Abstract

The application discloses a positioning processing method and device and a storage medium, and comprises the following steps: an LMF receives a UE position request message sent by an AMF, wherein the UE position request message carries an identifier used to indicate that the LMF sends a UE position to an L-NEF; after the LMF performs UE position positioning, the LMF sends the UE position to the L-NEF. The L-NEF receives the UE position sent by the LMF; and the L-NEF sends the UE position to an AF, wherein the AF is an AF initiating the UE position request message.

Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a positioning processing method, device and storage medium. Background Technology

[0002] In current 5G networks, the process for an Application Function (AF) to request location information from a User Equipment (UE) is lengthy. The AF first sends an information disclosure request to the Network Exposure Function (NEF), which then forwards the request to the Gateway Mobile Location Centre (GMLC). The GMLC then sends a location report request to the Access and Mobility Management Function (AMF). After confirmation with the base station and the terminal, the AMF selects an appropriate Location Management Function (LMF). The LMF triggers interaction with the base station and performs UE location analysis using messages transmitted by the AMF, reporting the UE location results to the AMF. Upon receiving the results, the AMF reports them to the GMLC, which then informs the NEF. The NEF then notifies the AF of the UE's location information.

[0003] The shortcoming of the existing technology is that the AF's request for the UE's location has too long a delay, which cannot meet the needs of low-latency applications. Summary of the Invention

[0231] The inventor noticed the following during the invention process:

[0232] The UE location request process is lengthy and only involves the core AF requesting the UE's location. In edge computing scenarios, when the local AF wants to know the UE's real-time location, the entire process has a long latency, which cannot meet the needs of local applications.

[0233] Although L-NEF (Local NEF) was introduced in edge computing projects to ensure the availability of low-latency capabilities, the functionality and information provided by L-NEF are not fully defined.

[0234] Therefore, based on the existing process, this embodiment of the invention proposes a low-latency scheme for exposing UE location information to local applications. This scheme is based on the current process, while introducing L-NEF as a network function within the process, and adding related new interfaces and services. After the LMF calculates the UE location information, it directly notifies the L-NEF of the UE location information through direct interaction. This optimizes the previous process of UE location information feedback, instead of the LMF transmitting messages through AMF, GMLC, and core NEF before the core NEF notifies the L-NEF. This allows UE location information to be exposed to local applications in real time, effectively reducing the latency of the process for local applications to obtain the UE location.

[0235] However, it should also be considered that the existing positioning process is not static. It may not necessarily involve the LMF transmitting messages through the AMF, GMLC, and core NEF before the core NEF notifies the L-NEF. It may also involve other network functions or use other processes. Therefore, the following explanation mainly focuses on the first network function, the second network function, etc., among which:

[0236] The first network function can be AMF or local NEF;

[0237] The second network function can be a local NEF;

[0238] The third network function can be AF;

[0239] The fourth network function can be GMLC.

[0240] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0241] A positioning processing method, comprising:

[0242] LMF receives the first message sent by the first network function;

[0243] LMF sends a second message to the second network function.

[0244] In practice, the primary network function is either AMF or local NEF.

[0245] In practice, the first message is used to request UE location information, including first identification information and / or second identification information and / or third identification information.

[0246] During implementation, the first identification information indicates that the request must meet the low latency requirement.

[0247] In practice, the second identification information is the second network function identifier.

[0248] During implementation, the third identification information indicates that the second information will be sent to the second network function.

[0296] In practice, the identifier is sent by the L-NEF to the AMF via the GMLC after the L-NEF receives the UE location request message from the AF, and then sent to the LMF after the AMF determines the LMF.

[0297] The following examples will illustrate this.

[0298] Figure 6 The diagram illustrates a location processing flow for disclosing low-latency UE location information to local applications. The scheme for disclosing low-latency UE location information to local applications may include:

[0299] 1. In edge computing scenarios, the local application server's AF wants to know the UE's location information and sends an Nnef_EventExposure_Subscribe message to L-NEF.

[0301] 3. After receiving the message, GMLC retrieves the UE's identification information from UDM and sends a Namf_Location_ProvidePositioningInfo request message to AMF. The request includes the L-NEF's identifier and the identifier that the request needs to meet low latency requirements.

[0302] 4. After receiving the message, AMF initiates a network-triggered service request process. AMF initiates NAS LocationNotification (NAS: Non-Access-Stratum) and receives a reply.

[0303] 5. When selecting an AMF, the appropriate LMF can be chosen based on local configuration or through the NRF (Network Function Database).

[0304] 6. The AMF sends an Nlmf_Location_DetermineLocation request message to the LMF, which carries the identifier of the L-NEF and the identifier that the request needs to meet the low latency requirement.

[0305] 7. The LMF performs UE location positioning, which involves message passing by the AMF.

[0306] 8. When the LMF receives the identifier in the message sent by the AMF, it finds that the request has a low latency requirement and directly sends the obtained UE location information to the L-NEF.

[0307] 9. After receiving the UE location information reported by the LMF, L-NEF sends it to AF via the Nnef_EventExposure_Notify (Nnef-Capability Opening-Notification) message.

[0308] 10. The LMF sends an Nlmf_Location_DetermineLocation response message to the AMF to indicate that the UE location information has been sent to the L-NEF.

[0309] 11. The AMF sends a Namf_Location_ProvidePositioningInfo response message to the GMLC, indicating that the request has been successful.

[0310] 12. GMLC sends an Ngmlc_Location_ProvideLocation Response message to NEF to indicate that the request was successful and ends the process.
