Description
Technical Field
The invention relates to the technical field of wireless communication, in particular to a terminal identification method in a mobile process.
Background
In order to ensure user privacy, terminal data security and other reasons, in an LTE or NR system, when a terminal is accessed to a base station and moves between the base stations, the base station cannot identify a terminal user, and only a core network can acquire the terminal identity according to NAS information. Therefore, in some application scenarios where a unique identifier in the terminal moving process needs to be acquired, for example, a remote intelligent server is used for intelligent modeling of terminal data, so that in a scenario where wireless parameters of the terminal are optimized, intervention of a core network is needed to complete terminal identification. The method brings difficulty to functions such as wireless mobility management optimization, service model modeling, parameter intelligent optimization and the like aiming at specific terminals, and if terminal identification is required under the condition that a core network does not participate, unreasonable NAS message analysis which is unfavorable for terminal information security is required. If the terminal identification participated in by the core network is carried out, the S1 port/NG port information needs to be newly added, the cost of the core network is increased, and the privacy and the data safety of the user are influenced.
In detail, for the same terminal, when the terminal is accessed under the same base station, the terminal can be uniquely identified by CRNTI under the same cell in the base station, however, after the inter-station handover occurs, the effective terminal identification cannot be transferred according to the existing standard interface, flow and implementation. For the cloud computing server which is connected with a plurality of base stations at the same time and uses the terminal data to perform intelligent optimization, the terminal data needs to be continuously tracked so as to perform wireless configuration parameter optimization better.
Since when a terminal accesses a certain cell under a certain base station from an IDLE state, the cell can allocate a unique identifier CRNTI under the cell for the terminal, and for the base station, the cells under the base station all have unique identifiers. Each cell has a unique identity ECGI (LTE) or NR-CGI (NR) for the same network.
According to this feature, when a specific terminal accesses in a wireless network at the same time and under the same network, the ECGI/NR-cgi+crnti can be used as a unique identifier of the terminal in the network. However, since the CRNTI in a cell is recycled, that is, after a terminal of a certain CRNTI leaves the cell, the cell can recycle the CRNTI to another terminal for use, which may cause confusion of terminal identities for an intelligent optimization cloud computing server connected to multiple base stations.
