- This design is mainly to facilitate the routing function: as long as a radio access network node knows the NCGI of a cell, it can gradually route to the gNB or en-gNB described in the cell according to its highest bits.
- the convenience of routing is crucial for many functions such as handover, air interface interference cancellation, and automatic neighbor relationship establishment.
- gNB-CU/DU separation technology In order to adapt to diverse deployment scenarios, the industry has proposed the gNB-CU/DU separation technology. This technique further subdivides a gNB or en-gNB into a CU and one or more DUs. The two are connected by F1 interface. According to the current technology, one DU can only be connected to one CU at the same time.

- the NCGI of the cell controlled by the gNB-DU is directly configured by the network administrator. Specifically, in the process of network deployment, before the gNB-DU is activated, the network manager will inform the gNB-DU which gNB-CU it should connect to, and the specific configuration of all the cells it controls, including the NCGI of these cells. specific value. After that, the gNB-DU will connect with the gNB-CU specified by the network management according to the configuration of the network management and establish an F1 interface, and then inform the gNB-CU of its own configuration information including the NCGI of the subordinate cell through the F1 interface. When the DU is fixed on the ground, the NCGI will generally remain unchanged thereafter.

- gNB-DUs are usually in motion, it is difficult to guarantee that a gNB-DU can always be connected to only one gNB-CU in practice. This also means that the gNB-DU needs to be migrated between different gNB-CUs, that is, disconnected from the old gNB-CU and connected to the new gNB-CU. Since the high-order bits of the CGI are strictly equal to the Global gNB ID or the Global en-gNB ID, the CGI also needs to be changed during the migration of the gNB-DU. If every gNB-DU migration requires network management to intervene, the signaling process will be very complicated and inefficient, and it will easily lead to errors.

- the DU Before the DU is migrated to the target CU, it is assumed that the DU is connected to the source CU (meaning that the channel of the transport layer and the protocol layer are connected), and the source CU decides to migrate the DU to the target CU at a certain moment, so the source CU sends a message to the target CU.
- Relocation request after receiving the relocation request sent by the source CU, the target CU decides to accept the relocation request, configures the first global identifier for the cell under the jurisdiction of the DU, and sends it to the DU, so that after the DU moves into the target CU, the cell under the jurisdiction of the DU can Use the first global ID.
