Description

Control method and device for positioning confidence

Technical Field

The present application relates to the field of communications technologies, and in particular, to a method and an apparatus for controlling a positioning confidence.

Background

Currently, the third Generation Partnership project (3 GPP) Technical Report (TR) 22.872 defines a preliminary concept for location reliability. Confidence is a measure of confidence, where confidence refers to the degree of confidence in the correctness of the information provided by the navigation system; the confidence level also includes the capability of providing timely and effective alarm to the positioning request initiated by the terminal device, the functional entity in the 5G Core Network (5G Core Network,5 gc), or other application functions inside/outside the serving Public Land Mobile Network (PLMN) when the positioning system does not satisfy the predetermined operating condition (for example, when the positioning error is large).

In the prior art, only the preliminary study on the reporting of the positioning measurement error exists, and no specific implementable scheme exists for the positioning confidence alarm method, so that the positioning confidence in the positioning system cannot be effectively controlled, and the accuracy and the reliability of the positioning system are poor.

Disclosure of Invention

The embodiment of the application provides a control method and device for positioning confidence, which are used for timely and accurately controlling equipment in a positioning system to perform alarm on the positioning confidence, so that the accuracy and reliability of the positioning system are improved.

In a first aspect, a control method for positioning confidence is provided, including: receiving a first notification; wherein the first notification comprises information related to location confidence; starting a first counter according to the first notification, and after the first counter starts counting and within the preset duration of the first timer, receiving the first notification again or for multiple times, adding 1 to the count value of the first counter, and restarting the first timer; and executing the alarm about the position reliability after determining that the count value of the first counter reaches the upper counting limit or after determining that the count value of the first counter reaches the upper counting limit.

In the above scheme, by nesting the first timer in the first counter, the alarm is executed only after the first notification including the relevant information of the position reliability is received for the first time and then the first notification triggering the alarm is received continuously for multiple times, that is, the position reliability is poor in stability in a long time period. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the positioning confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved.

In a possible implementation manner, after the first counter starts counting and within a preset time duration of the first timer, if the first notification is not received again, the first counter may be reset.

In this implementation, after the first counter starts counting and within the preset duration of the first timer, if the first notification is not received again, it is indicated that the fixed-position reliability is not stably maintained in a poor state for a long time, and the resetting of the counter can control the non-execution of the alarm, thereby avoiding the occurrence of false alarm and false alarm caused by the ping-pong effect.

In a possible implementation manner, the first counter is reset and the first timer is stopped when or after the count value of the first counter reaches the upper count limit.

In this implementation manner, when or after the count value of the first counter reaches the upper limit of the count, the first counter is reset, and the function of the first timer is completed, so that the first timer is stopped, the positioning system can be ensured to reliably operate, and the reliability of the scheme is improved.

In a possible implementation manner, the duration of the first timer is greater than or equal to the first detection period related to the positioning confidence.

In this implementation manner, the duration of the first timer is greater than or equal to the first detection period related to the positioning confidence, so that it can be ensured that a new first notification can be received at least once within the duration of the first timer, and the reliability of the scheme is improved.

In a possible implementation manner, the starting time of the first timer is the time of receiving the first notification; or the starting time of the first timer is not later than the time of receiving the first notice; or the starting time of the first timer is the starting time of a first detection period about the positioning confidence coefficient after the time of receiving the first notification; or the starting time of the first timer is any time between the time of receiving the first notification and the starting time of the first detection period of the first positioning confidence coefficient after the first notification is received.

In the implementation mode, various implementation modes are provided aiming at the starting time of the first timer, and the flexibility of the scheme can be improved while the reliability of the scheme is ensured.

In one possible implementation, the alert regarding location confidence includes one or more alert levels; different alarm levels in the plurality of alarm levels correspond to different groups of first timers and first counters, wherein the duration of the first timer is positively or negatively correlated with the alarm level, the upper limit of the count of the first counter is positively or negatively correlated with the alarm level, or different alarm levels in the plurality of alarm levels correspond to the same group of first timers and first counters.

In the implementation mode, different first timers and first counters are configured according to different alarm levels, so that alarms with different confidence coefficient risks can have different response speeds, the control accuracy of the positioning confidence coefficient can be improved, and the position confidence coefficient of the positioning system can be better ensured. And the same group of first timer and first counter are configured aiming at different alarm levels, so that the system complexity can be reduced, and the design cost can be reduced.

In a possible implementation manner, the first notification may further include first information, and the first information may be used to indicate one of the one or more alert levels. Correspondingly, the method may further comprise: and determining the alarm level according to the first information, and starting a group of first timers and first counters corresponding to the alarm level.

In the implementation mode, the first information is carried in the first notification to indicate the current alarm level, so that a group of first timer and first counter corresponding to the current alarm level can be quickly determined through the first information, and the starting efficiency of the first timer and the first counter can be improved.

In one possible implementation, the relevant information is used to trigger an alarm about the position confidence.

In the implementation mode, the first notice carries the relevant information for triggering the alarm about the position reliability, so that the alarm efficiency about the position reliability can be improved, and the user experience is improved.

In a second aspect, a control method for positioning confidence is provided, which includes: receiving a first notification; wherein the first notification comprises information related to location confidence; starting a second timer according to the first notification, and after the second timer is started, adding 1 to the count value of a second counter in each of one or more continuous second detection periods related to the positioning confidence coefficient when the first notification is received again or for multiple times, otherwise resetting the second counter; performing an alert regarding location confidence upon determining that the second timer has expired and that the count value of the second counter is not a reset value.

In the above scheme, by nesting the second counter in the second timer, the device can execute the alarm only after the first notification triggering the alarm is received for a certain time duration subsequently and the first notification is received within the time duration for a preset number of times after the first notification triggering the alarm is received for the first time, that is, the positioning confidence is relatively poor in stability within the time duration. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved.

In a possible implementation, the method further includes: and when the second timer is determined to be expired or later and the count value of the second counter is not a reset value, resetting the second counter and stopping the second timer.

In this implementation manner, when or after the second timer expires and the count value of the second counter is not the reset value, the second counter is reset, and the function of the second timer is performed completely, so that the second timer is stopped, the positioning system can be ensured to run reliably, and the reliability of the scheme is improved.

In a possible implementation, the method further includes: and stopping the second timer if the first notice is not received again in at least one second detection period in one or more continuous second detection periods related to the positioning confidence coefficient.

In this implementation, if the timer is started, as long as a second detection period does not receive the first notification, the count value of the second counter is cleared and the timer is stopped. Therefore, the alarm can be initiated after the first notice is received in a plurality of continuous second detection periods, and the situations of false alarm and false alarm caused by the ping-pong effect are avoided.

In a possible implementation manner, the duration of the second timer is greater than or equal to the product of the upper count limit of the second counter and the second detection period.

In this implementation manner, setting the duration of the second timer to be greater than or equal to the product of the upper counting limit of the second counter and the second detection period may ensure that the first notification can be received again (or multiple times) within the duration of the second timer, so that the second counter can function.

In one possible implementation, the alert regarding location confidence includes one or more alert levels; different alarm levels in the plurality of alarm levels correspond to different groups of second counters and second timers, wherein the duration of the second timer is positively or negatively correlated with the alarm level, the upper count limit of the second counter is positively or negatively correlated with the alarm level, or different alarm levels in the plurality of alarm levels correspond to the same group of second counters and second timers.

In the implementation mode, different second timers and second counters are configured according to different alarm levels, so that alarms with different confidence level risks can have different response speeds, the control accuracy of the positioning confidence level can be improved, and the positioning confidence level of the positioning system can be better ensured. And the same group of second timer and second counter are configured aiming at different alarm levels, so that the system complexity can be reduced, and the design cost can be reduced.

In a possible implementation, the method further includes: the first notification comprises second information, and the second information is used for indicating one of the one or more alarm levels; and determining the alarm level according to the second information, and starting a group of second counters and second timers corresponding to the alarm level.

In this implementation manner, the second information carried in the first notification indicates the current alert level, so that a group of the second timer and the second counter corresponding to the current alert level is quickly determined through the second information, and the starting efficiency of the second timer and the second counter can be improved.

In the implementation mode, the first notification carries the relevant information for triggering the alarm about the position reliability, so that the alarm efficiency about the position reliability can be improved, and the user experience is improved.

In a third aspect, a method for controlling a positioning confidence is provided, including: receiving a first notification; wherein the first notification comprises information related to location confidence; starting a third timer according to the first notice, and executing an alarm about the position reliability within the duration of the third timer or when the third timer expires; or starting a third counter according to the first notice, and executing the alarm about the position reliability when the count value of the third counter reaches the upper counting limit or after the count value reaches the upper counting limit.

In the above scheme, the alarm about the location reliability is controlled by setting an independent timer or counter, so that on one hand, the equipment can perform the alarm when the location reliability is relatively poor in stability within the duration, thereby effectively avoiding the situation of 'false alarm', and on the other hand, the system complexity can be reduced, and the design cost can be reduced.

In a possible implementation, the method further includes: stopping the third timer if the alert is performed for the duration of the third timer; alternatively, the third timer is stopped at or after expiration of the third timer.

In this embodiment, when the alarm is executed during the duration of the third timer, or when or after the third timer expires, the third timer is completely used, and therefore the first timer is stopped, the positioning system can be ensured to reliably operate, and the reliability of the scheme can be improved.

In one possible implementation, the alert regarding location confidence includes one or more alert levels; different alarm levels in the plurality of alarm levels correspond to different third timers, wherein the duration of the third timer is positively or negatively correlated with the alarm level, or different alarm levels in the plurality of alarm levels correspond to the same third timer.

In this implementation, if different third timers are configured for different alarm levels, alarms with different confidence risks may have different response speeds, so that the control accuracy of the positioning confidence can be improved, and the position confidence of the positioning system can be better ensured. If the same third timer is configured for different alarm levels, the system complexity can be reduced, and the design cost can be reduced.

In a possible implementation, the method further includes: the first notification comprises third information, and the third information is used for indicating one of the one or more alarm levels; and determining the alarm grade according to the third information, and starting a third timer corresponding to the alarm grade.

In this implementation manner, the third information is carried in the first notification to indicate the current alarm level, so that a third timer corresponding to the current alarm level is quickly determined by the third information, and the starting efficiency of the third timer can be improved.

In a possible implementation, the method further includes: after the third counter is started, receiving the first notification again or more times in each of one or more continuous third detection periods related to the positioning confidence, and adding 1 to the count value of the third counter, otherwise resetting the third counter; performing an alert regarding location confidence upon or after determining that the count value of the third counter has reached an upper count limit.

In this implementation, the first device will only perform an alarm after receiving the first notification (reaching the upper limit of the count) for a plurality of times, which can effectively avoid the situation of "false alarm" and further ensure the confidence of the positioning system.

In a possible implementation, the method further includes: resetting the third counter upon or after determining that the count value of the third counter reaches an upper count limit.

In this implementation manner, when or after the count value of the first counter reaches the upper limit of the count, an alarm is executed, and the function of the third counter is performed, so that the third counter is reset, the positioning system is ensured to operate reliably, and the reliability of the scheme is improved.

In one possible implementation, the alert regarding location confidence includes one or more alert levels; different alarm levels in the alarm levels correspond to different third counters, wherein the upper counting limit of the third counter is positively or negatively correlated with the alarm levels, or different alarm levels in the alarm levels correspond to the same third counter.

In this implementation, if different third counters are configured for different alarm levels, alarms with different confidence risks may have different response speeds, so that the control accuracy of the positioning confidence may be improved, and the position confidence of the positioning system may be better ensured. If the same third counter is configured for different alarm levels, the complexity of the system can be reduced, and the design cost can be reduced.

Specifically, the embodiment of the application relates to a control method and device for positioning confidence, which can ensure the confidence of a positioning system and improve the reliability of the positioning system.

In the following, some technical terms related to the embodiments of the present application will be explained.

1) Timer (Timer): the timer is mainly used for timing in a digital system, and can realize the functions of timing, controlling and the like, and the timer mainly comprises the following attributes:

start (Start): the timer is started to meet certain conditions. For example, in the following, the condition for starting the timer may be that the first notification is received.

Stop (Stop): the early expiration of the timer during run-time requires certain operations to be performed. For example, in the following, the condition that the timer ends early during the run may be that an alarm is performed.

Duration (Duration): the time interval between the start of the timer and the first expiration must be greater than 0. For example the duration of one or more time slots.

Expiration (At expiration): i.e., the expiration of the timer, typically triggers the execution of some predetermined operation. For example, in the following, the expiration of a timer may trigger an alarm or a counter incremented by 1, etc.

2) Counter (Counter): the counter mainly counts the number of pulses in a digital system to realize the functions of measurement, counting and control, and has a frequency division function. The counter mainly includes the following attributes:

reset (Reset): that is, the count value of the counter is reset when a certain condition is satisfied, and the reset count value (i.e., reset value) may be any value, for example, 0, 1, 2, 3, or the like.

Increment (Increment): which identifies the range to which the counter is actually associated, the count value of the counter may be incremented when a certain condition is met.

Counter upper limit (Max value): that is, the maximum value of the count value of the counter, and the count value of the counter reaches the upper limit, the execution of some preset operations is generally triggered. For example, hereinafter, an alarm or resetting of the counter may be performed after the count value of the counter reaches the upper limit.

3) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone, wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions, refer to any combination of these items, including single item(s) or multiple items(s), such as at least one of a, b, or c, which may represent: a, or b, or c, or a and b, or b and c, or a and b and c.

And, unless stated to the contrary, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing a plurality of objects, and do not limit the sequence, timing, priority, or importance of the plurality of objects. For example, the first priority criterion and the second priority criterion are only used for distinguishing different criteria, and do not represent the difference of the content, priority, importance, and the like of the two criteria.

A method for controlling the positioning confidence according to an embodiment of the present application will be described below with reference to the flowchart of fig. 2 as an example.

The method shown in fig. 2 may be applied to the communication system shown in fig. 1, and an execution subject of the method may be executed by any network element or entity or device in the communication system shown in fig. 1, such as an LMF or a terminal, as long as the network element or entity or device has a positioning calculation capability, which is not limited in the embodiment of the present application. For convenience of description, a network element or entity or device that will perform the method is exemplified below as the first device.

As shown in fig. 2, a control method for localization confidence includes:

s201, the first device receives a first notification.

The first device may be an LMF or a terminal, which is not limited herein. The first notification may be generated by the first device itself, or the first notification may be sent by the second device to the first device, which is not limited herein. For example, taking the second device sending the first notification to the first device as an example, when the first device is an LMF, the second device may be a terminal, a base station, or the like; when the first device is a terminal, the second device may be an LMF, a base station, etc.

Wherein the first notification includes location confidence related information that may be used to trigger an alert regarding the location confidence. For example, the first notification may be a notification message generated by the first device when the positioning confidence does not satisfy a preset condition, or a notification message generated by the second device and sent to the first device, where the preset condition may be a determination condition for determining whether an alarm about the location confidence needs to be performed. For example, the preset condition may be that a confidence crisis is about to occur in the positioning system, that is, it is determined that the positioning system needs to alarm when the confidence crisis is about to occur in the positioning system, and a first notification is triggered and reported, and a first device is triggered to alarm in time when the confidence crisis about to occur in the positioning system through the first notification, so that the relevant devices in the positioning system can take effective measures in advance to adjust, instead of waiting for the system to be completely unavailable, and thus, the requirement of the system on the position confidence can be met.

When the first notification is a notification message generated when the position reliability does not meet the preset condition, the first notification may be all notification messages in the positioning system or only part of notification messages in the positioning system. These two cases are described separately below:

in the first detection period of each positioning confidence coefficient, the positioning system only has a notification message when the detection result represents that the position confidence coefficient does not meet the preset condition, and the notification message only has one type of notification message for triggering an alarm. In this case, the first notification is all notification messages received by the first device. Optionally, all notification messages may include a determination result that an alarm about the location reliability needs to be performed.

In category 2, in each first detection period related to the confidence level of the location, no matter whether the detection result indicates that the confidence level does not satisfy the preset condition, there are notification messages, and at this time, the notification messages include two types, namely, a notification message (first notification) that triggers an alarm and a notification message (second notification) that does not trigger an alarm. In this case, both the first notification and the second notification may occur, so the first notification may be only the portion of the notification message received by the first device to trigger the alert. Alternatively, the first notification may include a determination result that an alarm about the position reliability needs to be performed, the second notification may not include a determination result that an alarm about the position reliability needs to be performed, or the second notification may include a determination result that an alarm about the position reliability does not need to be performed.

It should be understood that the first detection period may be a period for the second device to detect whether the positioning confidence satisfies a preset condition, for example, if the second device detects that the positioning confidence once every 10 slots (slots) satisfies the preset condition, the period duration is 10 slots. The duration of the detection operation executed by the second device in each period is less than or equal to the period duration, for example, when the period duration is 10 slots, the detection operation may be executed in the first 5 slots of each period, and the last 5 slots are used to report the first notification to the first device, or the detection operation is executed in all 10 slots, and the first notification is reported immediately once it is detected that the positioning confidence does not satisfy the preset condition. In addition, the first detection period may be a self-set period, for example, the set period may be equal to M periods for detecting whether the positioning confidence level satisfies the preset condition, where M is a positive number. For convenience of description, the first detection period in the following text takes a period for detecting whether the localization confidence satisfies a preset condition as an example.

Optionally, in this embodiment, the positioning confidence may be related to error information of the positioning system. The relevant indicators for evaluating the localization confidence may include:

1) Alarm Limit (AL): including horizontal and/or vertical alarm limits. Wherein the horizontal alarm limit is a maximum allowable horizontal position error and the vertical alarm limit is a maximum allowable vertical position error, and if the horizontal position error of the positioning system exceeds the horizontal alarm limit and/or the vertical position error of the positioning system exceeds the vertical alarm limit, it indicates that the positioning system is not suitable for the intended application. The value of the index is usually preset and can be related to a specific positioning service.

2) Time To Alert (TTA): the maximum allowable time that passes from when the actual error of the positioning system exceeds the error tolerance to before the device issues an alarm. The value of the index is usually preset and can be related to a specific positioning service.

3) Confidence risk (IR): confidence risk refers to the probability that a positioning error exceeds an alarm limit, i.e., the probability that the confidence of the system is at risk. The value of the index is also generally preset and can be related to a specific positioning service.

4) Positioning Error (PE): i.e. positioning errors of the terminal device.

5) Protection Level (PL): including horizontal/vertical protected horizontal. Horizontal/vertical protection horizontal refers to the upper statistical bound of positioning errors in the horizontal/vertical direction. The background of the index is as follows: in actual operation, for a terminal with high mobility, such as an airplane, since the real position of the airplane cannot be known, and therefore the real positioning error cannot be known, new parameters need to be proposed to measure the possibility that the positioning error exceeds the alarm limit. Illustratively, the indicator can pass Prob (PE) if the distribution of the positioning error can be obtained by measurement<PL)＝ε _PL Is calculated to obtain wherein ∈ _PL Is a preset threshold value, which may be related to a specific positioning service.

6) Error Bounding (EB): and is also an upper bound of positioning error, which is used to ensure the accuracy of positioning.

The system may set the preset condition according to any one or more of the above-mentioned indicators, that is, determine whether an alarm is required according to any one or more of the above-mentioned indicators. For example, whether or not an alarm is required is determined from PL and AL, or whether or not an alarm is required is determined from PE and AL, and the like.

It should be noted that the above-mentioned index for determining whether an alarm is needed is only an example and is not limited, and whether a system alarms or an alarm level may also be determined according to other indexes in specific implementation.

Further optionally, in the embodiment of the present application, the alarm may have a plurality of alarm levels. The value of the alarm level may be positively correlated with the risk degree, and the value of the alarm level may also be negatively correlated with the risk degree, which is not limited in the embodiment of the present application. For convenience of description, the following description will take the case where the numerical value of the alarm level is positively correlated with the risk level, for example, assuming that there are three alarm levels in total, the first alarm level has the lowest risk level and the third alarm level has the highest risk level.

S202, the first equipment starts a first counter according to a first notice, receives the first notice again or repeatedly after the first counter starts counting and within the preset duration of the first timer, adds 1 to the count value of the first counter, and restarts the first timer; and executing the alarm about the position reliability after determining that the count value of the first counter reaches the upper limit of the count value.

The preset duration of the first timer may be equal to or less than the duration of the first timer, and this embodiment of the present application is not limited. For convenience of description, the preset duration of the first timer is mainly taken as an example to be equal to the duration of the first timer hereinafter. The duration of the first timer may be greater than or equal to the first detection period with respect to the localization confidence. For example, the first detection period < duration of the first timer <2 x the first detection period. In this way, it can be ensured that a new first notification can be received at least once within the first timer duration.

The first counter may start counting from any number, such as 0, 1, 2, or 3, and the embodiments of the present application are not limited. For convenience of description, the first counter is exemplified by counting from 0 in the following text. Similarly, the first counter may be reset to zero, i.e. the reset value is 0, or may be reset to 1, 2 or 3. For convenience of description, the following resetting of the first counter is taken as an example of zero clearing.

Optionally, if the first device does not receive the first notification again after the first counter starts counting and within the preset time length of the first timer, the first counter is reset. After the first counter is reset, if the first notification is received again, S202 may be performed again.

Optionally, the first device resets the first counter when the count value of the first counter reaches the upper limit of the count, and stops the first timer; or the first equipment resets the first counter and stops the first timer after the count value of the first counter reaches the upper limit of the count and before the alarm is executed; or after the first device executes the alarm, resetting the first counter and stopping the first timer; or after the first device executes the alarm and before the first notification is received next time, the first device resets the first counter and stops the first timer. In this way, reliable operation of the positioning system can be ensured.

Optionally, the starting time of the first timer satisfies: the start time of the first timer is the time of receiving the first notification (specifically, the time of receiving the first notification in S201); or, the starting time of the first timer is not later than the time of receiving the first notification (specifically, the time of receiving the first notification in S201); or, the starting time of the first timer is the starting time of a first detection period after the time of receiving the first notification (specifically, the time of receiving the first notification in S201); alternatively, the start time of the first timer may be any time between the time when the first notification is received (specifically, the time when the first notification is received in S201) and the start time of the first detection period after the first notification is received.

In order to more clearly understand the technical solution of the embodiment of the present application, the following describes an exemplary setting of the first timer and the related attribute of the first counter.

The relevant properties of the first timer may be set as follows:

1) Start (Start): the first device receives the first notification.

2) Stop (Stop): when the first counter reaches the upper count limit.

3) Time expired (At expire): and if the first notice is received once or more times within the preset time length of the first timer, adding 1 to the count value of the first counter.

The relevant attributes of the first counter are set as follows:

1) Reset (Reset): and resetting the first counter after the first notice is received for the first time, or the count value of the first counter reaches the upper limit, or the first notice is not received again within the preset duration of the first timer. Illustratively, the count value may be reset to 0.

Wherein, the first receiving of the first notification may include the following: after a long time of idle (i.e. no first notification is received for a long time), a first notification corresponding to the first alarm level is received for the first time. For example, the first device receives the first notification at time t2, the time of receiving the first notification the last time before time t2 is time t1, and the time interval between time t1 and time t2 exceeds the preset value, then the first notification received at time t2 may be regarded as the first notification received for the first time. It should be understood that step S201 is the case where the first notification is received for the first time.

2) Count plus 1 (included): and if the first notice is received once or more times within the preset time length of the first timer, the count value of the first counter is increased by 1.

3) Upper count value (When stopping max value): and stopping the first timer and triggering an alarm.

The operation of the first timer and the first counter is described below with reference to a specific example.

Referring to fig. 3, the duration of the first timer is set to 1.5 slots, the preset duration of the first timer is set to 1.5 slots, the upper limit of the count of the first counter is set to 3, and the first detection period is the time length of 1 slot.

slot0, when the first device receives the first notice for the first time, starting a first counter N and starting a first timer (starting a first timing period T-1 of the first timer);

slot1, the first device receives the first notice again twice, but the first timing period T-1 of the first timer has not expired yet, so the count value of the first counter is unchanged temporarily;

slot2, T-1 expires at the starting time of slot2, at this time, since the first notification is received at least once (twice in fig. 3) in the first timing period (in slot 1), the count value of the first counter is +1, n =1, and the first timer is restarted (the second timing period T-2 of the first timer is started); after restarting the first timer, receiving the first notice in slot2 again, but the second timing period is not finished at the moment, so the count value of the first counter is unchanged temporarily;

slot3, the second timing period T-2 of the first timer ends, and at this time, since the first notification (in slot 2) is received once again in the second timing period T-2, the count value +1 of the first counter, that is, N =2, restarts the first timer (starts the third timing period T-3 of the first timer); after the first timer is restarted, the first notice is received in slot3, but the third timing period T-3 is not ended at the moment, so the count value of the first counter is unchanged temporarily;

slot4, in the third timing period T-3, the first device receives the first notification once again, and in the third timing period T3, the first notification is received twice in total, but T-3 is not expired, so the count value of the first counter is temporarily unchanged;

slot5, the third timing period T-3 expires, the counter +1, at this time N =3, the first counter reaches the upper limit of the count, the first device executes the alarm, resets the counter, and stops the first timer;

slot6, no first notification;

a Slot7, after a first device receives a first notification after a long time interval, if the first notification received in the Slot7 can be regarded as the first notification, a first counter is started, and a first timer is started (a first timing period T-1 of the first timer is started);

slot8, T1 expires, but the first notification is not received again before and at the expiration of T1, so the first counter is not incremented by 1 and the first notification received in Slot7 is considered a "false alarm".

Through the above process, by matching the first counter and the first timer, the first device may perform the alarm only after receiving the first notification for the first time and subsequently receiving the first notification for triggering the alarm for a plurality of times, that is, when the confidence of the positioning system does not satisfy the preset condition stably for a long time. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved.

Further, if the alarm related to the positioning confidence includes a plurality of alarm levels, different alarm levels may correspond to different sets of the first timer and the first counter (where a set of the first timer and the first counter includes one first timer and one first counter), or correspond to the same set of the first timer and the first counter, and the embodiment of the present application is not limited thereto. The specific implementation manner of the first timer and the first counter corresponding to the same group in multiple alarm levels may refer to the embodiment shown in fig. 3, which is not described here.

When different alarm levels correspond to different sets of the first timer and the first counter, the duration of the first timer and/or the upper limit of the count of the first counter may be positively or negatively correlated with the alarm level. For example, the higher the alert level, the shorter the expiration time of the first timer, and the smaller the upper count limit of the first counter.

The above three alarm levels are used for example: table 1 shows the relevant attribute settings of the first timer corresponding to each level, and table 2 shows the relevant attribute settings of the first counter corresponding to each level, where the alarm level 1 corresponds to the first timer T1 and the first counter N1, the alarm level 2 corresponds to the first timer T2 and the first counter N2, and the alarm level 3 corresponds to the first timer T3 and the first counter N3. The size relationship of the duration of the three first timers is as follows: t1> T2> T3. The magnitude relation of the upper limit of the count of the three first counters is as follows: n1> N2> N3.

TABLE 1

TABLE 2

In another possible implementation, in case of a first timer resource shortage, different alert levels may share one first timer (common first timer) and/or a first counter (common first counter). Taking the example of sharing one first timer (common first timer), the related attribute of the common first timer is set as follows:

TABLE 3

That is, the first timer and the first counter may be configured in conjunction with tables 2 and 3 to implement the alarm control.

In a possible implementation manner, the first notification may carry first information about an alarm level, which is used to indicate one of a plurality of alarm levels. Therefore, the first equipment can quickly determine one alarm level according to the first information, and start a group of first timer and first counter corresponding to the alarm level, so that the starting efficiency of the first timer and the first counter can be improved.

According to the scheme, the first timer is nested in the first counter, so that after the first notification about triggering the alarm is received for the first time, the first equipment can execute the alarm only after the first notification about triggering the alarm is subsequently received for a certain duration and reaches a certain number of times, namely the confidence of the positioning system does not meet the preset condition stably for a long time. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved. In addition, the scheme also configures different first timers and first counters aiming at different alarm levels, so that the alarm with higher confidence risk is executed more timely, the confidence of the positioning system can be further improved, and the user experience is improved.

Another control method for the positioning confidence according to the embodiment of the present application will be described below by taking the flowchart of fig. 4 as an example.

The method shown in fig. 4 may be applied to the communication system shown in fig. 1, and a main execution body of the method may be executed by any network element or entity or device in the communication system shown in fig. 1, for example, an LMF or a terminal, as long as the network element or entity or device has a location calculation capability, which is not limited in the embodiment of the present application. For convenience of description, a network element or entity or device that will perform the method is exemplified below as the first device.

As shown in fig. 4, a control method for localization confidence includes:

s401, the first device receives a first notification.

Wherein the first notification includes location confidence related information that may be used to trigger an alert regarding location confidence. The specific implementation manner of this step may refer to the specific implementation manner of step S201 above, and is not described here again.

S402, the first device starts a second timer according to a first notification, and after the second timer is started, in each of one or more continuous second detection periods related to the positioning confidence coefficient, the first notification is received again or for multiple times, the count value of the second counter is increased by 1, otherwise, the second counter is reset; upon determining that the second timer has expired and that the count value of the second counter is not a reset value (i.e., a value to which the second counter has been reset), an alert regarding position confidence is performed.

It should be understood that the second detection period may be a period for detecting whether the positioning confidence coefficient satisfies a preset condition, and may also be different from the period for detecting whether the positioning confidence coefficient satisfies the preset condition, and is not limited herein. The second detection period may be the same as the first detection period, or may be different from the first detection period, and is not limited herein. For convenience of description, the second detection period in the following text is taken as an example of a period for detecting whether the localization confidence satisfies the preset condition.

The second counter may start counting from any number, such as 0, 1, 2, or 3, and the like, and the embodiments of the present application are not limited. For convenience of description, the second counter following this document takes counting from 0 as an example. Similarly, the second counter may be reset to zero, i.e. the reset value is 0, or may be reset to 1, 2, or 3. For convenience of description, the resetting of the second counter is performed by zero.

Optionally, if the first device does not receive the first notification again in at least one second detection period within one or more consecutive second detection periods with respect to the positioning confidence, the second timer is stopped. That is, if the timer starts, as long as a second detection period does not receive the first notification, the count value of the second counter is cleared and the timer is stopped. Therefore, the alarm can be initiated after the first notice is received in a plurality of continuous second detection periods, and the situations of false alarm and false alarm caused by the ping-pong effect are avoided.

Optionally, when it is determined that the second timer expires and the count value of the second counter is not the reset value, the first device resets the second counter, and stops the second timer; or after determining that the second timer expires and the count value of the second counter is not the reset value, the first device resets the second counter and stops the second timer; or the first device resets the second counter and stops the second timer after determining that the second timer expires and the count value of the second counter is not the reset value and before executing the alarm; or after the first device executes the alarm and before the first notification is received next time, the first device resets the second counter and stops the second timer. In this way, reliable operation of the positioning system can be ensured.

Optionally, the duration of the second timer is greater than or equal to the product of the upper count limit of the second counter and the second detection period. In this way, it is guaranteed that the first notification can be received again (or several times) within the duration of the second timer, so that the second counter can function. It should be appreciated that the upper limit of the count of the second counter in such a design cannot be infinite.

In order to more clearly understand the technical solution of the embodiment of the present application, the following describes an exemplary setting of the relevant attributes of the second timer and the second counter.

The relevant properties of the second timer may be set as follows:

1) Start (Start): the first notification is received for the first time.

It should be appreciated that the first receipt of the first notification may include the following: after a long time of idle (i.e. no first notification is received for a long time), a first notification corresponding to the first alarm level is received for the first time. For example, the first device receives the first notification at time t2, the time of receiving the first notification the last time before time t2 is time t1, and the time interval between time t1 and time t2 exceeds the preset value, then the first notification received at time t2 may be regarded as the first notification received for the first time.

2) Stop (Stop): when the second timer expires and the first device executes the alarm, stopping the second timer; alternatively, the second timer is not expired but during which the first notification is not continuously received, the second counter is reset without issuing an alarm, so the second timer is stopped.

3) Time expired (At expiry): an alarm is executed.

The relevant properties of the second counter are set as follows:

reset (Reset): after the first notification is received last time, the first notification is not continuously received.

It should be understood that the discontinuous reception of the first notification here means that the first device does not receive the first notification in a first second detection period after the second detection period in which the first notification is received last time is over. Taking the second detection period equal to 1 slot as an example, the first device receives the first notification at slot0 for the first time, starts the second counter, and N =0; if the first notification is received again in slot1, that is, if the first notification is continuously received, the second counter is incremented by 1, that is, N =1; and if the first notification is not received again in slot2, it means that the first notification is not continuously received in slot2, and the counter is reset to 0.

2) Count plus 1 (included): and after the first notice is received last time, continuously receiving the first notice again. It should be appreciated that the first notification is received a plurality of times in succession during a second detection period, and the count is incremented by 1.

3) Upper count value (When stopping max value): the second counter is reset.

It should be understood that the upper limit of the count of the second counter should be reasonably set here, for example, the upper limit of the count is larger than the maximum number of times the first notification may be received within the duration of the second timer. In this way, it can be ensured that the second counter is not reset because the second counter reaches the upper counting limit within the duration of the second timer, and the first device is ensured to reset the second counter only when the first notification is not continuously received. In one possible implementation, the upper limit of the second counter may be set to infinity, or the second counter may not have an upper count limit.

The working method of the second timer and the second counter is described below with reference to two specific examples:

example 1: referring to fig. 5A, the duration of the second timer is set to 5 slots, the upper limit of the count of the second counter is + ∞, the second detection period of the confidence alarm of the positioning system is 1 slot (slot), that is, each slot of the second device detects whether the confidence of the positioning system meets the preset condition once, and if not, the first notification is sent to the first device.

slot0, when the first device receives the first notification for the first time, the first device starts a second counter N (for example, counting from 0, N = 0), and starts a second timer T;

slot1, the first device receives the first notification again, the second timer has not ended, and the count value of the second counter is +1 (N = 1);

slot2, the first device receives the first notification again, the second timer has not ended yet, and the count value of the second counter is +1 (N = 2);

slot3, the first device receives the first notification again, the second timer has not ended yet, and the count value of the second counter is +1 (N = 3);

slot4, the first device receives the first notification again, the second timer has not ended yet, and the count value of the second counter is +1 (N = 4);

slot5, the first device receives the first notification again, and the count value of the second counter is +1 (N = 5); at this point, the second timer expires and the first device performs an alarm.

Example 2: referring to fig. 5B, the duration of the second timer is set to 5 slots, the upper limit of the count of the second counter is + ∞, the second detection period of the confidence alarm of the positioning system is 1 slot (slot), that is, each slot of the second device detects whether the confidence of the positioning system meets the preset condition once, and if not, the first notification is sent to the first device.

slot3, the first device does not receive the first notification, although the second timer has not expired, stops the second timer and resets the second counter.

Through the above process, by matching the second counter and the second timer, after the first notification about triggering the alarm is received for the first time, the first device will perform the alarm only after the first notification about triggering the alarm is subsequently received for a certain duration and the first notification is received within the duration for the preset number of times, that is, the positioning confidence level stably does not meet the preset condition within the duration of the second timer. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved.

Optionally, if the alarm for the confidence level in the positioning system includes multiple alarm levels, different alarm levels in the multiple alarm levels may correspond to different sets of the second timer and the second counter, or correspond to the same set of the second timer and the second counter, which is not limited in the embodiment of the present application.

Further optionally, when different alarm levels correspond to different sets of the second timer and the second counter, the duration of the second timer and/or the upper limit of the count of the second counter may be positively or negatively correlated with the alarm level. For example, the higher the alert level, the shorter the expiration time of the second timer, and the smaller the upper count limit of the second counter.

The above three alert levels are followed for example: table 4 shows the relevant attribute settings of the second counters corresponding to the respective levels, and table 5 shows the relevant attribute settings of the second timers corresponding to the respective levels, where the alarm level 1 corresponds to the second timer T1 and the second counter N1, the alarm level 2 corresponds to the second timer T2 and the second counter N2, and the alarm level 3 corresponds to the second timer T3 and the second counter N3. The duration time of the three second timers has the following size relationship: t1> T2> T3. The magnitude relation of the upper counting limits of the three second counters is as follows: n1> N2> N3.

TABLE 4

TABLE 5

Further optionally, if different alarm levels in the plurality of alarm levels correspond to different sets of second timers and second counters, the first notification may further include second information, where the second information is used to indicate one alarm level in the plurality of alarm levels, so that the first device can quickly determine one alarm level according to the second information, and start a set of second timers and second counters corresponding to the one alarm level.

According to the scheme, the second counter is nested in the second timer, so that after the first notification about triggering the alarm is received for the first time, the first equipment can execute the alarm only after the first notification about triggering the alarm is continuously received for a certain time and the first notification is received for the preset times within the time, namely the positioning confidence coefficient stably does not meet the preset condition within the time. Therefore, the condition of false alarm can be effectively avoided, the alarm can be triggered within a certain time, the confidence coefficient of the positioning system can be ensured, and the reliability of the positioning system is improved. In addition, the scheme also configures different second timers and second counters aiming at different alarm levels, so that the alarm with higher confidence risk is executed more timely, the confidence of the positioning system can be further improved, and the user experience is improved.

Another control method for the positioning confidence according to the embodiment of the present application will be described below by taking the flowchart of fig. 6 as an example.

The method shown in fig. 6 may be applied to the communication system shown in fig. 1, and an execution subject of the method may be executed by any network element or entity or device in the communication system shown in fig. 1, such as an LMF or a terminal, as long as the network element or entity or device has a positioning calculation capability, which is not limited in the embodiment of the present application. For convenience of description, a network element or entity or device that will perform the method is exemplified below as the first device.

As shown in fig. 6, a control method for positioning confidence includes:

s601, the first device receives a first notice;

wherein the first notification includes location confidence related information that may be used to trigger an alert regarding location confidence. The specific implementation manner of this step may refer to the specific implementation manner of step S201 or S401 above, and is not described herein again.

And S602, the first device starts a third timer according to the first notification, and executes an alarm within the duration of the third timer or when the third timer expires.

Optionally, if the first device performs the alarm for the duration of the third timer, stopping the third timer; alternatively, the first device stops the third timer when the third timer expires. In this way, reliable operation of the positioning system can be ensured.

Illustratively, the relevant attribute of the third timer may be set as follows:

1) Start (Start): the first device receives a first notification triggering an alert for the first time. Wherein, the first receiving of the first notification may include the following: after a long period of idleness (i.e., a long period of non-receipt of the first notification), the first notification is received for the first time.

2) Stop (Stop): the third timer is stopped once the first device has performed the alarm.

3) Time expired (At expire): an alarm is executed.

The operation method of the third timer is described by two specific examples: and setting the duration of the third timer to be 5 slots, and the first device receives the first notification at slot0 for the first time. Referring to fig. 7A, if the first device performs an alarm for the duration of the third timer (e.g., performs an alarm at slot 3), the third timer is immediately stopped (even if it has not expired); referring to fig. 7B, if the first device does not alarm until the third timer expires, an alarm is performed at the expiration of the third timer. Therefore, the first equipment can be ensured to execute the alarm within a certain time, and the confidence coefficient of the positioning system is further ensured.

Optionally, the alarms in this embodiment may also be divided into multiple levels, and different alarm levels correspond to different third timers.

Further optionally, when different alarm levels correspond to different third timers, the duration of the third timer may be inversely related to the alarm level, that is, the higher the alarm level is, the higher the confidence risk is, and the shorter the expiration time of the third timer is, the shorter the first device may perform an alarm. Alternatively, the duration of the third timer may be positively correlated to the alert level, i.e. the lower the alert level, the higher the confidence risk, and the shorter the expiration time of the third timer, the shorter the time the first device will perform the alert.

Still taking the above three alarm levels as an example, table 6 shows the relevant attribute settings of the third timer corresponding to each level, where alarm level 1 corresponds to the third timer T1, alarm level 2 corresponds to the third timer T2, and alarm level 3 corresponds to the third timer T3. The magnitude relation of the duration of the three third timers is: t1> T2> T3.

TABLE 6

Further optionally, if different alarm levels in the multiple alarm levels correspond to different third timers, the first notification may further include third information, where the third information is used to indicate one alarm level in the multiple alarm levels, so that the first device can quickly determine one alarm level according to the third information and start the third timer corresponding to the one alarm level.

Further alternatively, in case of a tight resource of the third timer, different alarm levels may share one third timer, i.e. no distinction is made between alarm levels, such as the generic third timer shown in table 7.

TABLE 7

In the above scheme, if the first device does not perform an alarm in response to the first notification within a certain time period (the duration of the third timer) after receiving the first notification, the alarm is performed when the third timer expires, which can ensure that the first device performs the alarm within the specified time period, thereby ensuring the confidence of the positioning system. In addition, the scheme also configures different third timers aiming at different alarm levels, so that the alarm with higher confidence risk is executed more timely, the confidence of the positioning system can be further improved, and the user experience is improved.

Another control method for the positioning confidence according to the embodiment of the present application will be described below by taking the flowchart of fig. 8 as an example.

The method shown in fig. 8 may be applied to the communication system shown in fig. 1, and an execution subject of the method may be executed by any network element or entity or device in the communication system shown in fig. 1, such as an LMF or a terminal, as long as the network element or entity or device has a positioning calculation capability, which is not limited in the embodiment of the present application. For convenience of description, a network element or entity or device that will perform the method is exemplified below as the first device.

As shown in fig. 8, a control method for localization confidence includes:

s801, receiving a first notification by first equipment;

wherein the first notification includes location confidence related information that may be used to trigger an alert regarding the location confidence. The specific implementation manner of this step may refer to the specific implementation manner of step S201, S401, or S601 above, and is not described herein again.

And S802, the first device starts a third counter according to the first notice, and executes an alarm about the position reliability when or after the count value of the third counter reaches the upper limit of counting.

Specifically, after the third counter is started, the first notification is received one or more times in each of one or more consecutive third detection periods related to the positioning confidence, the count value of the third counter is increased by 1, otherwise, the third counter is reset until the count value of the third counter reaches the upper limit of the count. The third counter is reset if the first notification is not received again for at least one third detection period of one or more consecutive third detection periods, i.e. if the third counter starts counting, the third counter is reset whenever one third detection period does not receive the first notification. Therefore, the alarm can be initiated after the first notice is received in a plurality of continuous third detection periods, and the situations of false alarm and false alarm caused by the ping-pong effect are avoided.

Optionally, the second device resets the third counter when determining that the count value of the third counter reaches the upper limit of the count; or the second device resets the third counter after determining that the count value of the third counter reaches the upper limit of count; or the second device resets the third counter before performing the alarm after determining that the count value of the third counter reaches the upper limit of the count; alternatively, the second device resets the third counter after performing the alert and before the next time the first notification is received. In this way, reliable operation of the positioning system can be ensured.

It should be understood that the third counter may start counting from any number, such as 0, 1, 2, or 3, and the like, and the embodiments of the present application are not limited thereto. For convenience of description, the third counter following this document takes counting from 0 as an example. Similarly, the third counter may be reset in a manner of zero clearing, i.e. the value is 0 after reset, or in other manners, e.g. the value is 1, 2 or 3 after reset. For convenience of description, the reset of the third counter is performed by zero.

It should be understood that the third detection period may be a period for detecting whether the positioning confidence coefficient satisfies a preset condition, and may also be different from the period for detecting whether the positioning confidence coefficient satisfies the preset condition, and is not limited herein. The third detection period may be the same as the first detection period and the second detection period, or may be different from the first detection period and the second detection period, which is not limited herein. For convenience of description, the third detection period in the following text is taken as an example of a period for detecting whether the localization confidence satisfies the preset condition.

Illustratively, the associated attribute setting of the third counter is as follows:

1) Reset (Reset): the first device receives the first notification triggering the alarm for the first time, or the third counter reaches the upper counting limit, or the first notification is not received again in at least one third detection period in one or more continuous third detection periods. Wherein, the first receiving of the first notification may include the following: after a long idle time (i.e. a long time without receiving the first notification), the first notification is received for the first time.

2) Count plus 1 (included): after the third counter is started, the first notification is received once or more times in each of one or more consecutive third detection periods, and the count is incremented by 1 after each third detection period ends.

If the time difference between the time when the first notification is received at a certain time and the time when the first notification is received last time exceeds the duration of the third detection period (indicating that a long idle time has elapsed), the count value is not incremented by 1, but is reset.

3) Upper count value (When stopping max value): and executing the alarm.

The operation of the third counter is described below by way of a specific example: let the third detection period be 1 slot, and the upper limit of the count of the third counter be 5. Referring to fig. 9, the first device receives the first notification for the first time in slot0, starts the third counter to count from 0 (N = 0); slot1, receiving the first notification again, then count up by 1 (N = 1); slot2, if the first notification is received again, the count is increased by 1 (N = 2); slot3, receiving the first notification again, then count up by 1 (N = 3); slot4, receiving the first notification again, then count up by 1 (N = 4); slot5, if the first notification is received again, the count is increased by 1 (N = 5), and at this time, the count value reaches the upper limit, and the first device performs the alarm. Through the process, the first device can give an alarm only after receiving the first notification for multiple times continuously, so that the situation of false alarm can be avoided, and the confidence of the positioning system is further ensured.

Optionally, the alarm in this embodiment may also be divided into multiple levels, and different alarm levels correspond to different third counters.

Further optionally, when different alarm levels correspond to different third counters, the upper limit of the count of the third counter may be negatively correlated with the alarm level, that is, the higher the alarm level is, the higher the confidence risk is, the smaller the upper limit of the count of the third counter is, and the shorter the time for the first device to perform the alarm is. Alternatively, the upper count limit of the third counter may be positively correlated with the alarm level, i.e. the lower the alarm level, the higher the confidence risk, the smaller the upper count limit of the third counter, and the shorter the time the first device will perform the alarm.

Still taking the above three alarm levels as an example, table 8 shows the relevant attribute settings of the third counter corresponding to each level, where alarm level 1 corresponds to the third counter N1, alarm level 2 corresponds to the third counter N2, and alarm level 3 corresponds to the third counter N3. The magnitude relation of the upper limit of the counting of the three third counters is as follows: n1> N2> N3.

TABLE 8

Further optionally, if different alarm levels in the multiple alarm levels correspond to different third counters, the first notification may further include fourth information, where the fourth information is used to indicate one alarm level in the multiple alarm levels, so that the first device may quickly determine one alarm level according to the fourth information and start the third counter corresponding to the one alarm level to count.

Further alternatively, in case of resource shortage of the third counter, different alarm levels may also share one third counter, i.e. no distinction is made between alarm levels, such as the generic third counter shown in table 9.

TABLE 9

In the above scheme, the first device will only perform an alarm after receiving the first notification (reaching the upper limit of the count) for a plurality of times, so as to effectively avoid the situation of "false alarm" and further ensure the confidence of the positioning system. In addition, the scheme also configures different third counters for different alarm levels, so that the alarm with higher confidence risk is executed more timely, the confidence of the positioning system can be further improved, and the user experience is improved.
