Problems solved by technology

However, this method leads to another new problem at the same time: since the current cell broadcast information only informs the UE of the PLMN list supported by the cell and the cell Identity of the cell, when the PLMN ID in the Global eNB ID is related to the cell When the supported PLMN IDs are different, in the Automatic Neighbor Relation (ANR, Automatic Neighbor Relation) function, when the UE reports the ECGI of the unknown neighboring cell (the primary PLMN ID and cell Identity in the cell broadcast) to the network, the network will It is impossible to correctly identify which eNB the unknown neighboring cell belongs to, so that the correct specific information of the cell cannot be obtained, which will not only affect the integrity and correctness of the ANR function, but may also affect the handover performance

Embodiment 1

[0050] In non-network sharing, during the ANR process, the network side successfully identifies the unknown neighbor cell reported by the UE, and successfully adds the unknown neighbor cell. Figure 4 It is a flow chart of a method for cell identification in an embodiment of the present invention, such as Figure 4 As shown, the method for cell identification in this example specifically includes the following steps:

[0051] Step 401, after the eNB system control plane module is powered on, read the globally unique identifier of the eNB from the front-end database and save it; read the configuration of the cell under the eNB, including the layer 3 cell ID, the PLMN ID supported by the cell, and the cell wireless parameters, and save them; under non-network sharing, the cell supports only one PLMN ID, which is the same as the PLMN ID in the global unique identifier of the eNB.

[0052] Step 402, the eNB system control plane module establishes each cell according to the config...

Embodiment 2

[0062] Under network sharing, during the ANR process, the network side successfully identifies the unknown neighbor cell reported by the UE, and successfully adds the unknown neighbor cell. Figure 5 It is a flow chart of the method for cell identification in Embodiment 2 of the present invention, such as Figure 5 As shown, the method for cell identification in this example specifically includes the following steps:

[0063] Step 501, after the eNB system control plane module is powered on, read the global unique identifier of the eNB from the front-end database and save it; read the configuration of the cell under the eNB, including the layer 3 cell ID, the PLMN ID supported by the cell, and the cell wireless parameter, and save it; in this example, in the case of network sharing, there can be multiple PLMN IDs supported by the cell, which can be the same as or different from the PLMN ID in the global unique identifier of the eNB. Therefore, the identification of the base s...

Abstract

Disclosed in the present invention are a method, apparatus and an evolved Node B(eNB) for cell identification, wherein the method for cell identification comprises: when a global Public Land Mobile Network Identity(PLMN ID)is set up for cells in the same eNB, the global PLMN ID is made as the PLMN ID in the respective Evolved Cell Global Identifier(ECGI) by the said cells in the eNB and is broadcast. Using the technical scheme of the present invention, in the Automatic Neighbour Relation (ANR) function, the network side, according to the ECGI of an unknown neighbour cell reported by a User Equipment (UE), can accurately match the cells in the corresponding eNB, ensure the integrity and accuracy of the ANR function and no omissions of neighbour relations, and then ensure the success rate of UE handoff.

Description

technical field [0001] The present invention relates to a cell identification technology, in particular to a cell identification method, device and base station under the cell sharing situation. Background technique [0002] A Cell Global Identifier (CGI, Cell Global Identifier) ​​is an identifier that can uniquely identify a cell in the entire network. In a Long Term Evolution (LTE, Long Term Evolution) system, an Evolved Cell Global Identifier (ECGI, Evolved Cell Global Identifier) ​​is used to distinguish different cells. ECGI is composed of two parts: PLMN ID (Public Land Mobile Network Identity) and cell identity (cell Identity). The PLMN ID is used to distinguish different operator networks, and the PLMN IDs of different operator networks are different. The cell Identity is a 28-bit long bit stream consisting of two parts, the first 20 bits are eNB ID (EvolvedNode B Identity), and the last 8 bits are layer 3 cell ID. The eNB ID is unique under the same PLMN network, ...
