Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It should be noted that, in the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

First, the related technical content of the embodiment of the invention is introduced:

when the 3G is evolved to the 4G, the evolution is called as the integral evolution, namely the integral packaging of the radio access network and the core network is evolved from the 3G to the 4G.

However, when 4G evolves to 5G, the radio access network and the core network are split, and the 5G radio access Network (NR), the 5G core network, the 4G core network, and the 4G radio access network (LTE) are mixed and collocated to form an evolution route of 8 network deployment options, where networking options related to 5G in the 8 network deployment options mainly include option 2, option 3, option 4, option 5, and option 7 shown in fig. 1 below.

Accordingly, fig. 2 is a schematic diagram of a specific deployment scenario of several networking options corresponding to the several networking options shown in fig. 1.

Option 2: an independent networking (SA) mode, wherein a 5G core network is introduced, and only a 5G base station is connected with the 5G core network;

option 3: a non-independent Networking (NSA) mode, wherein a 4G core network is connected, a 4G base station is a main station, and a 5G base station is an auxiliary station;

option 4: a non-independent Networking (NSA) mode, wherein a 5G core network is introduced, a 5G base station is a main station, and a 4G base station is an auxiliary station;

option 5: an independent networking (SA) mode, in which a 5G core network is introduced, but only 4G base stations are connected to the 5G core network;

option 7: the non-independent Networking (NSA) mode is characterized in that a 5G core network is introduced, a 4G base station is a main station, and a 5G base station is an auxiliary station.

As can be seen from the above table, the so-called non-independent networking is dual connectivity of LTE and NR new radios, and because of differences in specific implementations, three architectures are included: EN-DC (option 3), NE-DC (option 4), and NGEN-DC (option 7) architectures.

Wherein DC represents Dual Connectivity, i.e. Dual Connectivity; e represents a 4G radio access network (E-UTRA); n represents 5G New Radio (NR); NG stands for next generation core network, i.e. 5G core network.

EN-DC refers to the dual connection of 4G radio access network and 5G NR, NE-DC refers to the dual connection of 5G NR and 4G radio access network, and NG-DC refers to the dual connection of 5G NR and 4G radio access network under 5G core network.

According to the specification of the 3GPP protocol, the network device needs to configure the measurement duration under EN-DC, also referred to as measurement interval and measurement Gap, which may be denoted as Gap or Gap, and the terminal device performs measurement on the 5GNR cell according to the configuration information, and once the 5G information is detected, reports the measurement result to the network device.

In the related art, the terminal device measures the NR cell according to the configuration derived from the network device.

Relevant provisions for measurements are included in 3GPP protocol a 37.340:

in EN-DC, NGEN-DC, and NE-DC, for a UE configured with inter-frequency measurement of E-UTRA, as shown in Table 9.1.2-2 in TS 38.133[8], a measurement gap configuration is always provided.

The relevant provisions for measurements in the above-mentioned 3GPP protocol a 37.340. The corresponding specific protocol content is as follows:

A 3GPP 37.340

7.2Measurements

A measurement gap configuration is always provided:

-In EN-DC,NGEN-DC and NE-DC,for UEs configured with E-UTRA inter-frequency measurements as described in table 9.1.2-2in TS 38.133[8].

further, 5.5.2.9 in 3GPP protocol B3GPP 38.331 includes relevant provisions regarding measurement gap configuration:

the UE shall:

1> if the measurement interval configuration is set to set:

2> if EN-DC is configured:

3> if the FR1 gap is set to true:

4> applying gap configuration for LTE serving cell and NR serving cell on FR 1;

for the other cases of 3 >:

corresponding to the above 4>, adopting gap configuration for LTE and NR service cells;

corresponding to the above 3>, if the measurement gap advance (meas gap time advance) is set to true, a timing advance value of 0.5ms is applied to the gap calculated above according to TS 38.133[16 ];

remarks 1: the UE applies a single gap, which is related to the Master Cell Group (MCG) element, even if DC is configured. In the case of EN-DC, the UE can be configured as a single (common) gap or two separate gaps, i.e., the first gap for FR1 and the second gap for FR2 (configured by NR RRC).

The above FR1 is a Frequency band in the NR system, and two Frequency bands are mainly considered in the NR system at present, a Frequency band FR1 (Frequency range 1) and a Frequency band FR2 (Frequency range 2), where Frequency domain ranges included in FR1 and FR2 are shown in table 1. It should be understood that the embodiments of the present application may be applied to the FR1 and FR2 frequency bands, and may also be applied to other frequency bands, for example, the frequency band from 52.6GHz to 71GHz, or the frequency band from 71GHz to 100GHz, and the like, which is not limited in the present application.

TABLE 1

5.5.2.9 in the above 3GPP protocol B3GPP 38.331 includes relevant provisions related to measurement gap configuration, and the corresponding specific protocol contents are as follows:

B 3GPP38.331

5.5.2.9Measurement gap configuration

The UE shall:

1>if measGapConfig is set to setup:

2>if EN-DC is configured:

3>if fr1-Gap is set to TRUE:

4>apply the gap configuration for LTE serving cells and for NR serving cells on FR1；

3>else:

4>apply the gap configuration for LTE and NR serving cells；

3>if mgta is set to TRUE,apply a timing advance value of 0.5ms to the gap occurrences calculated above according to TS 38.133[16]；

NOTE 1:The UE applies a single gap,which timing is relative to the MCG cells,even when configured with DC.In case of EN-DC,the UE may either be configured with a single(common)gap or with two separate gaps i.e.a first one for FR1 and a second one for FR2(that is configured by NR RRC).

in an actual communication process, in some cases, a gap or an SMTC window is not configured for a network device, or a position deviation between the gap or the SMTC window configured for the network device and an actually existing NR SSB is large, so that NR cell measurement is performed depending on network device configuration, which may cause a problem that a terminal device may not perform NR cell measurement or may not flexibly perform NR cell measurement.

From the perspective of the terminal device, on the one hand, in the above situation, since the network device does not configure the gap and SMTC windows, or the configuration of the gap or SMTC is inaccurate, the terminal device may not normally measure the 5G cell, so that the 5G network cannot be used.

On the other hand, in the above situation, since the current service condition of the terminal device is not considered in the network device configuration, the measurement interval configuration cannot be flexibly performed for the terminal device, so that the terminal device cannot flexibly implement NR cell measurement.

In order to solve the above problem, in the NR cell measurement method provided in the embodiment of the present invention, a terminal device determines a first measurement duration measured by a NR cell according to a current service condition in a serving cell, where the serving cell is an LTE cell in an EN-DC system; and the terminal equipment carries out the cell measurement of the NR cell according to the first measurement duration parameter. By the scheme, the terminal equipment in the EN-DC system can autonomously configure the first measurement time length and carry out NR cell measurement, so that the terminal equipment can normally carry out cell measurement, and further, the terminal equipment determines the first measurement time length measured by the NR cell according to the current service condition in the service cell, so that the first measurement time length matched with the current service condition can be flexibly determined according to the current service condition of the service cell of the terminal equipment, and the cell measurement of the NR cell is carried out, thereby flexibly realizing the NR cell measurement.

The NR cell measurement method provided in the embodiment of the present invention may be applied to an architecture diagram of an EN-DC system as shown in fig. 3, where the EN-DC system includes a 4G core network device, a 4G base station, a 5G base station, and a terminal device, and the terminal device may access the 4G base station or the 5G base station, so as to implement dual connectivity. In the embodiment of the invention, the terminal equipment is accessed to the 4G base station, the first measurement duration for measuring the NR cell is determined according to the service condition of the service cell under the current 4G base station, and the cell measurement of the NR cell is carried out, so that the terminal equipment can be ensured to normally carry out the cell measurement in an EN-DC system, and the measurement of the NR cell can be flexibly realized.

It should be noted that the schematic architecture of the EN-DC system shown in fig. 3 is only an exemplary illustration, and in practice, the system may include more terminal devices or network devices, and the embodiment of the present invention is not limited thereto.

As shown in fig. 4, an embodiment of the present invention provides a method for measuring an NR cell, where the method includes:

401. the network device indicates the second measurement duration and/or the SMTC to the terminal device.

The network device may indicate the second measurement duration and/or the SMTC under the ENDC system to the terminal device through the indication information according to a specification of a 3GPP protocol.

In the embodiment of the invention, the measurement duration is a time range for measurement.

In the embodiment of the present invention, a time period from a starting time of a time period (i.e., gap) measured at one time to a starting time of a time period measured at the next time is a measurement interval period, which is also referred to as a gap period.

The terminal device in the embodiment of the invention can be a terminal device in a connection state, the terminal device is currently accessed in a 4G base station, and a current service cell is an LTE cell.

The network device may be a 4G base station.

402. And the terminal equipment carries out NR cell measurement according to the second measurement duration and/or the SMTC indicated by the network equipment.

In a possible case where the network device is not configured with the second measurement duration and the SMTC, the following steps 404 to 406 may be directly performed.

Optionally, in the embodiment of the present invention, for a scenario in which the network device does not configure a gap, the NR cell measurement may also be performed with a gap of 80ms as a default.

Another possible situation is that, under the condition that the network device configures the second measurement duration and/or the SMTC, the terminal device may perform NR cell measurement according to the second measurement duration and/or the SMTC configured by the network device.

It is also possible that the second measurement duration configured by the network device does not overlap the SMTC at all, and NR cell measurement may be performed only according to the second measurement duration.

In the embodiment of the invention, aiming at the situation that the gap configured by the network equipment and the SMTC are not overlapped completely, the gap configured by the network equipment is only needed to be used for NR cell measurement, and the SMTC is not needed.

However, when the gap or SMTC window configured by the network device has a large position deviation from the actually existing NR SSB, the terminal device cannot measure the NR cell by relying on the network device configuration to perform NR cell measurement.

Optionally, the position deviation between the gap or SMTC window configured by the network device and the actually existing NR SSB is large, and the method includes the following two specific scenarios:

1. LTE configuration gap and SMTC overlap and are outside the SSB gap location.

2. The LTE configuration gap and SMTC do not overlap and are outside the SSB gap location.

In the case where the gap and/or SMTC window does not correspond to the actual time slot of the NR SSB, even if the terminal device measures the NR cell at the time slot of the gap and/or SMTC window configured in the network device, the terminal device cannot actually measure the NR cell.

For example, as shown in fig. 5, when the gap, SMTC window configured by the network device is outside the location where the NR SSB actually exists, the terminal device may not measure the NR cell by relying on the network device configuration to perform NR cell measurement.

The configuration gap of the network device may be 6ms, and the measurement interval period in LTE may be 40ms or 80ms; the length of the SMTC window configured by the network equipment can be 1ms, 2ms, 3ms, 4ms or 5ms; the SMTC period may be configured by the network device to 20ms; the length of the SSB in an actual NR SSB may be 5ms, the SSB period may be 20ms; in fig. 5, there is an overlap between the gap and SMTC windows of the network device configuration; however, the positions of the gap and SMTC windows configured by the network device do not overlap with the position where the NR SSB actually exists, and the gap and SMTC windows configured by the network device are located outside the position where the NR SSB actually exists.

Fig. 5 further shows the optimized gap of the embodiment of the present invention, and the value of the gap may be greater than or equal to the SSB period and less than or equal to the measurement interval period.

403. The terminal device judges whether an NR cell is measured.

If no NR cell is measured, the following 404 to 406 are performed; if an NR cell is measured, the following 406 is performed directly.

Optionally, in this embodiment of the present invention, after the terminal device measures the NR cell once, if the NR cell is not measured, it is determined that the NR cell cannot be measured by the current network configuration, and then the following steps 404 to 406 are performed.

Optionally, in this embodiment of the present invention, after the terminal device measures the NR cell for the preset number of times, if the NR cell is not measured, it may be determined that the NR cell cannot be measured by the current network configuration, and then the following steps 404 to 406 are performed.

The preset times can be set according to actual conditions, and the embodiment of the invention is not limited.

404. The terminal equipment determines a first measurement duration measured by the NR cell according to the current service condition in the service cell.

The service cell is an LTE cell in an EN-DC system.

The method for determining the first measurement duration measured by the NR cell by the terminal device according to the current service condition in the serving cell includes: if the NR cells exist in the preset distance range of the serving cell, the terminal equipment determines a first measurement duration measured by the NR cells according to the current service condition in the serving cell.

The determination that an NR cell exists within the preset distance range of the serving cell may include the following two specific implementation manners:

the first realization mode is as follows:

and determining that the current serving cell is the anchor cell through the system message, and determining that the NR cell exists in the preset distance range of the serving cell.

The terminal device may obtain whether the current serving cell is a 5G anchor cell by receiving the SIB2 message and using the related IE in the SIB2, and if the current serving cell is the 5G anchor cell, it indicates that a 5G cell, that is, an NR cell, exists within a preset distance range of the cell.

The second implementation manner is as follows:

and determining that the NR cell exists in the preset distance range of the current service cell according to the record of the historical access cell of the terminal equipment.

The terminal device determines that the terminal device has been accessed to the NR cell under the condition that the terminal device has been accessed to the current service cell through the record of the historical access cell, and then the preset distance range of the service cell can be determined.

The preset distance range may be set according to actual conditions, and the embodiment of the present invention is not limited.

405. And the terminal equipment carries out the cell measurement of the NR cell according to the first measurement duration parameter.

For different current service situations of the terminal device in the serving cell, the foregoing 404 and 405 may be implemented specifically by the following several situations:

situation one

The serving cell is in pure signaling communication, and has no voice and no data service.

In this case, the measurement interval period can be optimized significantly, and the gap can be adjusted to the measurement interval period once in the connected state.

Optionally, if the terminal device does not have a voice service in the serving cell and does not have a data service, the terminal device uses the gap period as the first measurement duration.

Wherein, the gap period can be 20ms, 40ms, 80ms or 160ms. It should be understood that the gap period may also be set to other possible durations, and the embodiment of the present invention is not limited thereto.

In the embodiment of the present invention, the gap period may be configured for the network device, may also be specified in the communication protocol, and may also be determined for the terminal device.

Further, the terminal device may perform cell measurement of the NR cell once according to the first measurement duration;

if the NR cell is measured, the terminal equipment reports the measured result of the NR cell to the network equipment;

if the NR cell is not measured, the terminal device performs the next cell measurement of the NR cell according to the first measurement duration after the first duration until the NR cell is measured, and reports the measured result of the NR cell to the network device.

The first time period may be set according to actual requirements, for example, set to 1s, 2s, or 3s, and the embodiment of the present invention is not limited in particular.

For example, assuming that the gap period is 80ms, it may be determined that the first measurement duration period is 80ms, then perform NR cell measurement according to 80ms, if an NR cell is measured at one time, directly report the measured measurement result of the NR cell to the network device, if an NR cell is not measured at one time, perform the next measurement at an interval of 2s, and so on, until an NR cell is measured, report the measured measurement result of the NR cell to the network device.

Situation two

There is a Voice service, and a Voice over Long-Term Evolution (Voice over) service is mainly used.

At the moment, the voice quality is the first guarantee, and no optimization can be carried out in the whole volte process.

In an optional implementation manner, if the terminal device has a voice service in the serving cell, the second measurement duration indicated by the network device may be used as the first measurement duration.

Further, according to the second measurement duration and the measurement interval period, performing NR cell measurement periodically until an NR cell is measured, and reporting the measured measurement result of the NR cell to the network device.

Situation three

Presence Data (Data) services

The measurement interval period can be progressively optimized, and the loss of the existing data service is influenced to the minimum extent.

Optionally, if the terminal device has a data service in the serving cell, the first measurement duration is determined according to the SSB period.

In NR, the SSB period will be configured in SIB 1. Alternatively, the SSB period may be configured to be 5ms10ms, 20ms, 40ms, 80ms, or 160ms.

In the embodiment of the present invention, the determined first measurement duration may be a fixed value or a gradually increasing value.

The first measurement duration is greater than or equal to the SSB period, and the first measurement duration is less than or equal to the measurement interval period.

Optionally, the terminal device periodically performs NR cell measurement according to the first measurement duration and the measurement interval period until the NR cell is measured, and reports the measured measurement result of the NR cell to the network device.

Illustratively, the first measurement duration is a fixed value. Assuming that the SSB period is 20ms and the measurement interval period is 80ms, it may be determined that the measurement interval of each period is 20ms, and perform NR cell measurement periodically until an NR cell is measured, and report the measured measurement result of the NR cell to the network device.

Illustratively, for the case where the first measurement duration is a progressively increasing value. Assuming a SSB period of 20ms and a measurement interval period of 80ms, it can be determined that the first measurement duration is 20ms, the first measurement duration in the second measurement interval period is 40ms, and the first measurement duration in the third measurement interval period is 80ms.

Further, for the case where the first measurement duration is a progressively increasing value, the first measurement duration in the subsequent period is greater than the first measurement duration in the previous period.

Optionally, the first measurement duration period is an integral multiple of the SSB period;

the first measurement duration in the previous cycle is n times the SSB cycle;

the first measurement time in the next period is m times of the SSB period;

wherein m is an integer greater than n.

In one case, the NR cell measurement may be periodically performed according to the first measurement duration and the measurement interval period until a difference between the first measurement duration and the measurement interval period in a certain measurement interval period is smaller than a preset difference, and a measurement result of the measured NR cell is reported to the network device when the NR cell is measured in a current measurement interval period.

In another case, the NR cell measurement may be performed periodically according to the first measurement duration and the measurement interval period; and performing the step of periodically measuring the NR cells according to the first measurement time length and the measurement interval period after the second time length until the NR cells are not measured in the current measurement interval period and the difference value between the first measurement time length and the measurement interval period in the current measurement interval period is less than the preset difference value.

The first time period may be set according to an actual requirement, for example, set to 1s, 2s, or 3s, and the embodiment of the present invention is not limited in particular.

Illustratively, assuming that the measurement interval period is 80ms, with 20ms as the minimum measurement unit, the first measurement round measures (20 + 1) ms first, if no NR cell is measured in the first measurement round interval period, the second measurement round measures (40 + 1) ms, and if no NR cell is measured in the second measurement round interval period, the third measurement round measures 80ms, so that at most X measurements are required to complete the measurement under any network configuration. Where X = Log2< T (gap)/10 >, T (gap) being the measurement interval period value.

If the NR cell is measured in the third round of measurement, the terminal device sends a measurement result of the NR cell to the network device; if the NR cell is measured in the third round of measurement, the terminal device transmits the measurement result of the NR cell to the network device.

Wherein, adding adds an offset value (1 ms) on the basis of the measuring interval, and the offset value is used for preventing the situation that the boundary of the measuring interval has incomplete synchronization due to the time difference of interaction with the network equipment in the extreme situation.

It should be understood that the offset value is not limited to 1s in the embodiment of the present invention, and the offset value may be set to other values according to practical situations, and the embodiment of the present invention is not specifically exemplified.

406. And the terminal equipment reports the measured measurement result of the NR cell to the network equipment.

Wherein, the measurement result includes at least one of the following information for the NR cell:

(1) Reference Signal Received Power (RSRP);

(2) Reference Signal Receiving Quality (RSRQ);

(3) The Signal-to-Interference plus Noise Ratio (SINR) is the Ratio of the received strength of a useful Signal to the strength of an interfering Signal (Noise and Interference).

Of course, the above measurement result may also include more other information of the NR cell, which is not described herein again.

When the measurement result meets the B1 measurement report condition of the inter-system NR, the measurement result is sent to the network device.

According to the NR cell measuring method provided by the embodiment of the invention, terminal equipment determines a first measuring time length measured by the NR cell according to the current service condition in a service cell, wherein the service cell is an LTE cell in an EN-DC system; and the terminal equipment carries out the cell measurement of the NR cell according to the first measurement duration parameter. By the scheme, the terminal equipment in the EN-DC system can autonomously configure the first measurement time length and perform NR cell measurement, so that the terminal equipment can normally perform cell measurement, and further, the terminal equipment determines the first measurement time length of the NR cell measurement according to the current service condition in the service cell, so that the first measurement time length matched with the current service condition can be flexibly determined to perform the cell measurement of the NR cell according to the current service condition of the service cell of the terminal equipment, and the NR cell measurement can be flexibly realized.

Further, in this embodiment, NR cell measurement may be performed according to the gap and/or SMTC configured by the network device, and when no NR cell is measured, it is considered that the NR cell measurement may be caused by the gap and/or SMTC configured by the network device not corresponding to the actual SSB location, and the terminal device may determine the measurement interval by itself and perform NR cell measurement according to the measurement interval determined by itself. The method can make up for the defects in the current network environment, a set of new 5G blind test algorithm is not completely started, and the default configuration according to the 3GPP protocol specification can be set before the abnormal configuration of the network equipment can not be judged, so that the 5G NR cell measurement with the default rule can be carried out. When it is determined that there is an anomaly in the configuration of the network device, which makes it impossible to measure an NR cell, the solution in the embodiment of the present invention may be enabled for optimization.

In the embodiment of the invention, an optimization strategy of 5G terminal equipment is provided: when the network equipment measurement configuration in the NR is abnormal, the terminal equipment can intelligently measure the 5G cell, so that the 5G network can be quickly used, and the user experience under the NR network is improved.
