As new applications and scenes which are increasingly emerging put higher requirements on positioning delay, security and the like, the positioning process based on the current architecture has some problems in supporting low-delay positioning requirements and services with higher regional security:
the time delay problem, the time delay of positioning mainly includes the time measured and calculated by the terminal, the time calculated by the positioning server, each intermediate node (such as the processing time of the authentication management function AMF and the base station) and the time delay of transmission between nodes. In the related art, positioning auxiliary data or a positioning request sent by a positioning server to a terminal needs to be sent to a core network first, then the core network sends the positioning auxiliary data or the positioning request to a base station, and then the positioning auxiliary data or the positioning request is sent to the terminal, and conversely, data received by the base station needs to be sent to the core network first and then sent to the positioning server, so that additional transmission and processing time delay are brought to some local positioning services deployed near the base station.
Safety issues, an application scenario of a type of positioning service at present is an industrial application, such as a factory, and for safety, a client in the vertical industry does not want to transmit data for positioning a terminal to an area outside the factory, but according to the existing architecture and process, the positioned data needs to be sent to an AMF, and generally, the AMF of a core network is centrally deployed and is deployed at a higher position in the network. Thus, the current architecture cannot meet the security requirements of some industry vertical applications.
