Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless communication technology, and in particular to a conditional switching method and device. Background Art
[0002] With the development and changes of mobile communications, 5G (the 5th generation mobile communication) networks have put forward higher requirements for latency, especially ultra-reliable and low latency communications (URLLC), which need to achieve end-to-end latency of ten milliseconds to support emerging business applications such as autonomous driving, industrial Internet, augmented reality and virtual reality. On the other hand, 5G networks use higher frequency bands. Compared with 4G (the 4th generation mobile communication technology) cells, 5G cells have a smaller radius and an increased number. Therefore, HO (Handover) caused by UE moving in a connected state will be more frequent, bringing unprecedented challenges to the operation and maintenance of 5G networks. The traditional non-conditional handover mechanism is designed for low-frequency band non-dense cell deployment. With the evolution of network capacity expansion, heterogeneous networks are also deployed on top of homogeneous networks. The dense deployment of many cells leads to many choices when performing handovers. Therefore, in order to overcome the end-to-end switching delay problem and better adapt to dense networking scenarios, the CHO (Conditional Handover) mechanism was proposed in the R16 version of the 3GPP 4G / 5G system.
[0003] Although R16 introduces the CHO mechanism, if the base station sends too many candidate target cells to the UE (User Equipment), multiple candidate target cells will reserve resources for the UE, causing resource waste. In addition, if the base station sends too few candidate target cells to the UE, the UE may not be able to switch to a suitable cell in time, thus failing to reduce the switching delay.

[0105] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.
[0106] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.
[0107] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0108] In the 3GPP protocol R16 version, a conditional handover (CHO) mechanism is introduced. The source cell configures multiple candidate target cells for the UE to be handed over. When the UE receives the conditional handover configuration, it starts to evaluate the execution conditions. When the UE meets one or more handover execution conditions, the UE switches to the target cell. The relevant flowchart is as follows Figure 1 , flow chart of conditional switching specified in 3GPP protocol 38.300.
[0109] like Figure 1 As shown, the 5G network includes functions such as AMF (Access and Mobility Management Function) and UMF (user management function).
[0110] The UE and the network device (such as the source gNB) interact through measurement control and reporting, and the network device (such as the source gNB) makes the CHO decision. Although 3GPP protocol 38.300 specifies the process of conditional switching, there are no specific regulations for measurement control and CHO decisions. Therefore, how to control the UE measurement and screening of candidate target cells will directly affect whether the performance of CHO can meet expectations.
[0111] In the existing scheme, UE measurement is not specifically optimized, but simply screened according to the results of the UE's general measurement process. For example, the neighboring cells' Reference Signal Receiving Power (RSRP) values reported by the measurement are sorted, and the cell with the largest RSRP value is determined as the candidate target cell for simple filtering.
[0112] However, this simple filtering scheme is only applicable to the scenario where there are not many 5G base stations at the beginning. As 5G base stations become more and more dense and multi-layer networks are built, there will be many candidate target cells, which is far greater than the maximum value of candidate cells supported by UE capabilities. The results obtained by filtering based on UE capabilities and ordinary measurements may include outdated neighboring cells. Figure 2As shown in the figure, the serving cell of the UE is C. When the UE runs from the junction of cells A and B along the route in the direction of the arrow, cell B is more meaningful than cell A as a candidate target cell. Cell A may even have a negative effect on the handover. For example, if the UE switches to cell A first, because the signal of cell A is not as good as that of cell B, it will cause a quick switch to cell B, which increases the handover probability and thus affects the service perception.
[0113] Therefore, the target candidate cells obtained by simple filtering can no longer meet actual needs. In order to more effectively filter out a valid set of candidate target cells from many neighboring cells, it has become a problem that 5G base stations need to solve.
[0114] Based on this, the technical solution of the present application is proposed to solve this problem.
[0115] The core idea of each embodiment of the present application is to use the dedicated measurement configuration information sent by the base station side to control the measurement results of the UE, and filter out a candidate target cell list based on the trend of the measurement results reported by the UE. This solution comprehensively considers the UE capability, the actual number of reported neighboring cells, and the trend of the UE reporting results, and gives a relatively reasonable candidate target cell list, effectively saving network resources.
[0116] The conditional switching control method and device of the present application are described below with reference to specific embodiments.
[0117] Figure 3 This is one of the flow charts of the conditional switching method provided by this application. Figure 3 As shown, the conditional switching method is applied to a network side device, and the method includes:
[0118] Step 301: Receive a measurement report returned by a user terminal based on dedicated measurement configuration information, where the measurement report includes a measurement result of at least one neighboring cell, and the measurement result of each neighboring cell includes at least one type of reported quantity, and each type of reported quantity corresponds to multiple measurement values;
[0119] Specifically, the network side device sends dedicated measurement configuration information, and the dedicated measurement configuration information is used to configure the specific requirements for the UE to send a measurement report, such as how many neighboring cells to measure, and how many types of reporting quantities each neighboring cell contains. The reporting quantity here mainly reflects various parameters of the signal quality of each neighboring cell, which can be one or more of SSB (Synchronization Signalsblock) / CSI-RS (Channel State Information Reference Signal), RSRP, RSRQ (Reference Signal Receiving Quality), RSSI (Received Signal Strength Indication), etc. RSRP is recommended for coverage-limited scenarios, and RSRQ is recommended for interference-limited scenarios. Which or which combination quantities to use can be configured based on test results or experience. How many times each type of reporting quantity needs to be measured, for example 8 times, the more times, the more conducive it is to judge the trend of measurement value changes, but it will also affect the UE switching execution time, and both factors need to be considered comprehensively.
[0120] According to the dedicated measurement configuration information sent by the network side device, the user terminal measures the neighboring area and sends the measurement report to the network side device, and the measurement report includes the measurement result of at least one neighboring area, and the measurement result of each neighboring area includes at least one type of reported quantity, and each type of reported quantity corresponds to multiple measurement values. It is mainly to realize multiple measurements of multiple types of reported quantities of multiple neighboring areas and compare the change trend of related measurement values. Therefore, each neighboring area usually contains multiple types of reported quantities in the measurement results, and there are generally multiple measurement results related to each type of reported quantity, including at least one.
[0121] Step 302: If the number of the neighboring cells is greater than a preset number, obtaining a sorting priority corresponding to each of the neighboring cells based on a plurality of measurement values corresponding to each type of reported quantity of each of the neighboring cells;
[0122] Specifically, in the prior art, the increasing density of 5G base stations and the construction of multi-layer networks have led to too many candidate target cells, which is far greater than the maximum value of the candidate cells supported by the UE capability. Considering the UE capability and improving the utilization of network resources, a preset number N is set to determine whether the UE is in the coverage of a smaller number of neighboring cells (N is configurable, default is 1 to 2). If the number of neighboring cells in the measurement report is greater than the preset number N, it is necessary to first obtain multiple measurement values of each type of reporting quantity corresponding to each of the neighboring cells. In this way, the measurement values of each type of reporting quantity of each neighboring cell can constitute a small set A. i, the measurement values of all reported quantities of each neighboring area can form a large set {A1, A2...A n}, where n represents the number of reports from each neighboring cell. Based on the set {A1, A2...A n}Calculate and obtain the sorting priority corresponding to each neighboring area.
[0123] Step 303: Determine a candidate target cell for conditional switching based on the sorting priority.
[0124] Specifically, for the set {A1, A2...A n}Calculate and obtain the sorting priority corresponding to each neighboring cell, that is, each neighboring cell has its corresponding sorting priority. All neighboring cells in the measurement report have corresponding sorting priorities, forming a set. In this set, candidate target cells for conditional switching are screened according to the set rules. There can be multiple or only one candidate target cell.
[0125] The conditional switching method provided in the embodiment of the present application sends dedicated measurement configuration information through a network side device, controls the number of reported quantities included in the measurement report reported by the UE, the number of measurements of each type of reported quantity, etc., and screens out a list of candidate target cells based on the measurement results reported by the UE. The method comprehensively considers the UE support capability, the number of actually reported neighboring cells, and the trend of the UE reported measurement results, and provides a relatively reasonable list of candidate target cells, thereby effectively saving network resources.
[0126] On the basis of the above embodiment, optionally, obtaining the sorting priority corresponding to each neighboring area based on multiple measurement values corresponding to each type of reported amount of each neighboring area includes:
[0127] Based on the multiple measurement values corresponding to each type of reported amount, obtaining a first priority corresponding to each type of reported amount;
[0128] Based on the first priority corresponding to each type of reported amount, the sorting priority corresponding to each of the neighboring areas is obtained.
[0129] Specifically, each of the neighboring cells may include multiple types of reported quantities, and each type of reported quantity has been measured multiple times to obtain multiple measurement values. For example, the reported quantity is RSRP, and it is measured 5 times, with corresponding results of (-65, -68, -70, -85, -75). Based on this result, the first priority of the RSRP reported quantity is obtained; for example, the reported quantities are RSRP and RSRQ, and they are measured 5 times respectively, with corresponding results of (-65, -68, -70, -85, -75) and (-8, -8.5, -7, -9, -7.5). Based on this result, the first priority of the RSRP reported quantity and the first priority of the RSRQ reported quantity can be obtained respectively.
[0130] And based on the first priority of the RSRP reporting amount and the first priority of the RSRQ reporting amount, the corresponding sorting priority of the neighboring area is determined.
[0131] The conditional switching method provided in the embodiment of the present application can determine the trend of the measurement results reported by the UE by obtaining the measurement report reported by the UE and further processing the measurement results in the measurement report to obtain the sorting priority of each neighboring cell, thereby providing a prerequisite for subsequently determining the candidate target cell list.
[0132] On the basis of the above embodiment, optionally, determining a candidate target cell for conditional switching based on the sorting priority includes:
[0133] The priority of each neighboring cell is sorted from high to low, and a preset number of neighboring cells with the highest priority after sorting are determined as candidate target cells for conditional switching.
[0134] Specifically, after each of the neighboring cells has a corresponding sorting priority, these sorting priorities are sorted from high to low, and the number of candidate target cells is preset in advance, that is, the preset number. In this way, an appropriate number of neighboring cells can be selected as candidate target cells to avoid sending too many candidate target cells to the terminal user and wasting network resources.
[0135] The conditional switching method provided in the embodiment of the present application saves network resources by sorting the sorting priority of each neighboring cell from high to low, and screening the neighboring cells with high priority and appropriate number as candidate target cells.
[0136] Based on the above embodiment, optionally, the method further includes:
[0137] Screening the neighboring cells based on the last measurement value corresponding to each type of reported amount of each neighboring cell and the preset threshold corresponding to each type of reported amount;
[0138] If the number of the neighboring areas after screening is greater than the preset number, a step of obtaining a sorting priority corresponding to each neighboring area based on a plurality of measurement values corresponding to each type of reported amount is performed;
[0139] If the number of the neighboring cells after screening is less than or equal to the preset number, all the neighboring cells are determined as candidate target cells for conditional switching.
[0140] Specifically, each type of reported quantity of each neighboring area is measured multiple times, and the last measurement value is obtained, and compared with the preset threshold of the corresponding reported quantity in the dedicated measurement configuration information, and the neighboring area is screened. It is determined whether the last measurement values of all reported quantities of the neighboring area are greater than the preset threshold of the corresponding reported quantity in the dedicated measurement configuration information. If so, it is determined that the neighboring area meets the conditions and the subsequent process can continue. If not, it is determined that the neighboring area does not meet the conditions and does not enter the subsequent process. After the above screening, the number of neighboring areas that can enter the subsequent process can be obtained.
[0141] Taking into account the UE capabilities and improving the utilization of network resources, a preset number N is set to determine whether the UE is within the coverage of a smaller number of neighboring cells (N is configurable, the default is 1 to 2). If the number of neighboring cells after screening is greater than the preset number N, the specific processing method is the same as the description of step 302.
[0142] If the number of the neighboring cells after screening is less than or equal to the preset number N, it means that the number of suitable neighboring cells is small, and all the neighboring cells after screening can be directly determined as candidate target cells for conditional switching.
[0143] The conditional switching method provided in the embodiment of the present application comprehensively considers the UE support capability, the actual number of reported neighboring cells, and the trend of UE reporting measurement results, and provides a relatively reasonable list of candidate target cells, effectively saving network resources.
[0144] Based on the above embodiment, optionally, the acquiring the first priority corresponding to each type of reporting amount based on the multiple measurement values corresponding to each type of reporting amount includes:
[0145] Determine the increment of each type of reported amount based on the difference between the last measured value and the measured values other than the last one among the multiple measured values corresponding to each type of reported amount;
[0146] Determining the weight of the increment of each type of reported amount;
[0147] The first priority corresponding to each type of reporting amount is obtained by combining the increment of each type of reporting amount, the weight of the increment of each type of reporting amount and the last of the multiple measurement values corresponding to each type of reporting amount.
[0148] Specifically, in each of the neighboring areas, each type of reported quantity has multiple measurement values, forming a set A i , for example A i ={a1, a2, a3, a5, a6, a7}, calculate the deltaReportQuantity corresponding to this reported quantity i It can be obtained through a7-a1, a7-a3, a7-a6, etc.
[0149] There may be multiple reported amounts for each neighboring area, and the corresponding weight W of each reported amount can be determined based on experience or field verification. i , weight W i The value range of is [0, 1], where i is the number of reported categories.
[0150] The increment of each category's reported quantity is deltaReportQuantity i Multiply by the corresponding weight W i , plus the last measurement result of this type of report quantity, determine the first priority corresponding to this type of report quantity.
[0151] The conditional switching method provided in the embodiment of the present application comprehensively considers the UE support capability, the actual number of reported neighboring cells, and the trend of UE reporting measurement results, and provides a relatively reasonable list of candidate target cells, effectively saving network resources.
[0152] On the basis of the above embodiment, optionally, obtaining the sorting priority corresponding to each of the neighboring cells based on the first priority corresponding to each type of reported amount includes:
[0153] Determine the weight of the first priority corresponding to each type of reported amount;
[0154] Based on the first priority corresponding to each type of reported amount and the weight of the first priority corresponding to each type of reported amount, the sorting priority corresponding to each neighboring area is obtained.
[0155] Specifically, in order to determine the sorting priority of each neighboring area, all reports of the neighboring area are considered at the same time, and the corresponding weight W is set for the first priority determined by each report amount. k , weight W k The value range is [0, 1], where the maximum value of k is the number of reported quantities and satisfies the weight W for each reported quantity. k The sum is 1.
[0156] Multiply the first priority corresponding to each type of reporting amount by the weight W of the first priority corresponding to each type of reporting amount k , and sum to get the sorting priority corresponding to each neighboring area.
[0157] The conditional switching method provided in the embodiment of the present application comprehensively considers the UE support capability, the actual number of reported neighboring cells, and the trend of UE reporting measurement results, and provides a relatively reasonable list of candidate target cells, effectively saving network resources.
[0158] On the basis of the above embodiment, optionally, after determining the candidate target cell for conditional switching based on the sorting priority, the method further includes:
[0159] sending handover requests to the candidate target cells respectively;
[0160] The candidate target cell is updated according to the successfully received return handover confirmation message.
[0161] Specifically, the network side device sends a handover request to each of the candidate target cells. If the neighboring cell can successfully return a handover confirmation message within the waiting time, the neighboring cell is retained in the candidate target cell.
[0162] Otherwise, the corresponding neighboring cell is deleted from the target cell.
[0163] Finally, the updated candidate target cell is obtained.
[0164] The conditional switching method provided in the embodiment of the present application comprehensively considers the UE support capability, the actual number of reported neighboring cells, and the trend of UE reporting measurement results, and provides a relatively reasonable list of candidate target cells, effectively saving network resources.
[0165] Based on the above embodiment, optionally, the dedicated measurement configuration information includes:
[0166] Lower than the bias or threshold for event reporting of the existing handover measurement configuration;
[0167] The number of incident reports reported;
[0168] The number of times the event was reported.
[0169] Specifically, the dedicated measurement configuration information includes a variety of configuration parameters, commonly used ones include a bias or threshold for event reporting, a reporting amount for event reporting, and / or a reporting number of event reporting.
[0170] The offset of event reporting, such as the same-frequency handover offset A3 offset, indicates the offset value of the neighboring cell quality higher than the serving cell in the same-frequency handover. This parameter indicates the offset value of the neighboring cell higher than the serving cell in the A3 event, which is used to determine the boundary between the neighboring cell and the serving cell. The larger the value, the better the service quality of the target cell is required to initiate the handover. The setting of Offset is to adjust the difficulty of handover. This value is added to the measured value for the evaluation of event triggering and cancellation. Increasing this parameter will increase the difficulty of triggering the A3 event and delay the handover; reducing this parameter will reduce the difficulty of triggering the A3 event and make the handover in advance.
[0171] Event reporting threshold: When the value is above or below a certain value, an event is considered to be triggered.
[0172] The event reporting offset or threshold is lower than that of the existing handover measurement configuration, so that the UE can measure the dedicated measurement configuration information and report the measurement result earlier than the common handover measurement, thereby accelerating the UE handover.
[0173] The reporting amount of the event report can be configured according to the coverage scenario, and the reporting amount can be one or more of SSB / CSI-RS, RSRP, RSRQ, RSSI, etc.
[0174] The reporting times of event reporting controls how many times the user terminal performs measurements on a certain type of reporting quantity of a neighboring cell.
[0175] In order to enable the user terminal to report the measurement result earlier than the common handover measurement, the time reporting offset or threshold can be set to be slightly lower than the common handover. After sending the dedicated measurement configuration information, the existing handover measurement configuration is sent.
[0176] In addition, the timing of RRCReconfiguration sent through the CHO event may be slightly earlier than the normal handover.
[0177] Specifically, the measurement is mainly divided into two types: intra-frequency measurement and inter-frequency measurement. For intra-frequency measurement, two RRCReconfiguration messages are usually sent. CHO can be sent in the first RRCReconfiguration message after the UE successfully accesses the cell; while ordinary handover is sent in the second RRCReconfiguration message.
[0178] For inter-frequency measurement, in normal switching, inter-frequency measurement is usually issued only when the level value of the serving cell is lower than a certain threshold (such as A2 reporting threshold). CHO can set the threshold higher than normal switching, so that CHO will be triggered earlier than normal switching.
[0179] The conditional switching method provided in the embodiment of the present application controls the measurement report reported by the UE through the dedicated measurement configuration information sent by the network side device, and screens out a candidate target cell list according to the measurement result reported by the UE, comprehensively considering the UE support capability, the actual number of reported neighboring cells, and the trend of the UE reporting measurement results, and provides a relatively reasonable candidate target cell list, effectively saving network resources.
[0180] Figure 4 This is the second flow chart of the conditional switching method provided by this application. Figure 4 As shown, the conditional switching method is applied to a user terminal, and the method includes:
[0181] Step 401: receiving dedicated measurement configuration information sent by a network side device;
[0182] Step 402: perform measurement based on the dedicated measurement configuration information and send a measurement report, where the measurement report includes a measurement result of at least one neighboring cell, and the measurement result of each neighboring cell includes at least one type of reported quantity, and each type of reported quantity corresponds to multiple measurement values;
[0183] The measurement report is used for the network side device to determine that the number of the neighboring cells is greater than a preset number, and then based on multiple measurement values corresponding to each type of reporting quantity of each neighboring cell, obtain the sorting priority corresponding to each neighboring cell; based on the sorting priority, determine the candidate target cell for conditional switching.
[0184] Specifically, the user terminal receives the dedicated measurement configuration information sent by the network side device, and the dedicated measurement configuration information is used to configure the specific requirements for the UE to send a measurement report, such as how many neighboring cells to measure and how many reporting quantities each neighboring cell contains. The reporting quantity here mainly reflects the various parameters of the signal quality of each neighboring cell, which can be one or more of SSB / CSI-RS, RSRP, RSRQ, RSSI, etc. RSRP is recommended for coverage-limited scenarios, and RSRQ is recommended for interference-limited scenarios. Which or which combination quantities to use can be configured externally based on test results or experience. How many times each type of reporting quantity needs to be measured, for example 8 times, the more times, the more conducive it is to judge the trend of the measurement value change, but it will also affect the UE switching execution time, and both factors need to be considered comprehensively.
[0185] The user terminal measures all neighboring cells according to the dedicated measurement configuration information sent by the network side device, and sends the measurement report to the network side device, and the measurement report includes the measurement result of at least one neighboring cell, and the measurement result of each neighboring cell includes at least one type of reported quantity, and each type of reported quantity corresponds to multiple measurement values. It is mainly to realize multiple measurements of multiple types of reported quantities of multiple neighboring cells, and compare the change trend of related measurement values, so usually each neighboring cell contains multiple types of reported quantities in the measurement results, and there are generally multiple measurement results related to each type of reported quantity, including at least one.
[0186] And the measurement report sent by the user terminal is used for the network side device to determine that the number of the neighboring cells is greater than the preset number, then based on the multiple measurement values corresponding to each type of reporting quantity of each neighboring cell, the sorting priority corresponding to each neighboring cell is obtained; based on the sorting priority, the candidate target cell for conditional switching is determined.
[0187] The specific processing method and conditional switching method are applied to the same as described in the embodiment of the network side device, and will not be repeated here.
[0188] Based on the above embodiment, optionally, the dedicated measurement configuration information includes:
[0189] Lower than the bias or threshold for event reporting of the existing handover measurement configuration;
[0190] The number of incident reports reported;
[0191] The number of times the event was reported.
[0192] Specifically, the dedicated measurement configuration information includes a variety of configuration parameters, commonly used ones include a bias or threshold for event reporting, a reporting amount for event reporting, and / or a reporting number of event reporting.
[0193] The offset of event reporting, such as the same-frequency handover offset A3 offset, indicates the offset value of the neighboring cell quality higher than the serving cell in the same-frequency handover. This parameter indicates the offset value of the neighboring cell higher than the serving cell in the A3 event, which is used to determine the boundary between the neighboring cell and the serving cell. The larger the value, the better the service quality of the target cell is required to initiate the handover. The setting of Offset is to adjust the difficulty of handover. This value is added to the measured value for the evaluation of event triggering and cancellation. Increasing this parameter will increase the difficulty of triggering the A3 event and delay the handover; reducing this parameter will reduce the difficulty of triggering the A3 event and make the handover in advance.
[0194] Event reporting threshold: When the value is above or below a certain value, an event is considered to be triggered.
[0195] The event reporting offset or threshold is lower than that of the existing handover measurement configuration, so that the UE can measure the dedicated measurement configuration information and report the measurement result earlier than the common handover measurement, thereby accelerating the UE handover.
[0196] The reporting amount of the event report can be configured according to the coverage scenario, and the reporting amount can be one or more of SSB / CSI-RS, RSRP, RSRQ, RSSI, etc.
[0197] The reporting times of event reporting controls how many times the user terminal performs measurements on a certain reporting quantity of a neighboring cell.
[0198] The conditional switching method provided in the embodiment of the present application controls the measurement report reported by the UE, the number of types of reported quantities of the specific measured neighboring cells, the number of measurements, etc., through dedicated measurement configuration information, and comprehensively considers the actual number of reported neighboring cells and the trend of the UE's reported measurement results, thereby providing a prerequisite for subsequently determining a relatively reasonable list of candidate target cells.
[0199] Based on the above embodiment, optionally, the method further includes:
[0200] A candidate cell list sent by the network side device is received, where the candidate cell list includes the candidate target cell.
[0201] Specifically, the user terminal receives the candidate cell list sent by the network side device, for example, the network side device sends the candidate cell list to the UE through a ConditionalReconfiguration signal source, wherein the candidate cell list includes the candidate target cell.
[0202] The user terminal completes the conditional switching process based on the candidate target cell and switches to the corresponding candidate target cell, thereby finding a suitable switching cell more efficiently and implementing the switching process faster.
[0203] The conditional switching method provided in the embodiment of the present application sends dedicated measurement configuration information through a network side device, controls the number of neighboring cells, the number of reported quantities, and the number of measurements of each type of reported quantity included in the measurement report reported by the UE, and screens out a list of candidate target cells based on the measurement results reported by the UE. The method comprehensively considers the UE support capability, the actual number of reported neighboring cells, and the trend of the UE reported measurement results, and provides a relatively reasonable list of candidate target cells, thereby effectively saving network resources.
[0204] The technical solution of this application is described below with specific embodiments. Figure 5 It is the overall flow chart of this application.
[0205] like Figure 5 As shown, according to the UE capability and the neighboring cell list, the dedicated RRM (radio resource management) measurement for the CHO purpose is issued, the neighboring cell list reported by the UE is sorted, the candidate CHO target cell is selected, and a switching request is sent to the candidate CHO target cell. The final CHO target cell is determined based on the cell that successfully returns the switching confirmation, and finally the final CHO target cell is sent to the user terminal to realize the CHO switching.
[0206] Taking into account the UE support capability, the actual number of reported neighboring cells and the trend of UE reported measurement results, a relatively reasonable list of candidate target cells is given to effectively save network resources.
[0207] See the process for detailed technical solutions Figure 6 As shown. Figure 6 As shown:
[0208] Step 1: After the UE initially accesses the network, the CHO capability of the UE is queried.
[0209] According to whether the information source in the following parameters is supported, determine whether the UE capability supports CHO. If supported, continue with the subsequent steps, otherwise do not execute the subsequent steps.
[0210] condHandoverParametersCommon-r16 SEQUENCE{
[0211] condHandoverFDD-TDD-r16 ENUMERATED{supported}
[0212] condHandoverFR1-FR2-r16 ENUMERATED{supported}
[0213] Step 2: For UEs supporting CHO capability, RRM dedicated measurement configuration information corresponding to the CHO purpose is issued.
[0214] The RRM-specific measurement configuration information here is different from the common handover measurement configuration information.
[0215] In order to prevent the UE from switching too late, the RRM dedicated measurement configuration information should be reported earlier than the common switching measurement configuration information.
[0216] This can be done in the following two ways, but not limited to:
[0217] 2.1 Set the offset or threshold value in event reporting to be slightly lower than the offset or threshold of normal switching, as shown in the bold font below. You can also configure it accordingly based on the actual switching event used;
[0218]
[0219]
[0220] 2.2 The timing of sending the CHO event is slightly earlier than the normal switch.
[0221] That is, the RRCReconfiguration time point sent by the CHO event is slightly earlier than the normal handover.
[0222] 2) Reporting quantity.
[0223] The reporting amount can be configured according to the coverage scenario, and can be one or more of SSB / CSI-RS, RSRP, RSRQ, RSSI, etc. RSRP is recommended for coverage-limited scenarios, and RSRQ is recommended for interference-limited scenarios. Which one or which combinations to use can be configured based on test results or experience.
[0224] The usual configuration of the handover reporting times is 1 to 2 times. In order to identify the trend of the reporting volume of neighboring cells, the reporting times of event reporting in the dedicated measurement configuration information of CHO are set to multiple times. For example, 8 times. The more times, the more conducive to judging the trend of the change in the reporting volume, but it will also affect the UE handover execution time. Two aspects of factors need to be considered comprehensively. The commonly used configuration parameters are shown in bold font below.
[0225]
[0226] Step 3: Determine the corresponding priorities for the neighboring cells reported by the UE and sort them from high to low.
[0227] Here, for the sake of simplicity of description, it is assumed that there are two reporting volumes, ReportQuantity1 and ReportQuantity2.
[0228] First, filter out the neighboring cells whose measured values of the last reporting volume meet the conditions:
[0229] LastReportQuantity1>ReportQuantity1Thres
[0230] And LastReportQuantity2>ReportQuantity2Thres (1)
[0231] It is assumed that there are NumAdjCell neighboring cells that meet this condition.
[0232] 2) If the number of neighboring cells NumAdjCell that meet the conditions < N, then the UE is in the coverage range of fewer (N can be configured, default 1 to 2) neighboring cells, and directly use the NumAdjCell neighboring cells as possible candidate target cells and add them to the possible candidate target cell list PosCandiCellList.
[0233] Otherwise, the UE is in the coverage range of multiple neighboring cells, and then filter the possible candidate target cells in the following way and add them to the possible candidate target cell list PosCandiCellList:
[0234] Calculate the corresponding deltaReportQuantity1 and deltaReportQuantity2 for each neighboring cell.
[0235] deltaReportQuantity1 = ReportQuantity1 of the last reported neighboring cell - ReportQuantity1 of the first reported neighboring cell of this neighboring cell.
[0236] deltaReportQuantity2=ReportQuantity2 of the neighboring cell reported for the last time minus ReportQuantity2 of the neighboring cell reported for the first time.
[0237] The priority of each neighboring cell is calculated based on the measurement values of different reported amounts reported multiple times.
[0238] The overall trend can be viewed based on the measurement results. Due to the influence of small-scale fading, the trend of the change in the measurement report amount of the mobile UE is a spiral upward or downward process. The measurement results can be compared multiple times, for example, each measurement result is compared with the previous one, and then the overall increase or decrease ratio is viewed.
[0239] For simplicity, only the first and last reported amounts are referenced here, but the judgment method is not limited to this method:
[0240] Priority1 = ReportQuantity1 reported last time + W1 × deltaReportQuantity1 (2)
[0241] Priority2 = ReportQuantity2 reported last time + W2 × deltaReportQuantity2 (3)
[0242] Priority=W3×Priority1+W4×Priority2 (4)
[0243] in:
[0244] W1 and W2 are the weights of reported quantity 1 and reported quantity 2 of a neighboring area respectively, and the value range is [0, 1], which can be determined based on experience or field verification.
[0245] W3 and W4 are the weights of the priority Prior1 of ReportQuantity1 obtained according to formula (2) and the priority Prior2 of ReportQuantity2 obtained according to formula (3) in the overall priority Priority, respectively. The value range is [0, 1], and the sum of the two is 1.
[0246] When only one reported quantity is measured, Priority 1 can be directly used as the overall priority, that is, Priority 2 is 0 and W3 is 1.
[0247] Sort each neighboring cell from high to low according to priority. Assume that the neighboring cells after sorting are SortAdjCellList.
[0248] The first M neighboring cells with the highest priority are selected as possible candidate target cells and added to the possible candidate target cell list PosCandiCellList. The value of M is the minimum value between the number of neighboring cells supported by the UE and the number of neighboring cells supported by the network side device.
[0249] 3) Send switching requests to the neighboring cells in PosCandiCellList respectively.
[0250] If the neighboring cell can successfully return a handover confirmation message within the waiting time, the neighboring cell will be added to the final CHO candidate target cell list CandiCellList.
[0251] Otherwise, the corresponding neighboring cell is not added to the final CHO candidate target cell list.
[0252] 4) Wait until all neighboring cells in PosCandiCellList have processed the handover request results.
[0253] Step 4: The serving cell sends the CandiCellList as a candidate switching target cell list to the UE.
[0254]
[0255] In order to further illustrate the technical solution of the present application, especially the CHO dedicated measurement configuration and how to screen the target candidate cells, a specific implementation example is provided in which a reporting quantity ReportQuantity is configured for each neighboring cell and the UE has CHO switching capability.
[0256] Step 1: Assume that the normal handover measurement event is A3 and the three parameters under ReportConfigNR source in RRCReconfiguration->measConfig are configured as follows:
[0257] The offset a3-Offset of the A3 event is configured as -3;
[0258] The reporting quantity reportQuantityCell is configured as RSRP;
[0259] The reporting number reportAmount is configured to 1.
[0260] In the CHO dedicated measurement, the three parameters under ReportConfigNR source in RRCReconfiguration->measConfig are configured as follows:
[0261] The offset a3-Offset of the A3 event is configured as -1;
[0262] The reporting quantity reportQuantityCell is configured as RSRP;
[0263] The reportAmount value is set to 4.
[0264] That is, the CHO dedicated measurement is triggered earlier than the common switching, and the reporting times are configured to be multiple times.
[0265] Step 2: Confirm the priority of the neighboring cells included in the measurement results reported by the UE, and sort them from high to low as candidate target cells.
[0266] Assume that the preset number N for screening neighboring cells is 2, and the preset number M of cells with the highest priority when sorting candidate target cells is 4. Here, it is assumed that the neighboring cells and ReportQuantity values reported by the UE are:
[0267] Neighboring area A: -90, -92, -92, -94.
[0268] Neighboring area B: -90, -88, -86, -86.
[0269] Neighborhood C: -87, -90, -92, -94.
[0270] Neighboring area D: -93, -90, -87, -86.
[0271] Neighboring area E: -93, -90, -92, -90.
[0272] The UE reports 5 neighboring cells, which is greater than 2. Therefore, M neighboring cells should be screened out according to the screening scheme and added to the PosCandiCellList.
[0273] a) Calculate the deltaReportQuantity corresponding to each neighboring area.
[0274] deltaReportQuantity=reportQuantity of the neighboring cell reported for the last time minus reportQuantity of the neighboring cell reported for the first time.
[0275] deltaReportQuantity of neighboring cell A = -94 - (-90) = -4;
[0276] deltaReportQuantity of neighboring cell B = -86 - (-90) = 4;
[0277] deltaReportQuantity of neighboring cell C = -94 - (-87) = -7;
[0278] deltaReportQuantity of neighboring cell D = -86 - (-93) = 7;
[0279] The deltaReportQuantity of neighboring cell E=-90-(-93)=3.
[0280] b) Calculate the priority of each neighboring cell. Here, it is assumed that W1 is configured as 1.
[0281] Priority = ReportQuantity value reported last time + W1 × deltaReportQuantity;
[0282] The priority of neighboring cell A = -94 + (-4) = -98;
[0283] The priority of neighboring cell B = -86 + 4 = -82;
[0284] The priority of neighboring cell C = -94 + (-7) = -101;
[0285] The priority of neighboring cell D = -86 + 7 = -79;
[0286] The priority of neighboring cell E = -90 + 3 = -87.
[0287] c) Sort each neighboring area by priority from high to low.
[0288] The sorted neighbor cell list SortAdjCellList is {D, B, E, A, C}.
[0289] d) Take the first M neighboring cells with the highest priority as possible candidate target cells and add them to the possible candidate target cell list PosCandiCellList.
[0290] Here M is 4, then PosCandiCellList is {D, B, E, A}.
[0291] e) Send switching requests to the neighboring cells in PosCandiCellList respectively.
[0292] If {D, B, E, A} all successfully return a handover confirmation message to the serving cell, {D, B, E, A} are added to the final CHO candidate target cell list CandiCellList.
[0293] Step 3: The serving cell sends the CandiCellList as a candidate switching target cell list to the UE.
[0294] The CandiCellList is sent to the UE through the ConditionalReconfiguration signal source.
