Support of control plane positioning methods with a user plane location solution

A user equipment (UE) configured for supporting location services for the UE, the UE comprising:

• at least one wireless transceiver configured to wirelessly communicate with a wireless network;
• at least one memory;
• and
• at least one processor coupled to the at least one wireless transceiver and the at least one memory, the at least one processor configured to:
• transmit or receive one or more messages, via the at least one wireless transceiver, to initiate a Secure User Plane Location (SUPL) positioning session with a SUPL Location Platform (SLP), the SUPL positioning session using at least one uplink or uplink-downlink position method;
• transmit to the SLP, via the at least one wireless transceiver, an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• receive at least one message from a serving base station to configure and activate transmission of an uplink (UL) positioning reference signal (PRS) or a UL sounding reference signal (SRS);
• and
• perform the at least one uplink or uplink-downlink position method by transmitting the UL PRS or the UL SRS.

A user equipment (UE) configured for supporting location services for the UE, the UE comprising:

• means for transmitting or receiving one or messages to initiate a Secure User Plane Location (SUPL) positioning session with a SUPL Location Platform (SLP), the SUPL positioning session using at least one uplink or uplink-downlink position method;
• means for transmitting to the SLP an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• means for receiving at least one message from a serving base station to configure and activate transmission of an uplink (UL) positioning reference signal (PRS) or a UL sounding reference signal (SRS);
• and
• means for performing the at least one uplink or uplink-downlink position method by transmitting the UL PRS or the UL SRS.

A non-transitory storage medium including program code stored thereon, the program code is operable to configure at least one processor in a user equipment (UE) for supporting location services for the UE, the program code comprising instructions to:

• transmit or receive one or messages to initiate a Secure User Plane Location (SUPL) positioning session with a SUPL Location Platform (SLP), the SUPL positioning session using at least one uplink or uplink-downlink position method;
• transmit to the SLP an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• receive at least one message from a serving base station to configure and activate transmission of an uplink (UL) positioning reference signal (PRS) or a UL sounding reference signal (SRS);
• and
• perform the at least one uplink or uplink-downlink position method by transmitting the UL PRS or the UL SRS.

A method performed by a Secure User Plane Location (SUPL) Location Platform (SLP) for supporting location services for a user equipment (UE), the method comprising:

• transmitting or receiving one or more messages to initiate a SUPL positioning session with the UE, the SUPL positioning session using at least one uplink or uplink-downlink position method;
• receiving from the UE an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• and
• performing the at least one uplink or uplink-downlink position method by transmitting or receiving one or more positioning messages to or from a serving base station for the UE through the serving AMF using the identifier for the serving AMF and the identifier for the UE.

A Secure User Plane Location (SUPL) Location Platform (SLP) configured for supporting location services for a user equipment (UE), the SLP comprising:

• at least one external interface configured to communicate with entities in a wireless network;
• at least one memory;
• and
• at least one processor coupled to the at least one external interface and the at least one memory, the at least one processor configured to:
• transmit or receive, via the at least one external interface, one or more messages to initiate a SUPL positioning session with the UE, the SUPL positioning session using at least one uplink or uplink-downlink position method;
• receive, via the at least one external interface, from the UE an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• and
• perform, via the at least one external interface, the at least one uplink or uplink-downlink position method by transmitting or receiving one or more positioning messages to or from a serving base station for the UE through the serving AMF using the identifier for the serving AMF and the identifier for the UE.

A Secure User Plane Location (SUPL) Location Platform (SLP) configured for supporting location services for a user equipment (UE), the SLP comprising:

• means for transmitting or receiving one or more messages to initiate a SUPL positioning session with the UE, the SUPL positioning session using at least one uplink or uplink-downlink position method;
• means for receiving from the UE an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• and
• means for performing the at least one uplink or uplink-downlink position method by transmitting or receiving one or more positioning messages to or from a serving base station for the UE through the serving AMF using the identifier for the serving AMF and the identifier for the UE.

A non-transitory storage medium including program code stored thereon, the program code is operable to configure at least one processor in a Secure User Plane Location (SUPL) Location Platform (SLP) configured for supporting location services for a user equipment (UE), the program code comprising instructions to:

• transmit or receive one or more messages to initiate a SUPL positioning session with the UE, the SUPL positioning session using at least one uplink or uplink-downlink position method;
• receive from the UE an identifier for a serving Access and Mobility Management Function (AMF) for the UE and an identifier for the UE;
• and
• perform the at least one uplink or uplink-downlink position method by transmitting or receiving one or more positioning messages to or from a serving base station for the UE through the serving AMF using the identifier for the serving AMF and the identifier for the UE.
