[0052] 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.

[0053] refer to Figure 1 As shown in FIG. 1 , it is a flow chart of an implementation of a data processing method provided in an embodiment of the present application. The method can be applied to a base station in a cell network, such as Figure 2 The first base station or the second base station shown, the cell network of the first base station is recorded as the first cell, the cell network of the second base station is recorded as the second cell, and the user carries the communication terminal to move in the first cell and the second cell. In this embodiment, the first base station is used as an example for description. The technical solution in this embodiment is mainly used to obtain the central frequency point of the neighboring cell network so as to report it to the OMC.

[0054] Specifically, the method in this embodiment may include the following steps:

[0055] Step 101: Send a terminal handover request on a first base station to a second base station.

[0056] The terminal switching request is used to request to switch the communication terminal from the first cell to the second cell. The communication terminal may be a terminal capable of data communication, such as a mobile phone or a tablet device equipped with a SIM card. Figure 2 As shown in the figure, a user carries a communication terminal and moves from a first cell to a second cell. The communication terminal reports a switching event corresponding to the second cell to the first base station. In response to the switching event, the first base station sends a terminal switching request to the second base station. The second base station obtains the cell configuration information of the second cell in response to the terminal switching request and feeds back to the first base station.

[0057] Step 102: Receive cell configuration information of a second cell fed back by a second base station in response to a handover request of a terminal.

[0058] The cell configuration information at least includes a reference frequency of the second cell. In addition, the cell configuration information may also include other information, such as a subcarrier spacing (subcarrierSpacing) of the second cell, a carrier bandwidth (carrierBandwidth), and a frequency band indicator (FreqBandIndicatorNR) of the second cell.

[0059] Step 103: Obtain the central frequency of the second cell according to the cell configuration information.

[0060] The central frequency of the second cell is used by the first base station to report neighboring cell relationship information. The neighboring cell relationship information may include network information of each second cell adjacent to the first cell, including the central frequency of the second cell. The central frequency of the second cell may be represented by NRCarrierARFCN.

[0061] It can be seen from the above technical solution that in a data processing method provided by an embodiment of the present application, after sending a terminal switching request to the second base station on the first base station, the communication terminal is requested to be switched from the first cell to the second cell, so that the first base station can receive the cell configuration information of the second cell fed back by the second base station in response to the terminal switching request, and the cell configuration information at least includes the reference frequency of the second cell, so that the first base station can obtain the center frequency of the second cell according to the cell configuration information, so that the first base station can report the neighboring cell relationship information according to the center frequency of the second cell. It can be seen that in the present application, when a communication terminal switches the cell network, the base station can use the reference frequency of the neighboring cell fed back by the neighboring cell base station to obtain the center frequency of the neighboring cell network, so that the base station can report the center frequency of the neighboring cell to the OMC, thereby achieving the purpose of the present application.

[0062] In one implementation, this embodiment may also include the following processing: Figure 3 As shown in:

[0063] Step 301: On a first base station, a cell measurement report sent by a communication terminal is received.

[0064] Among them, the communication terminal can report the cell measurement report to the first base station based on the reporting rules of the period or event. The cell measurement report can contain multiple information, such as the public land mobile network PLMN (Public Land Mobile Network), tracking area code TAC (tracking area code), 5G base station global unique identifier gNB ID (globalnodeB identifier), cell ID (cell identity), physical cell identifier PCI (PhysicalCell Identifier), synchronization signal / physical broadcast channel block SSB (Synchronization Signal / PBCH) subcarrier spacing SubcarrierSpacing, etc.

[0065] Step 302: According to the cell measurement report, add the neighbor cell information of the second cell to the neighbor cell list configured by the first base station.

[0066] Among them, the neighboring cell information is used to store the central frequency of the second cell. For example, in this embodiment, according to the cell measurement report, the neighboring cell information such as PLMN, TAC, CellID, PCI and ssbSubcarrierSpacing of the second cell is added to the neighboring cell list of the first base station. In addition, the neighboring cell information can also be used to store the central frequency of the second cell.

[0067] Based on the above implementation, in this embodiment, the first identifier or the second identifier may be set for the second cell according to whether the central frequency point of the second cell is stored in the neighboring cell information.

[0068] The first flag indicates that the first base station is prohibited from reporting the central frequency of the second cell, that is, the first flag indicates that the second cell is a temporary neighboring cell of the first cell, and the first base station cannot report the central frequency of the second cell to the OMC. The second flag indicates that the first base station is allowed to report the central frequency of the second cell, that is, the second flag indicates that the second cell is a formal neighboring cell of the first cell, and the first base station can report the central frequency of the second cell to the OMC.

[0069] Therefore, in this embodiment, after obtaining the central frequency of the second cell according to the cell configuration information, the central frequency of the second cell can be added to the neighboring cell information of the second cell in the neighboring cell list, and then, the second cell in the neighboring cell information is set to correspond to the second identifier, that is, the second cell is set as the formal neighboring cell of the first cell, to indicate that the first base station is allowed to report the central frequency of the second cell.

[0070] In one implementation, in step 103, when obtaining the central frequency of the second cell according to the obtained cell configuration information, it can be implemented in the following manner: Figure 4 As shown in:

[0071] Step 401: Process the reference frequency point according to the first mapping relationship to obtain a reference frequency of the second cell.

[0072] Among them, the first mapping relationship is a mapping relationship between frequency points and frequencies. Specifically, the first mapping relationship can characterize the mapping relationship between the reference frequency point of the second cell and the reference frequency of the second cell regarding at least one configuration information. In addition, the first mapping relationship can characterize the mapping relationship between the center frequency point of the second cell and the center frequency of the second cell regarding at least one configuration information. The configuration information may include: at least one of: frequency offset, frequency point offset, and global frequency grid granularity. Based on this, in this embodiment, the reference frequency point and these configuration information can be processed according to the first mapping relationship to obtain the reference frequency of the second cell.

[0073] In one implementation, in step 401, the frequency offset, frequency point offset and global frequency grid granularity corresponding to the reference frequency point can be queried in the absolute wireless channel number configuration information table of the global frequency grid range in the communication network where the second base station is located, and then the reference frequency point, frequency offset, frequency point offset and global frequency grid granularity are processed according to the first mapping relationship to obtain the reference frequency of the second cell.

[0074] For example, as shown in Table 1, it is an absolute wireless channel number configuration information table about the global frequency grid range, which records the frequency offset corresponding to the frequency range where the reference frequency point is located, the frequency offset, the global frequency grid granularity and the frequency range of the corresponding reference frequency:

[0075] Table 1 Configuration information table

[0076] Frequency range(MHz) <![CDATA[ΔF Global (kHz)]]> <![CDATA[F REF-Offs (kHz)]]> <![CDATA[N REF-Offs ]]> <![CDATA[Range of N REF ]]> 0-3000 5 0 0 0-599999 3000-24250 15 3000 600000 600000-2016666

[0077] Among them, Range of N REF is the frequency range of the reference frequency (center frequency); N REF-Offs is the frequency offset; F REF-Offs is the frequency offset, which is the frequency starting point of the frequency range; ΔF Global is the global frequency grid granularity; Frequency range is the frequency range of the reference frequency (center frequency).

[0078] Based on this, in step 401, based on Table 1, according to the frequency range corresponding to the reference frequency, the corresponding frequency offset F is read in Table 1. REF-Offs , frequency offset N REF-Offs and the global frequency grid granularity ΔF GlobalThen, according to the first mapping relationship represented by formula (1), the reference frequency point and the frequency offset F REF-Offs , frequency offset N REF-Offs and the global frequency grid granularity ΔF Global Processing is performed to obtain the reference frequency of the second cell:

[0079] F REF = F REF-Offs + ΔF Global × (N REF – N REF-Offs ) (1)

[0080] Among them, F in formula (1) REF is the reference frequency of the second cell; N in formula (1) REF is the reference frequency of the second cell.

[0081] Step 402: Obtain the center frequency of the second cell according to the reference frequency.

[0082] Among them, there is a corresponding relationship between the reference frequency of the second cell and the center frequency of the second cell, which can be specifically represented by a second mapping relationship. The second mapping relationship represents a mapping relationship between the reference frequency of the second cell and the center frequency of the second cell regarding at least one communication parameter. In this embodiment, the second mapping relationship can be used to obtain the center frequency corresponding to the reference frequency.

[0083] Specifically, the communication parameters may include at least one of the subcarrier spacing, carrier bandwidth, protection bandwidth and communication bandwidth of the second cell.

[0084] Step 403: Process the center frequency according to the first mapping relationship to obtain the center frequency point of the second cell.

[0085] The mapping relationship between the center frequency point and the center frequency is consistent with the mapping relationship between the reference frequency point and the reference frequency. The first mapping relationship between the center frequency point and the center frequency can be represented by the first mapping relationship shown in formula (2):

[0086] F REF = F REF-Offs + ΔF Global × (N REF – N REF-Offs ) (2)

[0087] Among them, F in formula (2) REF is the center frequency of the second cell; N in formula (2) REF is the central frequency of the second cell.

[0088] Based on this, in this embodiment, the center frequency and corresponding configuration information may be processed according to the first mapping relationship to obtain the center frequency point of the yielded cell.

[0089] In one implementation, in step 403, the frequency offset, frequency point offset and global frequency grid granularity corresponding to the center frequency can be queried in the absolute wireless channel number configuration information table about the global frequency grid range in the communication network where the second base station is located, and then the center frequency, frequency offset, frequency point offset and global frequency grid granularity are processed according to the first mapping relationship to obtain the center frequency point of the second cell.

[0090] For example, as shown in Table 1, in step 403, based on Table 1, according to the frequency range corresponding to the center frequency, the corresponding frequency offset F is read from Table 1. REF-Offs , frequency offset N REF-Offs and the global frequency grid granularity ΔF Global Then, according to the first mapping relationship represented by formula (2), the center frequency and the frequency offset F REF-Offs , frequency offset N REF-Offs and the global frequency grid granularity ΔF Global Processing is performed to obtain the central frequency point of the second cell.

[0091] It can be seen that in this embodiment, the central frequency of the second cell can be obtained through the mapping relationship between the reference frequency, the reference frequency, the central frequency and the central frequency.

[0092] In one implementation, the cell configuration information includes, in addition to the reference frequency of the second cell, the subcarrier spacing and carrier bandwidth of the second cell. Based on this, when obtaining the center frequency of the second cell in step 402, it can be implemented in the following manner, such as Figure 5 As shown in:

[0093] Step 501: Obtain a protection bandwidth of a second cell and a communication bandwidth of the second cell according to the subcarrier spacing and the carrier bandwidth.

[0094] In a specific implementation, when obtaining the protection bandwidth and the communication bandwidth in step 402, they can be obtained by table lookup, that is, by looking up the maximum transmission bandwidth configuration information table and the minimum protection bandwidth configuration information table in the communication network where the second base station is located according to the subcarrier spacing and carrier bandwidth.

[0095] In one implementation, in step 402, the communication bandwidth of the second cell is queried in the maximum transmission bandwidth configuration information table in the communication network where the second base station is located according to the subcarrier spacing and the carrier bandwidth.

[0096] For example, in this embodiment, based on the maximum transmission bandwidth configuration information table shown in Table 2, the communication bandwidth of the second cell can be queried according to the subcarrier spacing and the carrier bandwidth, expressed as BW (bandwidth):

[0097] Table 2 Maximum transmission bandwidth configuration information table

[0098]

[0099] Among them, the numbers in the first row from 5 in the second column to 100 in the last column in Table 2 are in MHz, which is the communication bandwidth BW; the numbers in the third row, fourth row, and fifth row from the second column to the last column in Table 2 are the carrier bandwidth (carrierBandwidth); sCS in the first column in Table 2 is the subcarrier spacing (subcarrierSpacing). Based on this, in this embodiment, the communication bandwidth BW in the first row of Table 2 can be queried based on the subcarrier spacing and the carrier bandwidth.

[0100] In one implementation, in step 402, the protection bandwidth of the second cell is queried in the minimum protection bandwidth configuration information table in the communication network where the second base station is located according to the subcarrier spacing and the communication bandwidth.

[0101] For example, in this embodiment, based on the minimum guard bandwidth configuration information table shown in Table 3, the guard bandwidth of the second cell can be queried according to the subcarrier spacing and the communication bandwidth, expressed in GB (guardband):

[0102] Table 3 Minimum protection bandwidth configuration information table

[0103]

[0104] Among them, in the first row of Table 3, from 5 in the second column to 100 in the last column, the unit of these numbers is MHz, which is the communication bandwidth BW; the numbers from the second column to the last column in the second row, third row and fourth row in Table 3 are the protection bandwidth GB; sCS in the first column of Table 3 is the subcarrier spacing (subcarrier Spacing). Based on this, in this embodiment, the protection bandwidth GW in the second row, third row and fourth row of Table 3 can be queried based on the subcarrier spacing and the communication bandwidth BW. The protection bandwidth refers to the interval bandwidth between the communication bandwidths.

[0105] Step 502: According to the second mapping relationship, the reference frequency, the subcarrier spacing, the protection bandwidth and the communication bandwidth are processed to obtain the center frequency of the second cell.

[0106] The second mapping relationship is a mapping relationship between the reference frequency and the center frequency.

[0107] In a specific implementation, the second mapping relationship can be expressed by formula (3):

[0108] Y = X - SCS*1 / 2–GB + BW*1 / 2 (3)

[0109] Among them, Y is the center frequency, X is the reference frequency, SCS is the subcarrier spacing, GB is the guard bandwidth, and BW is the communication bandwidth.

[0110] Based on this, in this embodiment, the reference frequency, subcarrier spacing, protection bandwidth and communication bandwidth of the second cell are substituted into formula (3) to obtain the center frequency of the second cell.

[0111] It can be seen that in this embodiment, the center frequency of the second cell can be obtained through the mapping relationship between the reference frequency and the center frequency, so as to obtain the center frequency point of the second cell.

[0112] In one implementation, after receiving the cell configuration information of the second cell fed back by the second base station in response to the terminal switching request, this embodiment can also execute a corresponding switching process for the communication terminal according to the cell configuration information.

[0113] Among them, the switching process enables the communication terminal to switch from the first cell to the second cell for communication. That is to say, regardless of whether the central frequency of the second cell can be obtained, the switching process is executed for the communication terminal, so that the communication terminal switches from the first cell to the second cell for communication. It can be seen that in this embodiment, the central frequency of the second cell is obtained according to the cell configuration information corresponding to the terminal switching request, but whether the central frequency is obtained does not affect the communication switching of the communication terminal between communication networks.

[0114] refer to Figure 6 , is a structural diagram of a data processing device provided in an embodiment of the present application, the device can be configured in a base station of a cell network, such as Figure 2 The first base station or the second base station shown, the cell network of the first base station is recorded as the first cell, the cell network of the second base station is recorded as the second cell, and the user carries the communication terminal to move in the first cell and the second cell. In this embodiment, the first base station is used as an example for description. The technical solution in this embodiment is mainly used to obtain the central frequency point of the neighboring cell network so as to report it to the OMC.

[0115] Specifically, the device in this embodiment may include the following units:

[0116] A request sending unit 601 is configured to send a terminal handover request to a second base station on a first base station, where the terminal handover request is used to request handover of a communication terminal from a first cell to a second cell, where the first cell is a cell network of the first base station, and the second cell is a cell network of the second base station;

[0117] The information receiving unit 602 is configured to receive the cell configuration information of the second cell fed back by the second base station in response to the terminal handover request; the cell configuration information at least includes a reference frequency of the second cell;

[0118] The frequency acquisition unit 603 is used to obtain the central frequency of the second cell according to the cell configuration information, and the central frequency of the second cell is used for the first base station to report the neighboring cell relationship information.

[0119] It can be seen from the above technical solution that in a data processing device provided by an embodiment of the present application, after sending a terminal switching request to the second base station on the first base station, the communication terminal is requested to be switched from the first cell to the second cell, so that the first base station can receive the cell configuration information of the second cell fed back by the second base station in response to the terminal switching request, and the cell configuration information at least includes the reference frequency of the second cell, so that the first base station can obtain the center frequency of the second cell according to the cell configuration information, so that the first base station can report the neighboring cell relationship information according to the center frequency of the second cell. It can be seen that in the present application, when a communication terminal switches the cell network, the base station can use the reference frequency of the neighboring cell fed back by the neighboring cell base station to obtain the center frequency of the neighboring cell network, so that the base station can report the center frequency of the neighboring cell to the OMC, thereby achieving the purpose of the present application.

[0120] In one implementation, the device in this embodiment may further include the following units: Figure 7 As shown in:

[0121] The neighbor cell adding unit 604 is used to receive the cell measurement report sent by the communication terminal on the first base station; according to the cell measurement report, add the neighbor cell information of the second cell to the neighbor cell list configured by the first base station; wherein the neighbor cell information is used to store the central frequency point of the second cell.

[0122] Furthermore, the neighboring cell adding unit 604 is also used to: set a first identifier or a second identifier for the second cell according to whether the central frequency of the second cell is stored in the neighboring cell information; wherein the first identifier indicates that the first base station is prohibited from reporting the central frequency of the second cell; and the second identifier indicates that the first base station is allowed to report the central frequency of the second cell.

[0123] Among them, the neighboring cell adding unit 604 is also used to: after the frequency acquisition unit 603 obtains the central frequency of the second cell according to the cell configuration information, add the central frequency of the second cell to the neighboring cell information of the second cell in the neighboring cell list; set the second cell in the neighboring cell information to correspond to the second identifier.

[0124] In one implementation, the frequency point acquisition unit 603 is specifically used to: process the reference frequency point according to a first mapping relationship to obtain a reference frequency of the second cell; the first mapping relationship is a mapping relationship between frequency points and frequencies; obtain the center frequency of the second cell according to the reference frequency; process the center frequency according to the first mapping relationship to obtain the center frequency point of the second cell.

[0126] Specifically, when the frequency point acquisition unit 603 obtains the protection bandwidth of the second cell and the communication bandwidth of the second cell according to the subcarrier spacing and the carrier bandwidth, it is specifically used to: in the maximum transmission bandwidth configuration information table in the communication network where the second base station is located, query the communication bandwidth of the second cell according to the subcarrier spacing and the carrier bandwidth; in the minimum protection bandwidth configuration information table in the communication network where the second base station is located, query the protection bandwidth of the second cell according to the subcarrier spacing and the communication bandwidth.

[0128] In one implementation, the device in this embodiment may further include the following units: Figure 8 As shown in:

[0129] The communication switching unit 605 is used to execute a corresponding switching process for the communication terminal according to the cell configuration information after the information receiving unit 602 receives the cell configuration information of the second cell fed back by the second base station in response to the terminal switching request; wherein the switching process enables the communication terminal to switch from the first cell to the second cell for communication.

[0130] It should be noted that the specific implementation method of each unit in this embodiment can refer to the corresponding content in the previous text and will not be described in detail here.

[0131] refer to Fig. 9 , is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application, the electronic device can be deployed in Figure 2 The first base station shown, the electronic device may include the following structure:

[0132] Communication module 901 and processor 902, wherein:

[0133] The communication module 901 is used to send a terminal handover request to a second base station, where the terminal handover request is used to request to handover a communication terminal from a first cell to a second cell, where the first cell is a cell network of the first base station, and the second cell is a cell network of the second base station;

[0134] The communication module 901 is further configured to receive cell configuration information of the second cell fed back by the second base station in response to the terminal handover request; the cell configuration information at least includes a reference frequency of the second cell;

[0135] The processor 902 is used to obtain a central frequency of the second cell according to the cell configuration information, where the central frequency of the second cell is used by the first base station to report neighboring cell relationship information.

[0136] It can be seen from the above technical solution that in an electronic device provided by an embodiment of the present application, after sending a terminal switching request to the second base station on the first base station, the communication terminal is requested to be switched from the first cell to the second cell, so that the first base station can receive the cell configuration information of the second cell fed back by the second base station in response to the terminal switching request, and the cell configuration information at least includes the reference frequency of the second cell, so that the first base station can obtain the center frequency of the second cell according to the cell configuration information, so that the first base station can report the neighboring cell relationship information according to the center frequency of the second cell. It can be seen that in the present application, when a communication terminal switches the cell network, the base station can use the reference frequency of the neighboring cell fed back by the neighboring cell base station to obtain the center frequency of the neighboring cell network, so that the base station can report the center frequency of the neighboring cell to the OMC, thereby achieving the purpose of the present application.

[0137] Taking a 4G communication network or a 5G communication network as an example, the technical solution of the present application is described below:

[0138] The function of automatic neighbor relationship ANR (Automatic Neighbor Relationship) pays attention to the relationship between neighboring cells in 4G / 5G networks, and can be set automatically, replacing the tedious steps of manually configuring neighbor relationships. The neighbor relationship configured by the base station cell, whether it is manually configured or automatically configured by ANR, needs to be reported to the OMC network management system. The base station obtains the cell information of the neighboring cell by configuring the cell measurement report (ReportType: reportCGI) for the terminal accessing this network, thereby realizing the automatic addition of neighbor relationships.

[0139] In the 5G small base station communication operator specifications, "5G Neighborhood Cell Parameter Management" clearly defines that the center frequency parameter "NRCarrierARFCN" must be reported to the network management as one of the 5G neighbor cell parameters, and defines the data model specification for the parameter.

[0140] Device.Services.FAPService.{i}.CellConfig.{i}.NR.RAN.NeighborList.NRCell.{i}.NRCarrierARFCN

[0141] The NRCarrierARFCN (NRARFCN) parameter indicates the system center frequency of the cell configuration (also called the center frequency number). The center frequency of the cell configuration can be calculated through the cell center frequency, and similarly, the center frequency can also be calculated inversely through the center frequency.

[0142] However, the CGI-info information element specified in the 3GPP protocol does not contain information about the center frequency. In addition, in the 5G system, the communication terminal uses the SSB (Sync Signal Block) frequency to perform cell / neighboring cell measurements, and does not directly use the 5G cell center frequency. Therefore, the ANR function also uses the corresponding SSB frequency when configuring the measurement. In this way, when the 5G base station automatically adds neighboring cell relationships through ANR, it cannot directly obtain the neighboring cell center frequency information, and cannot report complete neighboring cell information according to the operator's data model requirements. The above problems belong to the requirements of the operator's specifications for base station equipment manufacturers, but the existing protocol specifications for the ANR function cannot fully meet the scenario.

[0143] In view of this, this application introduces the definition of "temporary neighboring cell" to obtain neighboring cell information (i.e., the cell configuration information in the previous article) during the actual communication switching phase. The information of the neighboring cell center frequency point can be obtained by calculation, thereby supplementing the neighboring cell center frequency point information added by ANR to meet the operator's specification requirements.

[0144] The following is a description of the technical highlights of this application:

[0145] 1. After the ANR function of the base station is enabled, after receiving the cell measurement report (including CGI-info) reported by the communication terminal UE (User Equipment), the corresponding inter-frequency cell information is extracted, and the corresponding neighboring cell information is automatically added to the neighboring cell list according to the normal process, but the corresponding correct NRCarrierARFCN information is not included;

[0146] 2. The added neighboring cell is marked as a "temporary neighboring cell". The base station can perform related handovers, but the base station's operation, maintenance and management (OAM) module does not perform formal neighboring cell processing.

[0147] 3. After the UE reports the switching event of the corresponding neighboring cell for the second time, the switching is performed according to the normal process, and the configuration information related to the target neighboring cell frequency is extracted. The NRCarrierARFCN information of the target cell (i.e. the second cell in the previous article) is obtained by calculation, and then updated to the "temporary neighboring cell" information to complete the formal ANR neighboring cell automatic configuration.

[0148] Based on this, by adopting the technical solution of this application, the automatic acquisition of neighboring NRCarrier ARFCN information can be achieved through program calculation, reducing the manual input steps; moreover, this application utilizes the existing process of the protocol, while meeting the operator's specification requirements and not introducing other non-standard processes.

[0149] refer to Fig.10 The specific implementation scheme of the processing flow shown is as follows:

[0150] First, the ANR-related measurements (NR Freq) of the base station are pre-configured. Based on this, the UE performs relevant neighboring cell measurements. After the UE reports the cell measurement report (A event) of the ANR-related configuration based on the periodic or event-based reporting rules, the base station determines whether the reported cell has a formal neighboring cell relationship. If so, the switching is performed normally without entering the solution process of this application.

[0151] If the neighboring cell relationship (including the above-mentioned "temporary neighboring cell") does not exist, the ReportCGI reconfiguration message corresponding to the reporting cell (PCI) is configured to the UE.

[0152] Then, the UE measures the information of the target cell. After the UE uploads the CGI-information (i.e., cell measurement report CGI-info) of the corresponding cell, the base station extracts the neighboring cell information of the cell: PLMN, TAC, gNB ID, Cell ID, PCI, ssbSubcarrierSpacing, etc., and marks the cell as a "temporary neighboring cell" (i.e., the first identifier in the previous text), notifies OAM to update the neighboring cell list, and synchronously marks it as a "temporary neighboring cell". The "temporary neighboring cell" does not obtain the correct neighboring cell center frequency information, and OAM does not synchronize OMC as a formal neighboring cell, but the base station uses it as a normal neighboring cell when switching.

[0153] Among them, in OMC, the neighboring cell is added to the "temporary neighboring cell list", and the temporary neighboring cell has no NR-ARFCN (the temporary neighboring cell is not reported to OMC).

[0154] When the UE reports the configured mobility measurement report for the second time (i.e., handover event A), the base station determines whether the corresponding cell (PCI / SSB Freq) already has a neighboring cell relationship. If so, it determines whether it is a marked "temporary neighboring cell". If not, it is a formal neighboring cell and can be switched normally. If so, after initiating a handover request, it obtains the neighboring cell reply message, executes the handover, and extracts the necessary information in the handover Acknowledge (i.e., cell configuration information) to calculate the central frequency of the opposite target cell. The information obtained is as follows:

[0155] a. FreqBandIndicatorNR target cell frequency band indication;

[0156] b. absoluteFrequencyPointA: the absolute frequency point PointA of the target cell, i.e. the reference frequency point;

[0157] c. subcarrierSpacing target cell subcarrier spacing;

[0158] d. carrierBandwidth: target cell carrier bandwidth (ie, PRB size).

[0159] Based on this, through the information obtained, combined with the relevant tables of the 3GPP protocol on ARFCN definition, such as Table 1 to Table 3, the target cell center frequency can be calculated; the target cell NRCarrier ARFCN can be converted through the frequency information.

[0160] While obtaining the above information and calculating, the base station continues the UE's switching process normally; at the same time, the obtained NRCarrierARFCN information is updated to the corresponding neighboring cell information in the neighboring cell list, and the historical mark is cancelled, and the neighboring cell status is updated to the formal neighboring cell (that is, the second mark in the previous text), and the OAM module is notified to report the OMC neighboring cell update information.

[0161] The following is a method and example for calculating the target cell center frequency:

[0162] 1) The frequency and NR-ARFCN conversion formulas are shown in formulas (1) and (2). REF It is NR-ARFCN. By looking up Table 1 in protocol 38.101-1, we can know the calculated values ​​of different frequency ranges. The relevant parameters can be obtained through the reference frequency point "absoluteFrequencyPointA" and converted into the reference frequency.

[0163] 2) At the same time, by using the subcarrier spacing subcarrierSpacing and the carrier bandwidth carrierBandwidth, that is, the number of RBs, the protection bandwidth GB and the communication bandwidth BW of the target cell can be obtained by looking up Table 2 and Table 3.

[0164] Based on this, according to formula (3), the center frequency calculated based on the reference frequency can be converted to obtain the center frequency point.

[0165] Taking absoluteFrequencyPointA as 503172 as an example, the following algorithm is used to obtain information from the target cell handover Acknowledge message and calculate the center frequency NR ARFCN:

[0166] First, the reference frequency absoluteFrequencyPointA is 503172. From Table 1, we can see that it belongs to the frequency range of 0-3000Mhz. According to the above formula (1), the reference frequency Frequency is 503172×0.005, that is, 2515.86Mhz.

[0167] Then, according to formula (3) in the previous article, the center frequency Frequency is calculated as: 2515.86 -0.015×(SCS×1 / 2)-0.845×(GB)+50×(BW×1 / 2), which is 2565MHz;

[0168] Finally, according to formula (2) in the previous article, the center frequency NR ARFCN is calculated as: 2565 / 0.005, which is 513000, which is NRCarrierARFCN.
