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.

The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms "a", "an", "the" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. 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".

When the terminal can only maintain one set of logged MDT configuration information, if this set of logged MDT configuration information is more targeted than the new logged MDT configuration information sent by the network device, and the obtained logged MDT measurement results are more accurate, it is obviously necessary to protect the original logged MDT configuration information on the terminal from being overwritten.

In order to improve the coverage scheme of logged MDT configuration information, the present disclosure provides the following information transmission method, device, and storage medium. As shown in FIG1, it is a schematic diagram of a network architecture diagram applicable to the present disclosure scheme. The network in the present disclosure can be a 4G network, a 5G network, a 6G network, or a future communication network, etc., and the present disclosure does not limit this. The network architecture includes:

Terminal 101 (including 101-1, 101-2, 101-3, ... in FIG. 1), terminal 101 may be a smart phone, a desktop computer, a laptop computer, a tablet computer, etc., which is not limited in the present disclosure.

The network device 102 includes but is not limited to a base station, an access network device, etc., wherein the base station may be a 4G base station, a 5G base station, or a future 6G base station, and the access network device may be a 4G access network device, a 5G access network device, or a future 6G access network device, etc., which is not limited in the present disclosure. Optionally, the network device 102 may also include a core network device, etc.

In some embodiments, when the terminal 101 is configured with logged MDT configuration information, the terminal 101 can report first information to the network device 102, and the first information can be used by the network device 102 to determine whether to cover the logged MDT configuration information on the terminal 101.

In other embodiments, the network device 102 may determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal, business requirements, etc. In some examples, overwriting the logged MDT configuration information includes replacing the previous logged MDT configuration information with the new logged MDT configuration information; or overwriting the logged MDT configuration information also includes deleting the previous logged MDT configuration information; or overwriting the logged MDT configuration information also includes setting the previous logged MDT configuration information to invalid, etc. In short, the present disclosure does not limit the specific implementation method of overwriting the logged MDT configuration information.

In one example, in an inter-RAT scenario, for example, when a terminal moves from a cell under one RAT to a cell under another RAT, the network device 102 can determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101.

In a specific implementation, the network device 102 can determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101 (including the RAT type information corresponding to the existing logged MDT configuration information of the terminal 101, i.e., the first RAT type information) and the RAT type of the network device 102 itself.

For example, the first information reported by the terminal 101 includes the first RAT type information corresponding to the logged MDT configuration information. When the RAT type corresponding to the network device 101 is different from the first RAT type, the network device 101 can determine to cover the logged MDT configuration information on the terminal 101. In this way, the accuracy of the terminal executing logged MDT under the current RAT type is improved.

In another specific implementation, the network device 102 can determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101 (including the RAT type information corresponding to the existing logged MDT configuration information of the terminal 101, i.e., the first RAT type information), the RAT type of the network device 102 itself, and the logged MDT measurement requirements.

For example, the first information reported by the terminal 101 includes the first RAT type information corresponding to the logged MDT configuration information. When the RAT type corresponding to the network device 101 is different from the first RAT type, the network device 101 can determine not to cover the logged MDT configuration information on the terminal 101 in combination with the logged MDT measurement requirements.

In another specific implementation, the network device 102 can determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101 (including the RAT type information corresponding to the existing logged MDT configuration information of the terminal 101, i.e., the first RAT type information), the type of the existing logged MDT configuration information of the terminal (for example, signaling-based logged MDT configuration information, or management-based logged MDT configuration information), and the RAT type of the network device 102 itself.

For example, the logged MDT configuration information on the terminal is the signaling-based logged MDT configuration information under the LTE system. The network device 102 can determine that the signaling-based logged MDT configuration information under the LTE system will not be overwritten by the management-based logged MDT configuration information under the LTE system or the signaling-based logged MDT configuration information under the NR system or the management-based logged MDT configuration information under the NR system, that is, the network device 102 determines that the logged MDT configuration information on 101 will not be overwritten.

For example, the logged MDT configuration information on the terminal is the signaling-based logged MDT configuration information under the NR system. The network device 102 can determine that the signaling-based logged MDT configuration information under the NR system will not be overwritten by the management-based logged MDT configuration information under the NR system or the signaling-based logged MDT configuration information under the LTE system or the management-based logged MDT configuration information under the LTE system, that is, the network device 102 determines that the logged MDT configuration information on 101 will not be overwritten.

In another example, in an intra-LTE scenario, for example, when a terminal moves from one cell in the LTE system to another cell in the LTE system, the network device 102 may also determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101.

For example, the first information reported by the terminal 101 includes the first RAT type information corresponding to the logged MDT configuration information. When the RAT type corresponding to the network device 101 is the same as the first RAT type and both include the LTE system, it can be determined not to cover the logged MDT configuration information on the terminal 101. In this way, waste of network device resources is avoided.

For another example, the first information reported by the terminal 101 includes the first RAT type information corresponding to the logged MDT configuration information. The network device 101 can determine the logged MDT configuration information on the covered terminal 101 in combination with the type of the logged MDT configuration information on the terminal when the RAT type corresponding to itself is the same as the first RAT type and both include an LTE system.

For example, the logged MDT configuration information on the terminal is the signaling-based logged MDT configuration information under the LTE system. The network device 102 can determine that the management-based logged MDT configuration information under the LTE system will not overwrite the signaling-based logged MDT configuration information under the LTE system, that is, the network device 102 determines that it will not overwrite the logged MDT configuration information on 101.

For example, the logged MDT configuration information on the terminal is the management-based logged MDT configuration information under the LTE system. The network device 102 can determine that the signaling-based logged MDT configuration information under the LTE system will not overwrite the management-based logged MDT configuration information under the LTE system, that is, the network device 102 determines that it will not overwrite the logged MDT configuration information on 101.

Wherein, management-based MDT means that the Operation Administration and Maintenance (OAM) device notifies the access network device to perform MDT, and the access network device selects a terminal from the terminals covered by the access network device to perform MDT measurement based on a predetermined strategy. Accordingly, management-based logged MDT configuration information refers to the logged MDT configuration information configured by the network device 102 for the selected terminal. Generally, the management-based logged MDT configuration information is sent by the network device 102 to multiple terminals 101.

Signaling-based MDT is that the OAM device notifies the access network device to select certain specific terminals for MDT measurement. Accordingly, the signaling-based logged MDT configuration information refers to the logged MDT configuration information configured by the network device 102 for the specific terminal. Generally, the signaling-based logged MDT configuration information is sent by the network device 102 to a separate terminal 101.

In another example, in an intra-NR scenario, for example, when a terminal moves from one cell in the NR system to another cell in the NR system, the network device 102 may also determine whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information reported by the terminal 101.

The way in which the network device 102 determines whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information is similar to the way in which the network device 102 determines whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information in the intra-LTE scenario, and will not be repeated here.

The present disclosure can improve the coverage protection mechanism of logged MDT configuration information and improve the reliability of terminal execution of logged MDT.

In order to better illustrate the technical solution provided by the present disclosure, several scenarios to which the present disclosure is applicable are first introduced as examples.

The first scenario is an inter-RAT scenario, for example, a terminal moves from a cell under one wireless communication system to a cell under another wireless communication system. For example, the terminal moves from cell #1 under the Long Term Evolution (LTE) system to cell #2 under the New Radio (NR) system, or the terminal moves from cell #3 under the NR system to cell #4 under the LTE system.

The second scenario is an intra-LTE scenario. For example, a terminal moves from one cell in the LTE system to another cell in the LTE system.

The third scenario is the New Radio (NR) system internal (inra-NR) scenario. For example, the terminal moves from one cell under the NR system to another cell under the NR system.

The following information transmission method provided by the present disclosure may be applicable to but not limited to at least one of the above scenarios.

The following first introduces 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. 2 , 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:

In step 201, when the logged MDT configuration information is configured, the first information is reported to the network device.

In the embodiments of the present disclosure, logged MDT configuration information refers to information used by a terminal to perform logged MDT measurements, and may include but is not limited to at least one of the following information: conditions for performing measurements (for example, performing measurements when the terminal is in an idle state or an inactive state); measurement content (for example, the category of the public land mobile network PLMN that needs to be measured); timing for reporting measurement results (for example, reporting logged MDT measurement results each time the terminal enters a connected state), etc.

In an embodiment of the present disclosure, the first information can be used by a network device to determine whether to cover the logged MDT configuration information on a terminal, and further, can be used to assist the network device in determining whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal.

In one possible implementation, the first information may be reported by the terminal to the network device via a radio resource control (RRC) message.

Exemplarily, the RRC message includes, but is not limited to, an RRC recovery complete (RRCResumeComplete) message, an RRC reestablishment complete (RRCReestablishment) message, an RRC connection establishment complete (RRCSetupComplete) message, an RRC reconfiguration complete (RRCReconfigurationComplete) message, and the like.

In one possible implementation, the first information may include but is not limited to RAT type information. Further, the first information indicates that the terminal device already has logged MDT configuration information corresponding to the RAT type, for example, the terminal device already has logged MDT configuration information corresponding to the first RAT type.

In one example, the RAT type corresponding to the logged MDT configuration information includes the RAT type corresponding to the network device that sends the logged MDT configuration information. For example, the terminal device receives the logged MDT configuration information sent by a network device of the first RAT type, and the logged MDT configuration information corresponds to the first RAT type.

In another example, the RAT type corresponding to the logged MDT configuration information refers to the RAT type corresponding to the network device to which the terminal reports the logged MDT measurement results. For example, the terminal device can also receive logged MDT configuration information sent by a network device that is not of the first RAT type, and indicate that the logged MDT configuration information corresponds to the first RAT type. For example, the terminal device reports a measurement report to the network device of the first RAT type.

In a possible implementation, the first RAT type includes but is not limited to any one of the following: an LTE system; a NR system. Accordingly, the first information includes an LTE system or a NR system.

Exemplarily, when the terminal is configured with logged MDT configuration information corresponding to the LTE system, first information may be reported to the network device, and the first information may include the LTE system. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system. At this time, the network device may be a network device corresponding to any RAT type.

For example, when a terminal moves from a cell in an NR system to a cell in an LTE system, it can report first information to a network device in the LTE system. The first information may include RAT type information. Furthermore, the first information indicates the first RAT information. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system.

For another example, when a terminal moves from a cell in an LTE system to a cell in an NR system, it can report first information to a network device in the NR system, and the first information may include the LTE system. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system.

For example, when a terminal moves from a cell in an NR system to a cell in an LTE system, it can report first information to a network device in the LTE system, and the first information may include the NR system. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the NR system.

For another example, when a terminal moves from a cell in an LTE system to a cell in an NR system, it can report first information to a network device in the NR system, and the first information may include the NR system. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the NR system.

For another example, when a terminal moves from a cell in an LTE system to another cell in the LTE system, it can report first information to a network device in the LTE system, and the first information may include the LTE system. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system.

For another example, when a terminal moves from a cell in an NR system to another cell in the NR system, it can report first information to a network device in the NR system, and the first information may include the NR system. After receiving the first information, the network device can determine that the terminal is configured with logged MDT configuration information corresponding to the NR system.

In one possible implementation, the logged MDT configuration information is configured, which may include but is not limited to at least one of the following: receiving the logged MDT configuration information sent by the network device; recording the logged MDT measurement results; the first timer is in a running state; wherein the first timer is used to determine whether the logged MDT configuration information is valid.

In one example, the terminal receives logged MDT configuration information sent by a network device of a first RAT system, and the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. The first RAT type includes but is not limited to any of the following: LTE system; NR system.

For example, in response to the terminal receiving logged MDT configuration information sent by the network device. The logged MDT configuration information corresponds to a first RAT type, and the first RAT type includes an LTE system or an NR system. The terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. Accordingly, the terminal can report the first information to the network device currently accessed by the terminal (the RAT type corresponding to the network device can be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal.

In another example, the terminal records logged MDT measurement results, which refer to the measurement results obtained by the terminal when performing logged MDT measurement based on logged MDT measurement configuration information, including but not limited to: geographic location information when the measurement occurs, network device identification accessed during measurement, and a measured PLMN list.

The terminal records the logged MDT measurement result, which means that the terminal performs the logged MDT measurement based on the configured logged MDT configuration information and records the corresponding logged MDT measurement result. At this time, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. The first RAT type includes but is not limited to any of the following: LTE system; NR system.

For example, in response to the terminal recording a logged MDT measurement result, which is a measurement result obtained by the terminal performing logged MDT measurement based on logged MDT configuration information, the terminal determines that the logged MDT configuration information is configured. Further, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured.

Accordingly, the terminal may report the first information to the network device currently connected to the terminal (the RAT type corresponding to the network device may be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal. The first RAT type includes but is not limited to any of the following: LTE system; NR system.

In another example, the first timer includes but is not limited to a T330 timer, wherein the T330 timer is in a running state, and the terminal can determine that the logged MDT configuration information is valid. When the T330 timer times out, that is, the T330 timer stops running, the logged MDT configuration information on the terminal will be deleted, but the logged MDT record will still be retained on the terminal. The logged MDT record refers to the log information of the terminal executing logged MDT, that is, the terminal has performed logged MDT measurements based on the configured logged MDT measurement configuration information.

In an embodiment of the present disclosure, when the first timer is in a running state, the terminal determines that the logged MDT configuration information is configured. Further, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. The first RAT type includes but is not limited to any of the following: LTE system; NR system.

For example, when a first timer on the terminal is in a running state, the first timer includes a T330 timer, and the terminal determines that logged MDT configuration information is configured. Further, the terminal determines that logged MDT configuration information is configured. Further, the terminal determines that logged MDT configuration information corresponding to the first RAT type is configured.

Exemplarily, the logged MDT configuration information may include a combination of the above-mentioned situations.

For example, in response to the terminal receiving the logged MDT configuration information sent by the network device and the first timer is running, the terminal determines that the logged MDT configuration information is configured, and further, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. Among them, the first RAT type includes an LTE system or an NR system, and the first timer includes but is not limited to a T330 timer. Accordingly, the terminal can report the first information to the network device currently accessed by the terminal (the RAT type corresponding to the network device may be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal. The first RAT type includes but is not limited to any of the following: LTE system; NR system.

For another example, in response to the terminal receiving the logged MDT configuration information sent by the network device, and the terminal recording the logged MDT measurement result, the terminal determines that the logged MDT configuration information is configured, and further, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. Accordingly, the terminal can report the first information to the network device currently connected to the terminal (the RAT type corresponding to the network device can be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal. The first RAT type includes, but is not limited to, any of the following: LTE system; NR system.

For another example, in response to the terminal recording a logged MDT measurement result and the first timer being in a running state, the terminal determines that logged MDT configuration information is configured, and further, the terminal determines that logged MDT configuration information corresponding to the first RAT type is configured. Accordingly, the terminal can report the first information to the network device currently accessed by the terminal (the RAT type corresponding to the network device can be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal, and further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal. The first RAT type includes but is not limited to any of the following: LTE system; NR system. For another example, in response to the terminal receiving the logged MDT configuration information sent by the network device, the terminal records the logged MDT measurement result, and the first timer is in a running state, the terminal determines that the logged MDT configuration information is configured, and further, the terminal determines that the logged MDT configuration information corresponding to the first RAT type is configured. Accordingly, the terminal may report the first information to the network device to which the terminal is currently connected (the RAT type corresponding to the network device may be the same as or different from the first RAT type), and the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, the first information is used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal. The first RAT type includes but is not limited to any of the following: LTE system; NR system. The above is only an exemplary description. In actual applications, combinations of one or more situations in which the logged MDT configuration information corresponding to the first RAT type is configured should fall within the scope of protection of this disclosure.

In a possible implementation, the terminal may report the first information to the network device in a manner including but not limited to the following manners:

In the first manner, after storing (or recording) the first information, the terminal reports the first information to the network device.

In this way, the terminal needs to perform a storage (or recording) action.

The terminal may store (or record) the first information in a designated variable.

In one example, the specified variables include, but are not limited to, configuration variables and/or reporting variables.

Furthermore, the configuration variables include but are not limited to the logging measurement configuration variable VarLogMeasConfig.

Furthermore, the report variables include but are not limited to the record measurement report variable VarLogMeasReport.

For example, after recording the first information into the configuration variable, the terminal reports the first information to the network device. The configuration variable includes but is not limited to VarLogMeasConfig.

For another example, after recording the first information into the report variable, the terminal reports the first information to the network device. The report variable includes but is not limited to VarLogMeasReport.

For another example, after recording the first information into the configuration variable and the report variable, the terminal reports the first information to the network device, wherein the configuration variable includes but is not limited to VarLogMeasConfig, and the report variable includes but is not limited to VarLogMeasReport.

Exemplarily, when the terminal is configured with logged MDT configuration information, the terminal records the first information into a specified variable and then reports the first information to the network device. The specified variable includes but is not limited to a configuration variable and/or a report variable, the configuration variable includes but is not limited to VarLogMeasConfig, and the report variable includes but is not limited to VarLogMeasReport. The first information includes RAT type information, and further, the first information includes first RAT type information corresponding to the logged MDT configuration information already on the terminal, and the first RAT type includes an LTE system or an NR system.

The second way is to report the first information directly to the network device.

In this manner, the terminal does not need to perform storage (or recording), and can directly report the first information to the network device.

Exemplarily, when the terminal is configured with logged MDT configuration information, the terminal directly reports the first information to the network device.

In another possible implementation manner, the terminal may determine the first RAT type, and then report first information to the network device, where the first information includes RAT type information, and specifically may include the first RAT type information.

In one example, the terminal may determine the first RAT type based on first indication information sent by the network device.

In an embodiment of the present disclosure, the terminal can receive logge MDT configuration information sent by a network device, and at the same time receive first indication information sent by the network device to the terminal for determining the first RAT type.

In another example, the terminal may determine the first RAT type according to its own wireless access mode, that is, the terminal autonomously determines the first RAT type.

In the embodiment of the present disclosure, after the terminal determines the first RAT type by using any of the above methods, it can report first information to the network device, where the first information includes the first RAT type information.

In a possible implementation, when the terminal is configured with logged MDT configuration information and the reporting timing arrives, the terminal reports the first information to the network device.

In one example, the reporting opportunity may include but is not limited to at least one of the following: entering a connected state; residing in a cell of a second RAT type, wherein the second RAT type is different from the first RAT type; receiving a request message sent by a network device, the request message being used to request the terminal to report the first information.

Exemplarily, each time the terminal enters the connected state, the first information may be reported to the network device. The first information includes RAT type information, and specifically may include first RAT type information. The first RAT type includes but is not limited to an LTE system and an NR system.

Exemplarily, the terminal resides in a cell of the second RAT type, which is different from the first RAT type. For example, the terminal previously resided in a cell in the LTE system and currently resides in a cell in the NR system. The terminal can report the first information to the network device.

Alternatively, the terminal previously resided in a cell in the NR system, and currently resides in a cell in the LTE system. The terminal can report the first information to the network device.

Exemplarily, the terminal reports the first information to the network device based on a request message from the network device.

Exemplarily, each time the terminal enters the connected state and receives a request message from the network device, the request message is used to request the terminal to report the first information, and the terminal reports the first information to the network device.

Exemplarily, each time the terminal enters the connected state and resides in a cell of the second RAT type, where the second RAT type is different from the first RAT type, the terminal reports the first information to the network device.

Exemplarily, the terminal resides in a cell of the second RAT type and receives a request message sent by a network device, the second RAT type is different from the first RAT type, the request message is used to request the terminal to report the first information, and the terminal reports the first information to the network device.

Exemplarily, each time the terminal enters a connected state, currently resides in a cell of the second RAT type and receives a request message sent by a network device, the second RAT type is different from the first RAT type, and the request message is used to request the terminal to report the first information. At this time, the terminal reports the first information to the network device.

In a possible implementation, the terminal may report the first information to the network device in the following manner:

In the first manner, the terminal informs the network device of the specific content of the first information.

Among them, the first information includes RAT type information, specifically including the first RAT type information corresponding to the logged MDT configuration information, for example, the first information includes an LTE system or an NR system.

Exemplarily, the protocol defines the format of the RAT type indication field, and the terminal directly reports the RAT type indication field so that the network device determines the first RAT type.

The format of the RAT Type Indication field is as follows:

sigLoggedMeasRatType-r18 ENUMERATED{nr,e-utra,spare1}OPTIONAL,--Need R

Exemplarily, the protocol defines the format of an LTE system indication field, where the LTE system indication field is used to indicate whether the first RAT type includes an LTE system. The format of the LTE system indication field is as follows:

sigLoggedMeasLTEType-r18 BOOLEAN

Exemplarily, the protocol defines the format of the NR system indication field, where the NR system indication field is used to indicate whether the first RAT type includes an NR system. The format of the NR system indication field is as follows:

sigLoggedMeasNRType-r18 BOOLEAN

In one possible implementation, the terminal sends the first information to the network device by reporting the above-mentioned indication fields, such as the RAT type indication field, the LTE system indication field, the NR system indication field and the corresponding field values, where the first information specifically includes the first RAT type information.

For example, the terminal reports a RAT type indication field, and the RAT type indication field is used to indicate first information, such as indicating LTE or NR.

For another example, the terminal reports the LTE system indication field. When the LTE system indication field is set to true, it is used to indicate that the first RAT type includes the LTE system. If the LTE system indication field is set to false, it is used to indicate that the first RAT type includes the NR system.

For another example, the terminal reports the NR system indication field. If the NR system indication field is set to true, it is used to indicate that the first RAT type includes the NR system. If the NR system indication field is set to false, it is used to indicate that the first RAT type includes the LTE system.

In another possible implementation, the terminal sends the first information to the network device by reporting the above-mentioned LTE system indication field or NR system indication field within a preset time period after accessing the network device, and the first information specifically includes the first RAT type information. The duration of the preset time period can be agreed upon by the protocol or configured by the network device, and this disclosure is not limited to this.

For example, the protocol stipulates the format of the above-mentioned LTE system indication field. If the terminal reports the LTE system indication field, the network device determines that the first RAT type includes the LTE system. If the terminal does not report the LTE system indication field, the network device can determine that the first RAT type includes the NR system.

For another example, the protocol stipulates the above-mentioned NR system indication field. If the terminal reports the NR system indication field, the network device determines that the first RAT type includes the NR system. If the terminal does not report the NR system indication field, the network device can determine that the first RAT type includes the LTE system.

In the second manner, the terminal sends the first information to the network device through an implicit indication manner.

Exemplarily, the terminal informs the network device whether the logged MDT configuration information belongs to inter-RAT configuration information.

In a possible implementation, the protocol specifies the format of the inter-RAT indication field. If the field is set to true, it indicates that the logged MDT configuration information belongs to the inter-RAT configuration information. If the field is set to false, it indicates that the logged MDT configuration information does not belong to the inter-RAT configuration information.

The format of the inter-RAT indication field is as follows:

sigLoggedMeasInterType-r18 BOOLEAN

In another possible implementation manner, the protocol stipulates the format of the inter-RAT indication field, and the terminal sends the first information to the network device by determining whether to report the inter-RAT indication field.

If the terminal reports the inter-RAT indication field to the network device within the preset period, the network device determines that the logged MDT configuration information belongs to the inter-RAT configuration information. If the terminal does not report the inter-RAT indication field to the network device within the preset period, the network device determines that the logged MDT configuration information does not belong to the inter-RAT configuration information. The duration of the preset period can be agreed upon by the protocol or configured by the network device, and this disclosure does not limit this.

For example, the terminal reports the inter-RAT indication field to the network device within a preset period, and the network device determines that the logged MDT configuration information belongs to the inter-RAT configuration information. The network device can determine whether to overwrite the logged MDT configuration information under the inter-RAT system on the terminal based on the fact that the logged MDT configuration information belongs to the inter-RAT configuration information.

For another example, if the terminal does not report the inter-RAT indication field to the network device within the preset period, and the network device belongs to the network device in the LTE system, the network device can determine that the logged MDT configuration information does not belong to the inter-RAT configuration information. Further, at this time, it is determined that the terminal is in the intra-LTE scenario, and the network device can determine whether to cover the logged MDT configuration information in the LTE system on the terminal based on the fact that the logged MDT configuration information does not belong to the inter-RAT configuration information.

The network devices involved in the above embodiments may include but are not limited to base stations, access network devices, etc., wherein the base stations may be 4G base stations, 5G base stations or future 6G base stations, and the access network devices may be 4G access network devices, 5G access network devices or future 6G access network devices, etc. Optionally, the network devices may also include core network devices, etc.

In one possible implementation, the logged MDT configuration information includes at least one of the following: management-based logged MDT configuration information; signaling-based logged MDT configuration information.

Among them, management-based MDT means that the OAM device notifies the access network device to perform MDT, and the access network device selects a terminal from the terminals covered by the access network device to perform MDT measurement based on a predetermined strategy. Correspondingly, management-based logged MDT configuration information refers to the logged MDT configuration information configured by the network device for the selected terminal. Generally, management-based logged MDT configuration information is sent by the network device to multiple terminals.

Signaling-based MDT is that the OAM device notifies the access network device to select certain specific terminals for MDT measurement. Correspondingly, signaling-based logged MDT configuration information refers to the logged MDT configuration information configured by the network device for the specific terminal. Generally, signaling-based logged MDT configuration information is sent by the network device to a separate terminal.

In one example, the terminal reports first information to the network device so that the network device determines whether to overwrite management-based logged MDT configuration information on the terminal with management-based logged MDT configuration information.

For example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines, based on the first information, whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal through the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal through the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal through the management-based logged MDT configuration information under the NR system.

In another example, the terminal reports first information to the network device so that the network device determines whether to overwrite the signaling-based logged MDT configuration information on the terminal with the management-based logged MDT configuration information.

For example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal through the management-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal with the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal with the management-based logged MDT configuration information under the NR system.

In another example, the terminal reports first information to the network device so that the network device determines whether to overwrite the management-based logged MDT configuration information on the terminal with the signaling-based logged MDT configuration information.

For example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal through the signaling-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal through the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal with the signaling-based logged MDT configuration information under the NR system.

In another example, the terminal reports first information to the network device so that the network device determines whether to overwrite the signaling-based logged MDT configuration information on the terminal with the signaling-based logged MDT configuration information.

For example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal through the signaling-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal through the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the terminal reports first information to the network device, and the network device determines whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal through the signaling-based logged MDT configuration information under the NR system.

In the above embodiment, the terminal reports the first information to the network device, and the network device can determine whether to overwrite the logged MDT configuration information on the terminal based on the first information, thereby improving the coverage protection mechanism of the logged MDT configuration information on the terminal and improving the reliability of the terminal executing logged MDT.

In some optional embodiments, referring to FIG. 3 , FIG. 3 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:

In step 301, first information is cleared.

Among them, the first information is used by the network device to determine whether to cover the logged MDT configuration information on the terminal. Further, it can be used by the network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal.

Exemplarily, the RRC message includes but is not limited to an RRC recovery complete message, an RRC reconstruction complete message, an RRC connection establishment complete message, etc.

The RAT type corresponding to the logged MDT configuration information refers to the RAT type corresponding to the network device that sends the logged MDT configuration information. For example, the terminal device receives the logged MDT configuration information sent by the network device of the first RAT type, and the logged MDT configuration information corresponds to the first RAT type.

Alternatively, the RAT type corresponding to the logged MDT configuration information refers to the RAT type corresponding to the network device to which the terminal reports the logged MDT measurement results. For example, the terminal device can also receive logged MDT configuration information sent by a network device that is not of the first RAT type, and indicate that the logged MDT configuration information corresponds to the first RAT type. For example, the terminal device reports a measurement report to the network device of the first RAT type.

In a possible implementation manner, when the terminal stores (or records) the first information, the terminal clears the first information.

In one example, the terminal storing (or recording) the first information may include: the terminal storing (or recording) the first information into a designated variable.

The specified variables include but are not limited to configuration variables and/or report variables.

In one example, clearing the first information includes at least one of the following: clearing the first information when the logged MDT configuration information expires; clearing the first information when the logged MDT record is reported to the network device; clearing the first information after a preset period of time; clearing the first information when the logged MDT configuration information under a new RAT sent by the network device is received.

Exemplarily, when the logged MDT configuration information exceeds the validity period, i.e., expires, the terminal clears the first information. The validity period of the logged MDT configuration information may be agreed upon by a protocol or sent to the terminal by a network device, which is not limited in the present disclosure.

For example, the terminal receives the logged MDT configuration information sent by the network device, and at the same time receives the validity period of the logged MDT configuration information sent by the network device. When the logged MDT configuration information exceeds the validity period, that is, expires, the terminal clears the first information.

Exemplarily, when the terminal has reported the logged MDT record to the network device, specifically, when the terminal has reported all the logged MDT records to the network device, the terminal may clear the first information. The logged MDT record is log information of the terminal executing logged MDT, that is, the terminal has executed logged MDT measurement based on the configured logged MDT measurement configuration information.

Exemplarily, after a preset time period, the terminal may clear the first information, wherein the preset time period may be agreed upon by a protocol or sent to the terminal by a network device, which is not limited in the present disclosure.

Exemplarily, when the terminal receives the logged MDT configuration information under the new RAT sent by the network device, the first information is cleared. For example, the terminal is previously configured with the logged MDT configuration information of the LTE system, and after the terminal receives the logged MDT configuration information in the NR system sent by the network device, the first information can be cleared.

Exemplarily, when a combination of the above-mentioned multiple contents is met, the terminal clears the first information.

For example, after a preset period of time, and all logged MDT records are reported to the network device, the first information is cleared.

For another example, when all logged MDT records are reported to the network device, and the terminal receives the logged MDT configuration information under the new RAT sent by the network device, the first information is cleared.

The above is only an exemplary description, and all solutions for clearing the first information should fall within the protection scope of this disclosure.

In the above embodiment, the terminal can automatically clear the first information, which improves the reliability of the terminal performing logged MDT measurements while avoiding excessive occupation of terminal resources and having high availability.

In some optional embodiments, the terminal may receive second indication information sent by the network device, where the second indication information is used to indicate that the logged MDT configuration information is management-based logged MDT configuration information under the LTE system, or to indicate that the logged MDT configuration information is signaling-based logged MDT configuration information under the LTE system.

In one possible implementation, the terminal may receive logged MDT configuration information sent by a network device, and simultaneously receive second indication information sent by the network device, where the second indication information is used to indicate that the logged MDT configuration information belongs to management-based logged MDT configuration information under the LTE system.

Exemplarily, the terminal can receive logged MDT configuration information sent by a network device in the LTE system, and can also receive second indication information sent by the network device, and determine based on the second indication information that the logged MDT configuration information is management-based logged MDT configuration information under the LTE system.

In one possible implementation, the terminal may receive logged MDT configuration information sent by a network device, and simultaneously receive second indication information sent by the network device, where the second indication information is used to indicate that the logged MDT configuration information belongs to signaling-based logged MDT configuration information under the LTE system.

Exemplarily, the terminal can receive logged MDT configuration information sent by a network device in the LTE system, and can also receive second indication information sent by the network device, and determine based on the second indication information that the logged MDT configuration information is signaling-based logged MDT configuration information under the LTE system.

In the NR system, the terminal can also use a similar method to determine whether the logged MDT configuration information belongs to the management-based logged MDT configuration information or the signaling-based logged MDT configuration information in the NR system.

Exemplarily, the terminal can receive logged MDT configuration information sent by a network device in the NR system, and can also receive second indication information sent by the network device, and determine based on the second indication information that the logged MDT configuration information is management-based logged MDT configuration information under the NR system.

Exemplarily, the terminal can receive logged MDT configuration information sent by a network device in the NR system, and can also receive second indication information sent by the network device, and determine based on the second indication information that the logged MDT configuration information is signaling-based logged MDT configuration information under the NR system.

In the above embodiment, the terminal can determine the type of logged MDT configuration information according to the second indication information sent by the network device. Especially in the LTE system, it can quickly determine whether the logged MDT configuration information belongs to the management-based logged MDT configuration information or the signaling-based logged MDT configuration information in the LTE system, which is convenient for coverage protection of different types of logged MDT configuration information and has high availability.

In some optional embodiments, referring to FIG. 4 , FIG. 4 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:

In step 401, when the logged minimized drive test configuration information corresponding to the first radio access technology RAT type is configured, the first information is reported to the network device.

The implementation of step 401 is similar to that of step 201 above, and will not be repeated here.

In step 402, the first information is cleared.

The implementation of step 402 is similar to that of step 301 above, and will not be described in detail here.

In the above embodiment, the terminal reports the first information to the network device, and the network device determines whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal according to the first information, thereby improving the coverage protection mechanism of the logged MDT configuration information on the terminal and improving the reliability of the terminal in executing logged MDT. At the same time, the first information on the terminal can be cleared in time to avoid excessive occupation of terminal resources, and the availability is high.

Next, the information transmission method provided by the present disclosure is introduced from the network device side.

The present disclosure provides an information transmission method, as shown in FIG5 , which is a flow chart of an information transmission method according to an embodiment, which can be executed by a network device, including but not limited to a base station, an access network device, etc., wherein the base station can be a 4G base station, a 5G base station or a future 6G base station, and the access network device can be a 4G access network device, a 5G access network device or a future 6G access network device, etc. The method may include the following steps:

In step 501, first information reported by a terminal is received; wherein the first information is reported when the terminal is configured with logged minimized drive test (MDT) configuration information.

In the embodiments of the present disclosure, logged MDT configuration information may refer to information used by a terminal to perform logged MDT measurements, which may be configured by a network device for the terminal, including but not limited to at least one of the following information: conditions for performing measurements (for example, performing when the terminal is in an idle state or an inactive state); measurement content (for example, the category of the public land mobile network PLMN that needs to be measured); timing for reporting measurement results (for example, reporting logged MDT measurement results each time the terminal enters a connected state), etc.

In an embodiment of the present disclosure, the first information can be used by a network device to determine whether to cover the logged MDT configuration information on a terminal. Further, the first information can be used by a network device to determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal.

In a possible implementation manner, the network device may receive the first information reported by the terminal through an RRC message.

Exemplarily, the RRC message includes but is not limited to an RRC recovery complete message, an RRC reconstruction complete message, an RRC connection establishment complete message, an RRC reconfiguration complete message, and the like.

Exemplarily, when the terminal is configured with logged MDT configuration information corresponding to the LTE system, the network device may receive first information reported by the terminal, and the first information may include the LTE system. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system. At this time, the network device may be a network device corresponding to any RAT type.

For example, the network device is a network device in an LTE system, and the network device receives first information reported by a terminal, and the first information may include RAT type information. Further, the first information indicates the first RAT type information. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system.

For another example, the network device is a network device in an NR system, and the network device receives first information reported by the terminal. The first information may include RAT type information. Further, the first information indicates the first RAT type information. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the LTE system.

For another example, the network device is a network device in an LTE system, and the network device receives first information reported by the terminal. The first information may include RAT type information. Further, the first information indicates the first RAT type information. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the NR system.

For another example, the network device is a network device in an NR system, and the network device receives first information reported by the terminal. The first information may include RAT type information. Further, the first information indicates the first RAT type information. After receiving the first information, the network device may determine that the terminal is configured with logged MDT configuration information corresponding to the NR system.

In one possible implementation, the network device may send logged MDT configuration information to the terminal so that the terminal can determine that it is configured with logged MDT configuration information.

The method by which a terminal determines that it is configured with logged MDT configuration information has been introduced on the terminal side and will not be repeated here.

In a possible implementation, the network device may receive the first information reported by the terminal in a manner including but not limited to the following manners:

In the first manner, the receiving terminal stores (or records) the first information in the designated variable and then reports the designated variable to the network device.

In this manner, the network device determines that the terminal performs storage (or recording). In one example, the specified variables include but are not limited to configuration variables and/or report variables.

For example, the network device receives the configuration variable reported by the terminal after storing (or recording) the first information in the configuration variable. The configuration variable includes but is not limited to VarLogMeasConfig.

For another example, the network device receives the report variable reported by the terminal after storing (or recording) the first information in the report variable. The report variable includes but is not limited to VarLogMeasReport.

For another example, the network device receives the configuration variables and report variables reported by the terminal after storing (or recording) the first information in the configuration variables and report variables, wherein the configuration variables include but are not limited to VarLogMeasConfig, and the report variables include but are not limited to VarLogMeasReport.

Exemplarily, when the terminal is configured with logged MDT configuration information corresponding to the first RAT type, after the terminal records the first information into a specified variable, the network device receives the first information reported by the terminal. The specified variable includes but is not limited to a configuration variable and/or a report variable, the configuration variable includes but is not limited to VarLogMeasConfig, and the report variable includes but is not limited to VarLogMeasReport. The first information includes RAT type information, and further, the first information includes first RAT type information, and the first RAT type includes an LTE system or an NR system.

The second method is to receive the first information reported by the terminal.

In this manner, the terminal does not need to perform storage (or recording), and the network device can directly receive the first information reported by the terminal.

Exemplarily, the network device receives the first information directly reported by the terminal.

In another possible implementation manner, the network device may receive first information reported by the terminal, where the first information includes RAT type information, and specifically may include first RAT type information.

In one example, the network device sends first indication information to the terminal so that the terminal determines the first RAT type.

In one example, the network device may send first indication information for determining the first RAT type to the terminal while sending logge MDT configuration information to the terminal.

In another example, the network device does not need to send the first indication information, and the terminal determines the first RAT type according to the wireless access mode of the terminal, that is, the terminal determines the first RAT type autonomously.

The manner in which the terminal determines the first RAT type has been introduced on the terminal side and will not be repeated here.

In a possible implementation manner, the network device may send a request message to the terminal, where the request message is used to request the terminal to report the first information.

The network device may receive the first information reported by the terminal based on the request message.

Of course, the terminal may also report the first information to the network device based on at least one reporting opportunity. The specific implementation method has been introduced on the terminal side and will not be repeated here.

In a possible implementation manner, the network device may receive the first information reported by the terminal in the following manner:

In a first manner, the network device receives specific content of the first information reported by the terminal.

The first information includes RAT type information, specifically including first RAT type information, for example, the first information includes an LTE system or an NR system.

Exemplarily, the protocol defines the format of the RAT type indication field, and the network device receives the RAT type indication field directly reported by the terminal, thereby determining the first RAT type according to the RAT type indication field.

The format of the RAT Type Indication field is as follows:

sigLoggedMeasRatType-r18 ENUMERATED{nr,e-utra,spare1}OPTIONAL,--Need R

Exemplarily, the protocol defines the format of the LTE system indication field, that is, the LTE system indication field is used to indicate whether the first RAT type includes an LTE system, and the format of the LTE system indication field is as follows:

sigLoggedMeasLTEType-r18 BOOLEAN

sigLoggedMeasNRType-r18 BOOLEAN

In one possible implementation, the network device receives the above-mentioned indication field reported by the terminal, such as the RAT type indication field, the LTE system indication field, and the NR system indication field, and determines the content of the first information according to the field value corresponding to the indication field, wherein the first information may specifically include the first RAT type information.

For example, the network device receives the RAT type indication field reported by the terminal, and determines that the first RAT type includes LTE or NR according to the field value of the RAT type indication field.

For another example, the network device receives the LTE system indication field reported by the terminal. When the field value of the LTE system indication field is set to true, the network device determines that the first RAT type includes the LTE system. If the field value of the LTE system indication field is set to false, the network device determines that the first RAT type includes the NR system.

For another example, the network device receives the NR system indication field reported by the terminal, and the field value of the NR system indication field is set to true, then the network device determines that the first RAT type includes the NR system; if the field value of the NR system indication field is set to false, then the network device determines that the first RAT type includes the NR system.

In another possible implementation, the network device determines the content of the first information according to whether the terminal reports the above-mentioned LTE system indication field or the NR system indication field within a preset time period after accessing the network device. Further, the first information may specifically include the first RAT type information. The duration of the preset time period may be agreed upon by the protocol or configured by the network device, and this disclosure is not limited to this.

For example, the protocol stipulates the format of the above-mentioned LTE system indication field. If the network device receives the LTE system indication field reported by the terminal, the network device determines that the first RAT type includes the LTE system. If the network device does not receive the LTE system indication field reported by the terminal, the network device can determine that the first RAT type includes the NR system.

For another example, the protocol stipulates the above-mentioned NR system indication field. If the network device receives the NR system indication field reported by the terminal, the network device determines that the first RAT type includes the NR system. If the network device does not receive the NR system indication field reported by the terminal, the network device can determine that the first RAT type includes the LTE system.

In the second manner, the network device receives the first information sent by the terminal in an implicit indication manner.

Exemplarily, the network device receives first information sent by the terminal, and the first information includes whether the logged MDT configuration information belongs to inter-RAT configuration information.

In a possible implementation, the protocol specifies the format of the inter-RAT indication field, which is set to true to indicate that the logged MDT configuration information belongs to the inter-RAT configuration information. The field is set to false to indicate that the logged MDT configuration information does not belong to the inter-RAT configuration information.

The format of the inter-RAT indication field is as follows:

sigLoggedMeasInterType-r18 BOOLEAN

For example, when the network device receives the inter-RAT indication field reported by the terminal, and the field value of the inter-RAT indication field is configured as true, the network device determines that the logged MDT configuration information belongs to the inter-RAT configuration information. If the field value of the inter-RAT indication field is configured as false, the network device determines that the logged MDT configuration information does not belong to the inter-RAT configuration information.

In another possible implementation, the protocol stipulates the format of the inter-RAT indication field, and the network device determines the content of the first information by whether the terminal reports the inter-RAT indication field within a preset period of time when accessing the network device. Specifically, the first information includes the first RAT type information. The duration of the preset period of time can be stipulated by the protocol or configured by the network device, and this disclosure does not limit this.

If the network device receives the inter-RAT indication field reported by the terminal within the preset period, the network device determines that the logged MDT configuration information belongs to the inter-RAT configuration information. If the network device does not receive the inter-RAT indication field reported by the terminal within the preset period, the network device determines that the logged MDT configuration information does not belong to the inter-RAT configuration information.

For example, the network device receives the inter-RAT indication field reported by the terminal within a preset period of time, and the network device determines that the logged MDT configuration information belongs to the inter-RAT configuration information based on the inter-RAT indication field. The network device can determine whether to cover the logged MDT configuration information under the inter-RAT system on the terminal based on the fact that the logged MDT configuration information belongs to the inter-RAT configuration information.

For another example, if the network device does not receive the inter-RAT indication field reported by the terminal within a preset period of time, and the network device belongs to a network device in the LTE system, the network device can determine that the logged MDT configuration information does not belong to the inter-RAT configuration information. Further, at this time, it is determined that the terminal is in the intra-LTE scenario, and the network device can determine whether to cover the logged MDT configuration information in the LTE system on the terminal based on the fact that the logged MDT configuration information does not belong to the inter-RAT configuration information.

In step 502, based on the first information, determine whether to overwrite the logged MDT configuration information on the terminal.

In the disclosed embodiment, the network device can decide whether to cover the logged MDT configuration information on the terminal based on the first information and the logged MDT measurement requirements, etc.

In one example, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information on the terminal with the management-based logged MDT configuration information.

For example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal through the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal with the management-based logged MDT configuration information under the NR system.

In another example, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information on the terminal with the management-based logged MDT configuration information.

For example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal with the management-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal with the management-based logged MDT configuration information under the LTE system.

For another example, in the intra-NR scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal with the management-based logged MDT configuration information under the NR system.

In another example, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information on the terminal with the signaling-based logged MDT configuration information.

For example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the signaling-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal with the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the LTE system on the terminal with the signaling-based logged MDT configuration information under the LTE system.

For another example, in the intra-NR scenario, the network device can determine, based on the first information, whether to overwrite the management-based logged MDT configuration information under the NR system on the terminal with the signaling-based logged MDT configuration information under the NR system.

In another example, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information on the terminal with the signaling-based logged MDT configuration information.

For example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal with the signaling-based logged MDT configuration information under the NR system.

For another example, in an inter-RAT scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal through the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-LTE scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the LTE system on the terminal with the signaling-based logged MDT configuration information under the LTE system.

For another example, in an intra-NR scenario, the network device can determine, based on the first information, whether to overwrite the signaling-based logged MDT configuration information under the NR system on the terminal with the signaling-based logged MDT configuration information under the NR system.

In one possible implementation, the first information includes first RAT type information corresponding to the logged MDT configuration information, and the network device can determine whether to cover the logged MDT configuration information on the terminal based on the first RAT type.

Exemplarily, whether in an inter-RAT, intra-LTE or intra-NR scenario, the network device determines whether to overwrite the logged MDT configuration information on the terminal depending on the first RAT type.

For example, the first RAT type includes an LTE system, and the network device determines logged MDT configuration information on the coverage terminal. The new logged MDT configuration information sent by the network device may be signaling-based logged MDT configuration information or management-based logged MDT configuration information, and the original logged MDT configuration information on the terminal may be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

For another example, the first RAT type includes an LTE system. In order to improve the performance of logged MDT in the LTE system, the network device determines not to overwrite the original logged MDT configuration information on the terminal. The original logged MDT configuration information on the terminal may be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

For example, the first RAT type includes an NR system, and the network device can determine the logged MDT configuration information on the coverage terminal. The new logged MDT configuration information sent by the network device can be the logged MDT configuration information based on signaling or the logged MDT configuration information based on management, and the original logged MDT configuration information on the terminal can be the logged MDT configuration information based on signaling or the logged MDT configuration information based on management.

For another example, the first RAT type includes an NR system. In order to improve the performance of logged MDT in the NR system, the network device determines not to overwrite the original logged MDT configuration information on the terminal. The original logged MDT configuration information on the terminal may be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

In another possible implementation, the first information includes first RAT type information corresponding to the logged MDT configuration information, and the network device can jointly determine whether to cover the logged MDT configuration information on the terminal based on its own RAT type (i.e., the specified RAT type) and the first RAT type.

In one example, when the RAT type of the network device is different from the first RAT type, in order to ensure that the terminal performs logged MDT more accurately in the current RAT cell, the network device can determine the logged MDT configuration information on the coverage terminal.

For example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device can determine that the management-based logged MDT configuration information under the NR system covers the signaling-based logged MDT configuration information under the LTE system on the terminal.

For another example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device can determine that the management-based logged MDT configuration information under the NR system covers the management-based logged MDT configuration information under the LTE system on the terminal.

For another example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device can determine that the signaling-based logged MDT configuration information under the NR system covers the management-based logged MDT configuration information under the LTE system on the terminal.

For another example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device can determine that the signaling-based logged MDT configuration information under the NR system covers the signaling-based logged MDT configuration information under the LTE system on the terminal.

Of course, a similar method can be used when a terminal moves from an NR cell to an LTE cell. I will not go into details here. That is, the network device can ignore the logged MDT configuration information on the terminal and directly overwrite the logged MDT configuration information corresponding to the original RAT type on the terminal based on the logged MDT configuration information corresponding to the current RAT type.

In another example, when the RAT type of the network device is different from the first RAT type, the network device can determine not to overwrite the logged MDT configuration information on the terminal, that is, let the terminal still execute logged MDT according to the originally configured logged MDT configuration information.

For example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device can determine that the signaling-based logged MDT configuration information under the LTE system on the terminal is not covered.

For another example, in an inter-RAT scenario, when a terminal moves from an LTE cell to an NR cell, the network device may determine that the management-based logged MDT configuration information under the LTE system on the terminal is not covered.

For another example, in an inter-RAT scenario, when a terminal moves from an NR cell to an LTE cell, the network device may determine that the management-based logged MDT configuration information under the NR system on the terminal is not covered.

For another example, in an inter-RAT scenario, when a terminal moves from an NR cell to an LTE cell, the network device can determine that the signaling-based logged MDT configuration information under the NR system on the terminal is not covered.

That is, when the RAT type is different, the network device ensures to protect the logged MDT configuration information corresponding to the original RAT type on the terminal. At this time, the network device will not send new logged MDT configuration information to overwrite the original logged MDT configuration information on the terminal.

In another example, when the RAT type of the network device is the same as the first RAT type, in order to save network device signaling resources, the network device may determine not to overwrite the logged MDT configuration information on the terminal, that is, to allow the terminal to still execute logged MDT according to the originally configured logged MDT configuration information.

For example, the RAT type corresponding to the network device is the LTE system, and the first RAT type includes the LTE system, that is, it is currently in an intra-LTE scenario. The network device can determine that the logged MDT configuration information under the LTE system on the terminal is not covered, wherein the logged MDT configuration information on the terminal is signaling-based logged MDT configuration information or management-based logged MDT configuration information.

In another example, when the RAT type of the network device is the same as the first RAT type, in order to enable the terminal to perform logged MDT measurements more timely and reliably, the network device can determine the logged MDT configuration information on the coverage terminal.

For example, the RAT type corresponding to the network device is the NR system, and the first RAT type includes the NR system, that is, it is currently in an intra-NR scenario. The network device can determine that the logged MDT configuration information under the NR system on the terminal is not covered, wherein the logged MDT configuration information on the terminal is signaling-based logged MDT configuration information or management-based logged MDT configuration information.

In another possible implementation, the first information includes first RAT type information corresponding to the logged MDT configuration information, and the network device can jointly determine whether to overwrite the logged MDT configuration information on the terminal based on the RAT type (i.e., the specified RAT type) corresponding to the new logged MDT configuration information to be issued and the first RAT type.

For example, no matter in the inter-RAT, intra-LTE or intra-NR scenario, the network device is about to send new logged MDT configuration information corresponding to the first RAT type to the terminal. At this time, the network device can determine to cover the original logged MDT configuration information corresponding to the first RAT type on the terminal. The new logged MDT configuration information sent by the network device can be signaling-based logged MDT configuration information or management-based logged MDT configuration information, and the original logged MDT configuration information on the terminal can be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

For another example, regardless of the inter-RAT, intra-LTE or intra-NR scenario, the network device is about to send new logged MDT configuration information corresponding to the first RAT type to the terminal. At this time, in order to save network device resources, the network device can determine to let the terminal continue to use the original logged MDT configuration information corresponding to the first RAT type, that is, the network device determines not to overwrite the original logged MDT configuration information corresponding to the first RAT type on the terminal. The original logged MDT configuration information on the terminal can be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

For another example, regardless of the inter-RAT, intra-LTE or intra-NR scenario, the network device is about to send new logged MDT configuration information corresponding to the specified RAT type to the terminal, and the specified RAT type is different from the first RAT type. At this time, in order to improve the reliability of logged MDT, the network device can determine to cover the original logged MDT configuration information corresponding to the first RAT type on the terminal. Among them, the new logged MDT configuration information sent by the network device can be signaling-based logged MDT configuration information or management-based logged MDT configuration information, and the original logged MDT configuration information on the terminal can be signaling-based logged MDT configuration information or management-based logged MDT configuration information.

For another example, regardless of the inter-RAT, intra-LTE or intra-NR scenario, the network device is about to send new logged MDT configuration information corresponding to the specified RAT type to the terminal, and the specified RAT type is different from the first RAT type. At this time, in order to cover and protect the original logged MDT configuration information on the terminal, the network device can determine not to cover the original logged MDT configuration information corresponding to the first RAT type on the terminal. Among them, the original logged MDT configuration information on the terminal can be signaling-based logged MDT configuration information or management-based logged MDT configuration information. In the above embodiment, the network device can determine whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal based on the first information reported by the terminal, improve the coverage protection mechanism of the logged MDT configuration information on the terminal, and improve the reliability of the terminal executing logged MDT.

In some optional embodiments, considering that the signaling-based logged MDT configuration information is the configuration information sent by the network device to a specific terminal in a targeted manner, it is more conducive to the terminal to accurately execute logged MDT than the management-based logged MDT configuration information. Therefore, in the case where only one set of logged MDT configuration information can be maintained on the terminal, in order to prevent the signaling-based logged MDT configuration information from being overwritten by the management-based logged MDT configuration information, resulting in the loss of logged MDT configuration information and logged MDT records, in R17, the signaling-based logged MDT coverage protection mechanism in the intra-NR scenario is supported.

Since the coverage protection mechanism of logged MDT based on signaling is applicable to intra-NR scenarios, that is, it is applicable to the movement of terminals between NR cells. Considering the terminal mobility, the terminal is likely to move from a cell under one wireless communication system to a cell under another wireless communication system, that is, the terminal is in an inter-RAT scenario (such as intra-LTE scenario or intra-NR scenario). How to protect the logged MDT configuration information on the terminal, especially the logged MDT configuration information based on signaling on the terminal, is an urgent problem to be solved.

It is understandable that in the intra-LTE scenario, for example, when a terminal moves from one cell under the LTE system to another cell under the LTE system, there is also a need to protect the logged MDT configuration information on the terminal, especially the signaling-based logged MDT configuration information on the terminal.

In an embodiment of the present disclosure, the terminal may report first information to the network device, and the first information may include type information of logged MDT configuration information, that is, the logged MDT configuration information is signaling-based logged MDT configuration information or association-based logged MDT configuration information.

The network device can determine whether to overwrite the logged MDT configuration information on the terminal based on the type information of the logged MDT configuration information.

In one example, each time the terminal enters a connected state, it can report first information to the network device through an RRC recovery completion message, where the first information is used to indicate whether valid signaling-based logged MDT configuration information or logged MDT records are stored (or recorded) on the terminal.

For example, the terminal reports the first information, and the first information includes sigLogMeasConfigAvailable=true. The network device determines, based on the first information, that valid signaling-based logged MDT configuration information is stored (or recorded) on the terminal.

For another example, the terminal reports first information, and the first information includes sigLogMeasConfigAvailable=false. The network device determines, based on the first information, that valid signaling-based logged MDT configuration information is not stored (or recorded) on the terminal. Accordingly, the network device can determine that management-based logged MDT configuration information is stored (or recorded) on the terminal.

In another example, each time the terminal enters the connected state, it can report first information to the network device through an RRC recovery completion message, and the first information directly indicates the type of logged MDT configuration information.

For example, the terminal reports the first information, and the first information includes type #1. The network device can determine, based on the protocol agreement, that the logged MDT configuration information corresponding to type #1 is the logged MDT configuration information based on signaling.

For another example, the terminal reports the first information, and the first information includes type #2. The network device can determine, based on the protocol agreement, that the logged MDT configuration information corresponding to type #2 is the management-based logged MDT configuration information.

In the disclosed embodiment, the network device may determine whether to overwrite the logged MDT configuration information on the terminal only based on the type of the logged MDT configuration information.

In one example, in order to protect the logged MDT configuration information based on signaling, when the network device determines that the original logged MDT configuration information on the terminal is the logged MDT configuration information based on signaling, it is determined not to overwrite the logged MDT configuration information on the terminal.

For example, regardless of the inter-RAT, intra-LTE or intra-NR scenario, after the network device determines based on the first information that the original logged MDT configuration information on the terminal is signaling-based logged MDT configuration information, it can be determined that the logged MDT configuration information on the terminal will not be overwritten.

In another example, when the network device determines that the original logged MDT configuration information on the terminal is based on the managed logged MDT configuration information, it determines to overwrite the logged MDT configuration information on the terminal.

For example, regardless of the inter-RAT, intra-LTE or intra-NR scenario, after the network device determines based on the first information that the original logged MDT configuration information on the terminal is the management-based logged MDT configuration information, it can determine to overwrite the logged MDT configuration information on the terminal. Further, the network device can send new logged MDT configuration information to the terminal, thereby overwriting the original logged MDT configuration information on the terminal.

In some optional embodiments, the first information may include but is not limited to at least one of the following: first RAT type information corresponding to the logged MDT configuration information; type information of the logged MDT configuration information.

When the first information only includes the first RAT type information, the network device may determine whether to overwrite the logged MDT configuration information on the terminal in the manner shown in FIG5 . The specific determination method has been introduced in the embodiment shown in FIG5 and will not be repeated here.

When the first information only includes the type information of the logged MDT configuration information, the network device can use the above method to determine whether to cover the logged MDT configuration information on the terminal based only on the type information of the logged MDT configuration information. The specific determination method has been introduced in the above embodiment and will not be repeated here.

When the first information includes the first RAT type information and the type information of the logged MDT configuration information, the network device may adopt but is not limited to the following methods to jointly determine whether to cover the logged MDT configuration information on the terminal:

In the first method, the network device determines whether to overwrite the logged MDT configuration information on the terminal based on the first RAT type and the type of the logged MDT configuration information.

For example, the first RAT type includes an LTE system, and the logged MDT configuration information is logged MDT configuration information based on signaling. At this time, the network device determines not to overwrite the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an NR system, and the logged MDT configuration information is logged MDT configuration information based on signaling. At this time, the network device determines not to overwrite the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an LTE system, and the logged MDT configuration information is logged MDT configuration information based on signaling. At this time, the network device determines the logged MDT configuration information on the coverage terminal.

For another example, the first RAT type includes an NR system, and the logged MDT configuration information is logged MDT configuration information based on signaling. At this time, the network device determines the logged MDT configuration information on the coverage terminal.

For example, the first RAT type includes an LTE system, and the logged MDT configuration information is management-based logged MDT configuration information. At this time, the network device determines not to overwrite the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an NR system, and the logged MDT configuration information is management-based logged MDT configuration information. At this time, the network device determines not to overwrite the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an LTE system, and the logged MDT configuration information is management-based logged MDT configuration information. At this time, the network device determines the logged MDT configuration information on the coverage terminal.

For another example, the first RAT type includes an NR system, and the logged MDT configuration information is management-based logged MDT configuration information. At this time, the network device determines the logged MDT configuration information on the coverage terminal.

In the second method, the network device determines whether to overwrite the logged MDT configuration information on the terminal based on the first RAT type, the type of logged MDT configuration information and other information.

Other information here includes but is not limited to the RAT type of the network device and the RAT type corresponding to the new logged MDT configuration information that the network device is about to send.

For example, the first RAT type includes an LTE system, the RAT type of the network device includes an NR system, the logged MDT configuration information is logged MDT configuration information based on signaling, and the network device determines the logged MDT configuration information on the coverage terminal.

For another example, the first RAT type includes an LTE system, the logged MDT configuration information is signaling-based logged MDT configuration information, the RAT type corresponding to the new logged MDT configuration information includes an NR system, and the network device determines not to cover the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an LTE system, the logged MDT configuration information is logged MDT configuration information based on signaling, the RAT type corresponding to the new logged MDT configuration information includes an NR system, and the network device determines not to overwrite the logged MDT configuration information on the terminal.

For another example, the first RAT type includes an LTE system, the RAT type of the network device includes an NR system, the logged MDT configuration information is signaling-based logged MDT configuration information, the RAT type corresponding to the new logged MDT configuration information includes an NR system, and the network device determines not to overwrite the logged MDT configuration information on the terminal.

The above is only an exemplary description. In the inter-RAT, intra-LTE or intra-NR scenarios, the scheme in which the first information includes other information should fall within the scope of protection of the present disclosure. In addition, the scheme in which the network device determines whether to cover the logged MDT configuration information on the terminal based on the first information should fall within the scope of protection of the present disclosure.

In the above embodiments, the coverage protection mechanism of logged MDT configuration information can be improved, especially the coverage protection mechanism of logged MDT configuration information based on signaling can be improved, so as to improve the reliability of the terminal executing logged MDT.

In some optional embodiments, referring to FIG. 6 , FIG. 6 is a flow chart of an information transmission method according to an embodiment, which may be applicable to the network architecture shown in FIG. 1 , and may include the following steps:

In step 601, when the terminal 101 is configured with logged MDT configuration information, it reports the first information to the network device 102.

The implementation of step 601 is similar to that of step 201 above, and will not be repeated here.

In step 602, the network device 102 determines whether to overwrite the logged MDT configuration information on the terminal 101 based on the first information.

The implementation of step 602 is similar to that of step 502, and will not be described in detail here.

In step 603, the terminal 101 clears the first information.

The implementation of step 603 is similar to that of step 301 above, and will not be described again here.

In a possible implementation, the terminal 101 is configured with signaling-based logged MDT configuration information corresponding to the first RAT type. The first RAT type includes an LTE system or an NR system. In this embodiment, assuming that the first RAT type includes an LTE system, the terminal 101 can report the first information to the network device 102, and the network device 102 can be a network device in the NR system. Further, the first information can include the first RAT type information.

After receiving the first information, the network device 102 in the NR system determines whether to overwrite the signaling-based logged MDT configuration information on the terminal with the management-based logged MDT configuration information, or determines whether to overwrite the signaling-based logged MDT configuration information on the terminal with the signaling-based logged MDT configuration information.

If the network device 102 in the NR system determines the signaling-based logged MDT configuration information corresponding to the LTE system on the coverage terminal, the network device 102 in the NR system can send the logged MDT configuration information corresponding to the NR system to the terminal.

It should be noted that, when receiving logged MDT configuration information sent by the network device 102' (not shown in Figure 1) in the LTE system, the terminal 101 can receive second indication information sent by the network device 102' in the LTE system, and determine, based on the second indication information, that the logged MDT configuration information belongs to signaling-based logged MDT configuration information.

The terminal 101 can determine, based on the first indication information sent by the network device 102' in the LTE system, that the first RAT system includes the LTE system, that is, the logged MDT configuration information corresponds to the LTE system.

Alternatively, the terminal 101 may determine, based on the wireless access method, that the first RAT system includes an LTE system, that is, the logged MDT configuration information corresponds to the LTE system.

The terminal 101 may record the first information to the designated variable and then report the first information to the network device 102. Alternatively, the terminal 101 may not perform the recording action and directly report the first information to the network device 102. The designated variable includes but is not limited to a configuration variable and/or a report variable.

The scheme of reporting the first information to the network device when the reporting opportunity is reached has been introduced in the above embodiment and will not be repeated here.

Of course, when reporting the first information, the terminal 101 may report the specific content of the first information to the network device 102. Alternatively, the terminal 101 sends the first information to the network device 102 in an implicit indication manner. The specific manner has been introduced in the above embodiment and will not be repeated here.

The specific method has been introduced in the above embodiment and will not be repeated here.

In the above embodiment, the terminal is configured with logged MDT measurement configuration information corresponding to the first RAT type, and the terminal can report the first information to the network device, and the network device determines whether to cover the logged MDT configuration information on the terminal through the first information. The terminal can report the first information to the network device, so that the network device determines whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal, improves the coverage protection mechanism of the logged MDT configuration information on the terminal, and improves the reliability of the terminal executing logged MDT.

In some optional embodiments, referring to FIG. 7 , FIG. 7 is a flow chart of an information transmission method according to an embodiment, which may be applicable to the network architecture shown in FIG. 1 , and may include the following steps:

Step 701: A first network device sends logged MDT configuration information to a terminal, wherein the logged MDT configuration information corresponds to a first RAT type.

Exemplarily, the first RAT type includes an NR system or an LTE system.

Exemplarily, the logged MDT configuration information includes signaling-based logged MDT configuration information, or management-based logged MDT configuration information.

In some examples, the first network device sends a first message to the terminal, and the first message includes logged MDT configuration information and a first RAT type, then it is determined that the logged MDT configuration information corresponds to the first RAT type. Alternatively, the logged MDT configuration information includes the first RAT type, then it is determined that the logged MDT configuration information corresponds to the first RAT type.

For other contents of this step, please refer to the description of related contents in other embodiments above, which will not be repeated here.

In some other examples, the terminal may also receive first indication information sent by the first network device, where the first indication information is used to indicate that the logged MDT configuration information corresponds to a first RAT type.

In some other examples, the terminal may determine that the logged MDT configuration information corresponds to the first RAT type based on that the wireless access method between the terminal and the first network device is the first RAT type.

Step 702: When a specified condition is met, the terminal sends first information to the second network device.

The second network device may be the same as or different from the first network device. Further, the second network device may correspond to the same RAT type as the first network device, or the second network device may correspond to different RAT types than the first network device.

In one possible implementation, the terminal satisfies the specified condition including that when the terminal is configured with logged MDT configuration information, the terminal reports the first information to the second network device.

In a possible implementation, the terminal meeting the specified condition means reaching a reporting opportunity. At this time, the terminal reports the first information to the second network device.

The reporting opportunity may include but is not limited to at least one of the following: the terminal enters a connected state (for example, each time entering a connected state); residing in a cell of a second RAT type, where the second RAT type is different from the first RAT type (for example, the second network device is a second RAT type, and the second RAT type is different from the first RAT type); receiving a request message sent by the second network device, the request message is used to request the terminal to report the first information.

Optionally, the first information may include the RAT type corresponding to the existing logged MDT configuration information of the terminal, that is, the first RAT type information.

Optionally, the first information may include at least one of the following: first RAT type information; type information of logged MDT configuration information.

Step 703: The second network device determines whether to overwrite the logged MDT configuration information on the terminal based on the first information.

In one example, the second network device can determine whether to overwrite the logged MDT configuration information on the terminal based on the first RAT type information in the first information.

Exemplarily, regardless of the inter-RAT, intra-LTE or intra-NR scenario, the second network device can determine whether to cover the logged MDT configuration information on the terminal based on the first RAT type in the first information.

In another example, the second network device can jointly determine whether to overwrite the logged MDT configuration information on the terminal based on its own RAT type and the first RAT type.

In one example, when the RAT type of the second network device is different from the first RAT type, in order to ensure that the terminal performs logged MDT more accurately in the current RAT cell, the second network device can determine the logged MDT configuration information on the coverage terminal.

In another example, when the RAT type of the second network device is different from the first RAT type, the second network device can determine not to overwrite the logged MDT configuration information on the terminal, that is, let the terminal still execute logged MDT according to the originally configured logged MDT configuration information.

That is, when the RAT type is different, the second network device ensures to protect the logged MDT configuration information corresponding to the original RAT type on the terminal. At this time, the second network device will not send new logged MDT configuration information to overwrite the original logged MDT configuration information on the terminal.

In another example, when the RAT type of the second network device is the same as the first RAT type, in order to save network device signaling resources, the second network device may determine not to overwrite the logged MDT configuration information on the terminal, that is, to allow the terminal to still execute logged MDT according to the originally configured logged MDT configuration information.

In another example, when the RAT type of the second network device is the same as the first RAT type, in order to enable the terminal to perform logged MDT measurements more timely and reliably, the second network device can determine the logged MDT configuration information on the coverage terminal.

In another example, the second network device can jointly determine whether to overwrite the logged MDT configuration information on the terminal based on the RAT type corresponding to the new logged MDT configuration information to be issued and the first RAT type.

In another possible implementation, the first information may include type information of logged MDT configuration information.

The second network device can determine whether to overwrite the logged MDT configuration information on the terminal based on the type information of the logged MDT configuration information.

In one example, each time the terminal enters a connected state, it can report first information to the second network device through an RRC recovery completion message, where the first information is used to indicate whether valid signaling-based logged MDT configuration information or logged MDT records are stored (or recorded) on the terminal.

In another example, each time the terminal enters the connected state, the terminal may report the first information to the second network device through an RRC message, where the first information directly indicates the type of logged MDT configuration information. The RRC message includes but is not limited to an RRC recovery complete message, an RRC reestablishment complete message, an RRC connection establishment complete message, an RRC reconfiguration complete message, etc.

In an embodiment of the present disclosure, the second network device can determine whether to overwrite the logged MDT configuration information on the terminal based on the type of the logged MDT configuration information.

In one example, in order to protect the logged MDT configuration information based on signaling, when the second network device determines that the original logged MDT configuration information on the terminal is logged MDT configuration information based on signaling, it is determined not to overwrite the logged MDT configuration information on the terminal.

In another example, when the second network device determines that the original logged MDT configuration information on the terminal is based on the managed logged MDT configuration information, it determines to overwrite the logged MDT configuration information on the terminal.

In another possible implementation, the first information may include first RAT type information corresponding to the logged MDT configuration information, and type information of the logged MDT configuration information.

The second network device may adopt, but is not limited to, the following methods to jointly determine whether to overwrite the logged MDT configuration information on the terminal:

In the first method, the second network device determines whether to overwrite the logged MDT configuration information on the terminal based on the first RAT type and the type of the logged MDT configuration information.

In the second method, the second network device determines whether to overwrite the logged MDT configuration information on the terminal based on the first RAT type, the type of logged MDT configuration information and other information.

Other information here includes but is not limited to the RAT type corresponding to the second network device and the RAT type corresponding to the new logged MDT configuration information to be issued by the second network device.

The above is only an exemplary description. In the inter-RAT, intra-LTE or intra-NR scenarios, schemes in which the first information includes other information should fall within the scope of protection of the present disclosure. In addition, schemes in which the second network device determines whether to cover the logged MDT configuration information on the terminal based on the first information should fall within the scope of protection of the present disclosure.

Step 704: When the second network device determines to cover the logged MDT configuration information on the terminal, it sends new logged MDT configuration information to the terminal.

Step 704 is optional. When the second network device determines not to overwrite the logged MDT configuration information on the terminal, step 704 may not be executed.

In this step, the terminal receives new logged MDT configuration information and can overwrite the original logged MDT configuration information based on the new logged MDT configuration information.

In the above embodiments, the coverage protection mechanism of the logged MDT configuration information on the terminal is improved, thereby improving the reliability of the terminal executing logged MDT.

(c) The first timer on the terminal is in running state; wherein, the first timer is used to determine whether the logged MDT configuration information is valid.

As a possible implementation manner: in response to the terminal receiving the logged MDT configuration information sent by the network device, the terminal reports the first RAT type corresponding to the Logged MDT configuration information to the network device.

As a possible implementation method: in response to the terminal recording the Logged MDT measurement result, the terminal reports the first RAT type corresponding to the Logged MDT configuration information to the network device.

As a possible implementation method, in response to the terminal receiving the Logged MDT configuration information sent by the network and the first timer on the terminal, such as the T330 timer, is running, the terminal reports the first RAT type corresponding to the Logged MDT configuration information to the network device.

When all logged MDT records are reported to the network device, the first information is cleared;

When the end time point of the preset time period is reached, clearing the first information;

Based on the above description, logged MDT configuration information includes but is not limited to:

Management-based logged MDT configuration information;

Based on the above description, the manner in which the terminal reports the first information, specifically, the manner in which the terminal reports the first RAT type may include:

(a) The RAT type indication field, LTE system indication field or NR system indication field indicates whether the logged MDT configuration information corresponds to the LTE system or the NR system.

The inter-RAT indication field indicates whether the Logged MDT configuration information belongs to inter-RAT configuration information.

The above indication field may be an explicit indication, or may be an implicit indication by whether the indication field is carried. For example, if it is an explicit indication, the format of the RAT type indication field is as follows:

sigLoggedMeasRatType-r18 ENUMERATED{nr,e-utra,spare1}OPTIONAL,--Need R The field value of the RAT type indication field is used to indicate whether the logged MDT configuration information corresponds to the LTE system or the NR system.

If it is an explicit indication, the format of the LTE system indication field is as follows:

sigLoggedMeasLTEType-r18 BOOLEAN

If the field value of the LTE system indication field is set to true, it is used to indicate that the logged MDT configuration information belongs to the inter-RAT configuration information. If the field value of the LTE system indication field is set to false, it is used to indicate that the logged MDT configuration information does not belong to the inter-RAT configuration information.

If it is an implicit indication, the format of the inter-RAT indication field is as follows:

sigLoggedMeasInterType-r18 BOOLEAN

This field is set to true to indicate that the logged MDT configuration information belongs to inter-RAT configuration information. This field is set to false to indicate that the logged MDT configuration information does not belong to inter-RAT configuration information.

If it is an implicit indication, the format of the RAT type indication field is as follows:

sigLoggedMeasRatType-r18 ENUMERATED{true}OPTIONAL

Further, the following is explained:

If the content reported by the terminal contains the above-mentioned LTE system indication field, the network device determines that the terminal is configured with the logged MDT configuration information corresponding to the LTE system. Otherwise, the network device determines that the terminal is configured with the logged MDT configuration information corresponding to the NR system.

If the content reported by the terminal includes the above-mentioned inter-RAT indication field, the network device determines that the terminal is configured with the logged MDT configuration information corresponding to the inter-RAT system. Otherwise, the network device determines that the terminal is not configured with the logged MDT configuration information corresponding to the inter-RAT system.

In embodiment 2, the above information transmission method comprises the following steps:

Step 1, terminal 101 receives logged MDT configuration information sent by network device 102.

Optionally, the network device 102 informs the terminal 101 of the first RAT type corresponding to the Logged MDT configuration through the first indication information.

Among them, logged MDT configuration information includes but is not limited to signaling-based logged MDT configuration information and management-based logged MDT configuration information.

The first RAT type includes but is not limited to NR, LTE (or Evolved UMTS Terrestrial Radio Access Network E-URAN).

Step 2: Terminal 101 determines the first RAT type corresponding to the logged MDT configuration information.

The determination method includes but is not limited to any one of the following: the terminal 101 determines the first RAT type according to the first indication information sent by the network device 102; the terminal 101 determines the first RAT type according to the wireless access method.

In this embodiment, the network device 102 sends the first indication information, and the terminal 101 determines the first RAT type according to the first indication information.

In other possible implementations, when the terminal 101 determines the first RAT type according to the wireless access method, exemplarily, the terminal receives logged MDT configuration information in the NR cell, then the terminal determines that the first RAT type corresponding to the logged MDT configuration information is the NR system.

In step 3 (step 3 is optional), the terminal 101 records the first RAT type into a designated variable.

Furthermore, the configuration variables include but are not limited to VarLogMeasConfig. In response to the network device 102 sending the first indication information indicating the first RAT type while sending the logged MDT configuration information, the terminal 101 records the first RAT type in the logged MDT configuration variable (VarLogMeasConfig).

Furthermore, the reporting variables include but are not limited to VarLogMeasReport. In response to determining the first RAT type of the logged MDT configuration information according to the wireless access method, the terminal 101 records the first RAT type in the Logged MDT reporting variable (VarLogMeasReport).

Exemplarily, if the logged MDT configuration variable (VarLogMeasConfig) includes the first RAT type, the terminal 101 may record the first RAT type in the Logged MDT report variable (VarLogMeasReport).

If the terminal determines the first RAT type based on the wireless access type, that is, when the terminal receives the logged MDT configuration information in the NR or LTE cell, the first RAT type can be recorded in the logged MDT report variable (VarLogMeasReport).

Of course, the specified variables may also include other configuration variables or other report variables, which is not limited in the present disclosure.

Step 4: Terminal 101 reports first information to network device 102.

It is understandable that if the above step 3 is not performed, the terminal 101 does not need to record the first information, and can directly report the first information to the network device 102 through step 4.

In this embodiment, the first information includes the first RAT type information corresponding to the Logged MDT configuration information.

In one example, each time the terminal 101 enters the connected state, the first RAT type is reported to the network device 102. For example, the terminal reports the first RAT type to the network device 102 via an RRC connection establishment complete message, an RRC reconfiguration complete message, an RRC reconstruction complete message, or an RRC recovery complete message.

In one example, when the terminal 101 camps on the inter-RAT cell, the first RAT type is reported to the network device 102 .

In one example, when terminal 101 receives a request message from network device 102 requesting terminal 101 to report first information, terminal 101 reports the first RAT type to network device 102 .

The combination situation will not be described here in detail. For example, when the terminal 101 resides in the Inter-RAT cell, each time the terminal 101 enters the connected state, the terminal 101 reports the first RAT type to the network device 102.

Step 5 (Step 5 is optional), in response to the terminal recording the first information, when at least one of the following conditions is met, the terminal clears the first information:

When all logged MDT records are reported to the network device 102, the first information is cleared;

When the end time point of the preset time period is reached, for example, time point t1 after 48 hours, the first information is cleared;

When the terminal 101 receives the logged MDT configuration information under the new RAT sent by the network device 102, the first information is cleared.

The combination situation will not be described here. For example, when the logged MDT configuration information expires and all logged MDT records are reported to the network device 102, the terminal 101 clears the first information, and the first information includes the first RAT type information.

In the above embodiment, when the terminal is configured with logged MDT measurement configuration information corresponding to the first RAT type, the terminal can report the first information to the network device, and the network device determines whether to cover the logged MDT configuration information on the terminal through the first information. In the inter-RAT or intra-LTE scenario, the terminal can report the first information to the network device, so that the network device determines whether to cover the logged MDT configuration information corresponding to the first RAT type on the terminal, improves the coverage protection mechanism of the logged MDT configuration information on the terminal, and improves the reliability of the terminal executing logged MDT.
