Description

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for transmitting a positioning message.

Background

Small data transfer (Small Data Transmission, SDT) techniques can be used for small amounts of data/signaling transfer in the inactive state. When a terminal (also called User Equipment, UE) moves after entering an inactive state and reselects to a new base station, a serving base station when the terminal initiates small data transmission may be different from a base station releasing the terminal to enter the inactive state, and at this time, the context of the terminal remains in the original base station, which is called an anchor base station. If the base station from which the terminal initiates SDT transmission is different from the anchor base station, the SDT technology based on random access channel (Random Access Channel, RACH) is divided into an SDT for anchor migration and an SDT for no anchor migration according to migration of all or part of terminal context through the network interface.

The terminal location in the inactive state is based on SDT technology. When positioning request (Mobile Terminated Location Request, MT-LR) of a mobile terminal is terminated for non-active state delay of a terminal, a Service base station is different from an anchor base station, the anchor base station decides a scene of not performing anchor migration, and according to a procedure of not performing terminal context migration by SDT, a positioning Service (LCS) event report between the Service base station and a core network and subsequent uplink and downlink messages all need to be forwarded through Xn application protocol (Xn Application Protocol, xnAP) messages between the Service base station and the anchor base station, and then interaction is performed between the anchor base station and the core network, however, at present, the behaviors between the Service base station and the anchor base station in the scene are not clear, including processing of a new air interface positioning protocol a (New Radio positioning protocol A, NRPPa) message by the anchor base station, allocation of sounding reference signal (Sounding Reference Signal, SRS) resources, measurement activation process and the like, so that the non-active state terminal uplink positioning procedure under the scene cannot be completed.

All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In order to facilitate a clearer understanding of the technical solutions of the embodiments of the present application, some technical contents related to the embodiments of the present application will be first described.

(1) LCS positioning business process

Fig. 1 is a schematic diagram of LCS location service flow provided in the related art, as shown in fig. 1, and the flow relates to a terminal, an access network node (e.g. a base station), an access and mobility management function (Access and Mobility Management Function, AMF) and a location management function (Location Management Function, LMF) network element for any location service. After the LMF receives the location service request, if the terminal is in CM-IDLE state (connection management-IDLE state), the AMF performs a network triggered service request defined in 3GPP standard protocol TS 23.502 to establish a signaling connection with the terminal and allocates a serving base station (e.g., a gNB or ng-eNB) to the terminal, i.e., before the procedure shown in fig. 1, it is assumed that the terminal is in a connected state.

The positioning business process shown in fig. 1 includes:

1.5 LCS entity of GC (core network) or service AMF or terminal, sends location service request to service AMF, requesting location service.

The amf forwards the location service request to the LMF.

And 3, the LMF and the serving base station and the possible neighbor base stations start a positioning process, and additionally or alternatively, the LMF and the terminal start the positioning process.

The lmf provides a location services response to the AMF and contains all the required results.

The AMF replies a location services response according to step 1.

(2) SDT technology based on radio access technology (Radio Access Technology, RAT)

SDT technology can be used for small amounts of data or signaling transmissions in the inactive state.

When the terminal moves after entering the non-connection state and reselects to a new base station, a service base station when the terminal initiates small data transmission may be different from a base station releasing the terminal to enter the non-connection state, and at this time, the context of the terminal remains in the original base station, which is called an anchor base station. If the base station of the terminal initiating SDT transmission is different from the anchor base station, the SDT technology based on RACH is divided into the SDT of anchor migration and the SDT of non-anchor migration according to the context of all or part of the terminal migrated through the network interface.

Fig. 2 is a schematic diagram of SDT flow provided by the related art, in which the terminal context does not migrate to an anchor point, and as shown in fig. 2, the SDT flow mainly includes:

1. the terminal sends a radio resource control (Radio Resource Control, RRC) resume request to the serving base station while sending uplink SDT data and/or uplink SDT signaling.

2. The serving base station identifies the anchor base station via Inactive-Radio Network Temporary Identifier (I-RNTI) and retrieves the context of the terminal via XnAP, the serving base station instructs the terminal to request an SDT session and possibly provide SDT related assistance information.

3. The anchor base station decides not to transfer the entire terminal context.

4. The anchor base station transfers part of the terminal context, including the SDT related radio link control (Radio Link Control, RLC) context.

5. The serving base station acknowledges receipt of the partial terminal context and provides an associated downlink transport network layer (Transport Network Layer, TNL) address. The terminal context is stored in an anchor base station, which maintains a packet data convergence protocol (Packet Data Convergence Protocol, PDCP) entity, and the serving base station establishes an SDT-related RLC context. Uplink/downlink User plane general packet service (GTP-U) tunnels are established for data radio bearers (Data Radio Bearer, DRBs) allocated to SDTs, if any, and uplink SDT data and/or signaling is forwarded to the anchor base station and then to the core network, such as an AMF or User plane function (User Plane Function, UPF).

6. The serving base station detects the end of the SDT session and sends a search terminal context acknowledge message indicating whether this is a normal SDT transmission end or a radio link problem.

7. After receiving the search terminal context confirmation message and deciding to terminate the SDT, the anchor base station responds to the search terminal context failure message, including an encapsulated RRC release message, to the service base station, which releases the established partial terminal context.

8. The serving base station transmits an RRC release message to the terminal.

9. If the RRC release message contains the suspension configuration, the terminal is converted into an RRC inactive state, otherwise, the terminal enters an RRC idle state.

(3) Uplink positioning process of non-active terminal

The terminal location in the inactive state is based on SDT technology. Fig. 3 is a schematic diagram of an uplink positioning procedure of an inactive state terminal provided in the related art, as shown in fig. 3, which mainly includes:

1. steps 1-21 of the periodic or triggered delay 5GC-MT-LR procedure specified in section 3GPP standard protocol TS 23.273 6.3.1 are performed and the terminal enters the RRC inactive state.

2. The terminal monitors for triggers or periodic events.

3. When an event is monitored, the terminal sends an RRC recovery request with SDT, and simultaneously sends an RRC uplink information transmission (UL Information Transfer) message, wherein the uplink information transmission message comprises an uplink non-access stratum transmission (UL NAS Transport) message, and a load container of the uplink non-access stratum transmission message comprises an LCS event report; the serving base station of the terminal may be the same as or different from the base station releasing the terminal to the RRC inactive state at this time.

4. The service base station sends an event report to the LMF; if the anchor base station has not changed, the serving base station will forward the LCS event report to the anchor base station via an XnAP message. Subsequent downlink non-access stratum messages (e.g., LCS event report acknowledgements) are also forwarded by the anchor base station to the serving base station via XnAP messages.

And 5, the LMF sends an NRPPa positioning information request message to the service base station through the anchor base station to request uplink SRS resources.

6. The serving base station determines uplink SRS resources.

7. The serving base station provides uplink SRS resource allocation to the LMF through the anchor base station.

The lmf transmits the uplink SRS resource configuration to a group of base stations.

And 9, the LMF sends an LCS event report confirmation message to the service base station, and the service base station sends the LCS event report confirmation message to the terminal through the downlink SDT.

10. And the service base station sends an RRC release message to enable the terminal to be kept in an RRC inactive state and carry uplink SRS resource configuration.

11. And the terminal transmits an uplink SRS signal, and the related base station receives and measures the uplink SRS signal.

12. The base station provides the measurement results to the LMF.

13. Steps 28-31 of the periodic or triggered delay 5GC-MT-LR procedure specified in section 3GPP standard protocol TS 23.273 6.3.1 are performed.

Specifically, when MT-LR positioning with inactive state delay is performed on a terminal, a service network device (for example, a service base station) is different from an anchor network device (for example, an anchor base station), and the anchor network device decides not to perform a scene of anchor transfer.

Optionally, the identity information of the service network device may include one or more of an Identity (ID) of the service network device, a name of the service network device, and TNL address information of the service network device.

After the positioning management function network element receives the first positioning message, the positioning management function network element can directly transmit the positioning message with the service network device according to the identity information of the service network device, including directly sending the positioning message to the service network device or directly receiving the positioning message sent by the service network device, without forwarding through anchor network device. The location messages interacted between the serving network device and the location management function network element may be transmitted transparently through the AMF.

According to the positioning message transmission method, the identity information of the service network equipment is sent to the positioning management function network element through the anchor network equipment, so that the positioning management function network element can directly transmit the positioning message between the service network equipment without forwarding through the anchor network equipment, the problem that the uplink positioning flow of the non-active terminal cannot be completed because some behaviors of the anchor network equipment and the service network equipment in the positioning process are not clear is avoided, and the uplink positioning flow of the non-active terminal in a scene of not performing anchor transfer can be supported.

Optionally, sending the first positioning message to the positioning management function network element includes:

Specifically, the anchor network device sends a first positioning message to the positioning management function network element, which may be the first positioning message sent to the positioning management function network element according to the first interface message after receiving the first interface message sent by the service network device. The first interface message is sent to the anchor network device after the serving network device determines the SRS resource configuration information.

Alternatively, the first interface message may be any interface protocol message for communication between network devices, such as an Xn interface message (XnAP message).

After receiving the second positioning information request message, the serving network device may configure SRS resources according to the SRS feature information. The SRS resources configured by the serving network device may be the same as or different from the SRS resources indicated by the SRS feature information.

After the serving network device determines the SRS resource configuration information, the serving network device may send the SRS resource configuration information to the anchor network device through the second interface message, to instruct the serving network device to configure the SRS resource, so that the anchor network device may generate an RRC release message according to the SRS resource configuration information, and send the RRC release message to the serving network device through retrieving the terminal context failure message, and then send the RRC release message to the terminal through the serving network device, to instruct the terminal to enter an inactive state or an idle state.
