Description

Measurement method, device and computer readable storage medium

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a measurement method, a measurement device, and a computer readable storage medium.

Background

Radio spectrum resources belong to a limited resource, and in general, use of radio spectrum resources requires acquisition of a license (also commonly referred to as a license plate) issued by a government in the country or region. But with the increasing proliferation of access network devices, limited spectrum resources are difficult to meet the huge data service requirements. To address this problem, long term evolution (Long Term Evolution, LTE) and New air interface (NR) have proposed a Licensed-Assisted Access (LAA) system for use in unlicensed bands and a New air interface (New Radio Unlicensed, NR-U) system for operation in unlicensed bands, respectively. The unlicensed spectrum channel needs to be accessed by satisfying regulatory rules, i.e., listen-Before-Talk (LBT) Before the channel is accessed. The nature of the LBT mechanism is a channel access rule where a terminal device needs to listen to a channel for idle before accessing the channel and starting to send data, and can occupy the channel if it has remained idle for a period of time.

Since the locations of the terminal device and the base station are not identical in practice, it is possible that the base station is located outdoors and the terminal device is located indoors, for example. Terminal equipment is easily influenced by Wireless-Fidelity (Wi-Fi) signals, bluetooth signals and the like on Unlicensed spectrum channels indoors, so that LBT or load judgment results of the same Unlicensed spectrum channels are different between a base station and the terminal equipment. The terminal equipment may have the problems that the LBT frequently fails and cannot occupy the channel, so that uplink data transmission is blocked or the terminal equipment cannot access the cell.

Disclosure of Invention

The application provides a measuring method, a measuring device and a computer readable storage medium, which are beneficial to avoiding the failure of terminal equipment to occupy channels continuously and repeatedly.

In a first aspect, the present application provides a measurement method applied to a first access network device, where the method includes: receiving a measurement result of at least one first channel from a terminal device, wherein the measurement result comprises the load condition of the at least one first channel, and the first channel is an unlicensed spectrum channel; and determining a target channel from the at least one first channel based on the measurement result of the at least one first channel, wherein the target channel is used for data transmission between the terminal equipment and the first access network equipment or is used for random access of the terminal equipment to the target access network equipment.

Based on the method described in the first aspect, the first access network device can determine the load condition of the first channel at the terminal device side according to the measurement result of the first channel, so that an idle target channel can be selected for the terminal device to perform data transmission or random access, and the situation that the terminal device fails to occupy the channel continuously for multiple times is avoided, so that uplink data transmission is blocked or a cell cannot be accessed.

In one possible implementation, the method further includes: and sending first indication information to the terminal equipment, wherein the first indication information is used for indicating the terminal equipment to measure at least one first channel. Based on the implementation manner, the first access network device enables the terminal device to measure at least one first channel through the first indication information to obtain a corresponding measurement result, and determines the load condition of the first channel at the terminal device side, so that an idle target channel can be selected for data transmission or random access of the terminal device, and the situation that the terminal device fails to occupy channels continuously for many times is avoided, and uplink data transmission is blocked or a cell cannot be accessed.

In one possible implementation, the target channel is used for data transmission between the terminal device and the first access network device; before sending the first indication information to the terminal device, the method further comprises: measuring the load conditions of a plurality of second channels to obtain measurement results of the second channels, wherein the second channels are unlicensed spectrum channels; at least one first channel is determined from the plurality of second channels based on the measurement results of the plurality of second channels, the first channel having a lower load than other channels of the plurality of second channels than the first channel. Based on the implementation manner, the first access network device can determine a light-load channel from the plurality of second channels through the measurement results of the plurality of second channels as the first channel, and since the target channel is determined from at least one first channel in the subsequent determination of the target channel, the target channel is idle for the first access network device and idle for the terminal device, so that the situation that the first access network device judges that the channel can be used for transmitting downlink data due to inconsistent loads of the channel on two sides of the first access network device and the terminal device can be avoided, other devices possibly occupy the channel around the terminal device, the interference is larger, and the success rate of receiving the data by the terminal device is reduced.

In one possible implementation, the method further includes: receiving unlicensed spectrum channel occupancy information from at least one second access network device; determining a target channel from the at least one first channel based on the measurement result of the at least one first channel, wherein the specific implementation manner is as follows: a target channel is determined from the at least one first channel based on unlicensed channel occupancy information of the at least one second access network device and the measurement result of the at least one first channel. Based on this implementation, it is advantageous to enable the first access network device to select a more suitable target channel.

In a possible implementation manner, the target channel is used for random access of the terminal device to the target access network device, and before the first indication information is sent to the terminal device, the method further includes: receiving unlicensed spectrum channel occupancy information from at least one second access network device; receiving neighbor cell measurement information from terminal equipment, wherein the neighbor cell measurement information is used for indicating that the difference between the neighbor cell signal quality and the signal quality of the local cell is larger than a first threshold and/or the neighbor cell signal quality is larger than a second threshold; determining a target access network device from the at least one second access network device based on the neighbor cell measurement information; at least one first channel is determined based on the neighbor measurement information and unlicensed spectrum channel occupancy information of the target access network device. Based on the implementation manner, the first access network device can select a channel with idle channel through unlicensed spectrum channel occupation information of the target access network device as a first channel, and the target channel is idle for the target access network device and idle for the terminal device because the target channel is determined from at least one first channel when the target channel is determined later, so that random access failure caused by multiple LBT failures of the terminal device can be avoided, and the success rate of random access of the terminal device is improved.

In one possible implementation, the method further includes: and sending second indication information to the target access network equipment, wherein the second indication information indicates the target channel.

In one possible implementation, the second indication information further indicates a measurement result of at least one first channel. Based on the implementation manner, the target access network equipment is beneficial to knowing the channel state of the terminal equipment side.

In a second aspect, the present application provides a measurement method, applied to a terminal device, the method including: measuring the load condition of at least one first channel to obtain a measurement result of the at least one first channel, wherein the first channel is an unlicensed spectrum channel; and sending a measurement result of at least one first channel to the first access network device, wherein the measurement result of the at least one first channel is used for determining a target channel, and the target channel is used for data transmission between the terminal device and the first access network device or is used for random access of the terminal device to the target access network device.

The second aspect may refer to the above advantageous effects of the first aspect, and embodiments of the present application are not described herein.

Based on the implementation mode, the measurement time of the third channel is prolonged, so that the terminal equipment can obtain more accurate measurement results, besides, the measurement time of the idle channel can be reduced, and the energy loss of the terminal equipment is reduced.

All six terminal devices are capable of communicating with the access network device. Of course the number of terminal devices and access network devices in fig. 1 is only an example, and fewer or more may be used.

The access network device in the present application may be an evolved Node B (eNB or eNodeB) in LTE; or a base station in a 5G network, or other base stations evolving in the future, broadband network service gateways (broadband network gateway, BNG), converged switches or non-third generation partnership project (3rd generation partnership project,3GPP) access devices, etc., as embodiments of the present application are not specifically limited. By way of example, the base station in the embodiments of the present application may include various forms of base stations, for example: macro base stations, micro base stations (also referred to as small stations), relay stations, access points, next generation base stations (gndebs, gnbs), transmission and reception points (transmitting and receiving point, TRP), transmission points (transmitting point, TP), mobile switching centers, devices-to-devices (D2D), vehicle-to-devices (V2X), machine-to-machine (M2M) communication, devices that assume wireless access functions in internet of things (Internet of Things) communication, and the like, which are not particularly limited in this embodiment of the present application.

The terminal device may also be a satellite phone, a cellular phone, a smart phone, a wireless data card, a wireless modem, a machine type communication device, a terminal in a wireless device-to-device (D2D), a terminal in a car networking (vehicle to everything, V2X), a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in an industrial control (industrial control), a wireless terminal in an unmanned (self driving), a wireless terminal in a remote medical (remote media), a wireless terminal in a smart grid (smart carrier), a wireless terminal in a smart carrier (smart carrier), a wireless terminal in a future communication, a smart terminal in a smart carrier (smart carrier), or the like, which may be a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a personal digital processing (personal digital assistant, PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, an unmanned (unmanned) or a wireless device, a wireless terminal in a smart carrier (smart carrier), a smart terminal in a future communication, or the like.

In addition, in the embodiment of the present application, the terminal device may refer to a device for implementing a function of the terminal device, or may be a device capable of supporting the terminal device to implement the function, for example, a chip system, and the device may be installed in the terminal device. For example, the terminal device can also be a vehicle detector, a sensor in a gas station.

Fig. 2A illustrates a communication network architecture in the communication system provided herein, to which the embodiments provided later are applicable. The access network device 1 is a source access network device (or called a working access network device, or a service access network device) of the terminal device, and the access network device 2 is a target access network device (or called a standby access network device) of the terminal device, that is, an access network device that provides services for the terminal device after handover. "handover" means that the access network device serving the terminal device is handed over, and is not limited to "cell handover". The "handover" may refer to a handover due to a change in an access network device serving a terminal device. For example, when the source access network device of the terminal device fails, the standby access network device provides services for the terminal device. For another example, in the process that the terminal equipment is switched from the source access network equipment to communicate with another access network equipment, the switched target access network equipment provides service for the terminal equipment. The accessed cells before and after the terminal equipment is switched can be changed or not. It will be appreciated that the alternative access network device is a relative concept, e.g. with respect to one terminal device, the access network device 2 is an alternative access network device to the access network device 1 and with respect to another terminal device, the access network device 1 is an alternative access network device to the access network device 2.

The access network device 1 and the access network device 2 may be two different devices, e.g. the access network device 1 and the access network device 2 are two different access network devices. The access network device 1 and the access network device 2 may also be two sets of functional modules in the same device. The functional modules may be hardware modules, or software modules, or both. 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, the access network device 1 and the access network device 2 are not transparent to the terminal device. The terminal device can know which access network device is interacting with when interacting with the corresponding access network device. In another implementation, the access network device 1 and the access network device 2 are transparent to the terminal device. The terminal device is able to communicate with the access network devices but is not aware of which of the two access network devices is interacting with. Alternatively, only one access network device may be considered for the terminal device. In the following description, the access network device may be the access network device 1 or the access network device 2.

Fig. 2B illustrates another communication network architecture in the communication system provided herein. As shown in fig. 2B, the communication system includes a core network (new core) and a radio access network (radio access network, RAN). Wherein access network equipment (e.g., base stations) in the RAN includes baseband means and radio frequency means. The baseband device may be implemented by one or more nodes, and the radio frequency device may be implemented independently from the baseband device, may be integrated into the baseband device, or may be partially integrated into the baseband device. The access network device in the RAN may be an access network device having a Distributed Unit (DU) split architecture, where a plurality of DUs may be centrally controlled by one CU, and one DU may be connected to a plurality of CUs (not shown in the figure). The CU and the DU may be connected by an interface, for example, an F1 interface. CUs and DUs may be partitioned according to the protocol layers of the wireless network. One possible division is, for example: the CU is used to perform functions of a radio resource control (radio resource control, RRC) layer, a service data adaptation protocol (service data adaptation protocol, SDAP) layer, and a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, and the DU is used to perform functions of a radio link control (radio link control, RLC) layer, a medium access control (media access control, MAC) layer, a physical (physical) layer, and the like. It will be appreciated that the partitioning of CU and DU processing functions in accordance with such protocol layers is merely an example, and may be partitioned in other ways. For example, a CU or DU may be divided into functions with more protocol layers. For another example, a CU or DU may also be divided into partial processing functions with protocol layers. In one design, part of the functions of the RLC layer and the functions of the protocol layers above the RLC layer are set at CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set at DU. In another design, the functionality of a CU or DU may also be partitioned by traffic type or other system requirements. For example, according to the time delay division, the function of processing time which needs to meet the time delay requirement is set in the DU, and the function which does not need to meet the time delay requirement is set in the CU. In another design, a CU may also have one or more functions of the core network. One or more CUs may be centrally located, as well as separately located. For example, the CUs can be arranged on the network side to facilitate centralized management. The DU may have multiple radio functions, or the radio functions may be set remotely.

Fig. 2C illustrates another communication network architecture in the communication system provided herein. With respect to the architecture shown in fig. 2B, the Control Plane (CP) and the User Plane (UP) of the CU may also be implemented separately and separated into different entities, i.e., a control plane CU entity (CU-CP entity) and a user plane CU entity (CU-UP entity), respectively. In this network architecture, the signaling generated by the CU may be transmitted to the terminal device through a DU, or the signaling generated by the terminal device may be transmitted to the CU through a DU. The DU may be passed through to the terminal device or CU directly through protocol layer encapsulation without parsing the signaling. In this network architecture, the CU is divided into access network devices on the RAN side, and the CU may be divided into access network devices on the CN side, which is not limited in this application.

In the embodiment of the present application, the means for implementing the function of the access network device may be the access network device, or may be a means capable of supporting the access network device to implement the function, for example, a chip system or a combination device or a component capable of implementing the function of the access network device, where the apparatus may be installed in the access network device. In the technical solution provided in the embodiments of the present application, taking the device for implementing the function of the access network device as an example of the access network device, the technical solution provided in the embodiments of the present application is described.

For a better understanding of the embodiments of the present application, the following first describes related concepts related to the embodiments of the present application:

1. unlicensed spectrum

Unlicensed spectrum (also referred to as unlicensed spectrum) may be understood as a physical frequency band that is open to an indefinite number of individual users that can be used directly without registration or individual permission. The unlicensed spectrum belongs to a radio spectrum resource, and the radio spectrum resource further comprises a licensed spectrum, wherein the licensed spectrum is a physical frequency band which can be used only by obtaining special use rights, license or permission. The radio spectrum resource used by the terminal device is typically licensed spectrum. But with the increasing proliferation of access network devices, limited spectrum resources are difficult to meet the huge data service requirements. To address this problem, long term evolution (Long Term Evolution, LTE) and New air interface (NR) have proposed a Licensed-Assisted Access (LAA) system for use in unlicensed bands and a New air interface (New Radio Unlicensed, NR-U) system for operation in unlicensed bands, respectively. The access of the unlicensed spectrum channel needs to meet the regulatory rule, that is, the channel can be accessed only after Listen-Before-Talk (LBT), and the nature of the LBT mechanism is a channel access rule. The terminal device needs to monitor whether the channel is idle or not before accessing the channel and starting to transmit data, and can occupy the channel if the channel has remained idle for a period of time.

Based on the above description of unlicensed spectrum, before uplink transmission of the terminal device, specific uplink resource information needs to be issued by the access network device, where the uplink resource information includes an uplink channel and a transmission time for transmission. Before uplink transmission, the terminal device will perform LBT on the designated uplink channel, and after the LBT detection result is idle, the terminal device may occupy the channel to perform uplink transmission. If the terminal device performs handover between cells and needs to perform random access channel (Random Access Channel, RACH) access in the target cell, the target access network device of the target cell sends RACH resource information to the terminal device through the source access network device, and when the LBT detection result of the terminal device on one RACH channel is idle, the terminal device can send RACH related information on the RACH channel.

Since the terminal device and the access network device are not located in the same location in practice, for example, the access network device may be located outdoors and the terminal device may be located indoors. The terminal device is easily affected by Wireless-Fidelity (Wi-Fi), bluetooth and the like on the unlicensed spectrum channel indoors, so that the access network device and the terminal device have different LBT or load judgment results on the same unlicensed spectrum channel. Therefore, an unlicensed spectrum channel which is preferable by the access network device for guaranteeing uplink transmission and is considered to be light in load by the access network device may be a heavy-load channel for the terminal device, so that the terminal device may have the problems that the LBT frequently fails and cannot occupy the channel, the uplink data transmission is blocked, or the terminal device cannot access a cell, and the like.

In order to avoid the failure of the terminal device to occupy the channel multiple times continuously, a measurement method is proposed in the present application, please refer to fig. 3. As shown in fig. 3, the measurement method includes the following steps 301 to 303. The method execution body shown in fig. 3 may be the terminal device and the first access network device, or the execution body may be a chip in the terminal device or a chip of the first access network device. Fig. 3 illustrates an execution body of a method by using a terminal device and a first access network device as an example, and the execution body of a measurement method is not limited in the embodiment of the present application. Wherein:

301. the terminal equipment measures the load condition of at least one first channel to obtain a measurement result of the at least one first channel, wherein the first channel is an unlicensed spectrum channel.

In this embodiment of the present application, the first channel is an unlicensed spectrum channel, and if the terminal device needs to occupy the first channel, LBT needs to be performed first, and the first channel can be occupied after the LBT is successful. The terminal device measuring the load situation of at least one first channel means that the terminal device measures the energy of the first channel for a certain time. If the energy of the first channel is always greater than the preset threshold value in the measured time, the first channel is heavily loaded, and other devices may occupy the first channel. If the energy of the first channel is always smaller than the preset threshold value in the measured time, the first channel is lighter in load and is in an idle state. The measurement manner of the first channel by the terminal device includes, but is not limited to, radio resource management (Radio Resource Management, RRM) measurement, minimization of drive test (Minimization ofdrive tests, MDT) measurement, and the like, which are not limited in this embodiment.

The measurement mode of the terminal device on the first channel can be periodic measurement or continuous measurement. Periodic measurements refer to measurements taken every one period, e.g. the terminal device takes measurements of the first channel every 5 seconds, for a period of 100 ms, which lasts for 5 minutes. Continuous measurement refers to measurements performed without interruption, e.g. the terminal device is measuring the first channel for 5 minutes at all times.

Alternatively, the terminal device may employ a specific measurement mode for a part of the channels in 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 prolonged, and a measurement result of the third channel is obtained, wherein the third channel is one channel of the 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. The terminal device may extend the measurement time of the third channel, which may refer to extending the time for performing continuous measurement on the third channel, for example, the channels other than the third channel only need to be continuously measured for 5 minutes, and the third channel needs to be continuously measured for 6 minutes; alternatively, it may also refer to performing shorter periodic measurements on the third channel, for example, the terminal device performs measurements on channels other than the third channel once every 5 seconds, and performs measurements on the third channel once every 2 seconds. Based on the implementation mode, the measurement time of the third channel is prolonged, so that the terminal equipment can obtain more accurate measurement results for the channels with heavier loads, and besides, the measurement time of the channels with lighter loads can be reduced, and the energy loss of the terminal equipment is reduced.

In this embodiment of the present application, the measurement result of the at least one first channel is used to determine a target channel, where the target channel is used for data transmission between the terminal device and the first access network device, or the target channel is used for random access of the terminal device to the target access network device. The first access network device refers to access network device connected with the terminal device, and the target access network device refers to access network device corresponding to the switched target cell when the terminal device triggers cell switching. The target channel may be determined by the first access network device, the terminal device sending the measurement of the at least one channel to the first access network device, the target channel being determined by the first access network device based on the measurement. Or if the target channel is used for the terminal equipment to randomly access the target access network equipment, the target channel can be determined by the target access network equipment, the terminal equipment sends the measurement result of the at least one channel to the first access network equipment, the first access network equipment forwards the measurement result to the target access network equipment, and the target access network equipment determines the target channel based on the measurement result. The embodiments of the present application are not limited to devices that determine a target channel. Based on the method, before data transmission or random access is performed, the terminal device performs measurement on at least one first channel in advance to obtain a measurement result, the measurement result of the first channel is used for determining a target channel with idle channel, and the target channel is used for data transmission or random access of the terminal device, so that the situation that the terminal device fails to occupy the channel continuously for many times, and uplink data transmission is blocked or the terminal device cannot access a cell is avoided.

The measurement result measurement of the first channel may include one or more of the following information: average energy detection result of the first channel, time ratio of the energy of the first channel higher than a preset threshold, other system types using the first channel, and the like. The time duty ratio of the energy of the first channel above the preset threshold refers to the ratio between the time the energy of the first channel is above the preset threshold and the total time the first channel is measured. The larger the time duty ratio that the energy of the first channel is higher than the preset threshold value is, the heavier the load of the first channel is, and other devices occupy the channel; the smaller the time duty cycle of the energy of the first channel above the preset threshold, the lighter the load of the first channel, indicating that 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 this embodiment of the present application. Other system types using the channel refer to the system type of the device occupying the first channel when the first channel is occupied by other devices, such as Wi-Fi, bluetooth, etc. The measurement result of the first channel may include other information besides the above-described 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 the terminal device receives the first indication information from the first access network device. The first indication information is used for indicating the terminal equipment to measure at least one first channel. After the terminal device receives the first indication information, measurement can be performed 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, and the like. Based on the implementation manner, the first access network device enables the terminal device to measure at least one first channel through the first indication information to obtain a corresponding measurement result, and determines the load condition of the first channel at the terminal device side, so that an idle target channel can be selected for data transmission or random access of the terminal device, and the situation that the terminal device fails to occupy channels continuously for many times is avoided, and uplink data transmission is blocked or a cell cannot be accessed.

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 a target channel from the at least one first channel based on the measurement of the at least one first channel.

In the 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 is used for random access of the terminal device to the target access network device. The first access network device can determine the load condition of the first channel at the terminal device side according to the measurement result of the first channel, so that an idle target channel can be selected for data transmission or random access of the terminal device, and the situation that the terminal device fails to occupy the channel continuously for many times, which results in blocked uplink data transmission or incapability of accessing cells, is avoided.

Based on the two purposes of the target channel described above, the embodiments of the present application include the following two cases:

case one: the terminal device needs to perform data transmission with the first access network device. In this case, the target channel is used for data transmission between the terminal device and the first access network device.

In one possible implementation manner, before the first access network device sends the first indication information to the terminal device, the method further includes: the first access network equipment measures the load conditions of a plurality of second channels to obtain measurement results of the second channels, wherein the second channels are unlicensed spectrum channels; the first access network device determines at least one first channel from the plurality of second channels based on the measurement results of the plurality of second channels, the first channel having a load lower than that of other channels than the first channel of the plurality of second channels. The plurality of second channels may refer to all unlicensed spectrum channels on the first access network device side, or may refer to a part of unlicensed spectrum channels on the first access network device side, which is not limited in the embodiment of the present application. Based on the implementation manner, the first access network device can determine a light-load channel from the plurality of second channels through the measurement results of the plurality of second channels as the first channel, and since the target channel is determined from at least one first channel in the subsequent determination of the target channel, the target channel is idle for the first access network device and idle for the terminal device, so that the situation that the first access network device judges that the channel can be used for transmitting downlink data due to inconsistent loads of the channel on two sides of the first access network device and the terminal device can be avoided, other devices possibly occupy the channel around the terminal device, the interference is larger, and the success rate of receiving the data by the terminal device is reduced.

Alternatively, the measurement result of the second channel may include an average energy detection result of the second channel and/or a time duty cycle in which the energy of the second channel is higher than a preset threshold. The time duty cycle of the energy of the second channel being above the preset threshold refers to the ratio between the time the energy of the first channel is above the preset threshold and the total time the first channel is measured. The larger the time duty ratio of the energy of the second channel is higher than the preset threshold value, the heavier the load of the second channel is, other devices occupy the channel, and the smaller the time duty ratio of the energy of the second channel is higher than the preset threshold value, the lighter the load of the second channel is, and the channel is idle. The measurement result of the second channel may also include other information, which is not limited in the embodiment of the present application.

Alternatively, the manner in which the first access network device measures the second channel may be a periodic measurement, e.g. the second channel is measured every 5 seconds. Alternatively, the manner in which the first access network device measures the second channel may be a persistence measurement, e.g., a persistence measurement of the second channel for 2 minutes. Further optionally, the first access network device may further receive unlicensed spectrum channel occupation information from at least one second access network device, where the unlicensed spectrum channel occupation information indicates occupation of second channels by the second access network device, determine a second channel used by a non-neighboring cell from a plurality of second channels based on the unlicensed spectrum channel occupation information, and preferentially measure the second channel used by the non-neighboring cell.

Wherein the unlicensed spectrum channel occupancy information may include one or more of the following: unlicensed channel IDs and frequency points used up and down by the second access network device; information such as an LBT success rate, an energy measurement threshold, an energy measurement result (i.e. measured average energy) of the second access network device on the unlicensed channel, wherein the energy measurement result may be an LBT detection result based on the second access network device or a terminal device connected to the second access network device; the second access network device will send the data volume on a specific unlicensed channel, e.g. 100M data on channel 1.

Optionally, the specific implementation manner of the first access network device to determine at least one first channel from the plurality of second channels based on the measurement results of the plurality of second channels may be: the first access network is configured to determine at least one first channel based on the traffic type of the terminal device and/or the location of the terminal device, the measurement results of the plurality of second channels and unlicensed spectrum channel occupancy information from the plurality of second access network devices. For example, if the service timeliness requirement and the rate requirement of the terminal device are high, the first access network device preferentially selects a first channel which is not occupied by a neighboring cell and has a lighter load from a plurality of second channels. Also exemplary, if the terminal device is located at the zone edge, the first access network device selects a first channel occupied by a non-neighboring zone.

Optionally, the method further comprises: the first access network device receives unlicensed spectrum channel occupation information from at least one second access network device, and the specific implementation manner of determining a target channel from at least one first channel based on the measurement result of the at least one first channel by the first access network device is as follows: the first access network device determines a target channel from the at least one first channel based on unlicensed channel occupancy information of the at least one second access network device and the measurement result of the at least one first channel. The first access network device determines a target channel from at least one first channel according to the service type of the terminal device, the measurement result of the at least one first channel and unlicensed spectrum channel occupation information from a plurality of second access network devices, and the first access network device prefers that a neighbor does not occupy and the terminal device measures the target channel with lighter load for the service with high real-time requirements and high speed requirements.

In one possible implementation manner, the first access network device may integrate the measurement result of at least one first channel and the measurement result of a plurality of second channels to obtain channel information, and send the channel information to at least one second access network device, so that the second access network device is beneficial to be able to know the channel state 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 a load condition of a specific one or more channels in the cell, for example, an average energy detection result of a cell edge and a cell center, an average occupied duration of the channels, and further divide the load condition to distinguish the detection results of the terminal device or the access network device. The specific channel may be a channel used by both the cell and the neighboring cell, or may be a channel which is not used by the cell but is not used by the neighboring cell, or may be a channel which is not used by the cell but is used by the neighboring cell, which is not limited.

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, the measurement result needs to be sent to the affiliated CU, and then the affiliated CU performs subsequent target channel confirmation. If the first access network device is a split architecture of the CU-CP and the CU-UP, after the CU-CP determines a target channel based on a measurement result of the first channel and unlicensed spectrum occupation channel information of the second access network device, the CU-UP specifically generates an uplink scheduling Grant (Grant) and sends the Grant to the terminal device. If the first access network device is a split architecture of CU-CP1 and CU-CP2, the second channel may be measured by CP1 and the target channel may be determined, and the first indication information indicating that the terminal device measures the first channel may be generated by CP 2.

And a second case: the terminal device needs to switch to the target access network device. In this case, the target channel is used for random access of the terminal device to the target access network device.

In one possible implementation manner, before the first access network device sends the first indication information to the terminal device, the method further includes: the first access network equipment receives unlicensed spectrum channel occupation information from at least one second access network equipment; the first access network equipment receives neighbor cell measurement information from the terminal equipment, wherein the neighbor cell measurement information is used for indicating that the difference between the neighbor cell signal quality and the signal quality of the local cell is larger than a first threshold and/or the neighbor cell signal quality is larger than a second threshold; the first access network equipment determines target access network equipment from at least one second access network equipment based on neighbor cell measurement information; the first access network device determines at least one first channel based on the neighbor measurement information and unlicensed spectrum channel occupancy information of the target access network device.

The neighbor cell measurement information comprises a measurement result of signal quality of the neighbor cell by the terminal equipment. The first access network equipment determines target access network equipment from at least one second access network equipment based on neighbor cell measurement information, namely the first access network equipment determines a cell with the best signal quality, namely a cell closest to the terminal equipment, according to the neighbor cell measurement information, and the access network equipment corresponding to the cell is the target access network equipment. The method comprises the steps that neighbor cell measurement information of first access network equipment and unlicensed spectrum channel occupation information of target access network equipment determine at least one first channel, and the first channel is an idle channel at the side of the target access network equipment. Based on the implementation manner, the first access network device can select a channel with idle channel through unlicensed spectrum channel occupation information of the target access network device as a first channel, and the target channel is idle for the target access network device and idle for the terminal device because the target channel is determined from at least one first channel when the target channel is determined later, so that random access failure caused by multiple LBT failures of the terminal device can be avoided, and the success rate of random access of the terminal device is improved.

Optionally, the method further comprises: the first access network device sends second indication information to the target access network device, the second indication information indicating the target channel. Wherein the second indication information may be carried in a Handover Request (Handover Request) message. Alternatively, the second indication information may be carried in another message, or the second indication information may be carried in a new message, which is not limited in the embodiment of the present application. Correspondingly, after the target access network equipment receives the second indication information sent by the first access network equipment, the target access network equipment determines a target channel indicated in the second indication information as a channel for random access of the terminal equipment, and sends terminal equipment response information through the first access network equipment, wherein the response information carries a channel identification ID of the target channel and corresponding frequency point and bandwidth information. Wherein the response information may be carried in a handover request response (Handover Request ACK) message to the first access network device, which sends the response information to the terminal device by configuring the handover information. The response information may 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 further indicates a measurement result of the 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 to select the target channel or not select the target channel by responding to the information. If the target access network device does not select the target channel, it may 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 random access by the terminal device, and indicate the channel through the response information. Based on the implementation manner, the target access network equipment is beneficial to knowing the channel state of the terminal equipment 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, the measurement result needs to be sent to the CU, and then the CU performs subsequent target channel confirmation and interaction with the second access network device. If the first access network device is a split architecture of the CU-CP and the CU-UP, the CU-CP needs to determine a first channel to be measured based on an unlicensed spectrum of the second access network device, and then the CU-UP completes confirmation of a target channel based on measurement information of at least one first channel of the terminal device. If the first access network device is a split architecture of CU-CP1 and CU-CP2, the target channel may be determined by CP1, and the first indication information indicating that the terminal device measures the first channel may be generated by CP 2.

In one 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, and the first access network device may forward the measurement result of the at least one first channel to the target access network device after receiving the measurement result of the at least one first channel from the terminal device, and the target access network device determines the target channel for the terminal device to perform random access based on the measurement result of the at least one first channel. Based on the implementation manner, the target channel determined by the target access network equipment is in an idle state for both the terminal equipment and the target access network equipment.
