Technical Field

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

Background

In Release 17 (R17), a preconfigured Measurement Gap (MG) for positioning is introduced in order to reduce positioning delay. The base station may pre-configure the MG for the terminal and then activate it as needed.

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure.

In R17, the process of configuring the preconfigured measurement interval for the terminal by the base station may refer to fig. 1, and includes the following steps:

And step 0, performing Transmission AND RECEIVING Point (TRP) information interaction between the base station and the LMF.

And step 1, the LMF sends a measurement pre-configuration request (New Radio Positioning Protocol a measurement preconfiguration required,NRPPa measurement preconfiguration required) message of the new air interface positioning protocol A to the base station to request the base station to configure the pre-configured 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 (Radio Resource Control, RRC) message.

Wherein the RRC message may be an RRC reconfiguration (RRC Reconfiguration) message

And 3, the terminal feeds back an RRC reconfiguration complete (RRC Reconfiguration Complete) message to the base station.

Step 4, the base station sends NRPPa a measurement pre-configuration acknowledgement (NRPPa measurement preconfiguration confirm) message to the LMF.

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

Step 5b, a NRPPa measurement activation (NRPPa Measurement Activation) or deactivation request message is sent by the LMF to the base station.

The step 5a or the step 5b is alternatively performed. I.e. the terminal or LMF may request the base station to activate or deactivate the preconfigured measurement interval.

And 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 may request the base station to activate (or deactivate) the pre-configured measurement interval, and then the base station sends an activate (or deactivate) message to the terminal to activate (or deactivate) the pre-configured 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 be an option to support the terminal to request to activate or deactivate the preconfigured measurement interval, if the base station does not support the terminal to request to activate the preconfigured measurement interval, the following problem may exist:

a first problem is that the terminal does not know that the base station does not support the activation of the preconfigured measurement interval requested by the terminal, so that the base station cannot activate the preconfigured measurement interval after the terminal sends a request message for requesting to activate the preconfigured measurement interval to the base station.

Problem two, the LMF is unaware that the base station does not support the activation of the preconfigured measurement interval requested by the terminal, so the LMF may request the activation of the preconfigured measurement interval for the terminal to be considered to send the above request message to the base station, and thus the LMF may not send the request message to the base station to request the activation of the preconfigured measurement interval, which may result in that the LMF may not request the activation of the preconfigured measurement interval again in case the UE does not request the activation of the preconfigured measurement interval.

Both of the above cases may result in the preconfigured MG not being activated.

In order to solve the technical problems, the present disclosure provides the following information transmission method and apparatus, and a storage medium, which ensure that a preconfigured measurement interval can be activated or deactivated, improve accuracy and reliability of terminal positioning, and reduce positioning delay.

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

An embodiment of the present disclosure provides an information transmission method, referring to fig. 2, fig. 2 is a flowchart of an information transmission method, which may be performed by a base station, according to an embodiment, and the method may include the following steps:

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

In the embodiment of the disclosure, the base station may send the indication information to the opposite terminal device, and inform the opposite terminal device whether the base station supports the first request message sent by the receiving terminal, where the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. The first request message is sent from the terminal to the base station.

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

In another possible implementation manner, the peer device may be a core network device, such as an LMF, and accordingly, the base station may send the indication information to the LMF, informing the LMF whether the base station supports the first request message sent by the receiving terminal, where the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. The LMF may determine whether to activate or deactivate the preconfigured measurement interval requested by the LMF based on the indication information.

In the embodiment of the disclosure, a base station receives a first request message from a terminal, wherein the first request message is used for requesting the base station to activate or deactivate a preconfigured measurement interval, i.e. 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 requesting the base station to activate or deactivate the pre-configured measurement interval, i.e., the LMF requests the base station to activate or deactivate the pre-configured measurement interval through the third request message. The base station may transmit an activation message or a deactivation message to the terminal after receiving the first request message or 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 the deactivation message to the terminal through a DownLink media access Control Element (DL MAC CE).

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

In one possible implementation, the indication information may be used to indicate at least one of: 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, indication information may be used to instruct the base station to support the terminal to send the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal.

In another example, the indication information may be used to instruct a base station to allow the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement interval requested by the terminal and the base station currently allows the terminal to send this first request message to the base station.

In another example, indication information may be used to indicate that the base station does not support the terminal to send the first request message. I.e. the base station does not have the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal.

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

In another example, the indication information may be used to instruct a base station to support the terminal to transmit the first request message, and the base station allows the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal, while the base station allows the terminal to send the first request message based on load, traffic demand etc.

Or the indication information may be used to indicate that the base station supports the terminal to transmit the first request message, and that the base station does not allow the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal, while the base station temporarily does not allow the terminal to send the first request message based on load, traffic demand etc.

The foregoing is merely exemplary, and in practical applications, the scheme of indicating whether the base station has the capability of supporting the terminal to request to activate or deactivate the preconfigured measurement interval by using the indication information should all belong to the protection scope of the present disclosure.

In one possible implementation, the preconfigured measurement intervals are at least used for positioning-related measurements by the terminal.

Of course, the preconfigured measurement intervals may also be used for radio resource management (Radio Resource Management, RRM) by the terminal, etc., which is not limited by the present disclosure. In the above embodiment, the base station may send the indication information, where the indication information is used to indicate whether the base station supports the first request message sent by the receiving terminal, where the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval, that is, the base station informs the opposite terminal device whether the base station supports the preconfigured measurement interval that is requested to activate or deactivate by the terminal, so that the preconfigured measurement interval is ensured to be activated or deactivated, accuracy and reliability of positioning of the terminal are improved, and positioning delay is reduced.

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 3, and fig. 3 is a flowchart of an information transmission method according to an embodiment, which may be performed by a base station, and the method may include the following steps:

Step 301: in the step 301, a base station sends indication information to a 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 the embodiment of the disclosure, the base station may send the indication information to the terminal, so as to inform the terminal whether the base station supports the first request message sent by the receiving terminal, where the first request message is used to request the base station to activate or deactivate the preset measurement interval, that is, the base station may inform the terminal whether the base station supports the terminal to request the base station to activate or deactivate the preset measurement interval through the indication information. The terminal may determine whether to request activation or deactivation of the preconfigured measurement interval by the terminal itself based on the indication information.

In one possible implementation, the base station sends the indication information to the terminal in response to configuring the pre-configured measurement interval for the terminal. Alternatively, the base station may send the indication information to the terminal when configuring the preconfigured measurement interval for the terminal, where 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 of configuring the preconfigured measurement interval, which is not limited in the present disclosure.

Of course, the preconfigured measurement intervals may also be used for RRM or the like by the terminal, which is not limited by the present disclosure.

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

In the disclosed embodiment, 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 the terminal itself requests activation or deactivation of the preconfigured measurement interval, step 302 may be performed, at which time the base station may 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 may determine whether to activate or deactivate the preconfigured measurement interval according to the indication information, further, step 302 may be performed, where the base station receives the first request message sent by the terminal.

Of course, step 302 may not be performed at this time, i.e. the base station may receive a third request message sent by the core network device, e.g. the LMF, where 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 may send an activation message or a deactivation message to the terminal, thereby activating or deactivating the preconfigured measurement interval.

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

In another example, the indication information indicates that the base station allows the terminal to transmit the first request message, the terminal may determine whether to activate or deactivate the preconfigured measurement interval by itself according to the indication information, further, step 302 may be performed, and the base station receives the first request message transmitted by the terminal.

Of course, step 302 may not be performed at this time, i.e., the base station may receive a third request message sent by the LMF, where 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 the core network device, e.g., LMF, to the base station.

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

Or step 302 may still be performed, i.e. 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, where 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. Wherein, the base station can send the activation message or the deactivation message to the terminal through the DL MAC CE. The method ensures that the preconfigured measurement interval can be activated or deactivated, improves the accuracy and reliability of terminal positioning, and reduces positioning time delay.

In another example, the indication information indicates that the base station does not allow the terminal to transmit the first request message, step 302 cannot be performed. That is, the base station does not receive the first request message sent by the terminal, so that the signaling resource waste caused by that the terminal still sends the first request message to the base station is avoided.

In another example, the indication information indicates that the base station supports the terminal to transmit the first request message, and the base station allows the terminal to transmit the first request message, the terminal may determine whether to activate or deactivate the preconfigured measurement interval by itself according to the indication information, further, step 302 may be performed, and the base station receives the first request message transmitted by the terminal.

Of course, step 302 may not be performed at this time, i.e., the base station may receive a third request message sent by the LMF, where 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, step 302 cannot be performed. That is, the base station does not receive the first request message sent by the terminal, so that the signaling resource waste caused by that the terminal still sends the first request message to the base station is avoided.

In addition, the base station may receive a third request message sent by the LMF, where 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. Wherein, the base station can send the activation message or the deactivation message to the terminal through the DL MAC CE. The method ensures that the preconfigured measurement interval can be activated or deactivated, improves the accuracy and reliability of terminal positioning, and reduces positioning time delay. In one possible implementation, the base station may receive a first request message sent by the terminal via a first message. The first message may be an UpLink MEDIA ACCESS Control Element (UL MAC CE).

In the above embodiment, the base station may inform the terminal whether the base station supports the preset measurement interval requested to be activated or deactivated by the terminal, so as to ensure that the preset measurement interval can be activated or deactivated, improve the accuracy and reliability of positioning the terminal, and reduce the positioning delay.

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 4, fig. 4 is a flowchart of an information transmission method shown in an embodiment, which may be performed by a base station, and the method may include the following steps:

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

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

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

In one example, the first NRPPa message may be any one of the following: measuring a pre-configuration confirm (MEASUREMENT PRECONFIGURATION CONFIRM) message; transmitting a point information response (TRP INFORMATION RESPONSE) message; other NRPPa messages.

Other NRPPa messages here are other NRPPa messages than the measurement pre-configuration confirm message, the transmission point information response message.

Step 402: in the 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 second request information to a core network device, such as an LMF, and in response to receiving the second request information, the LMF may send a third request message to the base station.

In the disclosed embodiment, step 402 is optionally performed.

In one possible implementation, if the indication information indicates that the base station does not support and/or does not allow the request to activate or deactivate the pre-configured measurement interval by the terminal, step 402 may be performed, where the base station sends a second request message to the LMF requesting the LMF to send a third request message to the base station requesting the base station to activate or deactivate the pre-configured 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 pre-configured measurement interval, step 402 may not be performed, i.e. the terminal may send a first request message to the base station, the first request message being used to request that the base station activate or deactivate the pre-configured 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 pre-configured measurement interval, step 402 may be performed, i.e. the base station may send a second request message to the LMF at this time requesting the LMF to send a third request message to the base station, the third request message being used to request the base station to activate or deactivate the pre-configured measurement interval. Accordingly, the terminal may no longer send the first request message to the base station.

In another possible implementation, step 402 may be performed regardless of the content of the indication information, i.e. the default base station does not support or allow the terminal to request activation or deactivation of the pre-configured measurement interval, at which 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, the third request message being used to request the base station to activate or deactivate the pre-configured 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, and accordingly, step 403 may be performed directly, i.e. a third request message is sent directly by the LMF to the base station according to the second request information, where 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, and in the case that the LMF receives the second request message, it may be determined that the base station does not support or allow the terminal to transmit the first request message, so that the LMF may transmit a third request message to the base station according to the second request message.

It should be noted that the third request message functions similarly to the first request message, and is used to request the base station to activate or deactivate the preset measurement interval, and is different in that the third request message is sent to the base station by the LMF, the first request message is sent to the base station by the terminal, and in addition, the message format and content of the third request message are different from those of the first request message.

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

That is, the base station may transmit the indication information to the LMF together with the second request message through the first NRPPa message.

For example, the indication information is 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 capability of supporting the activation or deactivation of the preconfigured measurement interval requested by the terminal, in order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, the base station may perform step 402, send a second request message to the LMF, request 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.

Or the base station may not execute step 402, and the LMF sends the third request message to the base station according to the content of the indication information, so that the base station may directly receive the third request message.

For example, the indication information is used to instruct the base station not to allow the terminal to send the first request message, in order to activate or deactivate the preset measurement interval in time, and reduce the positioning delay, the base station may perform step 402, send a second request message to the LMF, request the LMF to send a third request message, where the third request message is used to request the base station to activate or deactivate the preset measurement interval.

For example, in the case that 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 perform step 402, where the base station sends a second request message to the LMF, requesting the LMF to send a third request message, where the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Or 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, where the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval. I.e. activation or deactivation of the preconfigured measurement intervals may be requested by the terminal.

Or when the indication information is used for indicating that the base station supports and/or allows the terminal to send the first request message, the LMF may send the third request message to the base station according to the content of the indication information, and the base station may directly receive the third request message without executing step 402.

For example, in the case that the indication information is used to instruct the base station to support 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 also perform step 402, send a second request message to the LMF, request the LMF to send a third request message, where the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Or the indication information is used for indicating the base station to support the terminal to send the first request message, and the base station does not allow the terminal to send the first request message temporarily, the base station does not need to execute step 402, and the terminal sends the first request message to the base station, wherein the first request message is used for requesting the base station to activate or deactivate the preset measurement interval. I.e. activation or deactivation of the preconfigured measurement intervals may be requested by the terminal.

Or the indication information is used for indicating the base station to support the terminal to send the first request message, and if the base station temporarily does not allow the terminal to send the first request message, the step 402 may not be executed, 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 the third request message.

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

In the disclosed embodiment, step 403 is optionally performed.

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

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

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

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

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

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

Accordingly, the base station may receive the first request message sent by the terminal without the LMF sending the third request message to the base station.

In another possible implementation, step 403 may be performed if the indication information indicates that the base station supports the request to activate or deactivate the preconfigured measurement interval by the terminal, and the base station temporarily does not allow the terminal to send the first request message.

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 in the above manner, thereby activating or deactivating the preconfigured measurement interval.

In the above embodiment, the base station may inform the LMF whether the base station supports the activation or deactivation of the preconfigured measurement interval requested by the terminal, so as to ensure that the preconfigured measurement interval can be activated or deactivated, improve the accuracy and reliability of terminal positioning, and reduce the positioning delay.

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 5, and fig. 5 is a flowchart of an information transmission method according to an embodiment, which may be performed by a base station, and the method may include the following steps:

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

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

In one 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: measuring a pre-configuration request (MEASUREMENT PRECONFIGURATION REQUIRED) message; -transmitting a point information request (TRP INFORMATION REQUEST) message; other NRPPa messages.

The other NRPPa messages here are other NRPPa messages than 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 the embodiment of the disclosure, the base station may send the indication information to the LMF based on a request of the LMF, and inform whether the LMF base station supports a first request message sent by the receiving 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 to activate or deactivate the preconfigured measurement interval requested by the LMF based on the indication information.

In one example, the LMF sends a fourth request message to the base station via a second NRPPa message, a second NRPPa message, which is a measurement pre-configuration request message, and accordingly, the base station may send the indication information to the LMF via a first NRPPa message, a first NRPPa message, which is a measurement pre-configuration acknowledgement message.

In another example, the LMF sends a fourth request message to the base station via a second NRPPa message, the second NRPPa message is a transmission point information request message, and accordingly, the base station may send the indication information to the LMF via a first NRPPa message, the first NRPPa message is a transmission point information response message.

In another example, the LMF transmits a fourth request message to the base station through a second NRPPa message, the second NRPPa message being another second NRPPa message except for the measurement pre-configuration request message and the transmission point information request message, and accordingly, the base station may transmit the indication information to the LMF through a first NRPPa message, the first NRPPa message being another NRPPa message except for the measurement pre-configuration confirm message and the transmission point information response message and for responding to the second NRPPa message.

The above is merely exemplary, and 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 according to the fourth request message, which falls within the protection scope of the present disclosure.

Step 503: in the 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 disclosed embodiment, step 503 is optionally performed. The implementation of step 503 is similar to step 402 and will not be described in detail here.

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

In the disclosed embodiment, step 504 is optionally performed. 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 may receive the fourth request message sent by the LMF, and send the indication information to the LMF based on the fourth request message, so as to ensure that the preconfigured measurement interval can be activated or deactivated, improve the accuracy and reliability of positioning the terminal, and reduce the positioning delay.

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 6, and fig. 6 is a flowchart of an information transmission method according to an embodiment, which may be performed by a base station, and the method may include the following steps:

step 601: in the step 601, the base station transmits indication information to the terminal.

The indication information is used for indicating whether the base station supports a first request message sent by a receiving terminal, and the first request message is used for requesting the base station to activate or deactivate a preset 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 the step 602, the base station receives the first request message sent by the terminal.

In the disclosed embodiment, step 602 is an optional step. The specific implementation is similar to the above step 302, and will not be repeated here.

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

In the embodiment of the present disclosure, the base station may send the indication information to the LMF based on a fourth request message sent by the core network device, for example, the LMF, and the specific implementation is similar to the above steps 501 to 502, which is not repeated herein.

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

Step 604: in the 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 disclosed embodiment, step 604 is optionally performed. 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 step 603 is optionally performed, and the base station directly performs the step 604, that is, the base station replaces the indication information with the second request message, and the specific implementation is already described in the embodiment, which is not repeated herein.

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

In the disclosed embodiment, step 605 is optionally performed. The implementation of step 605 is similar to step 403 and will not be described in detail herein.

It should be further noted that, step 602 and step 605 may be alternatively performed, that is, the base station may 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, so as to activate or deactivate the preconfigured measurement interval. Or the base station may receive a third request message transmitted by the LMF and transmit 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 the deactivation message to the terminal through the DL MAC CE.

In the above embodiment, the base station may send the indication information to the terminal and the LMF to inform the terminal and the LMF whether the base station supports receiving the first request message sent by the terminal, where the first request message is used to request the base station to activate or deactivate the preconfigured measurement interval, so as to ensure that the preconfigured measurement interval can be activated or deactivated, improve accuracy and reliability of positioning the terminal, and reduce positioning delay.

The information transmission method provided by the present disclosure is further described below from the terminal side.

An embodiment of the present disclosure provides an information transmission method, referring to fig. 7, fig. 7 is a flowchart of an information transmission method, which may be performed by a terminal, and the method may include the steps of:

Step 701: in the step 701, the terminal 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 the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

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

In one possible implementation, the terminal receives the indication information sent by the base station to the terminal in response to configuring the pre-configured measurement interval for the terminal.

In the above embodiment, the terminal may receive the indication information sent by the base station, so as to determine whether the base station supports activation or deactivation of the preconfigured measurement interval requested by the terminal, ensure that the preconfigured measurement interval can be activated or deactivated, improve accuracy and reliability of positioning the terminal, and reduce positioning delay.

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 8, fig. 8 is a flowchart of an information transmission method shown in an embodiment, which may be executed by a terminal, and the method may include the following steps:

Step 801: in the step 801, a terminal 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 the terminal, where the first request message is used to request the base station to activate or deactivate a preconfigured measurement interval.

The specific implementation is similar to the above step 701, and will not be described here again.

Step 802: in the 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 disclosed embodiment, step 802 is an optional step.

In one example, the indication information indicates that the base station supports the terminal to transmit the first request message, the terminal may determine whether to activate or deactivate the preconfigured measurement interval by itself according to the indication information, and further, the terminal may perform step 802 to transmit the first request message to the base station.

Of course, step 802 may not be performed at this time, i.e., the base station may receive a third request message sent by the LMF, where 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 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.

In another example, the indication information indicates that the base station allows the terminal to transmit the first request message, and the terminal may determine whether to activate or deactivate the preconfigured measurement interval by itself according to the indication information, further, step 302 may be performed, and the first request message is transmitted to the base station.

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

In another example, the indicating information indicates that the base station does not support the terminal to transmit 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 the signaling resource waste caused by the fact that the terminal still sends the first request message to the base station is avoided under the condition that the base station does not support the terminal to send the first request message.

Or the terminal may still perform step 802, sending 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, where 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. Wherein, the base station can send the activation message or the deactivation message to the terminal through the DL MAC CE. The method ensures that the preconfigured measurement interval can be activated or deactivated, improves the accuracy and reliability of terminal positioning, and reduces positioning time delay.

In another example, the indication information indicates that the base station does not allow the terminal to transmit the first request message, step 802 cannot be performed. Namely, the terminal does not send the first request message to the base station, so that the waste of signaling resources of the terminal is avoided.

In another example, the indication information indicates that the base station supports the terminal to transmit the first request message, and the base station allows the terminal to transmit the first request message, the terminal may determine whether to activate or deactivate the preconfigured measurement interval by itself according to the indication information, and further, step 802 may be performed, and transmit 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. Wherein, the base station can send the activation message or the deactivation message to the terminal through 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, step 802 cannot be performed. That is, the terminal does not send the first request message to the base station, so that the signaling resource waste caused by the fact that the terminal still sends the first request message to the base station is avoided.

In addition, the base station may receive a third request message sent by the LMF, where 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. Wherein, the base station can send the activation message or the deactivation message to the terminal through the DL MAC CE. The method ensures that the preconfigured measurement interval can be activated or deactivated, improves the accuracy and reliability of terminal positioning, and reduces positioning time delay. In one possible implementation, the terminal may send a first request message to the base station through a first message. Wherein the first message may be an 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.

The information transmission method provided by the present disclosure is described further below from the LMF side.

An embodiment of the present disclosure provides an information transmission method, referring to fig. 9, and fig. 9 is a flowchart of an information transmission method, which may be performed by a core network device, such as an LMF, according to an embodiment, and the method may include the following steps:

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

In the embodiment of the disclosure, a pre-configured measurement interval may be configured for a terminal by a base station. The process of configuring the preconfigured measurement interval for the terminal by the base station is similar to the steps 0 to 4 shown in fig. 1 and will not be described herein. Optionally, the preconfigured measurement interval is at least used for the terminal to make positioning related measurements.

Step 901 may be performed prior to activating or deactivating the preconfigured measurement interval, the indication information sent by the receiving base station being received by the core network device, e.g. LMF.

In the embodiment of the disclosure, the indication information is used for informing the LMF whether the base station supports the first request message sent by the receiving terminal, and the first request message is used for requesting the base station to activate or deactivate the preconfigured measurement interval. The LMF may determine whether to request activation or deactivation of the preconfigured measurement interval by the LMF based on the indication information.

In one example, the first NRPPa message may be any one of the following: measuring a pre-configuration confirm message; transmitting a point information response message; other NRPPa messages.

In one example, indication information may be used to instruct the base station to support the terminal to send the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal. At this time, the LMF may not transmit a third request message to the base station according to the indication information, the third request message requesting the base station to activate or deactivate the preconfigured measurement interval. Of course, the LMF may also send the third request message to the base station according to the indication information, which is not limited in this disclosure.

In another example, the indication information may be used to instruct a base station to allow the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement interval requested by the terminal and the base station currently allows the terminal to send this first request message to the base station. At this time, the LMF may not transmit a third request message to the base station according to the indication information, the third request message requesting the base station to activate or deactivate the preconfigured measurement interval. Of course, the LMF may also send the third request message to the base station according to the indication information, which is not limited in this disclosure.

In another example, indication information may be used to indicate that the base station does not support the terminal to send the first request message. I.e. the base station does not have the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal. At this time, the LMF may send the third request message to the base station according to the indication information, where 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 transmit the first request message. The terminal may determine that the base station temporarily or permanently does not allow the terminal to transmit the first request message according to the indication information. At this time, the LMF may send the third request message to the base station according to the indication information, where 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 instruct a base station to support the terminal to transmit the first request message, and the base station allows the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal, while the base station allows the terminal to send the first request message based on load, traffic demand etc. At this time, the LMF may send or not send the third request message to the base station according to the indication information, where the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

Or the indication information may be used to indicate that the base station supports the terminal to transmit the first request message, and that the base station does not allow the terminal to transmit the first request message. I.e. the base station has the capability to support the activation or deactivation of the preconfigured measurement intervals requested by the terminal, while the base station temporarily does not allow the terminal to send the first request message based on load, traffic demand etc. At this time, the LMF may send the third request message to the base station according to the indication information, where the third request message is used to request the base station to activate or deactivate the preconfigured measurement interval.

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

In some alternative embodiments, an information transmission method is provided in the embodiments of the present disclosure, referring to fig. 10, and fig. 10 is a flowchart of an information transmission method according to an embodiment, which may be performed by a core network device, such as an 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 a first request message sent by a receiving 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 described above, and will not be described in detail here.

Step 1002: in the 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 disclosed embodiment, step 1002 is optionally performed.

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 may be performed, receiving a second request message sent by the base station, the second request message being used to request the LMF to send a third request message to the base station, the third request message being 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 pre-configured measurement interval, step 1002 may not be performed, i.e. the terminal may send a first request message to the base station, the first request message being used to request the base station to activate or deactivate the pre-configured 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, i.e. the LMF may receive a second request message sent by the base station, the second request message being for requesting the LMF to send a third request message to the base station, the third request message being for requesting 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 1002 may be performed regardless of the content of the indication information, i.e. the default base station does not support or allow the terminal to request activation or deactivation of the preconfigured measurement interval, at which time the LMF may receive a second request message sent by the base station, the second request message being used to request the LMF to send a third request message to the base station, the third request message being 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 manner, step 1001 may not be performed, step 1002 may be directly performed, and accordingly, subsequent step 1003 may be continuously performed, that is, the LMF does 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 it is determined that the base station does not support or allow the terminal to send the first request message, and at this time, the LMF may directly send the third request message to the base station according to the second request message.

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

That is, the LMF may receive the indication information and the second request message transmitted from the base station through the first NRPPa message.

For example, the indication information is used to instruct the base station not to support the terminal to send the first request message, that is, the base station does not have the capability of supporting the activation or deactivation of the preconfigured measurement interval by the terminal, in order to timely activate or deactivate the preconfigured measurement interval and reduce the positioning delay, step 1002 may be executed, where a second request message sent by the base station is received, where the second request message is used to request the LMF to send the 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.
