Description

Cell measurement method, device and storage medium

Technical Field

The present application relates to communications technologies, and in particular, to a cell measurement method, device, and storage medium.

Background

In order to ensure a connection between a network and a User Equipment (UE), mobility management, which is a generic term for related procedures, is not interrupted by the movement of the UE. The mobility management can be roughly divided into an IDLE state (RRC _ IDLE state) mobility management and a CONNECTED state (RRC _ CONNECTED state) mobility management according to the current state of the UE. In the idle state, the mobility management mainly refers to a cell selection/reselection (cell selection/reselection) process, and in the connected state, the mobility management mainly refers to a cell handover (handover). Whether cell selection/reselection or handover is based on the results of the measurements.

For the 2G, 3G and 4G modes, the signal for measurement is always present. In the 5G mode, however, the signal for measurement is not always present but is present periodically. The configuration of the measurement signal in the 5G mode is referred to as measurement timing configuration (SMTC). At present, how to measure a 5G network is not described in particular, if each frequency point measures in a fixed time period according to the scheduling strategy of measuring a 2G/3G cell by using the existing 4G, when measuring 5G, since the whole continuous time period is divided into 5G mode measurement, the time which is not in the measurement time window is wasted.

At present, if the measurement mode of the 3G and 4G cells is directly applied to the measurement process of the cells including the different frequency or different system of the 5G cell, the problems of long measurement time, high power consumption of the UE and the like are easily caused.

In the scheme, several ways of obtaining the measurement timing configuration are provided, and the UE may obtain the measurement timing configuration configured by the network side for the first cell through the system information of the network side, or may be written in the protocol in advance, and the UE may read the measurement timing configuration when it needs to be used, or may select the measurement timing configuration obtained by the UE itself for the purpose of optimizing the scheme.

In the specific process of cell measurement in this scheme, if the UE is in a connected state scene, in the measurement period, the frequency point to be measured of the first cell is measured in the measurement time window of the frequency point to be measured of the first cell, and the frequency point to be measured of the second cell is measured at a time other than the measurement time window of the frequency point to be measured of the first cell, including:

Detailed Description

As can be seen from the background, there is no specific description in the prior art on how to perform the measurement of the 5G cell, if according to the scheduling policy of the existing 4G measurement, 2G or 3G cell: each frequency point is measured in a fixed time period, and when 5G is measured, the whole continuous time period is divided into 5G mode measurement, so that the time which is not in the measurement time window is wasted. In view of the above problem, the present application provides a cell measurement method, which can measure a cell including a pilot frequency or a pilot system of a 5G cell, reduce measurement time, and reduce power consumption of a terminal, and the following describes the scheme with specific embodiments.

The network element involved in the method for measuring the cell provided by the body comprises network equipment and a terminal of a user, namely user equipment. The network device refers to a device with radio resource management function, which can communicate with the user equipment or act as a central controller to assist the user equipment in direct communication, for example: and a base station.

Fig. 2 is a schematic diagram of a specific application scenario of the cell measurement method provided in the present application, as shown in fig. 1, the scenario relates to a UE and a base station, that is, a network device is a base station, and the following takes the scenario as an example to describe the cell measurement method provided in the present application.

In a specific implementation of the scheme, the base station knows whether the UE supports inter-frequency inter-system measurement by querying the UE capability. For UE supporting inter-frequency inter-system measurement, a base station can issue a system message (in an idle state) or a measurement request message (for example: a reconfiguration message) (in a connected state), the message issues thresholds A1 and A2, when a signal condition meets an A2 event, the UE starts the inter-frequency inter-system measurement and reports the measurement according to the requirement in the message, and when the base station judges that the signal condition meets the inter-frequency inter-system switching or redirection threshold, the base station issues a switching indication message or redirection message and starts a related process; and when the signal condition meets the A1 event, the UE stops the inter-frequency inter-system measurement.

In the connected state, when the inter-frequency or inter-system measurement is triggered, the base station issues the relevant configuration of the measurement GAP. The measurement GAP is a time period from the UE leaving the current frequency point to the measurement of other frequency points. Measuring GAP can be divided into a mode 1 and a mode 2, wherein the GAP in the mode 1 is 6ms, and the period is 40ms; GAP in mode 2 is 6ms, and the period is 80ms. When the pilot frequency is measured, the UE needs to leave the current frequency point and measure to other frequency points, so that the service of the UE cannot be normally performed in the GAP period, which results in a decrease in the mobile data rate of the UE.

Some concepts presented in this solution are introduced below, in particular as follows:

the serving cell refers to a cell in which the UE currently resides or a cell in which data transmission is being provided for the UE.

The neighbor cell refers to a cell near a service, may also be a neighbor cell, may be the same base station, or may not be the same base station. As a spare cell.

The same-frequency cell is a cell with the same frequency as the serving cell and also has a same-frequency adjacent cell.

The pilot cell is a cell having a frequency different from that of the serving cell.

The cells of the different systems are cells with different systems (or modes) from the serving cell, that is, cells using different radio access technologies. The standards herein refer to 2G, 3G, 4G, and 5G. Say 2G and 4G cells under a mobile operator.

Under the measurement scene containing the timing configuration frequency point and the non-timing configuration frequency point, the scheme provides a method for the terminal to preferentially measure the cell in the time window according to the timing configuration of the measurement.

The terminal may be in 2G, 3G, 4G, 5G mode, and measurements are made on cells having measurement timing configurations like the 5G mode. The method specifically comprises the following scenes:

1) In a connection state of a terminal device, a terminal is configured to continuously receive a scene (namely a non-DRX scene), if a measurement time window (namely measurement opportunity) of measurement timing configuration falls in a Gap, the Gap preferentially schedules a measurement timing configuration frequency point; otherwise, scheduling the pilot frequency/inter-system frequency point without measurement timing configuration.

2) In the connected state of the terminal device, the terminal is configured to receive Discontinuous Reception (DRX) in the active period scenario, the process is the same as above.

3) In a connected state of a terminal device, under an inactive period scenario in which the terminal is configured as DRX, a measurement time window (measurement opportunity) of measurement timing configuration is reserved preferentially in the inactive period for measuring a cell of the measurement timing configuration, and the remaining inactive period time is used for scheduling an inter-frequency/inter-system without the measurement timing configuration.

4) In the idle state (i.e., idle state) of the terminal device, the terminal is configured to be in the inactive period scenario, as in 3).

The technical scheme of the application is not only suitable for measuring the cell scene under another 5G system by the cell under the 2G, 3G and 4G systems; the method is also used for the scenes of inter-frequency cell measurement in a 5G mode and inter-system cell measurement in 2G, 3G and 4G modes; the method is also suitable for measurement scenes of timing configuration cells and non-timing configuration cells under all systems (2G, 3G, 4G and 5G); the method is also suitable for measuring the timing configuration cell of a new standard in the future and the current non-customized configuration cell, and the method is not limited.

On the basis of the above scenario, the following is a method for measuring a cell provided by the present application through several specific embodiments.

Fig. 3 is a flowchart of a first embodiment of a cell measurement method provided in the present application. As shown in fig. 3, this embodiment takes two cells as an example, namely a first cell and a second cell, where the first cell needs to perform measurement timing configuration; the second cell is a cell which needs to be configured with measurement timing, that is, a cell without measurement timing configuration. The first cell and the second cell are different system cells or different frequency cells, and the different systems refer to that the first cell and the second cell adopt different wireless access technologies, namely different types of networks; the pilot frequency means that the first cell and the second cell are different frequency points in the same access technology. Accordingly, the method for measuring a cell provided in this embodiment specifically includes the following steps:

s101: and determining a measurement time window of the frequency point to be measured in the measurement period according to the measurement timing configuration corresponding to the first cell acquired in advance.

In this step, a mode in which a 5G or other measurement signal does not exist all the time but exists periodically may be referred to as an SSB Measurement Timing Configuration (SMTC). The SMTC includes a period, a length, and an offset of a measurement time window of the SMTC. The UE only needs to make the measurement of the SSB within this time window. The SSB period has various configurations from 5ms to 160 ms. For the same-frequency measurement, the network side may be configured with at most two SMTCs, the two SMTCs use the same length and time offset, and the periods may be different. For pilot frequency measurement, the network side only configures one SMTC for each frequency point. When measuring cells of 5G and non-5G mode (2G, 3G, 4G), 5G cells need to be measured within a certain measurement time window due to the periodicity of the 5G cell signals; if the 5G cell is measured outside the time window, the 5G cell is not measured, wasting measurement time.

Accordingly, when performing inter-frequency or inter-system cell measurement in this solution, the UE first needs to obtain a measurement timing configuration of the first cell requiring measurement timing, where the measurement timing configuration includes a measurement period, an offset position, and a duration, and these parameters are the period, the offset, and the length of the measurement time window.

The method for the UE to obtain the measurement timing configuration of the first cell at least includes the following steps:

in a first manner, the UE receives system information sent by the network device, where the system information carries the measurement timing configuration corresponding to the first cell.

The meaning of the scheme is that a network side configures measurement timing of a first cell through system information or other high-level signaling, specifically, a message carrying the measurement timing configuration may be a system message, or a reconfiguration message, and the scheme is not limited.

A second mode, acquiring the measurement timing configuration corresponding to the first cell specified in a protocol;

the meaning of the scheme is that the measurement timing configuration corresponding to the first cell is specified in the protocol, that is, written in the protocol, and the UE only needs to read the measurement timing configuration from the protocol in the using process.

In a third mode, the measurement timing configuration is selected according to a preset rule.

In the scheme, the UE selects a proper measurement period, an offset position and a duration time for optimizing the scheme to obtain the measurement timing configuration, and then performs cell measurement according to the measurement timing configuration.

After obtaining the measurement timing configuration for the first cell, the UE needs to obtain a measurement time window, also called a measurement opportunity, for measuring the frequency point to be measured of the first cell. That is, the UE needs to calculate a measurement time window (i.e., a measurement opportunity) of the frequency point to be measured of the first cell in the measurement period of this round according to the measurement period and the offset position in the measurement timing configuration.

S102: in the measurement period, the frequency point to be measured of the first cell is measured in the measurement time window of the frequency point to be measured of the first cell, and the frequency point to be measured of the second cell is measured at a time except the measurement time window of the frequency point to be measured of the first cell.

S103: and reporting the measurement result of the first cell and the measurement result of the second cell to the network equipment.

When the inter-frequency or inter-system measurement is triggered, the network side issues the relevant configuration of the measurement GAP (GAP). The measurement GAP is a time period from the UE leaving the current frequency point to the measurement of other frequency points. Measuring GAP (GAP measurement) into a mode 1 and a mode 2, wherein the GAP in the mode 1 is 6ms, and the period is 40ms; GAP in mode 2 is 6ms, and the period is 80ms. When the pilot frequency is measured, the UE needs to leave the current frequency point and measure to other frequency points, so that the service of the UE cannot be normally performed in the GAP period, which results in a decrease in the mobile data rate of the UE.

In the above steps, the UE obtains a measurement time window of a measurement frequency point of a first cell, after entering a measurement period, if the measurement time window of a certain frequency point to be measured of the first cell falls within a GAP, the GAP is used to measure the frequency point to be measured of the first cell, and after the measurement of the frequency point to be measured is completed, the UE may report a measurement result to the network device.

If the measurement time window of the frequency point to be measured of the first cell does not fall within the GAP, the inter-frequency/inter-system of the cell without measurement timing can be measured, for example, in the scheme, the frequency point to be measured of the second cell can be measured, and then the corresponding measurement result is reported to the network device.

In this solution, it should be understood that, assuming that multiple frequency points need to be measured for measurement of the first cell, the UE may report the measurement result to the network device after measuring one frequency point to be measured each time, or report the total measurement result of the first cell to the network device after completing measurement of all frequency points to be measured of the first cell, which is not limited in this solution. For the frequency point measurement of the second cell, the same reasoning applies, and the UE may report the measurement result to the network device after measuring one frequency point to be measured each time, or report the total measurement result of the second cell to the network device after measuring all the frequency points to be measured of the second cell.

When the UE specifically performs cell measurement, the UE may perform measurement reporting on the serving cell and the neighboring cell, or may shorten the measurement time according to the measurement method, and report measurement results of different cells after completing the measurement of the serving cell and the neighboring cell.

Optionally, in a specific implementation of the scheme, after the UE completes measurement on the frequency point to be measured in the first cell and reports the measurement result to the network device, the frequency point to be measured is marked as a measured frequency point.

Or after the frequency point to be measured of the second cell is measured and the measurement result is reported to the network equipment, the frequency point to be measured is marked as the measured frequency point.

After reporting the measurement result of the frequency point which has finished measurement, the UE may mark the measured frequency point as a measured frequency point.

In the cell measurement method provided in this embodiment, the UE preferentially measures the cell in the time window according to the obtained measurement timing configuration of the cell requiring measurement timing, so that the cell requiring measurement timing configuration can be reported quickly, the cell requiring measurement timing is measured at a time outside the time window, the measurement time is not wasted, the measurement efficiency of the cell is improved, and the cell reselection and handover performance is improved.

On the basis of the above embodiment, in a specific application process of the scheme, the UE is in different scenarios, the specific measurement modes are different, the UE states include a connected state and an idle state, the UE also includes a scenario in which the DRX characteristic is configured and a scenario in which the DRX is not configured in the connected state, and the UE also includes an active period and an inactive period in the scenario in which the DRX characteristic is configured in the connected state; the UE includes an active period and an inactive period scenario in an idle state.

The specific implementation of step S102 of the UE in different scenarios of the connected state and the idle state is slightly different, and the following describes the UE through two specific examples.

When the UE is in a connected state and does not configure the DRX scenario or configures a scenario of the DRX scenario in an active period, the step S102 is specifically implemented as:

The meaning of the scheme is that in a measurement period, if a measurement time window of a frequency point to be measured of a first cell falls in a measurement GAP (GAP), the measurement GAP is used for measuring the frequency point to be measured of the first cell, otherwise, the measurement GAP is used for measuring the frequency point to be measured of a second cell. And respectively measuring the frequency point to be measured of the first cell and the frequency point to be measured of the second cell according to the mode to obtain respective measurement results, and reporting the measurement results.

If the measurement opportunity of the frequency point to be measured of the first cell falls in the Gap, the Gap preferentially schedules and measures the frequency point to be measured configured at the measurement timing; otherwise, scheduling the measurement of the different frequency/different system without measurement timing configuration, which comprises the following steps:

1) At a certain scheduling point (for example, 10ms ahead of the Gap position), the UE calculates a measurement time window (measurement timing) of the frequency point to be measured of the first cell in the measurement period of this round according to the measurement period and the offset position in the measurement timing configuration of the first cell, and if the measurement timing of the frequency point to be measured of the first cell falls within the Gap, the Gap is used for measuring the frequency point to be measured.

2) And if the measurement opportunity of the frequency point to be measured of the first cell does not fall in the Gap, scheduling the measurement of the cell of the pilot frequency/pilot system without measurement timing configuration, and in the scheme, scheduling the frequency point of the second cell for measurement.

3) After the frequency point to be measured is measured, the measurement result is reported to the network equipment, and the frequency point can be set as the measured frequency point.

Based on the above scheme, a specific implementation of the embodiment shown in fig. 3 is described below by taking a specific example as an example.

Fig. 4 is a schematic diagram of frequency point measurement according to an example of a cell measurement method provided by the present application, and as shown in fig. 4, taking an example that a DRX scene is not configured when a UE is in a connected state, in the scheme, a GAP period is a schedule of 40ms, and a square in a time sequence in the diagram respectively represents different GAP periods that can measure frequency points to be measured of different cells, where in each GAP period of 40ms, a GAP duration is 6ms, and a time at which the frequency points of a cell can be measured in a GAP period falls within the GAP. The figure shows a measurement schematic of three different cells. In the measurement timing configuration of the cell 1, the measurement period is 160ms, that is, four GAP periods are included, the cell 1 needs 3 measurements to be completed, and the measurement of the cell 1 in the GAP period is represented by 1 in the block in the figure; in the measurement timing configuration of the cell 2, the measurement period is 80ms, that is, two GAP periods are included, the cell 2 needs 6 measurements to be measured, and 2 is used in a block in the figure to measure the cell 2 in the GAP period; cell 3 is a cell without measurement timing configuration, and needs to perform measurement for 12 times, and the measurement performed on cell 3 in the GAP period is represented by 3 in the block in the figure. Of these several cells, the first cell involved in the foregoing scheme may be cell 1 or cell 2 in this example, and the second cell may be cell 3.

According to the measurement scheme of the cell provided in the above embodiment, after the measurement timing configurations of the cell 1 and the cell 2 are obtained, at a certain scheduling point, the UE determines the measurement time window of the cell 1 and the measurement time window of the cell 2 according to the respective measurement timing configurations, and determines whether the measurement time window of the cell 1 or the cell 2 falls within a GAP in the GAP period when the first GAP period (i.e., #0 in the figure) is performed, and as shown in fig. 4, the measurement time windows of the cell 1 and the cell 2 do not fall within the GAP in the GAP period, and the GAP is used to measure the frequency to be measured of the cell 3, and so on, in the next GAP period, which cell to perform measurement is also determined according to the method.

According to the scheme, the frequency points to be measured of the cell 1 and the cell 2 which are configured at regular time are preferentially measured, taking the cell 1 as an example, the time required for the 3 frequency points to finish the measurement and report is as follows: (3 +6+ 12) = 40=840ms, where cell 1 needs three GAP periods to be measured, cell 2 needs six GAP periods to be measured, and cell 3 needs twelve GAP periods to be measured, and the total is twenty-one GAP period, that is, 840ms.

Compared with the original scheme of measuring the cells of the 4G network, the time period for measuring each cell for measuring 12 GAPs is 3 × 12 × 40=1440ms after the measurement of the three cells and the report completion time of the three cells is shortened by 1440-840=600 (ms).

The UE is in a connected inactive period scenario configured with DRX or an idle inactive period scenario (which may be collectively referred to as an inactive period scenario), where step S102 is specifically implemented as:

In a specific implementation manner, in a measurement period, at a certain scheduling point, the UE selects a measurement time window of a frequency point to be measured of a first cell closest to a current time, reserves the time of the measurement time window for measuring the frequency point to be measured of the first cell, and measures the frequency point to be measured of a second cell at a time of an inactive period before the measurement time window. And then reporting the respective measurement results obtained by measurement.

The method includes the steps that after a measurement time window of a frequency point to be measured of a first cell is determined, UE selects a measurement time window closest to the current time according to the measurement time window, the frequency point to be measured of the first cell is reserved and measured, the frequency point to be measured of a second cell is measured in the time before the measurement time window, after the measurement of the frequency point to be measured in the measurement time window is completed, the next measurement time window for measuring the frequency point to be measured of the first cell is reserved continuously, the frequency point to be measured of the second cell is measured in the time before the measurement time window, and the steps are repeated until the measurement of the first cell and the measurement of the second cell are completed.

In a non-active period scenario or an Idle state non-active period scenario in which DRX is configured in a connected state, the UE preferentially reserves a measurement time window (measurement time) of measurement timing configuration (that is, the frequency point to be measured of the first cell) for measuring the measurement of the cell configured at the timing, and the remaining non-active period time is used for scheduling the measurement of the cell of the different frequency/different system without the measurement timing configuration. The method comprises the following specific steps:

1) At a certain scheduling point (for example, the first slot (slot) entering the active period), the UE calculates a measurement time window (measurement opportunity) of the frequency point to be measured in the measurement period of the current round according to the measurement period and the offset position in the measurement timing configuration.

2) A nearest measurement time window is selected, and the time window is reserved for measuring the frequency point to be measured of the cell with the timing configuration (i.e. the first cell in the foregoing scheme), and the time of the inactive period in front of the measurement time window can be used for scheduling the measurement of the cell of the inter-frequency/inter-system without the timing configuration (i.e. the measurement of the second cell can be scheduled).

3) And after the frequency point to be measured is measured, reporting the measurement result to the network equipment. The frequency point may be set to the measured frequency point. And when the frequency point measurement is completed, as a new scheduling point, repeating the

steps

1 and 2 until the measurement of each cell is completed.

Fig. 5 is a schematic diagram of frequency point measurement according to another example of the cell measurement method provided in the present application, and as shown in fig. 5, a scheduling example in which the UE is in an idle DRX scene and a DRX cycle is 640ms is used.

In fig. 5, P denotes the timing of paging for receiving paging, and the following inactive period time is used for measurement. If the first iso-frequency/iso-system frequency point is the frequency point of a cell (i.e. the aforementioned second cell) which is not configured in a timing manner, the measurement time needs 90ms. The frequency point of the cell of the second iso-frequency/iso-system (i.e. the aforementioned first cell) is a timing configuration frequency point, and when the measurement period indicated in the measurement timing configuration is 80ms, the offset is 20ms, and it takes 3 measurements to complete the measurement, and the cell is indicated by 2 in the block in the figure.

After the UE finishes paging, it starts measurement, and preferentially reserves a measurement time window (20-30, 100-110, 180-190) (i.e. a position indicated by 2 on the time axis in the figure) for measuring the cell configured with timing. The remaining time is used for measuring the first frequency point, and the measuring time duration of the two frequency points is 190ms, which saves (250-190 = 60) 60ms compared with the previously adopted 4G technical scheme. Therefore, the power consumption is reduced by 60ms of wake-up current, and the reporting time is advanced by 60ms.

In the prior art, a fixed measurement time period is allocated to each frequency point, and if a cell (for example, a 5G cell) configured at a fixed time exists in the time period, when a measurement opportunity (for example, a GAP) is measured, since a signal transmitted by a base station does not exist, the cell cannot be measured, and thus measurement time is wasted.

In the above scheme provided by the present application, the UE preferentially measures the cell in the time window according to the measurement timing configuration, so that the cell configured at the measurement timing can be reported quickly, the measurement is accelerated, the measurement time is not wasted, and the reselection and handover performance is improved. In an actual product, due to the fact that discontinuous reception exists, measurement time is effectively shortened, therefore, the awakening time and the radio frequency working time of the terminal are shortened, and power consumption of the terminal is reduced.
