Description

Background Art

[0002] With the rapid development of wireless communication technology, ISAC (integration of sensing and communication) technology, as a key technology of 6G (6th generation mobile networks), has attracted active research interest in recent years. By using the same frequency, waveform, infrastructure, etc. to achieve data transmission while extracting target information from scattered echoes, ISAC technology can greatly improve the spectrum, energy, and cost efficiency of sensing and communication functions. Single-base station ISAC is usually used in the existing technology. However, due to the existence of problems such as inter-cell interference, the perception and communication performance of single-base station ISAC are subject to certain limitations; and the existing technology also lacks a specific implementation method for multi-base station ISAC.

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0022] The exemplary embodiments of the present disclosure first provide a communication data processing method, which is applied to a multi-base station cooperative sensing system, and the multi-base station cooperative sensing system may include a first sensing base station and a second sensing base station. Among them, the multi-base station cooperative sensing system refers to a system that can cooperate through different base stations to support wireless sensing. The first sensing base station may refer to a base station that can send signals, and the second sensing base station may refer to a base station that can receive signals. It should be noted that "first" and "second" are only used as identifiers. In actual applications, the multi-base station cooperative sensing system may include multiple first sensing base stations, or multiple second sensing base stations, etc., and the present disclosure does not make specific limitations on this.

[0023] The following is combined with Figure 1 This exemplary embodiment is further described as follows. Figure 1 As shown, the communication data processing method may include the following steps S110 to S140:

[0024] Step S110: Send a perception connection request to a second perception base station through the first perception base station.

[0025] The first perception base station refers to a base station for sending data or signals, that is, a perception signal sending base station, and the second perception base station refers to a base station for receiving data or signals, that is, a perception signal receiving base station. The first perception base station and the second perception base station can perceive the perception objects in the environment by continuously sending and receiving signals. The transmitted data can be a sent perception signal, an echo signal returned by the perception object, a specific signal containing basic information of the base station or other information, or other signaling. The perception object can be any object that can be perceived, such as a vehicle, an aircraft, a terminal device, a ship, a drone, etc.

[0026] The perception connection request refers to request data sent by the first perception base station to the second perception base station for establishing a perception connection between the two base stations. After the first perception base station establishes a perception connection with the second perception base station, objects can be perceived in the environment based on the signal transmission between the base stations. The perception connection request may include information requesting to establish a connection, and may also include base station information of the first perception base station, such as identification information of the first perception base station, information of the base station group to which the first perception base station belongs, etc.

[0027] Step S120, in response to the second perception base station receiving the perception connection request sent by the first perception base station, when determining to establish a perception connection with the first perception base station, returning response information of the perception connection request to the first perception base station to establish a perception connection with the first perception base station.

[0028] After receiving the sensing connection request sent by the first sensing base station, the second sensing base station may return response information to the first sensing base station when it is determined that the sensing connection can be established with the first sensing base station, so as to inform the first sensing base station that the second sensing base station agrees to establish the sensing connection. The response information may include response information to the sensing connection request, such as agreeing to establish the connection, and may also include base station information of the second sensing base station, such as identification information of the second sensing base station, information of the base station group to which the second sensing base station belongs, etc. When the second sensing base station returns the response information of the sensing connection request to the first sensing base station, the sensing connection between the first sensing base station and the second sensing base station may be established. In the case of the sensing connection, the first sensing base station and the second sensing base station may detect whether a target object exists in the sensing environment by sending or receiving signals, and obtain dynamic information or static information of the sensed target object, etc.

[0029] Step S130, in response to detecting the target object, the second perception base station receives an echo signal about the target object and processes the echo signal to determine perception information from the echo signal; the perception information includes at least the signal quality of the echo signal, the position of the target object, the speed of the target object, and the moving direction of the target object.

[0030] The target object may be any perceptible physical object in the perception environment, such as an aircraft, a terminal device, a drone, a ship, etc. In the multi-base station cooperative perception system, the first perception base station and the second perception base station may transmit data signals in the perception environment by using the same frequency, waveform, and infrastructure to perceive the target object according to the scattered echo signal, and extract the perception information. The echo signal is a signal received by the second perception base station, which is a signal sent by the first perception base station and is returned by the target object through reflection or scattering. The signal strength of the echo signal may change compared to the initial signal sent by the first perception base station, but it may contain perception information about the perceived target object. In this exemplary embodiment, the perception information may include the signal quality of the echo signal, such as signal strength, signal continuity, etc., the position of the target object, such as the position of the drone in the perception environment, the position change, or the trajectory formed by the position change, etc., the speed of the target object, such as the moving speed of the drone in the perception environment, and the moving direction of the target object, such as the moving direction of the drone in the perception environment.

[0031] In this exemplary embodiment, after receiving the echo signal about the target object, the second perception base station can process the echo signal to extract perception information about the target object therefrom. The specific processing can be performed by a BSF (Base station Sensing Function) network element. For example, after receiving the echo signal, the second perception base station can send it to the BSF network element, and the BSF network element extracts the perception information from the echo signal and returns it to the second perception base station.

[0032] Step S140: Send the perception information to the first perception base station through the second perception base station.

[0033] Finally, the second perception base station may send the perception information of the detected target object to the first perception base station, so that each perception base station in the multi-base station cooperative perception system can synchronously perceive the information of the target object in the environment.

[0034] Figure 2 An interactive flow chart of a communication data processing method is shown, which is applied to a multi-base station cooperative sensing system. The multi-base station cooperative sensing system may include a sensing signal sending base station, i.e., a first sensing base station, and a sensing signal receiving base station, i.e., a second sensing base station. The sensing signal receiving base stations may be n, and may specifically include the following steps:

[0035] Step S210: The sensing signal sending base station sends a sensing connection establishment request to the sensing signal receiving base station;

[0036] Step S220: The sensing signal receiving base station returns response information of the sensing connection establishment request to the sensing signal sending base station;

[0037] Step S230, establishing a perception connection between the perception signal sending base station and the perception signal receiving base station;

[0038] Step S240: In response to detecting the target object, the sensing signal receiving base station receives an echo signal about the target object, and processes the echo signal to determine sensing information;

[0039] Step S250: The sensing signal receiving base station returns the sensing information to the sensing signal sending base station.

[0040] The sensing signal receiving base station in the above steps may be one or more of the n sensing signal receiving base stations. After receiving the sensing information, the sensing signal sending base station may aggregate the sensing information to integrate and manage the sensing information sent by different sensing signal receiving base stations.

[0041] Based on the above description, in this exemplary embodiment, a perception connection request is sent to a second perception base station through the first perception base station; in response to the second perception base station receiving the perception connection request sent by the first perception base station, when it is determined to establish a perception connection with the first perception base station, a response information of the perception connection request is returned to the first perception base station to establish a perception connection with the first perception base station; in response to detecting a target object, the second perception base station receives an echo signal about the target object and processes the echo signal to determine perception information from the echo signal; the perception information includes at least the signal quality of the echo signal, the position of the target object, the speed of the target object, and the moving direction of the target object; the perception information is sent to the first perception base station through the second perception base station. On the one hand, this exemplary embodiment proposes a new communication data processing method and provides a specific signal data processing flow, which can realize multi-base station collaborative perception of objects through data transmission between multiple perception base stations in a multi-base station collaborative perception system; on the other hand, compared with the single base station perception method in the prior art, the multi-base station collaborative perception in this exemplary embodiment decouples the signal sending base station from the signal receiving base station, so that the perception signal has stronger pertinence when being transmitted, enhances the functionality of each perception base station in the multi-base station collaborative perception system, and improves the effectiveness and accuracy of synaesthesia.

[0042] In an exemplary embodiment, the communication data processing method may include:

[0043] Acquire a plurality of sensing base stations for constituting a base station group in a multi-base station cooperative sensing system;

[0044] Signaling is sent to multiple perception base stations through the core network so that each perception base station determines the corresponding base station information; the base station information includes identification information of the perception base station, identification information of the base station group, and identity information of the perception base station.

[0045] Among them, the base station group refers to a set of perception base stations used to detect or perceive the target object in the multi-base station cooperative perception system, which may include multiple first perception base stations or multiple second perception base stations. All perception base stations in the multi-base station cooperative perception system can be added to the base station group, and some perception base stations can also be added to the base station group. For example, the multi-base station cooperative perception system includes 30 perception base stations, and 15 of them are added to the base station group. The multi-base station cooperative perception system may include multiple base station groups. For example, the multi-base station cooperative perception system includes 30 perception base stations, of which 20 perception base stations constitute base station group a, 10 perception base stations constitute base station group b, etc.

[0046] In this exemplary embodiment, after obtaining multiple perception base stations used to form a base station group in a multi-base station collaborative perception system, signaling can be sent to each base station through the SF (Sensing Function) network element of the core network to inform each perception base station of relevant base station information, such as identification information of the base station group, which can be numbers, characters or codes, used to indicate which base station group the current perception base station belongs to; identification information of the perception base station, such as the serial number and code of the perception base station; identity information of the perception base station, for example, the perception base station is the first perception base station used to send signals, or the identity information of the second perception base station used to receive signals; or it may also include working record information of the perception base station, such as information on establishing a perception connection in the historical records, information on the detected target object, and the time when the perception base station joined the multi-base station collaborative perception system, or the time when it was added to the base station group, or historical change records, etc.

[0047] After the first perception base station establishes a perception connection with the second perception base station, this information can be carried in the signal transmission among different perception base stations, such as in the request information for establishing the perception connection, or in the returned response information, etc. In addition, this information can also be sent separately, and the present disclosure does not make specific limitations on this.

[0048] In an exemplary embodiment, the communication data processing method may further include:

[0049] In response to the first perception base station receiving the perception information sent by multiple second perception base stations, information processing is performed on the perception information.

[0050] In this exemplary embodiment, the multi-base station collaborative perception system may include multiple second perception base stations. After determining the perception information, different second perception base stations can return the perception information to the first perception base station. The first perception base station can receive the perception information sent by multiple second perception base stations. In order to manage and analyze the perception information of the target object, the first perception base station aggregates the perception information after receiving the perception information sent by multiple second perception base stations. The information processing may include sorting and classification, aggregation and merging, deduplication, supplementation, correction, etc.

[0051] In an exemplary embodiment, the communication data processing method may further include:

[0052] In response to determining that the first perception base station is changed, canceling the perception connection between the first perception base station and the second perception base station.

[0053] The change of the first perception base station may include that the first perception base station that has established a perception connection currently exits the current base station group, or no longer has the function of sending signals, etc. In this case, the perception connection between the first perception base station that has established a perception connection and the second perception base station that has established a perception connection may be canceled. When there are multiple second perception base stations, the perception connections between the first perception base station that has established a perception connection and the multiple second perception base stations that have established a perception connection are canceled.

[0054] Specifically, this exemplary embodiment may determine through the SF network element that a change has occurred to the first perception base station. For example, the SF network element may determine whether the current first perception base station needs to be changed based on pre-configuration information or manual settings. For example, the configuration information may be that the first perception base station a may be used to establish a perception connection within a first time period, and the first perception base station b may be used to establish a perception connection within a second time period. Then, after entering the second time period from the first time period, the SF network element may determine that the first perception base station a needs to be changed. At this time, base station change information may be sent to the first perception base station a to inform the first perception base station a to cancel or to cancel the perception connection with the second perception base station, etc.

[0055] In an exemplary embodiment, the communication data processing method may further include:

[0056] In response to the first perception base station being changed to a third perception base station, determining a context information sender;

[0057] The context information is sent to the third perception base station through the context information sending direction, and after the third perception base station receives the context information, a perception connection between the third perception base station and the second perception base station is established.

[0058] Among them, the third perception base station refers to the perception base station used for sending signal data after the change, that is, the first perception base station and the third perception base station are both perception base stations used for sending signal data, and the first and third are only for identification, the difference is that the first perception base station is the old perception signal sending base station used before the perception base station is changed, and the third perception base station is the new perception signal sending base station used after the perception base station is changed. When it is determined that the first perception base station is changed to the third perception base station, for example, the core network SF network element determines that the first perception base station a used for sending signals exits the current base station group, and uses the third perception base station a to join the base station group to perform signal sending, that is, the first perception base station a is changed to the third perception base station a.

[0059] The context information may be the context information of the perception base station group, including the necessary information that the network needs to store when each base station in the base station group establishes a perception connection, such as a base station identifier, base station capability, authentication information, etc. The new perception base station can accurately and quickly join the perception base station group according to the context information, and establish a perception connection with other perception base stations. The context information sender refers to the information sender used to send the context information. In this exemplary embodiment, the context information sender may be the SF network element of the core network, or the perception signal sending base station before the change, that is, the first perception base station. The information sender may be determined by the core network SF network element, for example, it may be set in the SF network element in a pre-configured or customized manner, and the SF network element may determine the information sender, or the context information sender may be determined according to the current communication conditions and time constraints, for example, the core network SF network element may be used as the information sender first, and when the sending fails, the core network SF network element may be used; or the first perception base station may be used as the information sender in the first time period, and the SF network element may be used as the information sender in the second time period, and so on.

[0060] In this exemplary embodiment, if the core network SF network element determines that the SF network element is the sender of context information and informs the new perception signal sending base station, i.e., the third perception base station, the SF network element can send a perception base station activation notification to the third perception base station, and carry the context information of the perception base station group in the perception base station activation notification, so that the third perception base station receives the perception base station activation notification and determines that the corresponding perception function needs to be turned on while receiving the context information of the base station group.

[0061] If the core network SF network element determines that the first perception base station shall inform the third perception base station of the context information, the SF network element may carry this context information in the base station change notification. The first perception base station may first initiate an Xn interface connection establishment request to the third perception base station, and then send the context information to the third perception base station. After receiving the context information, the third perception base station may return a response message to the first perception base station.

[0062] In addition, after receiving the context information of the perception base station group, the third perception base station can perform a perception connection establishment process with the second perception base station in the group; finally, the third perception base station can send a change completion notification to the SF network element.

[0063] Figure 3 A sub-interaction flow chart of a communication data processing method in this exemplary embodiment is shown, which is applied to a multi-base station cooperative sensing system. The multi-base station cooperative sensing system may include a sensing signal sending base station and a sensing signal receiving base station. The sensing signal receiving base stations may be n, and may specifically include the following steps:

[0064] Step S302: In response to detecting that the old perception signal sending base station is changed to a new perception signal sending base station, the SF network element sends a base station change notification to the old perception signal sending base station via an AMF (Access and Mobility Management Function) network element;

[0065] Step S304: the old sensing signal sending base station sends a sensing connection deletion request to the sensing signal receiving base station;

[0066] Step S306: The sensing signal receiving base station returns response information of the sensing connection deletion request to the old sensing signal sending base station, so as to disconnect the sensing connection between the sensing signal receiving base station and the old sensing signal sending base station;

[0067] Step S308: If the core network SF network element determines that the new perception signal sending base station is notified by the SF network element, the SF network element sends a perception signal sending base station activation notification to the new perception sending base station, and carries the context of the perception base station group in the notification;

[0068] Step S310: If the core network SF network element determines that the old perception signal sending base station informs the new perception signal sending base station of context information, the SF network element carries the context information in the base station change notification;

[0069] Step S312: The old sensing signal sending base station initiates an Xn interface connection establishment request to the new sensing signal sending base station;

[0070] Step S314: The new sensing signal sending base station returns response information of the Xn interface connection establishment request to the old sensing signal sending base station;

[0071] Step S316: After establishing the Xn interface connection, the old sensing signal sending base station sends the context information of the sensing base station group to the new sensing signal sending base station;

[0072] Step S318: The new sensing signal sending base station returns response information after receiving the context information;

[0073] Step S320: After receiving the context information of the perception base station group, the new perception signal sending base station sends a perception connection establishment request to the perception signal receiving base station in the perception base station group;

[0074] Step S322: The sensing signal receiving base station in the sensing base station group returns response information of the sensing connection establishment request to the new sensing signal sending base station, so as to establish a sensing connection between the sensing signal receiving base station in the sensing base station group and the new sensing signal sending base station;

[0075] Step S324: The new perception signal sending base station sends an update completion notification to the SF network element through the AMF network element.

[0076] In an exemplary embodiment, the multi-base station cooperative sensing system includes a sensing base station group, and the sensing base station group includes a first sensing base station and a plurality of second sensing base stations; the communication data processing method may further include:

[0077] In response to determining that the target perception base station among the multiple second perception base stations exits the perception base station group, a change notification of the perception base station group is sent to the first perception base station, so that the first perception base station deletes the perception connection with the target perception base station.

[0078] Among them, the perception base station group is a group of perception base stations, which may include multiple perception base stations, such as one or more first perception base stations for signal transmission, and one or more second perception base stations for signal reception. The perception base station group will change with the change of the perception base stations therein. For example, the SF network element can determine which perception base station exits the perception base station group.

[0079] When it is determined that a target perception base station among multiple second perception base stations exits the perception base station group, for example, it is determined that a certain second perception base station no longer belongs to the perception base station group, a change notification of the perception base station group is sent to the first perception base station, wherein the target perception base station may be any one of the multiple second perception base stations, and may be determined by the SF network element, for example, the SF network element determines that the i-th second perception base station is exited from the current perception base station group, or when the i-th second perception base station fails, is idle, resting, is under high load, etc. and cannot continue to perform the perception task, the i-th second perception base station is used as the target perception base station, etc.

[0080] The change notification is notification information sent to the first perception base station that the perception base station group has changed, which may include the identifier of the changed base station group, the identifier of the changed perception base station, the identifier of the changed perception base station, or the reason for the change, the time of the change, etc. After the first perception base station receives the change notification of the perception base station group, it may initiate a perception connection deletion process with the target perception base station to disconnect the perception connection between the first perception base station and the target perception base station.

[0081] In an exemplary embodiment, the sending of the change notification of the perception base station group to the first perception base station may include:

[0082] Sending a first change notification to the first perception base station through the target perception base station; and / or

[0083] A second change notification is sent to the target perception base station through the perception function network element, and a first change notification is sent to the first perception base station.

[0084] In this exemplary embodiment, the SF network element of the core network may determine a target perception base station from among multiple second perception base stations, and may also determine who sends a change notification to the first perception base station.

[0085] Specifically, when it is determined that the target perception base station informs the first perception base station, the target perception base station can send a first change notification of the perception base station group to the first perception base station after receiving the notification from the SF network element, and the first perception base station can return corresponding response information after receiving the first change notification. When it is determined that the SF network element informs the first perception base station, the SF network element can send a second change notification to the target perception base station, and at the same time, send a first change notification of the perception base station group to the first perception base station. After receiving the first change notification of the perception base station group, the first perception base station can initiate a perception connection deletion process to the target perception base station. Finally, the first perception base station can send a notification message of the completion of the update of the perception base station group to the SF network element. Among them, the first change notification information is a change notification sent to the first perception base station, and the second change notification information is a change notification sent to the target perception base station. The two can be the same or different. For example, the second change notification information sent to the target perception base station can be a notification sent by the SF network element to the target perception base station to determine that the target perception base station will no longer be used and the target perception base station will be deactivated, so that the target perception base station knows that it will no longer belong to the perception base station group, which can be regarded as an instruction notification to the target perception base station; the first change notification information sent to the first perception base station can be an update notification or update status notification of the perception base station group sent by the SF network element to the first perception base station, which may include information about the perception base stations before and after the update in the updated perception base station group, information about the perception base stations that are still in the perception base station group, information about the perception base stations that have exited or are about to be withdrawn from the perception base station group, etc. The first perception base station can initiate a request to delete the perception connection with the target perception base station based on the first change notification.

[0086] Figure 4 Another sub-interaction flow chart of a communication data processing method in this exemplary embodiment is shown, which is applied to a multi-base station cooperative sensing system, where the multi-base station cooperative sensing system includes a sensing base station group, where the sensing base station group includes a sensing signal sending base station and multiple sensing signal receiving base stations, and specifically may include the following steps:

[0087] Step S402, in response to the core network SF network element determining that the nth sensing signal receiving base station among the multiple sensing signal receiving base stations no longer belongs to the sensing base station group, sending a sensing base station group change notification to the nth sensing signal receiving base station;

[0088] Step S404: When the SF network element determines that the nth sensing signal receiving base station informs the sensing signal sending base station, the nth sensing signal receiving base station sends a sensing base station group change notification to the sensing signal sending base station after receiving the sensing base station group change notification from the SF network element.

[0089] Step S406: The sensing signal sending base station returns response information after receiving the change notification;

[0090] Step S408, when the SF network element determines that the SF network element sends the perception base station group change notification, the SF network element sends the perception base station group change notification to the perception signal sending base station while sending the notification to the nth perception signal receiving base station;

[0091] Step S410: After receiving the change notification of the perception base station group, the perception signal sending base station sends a perception connection deletion request to the nth perception signal receiving base station;

[0092] Step S412: the nth sensing signal receiving base station returns response information of the sensing connection deletion request to the sensing signal sending base station;

[0093] Step S414: The perception signal sending base station sends notification information of the completion of the perception base station group update to the SF network element through the AMF network element.

[0094] In an exemplary embodiment, the multi-base station cooperative sensing system includes a sensing base station group, and the sensing base station group includes a first sensing base station and a plurality of second sensing base stations; the communication data processing method may further include:

[0095] In response to detecting that a new second perception base station joins the perception base station group, a change notification of the perception base station group is sent to the first perception base station.

[0096] In this exemplary embodiment, when a new second perception base station appears, for example, the SF network element determines to add a new perception signal receiving base station for receiving signal data to the perception base station group, at this time, the perception base station group will change, and a change notification of the perception base station group can be sent to the first perception base station.

[0097] Specifically, the SF network element of the core network may determine to whom the change notification is sent. In this exemplary embodiment, when the SF network element determines that the new perception signal receiving base station informs the first perception base station, the new second perception base station may send the third change notification of the perception base station group to the first perception base station after receiving the notification from the SF network element, and the perception signal sending base station may return a response message after receiving the message; when the SF network element determines that the SF network element sends the change notification of the perception base station group, the SF network element may send the third change notification of the perception base station group to the first perception base station while sending the fourth change notification to the new second perception base station. The third change notification is notification information sent to the first perception base station, which is used to inform the first perception base station about the change status of the perception base station group, such as the identifiers of the perception base stations before and after the change, the identifier of the newly added perception base station, etc. The first perception base station may establish a perception connection with the newly added second perception base station based on the third change notification; the fourth change notification is notification information sent to the newly added second perception base station, which is used to inform the newly added second perception base station that it is about to join the perception base station group, which may include the identifier of the base station group, etc.

[0098] After receiving the change notification of the perception base station group, the first perception base station can initiate a perception connection establishment process to the newly added second perception base station. Finally, the first perception base station can send a notification of the completion of the perception base station group update to the SF network element.

[0100] Step S502: in response to determining that a new sensing signal receiving base station m joins the sensing base station group, sending a sensing base station group change notification to the sensing signal receiving base station m;

[0101] Step S504: When the SF network element determines that the sensing signal receiving base station m informs the sensing signal sending base station, the sensing signal receiving base station m sends a sensing base station group change notification to the sensing signal sending base station after receiving the sensing base station group change notification sent by the SF network element.

[0102] Step S506: The sensing signal sending base station returns response information after receiving the change notification;

[0103] Step S508, when the SF network element determines that the SF network element sends the perception base station group change notification, the SF network element sends the perception base station group change notification to the perception signal sending base station while sending the notification to the perception signal receiving base station m;

[0104] Step S510: After receiving the notification of change of the sensing base station group, the sensing signal sending base station sends a sensing connection establishment request to the sensing signal receiving base station m;

[0105] Step S512: the sensing signal receiving base station m returns a response message of the sensing connection establishment request to the sensing signal sending base station, and establishes a sensing connection between the sensing signal receiving base station m and the sensing signal sending base station;

[0106] Step S514: The perception signal sending base station sends a perception base station group change completion notification to the SF network element through the AMF network element.
