Description

Communication method, device, terminal and network equipment

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application No. 202310999771.5 filed in China on August 9, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the field of wireless technology, and in particular to a communication method, apparatus, terminal, and network equipment. Background Art

[0004] Usually, the terminal (User Equipment) triggers measurement reporting and cell switching operations by the change in the signal condition of the Reference Signal Receiving Power (RSRP) / Reference Signal Received Quality (RSRQ) corresponding to the Physical Cell Identities (PCI), or by sensing the beam under the PCI, that is, the Channel State Information Reference Signal (CSI-RS) or the Synchronization Signal Block (SSB) corresponding to the RSRP / RSRQ signal condition.

[0005] However, for non-terrestrial network (NTN) systems, such as satellite network systems, there are cases where the cell coverage is large (up to more than 1,000 kilometers) and the coverage spans multiple regions and multiple countries. The beams covered by a satellite are the same, and the physical cell identifiers (PCIs) used are the same. Based on this scenario, due to being in different regions or countries within the same beam range, changes in the RSRP / RSRQ signal conditions corresponding to the usual PCI are used, or changes in the RSRP / RSRQ signal conditions corresponding to the beam CSI-RS or SSB under the PCI are sensed to trigger measurement reports and cell switching. The terminal cannot clearly distinguish the boundaries of wireless coverage, and therefore cannot perform cell switching between multiple regions and multiple areas, resulting in connection rejection.

[0006] On the other hand, for special user equipment (UE) such as drones, the different channel models and propagation characteristics caused by their flight characteristics (such as different flight speeds and altitudes) can cause severe uplink interference to ground UEs. The physical cell model of related technologies and the resource sharing model of all UEs in the cell can also cause strong downlink interference to the drones themselves. At the same time, a large number of cell change processes such as handovers and reestablishments generate a large amount of service interruption and signaling overhead, which is not conducive to improving the service performance of drones. In particular, the different channel models and propagation characteristics caused by their flight characteristics (different flight speeds and altitudes) and the continuous replacement of planar cells, especially for fast-moving drones, or drones during takeoff and landing, lead to excessive complexity in the management of drone handovers, access, and neighbor relationships.

[0007] Summary of the Invention

[0113] In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0114] In order to solve the problem that in the scenario where the satellite changes but the physical cell ID remains unchanged within the network coverage of the NTN, the terminal in the related technology cannot recognize the satellite change because the physical cell ID remains unchanged, resulting in the terminal being unable to perform different measurements of the same cell ID of different satellites and / or unable to perform timely re-uplink and downlink synchronization, resulting in connection rejection, the embodiment of the present disclosure provides a communication method for obtaining first information and / or a first signal sent by a network device; the first information and / or the first signal are used to determine the service area and / or coverage area provided by the first target object, and / or are used to indicate the relevant operations to be performed, so that the terminal can perform relevant operations according to the first information and / or the first signal to avoid performing cell switching between different regions or areas, and the occurrence of connection rejection.

[0115] One embodiment of the present disclosure provides a communication method, which is executed by a terminal, as shown in FIG1 , and includes:

[0116] S110: Acquire first information and / or a first signal sent by a network device; the first information and / or the first signal are used to determine a service area and / or coverage area provided by a first target object, and / or the first information is used to instruct a related operation to be performed; wherein the first target object includes one or more of at least one beam, at least one cell, and at least one satellite;

[0117] S120, perform relevant operations according to the first information and / or the first signal; wherein the relevant operations include one or more of satellite switching, cell switching, roaming request, beam switching, cell access and uplink / downlink synchronization.

[0118] Optionally, the first signal includes one or more of a primary synchronization signal, a secondary synchronization signal and a synchronization signal block SSB.

[0119] In the communication method described in the embodiments of the present disclosure, optionally, the network device in the non-terrestrial network (NTN) may be a satellite base station, wherein beams and / or cells within the network coverage area transmitted by a satellite base station all use the same physical cell identifier (PCI).

[0120] In one embodiment, the first information includes second information for indicating area information of the service area and / or coverage area. The terminal can determine whether the area indicated by the first information belongs to a restricted access area of ​​the terminal based on the area information in the second information, so as to further determine whether it is necessary to perform one or more of satellite switching, cell switching, roaming request, beam switching and uplink / downlink synchronization to avoid connection rejection.

[0121] Optionally, the second information includes one or more of a physical cell identifier PCI, a synchronization signal block SSB, system message information, a virtual cell identifier and a cell global identifier.

[0122] In another embodiment, the service area and / or coverage area provided by the first target object can be determined through a first signal. The first signal includes one or more of a primary synchronization signal, a secondary synchronization signal and a synchronization signal block SSB. The terminal can determine whether the area indicated by the first signal belongs to a restricted access area of ​​the terminal to further determine whether it is necessary to execute one or more of satellite switching, cell switching, roaming request, beam switching and uplink / downlink synchronization to avoid connection rejection.

[0123] In another embodiment, optionally, the first information includes one or more of the following:

[0124] Second information, used to indicate area information of a service area and / or coverage area provided by the first target object;

[0125] The third information is used to indicate change information of the satellite providing coverage and / or service for the terminal;

[0126] Fourth information, used to indicate satellite information that provides coverage and / or service to the terminal after satellite switching;

[0127] The fifth information is used to indicate the relevant operation performed by the terminal;

[0128] Sixth information, used to indicate configuration information when the first target object provides services and / or coverage;

[0129] The seventh information is used to indicate measurement configuration information of the terminal measuring the first target object.

[0130] According to the second to seventh information mentioned above, the terminal is able to perform differentiated measurements on different beams / cells / satellites providing services, even though they send the same PCI and / or the same SSB sequence, so as to avoid errors in the evaluation of the measurement signals, thereby avoiding cell switching between different regions or areas, and the occurrence of connection rejection.

[0131] Specifically, according to the change information of the satellite providing coverage and / or service to the terminal indicated by the third information, and / or, the satellite information providing coverage and / or service to the terminal after the satellite switching is indicated by the fourth information, and / or, the relevant operations performed by the terminal are indicated by the fifth information, so that the terminal can correctly execute one of satellite switching, cell switching, roaming request, beam switching and uplink / downlink synchronization; according to the configuration information when the first target object provides service and / or coverage indicated by the sixth information, the terminal can perform differentiated measurements on different beams / cells / satellites providing services even though they send the same PCI / the same SSB sequence, so as to avoid errors in the evaluation of the measurement signal.

[0132] Using the communication method described in the embodiment of the present invention, the cell / beam coverage of the satellite base station is large, and the coverage range exists across regions and / or countries. The terminal cannot clearly define the coverage boundary of the beam and / or cell received by the network device, and the area where the beam and / or cell exists belongs to the restricted access area of ​​the terminal, resulting in the connection being rejected. In the embodiment of the present invention, the first information sent by the network device indicates the service area and / or coverage area of ​​at least one beam, at least one cell and at least one satellite, so that the terminal can determine whether the service area and / or coverage area of ​​at least one beam, at least one cell and at least one satellite belongs to the restricted access area of ​​the terminal based on the first information.

[0133] In another implementation scenario, in one area, during the process of satellite change, the rapid movement of the satellite may cause a satellite to be changed in a few seconds or minutes in an area, resulting in frequent layer 3 switching of stationary terminals. Therefore, when adopting the technology of satellite change but physical cell ID does not change, in the scenario where the satellite changes but the physical cell ID does not change, the terminal cannot identify the satellite change because the physical cell ID does not change, resulting in the terminal being unable to perform different measurements of the same cell ID of different satellites or / and unable to perform timely re-uplink and downlink synchronization, thereby causing service interruption. To address this problem, in an embodiment of the present disclosure, the network device sends first information to the terminal for indicating relevant information of the service area and / or coverage area provided by the first target object, so that the terminal can determine the change information of the satellite and / or the information of the new satellite in the service area and / or coverage area provided by the first target object based on the first information, thereby performing at least one of satellite switching, cell switching, roaming request and beam switching.

[0134] In the embodiments of the present disclosure, it should be noted that the service area and / or coverage area referred to herein may be a range defined by regional or national boundaries; and / or the service area and / or coverage area referred to herein may be the range covered by a satellite within a certain period of time. Alternatively, the area covered by a satellite within a certain period of time may be covered by another satellite within a different period of time; and the coverage areas of the two satellites may or may not overlap.

[0135] In one implementation of the communication method described in the embodiments of the present disclosure, the network device sends the same first signal (including at least one of signaling, signal or data) corresponding to at least one beam, at least one cell and / or at least one satellite.

[0136] Optionally, the first signal satisfies one or more of the following:

[0137] The first signals corresponding to different acquired beams are the same;

[0138] The first signals corresponding to different areas of the at least one cell are the same;

[0139] The first signals corresponding to the service ranges and / or coverage ranges provided by different satellites are the same.

[0140] In an embodiment of the present disclosure, the area information indicating the service area and / or coverage area provided by at least one beam, at least one cell and / or at least one satellite sent by the network device is indicated (or reflected) by the resource location sent by the first signal, and the first signal is transmitted at different resource locations corresponding to different areas of the service area and / or coverage area provided by at least one beam, at least one cell and / or at least one satellite.

[0141] It should be noted that, in an embodiment of the present disclosure, optionally, the resource location sent by the first signal indicates the service area and / or coverage area provided by the first target object, and then it can be determined that in an embodiment of the present disclosure, the first information is used to determine the scheme for determining the service area and / or coverage area provided by the first target object.

[0142] Optionally, the network device may obtain regional information of different areas of the application layer by interacting with core network elements, and send the first signal at different resource locations corresponding to different areas.

[0143] In this embodiment, although the first signal sent by the network device is the same for different regions, the terminal can correspond to different regions based on the different physical resources used by the network device to send the first signal. In this embodiment, different service areas and / or coverage areas are indicated based on the different resource locations used to send the first signal corresponding to at least one beam, at least one cell, and at least one satellite.

[0144] Optionally, the resource location includes but is not limited to only a physical resource block (PRB) location.

[0145] In another embodiment, the first information corresponding to the service / coverage area provided by at least one beam and / or cell, and / or at least one satellite includes configuration information (sixth information) for indicating when different beams / different cells / different satellites provide services / coverage, and the configuration information includes corresponding relationship information, wherein the corresponding relationship information indicates the relationship between the resource location used by the network device to send the first signal and the corresponding beam, cell, cell area, satellite, and at least one of the services / coverage provided.

[0146] For example, the indication information in the first beam and / or the first cell used to indicate the first beam and / or the first cell is the index of the SSB; for example, there are 64 SSBs under one PCI, and the first beam and / or the first cell sends SSBs with indices of 1-32 at t1, t3, t5, t7, ..., tm (m is an odd number), and sends SSBs with indices of 33-64 at t2, t4, t6, t8, ..., tn (n is an even number); the terminal distinguishes different beams / cells / satellites providing services that send the same PCI / the same SSB sequence based on the area information / indication identifier of the beam / cell, thereby performing corresponding measurement and / or switching operations.

[0147] Alternatively, the terminal may determine, based on the area information / indicator identifier of the beam / cell, that the measurement results of the SSBs of different satellites providing services will not be combined.

[0148] Optionally, the method further includes:

[0149] The correspondence information is obtained through a system message (such as a SIB message) and / or dedicated signaling.

[0150] The configuration information includes one or more of the following:

[0151] One or more of the time information, frequency domain position information, SSB index information, and CSI-RS resource information of the SSB sent by the first target object;

[0152] One or more of the time difference, frequency deviation and phase difference between at least one satellite transmitting an SSB and reaching the terminal or a reference position;

[0153] Time information of when the first target object provides and / or stops service;

[0154] The time information of the SSB includes one or more of a period, a start value and a duration.

[0155] It should be noted that, based on the above configuration information, the corresponding relationship information can be determined, that is, the following corresponding relationship can be determined:

[0156] A correspondence between different first target objects and one or more of the time information, frequency domain position information, SSB index information, and CSI-RS resource information of the SSB sent by the first target object;

[0157] The correspondence between one or more of the time difference, frequency offset and phase difference between different satellites and the satellite sending SSB to the terminal or a reference position;

[0158] The different first target objects and the time information of providing and / or stopping service of the first target object.

[0159] Specifically, the configuration information includes one or more of the following:

[0160] At least one of time information, frequency domain location information, SSB index information, and CSI-RS resource information of the SSB transmitted by the first beam and / or the first cell;

[0161] At least one of the time information, frequency domain location information, SSB index information, and CSI-RS resource information of the qth beam and / or the qth cell transmitting the SSB; (q is a natural number greater than 1);

[0162] At least one of a time difference, a frequency offset, and a phase difference between the first satellite transmitting the SSB and the second satellite transmitting the SSB and arriving at the terminal or a reference position;

[0163] At least one of the time information, frequency domain location information, SSB index information, and CSI-RS resource information of the qth beam and / or the qth cell transmitting the SSB; (q is a natural number greater than 1);

[0164] At least one of the following: time information, frequency domain position information, SSB index information, and CSI-RS resource information of the SSB transmitted by the first satellite;

[0165] At least one of the time information, frequency domain position information, SSB index information, and CSI-RS resource information transmitted by the qth satellite (q is a natural number greater than 1);

[0166] Time information of when the first beam and / or the first cell and / or the first satellite provides and / or stops service;

[0167] Time information of when the qth beam and / or the qth cell and / or the qth satellite provides and / or stops service.

[0168] According to the correspondence information and the resource location of sending the first signal, the service area and / or coverage area indicated by at least one beam, at least one cell and at least one satellite can be determined.

[0169] Therefore, in this embodiment, the correspondence information may correspond to the first information in the present disclosure, and the service area and / or coverage area provided by the first target object may be determined based on the combination of the first information and the first signal.

[0170] Specifically, the network device sends a first signal at a resource location corresponding to the area, and the terminal can determine the service area and / or coverage area provided by at least one beam, at least one cell and at least one satellite based on the correspondence information between the received different areas and the resource locations of the corresponding first signal transmissions, and based on the obtained resource locations of the first signal.

[0171] Specifically, the terminal determines the service area and / or coverage area provided by at least one beam, at least one cell and at least one satellite based on the corresponding relationship information and the resource location, and distinguishes different beams / cells / satellites providing services that send the same PCI / the same SSB sequence, thereby performing corresponding measurement and / or switching operations. For example, differentiated measurements are performed at the corresponding resource locations, and the measurement results of the SSBs of different satellites providing services will not be merged to avoid errors in the evaluation of the measurement signals.

[0172] Alternatively, the terminal determines the service area and / or coverage area provided by at least one beam, at least one cell, and at least one satellite based on the correspondence information and the resource location, and distinguishes between different beams / cells / satellites providing services even though they send the same PCI / the same SSB sequence, thereby performing correct satellite switching, cell switching, roaming request, and beam switching.

[0173] Alternatively, the terminal determines whether it is necessary to merge the measurement results of the SSB sent by the first satellite and the second satellite based on at least one of the time difference, frequency offset and phase difference between the SSB sent by the first satellite and the SSB sent by the second satellite arriving at the terminal or a reference position.

[0174] Specifically, if at least one of the time difference, frequency offset, and phase difference between the arrival of an SSB signal from a first satellite and an SSB signal from a second satellite at a terminal or a reference location exceeds a certain threshold, the combined result is poor, affecting the terminal's handover decision. Alternatively, if at least one of the time difference, frequency offset, and phase difference between the arrival of an SSB signal from a first satellite and an SSB signal from a second satellite at a terminal or a reference location exceeds a certain threshold, the terminal performs interference processing, puncturing, or signal filtering on the signal sent by the other satellite. If at least one of the time difference, frequency offset, and phase difference between the arrival of an SSB signal from a first satellite and an SSB signal from a second satellite at a terminal or a reference location does not exceed a certain threshold, the combined result is effective. Optionally, the terminal can utilize SFN technology for combined reception.

[0175] In one embodiment of the present disclosure, optionally, the method further includes:

[0176] Distinguishing different first target objects that send the same PCI and / or the same SSB sequence according to the corresponding relationship information;

[0177] According to the different first target objects that are distinguished, corresponding measurement and / or switching operations are performed.

[0178] Specifically, the configuration information sent by the service cell to indicate that the first target object provides service and / or coverage includes correspondence information. Through this correspondence information, different beams / cells / satellites providing services that send the same PCI / the same SSB sequence are distinguished, thereby performing corresponding measurement and / or switching operations.

[0179] Optionally, the way in which the service cell sends configuration information includes one or more of the following: Method 1, the service cell faces one carrier / frequency band, and configures multiple different measurement configuration information (seventh information) for the terminal for areas where different beams / different cells / different satellites provide services; in this way, the terminal can perform differentiated measurements at corresponding resource locations based on different measurement configuration information, thereby ensuring the correctness of the measurement results.

[0180] Among them, the measurement configuration information includes SMTC configuration information and / or measurement interval configuration information (which can also be described as measurement gap, or as gap pattern); specifically, the synchronization signal / physical broadcast channel block measurement timing configuration (SS / PBCH block measurement timing configuration, SMTC) is used to indicate the SSB measurement configuration of the terminal, including period, duration and offset, etc., and is mainly used for co-frequency measurement. The length of the measurement gap (Measurement gap) is the SSB transmission time + the radio frequency (Radio Frequency, RF) frequency modulation time. The new radio (New Radio, NR) measurement interval is divided into per UE (terminal-based) and per FR (FR-based). Per UE configuration means that the measurement of all frequency points to be measured is performed based on a set of measurement interval configurations. Per FR configuration means that the terminal can be configured with two measurement intervals at the same time, used for FR1 and FR2 respectively, and whether the per FR interval is supported is reported in the terminal capability.

[0181] In the present disclosure, the areas served by different satellites may be the same in geographical location, or may be different or overlapping.

[0182] For example, a serving cell is oriented towards one carrier / frequency band, and different configuration information is configured for the terminal in areas served by different satellites:

[0183] Measurement of the area served by the first satellite: corresponding to the first measurement configuration;

[0184] Measurement of the area served by the second satellite: corresponding to the second measurement configuration;

[0185] The measurement offsets of the first measurement configuration and the second measurement configuration are different, corresponding to t0 and t1 respectively;

[0186] Then, the terminal can perform differentiated measurements at corresponding resource locations t0 and t1 according to different measurement offsets in different configuration information, thereby ensuring the correctness of the measurement results.

[0187] In the second method, the serving cell configures multiple different measurement configuration information for the terminal for one carrier / frequency band;

[0188] The terminal then calculates the delay difference between the next arriving satellite and the current serving satellite based on its own location and satellite ephemeris information. Based on this calculated delay difference, the terminal can determine the specific beam / cell / satellite service area corresponding to the measured results under different configurations. Optionally, the terminal reports the correspondence between the final selected configuration and the beam / cell / satellite service area to the serving cell to ensure synchronization of measurement results between the network and the terminal.

[0189] For example, a serving cell is oriented to an area provided with services by one carrier / frequency band and different satellites, and a plurality of different measurement configuration information is configured for the terminal, namely, a first measurement configuration and a second measurement configuration, wherein the measurement offsets of the first measurement configuration and the second measurement configuration are different, corresponding to t0 and t1 respectively;

[0190] The terminal uses t0 to measure the current serving satellite (the first satellite). The terminal then calculates the time delay difference between the next arriving second satellite and the current serving satellite (the first satellite) based on its own position information and the ephemeris information of the first and second satellites. The terminal then determines the SSB measurement reception time window for the second satellite corresponding to the second measurement configuration corresponding to the offset t1. Optionally, the terminal reports the correspondence between the final selected measurement configuration information and the beam / cell / satellite service area to the serving cell to ensure synchronization of measurement results between the network and the terminal.

[0191] In this way, by adopting this implementation, the terminal can perform differentiated measurements at corresponding resource locations according to different measurement offsets in different measurement configuration information, thereby ensuring the correctness of the measurement results.

[0192] Furthermore, if the two satellites come from different ground observatories / ground base stations / ground gateways, the configuration information of the two overlapping satellites, and information on at least one of the SSB and CSI-RS can be exchanged between the ground observatories / ground base stations / ground gateways through the Xn interface, specifically including time information, resource code domain information and / or space information; further, the overlapping durations can be covered with each other, thereby avoiding incorrect measurement results caused by interference and resulting in switching failure.

[0193] Because on the terrestrial network, even if there is overlap between cells with the same frequency, it is only at the edges. However, in the nearly fixed scenario of the satellite network, the overlap between cells with the same frequency will be completely overlapped at certain times, which makes the interference problem more serious.

[0194] Therefore, according to the above, the communication method described in the embodiment of the present disclosure, according to the configuration information, distinguishes different first target objects that send the same PCI and / or the same SSB sequence, including:

[0195] Obtain, according to the configuration information, multiple different measurement configurations configured for the terminal by the serving cell according to one carrier / frequency band and for areas provided with services by different first target objects; or obtain multiple different measurement configurations configured for the terminal by the serving cell according to one carrier / frequency band;

[0196] According to the multiple different measurement configurations and the measurement configuration information, after performing differentiated measurements at corresponding resource locations, different first target objects with the same PCI and / or the same SSB sequence are sent distinguishably.

[0197] By adopting the communication method described in the embodiment of the present disclosure, the terminal can determine the different areas of at least one beam, at least one cell and at least one satellite according to the resource location of the first signal during the process of measuring the RSRP / RSRQ value of the first signal, and judge whether the service area and / or coverage area of ​​the current beam, cell and / or satellite belongs to a legal area by comparing with the allowed access area of ​​the terminal. When it is judged that it is not a legal area, the terminal triggers the execution of relevant operations, such as triggering cell switching or roaming request, to avoid invalid access or rejection by the network, which causes service interruption.

[0198] In the embodiment of the present disclosure, optionally, the method further includes:

[0199] Determine whether the measurement result of the signal of at least one beam, at least one cell and / or at least one satellite is greater than a first threshold value, such as the terminal measures the SSB in the first signal, and obtains at least one measurement result of RSRP, RSRQ, signal to interference plus noise ratio (SINR), CSI-RSRP, CSI-RSRQ and CSI-SINR corresponding to the first signal, and judge whether the measurement result is greater than the first threshold value; wherein the first threshold value is configured to the terminal by the network side, or determined by the terminal itself, and CSI is the channel state information reference signal (Channel State Information).

[0200] When the measurement result is greater than the first threshold value, it is determined whether the service area and / or coverage area provided by at least one beam, at least one cell and / or at least one satellite belongs to the restricted access area of ​​the terminal.

[0201] In which, when the network device sends corresponding relationship information to the terminal through a system message, optionally, the system message may also include a first threshold value of the measurement result of the signal of the terminal in the allowed access area. Through the first threshold value of the measurement result of the signal, it is determined that the measurement result of the signal of at least one beam, at least one cell and / or at least one satellite is greater than the first threshold value, and when it is determined based on the first information and / or the first signal that the provided service area and / or coverage area belongs to the allowed access area of ​​the terminal, normal signal transmission is performed in the current area, and the related operations are not performed.

[0202] The communication method described in the embodiment of the present disclosure performs a cell handover and / or roaming request when it is determined based on the first information and / or the first signal that the service area and / or coverage area provided by at least one beam, at least one cell, and / or at least one satellite belongs to the restricted access area of ​​the terminal. When performing a cell handover, the terminal can trigger the source network device to perform a cell handover on the terminal by sending a handover request to the source network device. Specifically, the terminal performs a cell handover and accesses an allowed access area near the current location, or switches to a terrestrial network cell.

[0203] In the embodiment of the present disclosure, the specific process of the terminal executing the cell switching and roaming request is not the focus of protection of the present disclosure and will not be described in detail here.

[0204] It should be noted that in the embodiment of the present disclosure, after cell switching, when the coverage range of the switched target cell includes multiple areas, the target cell and the source cell need to interact through the Xn interface to determine the resource location of the corresponding first signal transmission in different areas within the target cell.

[0205] In another implementation manner of the communication method described in the embodiment of the present disclosure, in step S110, the at least one beam and / or the at least one cell respectively send a beacon beacon code, wherein the first information is indicated by the beacon code, and the beacon codes are different when the service areas and / or coverage areas provided by the at least one beam and / or the at least one cell are different.

[0206] In this embodiment, the information about at least one beam and / or at least one cell transmitted by the network device includes, in addition to the first signal, a beacon code for distinguishing the area of ​​the beam and / or cell. The beacon code forms a secondary physical cell identification mechanism that can indicate one of the areas covered by the network device. The terminal parses the beacon code in the beam and / or cell and, based on the pre-acquired beacon codes corresponding to different areas, determines whether the service area and / or coverage area provided by the beam and / or cell falls within the terminal's restricted access area.

[0207] In this embodiment, optionally, the method further includes:

[0208] Determining a second resource location for sending the beacon code according to a first resource location for sending the first signal in the at least one beam and / or the at least one cell;

[0209] The second resource location and the first resource location satisfy a Quasi Co-Location (QCL) relationship.

[0210] In which, when the network device sends at least one beam and / or at least one cell, it sends different beacon codes corresponding to different areas, and the sent beacon code corresponds to the area of ​​at least one beam and / or at least one cell (for example, the area within the first beam and / or the first cell is divided into n areas, then the network sends n beacons corresponding to the n areas one by one; or, the area within the first beam and / or the first cell is divided into n areas, then the network sends m beacons corresponding to n areas m to n, and m and n in the full text are natural numbers greater than 0), and optionally, the beacon code and the corresponding area satisfy a second correspondence relationship, wherein the terminal can obtain the first correspondence relationship between the beacon code and the corresponding area through a system message, and determine the area indicated by the area indication information based on the first correspondence relationship and the beacon code.

[0211] In addition, when the network device sends at least one beam and / or at least one cell, it sends a first signal through a first resource location and sends a beacon code through a second resource location; wherein the second resource location and the first resource location satisfy a quasi-co-location QCL relationship.

[0212] Specifically, the network device sends a beacon code at a second resource location that satisfies a QCL relationship and is near a first resource location where a first signal is sent.

[0213] The terminal may obtain the second resource location and / or the quasi-co-location QCL relationship through a system message.

[0214] In this way, the terminal can identify the beacon code in the beam and / or cell at the second resource position based on the pre-obtained second resource position and / or the quasi-co-location QCL relationship, and the first resource position of at least one beam and / or at least one cell sending the first signal.

[0215] In this embodiment, optionally, the method further includes:

[0216] An access-stratum (AS) layer of the terminal parses a beacon code in the at least one beam and / or the at least one cell;

[0217] The Radio Resource Control (RRC) layer of the terminal obtains the beacon code parsed by the access AS layer, and determines a corresponding indication area according to the beacon code;

[0218] The non-access NAS layer of the terminal obtains the indicated area, determines whether the indicated area belongs to the restricted access area of ​​the terminal, and determines whether to perform relevant operations.

[0219] Specifically, when the access AS layer of the terminal parses the beacon code of the beam and / or cell, and parses and obtains the first resource location of the first signal sent by the beam and / or cell, the parsed beacon code and the first resource location of the first signal sent are sent to the RRC layer of the terminal. The RRC layer of the terminal determines the indication area corresponding to the beacon code in the beam and / or cell based on the first correspondence between the beacon code and the pre-obtained beacon code and the corresponding area, and sends the determined indication area to the NAS layer. The NAS layer obtains the indication area, determines whether the indication area belongs to the restricted access area of ​​the terminal, and determines whether to execute a cell switching and / or roaming request, and sends the judgment result to the AS layer of the terminal. The AS layer sends a cell switching request and / or roaming request to the network device.

[0220] In this embodiment, as in the previous embodiment, optionally, after cell switching, when the coverage of the switched target cell includes multiple areas, the target cell and the source cell need to exchange the beacon codes corresponding to different areas in the target cell through the Xn interface.

[0221] In addition, when the network device sends the first correspondence to the terminal through a system message, the system message may optionally also include a first threshold value of the measurement result of the signal of the terminal in the allowed access area. When the first threshold value of the measurement result of the signal is determined to be greater than the first threshold value, and when it is determined that the service area and / or coverage area of ​​the beam and / or cell belongs to the allowed access area of ​​the terminal, normal signal transmission is performed in the current area.

[0222] In another implementation manner of the communication method described in the embodiment of the present disclosure, optionally, the at least one beam and / or the at least one cell respectively include a Cell Global Identifier (CGI), wherein the first information is indicated by the CGI, and the service area and / or coverage area provided by the at least one beam and / or the at least one cell, and the CGI is different (for example, the area within the first beam and / or the first cell is divided into n areas, then the network sends n CGIs corresponding to the n areas one-to-one; or, the area within the first beam and / or the first cell is divided into n areas, then the network sends m CGIs corresponding to the n areas in an m-to-n manner, and m and n are natural numbers greater than 0 in the full text).

[0223] Optionally, the first information carries time information of providing services in different areas;

[0224] Alternatively, the network notifies the information of the time difference in providing services between areas.

[0225] In this embodiment, the first information about the at least one beam and / or the at least one cell sent by the network device includes a PCI and a CGI, where the CGI corresponds to the area of ​​the at least one beam and / or the at least one cell, with different areas corresponding to different CGIs. In this way, the terminal determines whether handover and / or roaming is required based on the received CGI (and optionally, the current location) from the at least one beam and / or the at least one cell.

[0226] Optionally, the terminal may obtain the positioning position of the Global Navigation Satellite System (GNSS) in a connected state, or obtain the positioning position by exiting the connected state and entering an idle state, or obtain the positioning position of the GNSS by starting to read the interval GAP of the GNSS.

[0227] Specifically, the terminal performs cell switching and can access an access-allowed area near the current location, or switch to a terrestrial network cell.

[0228] It should be noted that, in the embodiments of the present disclosure, the specific implementation method of sending the first information and / or the first signal through the network device to determine the service area and / or coverage area provided by the first target object is only for illustration and is not limited to this.
