Mobile positioning services in existing mobile communication systems are mainly used for emergency rescue, such as emergency rescue and positioning of users in emergency call scenarios; location-based information services, such as vehicle GPS applications, yellow pages, traffic information, weather Information, navigation information and tour guide services, etc.; location-triggered services, such as location-based management information and billing, etc.; tracking and asset management services, such as vehicle dispatching/tracking/monitoring/anti-theft, material tracking, and elderly and child monitoring services, etc. .

In order to provide location services, the LTE system introduces positioning features. The main requirement for the positioning feature is to support both the control plane positioning process and the user plane positioning process. Positioning on the control plane mainly refers to the transmission of positioning-related information through control signaling; positioning on the user plane refers to support for the OMA SUPL (Open Mobile Alliance Secure User Plane Location) protocol, that is, positioning-related information can be transmitted through OMA SUPL The protocol is used for transmission. On the wireless interface, it is user data, not control signaling.

Positioning methods are divided into positioning methods that support network-based (Network-based, E-SMLC-based) and UE-based (UE-based) positioning methods. The network-based positioning method means that the UE's position calculation is performed in the E-SMLC; the UE-based positioning method means that the UE's position calculation is performed within the UE.
