Broadcast Channel (BCH): and transmitting the information channel of the information in a broadcasting mode.

At present, when a user uses a mobile phone and a functional module and a cellular communication module are used together, the mobile phone is easily interfered, and the service sensitivity of the cellular communication module is influenced. Specifically, a Liquid Crystal Display Module (LCM) is a man-machine interaction system on a mobile phone, and a Crystal Oscillator (OSC) is integrated therein, and when a function Module works, the Crystal Oscillator generates an operating frequency, and when the operating frequency or a frequency division and/or a frequency multiplication of the operating frequency is within a communication frequency range of a cellular communication Module, the OSC Module affects service sensitivity of the cellular communication Module, and generates interference to the mobile phone, and a Module interference schematic diagram is shown in fig. 1, which may affect user experience.

For example, there is a certain deviation between channels interfered by different products, as shown in fig. 2a and fig. 2b, fig. 2a is a schematic diagram of OSC interference of GSM1900 provided in the embodiment of the present application, and fig. 2b is a schematic diagram of OSC interference of GSM1800 provided in the embodiment of the present application. Taking GSM1900 as an example, in the figure, the horizontal axis number represents the channel number included in GSM1900, the vertical axis represents the interference degree, the horizontal line segment (i) represents the reference line, the line other than the horizontal line segment (i) represents the actual test value of OSC for the bright screen interference of GSM1900, and when the actual test value is higher than the reference line, it indicates that OSC generates the bright screen interference for GSM1900 under the corresponding channel. As shown in fig. 2a, the OSC frequency of a certain product is 89.75M, and the number of the OSC to the interference channel of GSM1900 is 725 to 743, where a table look-up shows that the frequency corresponding to the middle channel with the largest interference to GSM1900 is 1974.6M, i.e. the bright-screen interference frequency of GSM1900 is 22 integer multiples of the OSC frequency. At this time, the OSC module of the product may generate a great interference to its communication module, which affects the user experience. Similarly, as shown in fig. 2b, the numbers of the OSC to the interference channel of GSM1800 are 512 to 530, 554 to 558, where a look-up table indicates that the frequency corresponding to the middle channel with the largest interference to GSM1800 is 1795M, that is, the bright-screen interference frequency of GSM1800 is 20 integer multiples of the OSC frequency. At this time, the OSC module of the product may generate serious interference to GSM1800 and GSM1900, which may affect the user experience.

In order to solve the above problem, embodiments of the present application provide an interference control method and a related apparatus, where the method is applied to an electronic device used by a user. The electronic equipment realizes frequency following of the OSC by adjusting the frequency deviation of the crystal oscillator OSC, and then jumps out an interference frequency point through frequency hopping, thereby avoiding interference on the cellular communication module. The present application may be applicable to specific application scenarios where the OSC causes interference to the cellular communication module, including but not limited to the application scenarios mentioned above.

An interference control method provided in the embodiments of the present application is described below.

Referring to fig. 4, fig. 4 is a flowchart illustrating an interference control method according to an embodiment of the present disclosure, where the interference control method is applied to the electronic device 30 shown in fig. 3, and as shown in fig. 4, the interference control method includes:

step 401, adjusting the frequency offset of the operating frequency of the crystal oscillator from the first frequency offset to a second frequency offset.

The frequency range of the first frequency of the crystal oscillator under the constraint of the second frequency offset is a first reference frequency subset, the frequency range of the first reference frequency subset after frequency division and/or frequency multiplication amplification is a first reference frequency set, the frequency range of the second frequency of the crystal oscillator under the constraint of the second frequency offset is a second reference frequency subset, the frequency range of the second reference frequency subset after frequency division and/or frequency multiplication amplification is a second reference frequency set, the intersection of the first reference frequency set and the second reference frequency set is an empty set, and the first frequency and the second frequency are preset reference frequency points for the frequency hopping of the crystal oscillator to avoid communication interference of the crystal oscillator on a cellular communication module.

The operating frequency of the OSC may be measured by the electronic device, for example, as shown in fig. 5, a waveform diagram a is a waveform diagram of the operating frequency of the OSC measured by the electronic device, and a waveform diagram B is a waveform diagram of the frequency doubled by the OSC measured by the electronic device, so that the operating frequency of the OSC can be obtained, and the frequency offset of the operating frequency is calculated based on the theoretical value of the OSC frequency.

It should be noted that, the operating frequency of the OSC after shipment from a factory of different products may be deviated, by way of example and not limitation, the theoretical value of the OSC frequency is 90.25M, and the accuracy error of the OSC frequency provided by a supplier is 1%, that is, as long as the range is 90.25M ± 1%, all the OSC frequencies belong to the normal operating frequency of the OSC. However, in an actual situation, a large error may exist, for example, the actual accuracy error of the OSC frequency is 5%, and at this time, if the frequency is still hopped according to the built-in algorithm with the accuracy error of 1% as the frequency hopping reference of the OSC frequency, the frequency point after hopping may return to the interference frequency point again, and interference may still occur.

Illustratively, the first frequency offset is 5%, the second frequency offset is 1%, the first frequency is 90.25M, the first reference frequency subset is 90.25M ± 1%, the first reference frequency set is (90.25M ± 1%)/N, N is a positive integer or N (90.25M ± 1%), N is a positive integer; the second frequency is a target frequency point of frequency hopping, and considering that the frequency hopping span of the OSC frequency cannot be too large, in this example, it is noted that the second frequency is 88.9M, the second reference frequency subset is 88.9M ± 1%, the second reference frequency set is (88.9M ± 1%)/M, M is a positive integer or M (88.9M ± 1%), and M is a positive integer, and since an intersection of the first reference frequency set and the second reference frequency set is an empty set, the situation that the frequency returns to the interference frequency point again after the second frequency of the target frequency point is hopped, and the effectiveness of frequency hopping is ensured.

In one possible example, the adjusting the frequency offset of the operating frequency of the crystal oscillator from the first frequency offset to the second frequency offset includes: acquiring the frequency of a mobile industry processor interface corresponding to a working component corresponding to the crystal oscillator; calculating to obtain a stepping value according to a first clock signal sequence corresponding to the frequency of the interface of the mobile industry processor and a second clock signal sequence corresponding to the working frequency of the crystal oscillator; and adjusting the first frequency offset to the second frequency offset according to the stepping value.

The method includes the steps that a Mobile Industry Processor Interface (MIPI) frequency is another working frequency in an LCM, errors between MIPI frequencies of different machines and standard MIPI frequencies calibrated after leaving a factory are found to be small through testing, the MIPI frequencies of the different machines are used as reference bases in the same product, the OSC frequency with a first frequency offset gradually reaches a standard range through adjustment of a stepping value, namely the first frequency offset is adjusted to be a second frequency offset, and therefore frequency following of the OSC is achieved.

Alternatively, the step value may be determined by: when each frame of picture is refreshed, a first clock signal sequence corresponding to the MIPI frequency and a second clock signal sequence corresponding to the OSC frequency are compared at a first command of the frame picture refreshing, the sampling counting comparison of signals is realized, the specific offset of the current OSC frequency offset reference standard of a product is obtained, and if the specific offset exceeds a standard range, a stepping value is obtained through calculation and the specific offset is adjusted through adjusting the stepping value. For example, please refer to fig. 6, fig. 6 is a schematic diagram of OSC frequency tracking provided in the embodiment of the present application, as shown in fig. 6, a signal sampling count comparison between a first clock signal sequence and a second clock signal sequence is performed at a first command of a current frame screen refresh, and a step value 1% is calculated if a frequency offset of a current OSC frequency of a product obtained through the sampling count comparison is 5% and exceeds a standard range of 0 to 1%, where the step value may be flexibly determined according to a specific product, and is not limited herein. By adjusting the step value by 1%, the frequency offset of the adjusted OSC frequency becomes 4%, and at this time, sampling counting comparison of signals is performed, and it is detected that the frequency offset is 4% and still larger than the standard range, so that the step value is continuously calculated and adjusted, where the step value obtained by recalculation here may be the step value by 1%, or other values, and may be flexibly determined according to different products. The above adjustment process is repeated until the frequency offset of the OSC frequency reaches the standard range.

In this example, the electronic device adjusts the frequency offset by adjusting the step value, and the frequency offset is automatically adjusted for multiple times until the frequency offset of the OSC frequency is changed from the first frequency offset to the second frequency offset, so that the OSC frequency is within the standard range, and frequency tracking is achieved. The method is ready for realizing the subsequent frequency hopping step, and ensures the effectiveness of frequency hopping.

In one possible example, after the obtaining the frequency of the mobile industry processor interface corresponding to the target working component, the method further includes: and modifying the screen unfolding mode of the screen unfolding image corresponding to the frequency of the mobile industry processor interface into screen unfolding towards two sides.

Wherein, the development screen mode of the exhibition screen image that MIPI frequency corresponds includes: and the screen is unfolded downwards and is unfolded towards two sides, wherein the default screen unfolding mode is the screen unfolding mode downwards, and the OSC frequency obtained in the screen unfolding mode is smaller as the OSC frequency is referred to the frequency of the MIPI as the center frequency. If the screen-expanding image corresponding to the MIPI frequency is changed into a screen-closing and expanding image, as shown in the screen-expanding image (i) in fig. 7, MIPI energy is all concentrated in the middle of the frequency points, which may cause serious interference to other components, and further affect the user experience. Therefore, on the basis of realizing OSC frequency hopping, the screen-spreading mode of the screen-spreading image corresponding to the MIPI frequency is modified to screen-spreading to both sides, as shown in fig. 7, so as to ensure that the obtained OSC frequency is accurate and avoid interference with other components.

As can be seen, in this example, the electronic device modifies the screen expansion mode of the screen expansion image corresponding to the MIPI frequency to screen expansion towards both sides, so that the accuracy of the OSC frequency for frequency tracking with the MIPI frequency as a reference is ensured, and interference to other components is avoided.

Step 402, when it is detected that at least one frequency in a first frequency set corresponding to a current first operating frequency of the crystal oscillator is within a current communication frequency range of the cellular communication module, generating a first frequency hopping instruction.

The first set of frequencies is used to characterize frequency division and/or frequency multiplication of the first operating frequency, where the first operating frequency belongs to the first reference frequency subset, that is, the first operating frequency is a result obtained by adjusting a frequency offset. It should be noted that, when the frequency offset is adjusted to realize OSC frequency tracking, the adjustment process is ended when the adjusted OSC frequency is detected to be in the first reference frequency subset, and the obtained OSC frequency is the first operating frequency. For example, after one adjustment process is finished, the second frequency offset of the OSC frequency of the product is 0.55%, that is, the frequency offset standard range of the OSC frequency is reached, and the adjustment process is finished, so in this example, the first operating frequency is 90.25M (1-0.55%) -89.75M. If the communication frequency range of the cellular communication module includes at least one of 89.75M frequency division and/or frequency multiplication, for example, the communication frequency of the cellular communication module is 1974.6M and 22 integer multiples of 89.75M, the OSC may generate severe interference to the cellular communication module, and report a first frequency hopping command generated by a wireless Access Point (AP) to trigger frequency hopping, so as to avoid the interference.

To assist understanding, please refer to fig. 8, where fig. 8 is a schematic frequency hopping diagram provided in the embodiment of the present application, and as shown in fig. 8, an electronic device first detects whether interference exists in a current cellular communication module, if so, reports to an AP to generate a frequency hopping instruction to trigger frequency hopping, and if not, maintains a detection state, and repeatedly detects whether interference exists in the current cellular communication module.

In one possible example, the generating, when it is detected that at least one frequency in the first frequency set corresponding to the current first operating frequency of the crystal oscillator is within the current communication frequency range of the cellular communication module, a first frequency hopping instruction includes: when detecting that at least one frequency in the first frequency set is in a communication frequency range corresponding to a traffic channel absolute wireless frequency channel number, generating the first frequency hopping instruction; when detecting that the intersection of the first frequency set and the communication frequency range corresponding to the service channel absolute wireless channel number is an empty set and at least one frequency in the first frequency set is in the communication frequency range corresponding to the broadcast channel absolute wireless channel number, generating the first frequency hopping instruction; and when detecting that the intersection of the first frequency set and the communication frequency range corresponding to the service channel absolute wireless channel number is an empty set, and the intersection of the first frequency set and the communication frequency range corresponding to the broadcast channel absolute wireless channel number is an empty set, and at least one frequency in the first frequency set is in the communication frequency range corresponding to the neighbor absolute wireless channel number, generating the first frequency hopping instruction.

Here, since the importance level of the traffic channel is greater than that of the broadcast channel in the cellular communication module of the electronic device than that of the other communication channels, when avoiding interference of the OSC with the cellular communication module using frequency hopping, the traffic channel absolute radio channel number (TCH ARFCN) has a higher priority than the broadcast channel absolute radio channel number (BCH ARFCN) than the Neighbor absolute radio channel number (Neighbor ARFCN). Exemplarily, if the interference channel corresponding to the current operating frequency 89.75M is a target interference channel, detecting whether the TCH ARFCN is in the target interference channel, and if the TCH ARFCN is in the target interference channel, requiring frequency hopping to generate a first frequency hopping instruction; if the TCH ARFCN is not in the target interference channel, detecting whether the BCH ARFCN is in the target interference channel, if the BCH ARFCN is in the target interference channel, needing frequency hopping, and generating a first frequency hopping instruction; if the BCH ARFCN is not in the target interference channel, detecting whether the Neighbor ARFCN is in the target interference channel, if the Neighbor ARFCN is in the target interference channel, needing frequency hopping, and generating a first frequency hopping instruction.

As can be seen, in this example, the electronic device performs priority ranking on each channel type in the communication module, so as to implement a priority interference prevention policy for an important channel, and can effectively stabilize the communication quality of the user equipment.

Step 403, in response to the first frequency hopping instruction, switching the first operating frequency to the second frequency according to the screen status of the electronic device.

In one possible example, the screen status of the electronic device includes the screen lightening status, the screen lightening status is a dynamic screen lightening status, and the switching the first operating frequency to the second frequency according to the screen status of the electronic device in response to the first frequency hopping instruction includes: and when the screen state of the electronic equipment is the dynamic bright screen state, responding to the first frequency hopping instruction, and switching the first working frequency to the second frequency.

When the screen state of the electronic equipment is a dynamic bright screen state, the switching of the working frequency can be directly realized by responding to the frequency hopping instruction, so that in the state, when the electronic equipment obtains a message and needs to perform frequency hopping, the first working frequency is directly switched to the second frequency by responding to the first frequency hopping instruction, other redundant steps are not performed, and the frequency hopping efficiency is improved.

Therefore, in this example, when the screen state of the electronic device is the dynamic bright screen state, the frequency switching is performed by directly responding to the first frequency hopping instruction, so that the frequency hopping efficiency can be effectively improved.

In one possible example, the screen state of the electronic device includes the bright screen state, where the bright screen state is a static bright screen state, and the switching the first operating frequency to the second frequency according to the screen state of the electronic device in response to the first frequency hopping instruction includes: when the screen state of the electronic equipment is the static bright screen state, generating a screen frame refreshing instruction according to the first frequency hopping instruction; responding to the screen frame brushing instruction to obtain a frame brushing result; and switching the first working frequency to the second frequency according to the first frequency hopping instruction and the frame refreshing result.

When the screen state of the electronic device is a static bright screen state, the refreshing of the picture frame is not performed because the screen state is static, and at this time, the frequency hopping cannot be realized even if the first operating frequency is switched to the second frequency. Therefore, in the application scene, when the frequency hopping is required, a screen frame refreshing instruction is generated according to the generated first frequency hopping instruction, and the frame is forcibly refreshed once according to the screen frame refreshing instruction, so that the frequency hopping is triggered.

To assist understanding, please refer to fig. 9, where fig. 9 is a schematic frequency hopping diagram in a static bright screen state according to an embodiment of the present application, and as shown in fig. 9, an electronic device first detects whether a current screen state is the static bright screen state, if not, maintains the detection state, repeatedly detects the current screen state, if yes, detects whether a frequency hopping instruction exists, if so, forcibly refreshes a frame, and if not, returns to the step of detecting the current screen state.

It can be seen that, in this example, when the screen state of the electronic device is the static bright screen state, the frequency is directly switched to disable frequency hopping, and a step of forcibly swiping a frame is added to ensure that a frame swiping action is performed in the static bright screen state, so as to ensure that frequency hopping is triggered, and the problem that frequency hopping in the static bright screen state cannot be implemented in the existing frequency hopping scheme is solved.

In one possible example, the screen state of the electronic device includes the screen-off state, and the switching the first operating frequency to the second frequency according to the screen state of the electronic device in response to the first frequency hopping instruction includes: when the screen state of the electronic equipment is the screen-off state, generating a data uploading instruction according to the first frequency hopping instruction; responding to the data uploading instruction, uploading the second frequency to a target storage node, wherein the target storage node is used for indicating data corresponding to the data uploading instruction; and if the screen state of the electronic equipment is detected to be changed from the screen-off state to the screen-on state, calling the target storage node, and switching the first working frequency to the second frequency.

In the prior art, when the screen status of the electronic device is the off-screen status, the cellular communication module is interfered, and then the screen is turned on after the off-screen status, the OSC frequency returns to the OSC frequency of the initial configuration, for example, 90.25M, and in the off-screen status, the OSC frequency is always 90.25M when the screen is turned on again no matter how the frequency is switched. In the application, when the screen state of the electronic device is a screen-off state, it is detected that the OSC needs frequency hopping, a first frequency hopping instruction is generated, a data uploading instruction is generated, a target frequency point, that is, a second frequency, is uploaded to a target storage node by responding to the data uploading instruction, and when it is detected that the screen is changed from the screen-off state to a screen-on state, the target storage node is called, and the first operating frequency is switched to the second frequency, so that frequency hopping is realized.

For assisting understanding, please refer to fig. 10, where fig. 10 is a schematic frequency hopping diagram in a screen-off state according to an embodiment of the present disclosure, and as shown in fig. 10, an electronic device first detects whether a current screen state is the screen-off state, if not, keeps the detection state, repeatedly detects the current screen state, and if so, detects whether a frequency hopping instruction exists; if the frequency hopping instruction is detected to be absent, returning to the step of detecting the current screen state, if the frequency hopping instruction is detected to be present, uploading the frequency of the target frequency point to a target storage node, detecting whether the screen is bright, if the screen is bright, calling the target storage node to complete frequency hopping, and if the screen is not bright, returning to the step of detecting whether the screen is bright.

It can be seen that, in this example, when the screen state of the electronic device is the screen-off state, the target frequency point is uploaded to the target storage node, and the target storage node is called to implement frequency switching after the screen is turned from the screen-off state to the screen-on state, so that frequency hopping of the electronic device from the screen-off state to the screen-on state is implemented, and the problem that frequency hopping in the screen-off state cannot be implemented in the existing frequency hopping scheme is solved.

In one possible example, after the switching the first operating frequency to the second frequency according to a screen status of the electronic device in response to the first frequency hopping instruction, the method further includes: when detecting that the communication frequency range of the cellular communication module changes, acquiring the changed communication frequency range; generating a second frequency hopping instruction according to a second frequency set corresponding to the second frequency and the changed communication frequency range, wherein the second frequency set is used for representing frequency division and/or frequency multiplication of the second frequency; and responding to the second frequency hopping instruction, and switching the second frequency to the first frequency according to the screen state of the electronic equipment.

By way of example and not limitation, when the electronic device finishes hopping from the first operating frequency 89.75M to the second frequency 88.9M, the OSC frequency of the electronic device changes to the second frequency 88.9M, thereby avoiding the communication frequency range of the cellular communication module. At this time, if the communication frequency range of the cellular communication module is changed, the changed communication frequency range includes at least one frequency point in the second frequency set corresponding to the second frequency 88.9M, and the OSC interferes with the cellular communication module, a second frequency hopping instruction is generated, and the OSC frequency is hopped from the second frequency 88.9M to the first frequency 90.25M.

As can be seen, in this example, after the electronic device hops to the second frequency, it is detected that the frequency range of the cellular communication module changes to the frequency range in which the second frequency causes interference, and then hops to the first frequency, so as to avoid interference to the cellular communication module in time.

In one possible example, the generating a second frequency hopping instruction according to the second frequency set corresponding to the second frequency and the changed communication frequency range includes: when detecting that at least one frequency in the second frequency set is in the updated communication frequency range corresponding to the absolute wireless channel number of the service channel, generating the second frequency hopping instruction; when it is detected that an intersection of the second frequency set and the updated communication frequency range corresponding to the service channel absolute wireless channel number is an empty set and at least one frequency in the second frequency set is in the updated communication frequency range corresponding to the broadcast channel absolute wireless channel number, generating the second frequency hopping instruction; when detecting that an intersection of the second frequency set and an updated communication frequency range corresponding to the service channel absolute wireless channel number is an empty set, and an intersection of the second frequency set and an updated communication frequency range corresponding to the broadcast channel absolute wireless channel number is an empty set, and at least one frequency in the second frequency set is in an updated communication frequency range corresponding to a neighbor absolute wireless channel number, generating the second frequency hopping instruction; and generating the second frequency hopping instruction when detecting that the intersection of the second frequency set and the updated communication frequency range corresponding to the service channel absolute wireless channel number, the intersection of the updated communication frequency range corresponding to the broadcast channel absolute wireless channel number, and the intersection of the updated communication frequency range corresponding to the neighbor absolute wireless channel number are all empty sets.

Even if the communication frequency range of the cellular communication module changes, the communication channel types still have priority orders of importance, so that when the cellular communication module is avoided from the interference of the OSC by frequency hopping, the TCH ARFCN has higher priority than the BCH ARFCN than the Neighbor ARFCN. Exemplarily, if the working frequency of the current OSC, that is, the interference channel corresponding to the second frequency 88.9M, is regarded as a target interference channel, it is first detected whether the TCH ARFCN is in the target interference channel, and if the TCH ARFCN is in the target interference channel, frequency hopping is required to generate a second frequency hopping instruction; if the TCH ARFCN is not in the target interference channel, detecting whether the BCH ARFCN is in the target interference channel, if the BCH ARFCN is in the target interference channel, needing frequency hopping, and generating a second frequency hopping instruction; if the BCH ARFCN is not in the target interference channel, detecting whether the Neighbor ARFCN is in the target interference channel, if the Neighbor ARFCN is in the target interference channel, needing frequency hopping, and generating a second frequency hopping instruction; if the Neighbor ARFCN is not in the target interference channel, that is, neither the TCH ARFCN, the BCH ARFCN nor the Neighbor ARFCN is in the target interference channel, that is, there is no interference to the cellular communication module, the second frequency hopping command is still generated, and the frequency is hopped to the first frequency of 90.25M, because the first frequency of 90.25M is the OSC theoretical value/standard value initially configured when the product leaves the factory, the operating yield of the product under the OSC operating frequency is the maximum, and therefore, if there is no interference at this time, the first frequency is hopped back, which is beneficial to improving the operating efficiency of the product and improving the user experience.

As can be seen, in this example, the electronic device performs priority ranking on each channel type in the communication module, so as to implement a priority interference prevention policy for important channels, and can effectively stabilize the communication quality of the user equipment, and when there is no interference, the OSC frequency is restored to the OSC theoretical value initially configured, so that the working efficiency of the user equipment can be improved, the operating smoothness is increased, and the user experience is improved.

It can be seen that, in the prior art, since a frequency of actual operation of the OSC after the electronic device leaves the factory has a large error from a calibrated standard frequency, and a frequency offset exceeds a standard range, when the electronic device hops to a target frequency point, the electronic device may fall back to an original interference frequency point, which may cause invalid frequency hopping. The frequency offset of the OSC operating frequency is adjusted from a first frequency offset to a second frequency offset, so that the OSC frequency returns to a standard error range, where frequency ranges of two preset reference frequency points (a first frequency and a second frequency) under the constraint of the second frequency offset are a first reference frequency subset and a second reference frequency subset, frequency ranges of the two reference frequency subsets after frequency division and/or frequency multiplication are a first reference frequency set and a second reference frequency set, respectively, and an intersection of the first reference frequency set and the second reference frequency set is an empty set, so that when the OSC frequency is the first frequency and interferes with the cellular communication module, the frequency hops to the second frequency, and at this time, since the frequency interfering with the cellular communication module is one of the first reference frequency set and the intersection of the first reference frequency set and the second reference frequency set is an empty set, it indicates that there is no frequency that can interfere with the cellular communication module in the second reference frequency set, that is, after frequency hopping to the second frequency is guaranteed, the situation that the frequency hopping falls back to the original interference frequency point does not occur, and then invalid frequency hopping is caused, so that the effectiveness of frequency hopping can be guaranteed, and moreover, the adaptive frequency hopping strategy can be automatically selected based on the difference of the screen states of the electronic equipment, so that the effective frequency hopping in the full scene state is realized, and thus, the use experience of the user can be greatly improved.

The embodiment of the application provides a navigation information processing device which can be a first user equipment. Specifically, the navigation information processing apparatus is configured to perform the steps performed by the first user equipment in the above navigation information processing method.
