Specific restrictions.

As shown in FIG. 7, it is a schematic flowchart of a terminal positioning method provided by an embodiment of this application. The method may include the following steps:

S101. When the terminal is in an idle state or an inactive state, the positioning device sends paging information, which is used to indicate the trigger state of the terminal, and the trigger state is used to instruct the terminal to send an uplink reference signal for positioning, or Instruct the terminal to measure the downlink reference signal used for positioning.

Correspondingly, the terminal receives the paging message.

When there is no data transmission, the terminal enters an idle state or an inactive state. The idle state means that the access network device serving the terminal sends a radio resource control-release (RRCRelease) message to the terminal and deletes the context of the terminal. After the terminal receives the RRCRelease message, it enters the idle state. The inactive state means that the access network device serving the terminal sends an RRCRelease message containing the SuspendConfig to the terminal and retains the context of the terminal. After the terminal receives the RRCRelease message containing the suspended configuration, it enters the inactive state .

When the positioning device performs terminal positioning, it needs to obtain the uplink reference signal sent by the terminal for uplink positioning, or obtain the measurement result of the terminal on the downlink reference signal for downlink positioning, or obtain the uplink reference signal sent by the terminal for uplink positioning and obtain the terminal Perform downlink positioning on the measurement result of the downlink reference signal. While the terminal is currently in an idle state or in an inactive state, the positioning device can send a positioning request to the AMF or the access network device registered by the terminal, and the AMF or the access network device registered by the terminal sends paging information to the terminal.

The paging information can be carried in a paging message (paging message), and can also be carried in the scheduling information of the paging message. The paging information is used to indicate the trigger state of the terminal, and the trigger state is used to instruct the terminal to send an uplink reference signal for positioning, or to instruct the terminal to measure a downlink reference signal for positioning. The trigger state is specifically a state in the trigger state set, and the trigger state set includes one or more of the following trigger states: no trigger; trigger the transmission of one or more uplink reference signal sets; trigger one or more downlink Reference signal set measurement; stop the transmission of one or more uplink reference signal sets; stop the transmission of all uplink reference signal sets; stop the measurement of one or more downlink reference signal sets; stop the measurement of all downlink reference signal sets; trigger pair Reporting the measurement results of one or more downlink reference signal sets; triggering the reporting of the first information; determining the actions of the terminal according to other triggering states, etc.

The terminal receives the paging information, and executes the operation indicated by the trigger state according to the trigger state indicated by the paging information. For example, the paging information includes 2 bits. If the bit value of the paging information is 00, the corresponding trigger state is not triggered, and the terminal does not send the uplink reference signal, and does not perform the measurement of the downlink reference signal; for another example, if If the bit value of the paging information is 01, the corresponding trigger state is to trigger the transmission of one or more uplink reference signal sets, and the terminal sends the above one or more uplink reference signal sets; for another example, if the bit value of the paging information If it is 10, the corresponding trigger state is to trigger the measurement of one or more downlink reference signal sets, and the terminal performs the measurement of the above-mentioned one or more downlink reference signal sets; and so on.

In the aforementioned terminal positioning technology shown in FIG. 2, since it is stipulated that the terminal cannot send an uplink reference signal when it is in an idle state, the positioning technology only supports downlink-based positioning and does not support uplink positioning, and the positioning accuracy is low. In this embodiment, the paging information can trigger the terminal to send uplink reference signals for positioning, or trigger the terminal to measure downlink reference signals for positioning, or trigger the terminal to send uplink reference signals for positioning and measurement. Therefore, the terminal can measure the downlink reference signal for downlink positioning; it can also send an uplink reference signal for uplink positioning, thereby improving the accuracy of positioning.

Further, before the positioning device sends paging information to the terminal, the positioning device can also obtain the configuration information of the downlink reference signal of the access network device of the serving terminal and the neighboring cell access network device, and obtain the access of the serving terminal The configuration information of the uplink reference signal of the network device. And when the terminal is in the connected state, the positioning device may send the configuration information of the downlink reference signal or the configuration information of the uplink reference signal to the terminal.

S102: The terminal measures the downlink reference signal according to the configuration information of the downlink reference signal.

According to the trigger state indicated by the paging information, if the indicated trigger state triggers the measurement of one or more downlink reference signal sets, the terminal measures the one or more downlink reference signal sets. Specifically, the access network device serving the terminal and the neighboring cell access network device send the downlink reference signal at the time-frequency resource location configured by the configuration information of the downlink reference signal, and the terminal receives the above-mentioned downlink reference signal at the time-frequency resource location. The downlink reference signal includes synchronization signal/physical broadcast signal block (SS/PBCH block), positioning resource signal (positioning resource signal, PRS), etc.

Specifically, for the downlink reference signal sent by any TRP of the access network device serving the terminal or the neighboring cell access network device, if a TRP corresponds to a downlink reference signal set, a downlink reference signal set includes one or more downlink reference signals. Reference signal, each downlink reference signal of the TRP downlink reference signal set represents a beam, and the terminal receives the downlink reference signal sent by the TRP on multiple beams and performs measurement to obtain the measurement result of the downlink reference signal.

The measurement result of the downlink reference signal includes one or more of the following measurement quantities: downlink reference signal time difference (DL RSTD), downlink positioning reference signal reference signal received power (downlink positioning reference signal reference signal received power, DL PRS-RSRP), terminal transceiver time difference (UE Rx-Tx time difference), synchronization signal reference signal received power (synchronization signal reference signal received power, SS-RSRP), synchronization signal reference signal received quality (synchronization signal reference signal) receive quality, SS-RSRQ). The downlink reference signal can be measured with one or more of the above measurement quantities.

S103': The terminal sends the uplink reference signal to the access network device according to the configuration information of the uplink reference signal.

Correspondingly, the access network device receives the uplink reference signal according to the configuration information of the uplink reference signal. The access network equipment may be the access network equipment of the service terminal or the neighboring cell access network equipment.

S104. The access network device measures the uplink reference signal to obtain the measurement result of the uplink reference signal.

S105. The access network device sends the measurement result of the downlink reference signal to the positioning device.

Correspondingly, the positioning device receives the measurement result of the uplink reference signal from the access network device.

S103", the terminal device sends the measurement result of the downlink reference signal to the positioning device.

Correspondingly, the positioning device receives the measurement result of the downlink reference signal from the terminal.

The terminal is still in the idle state or inactive state, and the terminal is based on the trigger state indicated by the paging information. If the indicated trigger state triggers the transmission of one or more uplink reference signal sets, the terminal is based on the configuration information of the uplink reference signal Send the uplink reference signal. Specifically, at the time-frequency resource position of the uplink reference signal, the uplink reference signal is sent according to the period of the uplink reference signal, etc. The uplink reference signal includes a sounding resource signal (SRS) and a random access preamble (preamble).

If the paging information triggers the measurement and reporting of the downlink reference signal, the terminal sends the measurement result of the downlink reference signal after obtaining the measurement result of the downlink reference signal.

It is understandable that if the paging information triggers the transmission of the uplink reference signal and the measurement and transmission of the downlink reference signal, the terminal performs the measurement of the downlink reference signal, and sends the measurement results of the uplink reference signal and the downlink reference signal, and accesses the network The device measures the uplink reference signal and sends the measurement result of the uplink reference signal to the positioning device, that is, steps S102 to S105 are executed; if the paging information only triggers the transmission of the uplink reference signal, the terminal sends the uplink reference signal and accesses the network The device measures the uplink reference signal and sends the measurement result of the uplink reference signal to the positioning device, that is, steps S103' to S105 are executed; if the paging information only triggers the measurement and transmission of the downlink reference signal, the terminal performs the downlink reference signal measurement and transmission. Measure and send, that is, perform steps S102 and S103".

S106. The positioning device locates the terminal according to the measurement result of the uplink reference signal or the measurement result of the downlink reference signal.

The positioning device can perform uplink positioning on the terminal after receiving the uplink reference signal measurement result sent by the access network device; or, the positioning device can perform downlink positioning on the terminal after receiving the downlink reference signal measurement result sent by the terminal; or the positioning device can perform downlink positioning on the terminal at the same time. Upon receiving the uplink reference signal measurement result sent by the access network device and the downlink reference signal measurement result sent by the terminal, the terminal can be positioned in the uplink and downlink.

According to the terminal positioning method provided by the embodiments of the present application, the positioning device can trigger the terminal to send the uplink reference signal or perform the measurement of the downlink reference signal through the paging information at any time as needed, and the terminal does not need to send or measure at the specified measurement sending time. In addition, when the terminal is in an idle state or an inactive state, the measurement result of the uplink reference signal or the downlink reference signal can be sent, which saves the power consumption of the terminal; and the positioning device supports the positioning based on the uplink and the downlink, which improves the positioning accuracy.

As shown in FIG. 8, another schematic flow chart of the terminal positioning method provided by this embodiment of the application, the method may include the following steps:

S201: The first access network device sends the configuration information of the uplink reference signal to the positioning device through the AMF, or the first access network device sends the configuration information of the downlink reference signal to the positioning device through the AMF.

Correspondingly, the positioning device receives the configuration information of the uplink reference signal or the configuration information of the downlink reference signal sent by the first access network device. The first access network device is an access network device serving the terminal, and may also be referred to as a serving cell.

In addition, the neighboring cell access network device (not shown in the figure) sends the configuration information of the downlink reference signal to the positioning device through the AMF, and the positioning device receives the configuration information of the downlink reference signal sent by the neighboring cell access network device.

In this embodiment, the positioning device and the terminal have established a connection in the connected state, and the LTE positioning protocol (LTE positioning protocol, LPP) is activated. At the same time, the positioning device and the terminal have already interacted with the terminal positioning capability. For example, the terminal reports that it supports the measurement, reporting, or uplink reference signal transmission of downlink reference signals based on paging triggers. In addition, the positioning device also requests and obtains the physical layer resource configuration from the first access network device, for example, the uplink reference signal configuration.

The first access network device configures the uplink reference signal in advance. The uplink reference signal includes sounding reference signal and random access preamble.

S202: The positioning device sends the configuration information of the downlink reference signal or the configuration information of the uplink reference signal to the terminal.

Specifically, the positioning device sends the configuration information of the downlink reference signal or the configuration information of the uplink reference signal to the terminal through the AMF and the first access network device. The positioning device sends the configuration information of the downlink reference signal or the configuration information of the uplink reference signal to the terminal based on the LPP. The configuration information of the downlink reference signal includes the configuration information of the downlink reference signal sent by the first access network device and the neighboring cell access network device to the positioning device; the configuration information of the uplink reference signal includes the configuration information of the first access network device to the positioning device; The configuration information of the uplink reference signal sent by the positioning device.

Correspondingly, the terminal receives the configuration information of the downlink reference signal or the configuration information of the uplink reference signal.

S203. The positioning device sends measurement request information to the terminal through the AMF and the first access network device.

Correspondingly, the terminal receives the measurement request information. The measurement request information is based on LPP. The measurement request information is used to request the terminal to perform positioning.

Wherein, the measurement request information is used to instruct the terminal to perform one or more of the following operations after receiving the paging information:

Downlink reference signal measurement;

Uplink reference signal transmission;

Report the measurement result of the downlink reference signal;

Report the first information.

This means that the terminal may not perform the above operations immediately after receiving the measurement request information, but postpone the execution of the above operations, and perform the above operations after receiving the paging information.

In addition, the positioning device also configures a trigger state set of the paging information, and the trigger state set is included in the measurement request information. According to the paging information carried in the paging message, or the scheduling information of the paging message (which can be downlink control information (DCI)), or the scheduling information of the paging message and the paging message, the trigger state There are several implementations of collections:

In one implementation, the paging information is carried in the paging message, and the measurement request information includes the first trigger state set. The first trigger state set includes one or more first trigger states.

Wherein, the first trigger state includes one or more of the following trigger states:

Does not trigger; or

Trigger the transmission of one or more uplink reference signal sets; or

Trigger the measurement of one or more downlink reference signal sets; or

Stop the transmission of one or more uplink reference signal sets; or

Stop the transmission of all uplink reference signal sets; or

Stop the measurement of one or more downlink reference signal sets; or

Further, the measurement request information may also include one or more of the following information: the number of measurements of the downlink reference signal, the number of transmissions of the uplink reference signal, and the time between the reporting of the measurement result of the downlink reference signal and the receipt of paging information Time interval. Among them, in order to improve the measurement accuracy of the downlink reference signal, the positioning device may carry the specific downlink reference signal measurement times in the measurement request information. At the same time, in order to improve the measurement accuracy of the uplink reference signal, the positioning device may carry a specific number of transmissions of the uplink reference signal in the measurement request information. In addition, the time interval between the reporting of the measurement result of the downlink reference signal and the receipt of the paging information can be flexibly configured. For example, the terminal device can be configured to measure the downlink reference signal immediately after receiving the paging information, and The downlink reference signal measurement is reported 5 seconds after the paging information, so that the terminal can flexibly measure and report according to its own situation. Accordingly, the terminal can report the first information. The first information includes one or more of the following information: actual transmission times of the uplink reference signal, and index information of the camping cell. The positioning device can accurately obtain the measurement result of the uplink reference signal according to the actual number of transmissions of the obtained uplink reference signal, thereby improving the measurement accuracy of the uplink reference signal. The positioning device can roughly locate the terminal according to the acquired index information of the camping cell, thereby improving the efficiency of terminal positioning.

Exemplarily, the format of the first trigger state set is as follows:

It can be seen that for any trigger state, an operation on one or more reference signal resource sets in the UL-RS-SetId or DL-RS-SetId can be triggered.

It can be understood that the first trigger state in the first trigger state set and the bit value of the paging information have a preset corresponding relationship. The number of configurable first trigger states is the total number of first trigger states minus 1, where a certain first trigger state in the first trigger state set is reserved as non-triggered, corresponding to the bit of the paging information The value is the state of all 0s. For example, according to the configuration sequence of the first trigger state in the first trigger state set, the first trigger state in the first trigger state set is in a one-to-one correspondence with the bit values of the paging information that are not all 0s. For example, the paging information includes 3 bits, 000 means not to trigger; 001 means to trigger the reception of the downlink reference signal set; 010 means to trigger the reception of the downlink reference signal set and trigger the transmission of the uplink reference signal; 011 means to stop the downlink reference signal set Receive; 100 means triggering the reporting of the measurement result of the downlink reference signal; 101 means triggering the transmission of the uplink reference signal set; and so on.

In another implementation, the paging information is carried in the scheduling information of the paging message, and the measurement request information further includes the second trigger state set. The second trigger state set includes one or more second trigger states. The number of second trigger states included in the second trigger state set may be the same as or different from the number of first trigger states included in the first trigger state set; the format of the second trigger state set may be the same as that of the first trigger state set. The format is the same or different.

In another implementation, the paging information is carried in the scheduling information of the paging message and the paging message, and the measurement request information further includes the third trigger state set and the fourth trigger state set. The fourth trigger state set includes one or more fourth trigger states. The format of the fourth trigger state included in the fourth trigger state set may be the same as or different from the number of the first trigger state included in the first trigger state set; the format of the fourth trigger state set may be the same as the format of the first trigger state set Same or different.

Wherein, the third trigger state set includes one or more third trigger states, and the third trigger state includes one or more of the following trigger states:

Does not trigger; or

Determined according to the fourth trigger state; or

Trigger the transmission of one or more uplink reference signal sets; or

Trigger the measurement of one or more downlink reference signal sets; or

Stop the transmission of one or more uplink reference signal sets; or

Stop the transmission of all uplink reference signal sets; or

Stop the measurement of one or more downlink reference signal sets; or

Stop the measurement of all downlink reference signal sets; or

Trigger to trigger the reporting of measurement results of one or more downlink reference signal sets; or

Trigger the reporting of the first information.

Exemplarily, the format of the third trigger state set is as follows:

The difference between this implementation and the above implementation is that the third trigger state set also includes a third trigger state: upToPCH, which means that the scheduling information indicates that the trigger state depends on the fourth trigger state. The fourth trigger state is the trigger state indicated by the paging message carried on the paging channel (paging channel, PCH) mapped to the physical downlink shared channel (PDSCH) scheduled by the scheduling information. That is, the trigger state is determined jointly according to the scheduling information of the paging message and the paging message.

S204. The first access network device sends an RRCRelease message to the terminal.

Correspondingly, the terminal receives the RRCRelease message.

In the case where the terminal has no data transmission or the terminal moves out of the coverage area of the first access network device, the first access network device may send an RRCRelease message to the terminal. This message is used to notify the terminal to release the RRC connection. The terminal enters the idle state.

S205. The AMF notifies all access network devices in a tracking area (tracking area, TA) to send paging information to the terminal.

Correspondingly, the terminal receives the paging information.

Specifically, because the terminal is in an idle state, the RRC connection between the terminal and the first access network device has been disconnected. Therefore, the AMF notifies all access network devices in the TA to send paging information to the terminal. The terminal receives the scheduling information of the paging message, and periodically monitors the paging message at the paging occasion.

Configure the paging information to be carried in the paging message, or the scheduling information of the paging message, or the scheduling information of the paging message and the paging message according to the above measurement request information. The scheduling information of the paging message and the paging message has the following: Kind of realization:

In one implementation, the scheduling information of the paging message is used to determine a physical downlink shared channel (PDSCH). The PCH mapped to the PDSCH carries the paging message. The paging message is used to page the terminal. The paging message also carries the above-mentioned paging information. That is, the paging message is also used to determine a first trigger state, and the first trigger state belongs to the first trigger state set. For example, according to the first trigger state set configured according to the measurement request information, if the bit value corresponding to the paging information is 000, the corresponding trigger state is to trigger the transmission of the uplink reference signal set; if the bit value corresponding to the paging information is 001 , The corresponding trigger state is to trigger the reception of the downlink reference signal set; if the bit value corresponding to the paging information is 010, the corresponding trigger state is to stop the transmission of the downlink reference signal set; if the bit value corresponding to the paging information is 011 , The corresponding trigger state is to stop the reception of the downlink reference signal set; if the bit value corresponding to the paging information is 100, the corresponding trigger state is to trigger the reporting of the measurement result of the downlink reference signal; if the bit value corresponding to the paging information If it is 101, the corresponding trigger state is to trigger the sending of the uplink reference signal set; and so on.

In another implementation, the scheduling information of the paging message is used to schedule the paging message, and the scheduling information of the paging message also carries the above-mentioned paging information. That is, the scheduling information of the paging message is also used to determine a second trigger state, and the second trigger state belongs to the second trigger state set. The paging message is used to page the terminal.

In yet another implementation, the scheduling information of the paging message is used to schedule the paging message, and the paging message is used to page the terminal. And the paging message and the scheduling information of the paging message also carry paging information. That is, the scheduling information of the paging message is also used to determine a third trigger state, which belongs to the third trigger state set; the paging message is also used to determine a fourth trigger state, which belongs to the fourth trigger state Set, the paging information is jointly determined based on the third trigger state and the fourth trigger state.

For example, the third trigger state set includes two third trigger states, wherein the corresponding relationship between the two third trigger states and the bit value of the paging information is: 0 means no triggering, 1 means depending on the paging message (the first Four trigger states). The trigger state in the fourth trigger state set has a preset corresponding relationship with the bit value of the paging information. For example, according to the configuration sequence of the trigger states in the fourth trigger state set, the trigger states in the fourth trigger state set and the bit values of the paging information are in a one-to-one correspondence. For example, the paging information includes 3 bits, 000 means to trigger the transmission of the uplink reference signal set; 001 means to trigger the reception of the downlink reference signal set; 010 means to stop the transmission of the downlink reference signal set; 011 means to stop the reception of the downlink reference signal set; 100 indicates the triggering of the reporting of the measurement result of the downlink reference signal; 101 indicates the triggering of the transmission of the uplink reference signal set; and so on. Then, if the bit value corresponding to the scheduling information of the paging message is 0, the terminal can determine not to trigger any operation regardless of the bit value corresponding to the paging message; if the bit value corresponding to the scheduling information of the paging message is 1, the paging message If the bit value corresponding to the call message is 001, the terminal determines to trigger the reception of the downlink reference signal set; and so on.

S206: The terminal measures the downlink reference signal according to the configuration information of the downlink reference signal.

Taking the paging information carried in the scheduling information of the paging message as an example, the terminal receives the scheduling information of the paging message, and executes what is indicated by the first trigger state according to the first trigger state indicated by the scheduling information of the paging message operate. For example, if the first trigger state is not triggering, the terminal does not send uplink reference signals and does not perform downlink reference signal measurement; for another example, if the first trigger state is to trigger the transmission of one or more uplink reference signal sets, then The terminal sends the aforementioned one or more uplink reference signal sets; for another example, if the first trigger state is to trigger the measurement of one or more downlink reference signal sets, the terminal performs the measurement of the aforementioned one or more downlink reference signal sets; etc. .

According to the first trigger state indicated by the scheduling information of the paging message, the terminal will trigger the measurement of one or more downlink reference signal sets if the indicated first trigger state is Take measurements. Specifically, the first access network device and the neighboring cell access network device send the downlink reference signal at the time-frequency resource location configured by the configuration information of the downlink reference signal, and the terminal receives the aforementioned downlink reference signal at the time-frequency resource location. The downlink reference signal includes SS/PBCH block, PRS, etc.

Specifically, for the downlink reference signal sent by any TRP of the first access network device or the neighboring cell access network device, if one TRP corresponds to one downlink reference signal set, one downlink reference signal set includes one or more downlink reference signals Each downlink reference signal in the downlink reference signal set of the TRP represents a beam, and the terminal receives the downlink reference signal sent by the TRP on multiple beams and performs measurement to obtain the measurement result of the downlink reference signal.

The measurement result of the downlink reference signal includes one or more of the following measurement quantities: downlink reference signal time difference, downlink positioning reference signal reference signal received power, terminal transceiver time difference, synchronization signal reference signal received power, synchronization signal reference signal received quality . The downlink reference signal can be measured with one or more of the above measurement quantities.

S207": The terminal sends the uplink reference signal according to the configuration information of the uplink reference signal.

Correspondingly, the access network device receives the uplink reference signal. The access network equipment may be all access network equipment in the TA. All the access network devices in the TA may include the above-mentioned first access network device, or may not include the above-mentioned first access network device. In this example, it is described that all the access network devices in the TA may include the above-mentioned first access network device.

Similarly, other access network devices in the TA also measure the uplink reference signal to obtain the measurement result of the uplink reference signal.

S209. The first access network device sends the measurement result of the uplink reference signal to the positioning device.

Correspondingly, the positioning device receives the measurement result of the above-mentioned uplink reference signal.

According to the first trigger state indicated by the scheduling information of the paging message, if the indicated first trigger state triggers the transmission of one or more uplink reference signal sets, the terminal Send the uplink reference signal according to the configuration information of the uplink reference signal. Specifically, at the time-frequency resource position of the uplink reference signal, the uplink reference signal is sent according to the period of the uplink reference signal, etc. The uplink reference signal includes sounding reference signal and random access preamble.

If the paging information triggers the measurement and reporting of the downlink reference signal, the terminal sends the measurement result of the downlink reference signal after obtaining the measurement result of the downlink reference signal.

It is understandable that if the scheduling information of the paging message triggers the transmission of the uplink reference signal and the measurement and transmission of the downlink reference signal, the terminal performs the measurement of the downlink reference signal, and sends the uplink reference signal to the access network device and the positioning The measurement result of the downlink reference signal of the device, and the measurement result of the access network device measuring the uplink reference signal and sending the uplink reference signal to the positioning device, that is, perform steps S206 to S209; if the scheduling information of the paging message only triggers the uplink reference When the signal is sent, the terminal sends the uplink reference signal, the access network device measures the uplink reference signal, and sends the measurement result of the uplink reference signal to the positioning device, that is, steps S207" to S209 are performed; if the scheduling information of the paging message is only When the measurement and transmission of the downlink reference signal are triggered, the terminal performs the measurement and transmission of the downlink reference signal, and executes the transmission of the measurement result of the downlink reference signal in S206 and S207'.

In addition, the terminal can also report the above-mentioned first information.

Since the time-frequency resource of the uplink reference signal has been configured, the terminal can use the time-frequency resource to send the uplink reference signal.

The terminal also sends the measurement result of the downlink reference signal or the first information in the following manner:

In one implementation, the terminal sends the measurement result of the downlink reference signal, or the first information, through the message 3 of the 4-step random access that is not in the connected state. Among them, for contention-based random access, when the terminal is idle, it can perform random access through 4 steps: the terminal sends message 1 (preamble); the terminal receives the random access response sent by the access network device (random access response) , RAR), that is, message 2; the terminal sends an uplink message on the allocated uplink resources according to the RAR's instructions, that is, message 3; the access network device receives the terminal’s uplink message and returns a conflict resolution message to the successfully connected terminal, That is message 4.

In yet another implementation, the terminal sends the measurement result of the downlink reference signal, or the first information, through the message A of the 2-step random access that is not in the connected state. Among them, the 2-step random access means that the terminal sends the above-mentioned 4-step random access message 1 and message 3 together as one message (ie message A), and the access network equipment sends the above-mentioned 4-step random access message 2 and message together. 4 is sent together as one message (ie message B). In this embodiment, the measurement result of the downlink reference signal or the first information can be carried in the message A without entering the connected state.

In yet another implementation, the terminal sends the measurement result of the downlink reference signal or the first information through the pre-configured physical layer uplink shared channel resource that has not entered the connected state.

If the uplink reference signal sent by the terminal is detected, the uplink reference signal is measured to obtain the measurement result of the uplink reference signal. The access network device in the TA sends the measurement result of the uplink reference signal to the positioning device.

The access network device where the terminal resides in the TA receives the measurement result of the downlink reference signal sent by the terminal, and sends the measurement result of the downlink reference signal to the positioning device through the AMF.
