Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0169] 5G New Radio (NR) introduces a variety of positioning technologies that enable terminal positioning. For uplink positioning and hybrid uplink and downlink positioning, the access network equipment must configure the terminal with an uplink positioning reference signal (PRS). The terminal then sends an uplink positioning reference signal (PRS) based on the PRS configuration.

[0170] In some embodiments, the access network device sends an RRC inactive uplink positioning reference signal configuration to the terminal through a radio resource control (RRC) connection release message. After the terminal performs cell reselection, the terminal releases the uplink positioning reference signal configuration configured by the access network device.

[0171] In some embodiments, the access network device configures the terminal with a sounding reference signal (SRS) configuration for positioning, including an SRS validity area. After the terminal reselects a cell, if the selected cell is still within the SRS validity area, the terminal can continue to transmit the SRS according to the original configuration.

[0172] In some embodiments, for the spatial relationship of SRS, used for positioning configuration in multiple cells of a terminal in an RRC inactive state, when suspending the transmission of SRS resources for positioning, the terminal should continue to monitor the spatial relationship of the configured reference signal (RS). If the terminal determines that it is accurately measuring, the terminal will resume SRS transmission.

[0173] That is, for an SRS configured with an SRS validity area, the terminal may decide to suspend SRS transmission or resume SRS transmission according to a spatial relation.

[0174] In some embodiments, there is no RRC connection between the terminal and the base station in the RRC_INACTIVE state. If the terminal moves to another cell or the tracking area (TA) timer expires in the RRC_INACTIVE state, it will stop sending SRS. At this time, the access network device that allocates SRS resources to the terminal is unaware of this and will continue to reserve SRS resources for the terminal. In addition, other cells participating in positioning measurements will also continue to measure the SRS signal, which will result in a waste of uplink resources and additional energy consumption of the access network device.

[0175] In some embodiments, the terminal instructs the access network device to suspend or resume SRS transmission through an RRC resume request, and carries a reason, or the terminal requests to update the spatial relationship of the SRS through an RRC resume request.

[0176] In the related art, when an access network device provides services to a terminal without the terminal's context information, if it receives transmission status information of an uplink signal sent by the terminal for positioning, the access network device does not know how to handle it because it does not have the terminal's context information. This is a problem that needs to be solved urgently.

[0177] Based on this, the embodiments of the present disclosure provide an information transmission method, an access network device, and a core network device. The method, which is performed by a first access network device, includes: receiving a first message sent by a terminal, wherein the first message includes transmission status information of an uplink signal used for positioning, and the first access network device does not have the context of the terminal; and sending the transmission status information to a core network device or a second access network device, wherein the second access network device has the context of the terminal. Thus, the first access network device can send the transmission status information of the uplink signal used for positioning to the second access network device or the core network device, so as to implement the scheduling of measurement resources for the uplink signal used for positioning, avoid resource waste, save energy consumption, and ensure the continuity of the positioning process.

[0518] In some embodiments, the access network device within the specific area includes at least one of a first access network device and a second access network device.

[0519] By implementing the embodiments of the present disclosure, the core network equipment can obtain the transmission status information of the uplink signal used for positioning, as well as the spatial relationship configuration information, to instruct the access network equipment in a specific area to perform corresponding resource reservation operations, thereby controlling the scheduling of measurement resources for the uplink signal used for positioning, avoiding resource waste and saving energy consumption, and ensuring the continuity of the positioning process.

[0520] In some embodiments, when a terminal in the RRC_INACTIVE state sends an RRC resume request to an access network device, if the access network device currently serving the terminal (serving gNB) is not the access network device that last served the terminal (Last Serving gNB), it can be understood that the access network device of the terminal's last connection has the terminal's context information, while the access network device currently serving the terminal does not have the terminal's context information.

[0521] In some embodiments, the process may be performed with reference to a small data transfer (SDT) process.

[0522] FIG6A is a flowchart of an SDT process with terminal context relocation.

[0523] FIG6B is a flowchart of an SDT process without terminal context relocation.

[0524] It should be noted that the relevant descriptions of FIG. 6A and FIG. 6B can be found in the descriptions in the related art and will not be repeated here.

[0525] It can be understood that the serving gNB currently serving the terminal (such as the first access network device in the above embodiment, the same below) is not the anchor gNB (or also called the last serving gNB) of the terminal (such as the second access network device in the above embodiment, the same below), and does not support how the serving gNB will handle the RRC resume request message including the transmission status information of the uplink signal used for positioning from the terminal.

[0526] 2. If the spatial relationship needs to be updated, in the separated architecture, updating the spatial relationship on the non-terminal anchor gNB is not supported.

[0527] Based on this, in order to facilitate understanding of the embodiments of the present disclosure, the following exemplary embodiments are provided.

[0528] In an exemplary embodiment, as shown in Figure 7A, the first access network device is a serving base station (gNB), the second access network device is an anchor base station (gNB), and the core network device is an LMF.

[0529] 101. The terminal sends an RRC resume request message to the serving gNB. Exemplarily, the RRC resume request message is the first message in the above embodiment.

[0530] 102. If the RRC resume request message includes SRS suspend or SRS resume information and information requesting an SRS configuration update, the serving gNB sends an XnAP retrieve UE context request message to the anchor gNB.

[0531] The message includes information related to the SRS transmission status, wherein the relevant information about the SRS transmission status includes at least one of the following information:

[0532] -SRS Suspend indication or SRS Resume indication;

[0533] - Reasons for suspending or resuming (e.g., spatial relationships);

[0534] -Updated spatial relations (generated by the serving gNB).

[0535] 103. The anchor gNB decides whether to perform context relocation based on the information received from 102. If it decides to perform without anchor relocation, the anchor gNB sends a terminal-related NRPPa message (e.g., a positioning information update message) to the LMF, where the NRPPa message includes the suspend indication / resume indication received from 102, the cause, and / or the updated spatial relationship, so that the LMF can perform further operations.

[0536] If the decision is to perform without anchor relocation, the anchor gNB sends a Retrieve UE context failure message to the serving gNB, including an RRC release message. The RRC release message includes the updated spatial relationship received in step 102, so that the receiving gNB can further send it to the UE (step 105) to perform further positioning operations.

[0537] In the disclosed embodiment, when the SRS transmission status changes, if the terminal returns to a new base station, context relocation is not required, and the SRS transmission status is indicated to the LMF so that the LMF can reasonably control the positioning resources, thereby improving the utilization of the positioning resources.

[0538] In another exemplary embodiment, as shown in Figure 7B, the first access network device is a serving gNB, the second access network device is an anchor gNB, and the core network device is an LMF.

[0539] 201 to 202 are consistent with 101 to 102 in FIG. 7A and are not described in detail here (the difference is that there may be no updated spatial relationship in 202).

[0540] 203. If the anchor gNB decides to perform anchor relocation, it sends a Retrieve UE context response message to the serving gNB.

[0541] 204. The serving gNB sends a terminal-related NRPPa message (e.g., a positioning information update message) to the LMF based on the positioning-related context information received from step 203, wherein the NRPPa message includes the updated spatial relationship so that the LMF can perform further positioning operations.

[0542] 205. The serving gNB sends an RRC release message to the UE, where the message includes the updated spatial relationship, so that the terminal can perform further positioning operations.

[0543] In the embodiment of the present disclosure, when the SRS transmission status changes, if the terminal returns to a new base station, it can obtain comprehensive positioning-related configuration information from the anchor base station and indicate the SRS transmission status to the LMF so that the LMF can reasonably control the positioning resources and improve the utilization of the positioning resources.

[0544] In another exemplary embodiment, as shown in Figure 7C, the first access network device (serving gNB) and / or the second access network device (last serving gNB) are base stations (gNB(s) in the area) in a specific area, and the core network device is LMF.

[0545] 301. The LMF determines an SRS transmission suspend indication or an SRS transmission resume indication. The LMF may determine the SRS transmission suspend indication or the SRS transmission resume indication in the following manner:

[0546] -LMF receives an SRS transmission suspend indication or an SRS transmission resume indication from the serving gNB;

[0547] -LMF receives an SRS transmission suspend indication or an SRS transmission resume indication from the last serving gNB;

[0548] -LMF receives an SRS transmission suspend indication or an SRS transmission resume indication from the terminal.

[0549] 302. The LMF sends a message (e.g., an SRS reservation request or other NRPPa message) indicating an SRS reservation to an access network device within a specific area, wherein the message indicating the SRS reservation includes at least one of the following information:

[0550] -Reserved SRS identification or configuration;

[0551] -SRS reservation suspend;

[0552] -SRS reservation resume;

[0553] The access network equipment in the specific area determines whether to continue to reserve or release the corresponding SRS resources based on the received information.

[0554] In the disclosed embodiment, access network devices in a specific area are aware of the transmission status of the SRS and decide whether to reserve or release corresponding positioning resources based on the status, thereby improving resource utilization.

[0555] In another exemplary embodiment, as shown in Figure 7D, the first access network device (serving gNB) or the second access network device (last serving gNB) is an example of a separated architecture including gNB-CU and gNB-DU, and the core network device is LMF.

[0556] 401. The gNB-CU receives an RRC resume request message from the terminal, which is consistent with 101 shown in Figure 7A and is not repeated here.

[0557] In step 402, the gNB-CU sends a first message to the gNB-DU based on the request in step 401 (e.g., requesting to update the spatial relationship). The first message may be an F1AP message. For example, the first message may be the second message or the fourth message in the above embodiment.

[0558] The first message includes configuration update request information, and the configuration update request information includes at least one of the following information:

[0559] -Spatial relationship update request information;

[0560] -Measurement results, such as measurement results for different beams.

[0561] The gNB-DU generates a new configuration based on the configuration update request information.

[0562] In some embodiments, the gNB-CU and gNB-DU have no UE context (i.e., the gNB-CU and gNB-DU are serving gNB-CU and serving gNB-DU), and the F1AP message is non-UE-associated signaling. For example, a new SRS configuration update request message is defined to request an SRS configuration update (e.g., requesting an update of a spatial relationship).

[0563] In some embodiments, the gNB-CU and gNB-DU have UE context (i.e., the gNB-CU and gNB-DU are the last serving gNB-CU and the last serving gNB-DU), and the F1AP message is UE-associated signaling, such as a positioning information request message.

[0564] In step 403, the gNB-DU sends a second message to the gNB-CU, where the second message may be an F1AP message. The second message includes configuration update information (e.g., updated spatial relationship).

[0565] After receiving the configuration update information, the gNB-CU sends the configuration update information to the terminal and / or LMF, corresponding to 404 and 405.

[0566] In some embodiments, the gNB-CU and gNB-DU have no UE context (i.e., the gNB-CU and gNB-DU are serving gNB-CU and serving gNB-DU), and the F1AP message is non-UE-associated signaling. For example, a new SRS configuration update feedback message is defined to feedback SRS configuration updates (e.g., feedback on updated spatial relationships).

[0567] In some embodiments, the gNB-CU and gNB-DU have UE context (i.e., the gNB-CU and gNB-DU are the last serving gNB-CU and the last serving gNB-DU), and the F1AP message is UE-associated signaling, such as a positioning information feedback message.

[0568] In the embodiment of the present disclosure, under a separated architecture, a UE in the RRC_INACTIVE state that is transmitting an SRS or a UE that wants to start positioning through pre-configured SRS information is supported to obtain a more accurate updated spatial relationship to ensure normal positioning.

[0569] The embodiments of the present disclosure further provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., a first access network device, a second access network device, a core network device, etc.) in any of the above methods.

[0570] It should be understood that the division of the various units or modules in the above device is merely a division of logical functions. In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

Taking a field programmable gate array (FPGA) as an example, it can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by configuring the configuration file, thereby realizing the functions of some or all of the above units or modules. All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.
