Description

Method, equipment and device for selecting positioning information
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method, a device, and an apparatus for selecting positioning information.
Background
In the following, a procedure of a mobile called Location request is described, fig. 1 is a schematic diagram of a process in which a network requests a UE (User Equipment) Location for an LCS (Location Services) client, and as shown in the figure, the following processes are mainly performed:
the description of the above figures is as follows:
step 101, the external Location service client sends a request to a GMLC (Gateway Mobile Location Center), where the request carries a target UE Identifier, which is usually a GPSI (general Public Subscription Identifier) or a SUPI (Subscription static Identifier).
Step 102, GMLC calls numjuecm _ Get (numjue connection Management _ Get) service operation to home UDM (Unified Data Management ) of target UE.
Step 103, the UDM returns the network address of the current serving AMF (Access and Mobility Management Function).
In step 104, the GMLC calls a Namf _ Location _ providedlocation service operation to the AMF to request the current Location of the UE.
Step 105, if the UE is in CM-IDLE (Connection Management-free; CM: connection Management) state, the AMF initiates a network-triggered service request process to establish signaling Connection with the UE.
Step 106, the AMF selects an LMF (Location Management Function) according to the NRF (Network storage Function) request or configuration information, and calls an Nlmf _ Location _ destination Location (Nlmf _ Location _ position) service operation to the LMF to request the current Location of the UE.
Step 107, the LMF performs a location procedure. Such as UE assisted positioning procedures, network assisted positioning procedures, etc. in the prior art. Since the application does not modify the specific positioning process, the details of the positioning process are not described here.
In step 108, the LMF returns Nlmf _ Location _ DetermineLocation Response (Nlmf _ Location _ decision Location return) to the AMF to return the current Location of the UE. The service operations include location estimation information, time, and accuracy.
Step 109, the AMF returns Namf _ Location _ Providelocation Response to the GMLC/LRF (Namf _ Location _ provide Location reply) to return the current Location of the UE.
Step 110, the GMLC returns a location service reply to the external location service client.
In the scheme of positioning access type selection, the following types are provided:
the AMF selects an access type: after receiving the Namf _ Location _ Providelocation service operation from the GMLC, the AMF decides which access type to use to transmit the Location information. For example, if the UE is in a CM-IDLE state in a 3GPP access and in a CM-CONNECTED (connection management-CONNECTED) state in a Non-3GPP access, the AMF chooses to send positioning signaling to the UE through an N3IWF (Non-3 GPP InterWorking Function, non-3GPP InterWorking Function network element) instead of paging the UE through the 3GPP access.
GMLC selects access type: when the GMLC receives a location request from an LCS client, the GMLC obtains information such as the access technology currently used by the UE, the state of the UE in different access networks, and the like from the UDM, and the GMLC determines which access technology to use according to the information.
The defects of the prior art are as follows:
on one hand, the UE may be connected to different PLMNs (Public Land Mobile networks) through different access networks, and different AMFs in the different PLMNs serve the UE, so that the AMFs only store contexts of a specific access Network and cannot select positioning information used in other access networks for the UE.
On the other hand, the GMLC can acquire information of different access networks to which the UE is connected from the UDM only when receiving a location request of the LCS client, and thus cannot negotiate location information with the UE before the location request arrives.

The GMLC obtains access network information of the UE and state information in different access networks from the UDM, and then the GMLC determines location information according to the information, user preferences, operator policy and application requirements. GMLC sends Location information related to MO-LR (Mobile Originated Location Request) to AMF, AMF forwards it to UE, GMLC sends Location information related to MT-LR (Mobile Terminated Location Request) to UDM.
Location information negotiation procedure initiated by NW (network):
the GMLC decides to update the location information, and the trigger condition of the decision may be that the operator policy is changed, the GMLC obtains the user preference from the UDM, and the GMLC updates the location information of the user.
