Description

Processing method, device, terminal and network equipment for MDT (minimization of drive test)

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for processing minimization of drive test MDT.

Background

Minimization of drive tests (Minimization of Drive Tests, MDT) measurement classification:

real-time MDT (Immediate MDT): MDT measurement and reporting are carried out by the connection state terminal. Multiplexing the radio resource management (Radio Resource Management, RRM) measurement mechanism, the terminal immediately reports to the network side once the reporting condition is met.

Record MDT (Logged MDT): and the MDT measurement performed by the idle state/inactive state terminal is reported in the subsequent connection state. Once the configured trigger conditions are met, the terminal will acquire and store (log) the measurement results, reporting to the network at a later appropriate time.

Periodic measurement in the Logged MDT configuration of the terminal depends on the cell mobility measurement result of the terminal in an idle state or an inactive state. The terminal fills a cell mobility measurement result into corresponding entries of terminal variables of the logged MDT according to a measurement period configured by the logged MDT at intervals, and each entry also contains corresponding contents such as time stamp information, geographic position information and the like.

In the case of the Logged MDT, when the terminal stores an available record, if entering a connected state or moving to a new cell, the terminal will report a record available indication (Log available) to the network through RRC signaling.

A relaxation mechanism for measurements was introduced in the Power Saving (Power Saving) stand in 5G systems. If a Power save mechanism is introduced, the terminal can relax the cell mobility measurement after meeting the conditions, i.e. lengthen the collection period of the radio resource management (Radio Resource Management, RRM) measurement results, and reduce the terminal Power consumption. For traditional logged MDT, the network configures an MDT measurement/recording period, and the result of multiple MDT measurement periods recorded by the terminal is unchanged possibly due to overlong RRM measurement time, but the MDT result collecting node cannot know whether the terminal applies a power saving relaxation mechanism, so that the network can misjudge the logged MDT measurement result reported by the terminal. In other words, the terminal power saving standpoint of power save introduces a relaxation mechanism for the measurements that affects terminal side measurement collection of the log MDT.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

As shown in fig. 1, an embodiment of the present invention provides a processing method of minimization of drive test MDT, which is applied to a terminal, and includes:

step 11, recording a measurement result according to a first measurement interval of a logged MDT (the logged MDT); the first measurement interval is greater than or equal to a second measurement interval configured by a network for the logged MDT; wherein the measurement result comprises a plurality of record entries;

The embodiment of the invention provides at least two MDT processing methods, which are respectively as follows:

the first treatment method comprises the following steps: the terminal records the measurement results at a measurement interval configured by the network (i.e., the first measurement interval is equal to the second measurement interval). Carrying a first identifier for a recorded entry which is recorded and not updated by the measurement result, and/or carrying a second identifier for a recorded entry which is not obtained by the measurement; the method can save the record of MDT measurement results and the size of the reported data volume.

The second treatment method comprises the following steps: the terminal records a measurement result according to a first measurement interval which is larger than a second measurement interval configured by the network; which can make the measurement result closer to the actual measurement situation of the terminal. For the second processing manner, that is, when the first measurement interval is greater than the second measurement interval, at least one record entry in the plurality of record entries includes a first identifier and/or at least one record entry includes a second identifier, which can further save the size of the data volume recorded and reported by the MDT measurement result.

Further, the method further comprises:

and reporting the recorded measurement result to a network.

Note that, for the record entry including the first identifier, the RRM measurement configuration may be a measurement result that the record entry is not updated with respect to the MDT measurement interval, or may be a measurement result that a relaxation mechanism is applied to cause the record entry to not be updated, which is not specifically limited herein.

As an alternative embodiment, the record entry includes at least one of:

a service cell identification of the terminal;

measurement information of a serving cell of the terminal;

measurement information of neighbor cells of the terminal;

geographic location information of the terminal.

Wherein the measurement information includes at least one of:

cell-level signal strength;

cell-level signal quality;

beam level signal strength;

beam level signal quality.

For example, cell-level signal strength of the serving cell, cell-level signal quality of the serving cell, beam-level signal strength of the serving cell, beam-level signal quality of the serving cell; cell-level signal strength of a neighboring cell, cell-level signal quality of the neighboring cell, beam-level signal strength of the neighboring cell, beam-level signal quality of the neighboring cell.

Example one

As shown in fig. 2, the terminal records the measurement result according to the measurement interval configured by the network, and carries the first identifier for the record entry which has been recorded but not updated by the measurement result.

The record entry that may include the "first identifier" may include one or more of the following:

a service cell identification;

serving cell measurement information, such as cell-level signal strength, and/or cell-level signal quality, and/or beam-level signal strength, and/or beam-level signal quality;

each neighbor cell measurement information, such as cell-level signal strength, and/or cell-level signal quality, and/or beam-level signal strength, and/or beam-level signal quality;

geographic location information.

If the network setup does not perform a relaxation mechanism for high priority frequency points (only for equal priority or low priority frequency points), it may be different if the signals of neighbor cells for different frequency points change under the configuration of the measurement interval of the fixed MDT. The terminal records the first identifier by aiming at the signal record of the adjacent cell and can record the first identifier by frequency points with different priorities.

In order to distinguish from the "measurement result (i.e., first identification) that has been recorded but not updated in the next period", it is also possible to add a related "no neighbor measurement result (i.e., second identification)" indication for a scene where the terminal actually performs neighbor measurement but no measurement result is obtained in at least one record entry. Based on the second identifier, when the base station parses a certain record entry, it can be clearly known whether the current record entry has no reported neighbor measurement, which is caused by a problem of network configuration or terminal implementation (due to the fact that a relaxation mechanism is executed or no neighbor measurement is executed in a measurement period corresponding to the current entry because the recorded MDT and the RRM configuration period are not matched), or due to coverage holes (the terminal executes the neighbor measurement but does not obtain the neighbor measurement result).

By the above example, the size of the data volume of the record/report of the measurement result of the record-type MDT can be greatly saved, and unnecessary repeated information report is avoided.

As another alternative embodiment, for the second processing method, in a case where the first measurement interval is greater than a second measurement interval configured by the network for the logged MDT, the method further includes:

or,

The second treatment method may also be referred to as: based on the measurement interval configured by the network, the terminal ignores the recording time point of the measurement result, stretches the measurement interval to execute measurement recording, and the relative interval time can be recorded in a relative time stamp.

Further, in the case that the first coefficient is determined by the terminal, the method further includes:

Regarding the "energy saving threshold", the terminal may be obtained from system information of the network device, and the first coefficient corresponding to the reached energy saving threshold may be pre-agreed or pre-configured.

For example, a relaxation mechanism may be performed (the network may set whether to perform the relaxation operation for high priority frequency points) when the terminal meets the following threshold:

if the terminal is in a low mobility state according to the signal value difference values of the terminal at different moments; or if the terminal is judged not to be at the cell edge according to the signal strength and the signal quality value of the terminal.

For example, if the terminal reaches the energy saving threshold 1, the corresponding first coefficient is a; for another example, if the terminal reaches the energy-saving threshold 2, the corresponding first coefficient is B; for another example, if the terminal reaches the energy saving threshold 1 and the energy saving threshold 2, the corresponding first coefficient is C.

The specific measurement interval information configured by the network for the relaxation mechanism of the terminal can be one specific measurement interval information or a plurality of specific measurement interval information; if the measurement interval information is a plurality of specific measurement interval information, determining the first measurement interval according to the specific measurement interval information configured by the network for a relaxation mechanism of the terminal, wherein the first measurement interval comprises;

For example, if the terminal reaches the energy saving threshold 1, the corresponding specific measurement interval information is interval 1; for another example, if the terminal reaches the energy-saving threshold 2, the corresponding specific measurement interval information is interval 2; for another example, if the terminal reaches the energy saving threshold 1 and the energy saving threshold 2, the corresponding specific measurement interval information is interval 3.

As another alternative embodiment, in the case that the first measurement interval is greater than a second measurement interval configured by the network for the logged MDT, the method further includes:

In other words, the terminal does not rely on the first coefficient or the specific measurement interval information, and the measurement result is recorded when the terminal RRC layer acquires a new RRM measurement result. The measurement results are not recorded for time nodes that do not acquire new RRM measurement results but meet the measurement interval of the network configuration.

Example two

The terminal lengthens the second measurement interval to perform recording of the measurement result. The terminal stretches the second measurement interval according to the first coefficient, or determines the first measurement interval according to specific measurement interval information aiming at a relaxation mechanism, and the relative interval time is recorded in a relative timestamp to be embodied. The first coefficient or specific measurement interval information may be determined by:

The terminal stretches a first measurement interval according to a first coefficient of network configuration; or setting specific measurement interval information separately for the relaxation mechanism;

the terminal acquires the energy-saving related threshold of the terminal in the system information, judges whether the threshold of a relaxation mechanism in the energy saving of the terminal is reached, and then sets specific measurement interval information independently according to a fixed coefficient (for example, 2 times/3 times/4 times of time length) when each threshold is met or aiming at the relaxation mechanism, which is determined in advance.

For example, the terminal may reach a threshold for the release mechanism in terminal power saving, either one threshold (terminal in cell center, or terminal in low mobility) or two thresholds (both terminal in cell center and terminal in low mobility) are met. The first coefficient used by the terminal or the specific measurement interval information may be different for terminals reaching different thresholds. For example, when the terminal reaches a single threshold of 1, the first coefficient=2; when the terminal reaches a single threshold of 2, the first coefficient=4; when the terminal reaches both thresholds at the same time, the first coefficient=10 or the measurement interval of MDT is set separately=1 hour.

As shown in fig. 3, the recording interval of the MDT is lengthened by the network configuration or by the first coefficient=3 calculated by the terminal itself, i.e., the length of time of the terminal by 3 times the first measurement interval of the current MDT configuration.

If the network setup does not perform this relaxation mechanism for high priority frequency points (only for equal priority or low priority frequency points), the recording interval of the actually used MDT may also be different for neighboring cells of different frequency points. The measurement result records of the terminal at different moments may include only the identification of partial frequency points, the identification of neighboring cells under the corresponding frequency points and the measurement result, except the identification/measurement result, the geographical position information and the time stamp of the own cell of the terminal.

By the method, the terminal can feed back the logged MDT measurement result which is closer to the actual measurement condition of the terminal to the network side according to the configuration parameters of the network side or according to other schemes (such as a power save relaxation measurement mechanism) configured by the network side, and the logged MDT records/reports the data size.

Example three

The terminal does not rely on the first coefficient or specific measurement interval information, the adaptive lengthening measurement interval, and the relative interval time is recorded in the relative time stamp for representing.

As shown in fig. 4, the periodic measurement result recorded by the original terminal is recorded according to the first measurement interval configured by the network. If there is no new measurement result at the end of the first measurement interval configured by the MDT due to power saving of the terminal or the like, the terminal may directly skip the measurement result record at the time point, and may not record in the next nearest measurement result until there is a new measurement result acquired at the RRC layer of the terminal.

By the method, the terminal can inform the network side of the measurement result of the logged MDT which is closer to the actual measurement condition of the terminal, and the data size of the logged MDT record/report is saved.

In summary, in the embodiment of the present invention, a terminal records, for a logged MDT, a measurement result according to a first measurement interval, where the first measurement interval is greater than or equal to a second measurement interval configured by a network for the logged MDT, and in a case where the first measurement interval is equal to the second measurement interval, at least one of the plurality of logged entries includes a first identifier and/or at least one logged entry includes a second identifier, where the first identifier is used to indicate that a current measurement result of a corresponding logged entry is the same as a previous measurement result; the second identifier is used for indicating that the terminal does not obtain a measurement result of the corresponding record item in the current measurement; according to the embodiment of the invention, the measurement result recorded by the measurement interval is closer to the actual measurement condition of the terminal, and the MDT record of the terminal and the reported data size are saved.
