radio frequency path of a second network includes:
and under the condition that the first frequency band generates harmonic interference on the second frequency band, a baseband processor of the terminal acquires information of a first antenna currently connected with a first radio frequency channel by inquiring a control signal.
And the baseband processor of the terminal selects a second antenna of a second radio frequency channel with the highest isolation of the first antenna currently connected with the first radio frequency channel according to the information of the first antenna by calling antenna isolation data stored in the terminal, and controls the second radio frequency channel to be connected to the second antenna.
After determining the second antenna with the highest isolation from the first antenna, the terminal may send a control signal to a second radio frequency path of a second network, and control the second radio frequency path to be connected to the second antenna. Therefore, the isolation between the first antenna connected with the first radio frequency path and the second antenna connected with the second radio frequency path is increased, so that the harmonic interference generated by the first frequency band to the second frequency band can be reduced, and the receiving effect of the second network is guaranteed.
It should be noted that, in the embodiment of the present invention, when the terminal simultaneously operates in the first frequency band of the first network and the second frequency band of the second network, and the first frequency band generates harmonic interference on the second frequency band, in order to eliminate or reduce the harmonic interference on the second frequency band by the first frequency band, and further ensure the receiving effect of the second network, the following manners may be implemented, but are not limited to:
in the first mode, the harmonic filtering unit is accessed by controlling the first radio frequency channel of the first network, so that the harmonic interference of the first frequency band to the second frequency band is eliminated, and the receiving effect of the second network is further ensured.
In a second mode, the first antenna is connected to the second antenna by controlling a second radio frequency path of the second network; the first antenna is the antenna with the highest antenna isolation degree with the second antenna in the antennas of the first radio frequency channel.
In a third mode, the second antenna is connected to the first antenna by controlling a first radio frequency path of the first network; and the second antenna is the antenna with the highest antenna isolation degree with the first antenna in the antennas of the second radio frequency channel.
The three modes can be realized separately or jointly. When the three modes are jointly implemented, starting from two aspects of suppression of second harmonic of a first frequency band and antenna isolation of a first radio frequency channel or a second radio frequency channel, when a terminal only works in a first network or a second network or the first frequency band does not generate harmonic interference on the second frequency band, a harmonic filtering unit does not participate in working, and a working mode with low insertion loss is preferentially selected, so that the transceiving performance of the network is ensured, and the communication quality is ensured and the power consumption is reduced; when the terminal works in the first frequency band of the first network and the second frequency band of the second network at the same time, the receiving effect of the network is effectively guaranteed by filtering out second harmonic and improving the isolation of the antenna.
