Description

[0001] This application is a divisional application of the invention patent application filed on March 13, 2020, with application number 2020800005085 and title "Positioning Method and Apparatus, Communication Equipment and Storage Medium". Technical Field

[0002] This application relates to, but is not limited to, the field of wireless communication technology, and particularly to a positioning method and apparatus, communication equipment and storage medium. Background Technology

[0003] Fifth generation cellular mobile communication (5G) th Generation 5G Release 16 (R16) introduces various positioning technologies to locate User Equipment (UE) in Radio Resource Control (RRC) connected mode. For some of these positioning technologies, a Location Management Function (LMF) is required to provide positioning assistance information to the UE. Here, the LMF is a communication entity.

[0004] To conserve UE power and reduce positioning latency, 5G requires positioning of UEs in both RRC idle and RRC inactive states. For UEs in RRC connected state, since the LMF can determine the UE's serving cell, the LMF sends positioning assistance information to the UE via Long Term Evolution Position Protocol (LPP) messages. Specifically, the UE's serving base station sends the positioning assistance information to the UE via RRC messages in a transparent manner. Alternatively, the LMF can send the positioning assistance information to the base station via New Radio Positioning Protocol A (NRPPa) messages, and the base station then broadcasts it to the UE via system messages.

[0005] For UEs in RRC idle or RRC inactive states, the LMF cannot send location assistance information to the UE via LPP messages. UEs in RRC idle or RRC inactive states can obtain location assistance information by acquiring system messages or actively requesting location system messages. Therefore, sending location assistance information to UEs in RRC idle or RRC inactive states not only increases system overhead but also introduces location latency.

[0006] However, it is worth noting that obtaining location assistance information through system messages or by actively requesting location system messages results in high system overhead and long location latency for wireless systems. Summary of the Invention

[0007] This application provides a positioning method and apparatus, a communication device and a storage medium.

[0008] A first aspect of this application provides a downlink transmission method applied in a user equipment (UE), the method comprising:

[0009] The UE receives a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; the positioning assistance information is used by the UE to perform positioning measurements and obtain positioning results in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0010] A second aspect of this application provides a downlink transmission method, which is applied in a base station, the method comprising:

[0011] A Radio Resource Control (RRC) release message is issued, wherein the RRC release message carries positioning assistance information; wherein the positioning assistance information is used by the User Equipment (UE) to perform positioning measurements in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0012] A third aspect of this application provides a downlink transmission apparatus, which is applied in a user equipment (UE), the apparatus comprising:

[0013] The first receiving module is configured to receive a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; the positioning assistance information is used by the UE to perform positioning measurements and obtain positioning results in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0014] A fourth aspect of this application provides a downlink transmission apparatus, which is applied in a base station, and the apparatus includes:

[0015] The second sending module is configured to send a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; wherein the positioning assistance information is used by the User Equipment (UE) to perform positioning measurements in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0016] The fifth aspect of this application provides a communication device, including a processor, a transceiver, a memory, and an executable program stored in the memory and capable of being run by the processor, wherein when the processor runs the executable program, it executes a positioning method as provided by any of the technical solutions of the first or second aspect.

[0017] A sixth aspect of this application provides a computer-readable storage medium storing an executable program thereon, wherein the executable program, when executed by a processor, implements the positioning method provided by any of the technical solutions of the first or second aspect.

[0018] The technical solution provided in this application embodiment allows the UE to receive positioning assistance information from the RRC release message when entering an RRC idle state or an RRC inactive state (or other RRC disconnected state). Therefore, the UE does not need to specifically receive the positioning assistance information from system messages or request-based system messages, thus reducing signaling overhead. Simultaneously, when the UE is in the RRC disconnected state, once a positioning request is received, it can directly perform positioning measurements based on the positioning assistance information received in the RRC release message upon entering the RRC disconnected state, thereby obtaining positioning results. In the RRC disconnected state, the positioning results are reported to the base station. Thus, the UE does not need to switch to the RRC connected state and then obtain the positioning assistance information required for positioning measurements by receiving system messages or request-based system messages from the base station, thereby reducing positioning latency and improving positioning speed. Furthermore, the UE does not need to exit the RRC disconnected state and enter the high-energy-consuming RRC connected state simply for positioning measurements, thereby reducing the time the UE spends in the unnecessary RRC connected state, saving UE power consumption, and also reducing the power consumption caused by frequent switching between the RRC disconnected and RRC connected states.

[0035] Please refer to Figure 1 This illustration shows a schematic diagram of the structure of a wireless communication system provided in an embodiment of this disclosure. Figure 1 As shown, the wireless communication system is a communication system based on cellular mobile communication technology. The wireless communication system may include: a number of terminals 11 and a number of base stations 12.

[0036] Terminal 11 can be a device that provides voice and / or data connectivity to a user. Terminal 11 can communicate with one or more core networks via a Radio Access Network (RAN). Terminal 11 can be an Internet of Things (IoT) terminal, such as a sensor device, a mobile phone (or "cellular" phone), and a computer with an IoT terminal. For example, it can be a fixed, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted device. Examples include a station (STA), subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, terminal 11 can also be a device on an unmanned aerial vehicle (UAV). Alternatively, terminal 11 can also be a vehicle-mounted device, such as a vehicle computer with wireless communication capabilities, or a wireless communication device connected to an external vehicle computer. Alternatively, terminal 11 can also be a roadside device, such as a street light, traffic light, or other roadside device with wireless communication capabilities.

[0037] Base station 12 can be a network-side device in a wireless communication system. This wireless communication system can be a 4G system (also known as Long Term Evolution, LTE); or it can be a 5G system (also known as a New Radio, NR, or 5G NR system). Alternatively, it can be a next-generation system after 5G. In this case, the access network in the 5G system can be called NG-RAN (New Generation-Radio Access Network). Alternatively, it can be an MTC system.

[0038] In this embodiment, base station 12 can be an evolved NB (eNB) used in a 4G system. Alternatively, base station 12 can also be a gNB (gNB) using a centralized-distributed architecture in a 5G system. When base station 12 adopts a centralized-distributed architecture, it typically includes a central unit (CU) and at least two distributed units (DU). The central unit is equipped with a protocol stack of Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), and Media Access Control (MAC) layers; the distributed units are equipped with a physical (PHY) layer protocol stack. This disclosure does not limit the specific implementation of base station 12.

[0039] Base station 12 and terminal 11 can establish a wireless connection via a wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth-generation mobile communication network technology (4G) standard; or, the wireless air interface is a wireless air interface based on the fifth-generation mobile communication network technology (5G) standard, such as a new air interface; or, the wireless air interface can also be a wireless air interface based on a next-generation mobile communication network technology standard based on 5G.

[0040] In some embodiments, terminals 11 can also establish E2E (End to End) connections. Examples include V2V (vehicle to vehicle), V2I (vehicle to Infrastructure), and V2P (vehicle to pedestrian) communication scenarios in vehicle-to-everything (V2X) communication.

[0041] In some embodiments, the wireless communication system described above may further include a network management device 13.

[0042] Several base stations 12 are connected to network management device 13. Network management device 13 can be a core network device in a wireless communication system, such as a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, it can be other core network devices, such as a Serving Gateway (SGW), a Public Data Network Gateway (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS). The implementation of network management device 13 is not limited in this embodiment.

[0043] Figure 2 The diagram illustrates how the LMF (Location Assistance Message) sends location assistance information to the terminal based on the LPP (Location Assistance Message). For example, the LMF can transmit this information to the UE (User Equipment) through the base station.

[0044] like Figure 3A As shown, this embodiment provides a positioning method, which is applied in a user equipment (UE). The method includes:

[0045] S110: Receive a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; the positioning assistance information is used by the UE to perform positioning measurements and obtain positioning results in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0046] When the UE is in RRC disconnected state, the UE may receive a location request or may not receive a location request. However, if the UE receives the location request while in RRC disconnected state, it can obtain a location result based on the location assistance information.

[0047] Therefore, as Figure 3B As shown, in some embodiments, the method further includes:

[0048] S120: In response to the UE receiving a positioning request in the RRC disconnected state, positioning measurement is performed according to the positioning assistance information in the RRC disconnected state, wherein the RRC disconnected state includes: RRC idle state and RRC inactive state;

[0049] S130: Report the positioning results of the positioning measurement.

[0050] In the embodiments of this application, the UE device can be a variety of terminals that can connect to the base station, including but not limited to: mobile phones, tablets, vehicle-mounted devices, industrial equipment, wearable devices and medical devices.

[0051] In this embodiment of the application, before the UE switches from the RRC connected state to the RRC idle state or the RRC inactive state, or other RRC disconnected states, it will receive an RRC release message from the base station.

[0052] In this embodiment of the application, the RRC release message carries location assistance information.

[0053] The positioning assistance information may include information sent by the LMF to the base station based on the NRPPa protocol, which the base station temporarily stores and includes in the RRC release message before detecting the UE's switch from RRC connected state to RRC disconnected state. When the UE enters an RRC idle state or RRC inactive state (or other RRC disconnected state), it receives the positioning assistance information from the RRC release message. Therefore, the UE does not need to separately receive the positioning assistance information from system messages or request-based system messages, thus reducing signaling overhead. Simultaneously, when the UE is in RRC disconnected state, once a positioning request is received, it can directly perform positioning measurements based on the positioning assistance information received in the RRC release message upon entering the RRC disconnected state, thereby obtaining the positioning result. In the RRC disconnected state, the positioning result is reported to the base station. Thus, the UE does not need to switch to RRC connected state and then obtain the positioning assistance information required for positioning measurements by receiving system messages or request-based system messages from the base station, thereby reducing positioning latency and improving positioning speed. Furthermore, the UE does not need to exit the RRC disconnected state and enter the high-energy-consuming RRC connected state just because of positioning measurement. This reduces the time the UE spends in the unnecessary RRC connected state, thereby saving UE power consumption and reducing the power consumption caused by the UE frequently switching between the RRC disconnected and RRC connected states.

[0054] The positioning assistance information includes:

[0055] The positioning assistance information package includes the cell identifier and / or base station identifier of the positioning measurement; and the resource location information of the positioning reference signal of the positioning measurement.

[0056] In some embodiments, the cell identifier may be: the identifier of the last serving cell or the identifier of a neighboring cell of the last serving cell.

[0057] In other embodiments, the base station identifier may be: the identifier of the base station of the serving cell where the UE last stayed, or the identifier of the base station of the neighboring cell of the serving cell where the UE last stayed.

[0058] The terminal can identify the measurement object using the cell identifier and / or the base station identifier. During positioning measurements, the Position Reference Signals (PRS) transmitted by the cell or base station are measured. Therefore, the terminal needs to understand the resource location information of the PRS when performing positioning measurements. This resource location information indicates the time-frequency resources transmitted by the PRS.

[0059] In some embodiments, when the UE is in the RRC disconnected state, the UE will listen to the paging message when paging occurs, and the location request can be carried in the paging message.

[0060] In some embodiments, after receiving a paging message carrying a location request, the UE does not directly return a paging response. Instead, it performs location measurements based on the location request, obtains the location result, and then reports the location request to the base station in the paging response. At this time, the base station can either pass the received paging response through to the LMF (Local Management Function), or it can extract the location result from the paging response and forward it to the LMF.

[0061] In other embodiments, after receiving a paging message carrying a location request, the UE initiates random access and reports the location result during the random access process. Once the location result reporting is complete, the random access is terminated to maintain the UE in an RRC disconnected state. For example, the location result is reported in the random access request. When the base station receives a random access request carrying the location result, it can assume that the main purpose of the current random access request is to report the location result, and thus terminate the subsequent random access process. Alternatively, after receiving a random access request containing the location result, the base station can send an acknowledgment notification to the UE through a random access response. After receiving the acknowledgment notification, the UE terminates the random access process, thus maintaining the UE in an RRC disconnected state.

[0062] The positioning result includes: the UE's measurement value of the positioning reference signal; and / or, the UE's location information determined by the UE based on the measurement value of the positioning reference signal.

[0063] The measured values ​​of the positioning signal include, but are not limited to: the received power of the positioning reference signal and / or the time difference of the reference signal.

[0064] In some embodiments, S120 may include: in response to the UE receiving a valid location request in the RRC disconnected state, performing location measurement in the RRC disconnected state.

[0065] For example, such as Figure 4 As shown, S120 may include:

[0066] S121: In response to the UE receiving a positioning request in the RRC disconnected state, determine whether the positioning assistance information is valid;

[0067] S122: In response to the validity of the positioning assistance information, perform positioning measurement in the RRC disconnected state.

[0068] In this embodiment, it will be further determined whether the location assistance information is still valid when the UE receives a location request in the RRC disconnected state. If the location assistance information is still valid, it means that performing location measurement according to the location assistance information (e.g., one or more of the location configurations such as the location measurement method, the location measurement parameters, and the quality of service) can provide the location measurement required by the LMF and obtain the location result that meets the LMF requirements.

[0069] Therefore, in this embodiment, after receiving a location request, the UE does not immediately perform location measurement, but first determines whether the location assistance information is valid. If the location assistance information received by the UE from the RRC release message is still valid, it will perform location measurement in the RRC disconnected state based on the location assistance information currently stored in the UE.

[0070] In some embodiments, determining the effective time range of the positioning assistance information includes:

[0071] In response to the UE receiving the positioning request in the RRC disconnected state, if the timer for timing the effective time range has not expired, the positioning assistance information is determined to be valid; or, if the locator times out, the positioning assistance information is determined to be invalid.

[0072] For example, S122 may include:

[0073] In response to the UE receiving the positioning request in the RRC disconnected state, it is determined whether the current time is within the valid time range of the positioning assistance information;

[0074] and / or

[0075] In response to the UE receiving the positioning request in the RRC disconnected state, it is determined whether the UE is within the effective spatial range of the positioning assistance information.

[0076] Determining whether the positioning assistance information is valid can be done from multiple perspectives. The above provides time-based and space-based methods for determining validity.

[0077] In one embodiment, if the current time of receiving the location request is within the valid time range of the timing assistance information, then the location assistance information is valid; otherwise, the location assistance information is invalid.

[0078] In one embodiment, upon receiving a location request, it is determined whether the UE is currently within the effective control range of the location assistance information. For example, whether the cell the UE is currently camped on is one or more cells covered by the location assistance information. Another example is whether the latitude and longitude information of the UE's current spatial location is included within the effective spatial range of the location assistance information.

[0079] In some embodiments, determining whether the current time is within the valid time range of the positioning assistance information in response to the UE receiving the positioning request in the RRC disconnected state includes:

[0080] In response to the UE receiving the positioning request in the RRC disconnected state, it is determined whether the timer used to count the effective time range at the current time has timed out;

[0081] If the timer does not time out, the positioning assistance information is determined to be valid.

[0082] In other embodiments, the step of determining whether the location assistance information is within the valid time range of the location assistance information in response to the UE receiving the location request in the RRC disconnected state includes: if the locator times out, determining that the location assistance information is invalid.

[0083] After receiving the RRC release message, the UE can configure a timer, which starts counting down for a duration corresponding to the valid time range. Thus, upon receiving a location request, the UE can determine whether the timer has expired at the moment the request is received. If the timer has expired, it indicates that the current time is outside the valid time range of the location assistance information, meaning the location assistance information is invalid. If the timer has not expired, it indicates that the current time is within the valid time range of the assistance information, meaning the location assistance information is valid.

[0084] This is an executable method that uses a timer to distinguish between valid and invalid times within a valid time range.

[0085] In other embodiments, the effective time range can be calibrated by using world time; thus, at the current moment when a location request is received, the terminal will determine whether the current moment is within the effective time range based on the world time recorded by the terminal, and the terminal will not need to set an additional timer.

[0086] In summary, there are many ways to determine whether the current moment is within the valid time range, and the specific implementation is not limited to any of the above methods.

[0087] In some embodiments, determining the effective spatial range of the positioning assistance information includes:

[0088] In response to the UE receiving the positioning request in the RRC disconnected state, if the UE's camped cell is a cell included in the effective spatial range, the positioning assistance information is determined to be valid; or, if the UE's camped cell is not a cell included in the effective spatial range, the positioning assistance information is determined to be invalid.

[0089] For example, the step of determining whether the UE is within the effective spatial range of the positioning assistance information in response to the UE receiving the positioning request in the RRC disconnected state includes:

[0090] In response to the UE receiving the location request in the RRC disconnected state, it is determined whether the UE's camp cell is located within the cells included in the effective spatial range;

[0091] If the UE's camped cell is a cell included in the effective spatial range, the positioning assistance information is determined to be valid.

[0092] In another embodiment, the step of determining whether the UE is within the effective spatial range of the positioning assistance information in response to the UE receiving the positioning request in the RRC disconnected state includes:

[0093] If the UE's camp cell is not a cell included in the effective spatial range, the positioning assistance information is determined to be invalid.

[0094] The effective spatial range can be a geographical area defined by geographic landmarks such as latitude and longitude, or a network area defined by a cell in a wireless network. For example, an effective cell or a set of effective cells is set for the positioning assistance information. The network area corresponding to the cells within this effective cell or set of effective cells constitutes the effective spatial range. Specifically, the effective spatial range can be indicated by cell IDs in a cell identity (ID) list.

[0095] If the cell where the UE is currently camped is a cell in which the location assistance information is effective or a cell in the set of effective cells, then the location assistance information can be considered to be effective at least in the spatial dimension.

[0096] For example, when determining whether a location is valid, a UE can determine whether its current location is within the valid spatial range of the positioning assistance information based on the cell it is camped on, or by using latitude and longitude information obtained through Global Positioning System (GPS) or BeiDou satellite positioning.

[0097] By setting the effective time range and / or effective spatial range of the positioning assistance information, positioning measurements adapted to the corresponding time and / or space range can be achieved.

[0098] In some embodiments, the positioning assistance information includes at least one of the following:

[0099] The measurement configuration of the positioning reference signal is at least used to indicate the resource location of the positioning reference signal;

[0100] The cell public parameter configuration is used to configure the public channel for locating and measuring the cell to be measured;

[0101] Valid time range indication information is used to indicate the valid time range of the positioning assistance information;

[0102] Effective spatial range indication information is used to indicate the effective spatial range of the positioning assistance information.

[0103] The location of the positioning reference signal is added to the positioning assistance information. In this way, the UE can measure the positioning reference signal at the corresponding time domain resources and / or resource locations to achieve positioning measurement.

[0104] The common channels of the cell include, but are not limited to: the cell's broadcast channel, the common physical downlink control channel, etc. The cell to be measured for positioning measurement can be the cell where the UE is currently camped, or a neighboring cell of the currently camped cell.

[0105] The common channel configuration at least indicates the resource location of the common channel, so that the UE can receive the configuration for performing positioning measurements at the corresponding resource location, such as the aforementioned positioning parameter signal measurement configuration and / or positioning measurement configuration.

[0106] The positioning measurement configuration includes, but is not limited to, at least one of the following:

[0107] The positioning method includes, but is not limited to, at least one of the following: Downlink-Time Difference of Arrival (DL-TDOA), Uplink-Time Difference of Arrival (UL-TDOA), Downlink-Arrival of Angle (DL-AOA), and Enhanced Cell-IDentifity positioning method (E-CID);

[0108] The measurement parameters for positioning measurements include, but are not limited to: Position Reference Signals-Reference Signal Receiving Power (PRS-RSRP) and Position Reference Signals-Reference Signal Time Difference (PRS-RSTD).

[0109] Location service quality (QoS) requirements, which include: location accuracy and / or location latency.

[0110] The UE identifier used for location measurement, such as the UE's International Mobile Subscriber Identification Number (IMSI) or Temporary Mobile Subscriber Identification Number (TMSI), can inform the base station which UE to forward the location request to, or whether the location request needs to be sent via a paging message.

[0111] Based on the above-mentioned positioning assistance information, positioning measurements can ensure that the UE performs positioning measurements in accordance with the positioning method, positioning accuracy and / or positioning service quality required by the LMF, and reports the positioning results expected by the LMF.

[0112] Of course, the above are just examples, and the specific implementation is not limited to any of the above.

[0113] The effective time range indication information indicates the effective time range of the corresponding positioning assistance information, for example, indicating the timer's scheduled collection.

[0114] The effective spatial range indication information indicates the effective space of the positioning assistance information. For example, the effective spatial range indication information includes: a cell list; the cell range indicated by the cell identifiers in the cell list is the effective spatial range.

[0115] In some embodiments, the connection release message includes:

[0116] The first information unit (IE) carries indication information that instructs the UE to switch from RRC connected state to RRC disconnected state;

[0117] and / or

[0118] The second IE carries the aforementioned positioning assistance information.

[0119] The RRC connection release information was originally intended to instruct the UE to release the connection with the base station in order to switch from the RRC connected state to the RRC idle state or the RRC inactive state.

[0120] In this embodiment of the application, the RRC connection release information also carries the positioning assistance information.

[0121] When the RRC connection release information carries the location assistance information, the indication information and location assistance information that instruct the UE to switch from RRC connected state to RRC disconnected state can be indicated separately using different parts of the same IE, or different IEs can be used to indicate separately.

[0122] In this embodiment of the application, the indication information and the location assistance information in the RRC connection release message use different IEs. Thus, the RRC connection release message includes at least two IEs, namely the first IE and the second IE. Using independent IEs for indication facilitates encoding and decoding by both the sender and receiver.

[0123] In some embodiments, the RRC connection release information may use a pre-defined reserved sequence to indicate the positioning assistance information.

[0124] In some embodiments, the method further includes:

[0125] In response to the failure of the positioning assistance information, positioning measurement is performed in the RRC connected state.

[0126] For example, the step of performing positioning measurement in the RRC connected state in response to the failure of the positioning assistance information may include: switching from the RRC disconnected state to the RRC connected state; and performing positioning measurement in the RRC connected state after switching to the RRC connected state.

[0127] In one embodiment, performing positioning measurements after switching to RRC connected state may include performing positioning measurements based on positioning assistance information under RRC connected state.

[0128] In another embodiment, performing positioning measurements in the RRC connected state includes:

[0129] After switching to RRC connection state, send an retrieval request;

[0130] Receive location assistance information resent based on the acquisition request;

[0131] Based on the reissued positioning assistance information, a positioning measurement is performed;

[0132] Report the measurement results of the aforementioned positioning measurement.

[0133] In some embodiments, the method further includes:

[0134] In response to the failure of the location assistance information, a random access request is initiated, wherein the random access request carries indication information for obtaining the location assistance information;

[0135] Receive a random access response returned based on the random access request, wherein the random access response carries redistributed location assistance information;

[0136] Based on the reissued positioning assistance information, a positioning measurement is performed;

[0137] While maintaining the non-RRC idle state, the measurement results of the positioning measurement are reported during the random access process.

[0138] For example, the failure of the positioning assistance information includes: the time when the positioning request is received is not within the effective time range, and / or the UE is located outside the effective control range when the positioning request is received.

[0139] In this scenario, the UE still wants to maintain location measurements in the RRC disconnected state. The RRC disconnected state initiates a random access procedure. This random access procedure can be a 2-step or a 4-step procedure. In a 2-step procedure, the UE can include an instruction to reacquire location assistance information in the random access message (MsgA). Upon receiving Msg A, the base station will resend the location assistance information to the UE, and simultaneously, the base station and / or the UE will terminate the random access procedure. In a 4-step procedure, the UE can include an instruction to reacquire location assistance information in the random access message (Msg1 or Msg3). Upon receiving Msg2 or Msg4, the base station will resend the location assistance information to the UE, and simultaneously, the base station and / or the UE will terminate the random access procedure. By prematurely terminating the random access procedure, the UE will remain in the RRC disconnected state, thus avoiding switching to the high-power-consuming RRC connected state, reducing UE power consumption, and extending UE standby time.

[0140] like Figure 5A As shown, this embodiment provides a positioning method, which is applied in a base station, and the method includes:

[0141] S210: Send a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; wherein the positioning assistance information is used by the User Equipment (UE) to perform positioning measurements in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0142] When the UE is in RRC disconnected state, the UE may receive a location request or may not receive a location request. However, if the UE receives the location request while in RRC disconnected state, it can obtain a location result based on the location assistance information.

[0143] Therefore, as Figure 5B As shown, the method further includes:

[0144] S220: Receive the positioning result obtained from the positioning measurement based on the positioning assistance information.

[0145] In this embodiment, when the base station sends an RRC release message to the UE, it also simultaneously carries positioning assistance information. Thus, after receiving the RRC release message, the UE switches from RRC connected state to RRC disconnected state based on the message. Furthermore, when the UE receives a positioning request in RRC disconnected state, it performs positioning measurements based on the positioning assistance information. The base station then receives the positioning result obtained by the UE based on the positioning measurement performed by the UE in the positioning request.

[0146] In some embodiments, the method further includes:

[0147] The system receives a location request from the LMF (Location Assistance Message); and broadcasts the location request to the UE in a paging message. The location result is the location result obtained and reported by the UE based on the measurement of the location assistance information after receiving the paging message with the location request.

[0148] In some embodiments, S220 may include:

[0149] Receive the positioning result obtained by positioning measurement based on the positioning assistance information when the positioning assistance information is valid.

[0150] The positioning assistance information has a certain time validity and / or effective spatial range, and the positioning result is obtained based on the effective positioning assistance information.

[0151] For example, the effective positioning assistance information includes:

[0152] The current time is within the valid time range of the positioning assistance information;

[0153] and / or

[0154] The UE is located within the effective spatial range of the positioning assistance information.

[0155] In some embodiments, the current time being within the effective time range of the positioning assistance information includes: the current time being within the timing period of a timer started by the UE.

[0156] The UE being located within the effective spatial range of the positioning assistance information includes: the cell where the UE is camped is a cell included in the effective spatial range. The cells included in this effective spatial range can be indicated by cell IDs contained in the cell ID list.

[0157] In some embodiments, the method further includes: receiving a positioning result obtained by positioning measurement after the UE switches to RRC connected state when the positioning assistance information is invalid.

[0158] In some embodiments, the method further includes: receiving an acquisition request sent after the UE switches to the RRC connected state;

[0159] Based on the acquisition request, the location assistance information is resent;

[0160] The receiving of the positioning result obtained after the UE switches to RRC connected state when the positioning assistance information is invalid includes:

[0161] The UE receives the positioning result obtained by positioning measurement based on the re-sent positioning assistance information in RRC connected state when the positioning assistance information is invalid.

[0162] In some embodiments, the method further includes:

[0163] Receive a random access request sent by the UE when the positioning assistance information is invalid, wherein the random access request carries indication information for obtaining the positioning assistance information;

[0164] The random access response returned by the random access request includes, wherein the random access response carries redeployed location assistance information.

[0165] Receive the positioning result obtained based on the re-issued positioning assistance information.

[0166] For example, the positioning assistance information includes at least one of the following:

[0167] The measurement configuration of the positioning reference signal is at least used to indicate the resource location of the positioning reference signal;

[0168] The cell public parameter configuration is used to configure the public channel for locating and measuring the cell to be measured;

[0169] Valid time range indication information is used to indicate the valid time range of the positioning assistance information;

[0170] Effective spatial range indication information is used to indicate the effective spatial range of the positioning assistance information.

[0171] In some embodiments, the connection release message includes:

[0172] The first information unit (IE) carries indication information that instructs the UE to switch from RRC connected state to RRC disconnected state;

[0173] and / or

[0174] The second IE carries the aforementioned positioning assistance information.

[0175] For example, for UEs in RRC idle state or RRC inactive state, positioning assistance information can be obtained by reading positioning system messages or actively requesting the base station to broadcast positioning system messages. However, this implementation method has the problem of excessive system overhead and increased positioning latency.

[0176] This application provides a method for configuring positioning assistance information for a UE in an RRC idle or RRC inactive state. Specifically, the base station pre-configures positioning assistance information for the UE during the transition from an RRC connected state to an RRC idle or RRC inactive state. The UE uses this pre-configured positioning assistance information while in the RRC idle or RRC inactive state. During positioning measurements, when the UE transitions from an RRC connected state to an RRC idle or RRC inactive state, the serving base station configures positioning assistance information in an RRC Release message. This positioning assistance information is used for positioning measurements when the UE transitions to the RRC idle or RRC inactive state. The content of the positioning assistance information sent via the RRC Release message includes the following:

[0177] Location measurement auxiliary information mainly includes the information required for different positioning technologies to perform location measurements, such as the configuration of positioning reference information for the serving cell and neighboring cells, and the configuration of common cell parameters, etc.

[0178] The effective time range indication information for location assistance information is used to indicate to the UE the effective time of the location assistance information. For example, it can be a timer; if the timer expires, the location assistance information becomes invalid.

[0179] The effective spatial range indication information of the positioning assistance information is used to indicate the effective range of the positioning assistance information for the UE. For example, it can be a set of cell IDs.

[0180] Specifically, an IE can be added to the RRC Release message to represent the aforementioned location assistance information; or for UEs that have switched to the RRC inactive state, a new IE can be added to the SuspendConfig IE in the RRC release message to represent the aforementioned location assistance information.

[0181] When the UE is in RRC idle state or RRC inactive state, if the UE receives a location request from the network, based on the location assistance information received in the aforementioned RRC Release message, if the timer has not expired and the cell where the UE is located is within the effective range of the location assistance information, the UE completes the measurement required for location based on the location assistance information and reports the measurement results or location information.

[0182] When the UE is in RRC idle state or inactive state, if it receives a location request from the network, based on the location assistance information received in the aforementioned RRC release message, if the timer has not expired or the cell where the UE is located is outside the effective range of the location assistance information, the UE initiates random access, enters RRC connected state, requests location assistance information in RRC connected state, completes the measurements required for location, and reports the measurement results or location information.

[0183] When a UE transitions from an RRC idle or RRC inactive state to an RRC connected state for any reason, such as due to the failure of location assistance information, and then transitions back to an RRC idle or RRC inactive state, if the UE has a location requirement, the base station updates the UE's location assistance information by configuring location assistance information through an RRC release message. This location requirement can be determined by whether a location request issued by the LMF is responded to. If there is a response, it indicates a location requirement; otherwise, there is no location requirement.

[0184] When the UE transitions from RRC connected state to RRC idle state or RRC inactive state, the base station sends a new IE to the UE via an RRC release message to configure positioning assistance information.

[0185] Define the UE's behavior after receiving the above message. When the UE receives a location request in the RRC idle state or RRC inactive state, it first determines whether the location assistance information is valid. If it is valid, it performs location measurement. If it is invalid, it switches to the RRC connected state to reacquire the location assistance information.

[0186] like Figure 6 As shown, this embodiment provides a positioning device, which is applied in a user equipment (UE). The device includes:

[0187] The first receiving module 610 is configured to receive a Radio Resource Control (RRC) release message, wherein the RRC release message carries positioning assistance information; the positioning assistance information is used by the UE to perform positioning measurements and obtain positioning results in the RRC disconnected state; the RRC disconnected state includes: RRC idle state and RRC inactive state.

[0188] In some embodiments, the apparatus further includes: a positioning module 620, configured to perform positioning measurements based on the positioning assistance information in response to the UE receiving a positioning request in an RRC disconnected state, wherein the RRC disconnected state includes: an RRC idle state and an RRC inactive state;

[0195] In some embodiments, the positioning module 620, in response to the UE receiving the positioning request in the RRC disconnected state, determines that the positioning assistance information is valid if the timer used to time the valid time range has not expired; or, if the locator times out, determines that the positioning assistance information is invalid. For example, the positioning module 620 is configured to, in response to the UE receiving the positioning request in the RRC disconnected state, determine whether the timer used to time the valid time range at the current time has expired; if the timer has not expired, determine that the positioning assistance information is valid; or, if the locator times out, determine that the positioning assistance information is invalid.
