Information transmission method and device, storage medium

Technical Field

The present disclosure relates to the field of communications, and in particular to an information transmission method and device, and a storage medium.

Background technique

In Release 17 (R17), in order to reduce positioning delay, a pre-configured measurement gap (MG) for positioning is introduced. The base station can pre-configure the MG for the terminal and activate it later as needed.

Detailed ways

Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

It should also be understood that the term "and/or" used herein refers to and includes any or all possible combinations of at least one associated listed item.

It should be understood that although the terms first, second, third, etc. may be used in the present disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present disclosure, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

In R17, the process of configuring the preconfigured measurement interval for the terminal by the base station may be shown in FIG. 1, and includes the following steps:

Step 0: The base station and LMF exchange transmission point (Transmission and Receiving Point, TRP) information.

Step 1. LMF sends a New Radio Positioning Protocol a measurement preconfiguration required (NRPPa measurement preconfiguration required) message to the base station, requesting the base station to configure the preconfigured measurement interval for the terminal.

Step 2: After receiving the request message, the base station sends a preconfigured measurement interval to the terminal through a Radio Resource Control (RRC) message.

The RRC message may be an RRC reconfiguration message.

Step 3: The terminal sends an RRC Reconfiguration Complete message to the base station.

Step 4: The base station sends an NRPPa measurement preconfiguration confirm message to the LMF.

In step 5a, the terminal sends a positioning measurement gap activation or deactivation request (Positioning Measurement Gap Activation/Deactivation) message to the base station.

In step 5b, LMF sends an NRPPa measurement activation (NRPPa Measurement Activation) or deactivation request message to the base station.

The above step 5a or step 5b is performed selectively, that is, the terminal or LMF may request the base station to activate or deactivate the preconfigured measurement interval.

Step 6: The base station sends a positioning measurement interval activation or deactivation message to the terminal.

It can be seen that both the terminal and the LMF can request the base station to activate (or deactivate) the preconfigured measurement interval, and then the base station sends an activation (or deactivation) message to the terminal to activate (or deactivate) the preconfigured measurement interval.

Since there are the above two schemes for requesting the base station to activate the preconfigured measurement interval, and the base station may optionally support the terminal to request activation or deactivation of the preconfigured measurement interval, if the base station does not support the terminal to request activation of the preconfigured measurement interval, the following problems will occur:

Problem 1: The terminal does not know that the base station does not support the terminal's request to activate the preconfigured measurement interval, so after the terminal sends a request message to the base station requesting activation of the preconfigured measurement interval, the base station cannot activate the preconfigured measurement interval.

Question 2: LMF does not know that the base station does not support the terminal's request to activate the preconfigured measurement interval, so LMF may think that the terminal will send the above request message to the base station to request the activation of the preconfigured measurement interval. Therefore, LMF will not send a request message to the base station to request the activation of the preconfigured measurement interval. This may result in the UE not requesting the activation of the preconfigured measurement interval, and LMF will no longer request the activation of the preconfigured measurement interval.

The above situations will cause the pre-configured MG to fail to be activated.

In order to solve the above technical problems, the present disclosure provides the following information transmission method and device, storage medium, to ensure that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

The information transmission method provided by the present disclosure is first introduced from the base station side.

The present disclosure provides an information transmission method, as shown in FIG. 2 , which is a flow chart of an information transmission method according to an embodiment, which can be performed by a base station. The method may include the following steps:

Step 201: In step 201, the base station sends indication information, where the indication information is used to indicate whether the base station supports receiving a first request message sent by a terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In an embodiment of the present disclosure, the base station may send the indication information to the opposite device, and inform the opposite device through the indication information whether the base station supports receiving the first request message sent by the terminal, wherein the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. It should be noted that the first request message is sent by the terminal to the base station.

In a possible implementation, the opposite device may be a terminal, and accordingly, the base station may send the indication information to the terminal to inform the terminal whether the base station supports receiving a first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The terminal may determine, based on the indication information, whether the terminal requests to activate or deactivate the preconfigured measurement interval.

In another possible implementation, the opposite device may be a core network device, such as LMF. Accordingly, the base station may send the indication information to the LMF to inform the LMF whether the base station supports receiving a first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The LMF may determine, based on the indication information, whether the LMF requests activation or deactivation of the preconfigured measurement interval.

In an embodiment of the present disclosure, the base station receives a first request message from the terminal, the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval, that is, the terminal requests the base station to activate or deactivate the preconfigured measurement interval through the first request message; or the base station may receive a third request message from the LMF, the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval, that is, the LMF requests the base station to activate or deactivate the preconfigured measurement interval through the third request message. After receiving the first request message or the third request message, the base station may send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval.

In one possible implementation, the base station may send the activation message or deactivation message to the terminal via a downlink media access control element (DL MAC CE).

It should be noted that in the present disclosure, the function of the third request message is similar to that of the first request message, both of which are used to request the base station to activate or deactivate the preconfigured measurement interval. The difference is that the third request message is sent by the LMF to the base station, and the first request message is sent by the terminal to the base station. In addition, the message format and content of the third request message are different from the message format and content of the first request message.

In one possible implementation, the indication information can be used to indicate at least one of the following: the base station supports the terminal to send the first request message; the base station allows the terminal to send the first request message; the base station does not support the terminal to send the first request message; the base station does not allow the terminal to send the first request message.

In one example, the indication information may be used to indicate that the base station supports the terminal to send the first request message, that is, the base station has the capability of supporting the terminal to request activation or deactivation of a preconfigured measurement interval.

In another example, the indication information may be used to indicate that the base station allows the terminal to send the first request message, that is, the base station has the capability of supporting the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station currently allows the terminal to send the first request message to the base station.

In another example, the indication information may be used to indicate that the base station does not support the terminal to send the first request message, that is, the base station does not have the ability to support the terminal to request activation or deactivation of a preconfigured measurement interval.

In another example, the indication information may be used to indicate that the base station does not allow the terminal to send the first request message. At this time, the terminal may determine, according to the indication information, that the base station temporarily or permanently does not allow the terminal to send the first request message.

In another example, the indication information can be used to indicate that the base station supports the terminal to send the first request message, and the base station allows the terminal to send the first request message. That is, the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station allows the terminal to send the first request message based on load, service requirements, etc.

Alternatively, the indication information may be used to indicate that the base station supports the terminal to send the first request message, and that the base station does not allow the terminal to send the first request message. That is, the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station temporarily does not allow the terminal to send the first request message based on load, service requirements, etc.

The above is only an exemplary description. In actual applications, the scheme in which the indication information is used to indicate whether the base station has the ability to support the terminal to request activation or deactivation of the pre-configured measurement interval should all fall within the protection scope of the present disclosure.

In a possible implementation manner, the preconfigured measurement interval is used at least for the terminal to perform positioning-related measurements.

Of course, the preconfigured measurement interval can also be used by the terminal to perform radio resource management (Radio Resource Management, RRM), etc., and the present disclosure does not limit this. In the above embodiment, the base station can send indication information, and the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval, that is, the base station can inform the opposite device whether the base station supports the terminal's request to activate or deactivate the preconfigured measurement interval, thereby ensuring the activation or deactivation of the preconfigured measurement interval, improving the accuracy and reliability of terminal positioning, and reducing positioning delay.

In some optional embodiments, the embodiments of the present disclosure provide an information transmission method, as shown in FIG. 3, which is a flow chart of an information transmission method according to an embodiment, which can be performed by a base station. The method may include the following steps:

Step 301: In step 301, the base station sends indication information to the terminal, where the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In an embodiment of the present disclosure, the base station may send the indication information to the terminal to inform the terminal whether the base station supports receiving a first request message sent by the terminal, the first request message being used to request the base station to activate or deactivate a preconfigured measurement interval, that is, the base station may inform the terminal through the indication information whether the base station supports the terminal requesting the base station to activate or deactivate the preconfigured measurement interval. The terminal may determine, based on the indication information, whether the terminal itself requests to activate or deactivate the preconfigured measurement interval.

In a possible implementation, in response to configuring the preconfigured measurement interval for the terminal, the base station sends the indication information to the terminal. Optionally, the base station may send the indication information to the terminal when configuring the preconfigured measurement interval for the terminal, and the indication information may be sent separately, may be sent together with the preconfigured measurement interval, or may be sent within a specified time range for configuring the preconfigured measurement interval, which is not limited in the present disclosure.

Of course, the preconfigured measurement interval may also be used for the terminal to perform RRM, etc., and the present disclosure does not limit this.

Step 302: In step 302, the base station receives the first request message sent by the terminal.

In the embodiment of the present disclosure, step 302 is an optional step.

If the indication information indicates that the base station supports receiving the first request message sent by the terminal, and the terminal determines that it requests to activate or deactivate the preconfigured measurement interval by itself, step 302 can be executed, and the base station can receive the first request message sent by the terminal.

In one example, the indication information indicates that the base station supports the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, step 302 can be executed, and the base station receives the first request message sent by the terminal.

Of course, step 302 may not be executed at this time, that is, the base station may receive a third request message sent by a core network device, such as LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

After receiving the first request message from the terminal or the third request message from the LMF, the base station can send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval.

Among them, the base station can send the activation message or deactivation message to the terminal through DL MAC CE.

In another example, the indication information indicates that the base station allows the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, step 302 can be executed, and the base station receives the first request message sent by the terminal.

Of course, step 302 may not be performed at this time, that is, the base station may receive a third request message sent by the LMF, wherein the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. The third request message is sent by a core network device, such as the LMF, to the base station.

In another example, the indication information indicates that the base station does not support the terminal sending the first request message, and step 302 may not be performed. That is, the base station will not receive the first request message sent by the terminal, and when the base station does not support the terminal sending the first request message, the signaling resource waste caused by the terminal still sending the first request message to the base station is avoided.

Alternatively, step 302 can still be executed, that is, the base station receives the first request message sent by the terminal, but the base station cannot activate or deactivate the preconfigured measurement interval based on the first request message.

In addition, the base station may receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. After receiving the third request message from the LMF, the base station may send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval. Among them, the base station may send the activation message or the deactivation message to the terminal via the DL MAC CE. Ensuring that the preconfigured measurement interval can be activated or deactivated improves the accuracy and reliability of terminal positioning and reduces positioning delay.

In another example, if the indication information indicates that the base station does not allow the terminal to send the first request message, step 302 cannot be performed. That is, the base station will not receive the first request message sent by the terminal, avoiding signaling resource waste caused by the terminal still sending the first request message to the base station.

In another example, the indication information indicates that the base station supports the terminal to send the first request message, and the base station allows the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, step 302 can be executed, and the base station receives the first request message sent by the terminal.

Of course, step 302 may not be performed at this time, that is, the base station may receive a third request message sent by the LMF, and the third request message is used by the base station to activate or deactivate the preconfigured measurement interval.

In another example, the indication information indicates that the base station supports the terminal to send the first request message, and the base station does not allow the terminal to send the first request message, then step 302 cannot be performed. That is, the base station will not receive the first request message sent by the terminal, avoiding the waste of signaling resources caused by the terminal still sending the first request message to the base station.

In addition, the base station can receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. After receiving the third request message from the LMF, the base station can send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval. Among them, the base station can send the activation message or the deactivation message to the terminal through the DL MAC CE. It is ensured that the preconfigured measurement interval can be activated or deactivated, which improves the accuracy and reliability of terminal positioning and reduces the positioning delay. In a possible implementation method, the base station can receive a first request message sent by the terminal through a first message. Among them, the first message can be an uplink media access control element (UpLink Media Access Control Element, UL MAC CE).

In the above embodiment, the base station can inform the terminal whether the base station supports the terminal's request to activate or deactivate the preconfigured measurement interval, ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

In some optional embodiments, the present disclosure provides an information transmission method, as shown in FIG. 4 , which is a flow chart of an information transmission method according to an embodiment, which can be performed by a base station. The method may include the following steps:

Step 401: In step 401, the base station sends indication information to the LMF, where the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In an embodiment of the present disclosure, the base station may send the indication information to a core network device, such as LMF, to inform the LMF whether the base station supports receiving a first request message sent by a terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The LMF may determine, based on the indication information, whether the LMF requests activation or deactivation of the preconfigured measurement interval.

In a possible implementation, the base station may send the indication information to the LMF via a first NRPPa message.

In one example, the first NRPPa message may be any one of the following: a measurement preconfiguration confirmation (MEASUREMENT PRECONFIGURATION CONFIRM) message; a transmission point information response (TRP INFORMATION RESPONSE) message; or other NRPPa messages.

The other NRPPa messages here are other NRPPa messages except the measurement pre-configuration confirmation message and the transmission point information response message.

Step 402: In step 402, the base station sends a second request message to the LMF, where the second request message is used to request the LMF to send a third request message.

Specifically, the base station may send a second request message to a core network device, such as LMF. In response to receiving the second request message, the LMF may send a third request message to the base station.

In the embodiment of the present disclosure, step 402 is optional.

In one possible implementation, if the indication information indicates that the base station does not support and/or does not allow the terminal to request activation or deactivation of the preconfigured measurement interval, step 402 can be executed, and the base station sends a second request message to the LMF, requesting the LMF to send a third request message to the base station to request the base station to activate or deactivate the preconfigured measurement interval.

In another possible implementation, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 402 may not be performed, that is, the terminal may send a first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another possible implementation, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 402 may be performed, that is, at this time, the base station may send a second request message to the LMF, requesting the LMF to send a third request message to the base station, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Accordingly, the terminal may no longer send the first request message to the base station.

In another possible implementation, regardless of the content of the indication information, step 402 may be performed, that is, the default base station does not support or allow the terminal to request activation or deactivation of the preconfigured measurement interval. At this time, the base station may send a second request message to the LMF, requesting the LMF to send a third request message to the base station, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Accordingly, the terminal may no longer send the first request message to the base station.

In another possible implementation, step 401 may not be performed, and step 402 may be performed directly. Accordingly, the subsequent step 403 may be performed directly, that is, the LMF directly sends a third request message to the base station according to the second request information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. The base station replaces the indication information with the second request message. When the LMF receives the second request message, it can be determined that the base station does not support or allow the terminal to send the first request message. Therefore, the LMF can send a third request message to the base station according to the second request message.

It should be noted that the third request message has a similar function to the first request message, both of which are used to request the base station to activate or deactivate the preconfigured measurement interval. The difference is that the third request message is sent by the LMF to the base station, and the first request message is sent by the terminal to the base station. In addition, the message format and content of the third request message are different from the message format and content of the first request message.

In a possible implementation, the base station may send the second request message to the LMF via a first NRPPa message.

That is, the base station can send the indication information and the second request message together to the LMF through the first NRPPa message.

Exemplarily, the indication information is used to indicate that the base station does not support the terminal sending the first request message, that is, the base station does not have the ability to support the terminal's request to activate or deactivate the preconfigured measurement interval. In order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, the base station can execute step 402, send a second request message to the LMF, requesting the LMF to send the third request message, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, the base station may not execute step 402, and the LMF may send a third request message to the base station according to the content of the indication information, and the base station may directly receive it.

Exemplarily, the indication information is used to indicate that the base station does not allow the terminal to send the first request message. In order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, the base station can execute step 402, send a second request message to the LMF, and request the LMF to send a third request message. The third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Exemplarily, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, the base station may also execute step 402, send a second request message to the LMF, requesting the LMF to send a third request message, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, step 402 may not be performed, and the terminal sends the first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. That is, the terminal may request to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, step 402 may not be executed, and the LMF may send a third request message to the base station according to the content of the indication information, and the base station may directly receive it.

Exemplarily, the indication information is used to indicate that the base station supports the terminal to send the first request message, and when the base station temporarily does not allow the terminal to send the first request message, the base station may also execute step 402, send a second request message to the LMF, and request the LMF to send a third request message, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports the terminal to send the first request message, and the base station temporarily does not allow the terminal to send the first request message, the base station may not perform step 402, and the terminal sends the first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. That is, the terminal may request to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports the terminal to send the first request message, and the base station temporarily does not allow the terminal to send the first request message, step 402 can be omitted, and the LMF sends a third request message to the base station according to the content of the indication information, and the base station directly receives it.

Step 403: In step 403, the base station receives the third request message sent by the LMF.

In the embodiment of the present disclosure, step 403 is optional.

In a possible implementation manner, if the indication information indicates that the base station does not support and/or does not allow the terminal to request activation or deactivation of the preconfigured measurement interval, step 403 may be performed.

If the base station sends a second request message to the LMF, step 403 may specifically include:

If the base station does not send the second request message to the LMF, step 403 may specifically include:

Receive the third request message sent by the LMF to the base station according to the indication information.

In another possible implementation manner, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 403 may be performed.

If the base station sends a second request message to the LMF, step 403 may specifically be:

In another possible implementation, if the base station does not send the indication information, the base station executes step 402, sends a second request message to the LMF, the LMF sends a third request message to the base station according to the second request message, and the base station executes step 403, receives the third request message sent by the LMF. In another possible implementation, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 403 may not be executed.

Accordingly, the base station can receive the first request message sent by the terminal, and the LMF does not need to send a third request message to the base station.

In another possible implementation manner, if the indication information indicates that the base station supports the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station temporarily does not allow the terminal to send the first request message, step 403 may be executed.

In the above manner, after receiving the first request message from the terminal or the third request message from the LMF, the base station can send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval.

In the above embodiment, the base station can inform the LMF whether the base station supports the terminal's request to activate or deactivate the preconfigured measurement interval, ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

In some optional embodiments, the embodiments of the present disclosure provide an information transmission method, as shown in FIG. 5, which is a flow chart of an information transmission method according to an embodiment, which can be performed by a base station. The method may include the following steps:

Step 501: In step 501, the base station receives a fourth request message sent by the LMF, and the fourth request message is used to request the base station to send indication information.

In an embodiment of the present disclosure, the LMF may actively send a fourth request message to the base station, and request the base station to send indication information to the LMF through the fourth request message, wherein the indication information is used to indicate whether the base station supports receiving the first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In a possible implementation, the base station may receive the fourth request message sent by the LMF through the second NRPPa message.

In one example, the second NRPPa message may be any one of the following: a measurement preconfiguration request (MEASUREMENT PRECONFIGURATION REQUIRED) message; a transmission point information request (TRP INFORMATION REQUEST) message; or other NRPPa messages.

The other NRPPa messages here are other NRPPa messages except the measurement pre-configuration request message and the transmission point information request message.

Step 502: In the step 502, the base station sends the indication information to the LMF based on the fourth request message.

In an embodiment of the present disclosure, the base station may send the indication information to the LMF based on the request of the LMF, informing the LMF whether the base station supports receiving a first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The LMF may determine whether the LMF requests to activate or deactivate the preconfigured measurement interval based on the indication information.

In one example, the LMF sends a fourth request message to the base station through a second NRPPa message, which is a measurement preconfiguration request message. Accordingly, the base station can send the indication information to the LMF through a first NRPPa message, which is a measurement preconfiguration confirmation message.

In another example, LMF sends a fourth request message to the base station through a second NRPPa message, which is a transmission point information request message. Accordingly, the base station can send the indication information to LMF through a first NRPPa message, which is a transmission point information response message.

In another example, LMF sends a fourth request message to the base station through a second NRPPa message, where the second NRPPa message is a second NRPPa message other than the measurement preconfiguration request message and the transmission point information request message. Accordingly, the base station can send the indication information to LMF through a first NRPPa message, where the first NRPPa message is a second NRPPa message other than the measurement preconfiguration confirmation message and the transmission point information response message and is used to respond to the second NRPPa message.

The above is only an exemplary description. The scheme in which the base station receives the fourth request message through the second NRPPa message and sends the indication information to the LMF through the first NRPPa message based on the fourth request message should fall within the protection scope of the present disclosure.

In another example, the indication information may be used to indicate that the base station allows the terminal to send the first request message, that is, the base station has the capability of supporting the terminal to request activation or deactivation of a preconfigured measurement interval, and the base station currently allows the terminal to send the first request message to the base station.

Step 503: In step 503, the base station sends a second request message to the LMF, where the second request message is used to request the LMF to send a third request message.

In the embodiment of the present disclosure, step 503 is optional. The implementation of step 503 is similar to step 402, and will not be described in detail here.

Step 504: In step 504, the base station receives the third request message sent by the LMF based on the second request message.

In the embodiment of the present disclosure, step 504 is optional. The implementation of step 504 is similar to step 403, and will not be described in detail here.

In the above embodiment, the base station can receive the fourth request message sent by the LMF, and send indication information to the LMF based on the fourth request message, ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

In some optional embodiments, the embodiments of the present disclosure provide an information transmission method, as shown in FIG. 6, which is a flow chart of an information transmission method according to an embodiment, which can be performed by a base station. The method may include the following steps:

Step 601: In step 601, the base station sends indication information to the terminal.

The indication information is used to indicate whether the base station supports receiving a first request message sent by a terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

The implementation of step 601 is similar to that of step 301 and will not be described in detail here.

Step 602: In step 602, the base station receives the first request message sent by the terminal.

In the embodiment of the present disclosure, step 602 is an optional step, and the specific implementation is similar to the above step 302, which will not be described in detail here.

Step 603: In step 603, the base station sends the indication information to the LMF.

In an embodiment of the present disclosure, the base station may send the indication information to the LMF based on a core network device, such as a fourth request message sent by the LMF. The specific implementation method is similar to the above steps 501 to 502 and will not be repeated here.

Alternatively, the base station may directly send the indication information to the LMF. The specific implementation is similar to the above step 401 and will not be described in detail here.

Step 604: In step 604, the base station sends a second request message to the LMF, where the second request message is used to request the LMF to send a third request message.

In the embodiment of the present disclosure, step 604 is optional. The implementation of step 604 is similar to step 402 and will not be described in detail here. In the embodiment of the present disclosure, the above step 603 is optional, and the base station directly performs step 604, that is, the base station replaces the indication information with the second request message. The specific implementation method has been introduced in the above embodiment and will not be described in detail here.

Step 605: In step 605, the base station receives the third request message sent by the LMF.

In the embodiment of the present disclosure, step 605 is optional. The implementation of step 605 is similar to step 403 and will not be described in detail here.

It should also be noted that step 602 and step 605 can be performed selectively, that is, the base station can receive the first request message sent by the terminal, and send an activation message or a deactivation message to the terminal based on the first request message, thereby activating or deactivating the preconfigured measurement interval. Alternatively, the base station can receive the third request message sent by the LMF, and send an activation message or a deactivation message to the terminal based on the third request message, thereby activating or deactivating the preconfigured measurement interval.

In one possible implementation, the base station may send the activation message or deactivation message to the terminal via DL MAC CE.

In the above embodiment, the base station can send indication information to the terminal and LMF to inform the terminal and LMF whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval, thereby ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

The following is an introduction to the information transmission method provided by the present disclosure from the terminal side.

The present disclosure provides an information transmission method, as shown in FIG. 7 , which is a flow chart of an information transmission method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

Step 701: In step 701, the terminal receives indication information sent by the base station, and the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In an embodiment of the present disclosure, a terminal may receive the indication information sent by a base station, and the indication information is used to inform the terminal whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The terminal may determine, based on the indication information, whether the terminal itself requests to activate or deactivate the preconfigured measurement interval.

In a possible implementation manner, the terminal receives the indication information sent by the base station to the terminal in response to configuring the preconfigured measurement interval for the terminal.

In the above embodiment, the terminal can receive the indication information sent by the base station, so as to determine whether the base station supports the terminal's request to activate or deactivate the preconfigured measurement interval, thereby ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of the terminal positioning and reducing the positioning delay.

In some optional embodiments, the present disclosure provides an information transmission method, as shown in FIG8 , which is a flow chart of an information transmission method according to an embodiment, which can be executed by a terminal, and the method may include the following steps:

Step 801: In step 801, the terminal receives indication information sent by the base station, and the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

The specific implementation method is similar to the above step 701 and will not be repeated here.

Step 802: In step 802, if the indication information indicates that the base station supports receiving the first request message sent by the terminal, the terminal sends the first request message to the base station.

In the embodiment of the present disclosure, step 802 is an optional step.

In one example, the indication information indicates that the base station supports the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, the terminal can execute step 802 to send the first request message to the base station.

Of course, step 802 may not be performed at this time, that is, the base station may receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

After receiving the first request message from the terminal or the third request message from the LMF, the base station can send an activation message or a deactivation message to the terminal. The terminal activates or deactivates the preconfigured measurement interval based on the received activation message or deactivation message.

In another example, the indication information indicates that the base station allows the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, step 302 can be executed to send the first request message to the base station.

Of course, step 302 may not be performed at this time, that is, the base station may receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another example, if the indication information indicates that the base station does not support the terminal sending the first request message, step 802 may not be performed. That is, the terminal will not send the first request message to the base station, and when the base station does not support the terminal sending the first request message, the signaling resource waste caused by the terminal still sending the first request message to the base station is avoided.

Alternatively, the terminal may still execute step 802 to send the first request message to the base station, but the base station cannot activate or deactivate the preconfigured measurement interval based on the first request message.

In addition, the base station may receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. After receiving the third request message from the LMF, the base station may send an activation message or a deactivation message to the terminal, and the terminal activates or deactivates the preconfigured measurement interval based on the received activation message or deactivation message. Among them, the base station may send the activation message or the deactivation message to the terminal via the DL MAC CE. Ensuring that the preconfigured measurement interval can be activated or deactivated improves the accuracy and reliability of terminal positioning and reduces positioning delay.

In another example, the indication information indicates that the base station does not allow the terminal to send the first request message, and step 802 cannot be performed. That is, the terminal will not send the first request message to the base station, avoiding waste of terminal signaling resources.

In another example, the indication information indicates that the base station supports the terminal to send the first request message, and the base station allows the terminal to send the first request message. The terminal can determine whether to request to activate or deactivate the preconfigured measurement interval by itself based on the indication information. Further, step 802 can be executed to send the first request message to the base station.

After receiving the first request message from the terminal or the third request message from the LMF, the base station may send an activation message or a deactivation message to the terminal, and the terminal activates or deactivates the preconfigured measurement interval based on the received activation message or deactivation message. The base station may send the activation message or the deactivation message to the terminal via the DL MAC CE.

In another example, the indication information indicates that the base station supports the terminal to send the first request message, and the base station does not allow the terminal to send the first request message, then step 802 cannot be performed. That is, the terminal will not send the first request message to the base station, avoiding the waste of signaling resources caused by the terminal still sending the first request message to the base station.

In addition, the base station may receive a third request message sent by the LMF, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. After receiving the third request message from the LMF, the base station may send an activation message or a deactivation message to the terminal, and the terminal activates or deactivates the preconfigured measurement interval based on the received activation message or deactivation message. Among them, the base station may send the activation message or the deactivation message to the terminal via the DL MAC CE. Ensuring that the preconfigured measurement interval can be activated or deactivated improves the accuracy and reliability of terminal positioning and reduces positioning delay. In a possible implementation, the terminal may send a first request message to the base station via a first message. Among them, the first message may be a UL MAC CE.

After the terminal sends the first request message to the base station, the terminal may receive an activation message or a deactivation message sent by the base station, and the terminal activates or deactivates the preconfigured measurement interval based on the received activation message or deactivation message.

Next, the information transmission method provided by the present disclosure will be introduced from the LMF side.

The present disclosure provides an information transmission method, as shown in FIG. 9, which is a flow chart of an information transmission method according to an embodiment, which may be performed by a core network device, such as an LMF. The method may include the following steps:

Step 901: In step 901, the LMF receives indication information sent by the base station, and the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

In the embodiment of the present disclosure, the base station may configure a preconfigured measurement interval for the terminal. The process of the base station configuring the preconfigured measurement interval for the terminal is similar to steps 0 to 4 shown in FIG. 1 above, and will not be repeated here. Optionally, the preconfigured measurement interval is at least used for the terminal to perform positioning-related measurements.

Before activating or deactivating the preconfigured measurement interval, step 901 may be performed, where a core network device, such as an LMF, receives the indication information sent by the base station.

In the embodiment of the present disclosure, the indication information is used to inform the LMF whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. The LMF can determine whether the LMF requests to activate or deactivate the preconfigured measurement interval based on the indication information.

In an example, the first NRPPa message may be any one of the following: a measurement pre-configuration confirmation message; a transmission point information response message; or other NRPPa messages.

In one example, the indication information may be used to indicate that the base station supports the terminal to send the first request message. That is, the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval. At this time, the LMF may not send the third request message to the base station according to the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Of course, at this time, the LMF may also send the third request message to the base station according to the indication information, and the present disclosure is not limited to this.

In another example, the indication information can be used to indicate that the base station allows the terminal to send the first request message. That is, the base station has the ability to support the terminal's request to activate or deactivate the preconfigured measurement interval, and the base station currently allows the terminal to send the first request message to the base station. At this time, the LMF may not send a third request message to the base station according to the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Of course, at this time, the LMF may also send the third request message to the base station according to the indication information, and the present disclosure is not limited to this.

In another example, the indication information may be used to indicate that the base station does not support the terminal to send the first request message. That is, the base station does not have the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval. At this time, the LMF may send the third request message to the base station according to the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another example, the indication information may be used to indicate that the base station does not allow the terminal to send the first request message. At this time, the terminal may determine, based on the indication information, that the base station temporarily or permanently does not allow the terminal to send the first request message. At this time, the LMF may send the third request message to the base station based on the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another example, the indication information can be used to indicate that the base station supports the terminal to send the first request message, and the base station allows the terminal to send the first request message. That is, the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station allows the terminal to send the first request message based on load, business requirements, etc. At this time, the LMF can send or not send the third request message to the base station according to the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, the indication information may be used to indicate that the base station supports the terminal to send the first request message, and that the base station does not allow the terminal to send the first request message. That is, the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station temporarily does not allow the terminal to send the first request message based on load, service requirements, etc. At this time, the LMF may send the third request message to the base station according to the indication information, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In the above embodiment, LMF can receive indication information sent by the base station, so as to determine whether the base station supports the activation or deactivation of the preconfigured measurement interval by the terminal, thereby ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

In some optional embodiments, the embodiments of the present disclosure provide an information transmission method, as shown in FIG. 10, which is a flow chart of an information transmission method according to an embodiment, which can be performed by a core network device, such as LMF, and the method may include the following steps:

Step 1001: In step 1001, the LMF receives indication information sent by a base station, where the indication information is used to indicate whether the base station supports receiving a first request message sent by a terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

The implementation of step 1001 is similar to that of step 901 above, and will not be repeated here.

Step 1002: In step 1002, the LMF receives a second request message sent by the base station, where the second request message is used to request the LMF to send a third request message.

In the embodiment of the present disclosure, step 1002 is optional.

In one possible implementation, if the indication information indicates that the base station does not support and/or does not allow the terminal to request activation or deactivation of the preconfigured measurement interval, step 402 can be executed to receive a second request message sent by the base station, where the second request message is used to request the LMF to send a third request message to the base station, where the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another possible implementation, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 1002 may not be performed, that is, the terminal may send a first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

In another possible implementation, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 402 may be performed, that is, the LMF may receive a second request message sent by the base station, the second request message is used to request the LMF to send a third request message to the base station, the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Accordingly, the terminal may no longer send the first request message to the base station.

In another possible implementation, regardless of the content of the indication information, step 1002 may be performed, that is, the default base station does not support or allow the terminal to request activation or deactivation of the preconfigured measurement interval, and the LMF may receive a second request message sent by the base station, the second request message is used to request the LMF to send a third request message to the base station, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval. Accordingly, the terminal may no longer send the first request message to the base station.

In another possible implementation, the above-mentioned step 1001 may not be executed, and step 1002 may be executed directly. Accordingly, the subsequent step 1003 may continue to be executed, that is, the LMF will not receive the indication information sent by the base station. When the LMF receives the second request message sent by the base station, it is determined that the base station replaces the indication information with the second request message, and determines that the base station does not support or does not allow the terminal to send the first request message. At this time, the LMF can directly send a third request message to the base station based on the second request message.

In a possible implementation, the LMF may receive the second request message sent by the base station via the first NRPPa message.

That is to say, the LMF can receive the indication information and the second request message sent by the base station through the first NRPPa message.

Exemplarily, the indication information is used to indicate that the base station does not support the terminal sending the first request message, that is, the base station does not have the ability to support the terminal's request to activate or deactivate the preconfigured measurement interval. In order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, step 1002 can be executed to receive the second request message sent by the base station. The second request message is used to request the LMF to send the third request message to the base station. The third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, step 1002 may not be executed, and the LMF may send a third request message to the base station according to the content of the indication information, and the base station may directly receive it.

Exemplarily, the indication information is used to indicate that the base station does not allow the terminal to send the first request message. In order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, step 402 can be executed, and the LMF receives the second request message sent by the base station. The second request message is used to request the LMF to send a third request message to the base station. The third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Exemplarily, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, step 1002 can also be executed, and the LMF receives a second request message sent by the base station, and the second request message is used to request the LMF to send a third request message to the base station, and the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, step 1002 may not be performed, and the terminal sends the first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. That is, the terminal may request to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports and/or allows the terminal to send the first request message, step 1002 may not be executed, and the LMF may send a third request message to the base station based on the content of the indication information, and the base station may directly receive it.

Exemplarily, the indication information is used to indicate that the base station supports the terminal to send the first request message, and the base station temporarily does not allow the terminal to send the first request message. Step 1002 can also be executed, and the LMF receives a second request message sent by the base station. The second request message is used to request the LMF to send a third request message to the base station. The third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports the terminal to send the first request message, and the base station temporarily does not allow the terminal to send the first request message, step 1002 may not be performed, and the terminal sends the first request message to the base station, and the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. That is, the terminal may request to activate or deactivate the preconfigured measurement interval.

Alternatively, when the indication information is used to indicate that the base station supports the terminal to send the first request message, and the base station temporarily does not allow the terminal to send the first request message, step 1002 can be omitted, and the LMF sends a third request message to the base station according to the content of the indication information, and the base station directly receives it.

Step 1003: In step 1003, the LMF sends the third request message to the base station.

In the embodiment of the present disclosure, step 1003 is optional.

In a possible implementation manner, if the indication information indicates that the base station does not support and/or does not allow the terminal to request activation or deactivation of the preconfigured measurement interval, step 1003 may be performed.

If the base station sends a second request message to the LMF, step 1003 may specifically include:

The third request message is sent to the base station based on the second request message.

If the base station does not send the second request message to the LMF, step 1003 may specifically include:

Send the third request message to the base station according to the indication information.

In another possible implementation manner, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 1003 may be performed.

In another possible implementation, if the LMF does not receive the indication information sent by the base station, it executes step 1002 to receive the second request message sent by the base station. The LMF sends a third request message to the base station based on the second request message, and executes step 1003 to send a third request message to the base station.

In another possible implementation manner, if the indication information indicates that the base station supports and/or allows the terminal to request activation or deactivation of the preconfigured measurement interval, step 1003 may not be performed.

In another possible implementation manner, if the indication information indicates that the base station supports the terminal to request activation or deactivation of the preconfigured measurement interval, and the base station temporarily does not allow the terminal to send the first request message, step 1003 may be executed.

After receiving the third request message from the LMF in the above manner, the base station can send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval.

In some optional embodiments, the embodiments of the present disclosure provide an information transmission method, as shown in FIG. 11, which is a flow chart of an information transmission method according to an embodiment, which can be performed by a core network device, such as LMF, and the method can include the following steps:

Step 1101: In step 1101, LMF sends a fourth request message to the base station, and the fourth request message is used to request the base station to send indication information.

In a possible implementation, the LMF may send the fourth request message to the base station via a second NRPPa message.

In an example, the second NRPPa message may be any one of the following: a measurement preconfiguration request message; a transmission point information request message; or other NRPPa messages.

Step 1102: In step 1102, the LMF receives the indication information sent by the base station based on the fourth request message.

In one possible implementation, the LMF may receive the indication information sent by the base station via the first NRPPa message.

In one example, the LMF may send a fourth request message to the base station through a second NRPPa message, where the second NRPPa message is a measurement preconfiguration request message. Accordingly, the base station may send the indication information to the LMF through a first NRPPa message, where the first NRPPa message is a measurement preconfiguration confirmation message.

The above is only an exemplary description. The schemes in which the LMF sends the fourth request message to the base station through the second NRPPa message, and receives the indication information sent by the base station through the first NRPPa message based on the fourth request message, should all fall within the scope of protection of the present disclosure.

The above is only an exemplary description. In actual applications, the scheme in which the indication information is used to indicate whether the base station has the ability to support the terminal to request activation or deactivation of the preconfigured measurement interval should fall within the scope of protection of this disclosure.

Step 1103: In step 1103, the LMF receives the indication information sent by the base station based on the fourth request message.

In the embodiment of the present disclosure, step 1103 is optional. The implementation of step 1103 is similar to step 1002, and will not be described in detail here.

Step 1104: In step 1104, the LMF receives the indication information sent by the base station based on the fourth request message.

In the embodiment of the present disclosure, step 1104 is optional. The implementation of step 1104 is similar to step 1003 and will not be described in detail here.

In the above embodiment, the LMF can send a fourth request message to the base station and receive indication information sent by the base station to the LMF based on the fourth request message, ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

In some optional embodiments, the present disclosure provides an information transmission method, as shown in FIG. 12 , which is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

Step 1201: In step 1201, the base station sends indication information to the terminal.

In the embodiment of the present disclosure, the implementation of step 1201 is similar to that of step 301 and will not be repeated here.

Step 1202: In step 1202, LMF sends a fourth request message to the base station, and the fourth request message is used to request the base station to send indication information.

In the embodiment of the present disclosure, the implementation of step 1202 is similar to that of step 1101 and will not be repeated here.

Step 1203: In step 1203, the base station sends the indication information to the core network device based on the fourth request message.

In the embodiment of the present disclosure, the implementation of step 1203 is similar to that of step 602 and will not be repeated here.

In the disclosed embodiment, step 1203 may not be performed, that is, the base station does not send the indication information to the core network device, such as LMF, and the base station may send the second request message to the LMF according to the fourth request message, requesting the LMF to send the third request message to the base station. That is, the base station replaces the indication information with the second request message.

Step 1204a: In step 1204a, the terminal sends a first request message to the base station.

In the embodiment of the present disclosure, the implementation of step 1204a is similar to step 802 and will not be repeated here.

Step 1204b: In step 1204b, the LMF sends a third request message to the base station.

In the embodiment of the present disclosure, the implementation of step 1204b is similar to step 1003 and will not be repeated here.

Of course, the core network device, such as LMF, can also send a third request message to the base station based on the second request message sent by the base station. The specific implementation method is similar to the above steps 1002 to 1003 and will not be repeated here.

Among them, step 1204a and step 1204b can be performed selectively, that is, the base station receives the first request message sent by the terminal, or receives the third request message sent by the LMF.

Step 1205: In step 1205, the base station sends an activation message or a deactivation message to the terminal.

In the disclosed embodiment, the base station may send the activation message or deactivation message to the terminal via DL MAC CE, thereby activating or deactivating the preconfigured measurement interval.

In the above embodiment, the base station may send indication information, and the indication information is used to indicate whether the base station supports receiving a first request message sent by the terminal, and the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval. That is, the base station may inform the terminal and LMF whether the base station supports the terminal's request to activate or deactivate the preconfigured measurement interval, thereby ensuring that the preconfigured measurement interval can be activated or deactivated, thereby improving the accuracy and reliability of terminal positioning and reducing positioning delay.

It is understandable that in the above embodiment, LMF is used as an example to introduce the information transmission steps performed by the core network device. In practical applications, the process of using other core network devices to perform the above solution also belongs to the protection scope of this disclosure.
