[0100] In some embodiments, the network device 102 may include at least one of an access network device and a core network device.

[0108] The following embodiments of the present disclosure may be applied to the information processing system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The information processing system may include all or a portion of the entities shown in FIG1 , or may include other entities outside of FIG1 .

Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0110] In some embodiments, the LMF and / or the UE may trigger the establishment of a user plane connection. The UE and / or the LMF may maintain an established user plane connection. The LMF may modify or terminate an established user plane connection between the UE and the LMF. Optionally, the user plane connection may be a connection between the UE and the LMF. Optionally, the UE may be a terminal.

[0111] In some embodiments, the LMF may send user plane information to the UE via a downlink non-access stratum (DL NAS) transmission message of the Access and Mobility Management Function (AMF); for example, the user plane information includes an Internet Protocol (IP) address and / or a fully qualified domain name (FQDN). If the LMF sends its FQDN to the UE, a Domain Name System (DNS) server or resolver is used to resolve the IP address of the LMF; for example, an Edge Application Server Discovery Function (EASDF) or a local DNS for local LMF address resolution. The UE uses a user equipment routing selection policy (URSP) including user plane positioning-related packet data unit (PDU) session parameters to establish a PDU session for user plane positioning; for example, the PDU session parameters include a dedicated data network name (DNN) and / or network slice selection assistance information (S-NSSAI). The Session Management Function (SMF) selects the PDU Session Anchor (PSA) User Plane Function (UPF) (located at the central site or local site) connected to the LMF for the PDU session based on S-NSSAI, DNN and / or UE location information.

[0112] In some embodiments, session interruption for local LMF services for user plane location can be supported by pre-configuring the SMF with the local LMF IP address and / or network prefix and its Data Network Access Identifier (DNAI) so as to locate a dedicated PDU session in a specific service area for local PSA and uplink classifier (UL CL) or branch point (BP) insertion.

[0113] In some embodiments, positioning signaling through the user plane has several benefits: it has a more efficient communication load of a direct connection from the LCS server to the UE; it may not require base station, AMF, LMF signaling processing for the Radio Resource Control (RRC), Next Generation Access Protocol (NG-AP) and Hypertext Transfer Protocol 2.0 (HTTP / 2) protocol stack; a single connection can handle multiple LCS sessions; depending on UE support, it can have multiple choices (for example, 3GPP LPP and OMA LPPe are both possible in the choice of positioning protocol).

[0114] In some embodiments, the Correlation ID and Routing ID are different terms for the same identifier. The term "Correlation ID" is used for the identifier in service operations between the AMF and LMF, while the term "Routing ID" is used for the identifier in NAS messages sent over the N1 reference point between the UE and AMF or between the PRU and AMF.

[0115] In some embodiments, the association ID may be assigned by the AMF or LMF.

[0116] In order to enable the AMF to distinguish between the Association IDs allocated by the LMF and the Association IDs allocated by the AMF, these two types of Association IDs may be selected from different ranges with or without a flag.

[0117] In some embodiments, the correlation ID is associated with an LCS session. If the same serving LMF has already allocated a delay routing ID, the delay routing ID can help the serving LMF identify the periodic or triggered positioning session, or can indicate to the LMF that it is acting as a default LMF.

[0118] In some embodiments, two possible ways of transmitting messages between the LMF and the UE may include transmission via the control plane or transmission via the control plane. Alternatively, the UE and the LMF may send messages via the control plane: UE-AMF-LMF. Alternatively, the UE and the LMF may send messages via the user plane: UE-LMF.

[0119] Optionally, the message may be transmitted via the user plane, including a location supplementary service message and / or an LPP message;

[0120] Optionally, the Routing ID is between the UE and the AMF, and the Correlation ID is between the AMF and the LMF. The Correlation IDs can be the same or different. The Correlation ID is associated with a specific LCS session. The Correlation ID or Routing ID can be used to identify the LMF and its LCS session.

[0121] In some embodiments, the user plane may support the Secure User Plane Location (SUPL) protocol and / or the Location Services User Plane Protocol (LCS-UPP); the LCS-UPP includes a UL LCS-UP transmission message and a DL LCS-UP transmission message.

[0122] Exemplarily, the content of the UL LCS-UP transmission message is shown in Table 1. The content of the UL LCS-UP transmission message may include Information Element Identity (IEI), Information Element (IE), Type / Reference (Type / Reference), Presence (Presence), Format (Format) and / or Length (Length); the length is the number of bytes; the payload can be a payload. The UL LCS-UP transmission message is sent by the UE to the LMF to transmit an LPP message or a location supplementary service message. Optionally, the location supplementary service message can be an LCS message. Here, the message type is UL LCS-UP transmission. The meaning is: dual meaning (i.e., related to initiating or terminating access and the network); the direction is: UE to network.

[0123] Table 1

[0124] Exemplarily, the content of the DL LCS-UP transmission message is shown in Table 1. The content of the DL LCS-UP transmission message may include information element identifier, information element (IE), type / reference (Type / Reference), presence (Presence), format (Format) and / or length (Length); the length is the number of bytes; the payload can be a payload. The DL LCS-UP transmission message is sent by the LMF to the UE to transmit an LPP message or a location supplementary service message. Optionally, the location supplementary service message can be an LCS message. Here, the message type is DL LCS-UP transmission. The meaning is: dual meaning (i.e., related to initiating or terminating access and the network); the direction is: network to UE.

[0125] Table 2

[0126] In some embodiments, the location supplementary service message and the LPP message may be transmitted via the user plane or the control plane.

[0127] In some embodiments, in the case of the control plane, location supplementary service messages and LPP messages are transmitted together with a routing ID (or correlation ID). The routing ID (or correlation ID) is associated not only with a specific LMF but also with a specific LCS session. For example, if a UE has multiple LCS sessions with the same LMF, the LMF can use different correlation IDs to distinguish between two LCS sessions of the same UE.

[0128] In some embodiments, in the case of user plane, if one user plane connection can be used for multiple LCS sessions, there is no parameter in the current UL or DL ​​LCS-UP transmission message that serves as a correlation ID (or routing ID) that can help the LMF identify the LCS session.
