[0002] Currently, in the related art, inter-system adjacent frequency interference usually adopts limiting device transmitter indicators to achieve the purpose of interference protection for adjacent frequency system receivers.

[0025] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative effort should fall into the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", and the like in the description and claims of the present application and the above-described accompanying drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product, or device.

[0027] At present, in the related art, in order to ensure the link budget of satellite communication, the in-band transmission power of the satellite terminal is usually high, the antenna gain is large, and the antenna usually has directivity, and there is a pointing process during service use, so that the interference caused by the satellite terminal has obvious directivity characteristics. Under normal user usage habits, the mobility of the terminal makes the probability of terminal-to-terminal interference low, which is convenient to solve. However, effective measures need to be taken to eliminate the interference of the satellite terminal to the base station.

[0028] In order to solve this problem, the related solutions in the embodiments of the present application are provided, which will be described in detail below.

[0029] According to the embodiments of the present application, a method embodiment of a position information adjustment method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in a different order from that shown herein.

[0030] Figure 1 is a flowchart of a position information adjustment method according to the embodiments of the present application, as shown in Figure 1 The method comprises the following steps:

[0031] Step S102, acquiring the position information of the terminal device.

[0032] In the technical solution provided in step S102, the position information of the terminal device can be acquired. The terminal device can be a satellite communication terminal. The position information can include at least terminal position information and a satellite azimuth angle information.

[0033] Optionally, when the satellite communication terminal is in the process of accessing the network, the satellite communication terminal needs to report the terminal position information and the satellite azimuth angle information to the satellite network side. The position information of the satellite communication terminal can be acquired.

[0034] In step S104, the position information is compared with the calibration information to obtain a comparison result. The calibration information is used to represent the interference avoidance level calibrated for different cellular network coverage areas.

[0035] In the technical solution provided in step S104, after the position information of the terminal device is acquired, the position information is compared with the calibration information to obtain a comparison result. The calibration information can be used to represent the interference avoidance level calibrated for different cellular network coverage areas, and the calibration information can also be referred to as preset interference region calibration information.

[0036] It should be noted that according to the electronic map, the satellite network side can calibrate the interference avoidance level for different regions according to the interference regulation requirements. For example, a 0-level region can be a non-coordination requirement region, a 1-level region can be a prohibited emission region, and a 2-level region can be a ground cellular network coordination region. This embodiment only calibrates the cellular network coverage area that has potential interference to a specific frequency band.

[0037] Optionally, after the position information of the terminal device is acquired, the satellite network side can compare the position information of the terminal with the preset interference region calibration information to obtain a comparison result.

[0038] In step S106, in response to the comparison result that the position information is in a first-level region corresponding to the interference avoidance level, interference information for interfering with the terminal device is determined.

[0039] In the scheme provided in step S106, after the position information is compared with the calibration information to obtain a comparison result, when the obtained comparison result is that the position information is in a first-level region corresponding to the interference avoidance level, in response to the comparison result that the position information is in the first-level region corresponding to the interference avoidance level, the interference information for interfering with the terminal device can be determined. The first-level region can be a ground cellular network coordination region, i.e., a 2-level region. The interference information can be information estimated by the terminal according to the blocking interference and the spurious interference to the interference of the cellular base station, and the interference information can also be referred to as an estimation result.

[0040] Optionally, after comparing the position information with the calibration information to obtain a comparison result, when the comparison result is that the position of the terminal falls within the second level region calibrated, the interference information for interfering the terminal device can be determined.

[0041] In step S108, the position information of the terminal device is adjusted based on the interference information.

[0042] In the technical solution provided in step S108, after the interference information for interfering the terminal device is determined, the position information of the terminal device can be adjusted based on the interference information.

[0043] Optionally, after the interference information for interfering the terminal device is determined, the terminal can attempt to instruct the user to adjust the position of the terminal according to the interference information, i.e., the estimation result, so as to achieve the purpose of enabling the terminal after the position adjustment to meet the interference avoidance condition.

[0044] In the embodiments of the present application, the position information of the terminal device is obtained; the position information is compared with calibration information to obtain a comparison result, wherein the calibration information is used to represent the interference avoidance levels calibrated for different cellular network coverage regions; in response to the comparison result being that the position information is within a first level region corresponding to the interference avoidance levels, interference information for interfering the terminal device is determined; and the position information of the terminal device is adjusted based on the interference information. That is, the position information of the terminal device obtained is compared with the calibration information to obtain a comparison result, when the comparison result is that the position information is within a first level region corresponding to the interference avoidance levels, the interference information for interfering the terminal device can be determined, and further based on the determined interference information, the position information of the terminal device can be adjusted, thereby achieving the technical effect of effectively adjusting the position information of the terminal device, and further solving the technical problem of being unable to effectively adjust the position information of the terminal device.

[0045] The above method of the embodiment will be further introduced below.

[0046] In some embodiments of the present application, in step S106, in response to the comparison result being that the position information is within a first level region corresponding to the interference avoidance levels, the interference information for interfering the terminal device is determined, comprising: in response to the comparison result being that the position information is within a first level region corresponding to the interference avoidance levels, obtaining the azimuth information between the terminal device and the satellite; and based on the azimuth information, determining the interference information for interfering the terminal device.

[0047] In this embodiment, after the comparison between the position information and the calibration information is performed, and a comparison result is obtained, when the comparison result is that the position information is in the first level region corresponding to the interference avoidance level, the azimuth angle information between the terminal device and the satellite can be obtained. Based on the obtained azimuth angle information, the interference information for interfering the terminal device can be determined. The azimuth angle information can be the satellite-to-terminal azimuth angle information.

[0048] Optionally, when the position of the terminal falls into the calibrated second level region, the satellite network side can obtain the satellite-to-terminal azimuth angle information of the terminal. Based on the obtained satellite-to-terminal azimuth angle information, the interference information for interfering the terminal device can be determined.

[0049] In some embodiments of the present application, based on the azimuth angle information, the interference information for interfering the terminal device is determined, including: based on the azimuth angle information, determining whether there is a cellular base station in the first level region; in response to the existence of the cellular base station in the first level region, determining the current position information of the cellular base station; and based on the current position information of the cellular base station, determining the interference information for interfering the terminal device.

[0050] In this embodiment, after the azimuth angle information of the terminal device is obtained, based on the obtained azimuth angle information, it can be determined whether there is a cellular base station in the first level region. When there is a cellular base station in the first level region, in response to the existence of the cellular base station in the first level region, the current position information of the cellular base station can be determined. Further based on the determined current position information of the cellular base station, the interference information for interfering the terminal device can be determined. The current position information can at least include the position information and the sector antenna configuration information of the cellular base station.

[0051] Optionally, after the satellite network side obtains the satellite-to-terminal azimuth angle information of the terminal, it can be determined whether there is a cellular base station within the azimuth normal of the satellite-to-terminal azimuth angle + / - X°. When it is determined that a cellular base station falls within the azimuth normal + / - X°, the satellite network side can issue the position (such as longitude and latitude) of such base station, and the sector antenna configuration (such as the sector antenna pointing azimuth angle) and other information, so that the current position information of the cellular base station can be determined. After the current position information of the cellular base station is determined, the terminal can estimate the interference to the cellular base station according to the interference avoidance condition, that is, determine the interference information.

[0052] In some embodiments of the present application, the method further includes: in response to the non-existence of the cellular base station in the first level region, allowing the terminal device to work in the satellite mode.

[0053] In this embodiment, after the terminal device's azimuth information is acquired, whether there is a cellular base station in the first level region can be determined based on the acquired azimuth information. When there is no cellular base station in the first level region, the terminal device can be allowed to work in the satellite mode in response to the fact that there is no cellular base station in the first level region.

[0054] Optionally, after the satellite network side acquires the terminal's azimuth information, it can be determined whether there is a cellular base station within the azimuth normal of the azimuth information + / - X°. When it is determined that no cellular base station falls within the azimuth normal + / - X°, the satellite network side instructs the terminal to normally work in the satellite mode.

[0055] In some embodiments of the present application, based on the interference information, the position information of the terminal device is adjusted, including: in response to the interference information not satisfying the interference avoidance condition, adjusting the position information of the terminal device based on the interference information.

[0056] In this embodiment, after the interference information for interfering the terminal device is determined based on the current position information of the cellular base station, it can be determined whether the interference information satisfies the interference avoidance condition. When the interference information does not satisfy the interference avoidance condition, the position information of the terminal device can be adjusted based on the determined interference information in response to the fact that the interference condition does not satisfy the interference avoidance condition.

[0057] Optionally, after the interference information for interfering the terminal device is determined, it can be determined whether the interference information satisfies the interference avoidance condition by the following formula:

[0058]

[0059]

[0060] wherein formula (1) can be used to represent the blocking interference estimation, formula (2) can be used to represent the stray interference estimation, P tx may be used to represent the terminal transmit power, G tx may be used to represent the terminal transmit antenna gain in the interference direction, G rx may be used to represent the base station receive antenna gain in the interfered direction, PLmay be used to represent the path loss, I max_Blocking and I max_Emission may be used to represent the tolerable interference threshold, may be used to represent the angle between the terminal antenna pointing and the line connecting the terminal and the base station, and θmay be used to represent the angle between the base station sector antenna pointing and the terminal interference direction. When the determined interference information does not satisfy the above interference avoidance condition, i.e., does not satisfy the determination condition, the terminal attempts to instruct the user to adjust the terminal position to satisfy the above interference avoidance condition according to the determined interference information, i.e., according to the estimation result.

[0061] In some embodiments of the present application, the method further comprises: in response to the interference condition satisfying the interference avoidance condition, allowing the terminal device to work in the satellite mode.

[0062] In this embodiment, after determining the interference information for the interfering terminal device based on the current location information of the cellular base station, it can be determined whether the interference information satisfies the interference avoidance condition. When the interference information satisfies the interference avoidance condition, in response to the interference condition satisfying the interference avoidance condition, the terminal device can be allowed to work in the satellite mode.

[0063] Optionally, when the determined interference information satisfies the above interference avoidance condition, i.e., satisfies the determination condition, the terminal can normally work in the satellite mode.

[0064] In some embodiments of the present application, after step S104, the method further comprises: in response to the comparison result being that the location information is in the second-level region corresponding to the interference avoidance level, prohibiting the terminal device from working in the satellite mode.

[0065] In this embodiment, after comparing the location information with the calibration information to obtain the comparison result, when the obtained comparison result is that the location information is in the second-level region corresponding to the interference avoidance level, in response to the comparison result being that the location information is in the second-level region corresponding to the interference avoidance level, the terminal device can be prohibited from working in the satellite mode. The second-level region can be a prohibited emission region, i.e., a level 1 region.

[0066] Optionally, after comparing the location information with the calibration information to obtain the comparison result, when the obtained comparison result is that the location of the terminal falls within the calibrated level 1 region, the satellite network side instructs the terminal to be prohibited from working in the satellite mode within the region.

[0067] In some embodiments of the present application, after step S104, the method further comprises: in response to the comparison result being that the location information is in the third-level region corresponding to the interference avoidance level, allowing the terminal device to work in the satellite mode.

[0068] In this embodiment, after comparing the location information with the calibration information to obtain the comparison result, when the obtained comparison result is that the location information is in the third-level region corresponding to the interference avoidance level, in response to the comparison result being that the location information is in the third-level region corresponding to the interference avoidance level, the terminal device can be allowed to work in the satellite mode. The third-level region can be a no-coordination-required region, i.e., a level 0 region.

[0069] Optionally, after comparing the position information with the calibration information to obtain a comparison result, when the comparison result is that the position of the terminal falls into the 0th level region calibrated, the terminal can work in the satellite mode.

[0070] The embodiment obtains position information of a terminal device; compares the position information with calibration information to obtain a comparison result, wherein the calibration information is used to represent interference avoidance levels calibrated for different cellular network coverage regions; in response to the comparison result being that the position information is in a first level region corresponding to the interference avoidance levels, determines interference information used to interfere with the terminal device; and adjusts the position information of the terminal device based on the interference information. That is, the embodiment compares the obtained position information of the terminal device with the calibration information to obtain a comparison result, when the comparison result is that the position information is in a first level region corresponding to the interference avoidance levels, the interference information used to interfere with the terminal device can be determined, and further based on the determined interference information, the position information of the terminal device can be adjusted, thereby achieving the technical effect of effectively adjusting the position information of the terminal device, and further solving the technical problem of being unable to effectively adjust the position information of the terminal device.

[0071] The technical solutions of the embodiments of the application will be described below in conjunction with preferred embodiments.

[0072] Due to the scarcity of spectrum resources, the spectrum resources used by the satellite directly connected to the mobile phone and the spectrum of the ground cellular network generally appear adjacent frequency, especially the adjacent frequency interference problem between the satellite and the ground service system. Figure 2 is a schematic diagram of frequency bands used by different ground systems according to the embodiments of the application, as shown in Figure 2 The frequency band used by the first ground system, i.e. the China Telecom ground system, is 1920-1940 / 2110-2130 megahertz (MHz), the frequency band used by the second ground system, i.e. the China Unicom ground system, is 1940-1965 / 2130-2155 MHz, the frequency band used by the railway 5G-R is 1965-1980 / 2155-2170 MHz, the frequency band used by the third ground system, i.e. the China Telecom ground system, is 1980-2010 / 2170-2200 MHz, and the frequency band used by the fourth system, i.e. the China Mobile system, is 2010-2025 MHz.

[0073] At present, the 1980-2010 / 2170-2200MHz frequency band used by Tianhong No. 1 system is the global satellite mobile service (Mobile Satellite Service, abbreviated as MSS) frequency band. In this frequency band and the adjacent continuous frequency band, mobile services (Mobile Services, abbreviated as MS) are also the main service division. According to the frequency allocation, the lower end of the satellite terminal ground-to-space frequency band is adjacent to a plurality of ground systems, including China Unicom international roaming (International Mobile Telecommunication, abbreviated as IMT) ground system and railway 5th generation radio (5th Generation Radio, abbreviated as 5G-R) system, and the upper end is adjacent to China Mobile IMT ground system. There are two types of interference scenarios of satellite terminal to ground network base station and satellite terminal to ground network terminal.

[0074] Interference between systems usually uses to limit the transmitter index of the device to achieve the purpose of interference protection of the receiver of the adjacent frequency system. However, a trade-off needs to be made between spectrum use efficiency and terminal radio frequency implementation or cost. According to the 3GPP related protocols, such as TS36.101 and TS36.104, the in-band transmit power level of the satellite terminal in the adjacent frequency scenario is calculated according to the general protection limit value of the base station anti-blocking, and the satellite terminal will not be able to establish an effective satellite communication link. In order to achieve the requirement of out-of-band coexistence protection index, the terminal radio frequency performance requirement is extremely high, which greatly increases the cost and is not conducive to the development of the industry. At the same time, by setting a protection band, the implementation difficulty of the device can be reduced, but it is not conducive to the effective use of spectrum resources.

[0075] In order to ensure the link budget of satellite communication, the in-band transmit power of satellite terminal is usually high, and the antenna gain is large, and the antenna usually has directivity, and there is a process of pointing to the star during use. Therefore, the interference caused by the satellite terminal has obvious directivity characteristics. Under normal user habits, the mobility of the terminal makes the probability of terminal-to-terminal interference low, which is easy to solve. However, effective measures need to be taken to eliminate the interference of satellite terminal to base station. Due to the scarcity of medium and low frequency spectrum resources, the frequency band used by satellite terminal supporting mobile phone direct satellite application is generally adjacent to the interference of ground service network, especially the interference scenario of satellite terminal to ground network base station needs to use effective interference avoidance measures.

[0076] To solve the problem of adjacent frequency interference of satellite terminals to ground network, the embodiment provides an adjacent frequency interference coordination mechanism based on azimuth information, in which an electronic fence is preset for a specific geographic area and an interference coordination level is calibrated in combination with an electronic map on the satellite network side, the terminal reports necessary azimuth information in the network access process, the network side issues a satellite mode disable instruction to the terminal or issues information of interfered base stations and their azimuths to the user for interference estimation based on the terminal position and azimuth information, and the user is instructed to adjust the position to avoid interference to the ground station based on the estimation result.

[0077] Figure 3 is a schematic diagram of calibrating an interference avoidance level according to the embodiment of the application, as shown in the embodiment, the satellite network side can calibrate interference avoidance levels for different areas according to interference monitoring requirements based on the electronic map, for example, a 0-level area can be a non-coordination requirement area, a 1-level area can be a prohibited emission area, and a 2-level area can be a ground cellular network coordination area. The embodiment only calibrates the cellular network coverage area that has potential interference to a specific frequency band. When the satellite communication terminal accesses the network, the terminal needs to report terminal position information and azimuth angle information to the satellite network side. Figure 3

[0078] is a flowchart of an interference coordination method based on position and antenna azimuth information according to the embodiment of the application, as shown in the embodiment, the flowchart of the interference coordination method based on position and antenna azimuth information can include the following steps: Figure 4 Figure 4 Step S401, access the network by the terminal.

[0079] In the above step S401, the terminal accesses the network initially after being powered on.

[0080] In the above step S402, when the satellite communication terminal accesses the network, the satellite communication terminal needs to report terminal capability information to the satellite network side, which at least includes terminal position information and azimuth angle information.

[0081] Step S402, report the position information.

[0082] In the above step S402, when the satellite communication terminal accesses the network, the satellite communication terminal needs to report terminal capability information to the satellite network side, which at least includes terminal position information and azimuth angle information.

[0083] Step S403, determine the coordination level based on the terminal position information.

[0084] In the above step S403, the satellite network side compares the position information of the terminal with the preset interference area calibration information, that is, the network side determines the coordination level X of the terminal according to the terminal position.

[0085] Step S404, determine whether there is an interfered base station based on the terminal azimuth angle information.

[0086] ​In step S404, when the coordination level X=2, it means that the terminal needs to coordinate with the cellular network, then the network side further determines whether there is a potential interfering base station according to the terminal azimuth angle. When there is a potential interfering base station, go to step S405, otherwise, go to step S408.

[0087] In step S405, the terminal is informed of the base station position information and the antenna azimuth angle information.

[0088] In step S405, when there is a potential interfering base station, the network side informs the terminal of the base station position and the antenna azimuth angle.

[0089] In step S406, it is estimated whether there is interference.

[0090] In step S406, the terminal estimates the interference based on the received base station position and the antenna azimuth angle, and determines whether there is interference. When there is interference, go to step S407, otherwise, go to step S408.

[0091] In step S407, the terminal position is adjusted.

[0092] In step S407, when there is interference, the terminal instructs the user to adjust the position according to the estimation result to meet the avoidance condition.

[0093] In step S408, the terminal normally accesses the satellite network.

[0094] In step S408, when the terminal position falls into the marked 0-level area, i.e. the coordination level X=0, it means that there is no coordination requirement, then the terminal can work in the satellite mode and normally access the satellite network.

[0095] In step S409, the satellite mode is disabled.

[0096] In step S408, when the terminal position falls into the marked 1-level area, i.e. the coordination level X=1, then the satellite network side instructs the terminal to disable the satellite mode in this area, i.e. disable the satellite mode.

[0097] Optionally, when the satellite communication terminal is in the process of accessing the network, the satellite communication terminal needs to report terminal capability information to the satellite network side, which at least includes terminal position information and azimuth angle information. The satellite network side compares the terminal position information with the preset interference region demarcation information. When the terminal position falls into the demarcated 0-level region, the terminal can work in the satellite mode. When the terminal position falls into the demarcated 1-level region, the satellite network side instructs the terminal to be prohibited from working in the satellite mode in the region. When the terminal position falls into the demarcated 2-level region, the satellite network side determines whether there is a cellular base station within the range of + / - X° of the azimuth normal according to the terminal azimuth angle. When it is determined that there is no cellular base station falling into the range of + / - X° of the azimuth normal, the satellite network side instructs the terminal to normally work in the satellite mode. When it is determined that there is a cellular base station falling into the range of + / - X° of the azimuth normal, the satellite network side can issue information such as the position (for example, longitude and latitude) of the base station and the sector antenna configuration (for example, the sector antenna pointing azimuth angle).

[0098] Figure 5 is a schematic diagram for adjusting the terminal position to avoid interference based on the interference estimation result according to the embodiment of the present application, as shown in Figure 5 The terminal can estimate the interference of the cellular base station according to the interference avoidance condition, and whether the interference information satisfies the interference avoidance condition can be determined by the following formula:

[0099]

[0100]

[0101] wherein formula (1) can be used to represent the blocking interference estimation, formula (2) can be used to represent the spurious interference estimation, P tx may be used to represent the terminal transmit power, G tx may be used to represent the transmit antenna gain of the terminal in the interference direction, G rx may be used to represent the receive antenna gain of the base station in the interfered direction, PLmay be used to represent the path loss, I max_Blocking and I max_Emission may be used to represent the tolerable interference threshold, may be used to represent the angle between the terminal antenna pointing and the line connecting the terminal and the base station, and θmay be used to represent the angle between the base station sector antenna pointing and the terminal interference direction. When the estimation result satisfies the above interference avoidance condition, that is, satisfies the determination condition, the terminal can normally work in the satellite mode. When the estimation result does not satisfy the above interference avoidance condition, that is, does not satisfy the determination condition, the terminal tries to instruct the user to adjust the terminal position to satisfy the above interference avoidance condition according to the determined estimation result.

[0102] The 2GHz MSS frequency band (1980-2010 / 2170-2200MHz) in the embodiment is a dedicated frequency band for high-orbit satellite systems. The lower end of the frequency band is in close frequency relationship with the 5th Generation New Radio (5G NR) 2GHz ground cellular network, and the upper end of the frequency band is also in close frequency relationship with the ground cellular network. There is a risk that the MSS satellite terminal will interfere with the 5G-R system base station along the railway line and the ground cellular base station. The interference of the 5G-R system involves railway safety issues and needs to avoid the emission of interference signals as much as possible. The embodiment effectively avoids the interference of the high-security area through the interaction of station location information, and uses the antenna directivity characteristics of the interfering station and the interfered station to estimate and avoid interference through network interaction of necessary information, which can effectively solve such interference problems.

[0103] The embodiment realizes interference avoidance of the satellite terminal to the ground fixed position base station based on network and terminal position and orientation information interaction. The network side combines the electronic map to calibrate the interference coordination level of a specific geographic area for interference coordination, uses the terminal antenna directivity characteristics to realize interference estimation and determination of the satellite terminal to the cellular base station, and guides the terminal to adjust the position based on the interference estimation result, thereby achieving the effect of avoiding interference.
