In some network configurations, a network device may include Centralized Unit (CU) nodes and Distributed Unit (DU) nodes, which may also be geographically separated.

The following describes the related art and terms referred to in this application.

1. Mobile robustness optimized MRO mechanism

In order to reduce the problems of switching too early, too late, ping-pong switching and the like in the switching of same-frequency switching, different-system switching and the like caused by unreasonable network parameter setting, the system supports an MRO mechanism, which is an important mechanism of network self-optimization, after a terminal device generates a situation (such as switching failure, radio link failure in a target cell, random access success and the like) related to mobility, failure information, success information or general statistical information related to the mobility can be reported to a network, and the network device can perform autonomous analysis and network parameter optimization according to the reported information of the terminal device.

2. Failure/success information for UE

The success information of the UE may include Random Access (RA) success information, and the failure information of the UE may include, but is not limited to, information related to a failure event:

cell establishment/recovery failure (CEF), radio Link Failure (RLF), handover failure (HOF), RA failure (RA failure), serving cell change failure (serving cell change failure), and the like.

The serving cell may be a primary cell (PSCell), a primary secondary cell (PSCell), or a secondary cell (SCell).

The failure/success information of the UE is not configured on the network side, and when the UE detects a failure event or a success event, the UE records the relevant measurement statistical information, and if the failure event is detected, also records the failure type, and reports each measurement statistical information to the network side at a proper time, so that the network side can perform network optimization based on the received measurement statistical information sent by the UE, for example, the measurement statistical information is used for subsequent optimization of MRO and the like or is used as a base station algorithm reference. Measurement statistics may include, but are not limited to:

cell/beam information including cell-level identification information or beam identification information of the source cell, the target cell, the local cell, the neighboring cell, etc., and further including measurement result information, e.g., signal strength and/or signal quality of the cell, beam, etc.;

time information, which may include the time interval between the occurrence of a failure event and the next successful access, the time interval between the occurrence of a failure and the reporting of measurement statistics, the time interval between the receipt of configuration information and the occurrence of a failure event, the time interval between the last successful access and the occurrence of the failure event, and so on;

-random access related information including random access resource information, number of attempted accesses, measurement threshold information, contention resolution information, etc.;

failure cause information may also be included for failure events, such as T310 timeout, RLC maximum number of retransmissions, etc.;

-geographical location information.

After the UE records and stores the available measurement statistical information of the failure event/success event, the result is stored for a period of time until the result is reported to the network or the UE deletes the result by itself after overtime.

If the UE enters the connected state or moves to a new cell, the UE may report an available indication (available indicator) of whether measurement statistical information corresponding to the failure event is available to the network through an RRC signaling, and the available indication may be divided into an RLF result available indication, an HOF result available indication, which occur in the connected state, or a CEF result available indication, which occurs in the unconnected state, according to the type of the failure event. An available indicator (available indicator) may not be needed when a success event only includes RA success. After the network obtains the available indication, if the network needs to further obtain the measurement statistical information of the success event or the failure event, a UE information request (e.g., a UEInformationRequest) message may be sent to the UE through the network device to request the measurement statistical information recorded by the UE. Accordingly, after receiving the UE information request message, the UE may send a UE information response (e.g., UE information response) message to the network, where the message includes measurement statistics recorded by the UE.

3. General statistical information

The general statistical information of the UE may include, but is not limited to, measurement information obtained by performing Radio Resource Management (RRM) measurement when the terminal device is in a non-connected state (e.g., an IDLE (IDLE) state and an INACTIVE (INACTIVE) state), MDT (logged MDT) information obtained by performing minimization of drive-tests (MDT) measurement, and stored UE movement history information, and the UE may report the general statistical information to the network side at a suitable time for subsequent optimization of MRO and the like or serving as a reference for a base station algorithm. The recording content and reporting mode may be similar to the failure information/success information. After the terminal device moves to a cell or establishes a communication connection with a cell each time, the terminal device performs a UE movement history record (or stores UE movement history record information, which may also be referred to as a UE movement history record event), and records related information of the cell. The UE movement history record information comprises the relevant information of the cell recorded after the UE moves once or more.

4. Node (power saving) relaxation mechanism

Also referred to as measurement relaxation mechanism, the main purpose of which is to save power of the UE while ensuring certain UE performance. When the UE satisfies a certain condition, RRM mobility measurement for the cell and/or each neighboring cell may be relaxed, for example, a period of RRM measurement is lengthened, or measurement for the neighboring cell is stopped, so as to reduce a measurement frequency of the UE and reduce power consumption of the UE. When the UE looses the RRM measurement of the cell, it may be said that the UE is in a measurement relaxed state.

The network may send configuration information of the measurement relaxation state to the UE, and the UE may determine whether to enter the measurement relaxation state according to the configuration information of the measurement relaxation state. For example, the network may configure the UE to enter a measurement relaxed state while in a low mobility state and/or in a non-cell edge location.

For the low mobility state, the network may configure an evaluation duration for the UE to evaluate whether the UE is in the low mobility state and a threshold value for a change in signal strength (e.g., the signal strength may be a Reference Signal Receiving Power (RSRP)), and the UE may determine that the UE is in the low mobility state according to the change in signal strength within the evaluation duration being less than the threshold value.

For the non-cell edge position, the network may be configured to evaluate, by the UE, whether the signal strength (e.g., RSRP) and the signal quality (RSRQ) are at the non-cell edge position, and the UE compares a value of the signal strength, a value of the signal quality, and a corresponding threshold value to determine whether the signal strength, the signal quality, and the threshold value are at the non-cell edge position.

The network may also configure whether the UE performs measurement relaxation operations for high priority frequency points.

According to the foregoing description, in the case that the UE satisfies the condition of entering the measurement relaxation state, the UE will relax the RRM measurement of the local cell and/or the neighboring cell, for example, the RRM measurement period is extended or the RRM measurement is not performed, which may cause the UE to generate a mobility problem or to not replace a suitable cell in time, which may cause a situation of communication quality degradation or connection failure, and in addition, since the RRM measurement period is longer, the timeliness and accuracy of the measurement result are lower. However, the network may acquire the measurement statistical information recorded by the UE when needed, and at this time, the UE context information stored by the network node and related to the measurement relaxed state may have been released, so that the network cannot know the state where the UE records the measurement statistical information, and thus the network performs network self-optimization according to the measurement statistical information, and a situation that a network optimization direction is wrong, or even a network parameter is adjusted incorrectly occurs. Therefore, the UE informs the network whether the network is in a measurement relaxed state when recording the measurement statistical information, so that the accuracy of self optimization of the network can be improved.

The information transmission method provided by the present application is described below with reference to the drawings.

Example one

Fig. 2 is a schematic flowchart of an information transmission method according to an embodiment of the present application.

S201, when a specified event occurs, the terminal device determines statistical information and measurement relaxation information of the terminal device, wherein the measurement relaxation information is used for representing that the terminal device is in a measurement relaxation state when the specified event occurs.

When the terminal device enters a measurement relaxation state, if a specified event occurs to the terminal device, the terminal device records (in this application, the record may be stored, and is not described below) statistical information (or referred to as measurement statistical information) related to the specified event, and the terminal device also records measurement relaxation information corresponding to the specified event, where the measurement relaxation information is information of a measurement relaxation state in which the terminal device occurs when the specified event occurs.

By way of example and not limitation, the specified event may include, but is not limited to, one or more of the following:

initial connection establishment failure, connection recovery failure, radio link failure, handover failure, serving cell change failure, random access success, RRM measurement, performing minimization of drive test, MDT, or storing terminal device mobility history information.

The serving cell change failure may be a PCell change failure, a PSCell change failure, or an SCell change failure, which is not limited in the present application.

It should be noted that, the name of the specified event is not limited in the present application, for example, when the specified event is an initial connection setup failure, the occurrence of the specified event by the terminal device may be referred to as the occurrence of the initial connection setup failure by the terminal device. For another example, when the specified event is performing MDT, the occurrence of the specified event by the terminal device may be called that the terminal device performs MDT, or that the terminal device stores MDT information once.

Optionally, the network device sends configuration information for configuring the measurement relaxation state to the terminal device. Accordingly, the terminal device receives the configuration information from the network device, and determines to enter a measurement relaxation state according to the configuration information. The configuration information includes one or more of:

when the measurement relaxation state is triggered, the parameter value corresponding to the trigger type is used for representing a threshold for starting the measurement relaxation state by the terminal equipment when the trigger type is met;

a period for performing RRM measurements while the terminal device is in a measurement relaxation state.

For example, the configuration information may configure a trigger type of the measurement relaxation state, for example, the trigger type of the measurement relaxation state may include that the terminal device is in a low mobility state and/or in a non-cell edge location, and the configuration information may further configure a relevant parameter that the terminal device determines to enter the measurement relaxation state, such as one or more of an evaluation duration, a threshold value of signal strength, or a threshold value of signal quality. And the terminal equipment determines to enter a measurement relaxation state according to the configuration information.

Optionally, the determining, by the terminal device, measurement relaxation information specifically includes: the terminal device determines, as measurement relaxation information, a first cycle in which RRM measurement is performed or the determined execution of RRM measurement has stopped, in a case where the specified event occurs; wherein the first period is greater than a second period, and the second period is a period in which the RRM measurement is performed when the terminal device is in a non-measurement relaxed state.

In one embodiment, the measurement relaxation information includes indication information 1, and the indication information 1 is used for indicating that the terminal device is in a measurement relaxation state when a specified event occurs.

For example, the terminal device may record statistical information related to a specified event and record the indication information 1 in a case where the terminal device is in a measurement relaxation state at the time of occurrence of the specified event. If the terminal device is not in the measurement relaxation state when the specified event occurs, the terminal device does not record the indication information 1 corresponding to the specified event.

For another example, the terminal device may record statistical information related to a specific event when the terminal device is in a measurement relaxation state at the time of the specific event, and record the indication information 1 indicating that the terminal device is in the measurement relaxation state. If the terminal device is not in the measurement relaxed state when the specified event occurs, the terminal device may record the indication information 1 to indicate that the terminal device is not in the measurement relaxed state.

In another embodiment, the measured relaxation information comprises information on parameters related to the measured relaxation state.

Optionally, the parameter information related to measuring the relaxation state may include, but is not limited to, one or more of the following a to e:

a. the configuration information for configuring the measurement relaxation state;

b. triggering a trigger type for starting measurement of a relaxed state;

for example, the type of trigger triggering the terminal device to enter the measurement relaxation state is that the terminal device is in a low mobility state and/or the terminal device is in a non-cell edge location, and the measurement relaxation information may indicate the type of trigger.

For example: the terminal detects that it is in the low mobility state when a specified event occurs, and then triggers to enter into the measurement relaxation state, and then the low mobility state may be used as the measurement relaxation information or included in the measurement relaxation information. And then the statistical information and the statistical information are sent to the network equipment.

c. The parameter value of the trigger type is used for representing a threshold for starting a trigger measurement relaxation state by the terminal equipment when the trigger type is met;

for example, the parameter value includes one or more of a threshold value of signal strength, a threshold value of signal quality, or an evaluation duration corresponding to the trigger type.

If the trigger type recorded in the b is combined, under the condition recorded in the b, the terminal detects that the terminal is in a low mobility state when a specified event occurs, and can be directly triggered and started to enter a measurement relaxation state; however, with reference to the content described in c, the terminal detects that the terminal is in the low mobility state when the specified event occurs, and needs to detect a signal (taking signal detection as an example for description), and when the detected signal strength meets a threshold value of a measurement release state corresponding to the low mobility state, the terminal is triggered to start entering the measurement release state.

d. The terminal equipment measures the relaxation degree of the relaxation state;

optionally, the measurement relaxation degree comprises a period of RRM measurements when the terminal device is in a measurement relaxation state.

In one approach, the measurement relaxation information may include a period size of RRM measurement when the terminal device is in a measurement relaxation state.

In another manner, the measurement relaxation information may include a multiple of a period of RRM measurements when the terminal device is in the measurement relaxation state compared to a period of RRM measurements when the terminal device is not in the measurement relaxation state.

e. Time information related to measuring the relaxation state.

Optionally, the time information related to measuring the relaxation state comprises one or more of:

Optionally, the parameter information related to measuring the relaxation state may further include, but is not limited to, one or more of the following:

f. relaxing information of the measured first cell when the terminal device is in a measurement relaxed state;

for example, the terminal device may inform the network of at least one cell for which the terminal device specifically loosens measurements by the measurement relaxation information, and if the terminal device performs a relaxation measurement on the first cell, the measurement relaxation information may include identification information of the first cell. The cells in which the terminal device performs the relaxation measurement may include one or more cells of a PCell, PSCell, or SCell.

g. Triggering a measurement result of the first cell in a measurement relaxed state;

for example, the signal strength value measured by the terminal device is greater than the threshold value corresponding to the signal strength, it is determined that the terminal device is in the low mobility state and triggers the terminal device to enter the measurement relaxation state, and the measurement relaxation information includes the signal strength value obtained by the measurement. Or the signal strength value measured by the terminal equipment is larger than the threshold value corresponding to the signal strength, and the signal quality measured by the terminal equipment is larger than the threshold value corresponding to the signal quality, and if the terminal equipment is determined to be in the non-cell edge position and is triggered to enter the measurement relaxation state, the measurement relaxation information comprises the signal strength value and the signal quality value measured by the terminal equipment. But the application is not limited thereto.

In another embodiment, the measurement relaxation information includes the indication information 1 and parameter information related to the measurement relaxation state.

Optionally, the terminal device sends one or more pieces of reporting information to the network device, where the reporting information includes statistical information and measurement relaxation information related to a specific event determined by the terminal device for the specific event.

For example, if a specific event occurs before the terminal device sends the statistical information and the measurement relaxation information related to the specific event to the network (for example, the last specific event may be referred to as a first specific event, and the specific event occurring this time may be referred to as a second specific event), the terminal device records the statistical information related to the second specific event.

The second specified event is a specified event occurring at a different time than the first specified event, and the second specified event may be the same as or different from the first specified event in type. For example, the first specified event may be a handover failure event, and the second specified event may be a random access success event occurring after the handover failure event, or the first specified event may be a radio link failure event, and the second specified event may be a radio link failure event occurring again by the terminal device before statistical information related to the radio link failure event (i.e., the first specified event) and measurement relaxation state information are reported to the network device.

In one embodiment, the terminal device determines whether to record second measurement relaxation information according to whether the terminal device is in a measurement relaxation state when a second specified event occurs, wherein the second measurement relaxation information is information of the measurement relaxation state in which the terminal device is located when the second specified event occurs, and if the terminal device is in the measurement relaxation state, the second measurement relaxation information is recorded, and the second measurement relaxation information is used for indicating that the terminal device is in the measurement relaxation state, and the second measurement relaxation information includes indication information 2 and/or parameter information related to the measurement relaxation state. The indication information 2 is used to indicate that the terminal device is in a measurement relaxed state when the second specified event occurs. The related parameter information may include one or more of a to g described above.

And if the terminal equipment is not in the measurement relaxation state, not recording the second measurement relaxation information.

For example, after the terminal device has a first specified event and before a second specified event occurs, the terminal device exits the measurement relaxation state, or cancels performing the measurement relaxation, and then the terminal device determines that the terminal device is not in the measurement relaxation state after the second specified event occurs, and then the terminal device records only the statistical information related to the second specified event.

For another example, the terminal device is still in the measurement relaxation state when the second specified event occurs, and then the terminal device records statistical information related to the second specified event and second measurement relaxation information after the second specified event occurs, where the second measurement relaxation information is used to indicate that the terminal device is in the measurement relaxation state when the second specified event occurs.

In another embodiment, the terminal device further records second measurement relaxation information after the second specified event occurs. And if the terminal equipment is in the measurement relaxation state, the second measurement relaxation information is used for indicating that the terminal equipment is in the measurement relaxation state, and the second measurement relaxation information comprises indication information 2 and/or relevant parameter information of the measurement relaxation state. And if the terminal equipment is not in the measurement relaxation state, the second measurement relaxation information is used for indicating that the terminal equipment is not in the measurement relaxation state.

That is, every time a specific event occurs to the terminal device, the terminal device records statistical information related to the specific event that occurs once, and the terminal device also records measurement relaxation information corresponding to each event, which is used for indicating whether the terminal device is in a measurement relaxation state when the corresponding event occurs.

For example, after the terminal device has a first specified event and before a second specified event occurs, the terminal device exits the measurement relaxation state, and then the terminal device determines that the terminal device is not in the measurement relaxation state after the second specified event occurs, and then the terminal device records statistical information related to the second specified event and second measurement relaxation information, where the second measurement relaxation information is used to indicate that the terminal device is not in the measurement relaxation state when the second specified event occurs.

S202, the terminal device sends the statistical information and the measurement relaxation information to the network device.

Accordingly, the network device receives the statistical information and the measurement relaxation information from the terminal device.

Alternatively, when the specified event is RRM measurement, the statistical information and the measurement relaxation information may be carried in a measurement report (MeasurementReport) message or the report information is carried in a ue information response (UEInformationResponse) message.

In one embodiment, the measurement relaxation information includes indication information 1, which is used to indicate that the terminal device is in a measurement relaxation state when a specific event occurs.

In this embodiment, the network device may determine that the terminal device is in the measurement relaxed state when a specific event occurs according to the indication information 1.

In this embodiment, the network device may determine that the terminal device is in the measurement relaxed state when the specified event occurs according to the relevant parameter for measuring the relaxed state, and obtain relevant parameter information when the terminal device is in the relaxed state, for example, the relevant parameter information includes a trigger type, a relaxed degree, and the like for measuring the relaxed state, and the network device may determine the trigger type, the relaxed degree, and the like for measuring the relaxed state when the specified event occurs in the terminal device according to the relevant parameter information. But the application is not limited thereto.

In another embodiment, the measured relaxation information includes indication information 1 and related parameter information of the measured relaxation state.

Optionally, after receiving the statistical information and the measurement relaxation information in S202, the network device may determine whether to perform network self-optimization by using the statistical information related to the specified event according to the measurement relaxation information.

Optionally, the network device may determine the reasonability of setting the measurement relaxation state and configuring the parameter according to statistical information related to a specified event recorded when the network device is in the measurement relaxation state and reported by the plurality of terminal devices.

For example, the network device receives statistical information recorded in the measurement relaxed state reported from the plurality of terminal devices, and the plurality of terminal devices have failed in the same location in the measurement relaxed state, or the network device may determine whether the measurement relaxed state should be configured for the terminal device by comparing the statistical information recorded in the measurement relaxed state of the plurality of terminal devices and the statistical information recorded in the measurement relaxed state of the plurality of terminal devices, and determine a configuration parameter value of the measurement relaxed state.

Or, the network device may perform MRO optimization on the statistical information recorded when the terminal device is in the measurement relaxation state and the statistical information recorded when the terminal device is not in the measurement relaxation state, respectively. Or, the network device may perform MRO optimization jointly with different reference weights on the statistical information recorded when the terminal device is in the measurement relaxation state and the statistical information recorded when the terminal device is not in the measurement relaxation state. But the application is not limited thereto.

Optionally, the sending, by the terminal device, the statistical information and the measurement relaxation information to the network device includes: the terminal device sends one or more reporting messages to the network device, where the reporting messages include statistical information and measurement relaxation information that are determined (or recorded or stored) by the terminal device for a specific event that occurs and are related to the specific event. Optionally, the terminal device may send the one or more pieces of reported information to the network device through a measurement report or a response message.

According to the scheme, the terminal equipment informs the network whether the network is in a measurement relaxation state or not when recording the measurement statistical information, so that the network can determine the state of the terminal equipment when recording the statistical information, reasonably refers to the statistical information provided by the terminal equipment, and the accuracy of network self-optimization is improved.

Example two

In the second embodiment, the case where the specified event is the HOF will be described. It should be noted that, for the same or similar parts in the second embodiment as in the first embodiment, reference may be made to the description of the first embodiment, and for the sake of brevity, no further description is provided herein. Fig. 3 is a schematic flowchart of an information transmission method according to the second embodiment of the present application, including but not limited to the following steps:

s301, the terminal equipment determines the occurrence of the HOF and records the statistical information related to the HOF, wherein the statistical information comprises the measurement data.

And under the condition that the HOF occurs, the terminal equipment measures to obtain measurement data and records statistical information corresponding to the HOF, wherein the statistical information comprises the measurement data.

For example, the measurement data may include RRM measurements of the serving cell and the neighbor cells

S302, the terminal device determines that the terminal device is in a measurement relaxation state in the process of obtaining measurement data, and records measurement relaxation information, wherein the measurement relaxation information is used for representing that the terminal device is in the measurement relaxation state when HOF occurs.

The terminal equipment judges whether the terminal equipment is in a measurement relaxation state in the process of acquiring the measurement data, if the terminal equipment is in the measurement relaxation state, the terminal equipment records measurement relaxation information, and the measurement relaxation information is used for indicating that the terminal equipment is in the measurement relaxation state when HOF occurs. Or, the measurement relaxation information is used to indicate that the terminal device is in a measurement relaxed state when acquiring the HOF-related measurement data.

S303, the terminal device sends the statistical information and the measurement relaxation information related to the HOF to the network device.

Accordingly, the network device receives the report information from the terminal device. Wherein, the measurement relaxation information includes the above indication information 1 and/or the related parameter information of the measurement relaxation state.

Optionally, before S303, the network device may send a UE Information Request (e.g., UE Information Request) message to the terminal device to Request the measurement statistics recorded by the terminal device. After receiving the UE Information request message, the terminal device may send a UE Information Response (e.g., UE Information Response) message to the network device, where the Response message includes the statistical Information and measurement relaxation Information related to the HOF.

When the terminal equipment is in a measurement relaxation state, the terminal equipment applies an RRM measurement relaxation mechanism, which may cause the terminal equipment to perform measurement on the neighboring cell, even the current cell is not measured in time, so that the UE cannot perform handover on the current truly optimal neighboring cell, and finally, a handover failure HOF is caused. The handover failure may not be caused by the network coverage problem, but by the untimely update reporting of the measurement result of the terminal device. If the network receives the report of the HOF and adjusts the handover parameters according to the result, it may cause the error of the optimization direction of the network. Therefore, according to the scheme provided by the second embodiment, the terminal device records the statistical information of the HOF and records the measurement relaxation information, so that after the network acquires the information recorded by the terminal device, the state of the terminal device when recording the statistical information can be determined, the statistical information provided by the terminal device is reasonably referred to, and the accuracy of network optimization is improved.

EXAMPLE III

In the third embodiment, the event is defined as CEF. It should be noted that, for the parts of the third embodiment that are the same as or similar to the parts of the first embodiment, reference may be made to the description of the first embodiment, and for the sake of brevity, detailed description is not repeated here. Fig. 4 is a schematic flowchart of an information transmission method provided in the third embodiment of the present application, including but not limited to the following steps:

s401, the terminal device determines to enter a measurement relaxation state.

For example, before S401, the terminal device receives configuration information for configuring a measurement relaxed state from the network device, where the configuration information for configuring the measurement relaxed state includes a condition for triggering the measurement relaxed state, for example, the configuration information for configuring the measurement relaxed state configures that the terminal device enters the measurement relaxed state when the terminal device is in a low mobility state, and the configuration information for configuring the measurement relaxed state includes an evaluation duration of RSRP and an RSRP threshold, and the terminal device determines that the terminal device is in the low mobility state according to a change amount of the RSRP in the evaluation duration being smaller than the threshold, thereby entering the measurement relaxed state.

For another example, the configuration information for configuring the measurement relaxation state configures the terminal device to enter the measurement relaxation state when the terminal device is located at a non-cell edge position, and the configuration information for configuring the measurement relaxation state includes an RSRP threshold and an RSRQ threshold, so that the terminal device is determined to be located at the non-cell edge position when an RSRP measurement value measured by the terminal device is smaller than the threshold and the RSRQ measurement value is smaller than the threshold, thereby entering the measurement relaxation state.

Or, the configuration information for configuring the measurement relaxation state may further configure that the terminal device enters the measurement relaxation state when the terminal device is in the low mobility state and is in a non-cell edge position, and the terminal device enters the measurement relaxation state when it is determined that the trigger condition for entering the measurement relaxation state is satisfied.

Optionally, the terminal device is in a non-connected state.

For example, the terminal device is in an IDLE (IDLE) state or an INACTIVE (INACTIVE) state.

S402, the terminal device performs RRM measurement at a first period, where the first period is greater than a second period, and the second period is a period of RRM measurement when not in the measurement relaxed state.

The terminal device performs RRM measurements with a first period while in a measurement relaxation state.

And S403, the terminal device generates CEF, and records statistical information and measurement relaxation information related to the CEF, wherein the measurement relaxation information is used for representing that the terminal device is in a measurement relaxation state when the CEF occurs.

S404, the terminal device sends the statistic information and the measurement relaxation information related to the CEF to the network device.

Accordingly, the network device receives the CEF-related statistical information and the measurement relaxation information from the terminal device. Wherein, the measurement relaxation information includes the above indication information 1 and/or the related parameter information of the measurement relaxation state.

RRM measurements made while the terminal device is in the unconnected state will be used for cell reselection decisions. If the terminal device is configured with the relevant parameters of the measurement relaxed state in the non-connected state, and the terminal device meets the condition of triggering the measurement relaxed state, after entering the measurement relaxed state, the period for the terminal device to perform RRM measurement becomes long, which may cause untimely cell reselection, so that when the terminal device needs to enter the connected state, connection cannot be established or restored, that is, CEF occurs. This failure may not be caused by network coverage problems but by the untimely RRM measurements of the terminal devices. If the network adjusts the cell system information parameters according to the obtained statistical information related to the CEF, the optimization direction of the network may be wrong.

According to the scheme provided by the third embodiment, when the UE reports the statistical information corresponding to the CEF to the network device, the UE reports the measurement relaxation information at the same time, for example, the measurement relaxation information includes the indication information 1 and/or the relevant parameter information of the measurement relaxation state. Therefore, after the network acquires the information recorded by the terminal equipment, the state of the terminal equipment when recording the statistical information can be determined, the statistical information provided by the terminal equipment is reasonably referred to, and the accuracy of network optimization is improved.

Example four

In the fourth embodiment, the RRM measurement is described as an example of the designated event. It should be noted that, for the same or similar parts in the fourth embodiment as those in the previous embodiments, reference may be made to the foregoing description, and for the sake of brevity, detailed description is omitted here. Fig. 5 is a schematic flowchart of a communication method provided in the third embodiment of the present application, including but not limited to the following steps:

s501, the terminal device determines to enter a measurement relaxation state.

The network may configure the terminal device with an SCell to increase the data transmission rate of the terminal device. If the SCell is configured with the measurement relaxed state, the terminal equipment enters the measurement relaxed state for the SCell under the condition that a triggering condition is met.

S502, the terminal device performs the RRM measurement at a first period, where the first period is greater than a second period, and the second period is a period of the RRM measurement when the terminal device is not in the measurement relaxed state.

S503, the terminal device records statistical information related to RRM measurement and measurement relaxation information, where the statistical information includes measurement data obtained by the RRM measurement.

The measurement relaxation information is used to indicate that the terminal device is in a measurement relaxation state when performing the RRM measurement. Or, the measurement relaxation information is used to characterize that the terminal device is in a measurement relaxation state when acquiring the measurement data.

S504, the terminal device sends the statistical information and the measurement relaxation information related to the RRM measurement to the network device.

Accordingly, the network device receives the RRM measurement related statistical information and the measurement relaxation information from the terminal device. Wherein, the measurement relaxation information may include the above indication information 1 and/or the related parameter information of the measurement relaxation state.

By way of example and not limitation, the RRM measurement related statistics and measurement relaxation information are carried in a measurement report (e.g., measurementReport) message.

When the terminal device performs the relaxation measurement on the RRM measurement configured for the SCell, the terminal device may fail to report the target SCell satisfying the change condition to the network in time, so that the network does not change the terminal device to a more appropriate secondary cell in time, and the data transmission rate of the terminal device is reduced. According to the scheme provided by the fourth embodiment, the terminal device may report the measurement relaxation indication information 1 when reporting the measurement data obtained by the RRM measurement. The network side stores configuration information of a measurement relaxation state, and the terminal device may only notify the network whether the network is currently in the measurement relaxation state, or further notify the network of relevant parameter information of the measurement relaxation state. Therefore, after the network acquires the information recorded by the terminal equipment, the state of the terminal equipment when recording the statistical information can be determined, the statistical information provided by the terminal equipment is reasonably referred to, and the accuracy of network self-optimization is improved.
