A measurement method, device and computer-readable storage medium

This application claims priority to the Chinese patent application filed with the China Patent Office on August 9, 2022, with application number 202210949939.7 and the application title "A measurement method, device and computer-readable storage medium", the entire content of which is incorporated by reference incorporated in this application.

Technical field

The present application relates to the field of communication technology, and in particular, to a measurement method, device and computer-readable storage medium.

Background technique

Wireless spectrum resources are limited resources. Generally speaking, the use of wireless spectrum resources requires a license (usually called a license) issued by the government of the country or region where it is located. However, with the increasing number of access network equipment, limited spectrum resources are difficult to meet the huge demand for data services. In order to solve this problem, Long Term Evolution (LTE) and New Radio (NR) have respectively launched Licensed-Assisted Access (LAA) for use in unlicensed frequency bands and Licensing-Assisted Access (LAA) for use in unlicensed frequency bands. Working New Radio Unlicensed (NR-U) system. Access to license-free spectrum channels needs to meet regulatory rules, that is, listen-before-talk (LBT) must be performed before accessing the channel. The essence of the LBT mechanism is a channel access rule. The terminal device needs to listen to whether the channel is idle before accessing the channel and starting to send data. If the channel has been idle for a period of time, the terminal device can occupy the channel.

Since the actual locations of the terminal equipment and the base station are different, for example, the base station may be located outdoors and the terminal equipment may be located indoors. Terminal equipment is easily affected by Wireless-Fidelity (Wi-Fi) signals, Bluetooth signals, etc. on unlicensed spectrum channels indoors, causing the base station and terminal equipment to perform LBT or load on the same unlicensed spectrum channel. The results of the judgment are different. Terminal equipment may experience frequent LBT failures and is unable to occupy the channel, causing uplink data transmission to be blocked or terminal equipment to be unable to access the cell.

In a first aspect, this application provides a measurement method, which is applied to a first access network device. The method includes: receiving a measurement result of at least one first channel from a terminal device, where the measurement result includes a load of at least one first channel. In this case, the first channel is a license-free spectrum channel; the target channel is determined from the at least one first channel based on the measurement result of the at least one first channel, and the target channel is used for data transmission between the terminal equipment and the first access network equipment, Or the target channel is used for terminal equipment to randomly access the target access network equipment.

The load of one channel is lower than the load of other channels of the plurality of second channels except the first channel. Based on this implementation, the first access network device can determine a lightly loaded channel from the plurality of second channels as the first channel through the measurement results of the plurality of second channels, because the subsequent determination of the target channel is based on at least one third channel. The target channel is determined in a channel. Therefore, the target channel is idle for the first access network equipment and is also idle for the terminal equipment, thereby avoiding the load inconsistency of the channel on both sides of the first access network equipment and the terminal equipment. , causing the first access network device to judge that the channel can be used to send downlink data, but there may be other devices occupying the channel around the terminal device, causing greater interference and reducing the success rate of the terminal device in receiving data.

Based on this implementation, it is beneficial to enable the first access network device to select a more appropriate target channel.

In a possible implementation, the target channel is used for terminal equipment to randomly access the target access network equipment. Before sending the first indication information to the terminal equipment, the method further includes: receiving data from at least one second access network. Unlicensed spectrum channel occupancy information of the device; receiving neighboring cell measurement information from the terminal equipment. The neighboring cell measurement information is used to indicate that the difference between the neighboring cell signal quality and the local signal quality is greater than the first threshold and/or the neighboring cell signal quality is greater than the third threshold. Two thresholds: determine the target access network device from at least one second access network device based on the neighbor cell measurement information; determine at least one first channel based on the neighbor cell measurement information and the license-free spectrum channel occupancy information of the target access network device. Based on this implementation, the first access network device can select an idle channel as the first channel through the license-free spectrum channel occupancy information of the target access network device, because the subsequent target channel is determined from at least one first channel. The target channel, therefore, the target channel is idle for the target access network device and also for the terminal device, thereby avoiding the random access failure of the terminal device due to multiple LBT failures, thereby improving the random access of the terminal device. Success rate.

FIG. 2A shows a communication network architecture in the communication system provided by this application, and the embodiments provided subsequently may be applicable to this architecture. Access network device 1 is the source access network device of the terminal device (or called working access network device, or service access network device), and access network device 2 is the target access network device of the terminal device (or called (standby access network equipment), that is, the access network equipment that provides services to terminal equipment after switching. "Handover" refers to the handover of access network equipment that provides services to terminal equipment, and is not limited to "cell handover". The "switching" may refer to a switching caused by changes in the access network equipment that provides services to the terminal equipment. For example, when the source access network device of a terminal device fails, the backup access network device provides services for the terminal device. For another example, when a terminal device switches from a source access network device to communicate with another access network device, the switched target access network device provides services for the terminal device. The cells accessed by the terminal equipment before and after the handover may change or remain unchanged. It can be understood that the backup access network device is a relative concept. For example, with respect to one terminal device, access network device 2 is the backup access network device of access network device 1, but with respect to another terminal device, access network device 2 is the backup access network device of access network device 1. , access network device 1 is the backup access network device of access network device 2.

The access network device 1 and the access network device 2 may be two different devices. For example, the access network device 1 and the access network device 2 are two different access network devices. Access network device 1 and access network device 2 may also be two sets of functional modules in the same device. The functional module may be a hardware module, a software module, or a hardware module and a software module. For example, the access network device 1 and the access network device 2 are located in the same access network device and are two different functional modules in the access network device. In one implementation manner, the access network device 1 and the access network device 2 are not transparent to the terminal device. When the terminal device interacts with the corresponding access network device, it can know which access network device it is interacting with. In another implementation manner, the access network device 1 and the access network device 2 are transparent to the terminal device. The terminal device can communicate with the access network device, but does not know which of the two access network devices it is interacting with. In other words, for terminal equipment, it may be considered that there is only one access network equipment. In the subsequent description, the access network device may be access network device 1 or access network device 2.

Figure 2B shows another communication network architecture in the communication system provided by this application. As shown in Figure 2B, the communication system includes a core network (new core) and a radio access network (radio access network, RAN). The access network equipment (for example, base station) in the RAN includes a baseband device and a radio frequency device. The baseband device can be implemented by one or more nodes, and the radio frequency device can be implemented remotely from the baseband device, independently, integrated into the baseband device, or partially remote and partially integrated into the baseband device. The access network equipment in the RAN can be an access network equipment with a split architecture of centralized unit (CU) and distributed unit (DU). Multiple DUs can be centrally controlled by one CU, and one DU can also Multiple CUs can be connected (not shown in the figure). CU and DU can be connected through an interface, for example, the F1 interface. CU and DU can be divided according to the protocol layer of the wireless network. For example, one possible division method is: CU is used to execute the radio resource control (RRC) layer, service data adaptation protocol (SDAP) layer and packet data convergence layer protocol (packet data convergence). protocol (PDCP) layer, and DU is used to perform functions of the radio link control (RLC) layer, media access control (media access control, MAC) layer, physical layer, etc. It can be understood that the division of CU and DU processing functions according to this protocol layer is only an example, and they can also be divided in other ways. For example, a CU or DU can be divided into functions with more protocol layers. For another example, CU or DU can also be divided into partial processing functions with protocol layer. In one design, part of the functions of the RLC layer and the functions of the protocol layer above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layer below the RLC layer are set in the DU. In another design, the functions of CU or DU can also be divided according to service types or other system requirements. For example, divided by delay, the processing time needs to meet the delay requirements The functions that do not need to meet the delay requirements are set in DU, and the functions that do not need to meet the delay requirements are set in CU. In another design, the CU may also have one or more functions of the core network. One or more CUs can be set centrally or separately. For example, CU can be set up on the network side to facilitate centralized management. DU can have multiple radio frequency functions, and the radio frequency functions can also be set remotely.

Figure 2C shows another communication network architecture in the communication system provided by this application. Compared with the architecture shown in Figure 2B, the control plane (CP) and user plane (UP) of the CU can also be separated and implemented into different entities, namely the control plane CU entity (CU-CP entity) and the user plane CU entity. (CU-UP entity). In this network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU may directly encapsulate the signaling through the protocol layer and transparently transmit it to the terminal device or CU without parsing the signaling. In this network architecture, the CU is divided into access network equipment on the RAN side. In addition, the CU can also be divided into access network equipment on the CN side. This application does not limit this.

In the embodiments of this application, the device used to implement the functions of the access network equipment may be the access network equipment, or may be a device that can support the access network equipment to implement the functions, such as a chip system or a device that can implement the functions of the access network equipment. As a combination of devices and components, the device can be installed in access network equipment. In the technical solution provided by the embodiment of the present application, the technical solution provided by the embodiment of the present application is described, taking the device for realizing the functions of the access network device as an access network device as an example.

In order to better understand the embodiments of the present application, the relevant concepts involved in the embodiments of the present application are first introduced below:

1. Unlicensed spectrum

Unlicensed spectrum (also known as unlicensed spectrum) can be understood as a physical frequency band that is open to an indefinite number of independent users and can be used directly without registration or separate permission. License-free spectrum belongs to wireless spectrum resources. Wireless spectrum resources also include licensed spectrum. Licensed spectrum is a physical frequency band that requires exclusive use rights, authorization or permission before it can be used. Normally, the wireless spectrum resources used by terminal devices are licensed spectrum. However, with the increasing number of access network equipment, limited spectrum resources are difficult to meet the huge demand for data services. In order to solve this problem, Long Term Evolution (LTE) and New Radio (NR) have respectively launched Licensed-Assisted Access (LAA) for use in unlicensed frequency bands and Licensing-Assisted Access (LAA) for use in unlicensed frequency bands. Working New Radio Unlicensed (NR-U) system. Access to license-free spectrum channels needs to meet regulatory rules, that is, listen-before-talk (LBT) must be performed before accessing the channel. The essence of the LBT mechanism is a channel access rule. The terminal device needs to listen to whether the channel is idle before accessing the channel and starting to send data. If the channel has been idle for a period of time, it can occupy the channel.

Based on the above introduction to the license-free spectrum, before the terminal device transmits uplink, the access network device needs to deliver specific uplink resource information. The uplink resource information includes the uplink channel used for transmission and the transmission time. The terminal device will perform LBT on the designated uplink channel before uplink transmission. When the LBT detection result is idle, the channel can be occupied for uplink transmission. If the terminal device performs handover between cells and needs to perform Random Access Channel (RACH) access in the target cell, the target access network device of the target cell sends the RACH resource information to the target cell through the source access network device. Terminal equipment, when the LBT detection result of the terminal equipment on a RACH channel is idle, it can send RACH related information on the RACH channel.

Since the actual locations of the terminal equipment and the access network equipment are different, for example, the access network equipment may be located outdoors and the terminal equipment may be located indoors. Terminal equipment is easily affected by Wireless-Fidelity (Wi-Fi), Bluetooth, etc. on unlicensed spectrum channels indoors, causing access network equipment and terminal equipment to perform LBT or load judgment on the same unlicensed spectrum channel. The results are different. Therefore, it may happen that the unlicensed spectrum channel that the access network equipment prefers to ensure uplink transmission and that the access network equipment thinks is lightly loaded may actually be a heavily loaded channel for the terminal equipment, so the terminal equipment may experience frequent LBT failures. The channel cannot be occupied, resulting in problems such as blocked uplink data transmission or the inability of terminal equipment to access the community.

In order to avoid the terminal equipment failing to occupy the channel multiple times in a row, this application proposes a measurement method, see Figure 3. As shown in Figure 3, the measurement method includes the following steps 301 to 303. The execution subject of the method shown in Figure 3 may be the terminal device and the first access network device, or the execution subject may be a chip in the terminal device or a chip of the first access network device. Figure 3 takes the terminal device and the first access network device as the execution subject of the method as an example for illustration. The embodiment of the present application does not limit the execution subject of the measurement method. in:

301. The terminal device measures the load condition of at least one first channel and obtains a measurement result of at least one first channel. The first channel is a license-free spectrum channel.

In the embodiment of this application, the first channel is a license-free spectrum channel. If the terminal device needs to occupy the first channel, it needs to perform LBT first, and the first channel can be occupied only after the LBT is successful. The terminal equipment measuring the load condition of at least one first channel means that the terminal equipment measures the energy of the first channel within a certain period of time. If the energy of the first channel is always greater than the preset threshold within the measurement time, it means that the load of the first channel is heavy and there may be other devices occupying the first channel. If the energy of the first channel is always less than the preset threshold during the measurement time, it means that the first channel is lightly loaded and is in an idle state. The measurement method of the first channel by the terminal device includes but is not limited to Radio Resource Management (RRM) measurement, Minimization of drive tests (MDT) measurement, etc., which are not limited in the embodiments of this application.

The measurement method of the first channel by the terminal device may be periodic measurement or continuous measurement. Periodic measurement refers to measuring once every one cycle. For example, the terminal device measures the first channel every 5 seconds. The measurement time is 100 milliseconds. This method continues for 5 minutes. Continuous measurement refers to measurement without interruption. For example, the terminal device continuously measures the first channel within 5 minutes.

Optionally, the terminal device may adopt a specific measurement method for part of the first channel. Specifically, if the average energy of the third channel is higher than the third threshold, the measurement time of the third channel is extended to obtain the measurement result of the third channel, where the third channel is one of at least one first channel. The third threshold may be configured by the terminal device, or may be configured by the first access network device connected to the terminal device. Among them, the terminal equipment extending the measurement time of the third channel can refer to extending the time for continuous measurement of the third channel. For example, channels other than the third channel only need to continue to measure for 5 minutes, while the third channel needs to continue to measure for 6 minutes. minutes; or, it can also refer to shorter periodic measurements of the third channel. For example, the terminal equipment measures channels other than the third channel in a manner of measuring every 5 seconds, while the measurement of the third channel The method is to measure once every 2 seconds. Based on this implementation method, extending the measurement time of the third channel will help the terminal equipment obtain more accurate measurement results for the heavily loaded channel. In addition, it can also reduce the measurement time for the lightly loaded channel and reduce Energy loss of terminal equipment.

In the embodiment of the present application, the measurement result of the at least one first channel is used to determine the target channel. The target channel is used for data transmission between the terminal equipment and the first access network equipment, or the target channel is used for random access of the terminal equipment. Target access network equipment. The first access network device refers to the access network device connected to the terminal device, and the target access network device refers to the access network device corresponding to the target cell when the terminal device triggers cell handover. The target channel may be determined by the first access network device, the terminal device sends the measurement result of the at least one channel to the first access network device, and the first access network device determines the target channel based on the measurement result. Alternatively, if the target channel is used for the terminal device to randomly access the target access network device, the target channel may be determined by the target access network device, and the terminal device sends the measurement result of the at least one channel to the first access network device. network equipment, the first access network equipment forwards it to the target access network equipment, and the target access network equipment determines the target channel based on the measurement results. The embodiment of this application does not limit the device for determining the target channel. Based on this method, the terminal device pre-measures at least one first channel before performing data transmission or random access to obtain a measurement result. The measurement result of the first channel is used to determine an idle target channel. The target channel is Perform data transmission or random access on the terminal equipment, thereby avoiding the situation where the terminal equipment fails to occupy the channel multiple times in a row, causing the uplink data transmission to be blocked or unable to access the cell.

The measurement result of the first channel may include one or more of the following information: the average energy detection result of the first channel, the proportion of time when the energy of the first channel is higher than the preset threshold, and other standard types using the first channel. wait. The proportion of time that the energy of the first channel is higher than the preset threshold refers to the ratio between the time that the energy of the first channel is higher than the preset threshold and the total time of measuring the first channel. The greater the proportion of time that the energy of the first channel is higher than the preset threshold, the heavier the load on the first channel is, and other devices occupy the channel; the smaller the proportion of time that the energy of the first channel is higher than the preset threshold. , it means that the load of the first channel is lighter and the channel is idle. The preset threshold may be configured by the first access network device, or may be configured by the terminal device itself, which is not limited in the embodiments of the present application. Other standard types using the channel refer to the standard type of the device occupying the first channel when the first channel is occupied by other devices, such as Wi-Fi, Bluetooth, etc. In addition to the information described above, the measurement result of the first channel may also include other information, which is not limited in the embodiment of the present application.

In a possible implementation, before step 301, the first access network device sends first indication information to the terminal device, and correspondingly, the terminal device receives the first indication information from the first access network device. The first indication information is used to instruct the terminal device to measure at least one first channel. After receiving the first indication information, the terminal device may perform measurement according to at least one first channel indicated in the first indication information. Optionally, the first indication information includes a first channel identification (ID) and corresponding frequency point, bandwidth information, etc. Based on this implementation, the first access network device causes the terminal device to measure at least one first channel through the first instruction information, obtains the corresponding measurement result, and determines the load condition of the first channel on the terminal device side, thereby being able to select The idle target channel is used for data transmission or random access by the terminal equipment to prevent the terminal equipment from failing to occupy the channel multiple times in a row, resulting in blocked uplink data transmission or inability to access the cell.

302. The terminal device sends the measurement result of at least one first channel to the first access network device. Correspondingly, the first access network device receives the measurement result of at least one first channel from the terminal device.

303. The first access network device determines the target channel from the at least one first channel based on the measurement result of the at least one first channel.

In this embodiment of the present application, the target channel may be used for data transmission between the terminal device and the first access network device, or the target channel may be used for the terminal device to randomly access the target access network device. The first access network device can determine the load condition of the first channel on the terminal device side based on the measurement results of the first channel, thereby selecting an idle target channel for the terminal device to perform data transmission or random access, to avoid the terminal device from Multiple consecutive failures to occupy the channel may result in uplink data transmission being blocked or inability to access the cell.

Based on the two uses of the target channel described above, the embodiments of this application include the following two situations:

Scenario 1: The terminal device needs to transmit data with the first access network device. In this case, the target channel is used by the end device with the first Access network equipment performs data transmission.

In a possible implementation, before the first access network device sends the first indication information to the terminal device, the method further includes: the first access network device measures load conditions of multiple second channels, and obtains multiple measurement results of a plurality of second channels, the second channel being a license-free spectrum channel; the first access network device determines at least one first channel from a plurality of second channels based on the measurement results of a plurality of second channels, and the first channel The load is lower than the load of other channels in the plurality of second channels except the first channel. The plurality of second channels may refer to all unlicensed spectrum channels on the first access network device side, or may refer to some unlicensed channels on the first access network device side, which is not limited in the embodiments of this application. Based on this implementation, the first access network device can determine a lightly loaded channel from the plurality of second channels as the first channel through the measurement results of the plurality of second channels, because the subsequent determination of the target channel is based on at least one third channel. The target channel is determined in a channel. Therefore, the target channel is idle for the first access network equipment and is also idle for the terminal equipment, thereby avoiding the inconsistency in load of the channel on both sides of the first access network equipment and the terminal equipment. , causing the first access network device to determine that the channel can be used to send downlink data, but there may be other devices occupying the channel around the terminal device, causing greater interference and reducing the success rate of the terminal device in receiving data.

Optionally, the measurement result of the second channel may include an average energy detection result of the second channel and/or a proportion of time in which the energy of the second channel is higher than a preset threshold. The proportion of time when the energy of the second channel is higher than the preset threshold refers to the ratio between the time when the energy of the first channel is higher than the preset threshold and the total time of measuring the first channel. The greater the proportion of time that the energy of the second channel is higher than the preset threshold, the heavier the load on the second channel is, and other devices occupy the channel. The smaller the proportion of time that the energy of the second channel is higher than the preset threshold. , it means that the load of the second channel is lighter and the channel is idle. The measurement results of the second channel may also include other information, which is not limited in the embodiments of the present application.

Optionally, the first access network device may measure the second channel in a periodic manner, for example, measuring the second channel every 5 seconds. Alternatively, the first access network device may measure the second channel through continuous measurement, for example, by continuously measuring the second channel within 2 minutes. Further optionally, the first access network device may also receive unlicensed spectrum channel occupancy information from at least one second access network device, where the unlicensed spectrum channel occupancy information indicates the second access network device's use of the second channel. According to the occupancy status, the second channel used by non-adjacent cells is determined from multiple second channels based on the license-free spectrum channel occupancy information, and the second channel used by non-adjacent cells is measured with priority.

Among them, the license-free spectrum channel occupancy information may include one or more of the following information: the license-free channel ID and frequency used by the second access network device for uplink and downlink; the second access network device on the license-free channel LBT success rate, energy measurement threshold, energy measurement results (that is, the measured average energy) and other information, wherein the energy measurement results may be based on the second access network device or a terminal connected to the second access network device The LBT detection result of the device; the amount of data the second access network device will send on a specific license-free channel, for example, 100M data will be sent on channel 1.

Optionally, a specific implementation manner in which the first access network device determines at least one first channel from multiple second channels based on the measurement results of multiple second channels may be: the first access network device determines at least one first channel based on the service of the terminal device. The type and/or location of the terminal device, measurement results of a plurality of second channels and unlicensed spectrum channel occupancy information from a plurality of second access network devices determine at least one first channel. For example, if the terminal device has high service timeliness and high speed requirements, the first access network device preferentially selects a first channel that is not occupied by neighboring cells and has a light load from a plurality of second channels. In another example, if the terminal device is located at the edge of a cell, the first access network device selects a first channel occupied by a non-neighboring cell.

Optionally, the method further includes: the first access network device receiving unlicensed spectrum channel occupancy information from at least one second access network device, and the first access network device receiving the unlicensed spectrum channel occupancy information from at least one first channel based on the measurement result of the at least one first channel. A specific implementation method for determining the target channel in a first channel is: the first access network device determines the target channel from the at least one first channel based on the unlicensed channel occupancy information of the at least one second access network device and the measurement result of the at least one first channel. Determine the target channel. Exemplarily, the first access network device combines the service type of the terminal device, the measurement result of the at least one first channel and the unlicensed spectrum channel occupancy information from the plurality of second access network devices from the at least one first channel. To determine the target channel, the first access network device prefers a target channel that is not occupied by neighboring cells and has a light load measured by the terminal device for services with high real-time requirements and high rate requirements.

In a possible implementation, the first access network device may also integrate the measurement results of at least one first channel and the measurement results of multiple second channels to obtain the channel information and send it to at least one second access network device. , which is beneficial to enabling the second access network device to understand the channel status of the first access network device. Specifically, the channel information sent by the first access network device to the second access network device may include specific load conditions of one or more channels in the cell, such as average energy detection results at the edge of the cell and the center of the cell. The average channel is Occupation time, and further divides the load situation to distinguish the detection results of terminal equipment or access network equipment. The specific channel may be a channel used by both the current cell and neighboring cells, or may be a channel used by the current cell but not used by neighboring cells, or a channel not used by the current cell but used by neighboring cells. There is no limit to this.

Based on the above description, the first access network device may be an access network device without a split architecture, or may be a DU of an access network device with a split architecture. However, if the first access network device is a DU, after receiving the measurement result of at least one first channel reported by the terminal device, it needs to be sent to the affiliated CU, and then the affiliated CU will perform subsequent target channel confirmation. If the first access network device has a split architecture between CU-CP and CU-UP, the CU-CP needs to determine the target based on the measurement results of the first channel and the unlicensed spectrum occupied channel information of the second access network device. After selecting the channel, the CU-UP specifically generates an uplink scheduling grant (Grant) and sends it to the terminal device. If the first access network device has a split architecture of CU-CP1 and CU-CP2, CP1 may measure the second channel and determine the target channel, and CP2 may generate first indication information instructing the terminal device to measure the first channel.

Scenario 2: The terminal device needs to switch to the target access network device. In this case, the target channel is used for the terminal device to randomly access the target access network device.

In a possible implementation, before the first access network device sends the first indication information to the terminal device, the above method further includes: the first access network device receiving unlicensed spectrum from at least one second access network device. Channel occupancy information; the first access network device receives neighbor cell measurement information from the terminal device, and the neighbor cell measurement information is used to indicate that the difference between the neighbor cell signal quality and the local cell signal quality is greater than the first threshold and/or the neighbor cell signal quality is greater than the second threshold; the first access network device determines the target access network device from at least one second access network device based on the neighbor cell measurement information; the first access network device determines the target access network device based on the neighbor cell measurement information and the target access network device The unlicensed spectrum channel occupancy information determines at least one first channel.

The neighboring cell measurement information includes the measurement results of the terminal equipment on the signal quality of the neighboring cell. The first access network device determines the target access network device from at least one second access network device based on the neighbor cell measurement information, that is, the first access network device determines and selects the cell with the best signal quality based on the neighbor cell measurement information, that is, The cell closest to the terminal device, and the access network equipment corresponding to this cell is the target access network equipment. The neighbor cell measurement information of the first access network device and the unlicensed spectrum channel occupancy information of the target access network device determine at least one first channel, and the first channel is an idle channel on the target access network device side. Based on this implementation, the first access network device can select an idle channel as the first channel through the license-free spectrum channel occupancy information of the target access network device, because the subsequent target channel is determined from at least one first channel. The target channel, therefore, the target channel is idle for the target access network device and also for the terminal device, thereby avoiding the random access failure of the terminal device due to multiple LBT failures, thereby improving the random access of the terminal device. Success rate.

Optionally, the method further includes: the first access network device sending second indication information to the target access network device, where the second indication information indicates the target channel. Wherein, the second indication information may be carried in a handover request (Handover Request) message. Alternatively, the second indication information may also be carried in other messages, or the second indication information may be carried in a new message, which is not limited in the embodiments of the present application. Correspondingly, after the target access network device receives the second indication information sent from the first access network device, the target access network device determines the target channel indicated in the second indication information as a channel for the terminal device to randomly access, The terminal device response information will be sent through the first access network device, and the response information carries the channel identification ID of the target channel and the corresponding frequency and bandwidth information. The response information may be carried in a handover request response (Handover Request ACK) message and sent to the first access network device, and the first access network device sends the response information to the terminal device by configuring the handover information. The response information may also be carried in other messages, or the response information may be carried in a new message, which is not limited in the embodiment of the present application.

Further optionally, the second indication information also indicates the measurement result of at least one first channel. The target access network device may determine whether to select the target channel according to the measurement result of the first channel, and the target access network device may indicate through response information whether to select the target channel or not to select the target channel. If the target access network device does not select the target channel, it can also determine, based on the measurement result of the first channel of the terminal device, that a channel that is idle for both the terminal device and the target access network device is used for the terminal device to perform random access, and then This channel is indicated via the response message. Based on this implementation method, it is helpful for the target access network device to understand the channel status on the terminal device side.

Based on the above description, the first access network device may be an access network device without a split architecture, or may be a DU of an access network device with a split architecture. However, if the first access network device is a DU, after receiving the measurement result of at least one first channel reported by the terminal device, it needs to be sent to the affiliated CU, and then the affiliated CU will confirm the subsequent target channel and communicate with the second access network. Interaction between devices. If the first access network device has a split architecture of CU-CP and CU-UP, the CU-CP needs to determine the first channel that needs to be measured based on the license-free spectrum of the second access network device, and then the CU-UP needs to determine the first channel to be measured based on the terminal The measurement information of at least one first channel of the device completes the confirmation of the target channel. If the first access network device has a split architecture of CU-CP1 and CU-CP2, CP1 may determine the target channel, and CP2 may generate first indication information instructing the terminal device to measure the first channel.

In a possible implementation, the first access network device does not need to determine the target channel from the at least one first channel based on the measurement result of the at least one first channel. The first access network device can determine the target channel after receiving a signal from the terminal device. After measuring the at least one first channel, forward the measurement result of the at least one first channel to the target access network device, and the target access network device determines the target channel for the terminal based on the measurement result of the at least one first channel. The device performs random access. Based on this implementation method, it is beneficial to make the target channel determined by the target access network device be in an idle state for both the terminal device and the target access network device.
