Description

Technical Field

[0001] This application relates to the field of wireless technology, and in particular to a positioning method, device, terminal, base station and positioning server. Background Technology

[0002] Currently, all existing UE positioning is completed in connected mode, where the UE and the base station are in a synchronous connection state. Uplink positioning in connected mode requires multiple interactions with the core network. The positioning process typically involves: the core network recommending a Sounding Reference Signal (SRS) to the serving base station; the serving base station then configuring and activating the SRS for the terminal and instructing the UE to send the SRS; and the Location Management Function (LMF) server instructing neighboring base stations to receive the SRS. Only then can each base station receive and measure the SRS signal sent by the UE in connected mode, completing uplink positioning.

[0003] Current standards introduce inactive-state positioning. When a UE detects a positioning request that meets the conditions, it is expected to initiate the UE positioning process directly in the inactive or even idle state. However, how the UE can send uplink positioning signals in the inactive or idle state so that surrounding base stations can receive them correctly is a significant problem. This is because there may be uplink synchronization issues, questions about when the base station should initiate uplink measurement, and whether the base station can constantly monitor SRS signals. Therefore, simply using the SRS positioning signal configured by the serving base station used in connected-state positioning as the positioning signal for the inactive or idle state cannot meet the positioning requirements. It is necessary to find a suitable positioning signal and process for use in the inactive or idle state to minimize the coupling of resource allocation between the UE and the core network, to more efficiently support positioning in the inactive / idle state, and to further reduce terminal power consumption. Existing technologies cannot meet these requirements. Summary of the Invention

[0146] In this embodiment of the invention, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0147] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0148] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0149] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX), and 5G New Radio (NR). All of these systems include terminal equipment and network equipment. The systems may also include a core network component, such as Evolved Packet System (EPS) and 5G system (5GS).

[0150] To address the issue that existing technologies for uplink positioning in terminals are all implemented in the connected state and cannot be applied to the inactive or idle state, this application provides a positioning method in which the terminal, when in an inactive or idle state, initiates uplink positioning in the inactive or idle state by sending a positioning wake-up instruction, thereby obtaining uplink positioning resources.

[0151] One embodiment of this application provides a positioning method, executed by a terminal, such as... Figure 1 As shown, the method includes:

[0152] S110, when the terminal is in an inactive or idle state, it sends a location wake-up instruction to the base station.

[0153] Using the positioning method described in the embodiments of this application, the terminal can send a positioning wake-up instruction to the base station in the inactive or idle state, that is, indicate uplink positioning in the inactive or idle state through a signal, so as to notify the base station to start uplink positioning.

[0154] Optionally, in this embodiment of the application, step S110, sending a location wake-up indication to the base station, includes:

[0155] Send a location wake-up instruction to the base station through one of the following: preset configuration resources, random access procedure, and dedicated signaling;

[0156] The preset configuration resources are either dedicated resources configured by the base station for the terminal, or dedicated resources broadcast by the base station.

[0157] Optionally, when the terminal is still in the cell where the serving base station is located when it was released from the connected state, the serving base station allocates dedicated resources for location wake-up to the terminal, and the terminal sends a location wake-up instruction to the serving base station through these dedicated resources; or, the base station broadcasts the dedicated resources for location wake-up within its cell, and the terminal sends a location wake-up instruction to the base station.

[0158] In this implementation method, the terminal uses dedicated resources for location wake-up as a location wake-up indication to notify the base station to enable uplink location for the terminal.

[0159] Optionally, the preset configuration resource can be to send a preset preamble code at a preset time on the Physical Random Access Channel (PRACH).

[0160] Optionally, in this embodiment of the application, a location wake-up instruction is sent to the base station through preset configuration resources, including one of the following:

[0161] A location wake-up indication is sent to the base station by sending a preset preamble at a preset time on the Physical Random Access Channel (PRACH).

[0162] By sending a preset preamble at a preset time on the preset physical random access channel PRACH to send message 1 or message A of the random access procedure, a location wake-up indication is sent to the base station.

[0163] A location wake-up instruction is sent to the base station via dedicated signaling.

[0164] Optionally, sending a location wake-up indication to the base station via dedicated signaling includes, but is not limited to, sending a location wake-up indication via at least one of the following:

[0165] Terminal identifier, terminal location request type, and wake-up type.

[0166] Optionally, wake-up types include periodic wake-up and event-based wake-up.

[0167] Optionally, a location wake-up indication is sent to the base station by transmitting a preset preamble at a preset time on the Physical Random Access Channel (PRACH), including:

[0168] When a terminal is released from a connected state by the base station and enters an inactive or idle state, if the base station sends a connection release message to the terminal, the base station allocates a preset timing and a preset preamble for the terminal to send a location wake-up indication; or

[0169] The base station broadcasts dedicated resources within its cell for location wake-up. When a terminal needs to send an uplink location signal in an inactive or idle state, it first receives a system message to obtain the optional resources within the cell used to apply for location services, that is, to send a location wake-up instruction.

[0170] Optionally, when the base station is the base station that the terminal was connected to before entering the inactive or idle state, when the terminal is released from the connected state by the base station and enters the inactive or idle state, if the base station sends a connection release message to the terminal, the base station allocates a preset timing and a preset preamble for the physical random access channel (PRACH) for the terminal to send a location wake-up indication; optionally, the base station also allocates preset uplink positioning resources for the terminal to send an uplink positioning signal.

[0171] In this implementation, when the base station is the base station that the terminal was connected to before entering the inactive or idle state, the terminal sends a preset preamble to the base station at a preset time through the Physical Random Access Channel (PRACH) to send a location wake-up instruction.

[0172] Furthermore, by storing the preset timing and preset preamble of the Physical Random Access Channel (PRACH) allocated to the terminal, as well as the terminal information such as the terminal identifier, the base station determines that it has received the location wake-up instruction sent by the terminal after receiving the preset preamble sent by the terminal through the preset timing of the PRACH, based on the correlation between the stored terminal identifier and the corresponding preset timing and preset preamble of the PRACH.

[0173] Further, optionally, the base station sends to the positioning server a preset timing and preset preamble for the Physical Random Access Channel (PRACH) allocated to the terminal for sending a positioning wake-up indication, a preset uplink positioning resource for sending an uplink positioning signal, and a terminal identifier.

[0174] Furthermore, based on the received location wake-up instruction, the base station sends a location reporting message from the terminal to the location server. This location reporting message includes a terminal identifier, used for the terminal to request an uplink location signal. Based on the received terminal identifier, the location server determines the corresponding preset uplink location resources and sends these resources to at least one neighboring base station, notifying it to prepare to receive the uplink location signal from the terminal.

[0175] Based on this, the base station and its neighboring base stations begin preparing to receive uplink positioning signals sent by the terminal.

[0176] This implementation utilizes the preset configuration resources allocated by the serving base station for sending location wake-up instructions and the preset uplink positioning resources for sending uplink positioning signals. This ensures a one-to-one correspondence between the preset configuration resources, the preset uplink positioning resources, and the terminals in the cell where the base station is located. This bypasses the steps required in existing mechanisms, such as random access, establishing a connection between the terminal and the core network, and finally exchanging uplink positioning signals through the core network. Without moving the terminal from the source base station, it efficiently completes the transmission and reception of uplink positioning signals in inactive or idle states, improving the terminal's positioning efficiency in these states, significantly reducing power consumption, latency, and numerous signaling processes.

[0177] In another implementation, the base station broadcasts dedicated resources within itself for location-based wake-up, specifically:

[0178] Each cell of the base station is assigned a dedicated Physical Random Access Channel (PRACH) with a preset timing and a preset preamble, which is used by the terminal to request location services, i.e., to send a location wake-up instruction.

[0179] The base station broadcasts the preset timing and preset preamble of the location-specific Physical Random Access Channel (PRACH).

[0180] When a terminal needs to send an uplink positioning signal in an inactive or idle state, it first receives a system message to obtain the available resources within the cell for applying for positioning services, that is, for sending a positioning wake-up instruction.

[0181] In this implementation method, optionally, a location wake-up instruction is sent to the base station through preset configuration resources, including:

[0182] By sending a preset preamble at a preset time on the Physical Random Access Channel (PRACH), message 1 or message A of the random access procedure is sent to the base station, and a location wake-up indication is sent.

[0183] Specifically, when using the four-step random access method, the terminal uses the preset physical random access channel PRACH, which is dedicated to sending location wake-up indication, and the preset preamble transmission message 1 broadcast by the base station;

[0184] Based on the received message 1, the base station determines that the received message 1 is a location wake-up indication sent by one of the terminals through the preset physical random access channel PRACH and the preset preamble.

[0185] Furthermore, the base station can send message 2 to the terminal based on the received message 1. Optionally, message 2 includes an uplink positioning resource index pre-configured by the base station.

[0187] The base station sends message 4 to the terminal based on the received message 3. The message 4 includes the uplink positioning resources configured by the base station for the terminal based on the uplink positioning resources requested by the terminal.

[0188] When using the two-step random access method, the terminal uses the preset physical random access channel PRACH, which is dedicated to sending the location wake-up indication, and the preset preamble transmission message A, which is broadcast by the base station.

[0189] Based on the received message A, the base station determines that the received message A is a location wake-up indication sent by one of the terminals through the preset physical random access channel PRACH and the preset preamble.

[0190] According to message A, the base station sends message B to the terminal, which includes uplink positioning resources configured for the terminal.

[0200] In this implementation method, using a four-step random access process, the terminal sends a location wake-up instruction to the base station and receives uplink location resources allocated to the terminal by the base station.

[0216] Optionally, after sending a location wake-up instruction to the base station via message 3 of the random access procedure, the terminal receives uplink location resources allocated by the base station via message 4; after sending a location wake-up instruction to the base station via message A, the terminal receives uplink location resources allocated by the base station via message B.

[0217] The positioning method described in this application, after sending a positioning wake-up instruction to the base station and receiving uplink positioning resources configured by the base station for uplink positioning signal transmission to the terminal, further includes:

[0218] Using preset uplink positioning resources, an uplink positioning signal is sent to the base station;

[0219] Wherein, the preset uplink positioning resources are dedicated resources pre-configured by the base station for the terminal; or

[0220] The preset uplink positioning resources are the uplink positioning resources allocated to the terminal by the base station after the terminal sends a positioning wake-up instruction to the base station.

[0221] Optionally, in the positioning method, the uplink positioning signal includes a PRACH channel and / or an SRS signal.

[0222] In one embodiment, optionally, when the base station is the serving base station connected to before the terminal enters the inactive or idle state, the serving base station pre-allocates the preset uplink positioning resources to the terminal for the terminal to send the uplink positioning signal.

[0223] In another embodiment, optionally, when the base station is another base station that the terminal was connected to before entering the inactive or idle state, after receiving the location wake-up instruction sent by the terminal, the base station allocates the preset uplink positioning resources to the terminal for sending uplink positioning signals.

[0224] Optionally, in this embodiment of the application, after receiving the uplink positioning resources configured by the base station for uplink positioning signal transmission for the terminal, the method further includes:

[0225] Send an uplink positioning request to the base station;

[0226] The uplink positioning request is used to request the execution of uplink positioning service, and the uplink positioning request includes a Temporary Mobile Subscriber Identity (S-TMSI).

[0227] Optionally, the uplink positioning request is sent via an RRC request, including the S-TMSI and information requesting the execution of uplink positioning services, such as the reason for the request (continue uplink positioning service) and the corresponding Network Access Server (NAS) information, so that the base station can establish a connection between the terminal and the core network for the terminal's uplink positioning. In the positioning method described in this application embodiment, when the terminal starts sending uplink positioning signals, it uses a preset timing and a preset preamble of the Physical Random Access Channel (PRACH) allocated by the base station to send a positioning wake-up indication to the base station, notifying the base station that it is about to start sending uplink positioning signals.

[0228] Optionally, the transmitted uplink positioning signal includes an SRS signal and / or a PRACH channel.

[0229] Optionally, when the uplink positioning signal sent by the terminal is an SRS signal, the base station broadcasts candidate resources for sending SRS signals in the system message for inactive or idle states, and the base station pre-sends the SRS resources broadcast by the cell to the positioning server.

[0230] When the uplink positioning signal sent by the terminal is the PRACH channel, the base station pre-allocates the PRACH channel resources allocated in the cell for uplink positioning signals and sends them to the positioning server.

[0231] When a terminal is in an inactive or idle state and is preparing to send an uplink positioning signal, the terminal first sends a positioning wake-up indication, such as by sending a preset preamble at a preset time on the Physical Random Access Channel (PRACH). After receiving the positioning wake-up indication, the base station determines that the terminal is about to send an uplink positioning signal.

[0232] In this embodiment of the application, optionally, the terminal uses preset uplink positioning resources to send uplink positioning signals to the base station. The preset uplink positioning resources can be dedicated resources pre-configured by the base station for the terminal, or a resource pool pre-configured by the base station in a broadcast message. After the base station receives the positioning wake-up instruction sent by the terminal, it allocates uplink positioning resources to the terminal according to the broadcast resource pool.

[0233] In this embodiment of the application, optionally, the preset uplink positioning resources allocated by the base station to the terminal are sent to the core network through the New Radio Positioning Protocol A (NRPPa) container, such as to the positioning server. After receiving the preset uplink positioning resources configured for the terminal, the core network sends the preset uplink positioning resources to other base stations so that each base station can receive uplink positioning signals.

[0234] The positioning method described in this application embodiment may be, but is not limited to, the following premise for performing the positioning in the above implementation: the application layer location service (LCS) request has been sent to the positioning server, the terminal has established a connection with the positioning server, the terminal has been released into an inactive or idle state, but the LCS request has not been completed and responded to.

[0235] The following are examples illustrating specific embodiments of the positioning method described in this application.

[0236] Example 1

[0237] In this first embodiment, taking the example of a cell where the terminal is still in the cell where the serving base station is located after the terminal has been released from the connected state to the idle state or the inactive state, the application scenario that needs to determine the terminal location is under the delayed deferred location request (MT-LR) service or the mobile originated location request (MO-LR) service.

[0238] Specifically, in this embodiment, such as Figure 2 As shown, the specific implementation process of the terminal performing uplink positioning includes the following steps:

[0239] S210, when the terminal is released from the connected state by the base station and enters the inactive state or idle state, if the base station sends a connection release message to the terminal, the base station allocates a preset timing and a preset preamble for the physical random access channel (PRACH) to the terminal for the terminal to send a location wake-up indication; optionally, the base station also allocates preset uplink positioning resources to the terminal for the terminal to send an uplink positioning signal.

[0240] S220, The terminal saves the preset timing and preset preamble of the Physical Random Access Channel (PRACH) allocated to the terminal, as well as the terminal information, such as the terminal identifier.

[0241] S230, the base station sends to the positioning server the preset PRACH timing and preset preamble for the physical random access channel allocated to the terminal for sending the positioning wake-up indication, the preset uplink positioning resources for sending the uplink positioning signal, and the terminal information.

[0242] S240, when the terminal is preparing to send an uplink positioning signal to the serving base station, the terminal sends the preset timing and preset preamble of the Physical Random Access Channel (PRACH) configured for the terminal in step S210, that is, sends the PRACH to the base station, and notifies the base station that the terminal is preparing to send an uplink positioning signal through the positioning wake-up indication.

[0243] S250, the base station determines that it has received a location wake-up instruction sent by the terminal based on the association relationship between the stored terminal identifier and the preset PRACH timing and preset preamble of the corresponding physical random access channel; and sends the terminal information and the uplink location request information of the terminal corresponding to the terminal information to the location server.

[0244] S260, the positioning server determines the corresponding preset uplink positioning resources based on the received terminal identifier, sends the determined preset uplink positioning resources to at least one neighboring base station of the base station, notifies the at least one neighboring base station to prepare to receive the uplink positioning signal sent by the terminal, and enables the serving base station and the neighboring base stations of the serving base station to begin preparing to receive the uplink positioning signal sent by the terminal.

[0245] S270, The serving base station sends a signal activation instruction to the terminal to activate the uplink positioning resources configured for the terminal; wherein, this step is optional, and the serving base station sends the signal activation instruction to the terminal when the uplink positioning signal needs to be activated.

[0246] S280, the terminal uses the preset uplink positioning resources allocated to the terminal by the base station in step S210 to send an uplink positioning signal to the base station; optionally, the uplink positioning signal may include, but is not limited to, only include a PRACH signal and / or a dedicated SRS signal, and the PRACH signal may include a preset timing and a preset preamble of the PRACH.

[0247] This implementation utilizes the preset configuration resources allocated by the serving base station for sending location wake-up instructions and the preset uplink positioning resources for sending uplink positioning signals. This ensures a one-to-one correspondence between the preset configuration resources, the preset uplink positioning resources, and the terminals in the cell where the base station is located. This bypasses the steps required in existing mechanisms, such as random access, establishing a connection between the terminal and the core network, and finally exchanging uplink positioning signals through the core network. Without moving the terminal from the source base station, it efficiently completes the transmission and reception of uplink positioning signals in inactive or idle states, improving the terminal's positioning efficiency in these states, significantly reducing power consumption, latency, and numerous signaling processes.

[0248] The following embodiments illustrate the specific implementation method when a terminal leaves the cell of the serving base station connected in the connected state after entering the idle or inactive state from the connected state, in the deferred MT-LR scenario, and needs to send uplink positioning signals through other base stations besides the serving base station.

[0249] Example 2

[0250] In this embodiment, optionally, the base station determines and broadcasts candidate resources within the cell that are inactive or idle and can transmit uplink positioning signals. The specific process includes:

[0251] The base station first allocates candidate resources within its cell that can be used as uplink positioning signals for inactive or idle terminals. These candidate resources can be one or more combinations of the following resources:

[0252] Single or multiple SRS physical resource configurations and index identifiers.

[0253] PRACH channel resources may optionally include PRACH timing and a preset preamble.

[0254] Each base station sends the allocated candidate resources to the positioning server, informing it of the candidate uplink positioning resources for its cell.

[0255] The positioning server collects candidate uplink positioning resources sent by each base station and coordinates them to ensure that neighboring cells have staggered resource configurations. Optionally, if the positioning server detects conflicts in candidate uplink positioning resources between neighboring cells, it can send a configuration recommendation request to each base station.

[0256] Optionally, after receiving the configuration recommendation request from the positioning server, each base station updates its uplink positioning resource configuration and replies to the positioning server, informing it of the uplink positioning resources recommended by the positioning server.

[0257] Furthermore, the base station broadcasts the coordinated candidate uplink positioning resources in the system message;

[0258] When a terminal needs to send an uplink positioning signal in an inactive or idle state, it receives a system message and obtains the pre-configured candidate uplink positioning resources within the cell.

[0259] Example 3

[0260] In this embodiment, the base station broadcasts dedicated resources within its own memory used for location-based wake-up, specifically:

[0261] Each cell of the base station is assigned a dedicated Physical Random Access Channel (PRACH) with a preset timing and a preset preamble, which is used by the terminal to request location services, i.e., to send a location wake-up instruction.

[0262] The base station broadcasts the preset timing and preset preamble of the location-specific Physical Random Access Channel (PRACH).

[0263] When a terminal needs to send an uplink positioning signal in an inactive or idle state, it first receives a system message to obtain the available resources within the cell for applying for positioning services, that is, for sending a positioning wake-up instruction.

[0264] Example 4

[0265] In this embodiment, the terminal uses a four-step random access method to complete uplink positioning in the inactive or idle state, combined with Figure 3 As shown, the specific implementation process includes:

[0266] S310, the terminal sends message 1 according to the PRACH resources configured in the system message;

[0267] S320, after receiving message 1, the base station sends message 2 to the terminal; the sending of message 1 and message 2 is the same as the sending process of message 1 and message 2 in the existing four-step random access.

[0268] S330, the terminal sends message 3 to the base station, message 3 including at least one of the following:

[0269] Terminal information, such as terminal identity information ID and / or terminal identifier;

[0270] Location wake-up indication is used to request the allocation of uplink location resources, such as SRS resources or PRACH channel resources, from the terminal.

[0271] S340, the base station sends message 4 to the terminal based on the received message 3. The message 4 includes uplink positioning resources allocated by the base station to the terminal, such as SRS signal configuration and / or PRACH channel configuration.

[0272] Optionally, message 4 may also include at least one of the terminal contention resolution identifier and C-RNTI.

[0273] S350, the terminal sends an uplink positioning request, which may be an RRC request, including S-TMSI and information requesting the execution of uplink positioning services, such as the reason for the request (continue uplink positioning services) and the corresponding NAS information, so that the base station can establish a connection between the terminal and the core network for the terminal's uplink positioning.

[0274] S360: Based on the received uplink positioning request, the base station establishes a connection with the core network and sends the terminal information to the Access and Mobility Management function (AMF) unit of the core network.

[0275] S370, the base station sends the uplink positioning resources allocated to the terminal to the positioning server; specifically, the base station encapsulates the uplink positioning resources in a container and sends them to the positioning server via AMF;

[0276] S380, the positioning server sends the uplink positioning resources of the terminal to the neighboring base stations of the base station, notifying those neighboring base stations to prepare to receive the uplink positioning signal;

[0277] S390, after receiving message 4, the terminal sends an uplink positioning signal on the uplink positioning resources allocated to the terminal by the base station;

[0278] S391, the base station and its neighboring base stations receive uplink positioning signals, complete uplink positioning signal measurement, and report relevant measurement values ​​to the core network.

[0279] Example 5

[0280] In this embodiment, the terminal uses a four-step random access method to send a semi-persistent positioning signal in an inactive or idle state to complete the uplink positioning of the terminal.

[0281] Specifically, in this embodiment, steps S310 to S380 of embodiment four are included. Based on steps S310 to S380, when the uplink positioning signal is a semi-persistent signal requiring activation, the positioning server sends the terminal's uplink positioning resources to the neighboring base stations of the base station, notifying these neighboring base stations to prepare to receive the uplink positioning signal. Figure 3 As shown, it further includes the following steps:

[0282] S381, The positioning server sends activation information to the base station to activate the uplink positioning signal;

[0283] S382, the base station activates the uplink positioning signal at the expected time and sends an activation command to the terminal.

[0284] After receiving the activation command, the terminal sends an uplink positioning signal on the uplink positioning resources allocated to the terminal by the base station, which is to execute step S390.

[0285] In the above embodiments four and five, the terminal initiates random access based on the PRACH resources configured in the system message, and the location wake-up indication (used to request location signal configuration) is carried through message 3. This method can reduce the consumption of dedicated resources.

[0286] Example 6

[0287] In this embodiment, compared to embodiments four and five, a dedicated random access resource configuration is adopted to send a location wake-up instruction. This dedicated random access resource configuration is displayed to the terminal in the manner shown in embodiment three, which can reduce information interaction, improve positioning efficiency, reduce positioning latency and terminal power consumption.
