Description
Technical Field
The invention relates to the technical field of wireless communication, and particularly provides a terminal identification method in a moving process.
Background
In order to ensure privacy of users and data security of terminals, in an LTE or NR system, when a terminal accesses a base station and moves between base stations, the base station cannot identify the terminal user, and only a core network can acquire the identity of the terminal according to NAS messages. Therefore, in some application scenarios that the unique identifier in the terminal moving process needs to be acquired, for example, a remote intelligent server is used for terminal data intelligent modeling, so that in a scenario that the wireless parameters of the terminal are optimized, the terminal identification can be completed only by intervention of a core network. This brings difficulties to some functions such as wireless mobility management optimization, service model modeling, parameter intelligent optimization, etc. for a specific terminal, if terminal identification needs to be performed without participation of a core network, NAS message parsing which is unreasonable and not beneficial to terminal information security needs to be performed. If the terminal identification of the core network participation is carried out, an S1 port/NG port message needs to be added, the cost of the core network is increased, and the user privacy and the data security are influenced.
In detail, when the same terminal is connected to the same base station, the terminal can be uniquely identified in the base station through CRNTI in the same cell, but after the inter-station handover occurs, effective terminal identification cannot be transmitted according to the existing standard interface, flow and implementation. For a cloud computing server which is connected with a plurality of base stations and uses terminal data for intelligent optimization, the wireless configuration parameter optimization can be better performed only by continuously tracking the terminal data.
When the terminal accesses a certain cell under a certain base station from the IDLE state, the cell allocates a unique identifier CRNTI under the cell to the terminal, and for the base station, the cell under the base station has a unique identifier. Each cell has a unique identity ecgi (lte) or NR-cgi (NR) for the same network.
According to the characteristics, when a specific terminal is accessed in a wireless network under the same network at the same time, the ECGI/NR-CGI + CRNTI can be used as the unique identifier of the terminal in the network. However, since CRNTIs in a cell are recycled, that is, after a terminal of a certain CRNTI leaves the cell, the cell may recycle the CRNTI to another terminal for use, which may cause confusion of terminal identification for an intelligent optimization cloud computing server connecting multiple base stations.
