Description
Technical Field
The present invention relates to the field of communications, and in particular, to an interference processing method and apparatus, and a mobile terminal.
Background
With the popularization of mobile terminals, there are many application scenarios of multi-band coexistence, such as coexistence of GPS (Global positioning system) and TDD (Time Division duplex) bands. For example, there is a situation that GPS and LTE work together in the processes of location-based positioning sharing and Voice LTE communication, wherein, when TX in TDD band works, noise falling to GPS frequency band is generated, and at this time, if the suppression and antenna isolation on TX channel do not meet the requirement (the noise received by GPS antenna must be less than-174 dbm/Hz, otherwise, the GPS performance will be degraded), the TX noise will be received by GPS antenna, which in turn causes the degradation of GPS CN0 value (i.e. carrier-to-noise ratio), so that when GPS and TDD band work simultaneously, interference is easily generated, which in turn causes the phenomenon of GPS positioning inaccuracy or satellite loss, which seriously affects user experience.
In order to solve the above problems, hardware or software solutions are generally adopted in the prior art. In terms of hardware, the noise falling on the GPS frequency band generated during TX operation is suppressed by adding a BPF (bandpass Filter) to a hardware path of the TDD frequency band, adding an LC resonant network, and increasing isolation between the main antenna and the GPS antenna. In many cases, the output GPS noise can cause the antenna isolation > -174dbm/Hz, so that the sensitivity of the GPS CN0 is attenuated by more than 3db at the maximum power transmission, and the user experience is further influenced. The BLANKING mechanism is typically employed in software (i.e., when the TX in TDD band is active, the GPS receiver is turned off, and vice versa): the BLANKING mechanism is turned on when the TDD band is detected to be working together with GPS. This approach would theoretically cause some reduction in GPS CN0, e.g., turning on the BLANKING mechanism when LTE B39 coexists with GPS would cause GPS CN0 to fall by 2.2db (typically: TX operates 2ms every 5 ms); in addition, in practical use, the TDD band is not always in a maximum power transmission state, and when the transmission power of the TDD band is smaller than a certain value, there is almost no interference to the GPS, and turning on the BLANKING mechanism will cause the performance of the GPS to be more seriously degraded.
Therefore, the prior art does not well solve the problem of interference of the TDD band to the GPS when the TDD band and the GPS coexist.

An access terminal may be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless local loop) station, a PDA (personal digital Assistant), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G Network, or a terminal device in a future evolved PLMN (Public Land Mobile Network) Network.
Fig. 1 is a flow chart of an interference handling method in an embodiment of the present invention. The method of fig. 1 may include:
s102, when it is monitored that the mobile terminal simultaneously works in the first frequency band and the second frequency band, determining a first working state of the mobile terminal in the second frequency band according to the current position information of the mobile terminal and/or the carrier-to-noise ratio of the second frequency band.
The first working state comprises a closing state or an operating state; the first frequency band and the second frequency band have different center frequencies. Carrier-to-noise ratio is a standard measurement scale used to indicate the carrier-to-carrier noise relationship. A high carrier to noise ratio may provide better network reception rates, better network communication quality, and better network reliability.
And S104, determining whether to adjust the current working state of the mobile terminal in the second frequency band according to the first working state of the mobile terminal in the second frequency band.
If the first working state of the mobile terminal in the second frequency band is the closed state, adjusting the current working state of the mobile terminal in the second frequency band to be the closed state; if the first working state of the mobile terminal in the second frequency band is the running state, the current working state of the mobile terminal in the second frequency band does not need to be adjusted.
In the embodiment of the invention, when the mobile terminal is monitored to simultaneously work in the first frequency band and the second frequency band, the working state of the mobile terminal in the second frequency band can be determined according to the current position information of the mobile terminal and/or the carrier-to-noise ratio of the second frequency band, and whether the current working state of the mobile terminal in the second frequency band is adjusted or not is determined according to the determined working state of the mobile terminal in the second frequency band. Therefore, when the technical scheme is used for solving the coexistence problem of the first frequency band and the second frequency band, the mobile terminal is not simply directly stopped to work in the second frequency band, but whether the working state of the mobile terminal in the second frequency band is adjusted or not is determined according to various factors (namely the current position information of the mobile terminal and/or the carrier-to-noise ratio of the second frequency band), so that the influence on the performance of the second frequency band when the first frequency band and the second frequency band coexist can be reduced to the maximum extent, the problem that the GPS is inaccurate in positioning or is lost due to the fact that the TDD frequency band interferes with the GPS is solved, and the influence on user experience caused by the fact that the mobile terminal directly stops working in the second frequency band is avoided.
The method of the embodiments of the present invention will be further described with reference to specific embodiments.
In one embodiment, the first operating state of the mobile terminal in the second frequency band may be determined according to the following steps a 1-A3:
and step A1, positioning the current position information of the mobile terminal.
Wherein the current position information includes at least one of longitude information, latitude information, and altitude information.
Step a2, obtaining a corresponding relationship between the pre-stored location information of the mobile terminal and the operating state of the mobile terminal in the second frequency band, and determining whether the corresponding relationship includes the first location information matched with the current location information.
The first position information comprises position information in a spherical area which takes a position corresponding to the current position information as a center and takes a preset threshold value as a radius. The matching of the first position information and the current position information means that the first position information is located in a spherical area with the current position information as a center and a preset threshold as a radius.
Step A3, if the corresponding relation includes first position information matched with the current position information, determining that the working state corresponding to the first position information is a first working state; and if the corresponding relation does not contain the first position information matched with the current position information, determining a first working state of the mobile terminal in the second frequency band according to the carrier-to-noise ratio of the second frequency band.
Take the example that the location information includes latitude and longitude information and altitude information. For example, the current position information is (X)0，Y0，Z0) Wherein X is0As longitude information, Y0As latitude information, Z0Is altitude information. Then, at the position (X)0，Y0，Z0) The position information in the spherical area with the preset threshold r as the radius is matched with each other. Fig. 2 shows a spherical area in which the pieces of position information that match each other are located, and all pieces of position information in the spherical area match each other.
In this embodiment, if the current location information matches the first location information, the operating state corresponding to the first location information is determined as the first operating state of the mobile terminal in the second frequency band. That is to say, the first operating states of the mobile terminals in the second frequency band corresponding to the position information in the same area are determined to be the same through real-time position location tracking, so that the first operating states of the mobile terminals in the second frequency band are prevented from being repeatedly determined at the position in the same area, and the power consumption of the mobile terminals is greatly saved.
In an embodiment, when determining the first operating state of the mobile terminal in the second frequency band according to the carrier-to-noise ratio in the second frequency band, the following steps B1-B4 may be specifically included:
and step B1, determining the first carrier-to-noise ratio of the second frequency band when the mobile terminal simultaneously works in the first frequency band and the second frequency band.
And step B2, determining a second carrier-to-noise ratio of the second frequency band when the mobile terminal works in the first frequency band and does not work in the second frequency band.
The execution order of step B1 and step B2 is not limited. That is, step B1 may be executed first, and then step B2 may be executed according to the sequence described in the present embodiment; step B2 may be performed first, followed by step B1.
Step B3, comparing the first carrier to noise ratio with the second carrier to noise ratio to determine whether the first carrier to noise ratio is smaller than the second carrier to noise ratio.
Step B4, if the first carrier-to-noise ratio is smaller than the second carrier-to-noise ratio, determining that the first working state of the mobile terminal in the second frequency band is a closed state; and if the first carrier-to-noise ratio is larger than or equal to the second carrier-to-noise ratio, determining that the first working state of the mobile terminal in the second frequency band is a running state.
In this embodiment, the carrier-to-noise ratio of the second frequency band when the mobile terminal is in different operating states is compared, and it is determined that the first operating state of the mobile terminal in the second frequency band is the off state or the operating state according to the comparison result, rather than stopping the mobile terminal from operating in the second frequency band in any environment, so that the influence on the performance of the second frequency band when the first frequency band and the second frequency band coexist can be reduced to the greatest extent, and the problem that the user experience is influenced by directly stopping the mobile terminal from operating in the second frequency band is avoided.
In one embodiment, after determining the first working state of the mobile terminal in the second frequency band, the current position information of the mobile terminal can be recorded, and the second position information of the mobile terminal is positioned after a preset time length; and judging whether the second position information is the same as the recorded current position information. If the second position information is different from the recorded current position information, further judging whether the second position information is matched with the current position information; and if the second position information is not matched with the current position information, determining a first working state of the mobile terminal in the second frequency band according to the second position information and/or the carrier-to-noise ratio of the second frequency band. The second position information is matched with the current position information, namely the second position information is located in a spherical area which takes the current position information as a center and takes a preset threshold value as a radius. And a spherical area with the current position information as a center and a preset threshold value as a radius. Reference is made to fig. 2 above, and the description is omitted here. It should be understood that the second location information of the mobile terminal is located after the preset duration, that is, the location information of the mobile terminal is located after every preset duration, so as to determine the first operating state of the mobile terminal in the second frequency band.
That is, if the second location information is the same as the recorded current location information or the second location information is matched with the recorded current location information, the working state of the mobile terminal in the second frequency band does not need to be changed; and if the second position information is different from the recorded current position information and the second position information is not matched with the recorded current position information, re-determining the working state of the mobile terminal in the second frequency band. The method for re-determining the operating state of the mobile terminal in the second frequency band is the same as that in the above embodiment, and is not repeated here.
In one embodiment, whether the location information of the mobile terminal changes may be monitored according to a preset frequency.
In this embodiment, the working state of the mobile terminal in the second frequency band is determined in real time by monitoring whether the current location information changes, so that the influence on the performance of the second frequency band can be minimized by the working state of the mobile terminal in the second frequency band, and thus, the working state of the mobile terminal in each frequency band is adjusted in real time when the first frequency band and the second frequency band coexist.
In one embodiment, the first frequency band is a Time Division Duplex (TDD) frequency band, and the second frequency band is a Global Positioning System (GPS) frequency band.
The interference processing method provided by the above embodiment is described as an embodiment.
Fig. 3 is a flow chart of an interference handling method in an embodiment of the invention. In this embodiment, the coexisting frequency bands include a GPS frequency band and a TDD frequency band, where the TDD frequency band refers to a GSM (Global System for mobile communication) frequency band (850/EGSM/DCS/PCS), an LTE-TDD (Time Division long Term Evolution) frequency band (B34/B39), and a TDSCDMA (Time Division-Synchronous Code Division Multiple Access) frequency band (B34/B39). As shown in fig. 3, the interference processing method includes the following steps:
s301, monitoring that the mobile terminal works in the GPS frequency band and the TDD frequency band simultaneously.
S302, recording the current position information of the positioned mobile terminal, and acquiring the corresponding relation between the prestored position information of the mobile terminal and the working state of the mobile terminal in the GPS frequency band.
The current position information includes longitude information, latitude information and altitude information.
S303, judging whether the corresponding relation contains first position information matched with the current position information; if not, executing S304; if yes, go to S309.
The first position information comprises position information in a spherical area which takes a position corresponding to the current position information as a center and takes a preset threshold value as a radius.
S304, determining a first carrier-to-noise ratio of the GPS frequency band under the condition that the mobile terminal works in the GPS frequency band and the TDD frequency band simultaneously.
S305, determining a second carrier-to-noise ratio of the GPS frequency band under the condition that the mobile terminal works in the TDD frequency band but does not work in the GPS frequency band.
S306, comparing the first carrier-to-noise ratio with the second carrier-to-noise ratio to judge whether the first carrier-to-noise ratio is smaller than the second carrier-to-noise ratio; if yes, go to S307; if not, go to S308.
S307, determining that the first working state of the mobile terminal in the GPS frequency band is a closed state, and turning on the GPS. Execution continues with S310.
S308, determining that the first working state of the mobile terminal in the GPS frequency band is a running state, and not adjusting the working state of the mobile terminal in the GPS frequency band. Execution continues with S310.
S309, determining that the working state corresponding to the first position information is the first working state of the mobile terminal in the GPS frequency band.
S310, after the preset time length, positioning second position information of the mobile terminal, and judging whether the second position information is the same as or matched with the recorded current position information; if not, returning to S302; if yes, go to S311.
The second position information is matched with the current position information, namely the second position information is located in a spherical area which takes the current position information as a center and takes a preset threshold value as a radius. The spherical area with the current position information as the center and the preset threshold as the radius can be referred to the above fig. 2, and is not described herein again.
S311, the working state of the current mobile terminal in the GPS frequency band is not adjusted. Returning to the step S310, continuing to position the new location information of the mobile terminal after the preset duration, and further determining whether to adjust the working state of the mobile terminal in the second frequency band according to the positioned new location information.
It can be seen that, when the technical solution of this embodiment solves the coexistence problem of the GPS and TDD frequency bands, instead of simply directly stopping the mobile terminal from operating in the GPS frequency band, whether to adjust the operating state of the mobile terminal in the GPS frequency band is determined according to various factors (i.e., the current location information of the mobile terminal and/or the carrier-to-noise ratio of the GPS frequency band), so that the influence on the performance of the GPS frequency band when the GPS and TDD frequency bands coexist can be reduced to the maximum extent, and the problem that the user experience is influenced by directly stopping the mobile terminal from operating in the GPS frequency band is avoided. In addition, the first working state of the mobile terminal in the GPS frequency band corresponding to the position information in the same area is determined to be the same through real-time position positioning and tracking, so that the first working state of the mobile terminal in the GPS frequency band is prevented from being repeatedly determined at the position in the same area, and the power consumption of the mobile terminal is greatly saved.
