Switching method and equipment

[0189] Example 1:

[0190] like Figure 5 As shown, a schematic flowchart of a complete method for switching a DU between CUs provided by an embodiment of the present application.

[0191] Step 501: The source CU determines to switch a certain DU under its jurisdiction to the target CU.

[0192] The triggering condition of the handover can be any condition such as time-based, location-based, RRM measurement-based, or CU or DU load information.

[0193] Step 502: The source CU sends an inter CU handover request message to the DU.

[0194] The message may carry some or all of the following information: ID (gNB ID) of the target CU, name (name) of the target CU, TNL address of the target CU, and OAM configuration information of the DU.

[0195] It should be noted that the OAM configuration information of the DU here may include configuration information such as the frequency, PCI, and CGI of the DU when it is connected to the target CU.

[0196] Step 503: The DU initiates an F1

[0215] Example 2:

[0216] like Image 6 As shown, it is a schematic flowchart of another complete method for switching DUs between CUs according to an embodiment of the present application.

[0217] Step 601: After the DU satisfies the handover trigger condition, it is determined that the source CU is handed over to the target CU.

[0218] The triggering condition of the handover can be any condition such as time-based, location-based, RRM measurement-based, or CU or DU load information.

[0219] In step 602, the DU obtains the information of the target CU based on pre-configuration and other means.

[0220] The information of the target CU may include some or all of the following: ID (gNB ID) of the target CU, name of the target CU, TNL address of the target CU, and OAM configuration information of the DU.

[0221] It should be noted that the OAM configuration information of the DU here may include configuration information such as the frequency, PCI, and CGI of the DU when
