Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the present invention. The terms used herein in the description of the present invention are for the purpose of describing particular embodiments only, and are not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in Figure 1 is a schematic diagram of the architecture of the 5G communication system. 5GC represents the core network. Before accessing the network, UE (User Equipment, user terminal) must first obtain the system information broadcast by the network, so as to know the configuration parameters of the network. Take the proper way to start your business. System information is broadcast to all UEs within the cell range by RRC (Radio Resource Control, Radio Resource Management) in the RAN (Radio Access Network, Radio Access Network) to notify the UE of the network access layer and non-access layer. public information. Multiple cells can be opened under one base station, and the system information of each cell can be different. Therefore, each cell needs to broadcast a set of independent system information. In the 5G NR (New Radio) system, the main contents of system information and its broadcast are shown in Table 1 below:

Table 1

type content MIB Basic information for receiving other system information, cell access barring status information SIB1 Scheduling information and initial access request information of other SIBs SIB2 Cell reselection information related to the serving cell SIB3 Service frequency information, cell reselection information of the same-frequency neighbor cell SIB4 Frequency points of NR, reselection information of inter-frequency neighbor cells

Table 1 (continued)

SIB5 Frequency points of E-UTRA, reselection information of E-UTRA neighboring cells SIB6 ETWS main notification information SIB7 ETWS Minor Notification Information SIB8 CMAS Warning Notification Information SIB9 GPS time related information, general time adjustment information

The parameters of the system information MIB and SIB1 are configured by the DU, and the parameters of other system information SIB2 to SIB9 are configured by the CU. When the system information MIB and SIB1 of the DU are changed, the DU needs to send all the system information after the change to the CU. The CU will configure and save the new system information MIB and SIB1 parameters. Correspondingly, when the system information SIB2 to SIB9 of the CU changes, it also needs to be sent to the DU. The DU will configure and save the parameters of the new system information SIB2 to SIB9 and forward them to the UE. The UE learns that the system information has changed by receiving the Short Message (short message) sent by the cell where it is located.

The above-mentioned Short Message is indicated by DCI (Downlink Control Information, downlink control information) scrambled by P-RNTI (Paging Radio Network Tempory Identity, paging radio network temporary identifier). The Short Message contains the SI modifications (system information modification) field and the PWSnotifications (public early warning system notification) field. When the UE successfully receives the Short Message, the UE can know that the system information will change in the next broadcast cycle. When the UE is in the RRC_IDLE (RRC idle mode) and RRC_INACTIVE (RRC connection inactive) states, it will monitor each paging opportunity in the DRX cycle (Discontinuous Reception cycle, discontinuous reception cycle); in the RRC_CONNECTED (RRC connection) state, each paging opportunity Monitor at least one paging opportunity during the change period.

Aiming at the low efficiency problem existing in the update processing method in the traditional 5G NR system, the update processing method of the system information provided in this application can be applied to the application environment as shown in FIG. 1 . In the 5G NR system, when the CU system information (ie, system information SIB2 to SIB9) configured by the CU is updated, the CU marks the updated CU system information, and generates a corresponding CU configuration update message. Further, the CU sends the aforementioned CU configuration update message to the DU, so that after receiving the CU configuration update message, the DU updates the CU system information marked in the CU configuration update message. In this way, the marked old CU system information in the DU is correspondingly updated to the marked latest CU system information.

Referring to FIG. 2 , in one embodiment, from the perspective of taking the CU as the execution subject, a method for updating system information is provided. Taking the application environment shown in FIG. 1 as an example, the method includes the following steps S12 and S14:

S12, when the CU system information is updated, mark the updated CU system information, and generate a corresponding CU configuration update message.

It can be understood that the CU system information refers to any one of the system information SIB2 to SIB9 configured by the CU. The update of the CU system information can be caused by manually configuring any one or more of the new system information SIB2 to SIB9, or it can be the CU itself or the 5G core network according to the pre-stored system information parameter table. Automatically indicates that the system information is changed.

The marker refers to a feature added to the CU system information indicating that the CU system information has been changed, so that the DU can directly determine which or several CU system information has changed through the marker. The mark may be a numerical symbol, a letter, or a symbol in other forms, as long as it can indicate to the DU that the system information of the CU to which it belongs has changed. The CU configuration update message also refers to the configuration message (CU CONFIGURATION UPDATE) sent by the CU to the DU after each system information change occurs. Corresponding system information update processing.

Specifically, in the CU, when any one or more CU system information is changed (also called an update), the CU marks the changed CU system information, and accordingly generates a CU configuration required to notify the DU to update the system information. Update message. For example, when the CU obtains the new system information SIB2 (other system information can be understood in the same way), and replaces the original saved old system information SIB2 with the new system information SIB2, the CU performs the new system information SIB2 mark; after the mark is completed, a CU configuration update message can be correspondingly generated.

S14: Send a CU configuration update message to the DU, where the CU configuration update message is used to instruct the DU to update the marked CU system information.

It can be understood that after the CU system information is updated on the CU, the CU system information stored in the CU will be different from the corresponding CU system information stored in the DU. Therefore, the CU can send the generated CU configuration update message to the DU through the F1 interface, so that after receiving the CU configuration update message, the DU performs update processing according to the CU system information marked in the CU configuration update message. That is, the corresponding CU system information that was originally stored is updated with the CU system information that has been updated, so that the CU system information stored in the DU is kept consistent with the CU system information stored in the CU.

Taking the system information SIB5 and the above-mentioned system information SIB2 as an example, after the CU sends the corresponding CU configuration update message to the DU, the DU will make the DU according to the marked system information SIB5 and system information SIB2 in the CU configuration update message, to the original DU. The saved old system information SIB5 and system information SIB2 are updated. There is no need to update other unmarked system information, so that the system information of each CU saved in the DU is consistent with the system information of each CU currently saved by the CU.

In the above-mentioned system information update processing method, when the CU system information is updated, the CU marks the updated system information, and then generates a corresponding CU configuration update message and sends it to the DU. After the DU receives the CU configuration update message, it only needs to update the marked CU system information, and the CU system information that is not marked remains unchanged. In this way, the DU does not need to update all the CU system information of the CU every time, which can effectively reduce the number of system information updates, help to reduce the signaling interaction within the base station (GNB), achieve the purpose of greatly improving the efficiency of system information update, save power and system resource.

Referring to FIG. 3, in one embodiment, the process of marking the updated CU system information in the above step S12 may include the following processing step S122:

S122: Set the value of the CU system information change indication corresponding to the updated CU system information as a first setting identifier; the first setting identifier is used to indicate the updated CU system information to the DU.

It can be understood that the CU system information change indication refers to a newly added auxiliary IE (information element, information element) in the CU configuration update message, which is used to identify each CU system information respectively. The auxiliary IE may be, but is not limited to, an array-type IE. For example, an auxiliary IE list (ie, CU SystemInformation Change Indicator List, CU system information change indication table) is added to the CU configuration update message, including CU system information change indications corresponding to each CU system information one-to-one. In this way, the value of the CU system information change indication is set to represent whether the corresponding CU system information is changed.

The first setting identifier may be a numerical identifier (such as 0 or 1), an alphabetical identifier (such as Change or C, etc.), or other forms of symbols, which are used to represent that the corresponding CU system information has changed and is a newly configured CU system message. Specifically, the auxiliary IE configured in the CU configuration update message of the CU may be pre-configured to create corresponding indication parameters for each CU system information. When any CU system information in the CU is updated, the CU can set the value of the CU system information change indication corresponding to the updated CU system information in the auxiliary IE list to the first setting identifier to mark the CU The system information is the system information for which an update occurs.

Taking the system information SIB2 (which can be understood in the same way for other system information) as an example, when the CU obtains the new system information SIB2 and replaces the original saved old system information SIB2 with the new system information SIB2, it can correspondingly The value of the CU system information change indication corresponding to the system information SIB2 is set as Change to mark that the system information SIB2 is updated. In this way, the CU configuration update message generated by the CU and sent to the DU through the F1 interface will include the new system information SIB2 and the CU system information change indication whose value is Change corresponding to the new system information SIB2. After the DU receives the CU configuration update message, the DU can determine whether the corresponding CU system information is updated by judging whether the value of the CU system information change indication corresponding to each CU system information is Change. Therefore, after receiving the CU configuration update message, the DU can determine that the value of the CU system information change indication corresponding to the system information SIB2 is Change, and update the old system information SIB2 saved by itself with the new system information SIB2.

Through the above step S122, the CU can efficiently mark the updated CU system information, so that the DU can efficiently complete the CU according to whether the value of the CU system information change indication corresponding to the CU system information is the first setting identifier. The determination of whether the system information has been updated can speed up the determination of the updated CU system information and its update processing.

In one embodiment, as shown in FIG. 3, before the corresponding CU configuration update message is generated in the above step S12, the following processing step S124 may also be included:

S124: Set the value of the CU system information change indication corresponding to the CU system information that has not been updated as a second setting identifier; the second setting identifier is used to indicate the CU system information that has not been updated to the DU.

It can be understood that the second setting identifier may be a numerical identifier (for example, 1 or 0), an alphabetical identifier (for example, UnChange or UnC, etc.), or other forms of symbols, which are used to represent that the corresponding CU system information has not changed, and it is not necessary to carry out renew. Before the value of the CU system information change indication corresponding to the updated CU system information for the CU is the first setting identifier, the value of the CU system information change indication corresponding to each CU system information may be null or a default value, to indicate that the existing system information of each CU has not been updated. The marking of DU system information occurring in the following DU can be similarly understood. In this way, when the CU system information is updated, the CU can modify the value of the CU system information change indication corresponding to the updated CU system information from the default value to the first setting identifier to mark the updated CU system information .

Specifically, when the CU sets the value of the CU system information change indication corresponding to the updated CU system information as the first setting identifier, the CU may also indicate other CU system information that has not been updated, that is, set other unupdated CU system information. The value of the CU system information change indication corresponding to the updated CU system information is the second setting identifier. In this way, when the DU performs the CU system information update process, it can directly determine whether each corresponding CU system information is the CU system information that has not been updated by judging whether the value of the CU system information change indication is the second setting identifier.

Taking the system information SIB2 (which can be understood in the same way for other system information) as an example, when the CU sets the value of the CU system information change indication corresponding to the updated system information SIB2 to Change, it can also set other CU systems that have not been updated. The values of each CU system information change indication corresponding to the information are respectively set as the second setting identifier, for example, set as UnChange. In this way, the CU configuration update message generated by the CU and sent to the DU through the F1 interface will include the new system information SIB2, the CU system information change indication with the value of Change corresponding to the new system information SIB2, and other unupdated information. The value corresponding to the CU system information of the CU system information is a change indication of each CU system information of UnChange.

After the DU receives the CU configuration update message, it will enable the DU to determine whether the corresponding CU system information has been updated or not by judging whether the value of the CU system information change indication corresponding to each CU system information is Change or UnChange. . Therefore, after receiving the CU configuration update message, the DU can determine that the values of the CU system information change indications corresponding to the system information SIB3 to the system information SIB9 are UnChange, and do not update the saved system information SIB3 to the system information SIB9. , that is, keep the saved system information SIB3 to system information SIB9 unchanged.

Through the above step S124, the CU can efficiently process the indication of the CU system information that has not been updated, so that the DU can efficiently determine whether the value of the CU system information change instruction corresponding to the CU system information is the second setting identifier. The determination of whether the CU system information has not been updated is completed, and the determination of the CU system information that has not been updated is accelerated.

Referring to FIG. 4 , in one embodiment, the above-mentioned method for updating system information may further include the following processing steps S16 and S18:

S16: Receive a DU configuration update message sent by the DU.

The DU configuration update message refers to the configuration message (DU CONFIGURATION UPDATE) sent by the DU to the CU after each change of the DU system information. to notify the CU to perform corresponding DU system information update processing. The DU system information refers to any one of the system information MIB and SIB1 configured by the DU. The update of the DU system information can also be caused by the manual configuration of any one or both of the new system information MIB and SIB1, or the DU itself or the 5G core network according to the pre-stored system information parameter table, The timing automatically indicates that the system information is changed.

It can be understood that in the DU, when the DU system information is changed (also called an update), the DU marks the changed DU system information, and accordingly generates a DU configuration update message required to notify the CU to update the system information. For example, when the DU replaces the old system information SIB1 saved with the new system information SIB1 because it obtains the new system information SIB1 (the system information MIB can be understood in the same way), the DU is the new system information SIB1 Mark; after marking is completed, a DU configuration update message can be generated correspondingly.

Specifically, when the DU system information on the DU is updated, it also needs to be sent to the CU for updating. Therefore, when the DU system information on the DU is updated, the CU will receive the DU configuration update message sent by the DU through the F1 interface.

S18: Determine the marked DU system information in the DU configuration update message, and update the marked DU system information.

It can be understood that after the CU receives the DU configuration update message, it can update its own DU system information according to the DU system information marked in the DU configuration update message. That is, the marked DU system information is used to update the original stored corresponding DU system information, so that the system DU system information stored in the CU is kept consistent with the DU system information stored in the DU.

Taking the system information SIB1 as an example, after the CU receives the corresponding DU configuration update message, the CU will update the old system information SIB1 originally saved by the CU according to the system information SIB1 marked in the DU configuration update message. There is no need to update the unmarked system information MIB, so that the system information of each DU stored in the CU is consistent with the system information of each DU currently stored in the DU.

Through the above processing steps S16 and S18, when the CU receives the DU configuration update message sent by the DU, the CU only needs to update the marked DU system information, and the unmarked DU system information may remain unchanged. In this way, the CU does not need to update all the DU system information of the DU every time, which can further effectively reduce the number of system information updates, and is more conducive to reducing the signaling interaction within the base station (GNB), so as to further improve the efficiency of system information update.

Referring to FIG. 5 , in one embodiment, the process of determining the DU system information marked in the DU configuration update message in the above step S18 may specifically include the following implementation of step S182:

S182, in the DU configuration update message, check the value of the DU system information change indication corresponding to each DU system information.

It can be understood that the DU system information change indication refers to a newly added auxiliary IE in the DU configuration update message, which is used to identify the system information of each DU respectively. The auxiliary IE may be, but is not limited to, an array-type IE. For example, an auxiliary IE list (ie, DU System Information Change Indicator List, DU system information change indicator list) is added to the DU configuration update message, which includes DU system information change indicators corresponding to each DU system information one-to-one. Therefore, whether the corresponding DU system information is changed can be represented by setting the value of the DU system information change indication.

Specifically, after receiving the DU configuration update message sent by the DU through the F1 interface, the CU can judge each DU system by checking the value of the DU system information change indication of all DU system information contained in the DU configuration update message. Whether the information has changed, in order to determine whether the corresponding DU system information needs to be updated.

S184, if the value of the DU system information change indication is the first setting identifier, determine that the DU system information corresponding to the first setting identifier is the marked DU system information; the first setting identifier is used to indicate each DU system of the DU The updated DU system information occurs in the message.

Wherein, the first setting identifier can be understood in the same way with reference to the above-mentioned embodiment about the CU system information change indication, and details are not repeated here. Specifically, the DU can also mark the updated DU system information by creating a corresponding indication parameter for each DU system information through the auxiliary IE configured in the DU configuration update message in advance. When any DU system information in the DU is updated, the DU can set the value of the DU system information change indication corresponding to the updated DU system information in the auxiliary IE list to the first setting identifier to mark the DU The system information is the system information for which an update occurs.

Taking the system information SIB1 (the system information MIB can be understood in the same way) as an example, when the DU obtains the new system information SIB1 and replaces the original saved old system information SIB1 with the new system information SIB1, it can correspondingly The value of the DU system information change indication corresponding to the system information SIB1 is set to Change to mark that the system information SIB1 is updated. In this way, the DU configuration update message generated by the DU and sent to the CU through the F1 interface will include the new system information SIB1 and the DU system information change indication whose value is Change corresponding to the new system information SIB1. After the CU receives the DU configuration update message, it can determine whether the corresponding DU system information is updated by judging whether the value of the DU system information change indication corresponding to each DU system information is Change, that is, whether it is marked. DU system information. In this way, after receiving the DU configuration update message, the CU can quickly update the old system information SIB1 saved by itself with the new system information SIB1 after judging that the value of the DU system information change indication corresponding to the system information SIB1 is Change.

Through the above steps S182 and S184, the CU can efficiently complete the judgment of whether the DU system information has been updated by checking whether the value of the DU system information change indication corresponding to the DU system information is the first setting identifier, and speed up the update of the DU. The system information is determined to improve the processing efficiency of updating the DU system information.

In one embodiment, as shown in FIG. 5, after the above-mentioned step S18, the following processing step S19 may also be included:

S19, reply to the DU with a DU configuration update confirmation message.

The DU configuration update confirmation message is the confirmation message (that is, the GNB-DU CONFIGURATION UPDATEACKNOWLEDGE message) that is sent to the DU after the CU completes the update processing of the DU system information stored by itself according to the received DU configuration update message. Notifies the DU that the DU system information update is currently completed.

Specifically, after the CU completes the DU system information update process, it can also reply a DU configuration update confirmation message to the DU, so that after the DU receives the DU configuration update confirmation message, it can know that the DU system information currently stored on the CU has been completed. It is updated and consistent with the DU system information saved by the DU itself. Through the above step S19, the CU can quickly notify the DU after completing the DU system information update process, so as to realize the synchronization of the update state of the system information between the CU and the DU.

Referring to FIG. 6, in one embodiment, from the perspective of taking the DU as the execution subject, another method for updating system information is provided. Taking the application environment shown in FIG. 1 as an example, the method includes the following processing: Steps S21 and S23:

S21, receive the CU configuration update message sent by the CU;

S23: Determine the marked CU system information in the CU configuration update message, and update the marked CU system information.

For the explanation of technical terms such as the CU configuration update message, CU system information, and marked CU system information in this embodiment, reference may be made to the above-mentioned update processing method for system information from the perspective of the CU as the execution subject. In each corresponding embodiment of the above, the explanation of technical terms such as the CU configuration update message, the CU system information, and the marked CU system information will not be repeated here.

Specifically, after the DU receives the CU configuration update message sent by the CU through the F1 interface, the DU performs update processing according to the CU system information marked in the CU configuration update message. That is, check whether each CU system information is marked in the CU configuration update message, and then update the marked CU system information, such as using the updated (that is, marked) CU system information to update the original saved corresponding information. CU system information, so that the CU system information currently saved by the DU itself remains consistent with the CU system information currently saved in the CU.

Taking system information SIB5 and system information SIB2 as an example, when the DU receives the corresponding CU configuration update message sent by the CU, the DU will save the system information SIB5 and system information SIB2 marked in the CU configuration update message to the DU itself. The old system information SIB5 and system information SIB2 are updated. There is no need to update other unmarked CU system information (such as system information SIB3, system information SIB4, system information SIB6, system information SIB7, system information SIB8 and system information SIB9), so as to realize the system information of each CU currently stored in the DU. It is consistent with the system information of each CU currently saved by the CU.

In the system information update processing method in this embodiment, after receiving the CU configuration update message sent by the CU, the DU only needs to update the marked CU system information, and the unmarked CU system information remains unchanged. . In this way, the DU does not need to update all CU system information every time, which can effectively reduce the number of system information updates, help reduce the signaling interaction within the base station (GNB), achieve the purpose of greatly improving the efficiency of system information update, and save power and system. resource.

Referring to FIG. 7, in one embodiment, regarding the above-mentioned step S23, the process of determining the CU system information marked in the CU configuration update message may specifically include the following processing steps S232 and S234:

S232, in the CU configuration update message, check the value of the CU system information change indication corresponding to each CU system information respectively.

For the explanation of the value of the CU system information change indication, please refer to the explanation about the CU system information change indication in the corresponding embodiment of the system information update processing method provided above from the perspective of the CU as the execution subject, It will not be repeated here. From the perspective of the above-mentioned CU as the execution subject, the same technology in the corresponding embodiment of the method for updating the system information provided in the following description can also be understood with reference to the same.

Specifically, after receiving the CU configuration update message sent by the CU through the F1 interface, the DU can judge each CU system by checking the value of the CU system information change indication of all CU system information contained in the CU configuration update message. Whether the information has changed, so as to determine whether the corresponding CU system information needs to be updated.

S234, if the value of the CU system information change indication is the first setting identifier, determine that the CU system information corresponding to the first setting identifier is the marked CU system information; the first setting identifier is used to indicate each CU system of the CU The CU system information where the update occurred in the message.

Specifically, when the DU determines in the CU configuration update message that the value of any CU system information change indication is the first setting identifier, the DU can determine the CU system information corresponding to any CU system information change indication, It is the marked CU system information, that is, the CU system information that needs to be updated.

Taking the system information SIB2 (the system information SIB3 to the system information SIB9 can be understood in the same way) as an example, when the DU receives the CU configuration update message, it can judge whether the value of the CU system information change indication corresponding to each CU system information is Change, to determine whether the corresponding CU system information is updated, that is, whether it is the marked CU system information. In this way, after receiving the CU configuration update message, the DU can quickly update the old system information SIB2 saved by itself with the new system information SIB2 after judging that the value of the CU system information change indication corresponding to the system information SIB2 is Change.

Through the above steps S232 and S234, the DU can efficiently complete the judgment of whether the CU system information has been updated by checking whether the value of the CU system information change indication corresponding to the CU system information is the first setting identifier, and speed up the CU system information update. The system information is determined to improve the update processing efficiency of the CU system information.

Referring to FIG. 8, in one embodiment, the above-mentioned another method for processing system information update may further include the following processing steps S25 and S27:

S25, when the DU system information is updated, mark the updated DU system information, and generate a corresponding DU configuration update message;

S27: Send a DU configuration update message to the CU, where the DU configuration update message is used to instruct the CU to update the marked DU system information.

It can be understood that in the DU, when the DU system information (that is, the system information MIB and the system information SIB1) configured by the DU itself is changed (also called an update), the DU will mark the changed DU system information and generate a corresponding notification. The DU configuration update message required by the CU to perform system information update. For example, when the DU replaces the old system information SIB1 saved with the new system information SIB1 because it obtains the new system information SIB1 (the system information MIB can be understood in the same way), the DU will perform the operation on the new system information SIB1. mark; after the mark is completed, the DU configuration update message can be correspondingly generated.

The DU can send the generated DU configuration update message to the CU through the F1 interface, so that after the CU receives the DU configuration update message, it performs update processing according to the DU system information marked in the DU configuration update message, so that the CU is updated. The stored DU system information remains consistent with the DU system information stored in the DU.

Through the above processing steps S25 and S27, the DU sends a DU configuration update message to the CU, so that the CU only needs to update the marked DU system information, and the unmarked DU system information remains unchanged. In this way, the CU does not need to update all the DU system information of the DU every time, which can further effectively reduce the number of system information updates, and is more conducive to reducing the signaling interaction within the base station (GNB), so as to further improve the efficiency of system information update.

In one embodiment, the process of marking the updated DU system information in the above processing step S25 may specifically include the following processing steps:

The value of the DU system information change indication corresponding to the updated DU system information is set as the first setting identifier; the first setting identifier is used to indicate the updated DU system information to the CU.

The value of the DU system information change indication corresponding to the updated DU system information is the second setting identifier. In this way, when the CU performs the DU system information update process, it can directly determine whether each corresponding DU system information is the DU system information that has not been updated by checking whether the value of the DU system information change indication is the second setting identifier.

Taking the system information SIB1 (the same can be understood for the system information MIB) as an example, when the DU sets the value of the DU system information change indication corresponding to the updated system information SIB1 to Change, other DU systems that have not been updated can also be changed. The values of each DU system information change indication corresponding to the information are respectively set as the second setting identifier, for example, set as UnChange. In this way, the DU configuration update message generated by the DU and sent to the CU through the F1 interface will include the new system information SIB1, the DU system information change indication with the value of Change corresponding to the new system information SIB1, and other unupdated information. The corresponding value of the DU system information is UnChange each DU system information change indication.

After the CU receives the DU configuration update message, it will enable the CU to determine whether the corresponding DU system information has been updated or not by judging whether the value of the DU system information change indication corresponding to each DU system information is Change or UnChange. . Therefore, after receiving the DU configuration update message, the CU can determine that the value of the DU system information change indication corresponding to the system information MIB is UnChange, and then does not update the saved system information MIB, that is, keeps the saved system information. MIBs are unchanged.

Through the above steps, the DU can efficiently implement the indication processing of the DU system information that has not been updated, so that the CU can efficiently complete the process by judging whether the value of the DU system information change indication corresponding to the DU system information is the second setting identifier. The determination of whether the DU system information has not been updated can speed up the determination of the DU system information that has not been updated.
