[0002] The 5G system architecture is defined as a service-based architecture, meaning it implements system functions by providing services to other authorized NFs through a set of Network Functions (NFs) in order to access those services. An NF service is a function that an NF (as an NF service producer) exposes to other authorized NFs (as NF service consumers) through a service-based interface. An NF service can support one or more NF service operations. An NF can provide different NF services.

[0003] After the introduction of service-oriented functions into the Radio Access Network (RAN) architecture, there has been no optimization design based on service-oriented interfaces for uplink and downlink positioning processing mechanisms, especially in the area of ​​distributed function transmission information.

The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0196] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0197] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0198] To facilitate understanding of the solution proposed in this application, the relevant content will be introduced first.

[0199] I. 5G Network Architecture and Interface Definition

[0200] A Next Generation Radio Access Network (NG-RAN) comprises one or more base stations (gNBs). A gNB can consist of a gNB Centralized Unit (gNB-CU) and one or more gNB Distributed Units (gNB-DUs). The gNB-CU hosts the gNB's Radio Resource Control (RRC), Service Data Adaptation Protocol (SDAP), and Packet Data Convergence Protocol (PDCP). It supports functions such as UE radio access control, UE connection control, radio bearer control, mobility management, and paging. The gNB-DU carries the gNB's Radio Link Control (RLC), Media Access Control (MAC), and physical layer; some of its operations are controlled by the gNB-CU.

[0201] The 5G core network (5GC) includes Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF). AMF includes one or more of the following functions: connection management, registration management, reachability management, mobility management, non-access stratum (NAS) messaging, access authentication, and access authorization. SMF includes one or more of the following functions: session management, terminal IP address allocation and management, and selection and control of user plane functions. UPF includes one or more of the following functions: packet routing and forwarding, and user plane QoS processing. AMF and SMF can provide services through their respective service-based interfaces, and AMF and SMF interact with each other through the same service-based interface.

[0202] like Figure 1 The diagram shows the overall architecture of NG-RAN. The gNB and 5GC are connected via the NG interface. For the user plane, the gNB-CU and UPF transmit UE user plane data via the NG-U interface. For the control plane, the gNB-CU and AMF transmit signaling via the NG-C interface. Information exchanged between the gNB-CU and SMF is transparently forwarded through the NG-C interface and the AMF's service-based interface.

[0203] II. Processing of 5G Location Messages

[0204] In the 5G CU-DU separation architecture, only the gNB-CU can communicate directly with the Local Management Function (LMF), and the AMF is the forwarding node for signaling between the base station and the LMF. The signaling flow is as follows:

[0205] Location signaling: gNB-CU<->AMF<->LMF

[0206] After performing uplink positioning measurements, the gNB-DU transmits the measurement results to the gNB-CU via the F1 Application Protocol (F1AP). The gNB-CU then transmits the results to the AMF via the Next Generation Application Protocol (NGAP), and the AMF forwards them to the LMF.

[0207] III. Service-based architecture

[0208] The 5G system architecture includes a set of network functions. A Network Function (NF) is a processing function within the system that defines its functional behavior and interfaces. An NF can be implemented as a network element on dedicated hardware, as a software instance running on dedicated hardware, or as a virtualized function instantiated on a platform, such as on cloud infrastructure. The 5G system architecture is defined as a service-based architecture, meaning it implements system functions by providing services to other authorized NFs through a set of NFs in order to access those services. An NF service is a function exposed by an NF (as an NF service producer) to other authorized NFs (as NF service consumers) through a service-based interface. An NF service can support one or more NF service operations. An NF can provide different NF services.

[0209] Interactions between network functions can be represented in two ways: service-based representation and reference point representation. In service-based representation, a network function allows other authorized network functions to access its services. Reference point representation illustrates the interaction between two network functions, described by a point-to-point reference point between them.

[0210] IV. Description of some typical service-oriented functions

[0211] Radio Network Function (RNF): This mainly includes radio resource management, establishment / deletion of radio connections, session management, measurement and control, and scheduling and transmission of certain system messages.

[0212] Radio Distributed Unit Function (RDUF): mainly includes the processing functions of the RLC, MAC and physical PHY layers of the radio bearer, or the non-high-layer processing functions of the radio bearer, which also undertakes the scheduling and transmission of some system messages.

[0213] After introducing service-oriented functions into the RAN architecture, there has been no optimization design based on service-oriented interfaces for the uplink and downlink positioning processing mechanisms, especially in the area of ​​distributed function transmission information. This results in the inability to significantly reduce the transmission latency of positioning information, thereby affecting the positioning performance of the entire network.

[0214] To address the aforementioned technical problems, embodiments of this application provide information transmission methods, apparatuses, devices, and media. The methods and apparatuses are based on the same concept. Since the methods and apparatuses solve problems in similar ways, their implementations can be mutually referenced, and repeated details will not be elaborated upon.

[0215] like Figure 2The diagram shown is a flowchart illustrating an information transmission method provided in an embodiment of this application. This method is applied to a first wireless distributed unit function, meaning it is executed by the first wireless distributed unit function. Specifically, the method of this application may include:

[0216] Step 201: Receive a target service request related to location.

[0217] Specifically, the first wireless distributed unit function directly receives location-related target service requests. It should be understood that "directly receiving" means that the first wireless distributed unit function directly receives location-related target service requests sent by the service initiator (hereinafter, this could be the location service function or the second wireless distributed unit function), without requiring forwarding from other devices.

[0218] The wireless distributed unit function can realize the first network sub-function related to positioning. This first network sub-function can also be called wireless network function, wireless distributed user function, wireless centralized user function, etc.

[0219] Optionally, the target service request may include one of the following: an uplink positioning measurement request, a downlink positioning measurement request, or a positioning configuration request.

[0220] Step 202: Perform the operation related to the target service request to obtain the requested service result.

[0221] Step 203: Send the service result of the request to the location service function.

[0222] In this process, the first wireless distributed unit function directly sends the service result of the request to the location service function, without the need for forwarding by other devices.

[0223] The location service function can implement a second network sub-function related to location, which can also be called location service function, wireless network function, wireless centralized user function, etc. Among them, the location service function can be LMF.

[0224] The information transmission method in this application embodiment directly receives a target service request related to positioning; performs an operation related to the target service request to obtain the requested service result; and finally directly sends the requested service result to the positioning service function. In this way, after RAN service-oriented architecture, by allowing direct interaction of location-related information between the radio distributed unit function and the designated positioning service function, the uplink and downlink positioning processing mechanism is supported, thereby reducing the transmission latency of positioning information and further improving the positioning performance of the entire network.

[0225] In some embodiments, step 201 above, receiving a location-related target service request, may include:

[0226] Receive location-related target service requests through the first protocol;

[0227] Accordingly, step 203 above, sending the service result of the request to the location service function, includes:

[0228] The service result of the request is sent to the location service function through the first protocol;

[0229] The first protocol includes one of the following:

[0230] Hypertext Transfer Protocol (HTTP) 2 / Transport Layer Security (TLS);

[0231] Transmission Control Protocol (TCP) / Internet Protocol (IP);

[0232] Hypertext Transfer Protocol HTTP / 3;

[0233] Quick User Datagram Protocol Internet Connections (QUIC);

[0234] IP.

[0235] Through the aforementioned first protocol, direct interaction of location-related information between the wireless distributed unit function and the designated location service function can be achieved.

[0236] Optionally, the target service request may include at least one of the following:

[0237] Uplink positioning measurement request;

[0238] Downlink positioning measurement request;

[0239] Locate the configuration request.

[0240] In some embodiments, step 201 above, receiving a target service request related to location, includes:

[0241] Receive an uplink positioning measurement request sent by the positioning service function, wherein the service result of the request further includes configuration information of the uplink positioning resources; or,

[0242] Receives uplink positioning measurement requests sent by the second wireless distributed unit function.

[0243] Here, the first wireless distributed unit function receives the uplink positioning measurement request sent by the second wireless distributed unit function, indicating that the first wireless distributed unit function is a participant in the uplink positioning measurement. This is applicable to scenarios where multiple wireless distributed unit functions need to participate in the uplink positioning measurement. In this scenario, the second wireless distributed unit function receives the uplink positioning measurement request sent by the positioning service function, and after configuring uplink positioning resources, sends the uplink positioning measurement request to the first wireless distributed unit function, with the aim of enabling the first wireless distributed unit function to participate in the uplink positioning measurement.

[0244] Accordingly, step 202 above, which involves performing operations related to the target service request and obtaining the requested service result, may include:

[0245] Based on the uplink positioning measurement request, obtain the configuration information of the uplink positioning resources;

[0246] If the uplink positioning measurement request is sent by the positioning service function and received by the first wireless distributed unit function, the uplink positioning measurement request may include the identification information of the terminal to be located, the relevant information of the requested uplink positioning resources, the uplink positioning measurement reporting method, and the identification information of the second wireless distributed unit function (optional). The first wireless distributed unit function allocates uplink positioning resources according to the uplink positioning measurement request and obtains the configuration information of the uplink positioning resources.

[0247] If the uplink positioning measurement request is received by the first radio distributed unit function from the second radio distributed unit function, then the uplink positioning measurement request may include the identification information of the terminal to be located, the uplink positioning measurement reporting method, the configuration information of the uplink positioning resources, and the identification information of the positioning service function. The first radio distributed unit function obtains the configuration information of the uplink positioning resources based on the content contained in the uplink positioning measurement request. Furthermore, it can also obtain the identification information of the terminal to be located and the positioning service function to determine which positioning service function to send the uplink positioning measurement results to.

[0248] Based on the configuration information of the uplink positioning resources, an uplink positioning measurement is performed to obtain the uplink positioning measurement result, and the requested service result includes the uplink positioning measurement result.

[0249] It should be noted that the terminal side also obtains the configuration information of the uplink positioning resources. Therefore, based on the configuration information of the uplink positioning resources, uplink positioning measurements are performed, which may specifically include:

[0250] On the uplink positioning resources corresponding to the configuration information of the uplink positioning resources, the uplink positioning reference signal sent by the terminal is received; based on the uplink positioning reference signal, uplink positioning measurement is performed to obtain the uplink positioning measurement result.

[0251] The terminal sends uplink positioning reference signals on the uplink positioning resources corresponding to the configuration information of the uplink positioning resources.

[0252] Here, the terminal can obtain the configuration information of the uplink positioning resources in the following two ways.

[0253] Method 1

[0254] The first wireless distributed unit function allocates uplink positioning resources according to the uplink positioning measurement request. After obtaining the configuration information of the uplink positioning resources, it sends a resource configuration message to the terminal. The resource configuration message includes the configuration information of the uplink positioning resources.

[0255] Method 2

[0256] The first wireless distributed unit function allocates uplink positioning resources according to the uplink positioning measurement request. After obtaining the configuration information of the uplink positioning resources, it sends a resource configuration request to the Radio Network Function (RNF) unit. The resource configuration request includes the configuration information of the uplink positioning resources. The RNF unit then sends a resource configuration message to the terminal. The resource configuration message includes the configuration information of the uplink positioning resources.

[0257] That is, through the forwarding of the RNF unit, the terminal obtains the configuration information of the uplink positioning resources.

[0258] Optionally, the uplink positioning measurement request may include one or more of the following:

[0259] Identification information of the terminal that needs to be located;

[0260] Request information related to uplink location resources;

[0261] The reporting method for uplink positioning measurements;

[0262] Identification information for the second wireless distributed unit function;

[0263] Configuration information of uplink positioning resources;

[0264] Identification information for location service functions.

[0265] The following two examples illustrate this; see below. Figure 3 Example 1 and Figure 4In Embodiment 2, from the perspective of the interaction between the wireless distributed unit function and the positioning service function, the specific implementation process of the information transmission method of this application is described when the target service request includes an uplink positioning measurement request.

[0266] It should be noted that, in this embodiment, the wireless distributed unit function is RDUF and the location service function is LMF.

[0267] Example 1

[0268] Step 31: LMF sends an uplink positioning measurement request to RDUF1.

[0269] Specifically, the LMF decides to initiate uplink positioning measurement by sending an uplink positioning measurement request to RDUF1 directly based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. The uplink positioning measurement request includes at least: the identifier of the UE to be located, relevant information on the requested uplink positioning resources, and the reporting method for the uplink positioning measurement.

[0270] Step 32: RDUF1 allocates uplink positioning resources and obtains the configuration information of the uplink positioning resources.

[0271] Step 33: RDUF1 sends a resource configuration message to the UE, which includes configuration information for uplink positioning resources.

[0272] Specifically, RDUF1 sends the allocated uplink positioning resources to the corresponding UE through the air interface between RDUF and UE. The specific protocol stack can be RRC, MAC, or other new protocols.

[0273] (Optional) Step 33a: RDUF1 sends a resource configuration request to RNF, which includes configuration information for uplink positioning resources.

[0274] Here, RDUF1 forwards the configuration information containing uplink positioning resources to RNF.

[0275] (Optional) Step 33b: The RNF sends a resource configuration message to the UE, which includes configuration information for uplink positioning resources.

[0276] Here, the RNF sends the allocated uplink positioning resources to the corresponding UE through its air interface with the UE. The specific protocol stack can be RRC or other new protocols.

[0277] (Optional) Step 33c: RNF returns a resource configuration response to RDUF1.

[0278] It should be noted that steps 33a to 33c are another way for the terminal to obtain the configuration information of uplink positioning resources.

[0279] Step 34: RDUF1 sends an uplink positioning measurement response to LMF, which includes configuration information of uplink positioning resources.

[0280] Specifically, RDUF1 directly sends an uplink positioning measurement response to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP, where the uplink positioning measurement response includes configuration information of the uplink positioning resources.

[0281] Step 35: RDUF1 sends uplink positioning measurement result 1 to LMF.

[0282] Here, RDUF1 receives the uplink positioning reference signal sent by the UE based on the uplink positioning resource configuration information corresponding to the uplink positioning resource, performs uplink positioning measurement according to the uplink positioning reference signal, and obtains uplink positioning measurement result 1. Specifically, RDUF1 directly sends uplink positioning measurement result 1 to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP.

[0283] When multiple RDUFs are required to participate in uplink positioning measurements, the following steps can be performed.

[0284] (Optional) In step 36a, the LMF sends an uplink positioning measurement request to the RDUF2.

[0285] Specifically, LMF directly sends an uplink positioning measurement request to RDUF2 based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. The uplink positioning measurement request includes at least: the identifier of the UE to be located, the configuration information of the uplink positioning resources, and the reporting method of the uplink positioning measurement.

[0286] (Optional) In step 36b, RDUF2 sends an uplink positioning measurement response to LMF.

[0287] (Optional) Step 37, RDUF2 sends uplink positioning measurement result 2 to LMF.

[0288] Here, RDUF2 receives the uplink positioning reference signal sent by the UE based on the uplink positioning resource configuration information corresponding to the uplink positioning resource, and performs uplink positioning measurement according to the uplink positioning reference signal to obtain uplink positioning measurement result 2. Specifically, RDUF2 directly sends uplink positioning measurement result 2 to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. Finally, LMF calculates the UE's location based on the received uplink positioning measurement result.

[0289] Example 2

[0290] Step 41: LMF sends an uplink positioning measurement request to RDUF1.

[0291] Specifically, the LMF decides to initiate uplink positioning measurements by directly sending an uplink positioning measurement request to RDUF1 based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. The uplink positioning measurement request includes at least: the identifier of the UE to be located, relevant information about the requested uplink positioning resources, and the reporting method for the uplink positioning measurement. In addition, it also includes information about other positioning service providers participating in the uplink positioning measurement, such as the Radio Distributed Unit Function identifier information.

[0292] Step 42: RDUF1 allocates uplink positioning resources and obtains the configuration information of the uplink positioning resources.

[0293] Step 43: RDUF1 sends a resource configuration message to the UE, which includes configuration information for uplink positioning resources.

[0294] Specifically, RDUF1 sends the allocated uplink positioning resources to the corresponding UE through the air interface between RDUF and UE. The specific protocol stack can be RRC, MAC, or other new protocols.

[0295] (Optional) Step 43a: RDUF1 sends a resource configuration request to RNF, which includes configuration information for uplink positioning resources.

[0296] Here, RDUF1 forwards the configuration information containing uplink positioning resources to RNF.

[0297] (Optional) Step 43b: The RNF sends a resource configuration message to the UE, which includes configuration information for uplink positioning resources.

[0298] Here, the RNF sends the allocated uplink positioning resources to the corresponding UE through its air interface with the UE. The specific protocol stack can be RRC or other new protocols.

[0299] (Optional) Step 43c: RNF returns a resource configuration response to RDUF1.

[0300] It should be noted that steps 43a to 43c are another way for the terminal to obtain the configuration information of uplink positioning resources.

[0301] Step 44: RDUF1 sends an uplink positioning measurement response to LMF, which includes configuration information of uplink positioning resources.

[0302] Specifically, RDUF1 directly sends an uplink positioning measurement response to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP, where the uplink positioning measurement response includes configuration information of the uplink positioning resources.

[0303] Step 45, RDUF1 sends uplink positioning measurement result 1 to LMF.

[0304] When multiple RDUFs are required to participate in uplink positioning measurements, the following steps can be performed.

[0305] (Optional) In step 46a, RDUF1 sends an uplink positioning measurement request to RDUF2.

[0306] Specifically, RDUF1 directly sends an uplink positioning measurement request to RDUF2 (i.e., other location service producers) based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This uplink positioning measurement request includes establishing uplink positioning measurement information, such as uplink positioning resource configuration information, uplink positioning measurement reporting methods, and LMF identification information (i.e., location service consumer information).

[0307] (Optional) In step 46b, RDUF2 returns an uplink positioning measurement response to RDUF1.

[0308] (Optional) Step 47, RDUF2 sends uplink positioning measurement result 2 to LMF.

[0309] Here, RDUF2 receives the uplink positioning reference signal sent by the UE based on the uplink positioning resource configuration information corresponding to the uplink positioning resource, and performs uplink positioning measurement according to the uplink positioning reference signal to obtain uplink positioning measurement result 2. Specifically, RDUF2 directly sends uplink positioning measurement result 2 to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. Finally, LMF calculates the UE's location based on the received uplink positioning measurement result.

[0310] In some embodiments, step 202 above, which involves performing operations related to the target service request to obtain the requested service result, includes:

[0311] Based on the downlink positioning measurement request, the configuration information of the downlink positioning resources is obtained, and the service result of the request includes the configuration information of the downlink positioning resources.

[0312] Specifically, the first wireless distributed unit function allocates downlink positioning resources and obtains the configuration information of downlink positioning resources based on the downlink positioning measurement request.

[0313] Optionally, the downlink positioning measurement request includes one or more of the following information:

[0314] Identification information of the terminal that needs to be located;

[0315] Request information related to downlink location resources;

[0316] Reporting method for downlink positioning measurements.

[0317] It should be noted that the downlink positioning measurement is performed by the terminal side. The terminal can receive configuration information of downlink positioning measurement resources sent by the positioning service function. Then, on the downlink positioning resources corresponding to the configuration information, the terminal receives a downlink positioning reference signal sent by the first wireless distributed unit function; based on the downlink positioning reference signal, it performs downlink positioning measurement to obtain the downlink positioning measurement result. Afterwards, the downlink positioning measurement result is sent to the positioning service function.

[0318] The following embodiments illustrate how to enable the location service function to obtain the configuration information of downlink location measurement resources.

[0319] In an optional embodiment, the method of this application further includes:

[0320] Send a downlink positioning measurement response to the positioning service function, the downlink positioning measurement response including configuration information of downlink positioning measurement resources.

[0321] The following is an example, see Figure 5 In Embodiment 3, from the perspective of the interaction between the wireless distributed unit function and the positioning service function, the specific implementation process of the information transmission method of this application is described when the target service request includes a downlink positioning measurement request.

[0322] It should be noted that, in this embodiment, the wireless distributed unit function is RDUF and the location service function is LMF.

[0323] Example 3

[0324] Step 51: LMF sends a downlink positioning measurement request to RDUF1.

[0325] Specifically, the LMF decides to initiate downlink location measurement by sending a downlink location measurement request to RDUF1 directly based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. The downlink location measurement request includes at least: the identifier of the UE to be located, and relevant information about the requested downlink location resources.

[0326] Step 52: RDUF1 allocates downlink positioning resources and obtains the configuration information of the downlink positioning resources.

[0327] Step 53: RDUF1 returns the downlink positioning measurement response to LMF.

[0328] Specifically, RDUF1 directly returns a downlink positioning measurement response to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This downlink positioning measurement response includes configuration information for downlink positioning resources.

[0329] When multiple RDUFs are required to participate in downlink positioning measurements, the following steps can be performed.

[0330] (Optional) In step 53a, the LMF sends a downlink positioning measurement request to the RDUF2.

[0331] Specifically, LMF directly sends a downlink positioning measurement request to RDUF2 based on one of the following: HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. The downlink positioning measurement request includes at least: the identifier of the UE to be located, and relevant information about the requested downlink positioning resources.

[0332] (Optional) Step 53b: RDUF2 allocates downlink positioning resources and obtains the configuration information of the downlink positioning resources.

[0333] (Optional) In step 53c, RDUF2 returns a downlink positioning measurement response to LMF, which includes configuration information of the downlink positioning resources.

[0334] Step 54: The LMF sends a location request message to the UE. The location request message includes at least the configuration information of downlink positioning resources and the reporting method of downlink positioning measurements. The configuration information of downlink positioning resources can be allocated from RDUF1, or it can be allocated from both RDUF1 and RDUF2.

[0335] Specifically, the LMF sends a location request message to the UE through the location protocol between the LMF and the UE.

[0336] (Optional) In step 55, the UE sends a location response message to the LMF.

[0337] Specifically, the UE sends a location response message to the LMF through the location protocol between the UE and the LMF.

[0338] Step 56: The UE sends the downlink positioning measurement results to the LMF.

[0339] The UE performs downlink positioning measurements and sends the downlink positioning measurement results to the LMF via the positioning protocol between the UE and the LMF.

[0340] Specifically, when multiple RDUFs are not required to participate in downlink positioning measurement, the UE receives the downlink positioning reference signal sent by RDUF1, performs positioning measurement based on the downlink positioning reference signal, obtains the downlink positioning measurement result, and sends the downlink positioning measurement result to LMF.

[0341] When multiple RDUFs are required to participate in downlink positioning measurements, the UE receives a downlink positioning reference signal from RDUF1 and performs positioning measurements based on this signal to obtain downlink positioning measurement result 1. The UE also receives a downlink positioning reference signal from RDUF2 and performs positioning measurements based on this signal to obtain downlink positioning measurement result 2. Downlink positioning measurement result 1 and downlink positioning measurement result 2 are then sent to the LMF. Finally, the LMF calculates the UE's location based on the received downlink positioning measurement results.

[0342] In some embodiments, step 402 above, which involves performing operations related to the target service request to obtain the requested service result, includes:

[0343] Based on the location configuration request, the target location resource is deactivated and the deactivation result is obtained. The service result of the request includes the deactivation result, wherein the target location resource is at least a portion of the uplink location resource or at least a portion of the downlink location resource.

[0344] The following is an example, see Figure 6 Example 4 and Figure 7 Example 5 describes the specific implementation process of the information transmission method of this application from the perspective of the interaction between the wireless distributed unit function and the location service function, when the target service request includes a location configuration request.

[0345] Example 4

[0346] Step 61: LMF sends a downlink positioning configuration request to RDUF1.

[0347] Specifically, when LMF decides to deactivate some or all downlink location resources, it sends a downlink location configuration request to RDUF1 directly based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This downlink location configuration request includes at least information about the downlink location resources to be deactivated.

[0348] Step 62: RDUF1 deactivates the corresponding downlink positioning resources.

[0349] Step 63: RDUF1 sends a downlink positioning configuration response to LMF.

[0350] Specifically, RDUF1 directly sends a downlink location configuration response to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This downlink location configuration response contains deactivation result information, such as whether the deactivation was fully successful or partially successful.

[0351] Example 5

[0352] Step 71: LMF sends an uplink positioning configuration request to RDUF1.

[0353] Specifically, when LMF decides to deactivate some or all uplink location resources, it sends an uplink location configuration request to RDUF1 directly based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This uplink location configuration request includes at least information about the uplink location resources to be deactivated.

[0354] Step 72: RDUF1 deactivates the corresponding uplink positioning resources.

[0355] Step 73: RDUF1 sends a resource configuration message to the UE.

[0356] Specifically, RDUF1 sends resource configuration messages to the corresponding UE through the air interface between RDUF and UE. The specific protocol stack can be RRC, MAC, or other new protocols. The resource configuration message includes information on the uplink positioning resources that need to be deactivated.

[0357] (Optional) In step 73a, RDUF1 sends a resource configuration request to RNF, which includes information on uplink positioning resources that need to be deactivated.

[0358] (Optional) In step 73b, the RNF sends a resource configuration message to the UE.

[0359] Specifically, the RNF sends resource configuration messages to the corresponding UE through its air interface with the UE. The specific protocol stack can be RRC, MAC, or other new protocols. The resource configuration message includes information on the uplink positioning resources that need to be deactivated.

[0360] (Optional) In step 73c, RNF returns a resource configuration response to RDUF1.

[0361] Step 74: RDUF1 sends a downlink positioning configuration response to LMF.

[0362] Specifically, RDUF1 directly sends a downlink location configuration response to LMF based on one of HTTP2 / TLS, TCP / IP, HTTP3, QUIC, or IP. This downlink location configuration response contains deactivation result information, such as whether the deactivation was fully successful or partially successful.

[0363] The information transmission method in this application embodiment directly receives a target service request related to positioning; performs an operation related to the target service request to obtain the requested service result; and finally directly sends the requested service result to the positioning service function. In this way, after RAN service-oriented architecture, by allowing direct interaction of location-related information between the radio distributed unit function and the designated positioning service function, the uplink and downlink positioning processing mechanism is supported, thereby reducing the transmission latency of positioning information and further improving the positioning performance of the entire network.

[0364] like Figure 8 The diagram shown is a flowchart illustrating an information transmission method provided in an embodiment of this application. This method is applied to a location service function, meaning it is executed by a location service function (such as LMF). Specifically, the method of this application may include:

[0365] Step 801: Send a location-related target service request to the first wireless distributed unit function.

[0366] Specifically, the location service function directly sends location-related target service requests to the first wireless distributed unit function. Here, "directly sending" means that the location service function does not need to rely on other devices to forward location-related target service requests to the first wireless distributed unit function.

[0367] It should be noted that this embodiment is a method embodiment corresponding to the first wireless distributed unit function described above, namely the location service function side. For a detailed understanding and explanation of the relevant terms or steps, please refer to the description of the method section on the first wireless distributed unit function side; it will not be repeated here.

[0368] Step 802: Receive the service result of the request sent by the first wireless distributed unit function.

[0369] The location service function directly receives the service result of the request sent by the first wireless distributed unit function, without the need for forwarding by other devices.

[0370] The information transmission method of this application embodiment directly sends a target service request related to positioning to the first radio distributed unit function and directly receives the service result of the request sent by the first radio distributed unit function. In this way, after RAN service-orientation, by allowing direct interaction of location-related information between the radio distributed unit function and the designated positioning service function, the uplink and downlink positioning processing mechanism is supported, thereby reducing the transmission latency of positioning information and further improving the positioning performance of the entire network.

[0371] In some embodiments, step 801 above, sending a location-related target service request to the first wireless distributed unit function, may include:

[0372] The first protocol is used to send a location-related target service request to the first wireless distributed unit function.

[0373] Accordingly, step 802 above, receiving the service result of the request sent by the first wireless distributed unit function, may include:

[0378] HTTP3;

[0379] QUIC;

[0380] IP.

[0381] Through the aforementioned first protocol, direct interaction of location-related information between the wireless distributed unit function and the designated location service function can be achieved.

[0382] Optionally, the target service request may include at least one of the following:

[0383] Uplink positioning measurement request;

[0384] Downlink positioning measurement request;

[0385] Locate the configuration request.

[0386] In some embodiments, the target service request includes an uplink positioning measurement request, and the service result of the request includes a first uplink positioning measurement result and configuration information of uplink positioning resources; the uplink positioning measurement request includes one or more of the following:

[0391] Here, the service result of the request includes the configuration information of the uplink positioning resources obtained by the first wireless distributed unit function based on the uplink positioning measurement request; and the uplink positioning measurement result (i.e., the first uplink positioning measurement result) obtained by the first wireless distributed unit function performing uplink positioning measurement according to the configuration information of the uplink positioning resources.

[0392] Based on the above embodiments, as an optional embodiment, the method of this application further includes:

[0393] The system receives a second uplink positioning measurement result sent by the second wireless distributed unit function, and the requested service result also includes the second uplink positioning measurement result.

[0394] This embodiment corresponds to a scenario where multiple wireless distributed unit functions need to participate in uplink positioning measurements. The positioning service function not only receives the first uplink positioning measurement result sent by the first wireless distributed unit function, but also receives the second uplink positioning measurement result sent by the second wireless distributed unit function (which should be understood as other wireless distributed unit functions besides the first wireless distributed unit function).

[0395] Before receiving the second uplink positioning measurement result transmitted by the second wireless distributed unit function, the method of this application further includes:

[0396] Send an uplink positioning measurement request to the second wireless distributed unit function;

[0399] The reporting method for uplink positioning measurements;

[0400] Configuration information of uplink positioning resources;

[0401] Identification information for location service functions.

[0402] Here, after receiving the uplink positioning measurement request sent by the positioning service function, the second wireless distributed unit function obtains the configuration information of the uplink positioning resources. Then, based on this configuration information, it performs uplink positioning measurement to obtain a second uplink positioning measurement result. Finally, it directly sends the second uplink positioning measurement result to the positioning service function. That is, it executes the step of receiving the second uplink positioning measurement result sent by the second wireless distributed unit function.

[0403] In an embodiment where the service result based on the above request includes a first uplink positioning measurement result, or in an embodiment where the service result based on the above request includes both a first uplink positioning measurement result and a second uplink positioning measurement result, as an optional embodiment, the method of this application further includes:

[0404] Based on the service result of the request, the location information of the terminal is determined.

[0405] Specifically, the terminal's location information is calculated based on the first uplink positioning measurement result. This corresponds to a scenario where only one wireless distributed unit function is needed to participate in the uplink positioning measurement.

[0406] Alternatively, the terminal's location information can be calculated based on the first and second uplink positioning measurement results. This corresponds to a scenario where multiple Radio Distributed Unit (RDU) functions are required to participate in the uplink positioning measurement. For a clearer understanding of the uplink positioning measurement between the RDU function and the positioning service function, please refer to Embodiments 1 and 2 above.

[0407] In some embodiments, the target service request includes a downlink positioning measurement request; the service result of the request includes configuration information of downlink positioning resources;

[0412] Here, the service result of the request includes the configuration information of downlink positioning resources obtained by the first wireless distributed unit function based on the downlink positioning measurement request.

[0413] In some embodiments, the method of this application further includes:

[0414] Send a downlink positioning measurement request to the second wireless distributed unit function;

[0415] Here, after receiving a downlink positioning measurement request, the second wireless distributed unit function allocates downlink positioning resources and obtains the configuration information of the downlink positioning resources.

[0418] Identification information of the terminal that needs to be located;

[0419] Request information related to downlink location resources;

[0420] Reporting method for downlink positioning measurements.

[0421] It should be noted that when the target service request includes a downlink positioning measurement request, the downlink positioning measurement is performed by the terminal. Therefore, based on the embodiment where the positioning service function sends a downlink positioning measurement request to the first radio distributed unit function, or based on the embodiment where the positioning service function sends a downlink positioning measurement request not only to the first radio distributed unit function but also to the second radio distributed unit function, in order to achieve downlink positioning measurement of the terminal, in an optional embodiment, the method of this application further includes:

[0423] Receive the location response message sent by the terminal;

[0424] Receive downlink positioning measurement results sent by the terminal;

[0425] It should be noted that after receiving the downlink positioning resource configuration information from the first wireless distributed unit function, the terminal receives the downlink positioning reference signal sent by the first wireless distributed unit function on the downlink positioning resource corresponding to the downlink positioning resource configuration information, performs downlink positioning measurement according to the downlink positioning reference signal, and obtains downlink positioning measurement result 1.

[0426] After receiving downlink positioning resource configuration information (configuration information of the first downlink positioning resource) from the first wireless distributed unit function and downlink positioning resource configuration information (configuration information of the second downlink positioning resource) from the second wireless distributed unit function, the terminal receives the downlink positioning reference signal sent by the first wireless distributed unit function on the downlink positioning resource corresponding to the configuration information of the first downlink positioning resource, performs downlink positioning measurement according to the downlink positioning reference signal, and obtains downlink positioning measurement result 1; and receives the downlink positioning reference signal sent by the second wireless distributed unit function on the downlink positioning resource corresponding to the configuration information of the second downlink positioning resource, performs downlink positioning measurement according to the downlink positioning reference signal, and obtains downlink positioning measurement result 2.

[0427] The location information of the terminal is determined based on the downlink positioning measurement results.

[0428] Specifically, the location service function calculates the terminal's location information based on downlink location measurement result 1. Alternatively, the locator calculates the terminal's location information based on downlink location measurement result 1 and downlink location measurement result 2. For a clearer understanding of the downlink location measurement between the wireless distributed unit function and the location service function, please refer to Embodiment 3 above.
