Description

Cell selection method and device

Technical Field

The embodiment of the application relates to the field of communication, in particular to a cell selection method and device.

Background

Currently, the conventional frequency band of the fourth generation mobile communication is mainly concentrated below 3GHz, and as the number of terminals sharply increases, the frequency spectrum of the band is very crowded. In comparison, the available spectrum resources in the high frequency band (e.g., the millimeter wave band) are very abundant, which can effectively alleviate the problem of spectrum congestion in the low frequency band, and support the huge demands of the fifth generation mobile communication technology (5 f-generation, 5G) on capacity and transmission rate.

However, compared to the low frequency band, the path loss and the penetration loss of the high frequency band channel are relatively large, and in order to achieve long-distance coverage and space/time frequency signal interference isolation, generally, the receiving and/or transmitting sides of the base station and/or the terminal need to perform Beamforming (Beamforming) operation, that is, a beam is directionally transmitted/received by using a multi-antenna phase technique to increase the coverage distance of the high frequency band signal.

As shown in fig. 1, unlike omni-directional Beam coverage in conventional Long Term Evolution (LTE) technology, Beam scanning (Beam Sweep) is available in 5G to achieve cell coverage, where each cell may include 64 beams at most.

In the existing 5G New Radio (NR) access technology, the cell quality evaluation for each cell is usually performed as follows: the terminal selects M beams (beams) with the best signal quality, the signal quality of which is greater than a signal quality threshold configured on the network side, and the average value of the signal qualities of the M beams is taken as a signal quality result of the cell.

In a cell quality evaluation method in the prior art, if there are a small number of beams, and even the evaluation result of a single Beam cell may be better than the evaluation result of a multi-Beam cell, but if a terminal accesses a single Beam or a small number of beams cell, the terminal may have a Radio Link Failure (RLF) problem.

Disclosure of Invention

The application provides a cell selection method and a cell selection device, which can reduce the probability of RLF problem to a certain extent.

In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, an embodiment of the present application provides a method for selecting a cell, where the method includes: and the terminal receives a configuration message sent by the network side, wherein the configuration message comprises frequency point information and a Beam signal quality threshold. And then, the terminal responds to the received configuration message and carries out cell measurement on the frequency points indicated by the frequency point information so as to obtain the signal quality of at least one Beam of the adjacent cell corresponding to the frequency points. Subsequently, the terminal determines the cell service quality of the neighbor cell based on the signal quality of at least one Beam of the neighbor cell. And when the cell service quality of the adjacent cell is greater than a first preset value and the number of the at least one Beam which is greater than the Beam signal quality threshold is less than a second preset value, the terminal inhibits the sending of the measurement report of the adjacent cell.

Based on the mode, the terminal can suppress the measurement report of the cell which does not meet the expectation, so that the probability of physical layer faults and RLF problems is reduced.

In one possible implementation, the method further includes: and when the cell service quality of the neighbor cell is greater than a first preset value and the number of the at least one Beam which is greater than the Beam signal quality threshold is greater than or equal to a second preset value, the terminal sends a measurement report of the neighbor cell to the base station.

Based on the mode, the probability that the terminal accesses the cells with a large number of beams is realized, so that the probability of RLF is further reduced.

In a possible implementation manner, the first preset value is that a difference value between a cell service quality of a neighboring cell and a cell service quality of a serving cell is smaller than a preset difference threshold, wherein the cell service quality of the serving cell is larger than a difference cell absolute threshold; the cell quality of service of the serving cell is derived based on a signal quality of at least one Beam of the serving cell.

Based on the above manner, the pre-screening of the neighbor cells is realized, that is, in the present application, only when the quality of service of the neighbor cells is greater than the first preset value, or it can be understood that the quality of service of the neighbor cells can meet the requirement of providing service for the terminal, other optimization operations can be continuously performed.

In a possible implementation manner, the second preset value is the number of beams with signal quality greater than a Beam signal quality threshold in the serving cell.

Based on the above manner, the probability that the terminal accesses the neighbor cell is reduced under the condition that the neighbor cell does not meet the expectation, namely the quantity of beams is small, so as to continuously reside in the current service cell, thereby reducing the probability of physical layer faults and RLF problems.

In a possible implementation manner, the configuration message further includes an evaluation duration and a measurement reporting threshold, and the method further includes: the terminal evaluates the adjacent area according to the evaluation duration and the measurement reporting threshold; if the cell service quality of the adjacent cell is less than the measurement reporting threshold, increasing the cell service quality of the adjacent cell to be greater than the measurement reporting threshold; and after the evaluation of the adjacent cell is finished, the terminal sends a measurement report to the base station.

Based on the mode, the terminal can optimize the neighbor cells meeting the expectation, namely the neighbor cells with a large number of beams, so that the neighbor cells meet the measurement reporting conditions.

In one possible implementation, the method further includes: the terminal receives switching indication information sent by the base station, wherein the switching indication information is used for indicating the terminal to access the adjacent cell; and the terminal responds to the switching indication information and accesses the adjacent cell.

Based on the mode, the switching of the neighbor cells meeting the expectation that the quantity of beams exceeds the second preset value is realized, so that the terminal can be accessed into the cells with more beams, and the RLF problem occurrence probability is reduced.

In a possible implementation manner, the configuration message further includes an evaluation duration and a measurement reporting threshold, and the method further includes: the terminal evaluates the adjacent area according to the evaluation duration and the measurement reporting threshold; and after the evaluation of the adjacent cell is finished, the terminal generates a measurement report and inhibits the sending of the measurement report.

Based on the mode, the terminal can suppress the measurement report of the neighbor cell which does not meet the expectation, namely the neighbor cell with less Beam number, and the probability that the terminal accesses the neighbor cell is reduced so as to continuously reside in the current service cell, thereby reducing the probability of physical layer faults and RLF problems.

In a possible implementation manner, the configuring message further includes a Beam quantity threshold, and the determining the cell service quality of the neighboring cell based on the signal quality of at least one Beam of the neighboring cell includes: determining the cell service quality of the neighbor cell based on the signal quality of at least one reference Beam of the neighbor cell, wherein the cell service quality of the neighbor cell is the average value of the signal quality of the at least one reference Beam, the at least one reference Beam belongs to the at least one Beam, the signal quality of the at least one reference Beam is greater than a Beam signal quality threshold, and the number of the at least one reference Beam is less than or equal to a Beam number threshold.

In order to make the technical solutions in the present application better understood, the following briefly describes the background art that may be involved.

As described above, 5G employs multi-beam technology, with one or more beams present per cell to achieve coverage of the cell by the one or more beams. With reference to the communication system in fig. 2, generally speaking, a terminal may obtain signal quality of each Beam of a serving cell and signal quality of each Beam of a neighboring cell in a cell measurement process, for example, the serving cell is a cell 1 in a base station a, the neighboring cell is a cell 2 in a base station B, the terminal may obtain service quality of the cell 1 (i.e., the serving cell) based on the signal quality of each Beam of the cell 1, and obtain service quality of the cell 2 (i.e., the neighboring cell) based on the signal quality of each Beam of the cell 2, and a specific calculation manner will be described in detail in an embodiment of the present application.

The cell measurement process is a necessary process for data communication between the terminal device and the network device, when the terminal device resides in the cell 1, the network side can send a measurement configuration message to the terminal device, so that the terminal performs measurement of the neighboring cells, the neighboring cells usually include inter-system cells and inter-system cells, the terminal device performs measurement of the neighboring cells according to the measurement configuration message sent by the network device, and when a preset condition is met, a corresponding event or a measurement report is reported. Such as an A3 event or an a4 event specified within the protocol, etc.; furthermore, the network device performs cell switching and other steps according to the events reported by the terminal device, so that the terminal device can always reside in the cell with better signals, and the user can enjoy better communication service.

Fig. 4 is a schematic flowchart of an exemplary cell handover, and with reference to fig. 4, the exemplary cell handover specifically includes:

1) the network side sends a configuration message to the terminal. Specifically, the configuration message may also be Radio Resource Control (RRC), including but not limited to: identification information of frequency points, a measurement threshold, measurement reporting conditions and the like. The measurement reporting condition includes, but is not limited to, an evaluation duration and a measurement reporting threshold.

2) And the terminal performs cell measurement based on the configuration message. Specifically, the terminal may perform cell measurement based on the configuration message, specifically perform cell measurement on the frequency point indicated by the network side, so as to obtain the signal quality of Beam of at least one neighboring cell under the frequency point. It should be noted that in some embodiments, the terminal device may also actively initiate the measurement.

3) And the terminal determines the service quality of the adjacent cell based on the acquired quality of the Beam signal of the adjacent cell. The specific determination manner will be described in detail below.

4) And the terminal evaluates the adjacent region. Specifically, the terminal evaluates the service quality of the neighboring cell within the evaluation duration indicated by the network side.

5) And the terminal reports the measurement report of the adjacent cell to the network side. Specifically, after the terminal completes the evaluation of the neighboring cell, it reports the measurement report of the neighboring cell to the network side (specifically, the base station). And if the evaluation of the adjacent cell fails, the measurement report of the adjacent cell is not reported.

6) And the network side instructs the terminal to switch to the adjacent cell. Specifically, the network side, after determining that the neighboring cell can provide service for the terminal based on the received measurement report, may instruct the terminal to switch to the neighboring cell.

Referring to fig. 4, in an example, if the service quality of the neighboring cell, that is, the cell 2, meets the measurement report condition, the terminal reports the measurement report of the cell 2 to the base station, and the base station may instruct the terminal to switch to the cell 2 based on the measurement report reported by the terminal. In this example, if the number of beams of the cell 2 is small, for example, if the number of beams includes only 2 beams, after the terminal accesses the cell 2, if the receiving or transmitting angle of the terminal changes, the coverage angle range of the terminal is small due to the small number of beams of the cell, and therefore, a physical layer failure or RLF problem of the terminal may be caused. The physical layer failure refers to the loss of synchronization of the bottom layer, or called as physical layer loss of synchronization.

Still referring to fig. 4, in another example, if the quality of service of the cell 2 does not satisfy the measurement report condition, the terminal does not report the measurement report of the cell 2 and still resides in the current serving cell, i.e., the cell 1. In this example, if the number of beams of cell 1 is small, for example, only 2 beams are included, the terminal camps on the current serving cell, and there is an RLF problem.

In view of the above problems, the present application provides a cell selection method, so as to expect that a terminal accesses a cell that meets a terminal access requirement and has a large number of beams, thereby avoiding an RLF phenomenon to a certain extent.

Specifically, in the present application, the terminal performs cell measurement to obtain the signal quality of Beam of each of one or more neighboring cells. The terminal can obtain the service quality of each cell based on the Beam signal quality of each cell, and the specific obtaining mode is as follows:

1) and the terminal detects the Beam with the signal quality greater than the Beam signal quality threshold configured at the network side in the plurality of acquired beams of the cell. For example, the number of beams acquired by the terminal to the serving cell is 10, the Beam signal quality threshold configured on the network side is-100 dBm, and the terminal may compare the signal quality of the beams of the serving cell with the Beam signal quality threshold one by one, and determine N beams, for example, 8 beams, whose signal quality is greater than the Beam signal quality.

2) And the terminal selects M beams with the best service quality from the N beams based on the Beam quantity threshold configured on the network side. For example, still taking the parameters in 1) as an example, there are N beams in the serving cell, that is, 8 beams whose signal quality exceeds the Beam signal quality threshold, and assuming that the number threshold of beams configured on the network side is M ═ 5, the terminal selects 5 beams with the best signal quality from the 8 beams for use in the service quality calculation of the subsequent cell, alternatively, M beams may be referred to as reference beams in this application. M is a positive integer less than or equal to N.

3) And the terminal averages the signal quality of the M beams to be used as the service quality of the cell. For example, the terminal averages the signal quality of 5 reference beams, for example, the result is-90 dBm, which is the service quality of the cell.

In each embodiment of the present application, Reference Signal Receiving Power (RSRP) is taken as an example of Beam Signal quality and cell service quality. In other embodiments, the parameters for measuring the quality of the Beam signal and the quality of service of the cell may further include at least one of: signal to Interference plus Noise Ratio (SINR), Reference Signal Received Quality (RSRQ), etc., and the specific requirements may be configured according to the network side, which is not limited in the present application.

Specifically, in the present application, after the terminal obtains the service quality of each cell, it may determine whether the service cell and the neighboring cell meet the terminal access requirement based on the service quality of each cell, including the service quality of the service cell and the neighboring cell. Specifically, the terminal may determine whether the service quality of the serving cell and the service quality of the neighboring cell satisfy the access condition by determining whether the service quality of the serving cell and the service quality of the neighboring cell satisfy the access requirement of the terminal.

Optionally, the access condition may be that the service quality of the neighboring cell is greater than a preset value. That is to say, when the quality of service of the neighboring cell is greater than the preset value, it can be considered that the neighboring cell can provide service for the terminal, that is, the access requirement of the terminal is met. For example, the access condition may specifically be that a difference between the service quality of the serving cell and the service quality of the neighboring cell is smaller than a preset difference threshold, and the service quality of the serving cell is higher than a difference cell absolute threshold.

In a possible implementation manner, if the terminal determines that the serving cell and the neighboring cell satisfy the access condition, the terminal may further detect whether the neighboring cell satisfies the optimization condition.

In another possible implementation manner, if the serving cell and the neighboring cell do not satisfy the access condition, including that a difference between the service quality of the serving cell and the service quality of the neighboring cell is greater than a preset difference threshold, and/or the service quality of the serving cell is less than a difference cell absolute threshold, the terminal performs processing according to a prior art procedure, that is, in an example, if the service quality of the serving cell is much worse than the service quality of the neighboring cell, or the service quality of the serving cell is much better than the service quality of the neighboring cell, that is, a difference between the service quality of the serving cell and the service quality of the neighboring cell is greater than a preset difference threshold, the terminal performs processing according to a prior art procedure. In another example, if the service quality of the serving cell is very poor, i.e. the service quality is less than the poor cell absolute threshold, the terminal also processes according to the prior art procedure. It can be understood that if the service quality of the serving cell is poor, the terminal is expected to access the neighboring cell with better service quality, and the influence of the Beam quantity on the transmission quality of the terminal is ignored.

Specifically, the optimization conditions are the quantity of beams with signal quality greater than a Beam signal quality threshold in the neighbor cell and the quantity of beams with signal quality greater than the Beam signal quality threshold in the service cell.

In one example, if the terminal determines that the neighboring cell does not satisfy the optimization condition, that is, the number of beams having signal quality greater than the Beam signal quality threshold in the neighboring cell is less than or equal to the number of beams having signal quality greater than the Beam signal quality threshold in the serving cell, the terminal suppresses the measurement report of the neighboring cell, that is, does not report the measurement report of the neighboring cell to the base station, and the specific details may refer to scenario one.

In another example, if the terminal determines that the neighboring cell satisfies the optimization condition, that is, the number of beams having signal quality greater than the Beam signal quality threshold in the neighboring cell is greater than the number of beams having signal quality greater than the Beam signal quality threshold in the serving cell, the gain of the neighboring cell is increased to make the neighboring cell satisfy the measurement reporting condition configured on the network side, and a measurement report of the neighboring cell is reported to the base station, so that the terminal accesses the neighboring cell, and the specific details can refer to the second scenario.

For example, the preset difference threshold may be 5dBm, and the specific value may be set according to an actual requirement, which is not limited in the present application. It should be noted that, if the service quality of the serving cell is greater than the service quality of the neighboring cell, the difference between the service quality of the serving cell and the service quality of the neighboring cell means that the service quality of the serving cell is reduced by the service quality of the neighboring cell, and conversely, the service quality of the neighboring cell is reduced by the service quality of the serving cell. Optionally, in this application, it may also be understood that an absolute value of a difference between the service quality of the serving cell and the service quality of the neighboring cell is smaller than a preset difference threshold.

For example, the absolute threshold of the difference cell may be-110 dBm, and the specific value may be set according to actual requirements, which is not limited in this application.

Alternatively, the preset difference threshold and the difference cell absolute threshold may be stored in the terminal.

The technical solutions of the above method embodiments are described in detail below using several specific examples.

Scene one

Referring to fig. 2, as shown in fig. 5, an application scenario diagram in the present embodiment is shown, and for example, in the present embodiment, a base station a includes a cell 1, a base station B includes a cell 2, and the cell 1 is a serving cell of a terminal. With reference to fig. 5, as shown in fig. 6, a schematic flow chart of a cell selection method in the embodiment of the present application is specifically:

step 101, a terminal receives a configuration message sent by a network side.

Specifically, the terminal accesses to the cell 1, and in a connected state, the terminal may receive a configuration message sent by the network side, that is, the base station a, where the configuration message includes, but is not limited to, identification information of at least one frequency point, a measurement threshold, a Beam signal quality threshold, a Beam quantity threshold, and a measurement reporting condition of an a3 event.

Optionally, the measurement threshold is used to indicate whether the terminal needs to perform cell measurement, and it should be noted that the cell measurement described herein refers to performing cell measurement on a non-serving cell, and the measurement of a serving cell is performed continuously, for example, the terminal periodically measures the service quality of the serving cell. In one example, if the quality of service of the serving cell is greater than the measurement threshold, the terminal need not perform cell measurements. In another example, if the service quality of the serving cell is less than the measurement threshold, the terminal performs cell measurement on at least one frequency point configured on the network side, that is, step 102.

Optionally, the measurement reporting condition of the a3 event is used to indicate whether the terminal reports the measurement report of the neighboring cell. Specifically, if the service quality of the neighboring cell meets the measurement reporting condition of the A3 event, the terminal reports the A3 event, the measurement report of the serving cell, and the measurement report of the neighboring cell to the base station a, where the measurement report includes, but is not limited to, the service quality of the cell. It should be noted that, if the terminal reports an A3 event, it is indicated that the terminal needs to switch to another neighboring cell, and it can also be understood that the current serving cell is no longer suitable for the terminal to access, so that the base station receives the A3 event reported by the terminal and the measurement report of the neighboring cell, and instructs the terminal to switch to the neighboring cell. It should be further noted that, the present application is only described in the context of the event A3, and the present application is also applicable to the event a4 or the event a5, and the specific details are similar to those of the event A3, and are not described herein again.

Exemplary reporting conditions for the a3 event include, but are not limited to: the evaluation duration and the A3 event measurement reporting threshold. Specifically, after the terminal acquires the service quality of the cell, the terminal may perform the evaluation of the service quality of the cell, and in the evaluation process, the terminal may evaluate whether the service quality of the neighboring cell is greater than the service quality of the serving cell, and a difference between the service quality of the neighboring cell and the service quality of the serving cell is greater than an A3 event measurement reporting threshold, for example, the A3 event measurement reporting threshold may be 3dBm, and the evaluation duration may be 320ms, that is, in 320ms, the terminal continuously acquires the service quality of the neighboring cell and evaluates the service quality acquired each time, and if the service quality of the neighboring cell satisfies the A3 event measurement reporting threshold each time, the terminal may determine that the neighboring cell satisfies the measurement reporting condition of the A3 event. It should be noted that the parameters in the measurement reporting condition of the A3 event, including the evaluation duration and the A3 event measurement reporting threshold, are merely illustrative examples, and specific values may be set according to actual requirements, which is not limited in this application.

Specifically, in the present application, a terminal may periodically or in real time acquire service quality of a serving cell, refer to fig. 7, which exemplarily shows a schematic diagram of measurement results of a cell 1 and a cell 2 acquired by the terminal, and specifically, a schematic diagram of signal quality of each Beam of the serving cell, that is, the cell 1, where the Beam acquired by the terminal to the cell 1 includes Beam a1, Beam a2, Beam a3, Beam a4, and Beam a5, and in this embodiment, the signal quality of the Beam and the service quality of the cell are taken as reference values for explanation.

Referring to fig. 7, the terminal may detect that Beam having a signal quality exceeding the Beam signal quality threshold in cell 1 is BeamA1, BeamA2, BeamA3, and BeamA4 based on the method described above. Assuming that the threshold of the number of beams configured on the network side is 5, the terminal determines that the Beam 1, the Beam 2, the Beam 3, and the Beam 4 are reference beams, and obtains the service quality of the cell 1 by averaging the signal quality of the reference beams, as shown in fig. 7.

For example, in this embodiment, after the terminal obtains the service quality of the serving cell, based on the measurement threshold configured on the network side, it is determined that the service quality of the serving cell is less than the measurement threshold, and it is determined to execute step 102, that is, to execute cell measurement on each frequency point.

And 102, the terminal performs cell measurement on each frequency point configured on the network side to acquire the service quality of the adjacent cell.

Specifically, in the present application, the terminal may perform cell measurement on a frequency point configured on a network side to obtain a frequency point measurement result, where the frequency point measurement result includes a cell measurement result of at least one cell under the frequency point. Specifically, the terminal performs cell measurement on each single frequency point configured on the network side, and acquires the signal quality of a single Beam of at least one Beam of each cell.

For example, the manner in which the terminal obtains the signal quality of Beam of each cell, that is, the manner of cell measurement, includes: an RRC layer in the terminal instructs a physical layer in the terminal to perform cell measurement on the frequency point, and illustratively, the RRC layer sends a measurement request message to the physical layer, where the request message may carry identification information of the frequency point. The physical layer measures the frequency point based on the identification information of the frequency point, or can be understood as scanning the frequency point to acquire the Beam signal in the cell under the frequency point, and acquire the signal quality of a single Beam based on the acquired Beam signal, wherein the signal quality includes at least one signal quality parameter, for example: at least one of RSRP, RSRQ, SINR. And then, the physical layer returns the measurement result of the frequency point, namely the quality of the Beam signal of each cell under the frequency point to the RRC layer.

For example, in combination with the application scenario of fig. 2, in this embodiment, after the terminal performs search on a frequency point configured on the network side, the signal quality of the BeamB1 and the BeamB2 obtained in neighboring cells, that is, the cell 2, may refer to fig. 7. The terminal may obtain the service quality of the cell 2 based on the obtained signal quality of each Beam of the cell 2, and the specific obtaining manner may refer to the above, which is not described herein again.

It should be noted that, in this embodiment, only one neighboring cell is taken as an example for description, in other embodiments, the terminal may also measure the quality of Beam signals of multiple cells, and obtain the quality of service of each single cell in the multiple cells, which is the same as that of cell 2 in a specific manner, and details of this application are not repeated.

And 103, the terminal judges whether the serving cell and the adjacent cell meet the access condition based on the service quality of the serving cell and the adjacent cell.

For example, in this embodiment, the terminal stores access conditions in advance (the related concepts may refer to the above), where the access conditions include that a difference between the service quality of the serving cell and the service quality of the neighboring cell is smaller than a preset difference, and the service quality of the serving cell is higher than a difference cell absolute threshold. Illustratively, the preset difference is 5dBm, and the difference cell absolute threshold is-100 dBm. That is, if the difference between the service quality of the neighboring cell and the service cell exceeds 5dBm, or the service quality of the service cell is poor, i.e., lower than the difference cell absolute threshold, the service quality of the cell is taken as a main factor for performing cell handover, and the influence of the Beam quantity on the cell handover is ignored.

Specifically, the terminal determines whether the serving cell and the neighboring cell satisfy the access condition based on the service quality of the serving cell and the service quality of the neighboring cell, and optionally, if the serving cell and the neighboring cell do not satisfy the access condition, the process of the present application is ended, and the terminal performs processing according to the process of the prior art, that is, in an example, if the service quality of the serving cell is better than the service quality of the neighboring cell, and the difference of the service qualities is greater than a preset difference threshold, the terminal does not report a measurement report of the neighboring cell. In one example, if the service quality of the serving cell is lower than the service quality of the cell, and the difference between the service qualities is greater than a preset difference threshold, the terminal reports the measurement report of the neighboring cell. In one example, if the service quality of the serving cell is less than the bad cell absolute threshold, the terminal reports a measurement report of the neighboring cell.

Illustratively, in this embodiment, the terminal obtains the service quality of the serving cell, that is, the service quality of the cell 1 is-95 dBm, and the service quality of the neighboring cell (that is, the cell 2) is-93 dBm. The terminal may detect that the difference between the service quality of the cell 1 and the service quality of the cell 2 is less than 5dBm, and the service quality of the cell 1 is greater than the difference cell absolute threshold (-100dBm), and the terminal determines that the cell 1 and the cell 2 meet the access condition, and performs step 104.

And 104, judging that the adjacent cell does not meet the optimization condition by the terminal, and determining a measurement report needing to suppress the adjacent cell.

Specifically, the terminal determines whether the neighboring cell meets the optimization condition based on the service quality of the neighboring cell, in one example, if the neighboring cell does not meet the optimization condition, the terminal determines that the measurement report of the neighboring cell needs to be suppressed, that is, after the neighboring cell is evaluated, if the evaluation result of the neighboring cell is successful, according to the prior art, the terminal may report the measurement report of the neighboring cell and information such as an a3 event, and the base station may instruct the terminal to switch to the neighboring cell. In this application, if the evaluation result of the neighboring cell that does not satisfy the optimization condition is successful, the terminal suppresses the report of the neighboring cell, that is, does not report the measurement report of the neighboring cell to the base station, so that the terminal continues to reside in the serving cell, or switches to the neighboring cell that satisfies the optimization condition, that is, in this application, after the terminal determines that the measurement report of the neighboring cell needs to be suppressed in step 104, whether to perform the suppression operation specifically is determined after the evaluation process of step 105 is finished, if the evaluation of the neighboring cell in step 105 is successful, step 106 is performed, and if the evaluation of the neighboring cell in step 105 fails, the terminal itself does not report the measurement report of the neighboring cell. In another example, if the neighboring cell satisfies the optimization condition, the specific step refers to scene two.

Specifically, in the present application, the optimization condition is the number of beams with signal quality greater than the Beam signal quality threshold in the neighboring cell, and the number of beams with signal quality greater than the Beam signal quality threshold in the serving cell.

For example, still referring to fig. 7, in this embodiment, the number of beams with signal quality greater than the Beam signal quality threshold in the cell 1 is 4, the number of beams with signal quality greater than the Beam signal quality threshold in the cell 2 is 1, and the terminal determines that the cell 2 does not satisfy the optimization condition, determines that it is necessary to suppress measurement reporting of the cell 2, that is, after performing step 105, performs step 106.

And 105, the terminal evaluates the service quality of the adjacent cell.

Specifically, as described above, the terminal may evaluate the service quality of the neighboring cell based on the measurement reporting condition of the A3 event, including the evaluation duration and the A3 event measurement reporting threshold. If the service quality of the neighboring cell acquired by the terminal meets the A3 event measurement reporting threshold within the evaluation duration, for example, the service quality of the neighboring cell is greater than the service quality of the serving cell, and the difference is greater than or equal to 3dBm, it is determined that the evaluation is successful, otherwise, it is determined that the evaluation is failed.

In one example, if the terminal determines that the neighboring cell satisfies the measurement reporting condition of the event a3 after the evaluation duration is over, step 106 is executed based on the determination result of step 104, that is, it is determined that the measurement report of the neighboring cell needs to be suppressed. In another example, if the terminal determines that the neighboring cell does not satisfy the measurement report condition after the evaluation duration is over, the terminal does not report the measurement report of the neighboring cell to the base station, and continues to evaluate other neighboring cells until all the neighboring cells are evaluated. That is to say, in the present application, if the quality of service of the neighboring cell does not satisfy the optimization condition, after the evaluation is finished, whether the evaluation result is successful or failed, the measurement report of the neighboring cell is suppressed.

For example, in this embodiment, the terminal evaluates the cell 2, specifically, within an evaluation duration, for example, 320ms, the terminal periodically obtains the service quality of the cell 2, where the period may be 1ms, and this period is an exemplary example. And the terminal evaluates the service quality of the cell 2 acquired for multiple times based on the measurement reporting threshold of the A3 event, wherein the measurement reporting threshold of the A3 event is 3dBm, namely the service quality of the adjacent cell is greater than or equal to the service quality of the service cell, namely 3 dBm. After the evaluation duration is over, the terminal determines that the cell 2 meets the measurement reporting condition of the a3 event, that is, the evaluation result is successful.

And 106, the terminal restrains the measurement report of the adjacent cell.

For example, in this embodiment, if the terminal determines that the cell 2 does not satisfy the optimization condition, the terminal does not report the measurement report of the cell 2 to the base station. Compared with the prior art: if the service quality of the cell 2 meets the measurement report condition, the terminal will report the a3 event and the measurement report of the cell 2, and the base station will instruct the terminal to switch to the cell 2, as described above, there will be a physical layer failure and an RLF problem after the terminal accesses the cell 2. According to the method and the device, the measurement report of the cell 2 is restrained, so that the cell 2 cannot be selected as an access cell, and the physical layer fault and the RLF problem can be avoided to a certain extent.

Scene two

With reference to fig. 2, as shown in fig. 8, an application scenario diagram in the present embodiment is shown, for example, in the present embodiment, a detailed description is given by taking an example that a base station a includes a cell 1, a base station B includes a cell 2, and the cell 2 is a serving cell of a terminal, and with reference to fig. 8, as shown in fig. 9, a flowchart of a cell selection method in the present embodiment is specifically shown:

step 201, the terminal receives a configuration message sent by the network side.

Specifically, the terminal may receive a configuration message sent by the network side in a connected state, where the configuration message includes, but is not limited to, identification information of at least one frequency point, a measurement threshold, a Beam signal quality threshold, a Beam quantity threshold, and a measurement reporting threshold of an a3 event.

For example, in this embodiment, the terminal may periodically or in real time obtain the service quality of the serving cell, and as a result, still refer to fig. 7, in this embodiment, the cell 2 is the serving cell, and the service quality of the cell 2 shown in fig. 7 is the service quality of the serving cell.

For other details, reference may be made to step 101, which is not described herein.

Step 202, the terminal performs cell measurement on each frequency point configured on the network side to obtain the service quality of the neighboring cell.

Specifically, in the present application, the terminal may perform cell measurement on a frequency point configured on a network side to obtain a frequency point measurement result, where the frequency point measurement result includes a cell measurement result of at least one cell under the frequency point.

For example, in this embodiment, after the terminal performs a search on a frequency point configured on the network side, the signal quality of neighboring cells, that is, the BeamA1, the BeamA2, the BeamA3, the BeamA4, and the BeamA5 of the cell 1, is obtained, as shown in fig. 7. The terminal may obtain the service quality of the cell 1 based on the obtained signal quality of each Beam of the cell 1, and the specific obtaining manner may refer to the above, which is not described herein again.

For further details, reference may be made to step 102, which is not described herein.

Step 203, the terminal judges whether the serving cell and the neighboring cell meet the access condition based on the service quality of the serving cell and the neighboring cell.

Illustratively, in this embodiment, the terminal determines that the serving cell and the neighboring cell satisfy the access condition based on the service quality of the serving cell, i.e., the cell 2, and the service quality of the neighboring cell, i.e., the cell 1, and executes step 204.

For further details, reference may be made to step 103, which is not described herein.

And step 204, the terminal judges that the adjacent cell meets the optimization condition.

Specifically, in the present application, the optimization condition is that the number of beams having signal quality greater than the Beam signal quality threshold in the neighboring cell is greater than the number of beams having signal quality greater than the Beam signal quality threshold in the serving cell.

Illustratively, still referring to fig. 7, in this embodiment, the terminal detects that the number of beams having signal quality greater than the Beam signal quality threshold in cell 1 is 4, and the number of beams having signal quality greater than the Beam signal quality threshold in cell 2 is 1, that is, the number of beams having signal quality greater than the Beam signal quality threshold in cell 1 is greater than the number of beams having signal quality greater than the Beam signal quality threshold in cell 2, and the terminal determines that cell 1 satisfies the optimization condition, and performs step 206.

For further details, reference may be made to step 104, which is not described herein.

Step 205, the terminal determines the evaluation condition of the neighboring cell.

Specifically, in the present application, the terminal may determine the evaluation condition of the neighboring cell based on the measurement reporting condition configured on the network side. Specifically, as described above, the terminal evaluates the neighboring cell, actually, the service quality of the neighboring cell obtained many times is evaluated within the evaluation duration. In one example, if the service quality of any one neighboring cell acquired by the terminal does not satisfy the measurement reporting condition, for example, the service quality of the neighboring cell does not satisfy the measurement reporting threshold of the a3 event, the terminal may increase the service quality of the neighboring cell before evaluating the service quality of the neighboring cell acquired this time, so that the neighboring cell satisfies the measurement reporting condition. Optionally, the increasing amplitude may be the same or different each time, for example, the increasing amplitude may be fixed to 5dBm, or the corresponding amplitude may be increased based on a difference between the service quality of the neighboring cell and the measurement reporting threshold of the A3 event, for example, the measurement reporting threshold of the A3 event is 3dBm, and if the difference between the service quality of the neighboring cell and the service quality of the serving cell is 2dBm, the terminal may increase the service quality of the neighboring cell by 1dBm, so that the difference between the service quality of the neighboring cell and the serving cell is greater than or equal to 3 dBm.

In another example, if the service quality of the neighboring cell meets the measurement report condition, the terminal does not need to optimize the service quality of the neighboring cell.

In another example, the terminal may increase the quality of service of the neighboring cell by a fixed value, for example, 5dBm, before evaluating the quality of service obtained each time. That is, the terminal increases the quality of service of the neighboring cell no matter whether the quality of service of the neighboring cell meets the measurement reporting threshold of the a3 event.

It should be noted that the range of the increase of the service quality of the terminal to the cell is greater than 0dBm and less than or equal to the preset difference threshold.

For example, in this embodiment, the service quality of the neighboring cell is taken as the measurement reporting threshold of the a3 event, and is higher than the service quality of the serving cell by 3dBm (including 3 dBm). Illustratively, the service quality of the terminal acquiring the neighboring cell, i.e. the cell 1, is-95 dBm, and the service quality of the serving cell, i.e. the cell 2, is-93 dBm. Specifically, the terminal detects that the service quality of the cell 1 is less than the service quality of the cell 2, that is, the service quality of the cell 1 acquired this time does not satisfy the measurement reporting threshold of the A3 event, in this embodiment, after determining that the cell 1 satisfies the optimization condition, the terminal may increase the gain, that is, the service quality, of the cell 1 so that the service quality of the cell 1 satisfies the measurement reporting threshold of the A3 event, for example, the terminal increases the service quality, for example, RSRP, of the cell 1 by 5dBm, so that the service quality of the cell 1 is-90 dBm, the service quality of the cell 1 is greater than the service quality of the cell 2, and a difference between the service quality of the cell 1 and the service quality of the cell 2 is 3dBm, that is, the service quality of the cell 1 satisfies the measurement reporting of the A3 event.

And step 206, the terminal evaluates the service quality of the adjacent cell.

Specifically, the terminal may evaluate the service quality of the neighboring cell based on the measurement reporting condition of the A3 event, including the evaluation duration and the A3 event measurement reporting threshold. If the service quality of the neighboring cell acquired by the terminal meets the A3 event measurement reporting threshold within the evaluation duration, for example, the service quality of the neighboring cell is greater than the service quality of the serving cell, and the difference is greater than or equal to 3dBm, it is determined that the evaluation is successful, otherwise, it is determined that the evaluation is failed. It should be noted that, as described above, the terminal may continuously obtain the service qualities of the multiple neighboring cells within the evaluation duration, and after the terminal performs the service quality of the neighboring cell each time, the terminal repeatedly performs step 206 and step 207, that is, after the evaluation condition of the neighboring cell is determined, the service quality of the neighboring cell obtained this time is evaluated.

In an example, if the terminal determines that the neighboring cell satisfies the measurement reporting condition of the event a3 after the evaluation duration is over, the terminal performs step 207, that is, reports the measurement report of the neighboring cell. In another example, if the terminal determines that the neighboring cell does not satisfy the measurement reporting condition of the event a3 after the evaluation duration is over, the terminal does not report the measurement report of the neighboring cell to the base station, and continues to evaluate other neighboring cells until all the neighboring cells are evaluated.

For example, in this embodiment, in step 205, the terminal increases the service quality of the cell 1, so that the service quality of the cell 1 obtained by the terminal each time meets the measurement reporting threshold of the a3 event within the evaluation duration, after the evaluation duration is ended, the terminal determines that the cell 1 meets the evaluation condition, that is, the evaluation result is successful, and the terminal may perform the reporting process of step 207 on the cell 1.

And step 207, the terminal reports the measurement report of the neighbor cell.

For example, in this embodiment, after the terminal ends the evaluation duration, and it is determined that the cell 1 is evaluated successfully, the terminal reports the a3 event, the measurement report of the cell 1, and the measurement report of the cell 2 to the base station (i.e., the base station 2).

Illustratively, the base station 1 receives a report a3 event reported by the terminal, a measurement report of the cell 1, and a measurement report of the cell 2, and the base station 2 determines that the cell 1 can provide a service for the terminal, and then the base station 1 interacts with the base station 2, which specifically includes that the base station 1 obtains relevant information of the terminal, such as identification information and context information of the terminal, from the base station 2 to prepare for terminal handover, after the base station 1 completes preparation, the base station 2 can send a handover instruction to the terminal, and the handover instruction can carry the identification information of the cell 1 to indicate that the terminal is about to be handed over to the cell 1. The terminal may then switch to cell 1, i.e. to a cell with a higher number of beams, based on the indication of base station 2.

In summary, compared with the prior art in which the measurement report condition is not satisfied and the measurement report is not reported, the method and the device for reporting the measurement report can optimize the service quality of the neighbor cell satisfying the access requirement of the terminal so as to make the service quality conform to the measurement report condition, thereby increasing the probability of serving as the serving cell, enabling the terminal to be switched to the neighbor cell with more Beam numbers, and improving the continuity of terminal communication.
