  • 3GPP 3rd Generation Partnership Project
  • the location information request initiated by the requester to the target UE is divided into two types: immediate location information request and delayed location information request.
  • Immediate location information request means that the LCS system immediately locates the target UE after receiving the location information request from the requesting end to the target UE, and then immediately sends the positioning result to the requesting end, that is, the LCS system receives the location information sent by the requesting end. After the request, the current location information of the target UE is provided to the requesting end immediately.
  • Delayed location information request refers to the requesting end requesting the LCS system to provide the location information of the target UE to it at a future point in time or when a certain event occurs. That is, after the LCS system receives the location information request from the requesting end to the target UE, it needs to go through A delay After the delay event is triggered, the requester is provided with the current location information of the target UE.
  • 3GPP allows the requester to request the LCS system to provide it with the location information of the target UE periodically, that is, the requester defines the start time point and the end time point and a certain periodic logic, and requires the LCS system to follow the periodic logic to the It provides location information of the target UE.

Since the location service belongs to a service subscribed by the target UE, at some times, it may be necessary to request the LCS system to close the location service to the requesting end for the purpose of protecting its private information, that is, to deactivate the location service; In addition, when the target UE roams out of the home service area, the positioning cost may increase due to roaming. Due to the consideration of charges, the target UE may also need to request the LCS system to close the location service to the requesting end.
