[0054] It should be understood that the specific embodiments described herein are merely intended to explain the technical solutions of the present application, and are not intended to limit the present application.

[0055] In order to better understand the technical solutions of the present application, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0056] Based on this, the embodiments of the present application provide a wireless link connection establishment method, applied to a management station, referring to Fig. 1, Fig. 1 is a schematic flow diagram of a first embodiment of the wireless link connection establishment method of the present application.

[0057] In the present embodiment, the wireless link connection establishment method comprises steps S10-S40:

[0058] Step S10, based on the preset connection relationship between the management station and the terminal station, synchronizing with the target terminal station in uplink and downlink, the target terminal station including at least one accessible terminal station;

[0059] It should be noted that the current wireless communication mode includes the following four modes:

[0060] First, based on LTE (Long Term Evolution, long term evolution) or 5G NR (5G New Radio, 5G mobile communication network) wireless communication, the wireless access process of LTE or 5G NR includes: downlink synchronization, uplink synchronization, RRC (Radio Resource Control, Radio Resource Control) connection establishment and RRC connection reconfiguration, as shown in Fig. 2.

[0061] Among them, the downlink synchronization refers to the process of receiving the downlink synchronization signal and the system message by the terminal, and obtaining the downlink frame timing and timing synchronization; the uplink synchronization refers to the process that the terminal sends the uplink synchronization sequence to the base station according to the uplink synchronization configuration information carried in the system message, the base station receives the synchronization sequence to complete the contention resolution and issues the uplink timing adjustment for the terminal, and allocates the uplink resource for the terminal to transmit the RRC connection establishment request; the RRC connection establishment refers to the process that the base station allocates the physical configuration parameters for the terminal and establishes the default bearer after receiving the RRC connection establishment request of the terminal; the RRC connection reconfiguration refers to the process that the base station allocates the dedicated bearer wireless resource for the terminal.

[0062] Second, wireless communication based on WIFI (Wireless Local Area Network conforming to IEEE 802.11 standard), referring to FIG. 3, the access process of WIFI includes: Probe, Authentication, Association, wherein, if the algorithm type of the Authentication stage is Open System, then identity authentication of the EAPOL stage is also needed.

[0063] Among them, the Probe stage refers to discovering WIFI networks in the region by scanning, including active scanning and passive scanning, the STA (Station, user equipment) will broadcast and send Probe Request management frames to each channel in turn, and the AP (Access Point, access point) will reply with a Probe Response frame after receiving the Probe Request frame; passive scanning is that the STA passively receives the Beacon management frame sent by the AP, and only sends the Probe Request frame to the channel where the AP is located; the Authentication stage refers to that after the STA receives the Probe Response frame, it decides whether to join the network according to its own ability and the AP ability, if it decides to join, it sends an Authentication Request frame for identity authentication, otherwise the process ends; the Association stage refers to that if the STA receives the Authentication Success, it decides to join the network, then it sends an Association Request frame, indicating the network to be joined, its own Listen Interval (listening interval, i.e. how often the STA listens to the Beacon frame) and its own communication ability. The AP receives the Association Request frame and replies with an Association Response frame, indicating the success or failure of the association.

[0064] Third, wireless communication based on WIA-FA (Wireless Industrial Automation Fieldbus), WIA-FA is a wireless technical specification designed for high-speed automatic control applications in factories, referring to FIG. 4, the access process of WIA-FA includes:

[0065] The access device periodically sends a broadcast beacon frame; the field device to be accessed continuously monitors the available channel in the network, receives the beacon frame of the access device, and after the access device receives the joining request of the field device, the network management device (network manager) processes it; the network management device (network manager) feeds back the joining response; after the field device joins the WIA-FA network, the host computer requires the gateway device to read the UAO (User Access Override, a security feature in ARM architecture) of the field device by using the remote attribute reading service, and writes the configuration to the field device by using the remote attribute configuration service; the network management device (network manager) allocates communication resources for the field device by using the remote attribute configuration service, for communication between the field device and the access device.

[0066] Fourth, the wireless communication based on EUHT (Enhanced Ultra High Throughput), the network access process of the EUHT system refers to the process of discovering the network by the STA (Station) and establishing the connection with the CAP (Central Access Point), which includes three steps of acquiring system synchronization, random access process and capability negotiation, referring to Fig. 5.

[0067] The process of acquiring system synchronization by the STA is as follows: the STA scans the physical signal in a channel; if the STA correctly detects the physical frame header, it is considered that the channel has a physical frame, otherwise, it repeatedly detects until it switches to the next channel to continue the detection process after timeout; if the STA detects the physical frame and correctly analyzes the SICH (System Information Channel) and other information, it successfully acquires the system message, and the system initial synchronization is successful; the random access process of the STA is as follows: after the STA acquires the system information, it sends the random access sequence to the CAP according to the system information configuration, the CAP successfully receives the random access sequence, and allocates the uplink resource for the STA to send the random access request; the STA and the CAP interact with the random access request and response; the capability negotiation refers to that the STA informs the basic terminal communication capability of itself to the CAP by sending the terminal basic capability negotiation request frame, the CAP successfully receives it, compares the capability parameters, and includes the capability parameters supported by both parties, the resident channel allocated by the STA and the spectrum aggregation mode information in the terminal basic capability response frame, and sends the terminal basic capability response frame to the STA.

[0068] The process of establishing a wireless link connection of the above four wireless communication modes usually includes several main steps such as downlink synchronization, uplink synchronization, identity authentication, connection configuration and capability negotiation. In view of the uncertainty of the connection relationship between the access device and the accessed device, the terminal (STA) and the base station (AP, CAP) can judge whether to establish a wireless link connection based on information such as signal strength, identity authentication result, capability negotiation result, and the wireless link connection can be established when the preset conditions are met. Specifically, for the terminal, when there are multiple base stations that meet the conditions, one of them can be further selected to establish a wireless link connection according to the preset conditions; for the base station, when the preset conditions are met and the air interface resources can meet the service demand of the terminal, the base station can simultaneously establish a wireless link connection with multiple terminals.

[0069] However, due to the uncertainty between the access device and the accessed device in this process, complex signaling interaction processes are required to ensure the correctness of the wireless link establishment process or resource conflicts.

[0070] Specifically, the following three cases are used for illustration:

[0071] Case 1: In the uplink synchronization process, the uplink synchronization sequence and the resource used to send the uplink synchronization sequence are sent in a broadcast manner, and terminals within the coverage range can receive them. When multiple terminals simultaneously send the same uplink synchronization sequence to the base station using the same resource, resource conflicts will occur.

[0072] After the resource conflict occurs, the detection performance of the receiving end will be reduced due to interference, and the base station will also be unable to distinguish the uplink synchronization sequences sent by different terminals, or the base station can distinguish the uplink synchronization sequences sent by different terminals, but can only respond to one of the terminals, resulting in the failure of the other terminals to access this time.

[0073] Case 2: Due to the uncertainty of the connection relationship between the terminal and the base station, complex identity authentication is required between the terminal and the base station to ensure the identity of both parties, such as the identity authentication process of the terminal in the LTE / 5G-based wireless access process, which also requires the participation of the core network; in the WIFI-based wireless access process, the STA and the AP need to interact authentication (Authentication) information, etc.

[0074] Case 3: Since the base station can establish a wireless link connection with any terminal that meets the preset conditions, and different terminals may have different capabilities, in order to adapt to the capability differences of different terminals in the resource allocation process, the base station and the terminal need to interact the communication capability, such as the LTE / 5G-based wireless access process and the EUHT-based wireless access process, which involve signaling interaction processes related to capability negotiation.

[0075] Therefore, when the above wireless communication mode is applied to an industrial scene, due to the uncertainty of the connection between the management station and the terminal station in the process of establishing the wireless link connection, the above situation may exist, and therefore, a complex signaling interaction process is required to ensure the correctness of the wireless link connection establishment process.

[0076] For example, through multiple signaling interactions between the management station and the terminal station, it is determined whether the conditions for connection are met, and only when the conditions of both parties are met, the wireless link connection establishment can be realized, resulting in low access efficiency of the terminal station.

[0077] Specifically, in an industrial scene, since the layout of the device is relatively fixed, the data transmission path is also usually planned in advance, and therefore, the connection relationship between the terminal station and the management station can be notified to the management station through pre-configuration.

[0078] Since the connection relationship between the management station and the terminal station in the industrial scene is pre-configured, that is, the terminal stations that can access the management station are known, the management station performs uplink and downlink synchronization with at least one accessible terminal station (including a target terminal station) based on the pre-set connection relationship between the management station and the terminal station, which can eliminate the uncertainty of the access device and the accessed device in the wireless link connection establishment process, thereby improving the efficiency of uplink and downlink synchronization.

[0079] Among them, the accessible terminal station includes the terminal station involved in the pre-set connection relationship.

[0080] Step S20: based on the pre-set attribute information of the target terminal station, the communication configuration parameters are issued to the target terminal station, and the communication resources are allocated to the target terminal station, so that the target terminal station establishes the wireless link connection with the management station based on the communication configuration parameters and the communication resources.

[0081] Further, in order to avoid the complex interaction process between the terminal station and the management station, the attribute information of the terminal station can also be pre-informed to the management station through configuration.

[0082] Among them, the pre-set attribute information includes the identity information (MAC (Media Access Control Address, hardware address) address of the terminal station and network identifier of the terminal station), communication capability, location information, service demand, etc.

[0083] Therefore, in the process of establishing the wireless link connection between the terminal station and the management station, the management station does not need to obtain the attribute information of the target terminal station by interacting with the terminal station, but directly issues the communication configuration parameters to the target terminal station based on the pre-configured pre-set attribute information of the target terminal station, and allocates communication resources to the target terminal station, thereby simplifying the process of wireless link connection establishment, improving the utilization rate of air interface resources and access efficiency, and reducing the access delay.

[0084] In the embodiment, the wireless communication technology is applied to the industrial scene, the particularity of the industrial scene is fully utilized, the connection relationship between the terminal station and the management station and the attribute information of the terminal station are preconfigured, the management station can establish a wireless link connection with the terminal station based on the preset connection relationship and the attribute information, the terminal station and the management station do not need a complex terminal station communication capability interaction and an identity authentication process, a simplified wireless link connection establishment process, the terminal station (access device) access efficiency can be effectively improved, and access delay is reduced. Air interface resource conflicts are effectively avoided, wireless resources are reasonably allocated, and spectrum efficiency is improved.

[0085] Based on the first embodiment of the application, in the second embodiment of the application, the same or similar contents as the above embodiment one can be referred to the above introduction, and the following will not be repeated. On this basis, please refer to FIG. 6, step S10 includes steps A1-A4:

[0086] Step A1, broadcast the downlink synchronization signal and the downlink reference signal, so that the target terminal station determines the system message based on the downlink synchronization signal and the downlink reference signal, the system message includes at least one mapping relationship between the accessible terminal station and the uplink synchronization sequence, and the preset time domain position and the preset frequency domain position of the terminal station allocated for sending the uplink synchronization sequence, the mapping relationship is determined based on the preset connection relationship.

[0087] It should be noted that the downlink synchronization signal is used to ensure that the terminal station can accurately receive and identify the signal sent by the management station, and the downlink reference signal is used to help the terminal station to perform channel estimation, so that the terminal station correctly decodes the downlink data.

[0088] Specifically, the management station periodically broadcasts the downlink synchronization signal and the downlink reference signal at a fixed time domain position and a frequency domain position, as shown in FIG. 7, the downlink synchronization signal is broadcasted at the first OFDM symbol of the first slot of the radio frame, and the downlink reference signal is broadcasted at the second OFDM symbol of the first slot of the radio frame, and the frequency domain occupies the full bandwidth.

[0089] Further, the target terminal station receives the wireless signal at a certain frequency point, after receiving the downlink synchronization signal and the downlink reference signal, the target terminal station analyzes the downlink synchronization signal and the downlink reference signal, if the analysis is successful, the time-frequency position of the system message is determined according to the relative time relationship, and the system message is obtained; if the analysis fails, the signal of the next frequency point is continuously received.

[0090] The system message comprises at least one mapping relationship between an accessible terminal station and an uplink synchronization sequence, and a preset time domain position and a preset frequency domain position of the uplink synchronization sequence allocated to the at least one accessible terminal station; the mapping relationship between the at least one accessible terminal station and the uplink synchronization sequence is determined based on a preset connection relationship; the system message further comprises a system bandwidth, a system frame number, a radio frame structure, a number of antenna ports of a management station, a number of control channel symbols, a downlink synchronization signal energy per resource element, a downlink synchronization signal power offset, and the like.

[0091] Specifically, the MAC address of the terminal station and the network identity of the terminal station can be determined based on the preset connection relationship; the mapping relationship can be a corresponding relationship between the MAC address and the network identity and the uplink synchronization sequence; in order to facilitate the target management station to determine the uplink synchronization sequence corresponding to itself, the system message further comprises the MAC address of the terminal station and the network identity of the terminal station.

[0092] The management station can broadcast the system message through one system message or through multiple system messages; if the system message is broadcast through multiple system messages, the time and frequency positions of the other system messages are indicated in the first system message; the terminal station can acquire the other system messages based on the time and frequency scheduling information after acquiring the first system message.

[0093] In step A2, the target uplink synchronization sequence sent by the target terminal station, and a target time domain position and a target frequency domain position of the target uplink synchronization sequence are acquired.

[0094] Specifically, the system message further comprises uplink synchronization related information: an uplink synchronization sequence acquired according to an uplink synchronization sequence index, an initial transmission power of the uplink synchronization sequence, and an uplink synchronization sequence transmission power adjustment step.

[0095] The terminal station can acquire the uplink synchronization related information from the system message; the terminal station determines the uplink synchronization sequence and the preset time domain position and the preset frequency domain position of the uplink synchronization sequence based on the uplink synchronization related information; and the terminal station transmits the uplink synchronization sequence corresponding to itself at the preset time domain position and the preset frequency domain position.

[0096] Suppose the target terminal station transmits the uplink synchronization sequence on the first OFDM symbol of the first uplink time slot in the Kth radio frame, the management station receives the uplink synchronization sequences sent by the terminal stations; if the target uplink synchronization sequence sent by the target terminal station is received, the management station can determine the target time domain position and the target frequency domain position of the target uplink synchronization sequence sent by the target terminal station based on the time and frequency positions of the target uplink synchronization sequence.

[0097] Step A3, determine whether the correspondence between the target terminal station and the target uplink synchronization sequence is consistent with the mapping relationship, and determine whether the target time domain position and the target frequency domain position are consistent with the preset time domain position and the preset frequency domain position corresponding to the target uplink synchronization sequence respectively.

[0098] It can be understood that if the management station parses the target uplink synchronization sequence sent by the target terminal station on the corresponding wireless frame, it is considered that the target terminal station is an accessible terminal station configured in the system message, and if the correspondence between the target terminal station and the target uplink synchronization sequence is consistent with the mapping relationship, and the target time domain position and the target frequency domain position are consistent with the preset time domain position and the preset frequency domain position corresponding to the target uplink synchronization sequence respectively, the management station considers that the target terminal station is a correctly accessed terminal station.

[0099] Therefore, the management station needs to determine whether the correspondence between the target terminal station and the target uplink synchronization sequence is consistent with the mapping relationship, and determine whether the target time domain position and the target frequency domain position are consistent with the preset time domain position and the preset frequency domain position corresponding to the target uplink synchronization sequence respectively; if one of them is inconsistent, the uplink synchronization with the target terminal station cannot be completed.

[0100] Step A4, if they are consistent, the uplink synchronization with the target terminal station is performed.

[0101] Further, if the correspondence between the target terminal station and the target uplink synchronization sequence is consistent with the mapping relationship, and the target time domain position and the target frequency domain position are consistent with the preset time domain position and the preset frequency domain position corresponding to the target uplink synchronization sequence respectively, the management station performs uplink synchronization with the target terminal station.

[0102] Specifically, the management station responds to the target terminal station to allow uplink synchronization, and the target terminal station adjusts the time alignment amount to ensure correct synchronization of signals, thereby realizing uplink synchronization between the management station and the target terminal station.

[0103] It should be noted that the preset attribute information includes the communication capability of the target terminal station, and the communication configuration parameter includes the configuration parameter of the uplink and downlink between the target terminal station and the management station.

[0104] Wherein, after the management station performs uplink synchronization with the target terminal station, the specific implementation of the management station issuing the communication configuration parameter to the target terminal station based on the preset attribute information of the target terminal station is:

[0105] Based on the communication capability of the target terminal station, the configuration parameter of the uplink and downlink is determined; the configuration parameter of the uplink and downlink is issued to the target terminal station.

[0106] Specifically, communication capabilities include data transmission capabilities, frequency band support capabilities, carrier aggregation capabilities, etc. Based on the communication capabilities of the target terminal station, the management station can determine the uplink and downlink configuration parameters; among which, the uplink and downlink configuration parameters include at least one of the following:

[0107] Uplink timing adjustment command: used by the terminal station to adjust the uplink data transmission timing;

[0108] Uplink scheduling authorization: used by the terminal station to send the initial connection configuration response message; uplink power control related parameters: used for power adjustment of the uplink channel or signal.

[0109] Downlink power allocation related parameters: used for power adjustment of downlink channels or signals;

[0110] Transmission mode related parameters: MIMO transmission mode used for management stations and / or terminal stations;

[0111] Uplink quasi-channel state measurement and / or feedback-related parameters: used for uplink quasi-channel state measurement;

[0112] Parameters related to downlink quasi-channel state measurement and / or reporting: used for downlink quasi-channel state measurement.

[0113] Specifically, the management station sends the aforementioned uplink and downlink configuration parameters to the target terminal station; based on the uplink and downlink configuration parameters, the target terminal station performs network configuration to achieve wireless link connection.

[0114] It should be noted that communication resources include time-domain and frequency-domain resources for service data transmission. The specific implementation method for the management station to allocate communication resources to the target terminal station after uplink synchronization with the target terminal station is as follows:

[0115] Based on the downlink synchronization signal or downlink reference signal, determine the channel state of the downlink, and based on the uplink synchronization signal or uplink reference signal, determine the channel state of the uplink; based on the channel states of the downlink and the uplink, allocate the time domain resources and frequency domain resources required for service data transmission to the target terminal station.

[0116] Among them, business data transmission refers to the business transmission between the management station and the terminal station.

[0117] Specifically, the management station and the terminal station measure the signal quality of the downlink synchronization signal or downlink reference signal and the uplink synchronization signal or uplink reference signal respectively (e.g., measuring performance indicators such as bit error rate and signal-to-noise ratio) to determine the channel state of the downlink and the channel state of the uplink. If the terminal station participates in the measurement, it reports the measurement results to the management station, which then determines the channel state of the downlink and the channel state of the uplink based on the measurement results.

[0118] The downlink synchronization signal and the downlink reference signal are transmitted by the management station based on a preset broadcast mode (periodic broadcast at a fixed time-frequency position), and the uplink synchronization signal and the uplink reference signal are transmitted by the target terminal station after completing downlink synchronization. The uplink reference signal (uplink synchronization sequence) is transmitted by the target terminal station at a preset time domain position and a preset frequency domain position based on the information related to the uplink synchronization obtained from the system message.

[0119] Since the positions of the devices are relatively fixed in the industrial scenario, and the wireless environment is relatively stable, the channel state obtained through continuous measurement can be used to allocate semi-static scheduling for periodic services. Therefore, the time domain resources and the frequency domain resources (semi-static scheduling resources) required for the target terminal station to transmit service data can be allocated based on the channel state of the downlink and the channel state of the uplink.

[0120] It should be noted that the preset information further includes the service requirement of the target terminal station, and the communication configuration parameter further includes the resource configuration parameter of the time domain resource and the frequency domain resource. The specific implementation of the management station issuing the communication configuration parameter to the target terminal station after uplink synchronization with the target terminal station is as follows:

[0121] Based on the service requirement of the target terminal station, the resource configuration parameter of the time domain resource and the frequency domain resource corresponding to the target terminal station is determined, and the resource configuration parameter of the time domain resource and the frequency domain resource is issued to the target terminal station.

[0122] Specifically, the service requirement can be determined based on the QoS (Quality of Service) requirement of the service model of the target terminal station, wherein the QoS requirement includes the service packet size, the service packet transmission period, and the delay requirement, and the service model can be obtained by the management station through pre-configuration and wireless signaling interaction.

[0123] Further, the management station determines the resource configuration parameter of the time domain resource and the frequency domain resource corresponding to the service data transmission of the target terminal station based on the service requirement of the target terminal station, wherein the resource configuration parameter includes at least one of the following:

[0124] The configuration parameter can include one or more combinations of the following:

[0125] Service identification: used to uniquely identify a service;

[0126] Service type: used to distinguish real-time services or non-real-time services;

[0127] Service transmission direction: used to distinguish uplink transmission services or downlink transmission services;

[0128] Transmission channel identifier: used for uniquely identifying a transmission channel;

[0129] Service period: the transmission interval of service data packets, only applicable to periodic services;

[0130] Service packet length: the data size of a single service packet;

[0131] Service priority: the priority of the service, which can be used to determine the packet priority order when multiple services are multiplexed.

[0132] Further, the management station issues resource configuration parameters of time domain resources and frequency domain resources to the target terminal station, and the target terminal station can establish a data transmission channel for the service according to the above resource configuration parameters, ensuring that the QoS requirement of the service can be met.

[0133] In the embodiment, the management station and the target terminal station perform uplink and downlink synchronization; based on preset attribute information of the target terminal station, the management station issues communication configuration parameters to the target terminal station and allocates communication resources to the target terminal station; based on the service requirement of the target terminal station, the management station determines resource configuration parameters of time domain resources and frequency domain resources corresponding to the target terminal station, and issues the resource configuration parameters of the time domain resources and the frequency domain resources to the target terminal station in a manner of realizing connection establishment of a wireless link; in this process, the management station does not need to obtain attribute information of the target terminal station by interacting with the terminal station, but directly issues communication configuration parameters to the target terminal station based on the preset attribute information of the target terminal station configured in advance, and allocates communication resources to the target terminal station, thereby simplifying the process of wireless link connection establishment, improving air interface resource utilization and access efficiency, and reducing access delay.

[0134] Based on this, the embodiment of the application further provides a wireless link connection establishment method applied to a terminal station, as shown in FIG. 8, which is a flowchart of a third embodiment of the wireless link connection establishment method of the application.

[0135] In the embodiment, the wireless link connection establishment method comprises steps P10-P30:

[0136] Step P10, based on a preset connection relationship between the management station and the terminal station, performing uplink and downlink synchronization with a target management station, the target management station comprising at least one accessible management station.

[0137] Since the connection relationship between the management station and the terminal station in the industrial scenario is preconfigured, that is, the management stations accessible to the terminal station are known, the terminal station performs uplink and downlink synchronization with at least one accessible management station based on the preset connection relationship between the management station and the terminal station, which can eliminate the uncertainty of the access device and the accessed device in the wireless link connection establishment process, thereby improving the efficiency of uplink and downlink synchronization.

[0138] Specifically, based on the preset connection relationship between the management station and the terminal station, the specific implementation of uplink synchronization with the target management station includes:

[0139] The terminal station receives the downlink synchronization signal and the downlink reference signal sent by the target management station, the downlink synchronization signal and the downlink reference signal are sent by the target management station based on the preset broadcast mode; based on the downlink synchronization signal and the downlink reference signal, the system message is determined, the system message includes at least one mapping relationship between the accessible terminal station and the uplink synchronization sequence, and the preset time domain position and the preset frequency domain position of the uplink synchronization sequence allocated for at least one accessible terminal station, the mapping relationship is determined based on the preset connection relationship; based on the target uplink synchronization sequence corresponding to the local, the uplink synchronization with the target management station is requested.

[0140] Specifically, the terminal station receives the wireless signal at a certain frequency point, after receiving the downlink synchronization signal and the downlink reference signal sent by the target management station based on the preset broadcast mode, the terminal station parses the downlink synchronization signal and the downlink reference signal, if the parsing is successful, the time-frequency position of the system message is determined according to the relative time relationship, and the system message is obtained; if the parsing fails, the signal of the next frequency point is continuously received.

[0141] Among them, the preset broadcast mode is periodically broadcasted in fixed time domain position and frequency domain position.

[0142] Further, the terminal station determines the target uplink synchronization sequence corresponding to the local based on the mapping relationship, specifically, since the mapping relationship can be the corresponding relationship between the MAC address, network identifier and the uplink synchronization sequence, the terminal station can locate the target uplink synchronization sequence in the mapping relationship based on the local MAC address or network identifier, and determine the preset time domain position and the preset frequency domain position of the uplink synchronization sequence.

[0143] Among them, based on the target uplink synchronization sequence corresponding to the local, and the target time domain position and the target frequency domain position corresponding to the target uplink synchronization sequence, the specific implementation of requesting uplink synchronization with the target management station is:

[0144] The terminal station sends the target uplink synchronization sequence at the target time domain position and the target frequency domain position to request the uplink synchronization with the target management station.

[0145] Further, if the target management station determines that the corresponding relationship between the terminal station and the target uplink synchronization sequence is consistent with the mapping relationship, and determines that the target time domain position and the target frequency domain position are consistent with the preset time domain position and the preset frequency domain position corresponding to the target uplink synchronization sequence, the target management station responds to the terminal station to allow the uplink synchronization, the terminal station adjusts the time alignment amount to ensure the correct synchronization of the signal, so as to realize the uplink synchronization between the target management station and the terminal station.

[0146] Step P20, receiving the communication configuration parameters issued by the target management station, and determining the communication resources allocated by the target management station, wherein the communication configuration parameters and the communication resources are determined by the target management station based on the preset attribute information of the terminal station.

[0147] Specifically, after the uplink synchronization with the terminal station, the target management station issues the communication configuration parameters to the terminal station based on the preset attribute information of the terminal station, and allocates the communication resources to the terminal station; the terminal station receives the communication configuration parameters issued by the target management station, and determines the communication resources allocated by the target management station.

[0148] In this process, the terminal station does not need to inform the target management station of the local attribute information by interacting with the target management station, and the target management station can directly issue the communication configuration parameters to the terminal station and allocate the communication resources to the terminal station based on the preset attribute information of the terminal station pre-configured, which simplifies the process of wireless link connection establishment, improves the air interface resource utilization and access efficiency, and reduces the access delay.

[0149] Step P30, based on the communication configuration parameters and the communication resources, performing the wireless link connection establishment with the target management station.

[0150] Further, the terminal station can perform the wireless link connection establishment with the target management station based on the communication configuration parameters and the communication resources.

[0151] The communication resources include the time domain resources and the frequency domain resources for service data transmission, and the communication configuration parameters include the configuration parameters of the uplink and downlink between the target terminal station and the management station, and the resource configuration parameters of the time domain resources and the frequency domain resources.

[0152] The specific implementation of the wireless link connection establishment with the target management station based on the communication configuration parameters and the communication resources is as follows:

[0153] Based on the configuration parameters of the uplink and downlink, the network configuration is performed to realize the wireless link connection; based on the time domain resources and the frequency domain resources and the resource configuration parameters, the resource configuration is performed to realize the wireless link establishment.

[0154] Specifically, the terminal station configures the terminal station layer entities (for example, the physical layer, the network layer, the transmission layer, and the application layer, and the device and service configuration of multiple layers) based on the communication configuration parameters, completes the initial connection establishment, and feeds back the wireless link connection completion to the target management station.

[0155] In the embodiment, the terminal station synchronizes with at least one accessible management station (including the target management station) based on a preset connection relationship between the management station and the terminal station. It can be understood that, since the connection relationship between the management station and the terminal station in the industrial scenario is preconfigured, that is, the management station accessible to the terminal station is known, the uncertainty of the access device and the accessed device in the wireless link connection establishment process is eliminated. In addition, the terminal station does not need to inform the target management station of the local attribute information by interacting with the target management station, and the target management station can directly distribute the communication configuration parameter to the terminal station based on the preset attribute information of the terminal station, and allocate the communication resource to the terminal station, thereby simplifying the process of wireless link connection establishment, improving the air interface resource utilization rate and access efficiency, and reducing the access delay.

[0156] Exemplarily, in order to facilitate understanding of the implementation process of the wireless link connection establishment method obtained after the above-mentioned embodiment one, please refer to FIG. 9, which provides a brief flowchart of a wireless link connection establishment method, specifically including the following steps:

[0157] Step 0: The management station periodically transmits the downlink synchronization signal and the downlink reference signal at a fixed time-frequency position.

[0158] Step 1: The target terminal station receives the wireless signal at a certain frequency point, and after receiving the downlink synchronization signal and the downlink reference signal, the target terminal station analyzes the downlink synchronization signal and the downlink reference signal. If the analysis is successful, the system message is determined according to the relative time relationship, the system message is obtained, and the uplink synchronization sequence is transmitted according to the system message.

[0159] Step 2: The management station configures the uplink and downlink configuration parameters related to the wireless connection establishment for the terminal station after verifying the uplink synchronization sequence of the terminal station.

[0160] Step 3: The terminal station applies the uplink and downlink configuration parameters distributed by the management station to complete the initial connection establishment, and feeds back to the management station. The downlink time-frequency synchronization and the uplink timing synchronization between the terminal station and the management station are completed.

[0161] Step 4: The management station configures the resource configuration parameters for configuring the time domain resource and the frequency domain resource for the terminal station to establish the business transmission channel.

[0162] Step 5: The management station and the terminal station respectively measure the uplink reference signal and the downlink reference signal, and determine the quasi-static channel information (channel state) of the uplink wireless channel and the downlink wireless channel based on the measurement results.

[0163] Step 6: The management station allocates the semi-static scheduling resource (time domain resource and frequency domain resource) for the business based on the quasi-static channel information obtained in step 5, for the periodic data transmission of the business.

[0164] The steps 4 and 5 have no time sequence limitation, and the step 5 is a continuous channel monitoring process.
