[0223] The embodiments of this application are described below with reference to Embodiment 1, Embodiment 2 and Embodiment 3.

[0224] Example 1

[0225] During the discovery phase or the direct link establishment phase, the first terminal sends the first information. The first terminal can enable the first communication device to call the first terminal's ranging and / or secondary link positioning service to obtain measurement information and / or measurement results between the target terminals.

[0226] See Figure 6 The specific steps include:

[0227] Step 1: During the discovery phase or the direct link establishment phase, the first terminal sends first information to the first communication device #1, the first communication device #2 and / or the first communication device #3. The first information is used to instruct the first terminal to provide location-related services to the first communication device. The first communication device can call the ranging and / or secondary link positioning services of the first terminal to obtain measurement information and / or measurement results between the target terminals.

[0228] Optionally, the first information can be included in the discovery message or the direct establishment request message.

[0229] The first communication device #1, the first communication device #2 and / or the first communication device #3 listen to / receive the first information sent by the first terminal, and the first communication device #1, the first communication device #2 and / or the first communication device #3 determine whether to invoke the ranging and / or secondary link positioning service of the first terminal based on the content of the first information.

[0230] Optionally, the first communication device #1, the first communication device #2, and / or the first communication device #3 determine whether to invoke the ranging and / or secondary link positioning service of the first terminal based on at least one of the following:

[0231] (1) Does the target terminal list in the first information include the identifier of the target terminal that the first communication device #1, the first communication device #2 and / or the first communication device #3 wants to obtain measurement information / or measurement results?

[0232] For example, the first communication device #2 determines that the target terminal list in the first information includes the identifier of the target terminal that the first communication device #2 wants to obtain measurement information / or measurement results from.

[0233] (2) Whether the capability information of the first terminal meets the requirements of the first communication device #1, the first communication device #2 and / or the first communication device #3;

[0234] For example, the first communication device #2 determines that the capability information of the first terminal meets the requirements of the first communication device #2.

[0235] (3) Whether the measurement accuracy meets the requirements of the first communication device #1, the first communication device #2 and / or the first communication device #3.

[0236] For example, the first communication device #2 determines that the measurement accuracy meets the requirements of the first communication device #2.

[0237] Step 2: The first communication device #2 determines to invoke the ranging and / or secondary link positioning service of the first terminal, and sends a direct establishment request or a direct establishment reply message to the first terminal.

[0238] Optionally, the direct establishment request or direct establishment response message includes a first ranging / secondary link positioning request.

[0239] Example 2: The first communication device calls the ranging and / or secondary link positioning service of the first terminal.

[0240] See Figure 7 The specific steps include:

[0241] Step 1: The first communication device sends a first request (or is described as a first ranging and / or secondary link positioning request) to the first terminal, and calls the ranging and / or secondary link positioning service of the first terminal to obtain the location of the target terminal, the measurement information between the target terminals and / or the measurement results between the target terminals.

[0242] Optionally, the first request can be included in existing PC5-S signaling, such as in a direct establishment request / direct link update request message, or by sending the first request using dedicated signaling.

[0243] Step 2: The first terminal receives the first request sent by the first communication device and performs authentication for the first communication device to call the ranging and / or secondary link positioning services of the first terminal:

[0244] One implementation involves the first terminal determining, based on configuration information, whether the first communication device is authorized to invoke the first terminal's ranging and / or secondary link positioning services.

[0245] In another implementation, the first terminal determines whether the first communication device is authorized to invoke the first terminal's ranging and / or secondary link positioning services based on network-side authentication instructions, such as... Figure 7 As shown, the first terminal sends a second request (or is described as a first ranging / secondary link positioning service open authentication request) to the second communication device.

[0246] Step 3: The second communication device receives the second request and sends a third request (or describes it as a second ranging / sublink positioning service open authentication request) to the third communication device.

[0247] Step 4: The third communication device receives the third request and performs a ranging / secondary link positioning service authentication process on the first communication device and / or the target terminal (steps 4a and 4b). For example, based on at least one of the following: the first communication device's subscription information, the first communication device's authorization information, the operator's policy, the local policy, the target terminal's subscription information, and the target terminal's authorization information, it determines whether the first communication device can call the first terminal's ranging and / or secondary link positioning service.

[0248] For example, the third communication device authenticates whether the first communication device is authorized to call the ranging and / or secondary link positioning services of the first terminal, and the third communication device authenticates whether the target terminal allows the first terminal to provide ranging and / or secondary link positioning services.

[0249] Step 5: The third communication device sends the twelfth message (or described as a reply to the second ranging / secondary link positioning service open authentication request) to the second communication device. The twelfth message is used to indicate the authentication information of the third communication device on whether the first communication device has the ability to call the location-related services of the first terminal.

[0250] Step 6: After receiving the twelfth information, the second communication device sends the thirteenth information (or describes it as a reply to the first ranging / secondary link positioning service open authentication request) to the first terminal. The thirteenth information is used to indicate the authentication information of the third communication device on whether the first communication device has the ability to call the location-related services of the first terminal.

[0251] Step 7: The first terminal receives the thirteenth message and authorizes the first communication device to invoke the first terminal's ranging and / or secondary link positioning service. If the request type of the first request in step 1 is type 1 (immediate measurement request), then the first terminal performs ranging and / or secondary link positioning services between the target terminals.

[0252] Optionally, the ranging and / or secondary link positioning services performed by the first terminal between target terminals include at least one of the following:

[0253] (1) Negotiated measurement configuration, which may include at least one of the following: (a) characteristics of the position measurement reference signal, such as the period and power of the position measurement reference signal; (b) the position information of the terminal.

[0254] (2) Detect or receive the position measurement reference signal of the target terminal, and obtain / determine the measurement information and / or measurement results based on the position measurement reference signal.

[0255] Step 8: The first terminal sends a direct establishment reply message / direct link update reply message, which carries a first ranging secondary link positioning service reply message to the first communication device. Optionally, the direct establishment reply message / direct link update reply message carries a first ranging secondary link positioning service reply message, which contains measurement information and / or measurement results.

[0256] Optionally, the measurement information includes at least one of the following: the distance between target terminals, the angle between target terminals, and the position information of the target terminals; the measurement result includes at least one of the following: the distance between target terminals and the angle between target terminals.

[0257] Example 3

[0258] The first terminal performs ranging and / or secondary link positioning services between target terminals based on the event trigger, obtains measurement information and / or measurement results, and feeds them back to the first communication device.

[0259] See Figure 8 The specific steps are as follows:

[0260] Step 1: The request type of the first request is the second type (delayed measurement request). The second type is used to instruct the first terminal to send measurement information and / or measurement results within a second time period and when a specific event is met. That is, based on the specific event trigger (event detected), the first terminal performs ranging and / or secondary link positioning services between target terminals, obtains measurement information and / or measurement results, and feeds them back to the first communication device.

[0261] Step 2: The first terminal performs ranging and / or secondary link positioning services between target terminals.

[0262] Optionally, the ranging and / or secondary link positioning services performed by the first terminal between target terminals include at least one of the following:

[0263] (1) Negotiated measurement configuration, which may include at least one of the following: (a) characteristics of the position measurement reference signal, such as the period and power of the position measurement reference signal; (b) the position information of the terminal.

[0264] (2) Detect or receive the position measurement reference signal of the target terminal, and obtain / determine the measurement information and / or measurement results based on the position measurement reference signal.
