Description

Method and device for determining node identifier on network side, storage medium and electronic device

Technical field

The present disclosure relates to the field of communications, and in particular, to a method and device for determining a node identifier on a network side, a storage medium, and an electronic device.

Background technique

In order to distinguish the respective services of different operators, different operators are allowed to perform independent identification allocation on the same base station or cell. In 5G NR, for the same physical cell (Physical Cell Identifier, PCI), different operators can assign a new air interface global cell identity (NCGI) in a site managed by them. Therefore, there may be multiple NCGI identifications in the same cell. According to the definition of the cell identity, the NCGI is a combination of a public land mobile network identity (PLMN ID) and a cell identity (Cell ID). The base station identity (gNB ID, gNB ID) is included in the Cell ID. Specifically, the gNB ID is located in the high-order field of the Cell ID, so different gNB IDs will have different Cell IDs.

However, in the scenario where the operators share network resources, the operator core network often cannot identify the corresponding target cell information, and it is necessary to perform cross-core network switching between different operator core networks. Because the core networks of different operators are independent of each other, the above-mentioned cross-core network handover process is prone to interaction failures, which in turn leads to handover failure.

detailed description

Hereinafter, the present disclosure will be described in detail with reference to the drawings and embodiments.

It should be noted that the terms “first” and “second” in the description and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

In order to further explain the cross-core network handover method in the case where operators share network resources, the working mode of the cross-core network handover is explained below with reference to FIG. 1.

As shown in Figure 1, the two core network modules (shown as oval modules in Figure 1) respectively represent the core network AMF (Access and Management Function) module 1 and the core network AMF module 2, and the core network AMF Module 1 and core network AMF module 2 use different operators PLMN1 and PLMN2 respectively; the two base station modules (represented as rectangular modules in Figure 1) represent the 5G base stations gNB1 and gNB2 respectively, and the terminal module represents the terminal UE, which is ready to perform cross-core Network switching UE. The interface between the gNB and the core network AMF is an NG interface, and the interface between the gNBs is an Xn interface.

The above gNB1 and gNB2 can be shared by different operators, that is, PLMN1 and PLMN2. Assume that the primary operator of gNB1 (PLMN) is PLMN1, and the primary operator of gNB2 (PLMN) is PLMN2; compared with the community sharing, the core networks AMF1 and AMF2 of operators PLMN1 and PLMN2 will maintain relative independence.

When the Xn interface is currently established, gNBs will exchange information about their respective serving cells. The serving cell information is usually in the form of a PCI + NCGI + PLMN list. For the serving cell information provided by gNB2, gNB1 can only obtain the PCI of the serving cell in gNB2, the NCGI corresponding to PLMN2, and the broadcast PLMN list. In the cross-core network handover scenario, it is assumed that the target cell identifier carried when the UE reports the measurement result to gNB1 is the PCI in gNB2. After receiving the measurement result, gNB1 will initiate a handover request acquisition message to AMF1, and the target base station identifier carried in the message For gNB2.

Since the main operator of the NCGI2 corresponding to the handover target cell PCI is PLMN2, the above PLMN2 belongs to AMF2, so AMF1 may not recognize the type of PLMN2, so AMF1 needs to pass relevant information to AMF2 for processing. Because the core networks of different operators remain relatively independent, that is, the independence between AMF1 and AMF2 is maintained, therefore, AMF1 and AMF2 may fail to interact and cause handover failure.
