Description

Technical Field

[0001] This application relates to the field of wireless communication, and in particular to a data interaction method, apparatus, communication device, and storage medium. Background Technology

[0002] The Location Management Function (LMF) is primarily responsible for supporting various location services for User Equipment (UE), including UE location positioning and sending assistance messages to the UE. The LMF entity may interact with the base station (gNB) to obtain location measurements of the UE, and may also interact with the UE to obtain assistance messages or estimated UE locations. To locate a target UE, the LMF entity can also select a positioning method based on the Location Measurement Service (LCS) client type, Quality of Service (QoS) requirements, and the positioning capabilities of the UE and gNB.

[0003] Long Term Evolution (LTE) Positioning Protocol (LPP) technology is used in point-to-point positioning between LMF entities and UEs. Its main purpose is to obtain the UE's location through positioning measurements from one or more reference sources. LPP sessions are used between LMF entities and UEs, primarily for acquiring relevant location measurements, location estimates, or transmitting auxiliary data.

[0004] In related technologies, when an LMF entity sends location measurement information to a base station, it may not know the size of the data packet that the base station is compatible with, resulting in mismatch between the reported location measurement information and the data packet, or the location measurement information may be too small, leading to a waste of transmission resources.

[0120] The present invention will be further described in detail below with reference to the embodiments, starting with a description of the relevant technologies.

[0121] As mentioned above, an LPP session is used between the LMF entity and the UE, primarily for acquiring corresponding location measurements, location estimations, or transmitting auxiliary data. One LPP session mainly supports a single location request, while multiple LPP sessions can correspond to different location requests between two nodes. Each LPP session contains one or more LPP transactions, each performing an operation, such as location capability interaction, auxiliary data transmission, or location information transmission. A transaction ID (transaction identity document) can be used to associate a set of LPP transaction messages. Each LPP transaction may contain one or more LPP message exchanges between the LMF and the terminal. The LPP session process is as follows: Figure 1 As shown, it includes the following steps:

[0122] 1. Node A initiates an LPP session by sending LPP messages to Node B during an LPP transaction.

[0123] 2. Node A and Node B can further exchange messages to continue the transaction that started in step 1;

[0124] 3. Any node can initiate a new transaction by sending additional LPP messages;

[0125] 4. The LPP session is terminated by transaction N.

[0126] LPP messages enable the exchange between two nodes.

[0127] LPP segmentation is primarily used when the size of an LPP message exceeds the maximum processing capacity supported by the underlying protocol stack. In this case, an LPP message body can be divided into several shorter LPP messages for transmission. When the sender uses LPP segmentation, it should include a SegmentationInfo IE in each LPP message segment to indicate whether the message is one of several LPP message segments other than the last one. When the receiver receives an LPP message with the same session ID and transaction ID as a previous message, if the message indicates that more identical messages are being transmitted, the receiver will store the current message; if the message indicates that no more messages are being transmitted, the receiver will consider the segmentation complete and begin processing LPP messages with the same session ID and transaction ID.

[0128] In inactive positioning, Small Data Transmission (SDT) can be used to send measurement reports and location estimates, offering advantages such as lower signaling overhead, lower latency, and more flexible uplink data transmission timing. Before executing the SDT procedure, the terminal performs a packet size check; packets meeting the threshold criteria can trigger the SDT procedure. In practice, the size of the positioning information reported by the terminal exceeds the SDT packet threshold. To enable positioning information transmission via small packets, the sender can employ segmented measurement report reporting. However, in related technologies, since the LMF entity is unaware of the threshold configured by the base station for SDT packet transmission, the reported positioning measurement information and SDT packets are incompatible.

[0129] Based on this, the method provided in this embodiment of the invention involves a base station sending an indication message for a positioning measurement information service to a positioning server; the positioning server receiving the indication message for the positioning measurement information service from the base station; sending first information to a terminal; the first information including a first value and / or the indication message for the positioning measurement information service; the first value being used to limit the number of SDT data packets obtained by segmenting the positioning measurement information; and correspondingly, the terminal sending at least one data packet to the positioning server according to the first information.

[0130] The present invention will be further described in detail below with reference to the embodiments.

[0131] Figure 2 This is a flowchart illustrating a data interaction method provided in an embodiment of the present invention; as shown below. Figure 2As shown, the method is applied to a base station, such as an enhanced base station (eNB), a 5G base station (gNB), or an NB; the method includes:

[0132] Step 201: Send an instruction message for the positioning measurement information service to the positioning server.

[0133] In some embodiments, the indication message of the location measurement information service includes:

[0134] A first threshold; the first threshold is used to limit the size of the SDT data packet; the SDT data packet is related to positioning measurement information.

[0135] Here, the positioning measurement information includes: measurement reports, measurements, and location estimates, etc.

[0136] In practical applications, the base station can obtain a first threshold for limiting the amount of data sent by the terminal based on the amount of data from the terminal's positioning measurement information.

[0137] Based on this, in some embodiments, the first threshold is configured by the base station; the method further includes:

[0138] Receive a first data volume from the positioning server; the first data volume represents the amount of positioning measurement information data.

[0139] The first threshold is determined based on the first data volume.

[0140] The first data volume is determined based on at least one of the following methods:

[0141] Determined based on the magnitude of the positioning measurement information historically reported by the terminal;

[0142] The magnitude of the location measurement information sent by at least one terminal within the cell served by the base station is determined.

[0143] Specifically, the positioning server can determine the amount of positioning measurement information based on the historical data reported by the terminal. For example, the determination method could be to take the maximum value of the historical positioning measurement information data or to take the average value.

[0144] The data volume of the positioning measurement information can also be determined based on the magnitude of the positioning measurement information currently transmitted by at least one terminal within the cell served by the base station. For example, the determination method could be to take the maximum or average value of the data volume of the positioning measurement information currently transmitted by at least one terminal.

[0145] The step of determining the first threshold based on the first data volume includes:

[0146] According to preset rules, determine the first threshold corresponding to the first data volume;

[0147] The preset rule includes: at least one data quantity and a threshold corresponding to each data quantity; when applied, the preset rule is queried according to the first data quantity to determine the first threshold corresponding to the first data quantity.

[0148] In practical applications, after learning about the Quality of Service (QoS) request for location measurement information, the base station can determine the data packet transmission method and inform the terminal.

[0149] Based on this, in some embodiments, the method further includes:

[0150] Receive QoS requirements from the LCS (Location Server);

[0151] Determine the transmission method based on the QoS requirements of the LCS;

[0152] Send an instruction message indicating the sending method to the terminal;

[0153] The transmission method includes: transmitting positioning measurement information in a connected state or transmitting positioning measurement information in an inactive state.

[0154] For example, the QoS requirements may include: 'low delay', 'delay tolerant', and 'no delay'.

[0155] When the QoS requirement is 'low delay' or 'no delay', it indicates that the location is sensitive to latency, and the transmission method can be to send the location measurement information in an inactive state.

[0156] When the QoS requirement is 'delay tolerant', it indicates that there is a certain tolerance for positioning delay. The transmission method can be to send positioning measurement information in the connected state.

[0157] Here, the base station can pre-configure an uplink grant (UL grant), through which an indication message of the transmission method is sent to the terminal.

[0158] Figure 3 A flowchart illustrating another data interaction method provided in an embodiment of the present invention; as shown Figure 3 As shown, the method is applied to a positioning server; the positioning server is an entity implementing LMF, but in actual applications it can also be other devices implementing LMF. The name of the positioning server is not limited here. The method includes:

[0159] Step 301: Receive the instruction message of the positioning measurement information service from the base station;

[0160] Step 302: Send first information to the terminal; the first information includes a first value and / or an indication message of the positioning measurement information service; the first value is used to limit the number of SDT data packets obtained by segmenting the positioning measurement information.

[0161] In some embodiments, sending the first information to the terminal includes:

[0162] Send an LPP message to the terminal; the LPP message carries the first information.

[0163] In some embodiments, the indication information of the location measurement information service includes: a first threshold;

[0164] The first threshold is used to limit the size of the SDT data packet; the SDT data packet is related to positioning measurement information.

[0165] Here, the positioning measurement information includes: measurement reports, measurements, and location estimates, etc.

[0166] In some embodiments, corresponding to the case where the first information includes a first numerical value, the method further includes:

[0167] The first value is determined based on the first threshold and the second data quantity; wherein, the second data quantity represents the magnitude of the original positioning measurement information reported by the terminal.

[0168] Specifically, the first threshold is the maximum value of data sent by the terminal in the inactive state, and the first value is the minimum number of SDT data packets sent by the terminal.

[0169] Determining the first value based on the first threshold and the second data volume includes:

[0170] Divide the second data volume by the first threshold to obtain the first value.

[0171] Before determining the first value based on the first threshold and the second data volume, the method further includes:

[0172] Receive the second amount of data sent by the terminal.

[0173] Specifically, the positioning server can receive the size of the raw positioning measurement information reported by each terminal, i.e., receive the second data volume; for each terminal, the positioning server calculates and determines the first value corresponding to the terminal, i.e., it can limit the number of SDT data packets obtained by segmenting the positioning measurement information of the terminal.

[0174] The terminal may introduce a new information element (IE) in the request for auxiliary data message to inform the positioning server of the magnitude of its original positioning measurement information.

[0175] In some embodiments, the method further includes at least one of the following:

[0176] Send a first amount of data to the base station;

[0177] Send the LCS QoS requirements to the base station.

[0178] In some embodiments, the method further includes at least one of the following:

[0179] The receiving terminal sends N first data packets in the inactive state;

[0180] The receiving terminal sends M first data packets in the inactive state and a second data packet in the connected state;

[0181] Wherein, the first data packet and the second data packet include partial positioning measurement information; N is greater than or equal to a first value; the first data packet is an SDT data packet; the data volume of the first data packet is less than or equal to the first threshold; and M is less than N.

[0182] In this case, the data amounts of any two of the first data packets are the same or different.

[0183] Figure 4 This is a flowchart illustrating another data interaction method provided in an embodiment of the present invention; as follows: Figure 4 As shown, the method is applied to a terminal, which may be referred to as User Equipment (UE), Mobile Station (MS), or Mobile Terminal, etc.; the terminal may be a mobile phone, smartphone, laptop computer, digital radio receiver, personal digital assistant (PDA), tablet computer (PAD), portable multimedia player (PMP), wearable device (such as smart bracelet, smartwatch, etc.), navigation device, etc.; the method includes:

[0184] Step 401: Send a positioning measurement information data packet to the positioning server according to the first information; the first information includes a first value and / or an indication message of the positioning measurement information service; the first value is used to limit the number of SDT data packets obtained by segmenting the positioning measurement information.

[0185] In some embodiments, the method further includes:

[0186] Receive first information from the location server.

[0187] Here, receiving the first information from the positioning server may include: receiving an LPP message from the positioning server; the LPP message carrying the first information.

[0188] The positioning server can also introduce new IEs in the auxiliary data messages to indicate the minimum number of SDT data packets to be segmented or the maximum data size of the SDT data packets to be sent when the terminal reports positioning measurement information.

[0189] In some embodiments, the indication information of the location measurement information service includes: a first threshold;

[0190] The first threshold is used to limit the size of the SDT data packet; the SDT data packet is related to positioning measurement information.

[0191] Here, the positioning measurement information includes: measurement reports, measurements, and location estimates, etc.

[0192] Specifically, when the first information includes the first value, the terminal can select the number of SDT data packets to be segmented when sending positioning measurement information based on the first value (i.e., the minimum number of segments) provided by the positioning server (i.e., the entity of LMF). Each SDT data packet can be configured to have the same or different lengths, but it is necessary to ensure that the length of each SDT data packet is less than the first threshold (i.e., the threshold of the data packet).

[0193] When the first information includes the indication message of the positioning measurement information service, i.e. the first threshold, the terminal can also calculate the minimum number of SDT data packets that need to be segmented, and flexibly segment the reported positioning measurement information into a specific number of SDT data packets, and then report each SDT data packet to the base station, which then sends it to the positioning server. The size of each SDT data packet needs to be less than the first threshold.

[0194] In some embodiments, before receiving the first information from the location server, the method further includes:

[0195] A second data quantity is sent to the positioning server; the second data quantity represents the size of the original positioning measurement information reported by the terminal.

[0196] For example, the terminal can determine the second data volume based on the size of the location measurement information that needs to be reported. Alternatively, the terminal can determine the second data volume based on the average or maximum size of its historically reported location measurement information.

[0197] Here, the terminal may introduce a new IE in the request for auxiliary data message to inform the positioning server of the magnitude of the positioning measurement information.

[0198] In some embodiments, sending the location measurement information data packet to the location server includes at least one of the following:

[0199] The positioning measurement information is segmented based on the first information to obtain N first data packets; in the inactive state, the N first data packets are sent to the positioning server.

[0200] The positioning measurement information is segmented based on the first information to obtain a second data packet and M first data packets; the M first data packets are sent to the positioning server in the inactive state, and the second data packet is sent to the positioning server in the connected state;

[0201] Wherein, N is greater than or equal to the first value; the first data packet is an SDT data packet; the data volume of the first data packet is less than or equal to the first threshold; and M is less than N.

[0202] Here, the terminal configures the length of N data packets of positioning measurement information to be less than or equal to the first threshold according to the minimum number or the first threshold provided by the positioning server, and sends them to the terminal in the inactive state;

[0203] The terminal can also configure the length of the first M data packets of positioning measurement information to be less than or equal to the first threshold, and the length of the (M+1)th data packet to be greater than the first threshold. That is, the terminal can transmit the first M data packets through SDT, and the (M+1)th data packet enters the connection state for transmission.

[0204] In this case, the data amounts of any two of the first data packets are the same or different.

[0205] In practical applications, the terminal can send positioning measurement information to the positioning server using the above two methods. The specific sending method can be informed to the terminal in advance by the base station.

[0206] Based on this, in some embodiments, the method further includes:

[0207] Receive the instruction message indicating the sending method;

[0208] The transmission method includes: transmitting positioning measurement information in a connected state or transmitting positioning measurement information in an inactive state.

[0209] Corresponding to the case of sending positioning measurement information in the inactive state, the terminal can send N first data packets in the inactive state;

[0210] Corresponding to the case of sending positioning measurement information in the connected state, the terminal can send M first data packets in the inactive state and send second data packets in the connected state; or, it can directly send positioning measurement information in the connected state.

[0211] It should be noted that, Figure 4The method shown can be executed by the positioning module provided by the terminal or by the terminal's non-access stratum (NAS) layer.

[0212] The method provided in this invention enables the interaction of potential positioning assistance information (such as the indication message of the aforementioned positioning measurement information service and the QoS requirements of LCS) between the base station and the positioning server, achieves the adaptation of positioning measurement information and SDT data packets, and ensures that the terminal can report positioning measurement information via SDT in an inactive state. Simultaneously, it also proposes LMF setting LPP segmentation criteria, and information elements (IEs) exchanged in advance between the base station and the terminal to transmit the first value and / or the indication message of the positioning measurement information service.

[0213] This invention provides a method for location-assisted information interaction, such as... Figure 5 As shown, the method includes:

[0214] Step 501: The base station configures a first threshold and sends the first threshold to the positioning server; the first threshold is a threshold that limits the maximum value of SDT data packets;

[0215] Here, in order to optimize the size of the SDT data packets for positioning measurement information, the positioning server obtains the configured threshold for the SDT data packets, i.e., the first threshold, by interacting with the base station. The positioning server is an LMF entity.

[0216] Specifically, the base station estimates the amount of data (equivalent to the first data amount mentioned above) based on the positioning measurement information, configures a first threshold, and sends the configured first threshold to the positioning server.

[0217] The positioning server can adjust the size of the positioning measurement information according to the first threshold to adapt to the target audience.

[0218] Step 502: The positioning server sends a first threshold to the terminal, or determines a first value based on the first threshold and sends it to the terminal;

[0219] Step 503: The terminal determines the first value and sends a positioning measurement information data packet to the positioning server.

[0220] Here, the first value is the minimum number of SDT data packets that need to be segmented when segmenting positioning measurement information.

[0221] Specifically, in order to obtain the size of the positioning measurement information, the terminal can introduce a new IE (Indicator of Information) in the Request for Assisted Data message to indicate the amount of positioning measurement information. After the positioning server knows the size of the positioning measurement information, it introduces a new IE in the Provide Assisted Data message to indicate the minimum number of SDT (Segmented Data Packet) packets that the terminal needs to segment when reporting the positioning measurement information (i.e., the first value).

[0222] Here, we provide an application embodiment. In a practical application scenario, the base station (gNB) sends a configured first threshold (i.e., a threshold limiting the maximum value of SDT data packets) to the positioning server (such as an LMF entity). After receiving the first threshold, the positioning server calculates the minimum number of SDT data packets (i.e., a first value) to be obtained by segmenting the positioning measurement information based on the size of the original positioning measurement information reported by the terminal or the size of the previously stored positioning measurement information, and sends the first value to the terminal. The terminal's NAS layer can select the number of SDT data packets to be segmented according to the first value. Each SDT data packet can be configured to have the same or different lengths, but it is necessary to ensure that the length of each SDT data packet is less than the first threshold. Each SDT data packet obtained from the segmentation of positioning measurement information is uploaded via SDT. Alternatively, the terminal's NAS layer can also configure the length of the first M SDT data packets of the positioning measurement information to be less than the first threshold, and the length of the (M+1)th data packet to be greater than the first threshold. The terminal can transmit the first M data packets via SDT, and the (M+1)th data packet enters the connection state for transmission.

[0223] Another application embodiment is provided. In a practical application scenario, the base station (gNB) sends a configured first threshold (i.e., the threshold limiting the maximum value of SDT data packets) to the positioning server (such as an LMF entity). The positioning server can then send the first threshold to the terminal, which can be configured through its own NAS layer. Afterward, the terminal calculates the minimum number of SDT data packets (i.e., the first value) obtained by segmenting the positioning measurement information, and flexibly configures the reported positioning measurement information to a specific number (greater than or equal to the first value) to be reported to the positioning server. The length of each SDT data packet must be less than the SDT data packet threshold; that is, the terminal can calculate the first value based on the first threshold. Alternatively, the terminal's NAS layer can also configure the length of the first M SDT data packets of the positioning measurement information to be less than the first threshold, and the length of the (M+1)th data packet to be greater than the first threshold. The terminal can transmit the first M SDT data packets via SDT, and the (M+1)th data packet enters the connected state for transmission.

[0224] In order to achieve the first threshold for base station configuration, before step 501, the step may further include: the base station determining the estimated data volume of positioning measurement information (equivalent to the first data volume mentioned above).

[0225] In one example, the location server can interact with the base station to estimate the amount of location measurement information (SDT) data. Without obtaining the size of the SDT data, the location server can segment the data and store the sizes of historically reported SDT data from the terminal. Based on these historically reported sizes, the estimated SDT data size is determined. The location server then sends the appropriate estimated SDT data size to the base station via the NR Location Protocol A (NRPPa) procedure, enabling the base station to configure the threshold for SDT packets.

[0226] In another example, the positioning server can interact with the terminal to estimate the amount of positioning measurement information (STM). Specifically, the positioning server sends the estimated STM to the terminal via an LPP message. When the terminal sends an auxiliary message request to the base station, it includes the estimated STM in the request so that the base station can adjust the appropriate threshold for reporting SDT data packets.

[0227] The method further includes:

[0228] Step 504: The positioning server interacts with the base station to determine the QoS requirements of the Location Service (LCS); after the base station determines the QoS request, it pre-configures an appropriate segmentation strategy and grants it to the terminal via uplink grant (UL grant).

[0229] Here, the QoS requirements of the LCS represent the request for location and can be determined by the location server.

[0230] The QoS requirements of the LCS can be divided according to the acceptable latency of the determined terminal location; for example, the possible QoS requirements of the service are 'low delay', 'delay tolerant', and 'no delay'.

[0231] If the QoS requirement of the location measurement information data packet is 'low delay' or 'no delay', it indicates that the location is sensitive to latency, and the data packet is less than or equal to the first threshold. Therefore, the size of the data packet is considered to meet the SDT requirements. Such location measurement information data packets need to be uploaded directly in the inactive state via SDT.

[0232] If the QoS requirement of the location measurement information data packet is 'delay tolerant', indicating a certain tolerance for location delay, and / or the data packet is larger than the first threshold, then the size of the data packet is considered not to meet the SDT requirements. Such location measurement information data packets can be switched to the active state and uploaded via LPP or uploaded in the inactive state in a segmented form.
