[0002] In the prior art, when a terminal has a need to transmit positioning data, it usually needs to enter a connected state first and transmit the positioning data through an established data radio bearer (DRB). That is, in the current solution, positioning data is only reported when the terminal is in a connected state. In this case, since the establishment of the terminal's connection state and the establishment of the DRB require a large amount of signaling interaction to be realized, it will result in the inability to efficiently transmit positioning data. Summary of the invention

Among them, the terminal 11 can also be called a terminal device or a user terminal (User Equipment, UE), and the terminal 11 can be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (Vehicle User Equipment, VUE), a pedestrian terminal (Pedestrian User Equipment, PUE) and other terminal side devices, and the wearable device includes: a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary. It should be noted that in the embodiment of the present application, only the base station in the NR system is taken as an example, but the specific type of the base station is not limited.

[0033] In order to facilitate understanding of the present application, the following contents are first explained.

[0034] Radio Bearer (RB) is a general term for a series of protocol entities and configurations allocated by gNB to UE. RB includes Signaling Radio Bearer (SRB) and Data Radio Bearer (DRB). SRB is the channel for the actual transmission of signaling messages of the system, and DRB is the channel for the actual transmission of user data. SRB types include SRB0, SRB1 and SRB2.

[0035] Radio Resource Control (RRC) is a protocol entity that manages RBs. It completes the establishment, modification, and release of RBs through the interaction of RRC signaling. Specifically, the RRC connection refers to the SRB1 established between the UE and the gNB. SRB0 is the default bearer and does not need to be established. The UE can obtain the configuration and resources of SRB0 when it is in the RRC idle state, that is, RRC_IDLE. The process of service initiation in the system is to establish SRB1 through signaling transmitted on SRB0. After SRB1 is established, the UE enters the RRC_Connected state; then, SRB2 is established through signaling transmitted on SRB1 to transmit NAS messages; DRBs are established using SRB1 transmission signaling to transmit user data, and are managed by SRB1 during the service process; when the service is completed, the signaling transmitted on SRB1 can release all DRBs and SRBs, so that the UE enters the RRC_IDLE state. When needed, the only resource that the UE can use is SRB0. SRB0 and SRB1 are used for the transmission of RRC messages. SRB1 may carry the configuration information of SRB2.

[0036] According to statistics on LPP (LTE Positioning Protocol) messages used to transmit positioning data, the length of positioning data is generally in the range of 16 to 414942 bits. The positioning measurement result is much larger than the length of the positioning position report, and the length of the report is related to the number of reported neighboring cells and the selected reporting format. The length of pure positioning data is generally less than 500 bits. And according to the conclusions of the current protocol, the range of small data that can be transmitted by LTE using the Early Data Transmission (EDT) method is between 328 and 1000 bits. Based on this, it is estimated that the small data transmission of 5G is also within this range, that is, the maximum transmission load of SRB can be greater than 500 bits. Therefore, SRB can be used to transmit positioning data.

[0037] For small data transmission, the characteristic of efficient small data transmission is that for non-connected UEs, such as IDLE and INACTIVE UEs, the excessive signaling overhead caused by the RRC state transition and RRC connection establishment process is avoided, and the purpose of small data transmission is achieved through a very simple signaling process. The characteristic of the small data transmission solution is that the current DRB of the UE is in a suspended state, not a released state. Therefore, before sending a resume request (Resume Request) message, the UE can resume the DRB first, and then use RRC signaling to carry small data. At this time, data can be transmitted on the DRB like a CONNECTED UE, thereby avoiding RRC state transition and achieving the purpose of efficient small data transmission with less signaling overhead.

[0038] The following describes in detail the positioning data sending method and receiving method provided by the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0039] See also Figure 2 , Figure 2 is a flowchart of a method for sending positioning data provided by an embodiment of the present application, the method is executed by a terminal, such as Figure 2 As shown, the method comprises the following steps:

[0040] Step 21: Get positioning data.

[0041] In this embodiment, the positioning data can be obtained through the positioning measurement process of the terminal. However, this application does not limit the positioning measurement method of the terminal, and the existing method can be used.

[0042] Optionally, the positioning data in the embodiments of the present application may include but is not limited to at least one of the following: positioning measurement information, position information, event information, positioning request information, differential position information, differential measurement information, etc.

[0043] Step 22: When the terminal is in an idle state or an inactive state, SRB0 or ​​SRB2 is used to send positioning data.

[0044] In this embodiment, SRB0 is the default bearer, and the terminal can obtain the configuration and resources of SRB0 when it is in the RRC idle (IDLE) state or the inactive (INACTIVE) state. Therefore, when the terminal is in the idle state or the inactive state, it can use SRB0 to send positioning data. Usually, SRB2 is established after SRB0. SRB2 is specifically used to transmit Non-Access Stratum (NAS) messages. There is an uplink data type in the NAS messages, which contains various service messages, and one of them is the positioning message. In this embodiment, SRB0 and SRB2 can be established in the same step to achieve the purpose of sending positioning data in the idle state and the inactive state.

[0045] An implementation manner is as Figure 3 shown. When the UE is in the IDLE state, it can send positioning data to the gNB through a new RRC message such as the RRCPosRequest message. This new RRC message carries the NAS container NAScontaner, which contains the positioning data and is transmitted on SRB0. After receiving the positioning data, the gNB directly sends it to the Access and Mobility Management Function (AMF) and forwards it to the Location Management Function (LMF).

[0046] In another implementation manner, when the UE is in the connected state and receives an RRC release message sent by the network-side device, which indicates that SRB2 is supported to send positioning data in the INACTIVE state and includes the SRB2 configuration information in the INACTIVE state. The SRB2 configuration information includes RB ID, logical channel mapping relationship, logical channel priority, feedback mode, etc. Then, the UE performs positioning measurement in the INACTIVE state. The UE sends positioning data in the INACTIVE state through the RRC resume message and SRB2, multiplexed on one MAC PDU.

[0047] In another implementation manner, when the UE is in the connected state and receives an RRC release message sent by the network-side device, which indicates that the network configures the positioning data length threshold value P to be equal to 1000. When the actual length L of the positioning data is less than P, it is transmitted in the SRB0 manner, and when L≥P, it is transmitted in the SRB0 manner. Then, the UE performs positioning measurement in the INACTIVE state. When the length of the positioning data to be reported by the UE is 2000, that is, greater than P, the UE sends the positioning data in the INACTIVE state through the RRC resume message and SRB2, multiplexed on one MAC PDU.

[0048] Another implementation method, such as Figure 4 As shown, in the INACTIVE state, the UE can send positioning data to the gNB through an RRC recovery request (such as RRCResumeRequest) message. The RRCResumeRequest message carries a dedicated NAS message, which contains positioning data and is transmitted on SRB0. After receiving the dedicated NAS message, the gNB directly sends it to the AMF and forwards it to the LMF. In addition, the dedicated NAS message can also be transmitted on SRB2.

[0049] For SRB0 and SRB2: Since SRB0 is a one-time transmission, using SRB0 to send positioning data can save resources; and SRB2 supports segmented transmission, so when the positioning data is too large, SRB2 can be used for segmented transmission.

[0050] In the positioning data sending method of the embodiment of the present application, after the terminal obtains the positioning data, it can use SRB0 or ​​SRB2 to send the positioning data when it is in an idle state or an inactive state. In this way, the positioning data transmission of the terminal in an idle state or an inactive state can be realized, and there is no need for the terminal to transmit the positioning data through DRB after entering the connected state, thereby realizing efficient transmission of positioning data.

[0051] In the embodiment of the present application, the terminal can send positioning data in the form of small data transmission in the IDLE state or INACTIVE state. Optionally, without entering the connected state, the terminal can send positioning data in SRB0 or ​​SRB2 when at least one of the following conditions is met:

[0052] 1) The terminal receives the resource for small data transmission configured by the network side and the parameter configuration information associated with the resource. For example, the resource for small data transmission may include 4-step / 2-step random access small data transmission (SDT) resources, SDT configuration authorization CG resources, etc. The parameter configuration information includes the data size that the resource can carry, etc.

[0053] 2) The transmission length of the positioning data is less than a first threshold. The first threshold can be set based on actual needs. For example, the first threshold is the maximum length of uplink data that can be sent by the terminal in the IDLE / INACTIVE state.

[0054] 3) NAS triggers RRC connection establishment or RRC connection recovery due to the transmission of positioning data.

[0055] In one implementation, when the terminal uses SRB2 to send positioning data, it can directly send an uplink information transfer (such as ULInfomationTransfer) message carrying a NAS container (container) through SDT CG resources, and load the positioning data in the NAScontainer.

[0056] As an optional embodiment, when the terminal is in an inactive state, SRB0 or ​​SRB2 is used to send positioning data, and SRB2 is used by default to send positioning data, that is, SRB2 is the default bearer type. For the SRB2 solution, before the terminal sends UL data, SRB1 and SRB2 are restored first.

[0057] As an optional embodiment, when the terminal is in an idle state, SRB0 is used to send positioning data.

[0058] Optionally, when the terminal uses SRB0 to send positioning data, the positioning data may be encapsulated in a service data unit (SDU) of an uplink common control channel (CCCH) and sent.

[0059] Optionally, when the terminal uses SRB2 to send positioning data, the positioning data may be mapped to a dedicated control channel (Dedicated Control Channel, DCCH) for transmission.

[0060] In the embodiment of the present application, in order to send positioning data, the terminal may obtain RB configuration information, and send the positioning data according to the obtained RB configuration information. For example, the RB configuration information may be carried by an RRC release message.

[0061] Optionally, the RB configuration information may include but is not limited to at least one of the following:

[0062] a) SRB type

[0063] The SRB type may also be referred to as an SRB identifier. The SRB type may be, for example, SRB0 or ​​SRB2. With the SRB type included in the RB configuration information, the network side may specify the SRB type as SRB0 or ​​SRB2 through explicit configuration to instruct the terminal to adopt the corresponding SRB configuration when sending positioning data, and the corresponding SRB may be used to send uplink data.

[0064] b) SRB configuration information

[0065] Optionally, the SRB configuration information may include but is not limited to at least one of the following:

[0066] i. Packet Data Convergence Protocol (PDCP) configuration information: The PDCP configuration information may indicate the compression method, encryption algorithm, etc. of the positioning data, so that the terminal may process the positioning data using the corresponding compression method, encryption algorithm, etc.

[0067] ⅱRLC mode: This RLC mode can indicate whether the transmission of positioning data requires ACK / NACK feedback. The RLC mode includes three modes: unreliable mode UM, reliable mode AM and transparent transmission mode TM. UM does not require feedback, AM requires feedback, and TM is transparent transmission without any processing. Through the RLC mode included in the SRB configuration information, the terminal can be used to know whether the transmission of the corresponding positioning data requires feedback.

[0068] ⅲRLC configuration information: The RLC configuration information is used to locate the transmission reliability of data, including RLC segment length, cascade configuration, retransmission time, etc.

[0069] iv. Logical channel identifier: This logical channel identifier is related to the priority of the positioning data and can be used to enable the positioning data to be sent with high priority.

[0070] v. Logical channel configuration information: The logical channel configuration information may include logical channel priority, mapping relationship between logical channels and physical channels, etc., which is used by the terminal to send positioning data based on the logical channel configuration information.

[0071] Optionally, the terminal can obtain RB configuration information by any of the following methods:

[0072] RRC release message; that is, the RB configuration information may be released by an RRC release message;

[0073] Broadcast message; that is, the RB configuration information may be carried by the broadcast message;

[0074] Paging message; that is, the RB configuration information may be carried by a paging message. For example, in an MT positioning scenario, the RB configuration information may be indicated by a paging message.

[0075] In the embodiment of the present application, the choice of whether the terminal uses SRB0 or ​​SRB2 to send positioning data can be determined by any of the following methods:

[0076] (1) Network explicit indication

[0077] In this (1), the network side device can specify the SRB type as SRB0 or ​​SRB2 by explicit configuration, or indicate the mapping relationship between the SRB type and the positioning data transmission, to instruct the terminal to use the corresponding SRB configuration when sending the positioning data, and the corresponding SRB will send the positioning data.

[0078] Optionally, the terminal may receive first indication information from the network side device, where the first indication information is used to indicate whether the positioning data is supported to be sent under SRB0 or ​​SRB2. That is, the network side device may explicitly indicate whether the positioning data is supported to be sent under SRB0 or ​​SRB2 (yes / no), so that the terminal selects SRB to send the positioning data accordingly.

[0079] (2) Network Implicit Indication

[0080] For implicit network indication, 1) the network side device can configure the data transmission characteristics under SRB0 and / or SRB2. The terminal can receive the data transmission characteristics under SRB0 and / or SRB2 from the network side device, and determine which SRB to use to send positioning data based on the characteristics. The data transmission characteristics may include but are not limited to at least one of the following:

[0081] i. Transmission length: The transmission length can be selected as the number of bits that can be carried. For example, when the number of bits is not enough to carry the positioning data and segmentation is required, SRB2 must be used.

[0082] ⅱTransmission rate: The transmission rate corresponds to the Quality of Service (QoS). For example, SRB0 and SRB2 map different QoS respectively. Depending on the QoS, you can choose to use SRB0 or ​​SRB2 to transmit positioning data.

[0083] ⅲ Transmission priority: The network side device can configure the transmission priority of SRB0 and / or SRB2 so that the terminal can select the SRB for transmitting positioning data accordingly.

[0084] iv. Transmission delay: The network side device can configure the transmission delay of SRB0 and / or SRB2 so that the terminal can select the SRB for transmitting positioning data accordingly. For example, compared with SRB2, the transmission delay of SRB0 is smaller.

[0085] In one implementation, the UE may select SRB0 or ​​SRB2 to send positioning data based on a comparison result between the current positioning service requirement and the data transmission characteristics under the SRB.

[0086] 2) The network side device and the terminal can pre-agree on the default SRB type for sending positioning data, so that the terminal uses SRB0 or ​​SRB2 to send positioning data according to the pre-agreement between it and the network side device. This pre-agreement can be implemented by the terminal capability or by reconfiguring the signaling process.

[0087] 3) For INACTVE terminals, if the network side configures resources for small data transmission (for example, 4-step / 2-step SDT resources, SDT CG resources, etc.) or the network side indicates that the current cell supports small data transmission, the terminal selects SRB2 to send positioning data.

[0088] (3) Terminal Capability Indication

[0089] In this (3), the terminal can report capability information to the network side device, and this capability information is used to indicate the SRB type supported by the terminal for sending positioning data. That is, the terminal can report to the network side device which SRB type is supported for sending positioning data, and then the network side device performs explicit or implicit SRB configuration on the terminal according to the SRB type reported by the terminal.

[0090] (4) Terminal preference indication

[0091] In this (4), the terminal can send preference indication information to the network side device; the preference indication information is used to indicate the SRB type preferred by the terminal when it is in an idle state or an inactive state. That is, the terminal can report the SRB type preferred by the terminal in an idle state or an inactive state to the network side device, for example, it can be reported together with the on demand information reporting.

[0092] (5) Agreement

[0093] In this case (5), the terminal can use SRB0 or ​​SRB2 to send positioning data according to the protocol agreement.

[0094] For example, when the positioning data reported by the UE includes certain (such as positioning measurement information) or several types of positioning information, SRB2 is used for reporting, otherwise SRB0 is used for reporting.

[0095] For another example, when the amount of positioning data (such as the number of bits) reported by the UE is higher than threshold 1, SRB2 is used for reporting; and / or, when the amount of data (such as the number of bits) reported by the UE exceeds threshold 2, the UE enters the connected state for reporting.

[0096] In an embodiment of the present application, when the transmission length of the positioning data to be sent is greater than the second threshold, the terminal may use SRB2 segmentation to send the positioning data. The second threshold may be set based on actual needs. For example, when the transmission length of the positioning data to be sent by the UE is greater than the maximum transmission length configured by SRB, the positioning data may be segmented, and the positioning data may be sent by SRB2 segmentation by default.

[0097] Optionally, in order to ensure the security of positioning data, when the terminal uses SRB2 to send positioning data, the positioning data needs to be securely encrypted. For example, the securely encrypted key information can be carried by the RRC release message, or carried by the sent SMC message and stored in the UE memory.

[0098] Optionally, when there is a need to send positioning data, the terminal can set the recovery reason value to positioning data sending at the same time when initiating the RRC recovery request process, and establish SRB0 and / or SRB2 according to the network pre-configuration information to send positioning data. When initiating the RRC recovery request process, the terminal can also start the positioning data sending timer T, so that when the timer T times out and the positioning data is not sent, it enters the connected state to send the positioning data through the DRB.

[0099] Optionally, after using SRB0 or ​​SRB2 to send the positioning data, the terminal may release the RB resources and return to the inactive state after receiving an acknowledgment response ACK from the network side device.

[0100] Optionally, after using SRB0 or ​​SRB2 to send positioning data, the terminal can use SRB0 or ​​SRB2 to retransmit the positioning data after receiving a negative response NACK from the network side device or the positioning transmission timer times out, or send the positioning data by entering a connected state. For example, the connected state of the terminal can be achieved by initiating an RRC connection establishment process.

[0101] In the embodiment of the present application, in addition to using SRB0 or ​​SRB2 to send positioning data, SRB0 or ​​SRB2 may also be used to send other information, such as sending at least one of the following:

[0102] REGISTRATION REQUEST;

[0103] Uplink transmission data (UL NAS TRANSPORT);

[0104] Deregistration request (DEREGISTRATION REQUEST);

[0105] Service request or business request (SERVICE REQUEST);

[0106] Protocol Data Unit (PDU) session context establishment request (PDU SESSIONESTABLISHMENT REQUEST);

[0107] PDU SESSION MODIFICATION REQUEST;

[0108] PDU session release request (PDU SESSION RELEASE REQUEST);

[0109] Status information of the service management module (such as 5GSM STATUS).

[0110] Furthermore, the above-mentioned uplink transmission data may include at least one of the following:

[0111] Service management module information (such as N1 SM information);

[0112] Text messages (SMS);

[0113] Positioning data container (such as LTE Positioning Protocol (LPP) message container);

[0114] SOR transparent container;

[0115] UE policy container;

[0116] UE parameters update transparent container;

[0117] Location services message container;

[0118] CIoT user data container;

[0119] Multiple payloads.

[0120] In one implementation, when the positioning data transmission conflicts with other data, the data can be processed according to the priority of each data, such as sending the data with a higher priority first.

[0121] In another embodiment, when using SRB2 to send positioning data, if the positioning data conflicts with deregistration, the deregistration process is prioritized; if the positioning data transmission conflicts with a service request operation, the service request process is prioritized; and if the positioning transmission conflicts with non-UL NAS transport, the sending of the positioning data is prioritized.

[0122] In an embodiment of the present application, the terminal may send positioning data indication information to the network-side device, and the positioning data indication information is used to indicate that the data sent by the terminal is positioning data, so that the network-side device can know that the data sent by the terminal is positioning data. For example, the positioning data indication information may be a positioning data indication identifier, or the positioning data indication information may be a resumeCause value, which is explicitly included in the RRC resume message.

[0123] Optionally, the terminal may also determine the data type of the positioning data according to the mapping relationship between the SRB type and the data type, that is, in this embodiment, a mapping relationship may be established based on the SRB type / identifier, and the type of the positioning data sent is implicitly indicated by the RBID.

[0124] Optionally, the terminal may receive positioning priority indication information from the network-side device, and the positioning priority indication information is used to indicate that the priority of the positioning data is higher than that of other data. For example, the network-side device may broadcast or set a positioning priority indication identifier in the RRC release message, and true indicates that the positioning data has a higher priority than other data for sending in the INACTIVE state, and is used only by positioning terminals and / or positioning-sensitive terminals.

[0125] Optionally, when using SRB0 or SRB2 to send positioning data, the terminal may select SRB0 or SRB2 to send the positioning data based on the transmission length of the positioning data. When the transmission length of the positioning data is less than a third threshold, the terminal may use SRB0 to send the positioning data; or when the transmission length of the positioning data is greater than or equal to the third threshold, the terminal may use SRB2 to send the positioning data. The third threshold may be set according to actual requirements, such as the maximum data transmission length on SRB0.
