Description

Technical Field

[0001] This invention relates to the field of wireless technology, and in particular to a terminal positioning method, apparatus, terminal, and network-side equipment. Background Technology

[0002] When the UE is in a deactivated state, after the Access and Mobility Management Function (AMF) receives a location service request, the AMF triggers a service request on the network side to establish / activate a signaling connection with the UE. When the UE is in an idle state, a specific serving gNB or ng-eNB also needs to be assigned. Before the location procedure begins, it is assumed that the UE has already entered a connected state; that is, before triggering the initial steps of the location procedure, any signaling may be needed to switch the UE to a connected state. During the location operation, the established signaling connection may subsequently be released by the NG-RAN due to inactivity of signaling and data.

[0003] Current location services only support UEs in a connected state. For example, terminals in factories or shopping malls need periodic location services, even though they have no other business requiring them to remain in a connected state or periodically switch to a connected state with the location cycle. Since these terminals mainly use location services and rarely have data services, and the process of switching a deactivated UE to a connected state introduces high latency, implementing location services for deactivated terminals could effectively reduce terminal power consumption and location service latency. Summary of the Invention

[0093] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0094] To address the issue that existing technologies require inactive terminals to switch to connected mode to enable location services, resulting in high terminal power consumption and location service latency, this invention provides a terminal positioning method. In an inactive state, the terminal can obtain downlink positioning reference signal configuration information from network-side equipment. While inactive, it can perform positioning measurements based on this configuration information, ensuring that the terminal can still provide location services after entering an inactive state.

[0095] It should be noted that the terminal positioning method described in this embodiment of the invention can be applied to one of the following: Network Induced Location Request (NI-LR) service, Mobile Terminated Location Request (MT-LR) service, and Mobile Originated Location Request (MO-LR) service initiated by the UE and originating from the terminal.

[0096] Taking the location service triggered by the Access and Mobility Management function (AMF) unit in NI-LR and MT-LR starting with the Location Management Function (LMF) as an example, Figure 1 As shown, after receiving a location service request for a target UE, the AMF unit will send the location service request to the LMF unit. The LMF processes the location service request using Long Term Evolution Positioning Protocol (LPP) message transmission and New Radio Positioning Protocol A (NRPPa) transmission, which may include forwarding auxiliary data to the target UE to assist in UE-based and / or UE-assisted positioning, and / or sending the target UE's location to the location requester. The LMF then returns the location service result (e.g., the UE's predicted location) to the AMF. In cases where other entities besides the AMF (e.g., the UE, LCS customers) send the request, the AMF will also return the location service result to those entities.

[0097] Additionally, for MO-LR services, the process begins when a customer on the UE or user requests some location services, such as reading the UE's location or transmitting the UE's location to a third party. The specific procedures vary and require further explanation.

[0098] The location services in the above implementation processes only support location services in the connected state. When the UE is in the deactivated state, the AMF will trigger a service request on the network side to establish / activate a signaling connection with the UE. Before triggering the initial steps of the location process, a signaling is required to convert the UE to the connected state. Therefore, the process of converting the UE to the connected state will cause a high latency problem.

[0099] To address the aforementioned issues, this invention provides a terminal positioning method. When the terminal is in an inactive state, the network-side device can send configuration information of the downlink positioning reference signal to the terminal via preset signaling. This enables the terminal to obtain the configuration of the downlink positioning reference signal in the inactive state and perform positioning measurements, avoiding the need to enter the connected state, which results in high terminal power consumption and high positioning service latency.

[0100] One embodiment of the present invention provides a terminal positioning method, executed by the terminal, such as... Figure 2 As shown, the method includes:

[0101] S210, when the terminal is inactive, it obtains the configuration information of the downlink positioning reference signal sent by the network-side device;

[0102] S220, perform positioning measurement according to the configuration information.

[0103] Using the terminal positioning method described in this embodiment, when the terminal is inactive, it can obtain the configuration information of the downlink positioning reference signal sent by the network-side device through preset signaling, and realize positioning measurement in the inactive state according to the configuration information.

[0104] Optionally, in step S210, the configuration information of the downlink positioning reference signal sent by the network-side device may include one or more sets of downlink positioning reference signal configurations.

[0105] Optionally, the configuration information of the downlink positioning reference signal includes an index of the corresponding downlink positioning reference signal configuration and / or a timer for the validity period of the indicated downlink positioning reference signal configuration.

[0106] Further, optionally, in step S210, configuration information of downlink positioning reference signals shared by multiple terminals sent by the network-side device can be obtained through preset signaling, or configuration information of downlink positioning reference signals specific to the terminal sent by the network-side device can be obtained.

[0107] Optionally, the preset signaling can be at least one of the following: a message during random access, an RRC release message, a system message, a paging message, and a multicast message.

[0108] In one implementation, optionally, configuration information of downlink positioning reference signals shared by multiple terminals sent by the network-side device is obtained through at least one of the following messages:

[0109] RRC release message;

[0110] System message;

[0111] Paging messages;

[0112] Multicast broadcast messages.

[0113] Optionally, configuration information of the downlink positioning reference signal specific to the terminal sent by the network-side device can be obtained through at least one of the following messages:

[0114] RRC release message;

[0115] Msg4 during the random access process;

[0116] Msg B during the random access process.

[0117] In this embodiment of the invention, optionally, in step S210, the step of obtaining the configuration information of the downlink positioning reference signal sent by the network-side device, the obtained configuration information includes an updated configuration based on the original downlink positioning reference signal configuration of the terminal, and / or includes the configuration of the latest received downlink positioning reference signal.

[0118] Using the terminal positioning method described in this embodiment of the invention, the configuration information of the downlink positioning reference signal sent by the network-side device to the terminal indicates the updated configuration of the original downlink positioning reference signal (such as the downlink positioning reference signal obtained in the connected state) and / or indicates the configuration of the newly received downlink positioning reference signal, so that the terminal can receive the downlink positioning reference signal in the inactive state using the updated configuration of the downlink positioning reference signal or the latest configuration of the downlink positioning reference signal for positioning measurement.

[0119] Optionally, the terminal positioning method described in this embodiment of the invention further includes:

[0120] When the terminal is inactive, it sends location-related information to the network-side device; the location-related information includes request assistance information and / or location measurement information.

[0121] Optionally, when the request for assistance information includes such information, the configuration information sent by the network-side device is determined based on the request for assistance information. That is, optionally, the network-side device sends the configuration information to the terminal based on the request for assistance information in the location-related information.

[0122] Optionally, the configuration information includes an updated configuration based on the original downlink positioning reference signal configuration of the terminal, and / or includes the configuration of newly added downlink positioning reference signals received by the terminal.

[0123] By employing this implementation method, the request assistance information in the positioning-related information is used to indicate the updated configuration of the original downlink positioning reference signal (such as the downlink positioning reference signal obtained in the connected state) and / or to indicate the configuration of the newly received downlink positioning reference signal, so that the terminal can receive the downlink positioning reference signal for positioning measurement in the inactive state by using the updated configuration of the downlink positioning reference signal or the latest configuration of the downlink positioning reference signal.

[0124] Optionally, when the terminal is inactive, it sends location-related information to the network-side device, including:

[0125] When the terminal is inactive and the current downlink positioning reference signal configuration does not meet the positioning requirements, it sends the positioning-related information to the network-side device.

[0126] Specifically, when the terminal is in an inactive state and the current downlink positioning reference signal configuration cannot meet the current positioning accuracy requirements and / or latency requirements, the terminal sends positioning-related information to the network-side device.

[0127] Optionally, sending location-related information to the network-side device includes:

[0128] The information sent to the network-side device is indicated to be location-related information by at least one of the following methods:

[0129] The location-related information includes N preset indication information; N is an integer greater than or equal to 1;

[0130] The destination address for receiving the location-related information is the Location Management Function (LMF) unit.

[0131] By employing this implementation method, by including N preset indication information in the location-related information and / or the destination receiving address as an LMF unit, when the network-side device receives information from the terminal, it can determine that the received information is location-related information.

[0132] Optionally, when sending location-related information to the network-side device, the location-related information may be sent to the network-side device in one of the following ways:

[0133] MsgA during random access;

[0134] Msg3 during the random access process;

[0135] Scheduling Request (SR);

[0136] Configure and authorize the resources specified in CG-config;

[0137] Preamble.

[0138] Optionally, when sending location-related information to the network-side device, the location-related information message is transmitted via a pre-configured synchronization signal and the first beam of the PBCH block SSB.

[0139] The configuration information is based on the downlink positioning reference signal corresponding to the first beam.

[0140] That is, optionally, the message used to send positioning-related information can be transmitted via the first beam, and optionally, the configuration information is a configuration based on the downlink positioning reference signal corresponding to the first beam, in which way the requested PRS configuration can be implicitly indicated to the base station.

[0141] Optionally, the configuration information is a configuration based on the downlink positioning reference signal corresponding to the first beam. It can be a predefined configuration of the downlink positioning reference signal related to the first beam, or it can be a configuration of the downlink positioning reference signal determined based on the first beam.

[0142] Optionally, in this embodiment of the invention, when sending positioning-related information to the network-side device through the first beam of the SSB, it is also used to instruct the terminal to receive the corresponding positioning reference signal on the first beam.

[0143] Using the terminal positioning method described in this embodiment, based on the above-mentioned use of N-bit preset indication information and / or destination receiving address as LMF unit, adding positioning-related indications to indicate that the information sent is positioning-related, the positioning-related information can be sent to the network-side device by displaying at least one of the following methods: MsgA in the random access procedure, Msg3 in the random access procedure, scheduling request SR, and configuration authorization CG-config. Alternatively, the positioning-related information can also be sent to the network-side device by implicit indication through the configured synchronization signal and the first beam of the PBCH block SSB.

[0144] Optionally, in this embodiment of the invention, the Msg A used to send location-related information can reuse the resources of random access based-small data transmission (RA based-SDT); the resources configured in the configuration grant CG-config used to send location-related information can be reused as resources of configured grant based-small data transmission (CG-based SDT).

[0145] It should be noted that when transmitting location-related information based on small packet transmission resources, although the resources transmitted in small packets are configured separately and it is impossible to distinguish whether they are used for location, the method described in this embodiment of the invention can be used to indicate that the transmitted information is location-related information by adding N bits of preset indication information and / or the destination receiving address as an LMF unit. This allows the base station to directly pass the location-related information to the LMF unit without parsing the specific information content in the location-related information.

[0146] The terminal positioning method of this invention, when transmitting the positioning-related information message via the first beam, further includes:

[0147] Positioning measurements are performed using the configuration of the downlink positioning reference signal corresponding to the first beam.

[0148] In this embodiment of the invention, the location-related information sent by the terminal to the network-side device can be sent through a Location Service (LCS) message, an LTE Positioning Protocol (LPP) message, or a Radio Resource Control (RRC) message.

[0149] Optionally, it may include auxiliary information requested by the terminal to the LMF, such as the terminal's requirements for positioning accuracy, latency, etc.; auxiliary information provided by the LMF to the UE, such as PRS configuration, PRS configuration index, SSB information of the Transmission Node (TRP), PCI, GCI, and TRPID for measuring one or more candidate TRPs, as well as measurement results and location estimation information sent from the terminal to the LMF.

[0150] Therefore, specifically, based on the type of location-related information, the request assistance information includes location requirement information, which includes, but is not limited to, only location accuracy requirement information and / or time delay requirement information.

[0151] In another implementation, the requested assistance information may include, but is not limited to, at least one of the following:

[0152] Beam switch request information;

[0153] A request to switch on / off the positioning reference signal;

[0154] Configure indexes;

[0155] Configuration of positioning reference signals;

[0156] Low battery indicator;

[0157] Number of base stations;

[0158] Number of nodes;

[0159] Location process start time;

[0160] Location result reporting time.

[0161] In one embodiment of the present invention, the requested assistance information may include positioning requirement information to indicate corresponding positioning-related requirements, such as accuracy requirement information and / or latency requirement information; in another embodiment, the requested assistance information may include specific positioning-related information requested, such as beam switching request, switching request for positioning reference signal, requested configuration index, requested PRS configuration (such as period, beam and bandwidth, etc.), low battery indication, desired or preferred number of base stations or nodes, desired or preferred positioning process start time and desired or preferred positioning result reporting time, or one or more of these.

[0162] In this embodiment of the invention, the terminal positioning method, in step S220, after performing positioning measurements according to the configuration information, further includes:

[0163] The measurement results obtained from the positioning measurement are reported to the network-side device through Msg3 or Msg A during the random access process.

[0164] Optionally, in this implementation, the terminal transmits the measurement results obtained from the positioning measurement to the base station via Msg3 or Msg A, and the base station transmits the measurement results to the LMF unit.

[0165] Using the terminal positioning method described in this embodiment of the invention, when the terminal is in an inactive state, the network-side device can send downlink positioning reference signal configuration information to the terminal through at least one of the following: messages during random access, RRC release messages, system messages, paging messages, and multicast broadcast messages. This enables the terminal to obtain the downlink positioning reference signal configuration in the inactive state and perform positioning measurements, avoiding the need to enter the connected state, which would otherwise cause high terminal power consumption and positioning service latency.

[0166] The following describes the terminal positioning method described in this embodiment of the invention by taking into account the specific implementation process during terminal positioning.

[0167] Implementation Method 1

[0168] like Figure 3 As shown, the terminal positioning method described in this embodiment of the invention may include the following steps in its specific implementation:

[0169] S310, the base station configures multiple sets of downlink positioning reference signals for terminals with different positioning needs, and when the terminal is released to enter the deactivation state, it sends the configuration information of multiple sets of downlink positioning reference signals to the terminal in advance through the RRC release message; optionally, the configuration information sent includes a timer for the effective time of the associated downlink positioning reference signal configuration and an index of the downlink positioning reference signal configuration;

[0170] S320: When the terminal determines that the current downlink positioning reference signal configuration does not meet the positioning requirements, it sends positioning-related information to the base station; optionally, it sends positioning-related information to the base station using Msg3 via small packet transmission.

[0171] In this embodiment, optionally, the location-related information includes N-bit preset indication information and / or a destination receiving address as an LMF unit, used to indicate that the transmitted information is location-related information, and optionally, the location-related information is also used to indicate the index of the downlink positioning reference signal configuration corresponding to the requirement, used to request an explicit downlink positioning reference signal configuration;

[0172] S330, the base station determines that the information is location-related information based on the N-bit preset indication information and / or the destination receiving address in the received information as an LMF unit, and then transmits the location-related information to the LMF unit.

[0173] S340, when the LMF unit decides to change the configuration of the downlink positioning reference signal corresponding to the requested index of the positioning-related information based on the configuration requirements of the positioning reference signal in the received positioning-related information, it sends the configuration update information of the downlink positioning reference signal to the base station.

[0174] S350, optionally, the base station can use Msg4 to transmit configuration update information to the UE via small packet transmission.

[0175] Optionally, the above implementation method further includes: the terminal receiving the configuration update information, receiving the downlink positioning reference signal using the updated configuration, performing positioning measurement, and obtaining the measurement result.

[0176] It should be noted that when there is a lot of configuration information and it cannot be transmitted in the deactivated state via small packets, it can be indicated by pre-configuring and adding an index.

[0177] Implementation Method 2

[0178] like Figure 4 As shown, the terminal positioning method described in this embodiment of the invention may include the following steps in its specific implementation:

[0179] S410, after the UE enters the deactivation state, the Location Services (LCS) user initiates MT-LR positioning service. However, due to energy-saving requirements, beam A in the existing downlink positioning reference signal configuration needs to be turned off. Therefore, positioning-related information is sent to the base station via Msg3 using small packet transmission. The positioning-related information includes the beam that needs to be turned off. Optionally, the positioning-related information includes N bits of preset indication information and / or the destination receiving address is an LMF unit.

[0180] S420, if the base station determines that the received information is location-related information, it will then transmit the location-related information to the LMF unit.

[0181] S430, when the LMF unit determines the request in the location-related information of the receiving terminal based on the location-related information, it sends the configuration update information of the downlink positioning reference signal to the base station.

[0182] S440, optionally, the base station can use Msg4 to transmit configuration update information to the UE via small packet transmission, and send downlink positioning reference signals with the configuration of turning off beam A.

[0183] S450, the terminal receives the configuration update information, uses the updated configuration to receive the downlink positioning reference signal, performs positioning measurement, obtains the measurement result, and reports the measurement result.

[0184] It should be noted that the above implementation process is only an example of the implementation process of the terminal positioning method described in the embodiments of the present invention, and is not limited to the above implementation process.

[0185] Another aspect of this invention provides a terminal positioning method, such as... Figure 4As shown, the method, executed by the network-side device, includes:

[0186] S510 sends configuration information for downlink positioning reference signals to terminals in an inactive state.

[0187] Using the terminal positioning method described in this embodiment, when the terminal is in an inactive state, the network-side device can send configuration information of downlink positioning reference signals to the network-side device through preset signaling. Based on the configuration information, the positioning measurement of the terminal in the inactive state can be realized, ensuring that the terminal can still provide positioning services after entering the inactive state.

[0188] In this embodiment of the invention, it should be noted that the network-side device can be a base station connected to the terminal, or it can be an LMF unit. When the network-side device is an LMF unit, it sends configuration information for downlink positioning reference signals to the terminal through the base station.
