[0082] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0083] To make the application scenarios of the embodiments of the present invention clearer, the relevant technologies involved in the embodiments of the present invention will first be introduced:

[0084] In the prior art, the system messages are usually broadcast periodically. There are generally three types of system broadcast messages: Master Information Block (MIB), System Information Block 1 (SIB1), and system messages that carry other system messages (Other SI, OSI).

[0085] There are two scheduling methods for MIB messages: In Long Term Evolution (LTE), the cycle is 40ms, and the cycle is repeated 4 times, which means broadcasting once every 10ms; In New Radio (NR), the cycle is 80ms, and the number of Synchronization Signal Blocks (SSBs) sent in each cycle depends on the different subcarriers and frequency bands, and the direction of each SSB is different.

[0086] There are two ways to schedule SIB1 messages: in LTE, it is an 80ms cycle, repeated 4 times per cycle, which means broadcasting once every 20ms; in NR, it is a 160ms cycle, and the repetition cycle depends on the network implementation.

[0087] The scheduling process for SI messages is as follows: The position and period of the SI message in the time domain are specified by SIB1. The base station uses SIB1 to inform the terminal device which SIs exist, which SIBs each SI contains, which SI windows these SIs will be sent in, and the time domain position and length of the SI window. However, it does not inform the terminal device which subframes within the SI window schedule the SI. When the terminal device needs a particular SIB, it will attempt to decode it in each subframe of the SI window corresponding to that SIB (starting from the initial subframe of the SI window and lasting for the SI window length (si-WindowLength) subframes, excluding subframes where SIs cannot be scheduled), until it successfully receives the SI message.

[0088] Another system message sending method is the onDemand-based system message mechanism introduced in 5G. Terminal devices can actively obtain specified system messages, but a connection establishment process is required, which can be based on a non-contention-based method or a contention-based method.

[0089] The aforementioned method of periodically broadcasting system messages consumes a significant amount of limited air interface resources. While the OnDemand-based system message mechanism introduces a way for terminal devices to actively acquire system messages, it is not applicable in the following scenarios: first, it only works for OSI messages, not MIB and SIB1 messages; second, it is not applicable to terminal devices accessing the network for the first time, or those that have not been synchronized; and third, it is not applicable to terminal devices that need to reconnect after losing network connection or synchronization.

[0090] Based on the above, this embodiment of the invention is designed for industry field networks where terminal devices are basically fixed. It eliminates the air interface resources occupied by periodic broadcast messages and instead uses system messages to be obtained when the terminal devices need them. This applies to all system messages and can make use of these air interface resources to greatly improve network capacity and network performance.

[0091] See Figure 1 , Figure 1 This is a flowchart of a system message sending method provided in an embodiment of the present invention, applied to a terminal device, such as... Figure 1 As shown, the method includes the following steps:

[0092] Step 101: Send an excitation signal to the base station, wherein the excitation signal is used to trigger the base station to broadcast system messages.

[0093] In this embodiment of the invention, when the terminal device needs to access the network, an excitation signal can be generated. For example, a signal of a specific frequency can be generated as an excitation signal, or a radio wave can be generated by a specific circuit as an excitation signal. Then, the excitation signal is sent to the base station to trigger the base station to broadcast system messages. The device can then receive the system messages broadcast by the base station, realize the active acquisition of system messages, and access the network based on the system messages.

[0094] The scenarios in which the terminal device accesses the network include, but are not limited to, initial access, re-searching for the network after a network outage, and resynchronization after the loss of synchronization signals. That is, the terminal device can trigger the base station to broadcast system messages by sending an excitation signal to the base station at any time when it needs to access the network, thereby replacing the existing periodic broadcasting method and realizing on-demand broadcasting of system messages.

[0095] The system messages may include one or more of the main information block (MIB) messages, SIB1 messages, and OSI messages. That is, the terminal device can obtain OSI messages in this way, and it is also effective for MIB and SIB1 messages. Compared with the existing system message mechanism based on OnDemand that is only effective for OSI, the application scenarios of this invention are more extensive and flexible.

[0096] Optionally, the terminal device is provided with an excitation module;

[0097] Before step 101, the method further includes:

[0098] The excitation module is controlled to generate the excitation signal.

[0099] In one embodiment, an excitation function can be integrated on the terminal device side, that is, an excitation module can be set in the terminal device to generate an excitation signal, which can be a radio wave signal or a radio frequency signal.

[0100] Specifically, when the terminal device needs to access the network, it can control the excitation module to generate an excitation signal and send the excitation signal to the base station, thereby triggering the base station to broadcast system messages. More specifically, the terminal device can send a control signal to the excitation module through the L3 layer of the protocol layer, namely the Radio Resource Control (RRC) layer, to trigger the excitation module to generate an excitation signal and send the excitation signal to the base station.

[0101] In this way, the required excitation signal can be generated by the excitation module to excite the base station to start the system message broadcast process, which is easy to implement.

[0102] Step 102: Receive the system message broadcast by the base station.

[0103] Upon receiving the excitation signal, the base station can initiate system message broadcasting under the excitation effect of the signal. Specifically, the broadcasting of the system message can be triggered through the L3 layer (RRC layer) of the base station's protocol layer. More specifically, it can trigger a timed, periodic system message broadcast, meaning the system message can be broadcast continuously for a certain duration, stopping broadcasting after the timeout to avoid excessive occupation of air interface resources.

[0104] After the base station broadcasts the system message, the terminal device can receive the system message and access the network based on the system message.

[0105] In one embodiment, after successfully receiving the system message, the terminal device may return an indication message to the base station to indicate that the system message has been successfully received, and the base station may stop broadcasting the system message.

[0106] Optionally, step 102 includes:

[0107] Listen to the system messages broadcast by the base station;

[0108] If the system message is not received within a preset time period, the step of sending an excitation signal to the base station is repeated until the system message broadcast by the base station is received.

[0109] In one embodiment, the terminal device can listen to the system messages broadcast by the base station after sending an excitation signal to the base station. If the system messages are received normally, the device can access the network based on the system messages. However, if the system messages are not received within a timeout period, for example, if the system messages are not received for more than a preset time, it is possible that the excitation signal failed to reach the base station or that the base station malfunctioned, resulting in the failure to trigger the system message broadcast. Therefore, step 101 can be re-executed to re-excite the base station to trigger the system messages. If the system messages broadcast by the base station are successfully received, the repetition of step 101 can be stopped.

[0110] This ensures that the terminal device can successfully receive the system messages broadcast by the base station, avoiding the failure to obtain system messages in some cases.

[0111] Optionally, the excitation signal is used to activate the wake-up module or RFID module in the base station to trigger the protocol layer in the base station to broadcast the system message.

[0112] In one embodiment, at least one of a wake-up module and a radio frequency identification (RFID) module can be integrated on the base station side. The wake-up module or the RFID module can be woken up or activated under the excitation signal. After activation, the wake-up module or the RFID module can trigger the protocol layer in the base station to broadcast the system message.

[0113] The wake-up module can be a passive wake-up radio circuit, which, upon being excited by an excitation signal (such as radio waves), reflects radio waves to generate voltage or current, thereby waking up or activating the passive wake-up circuit and triggering a protocol layer broadcast system message in the base station. The RFID module can be an RFID tag, which, under the excitation of an excitation signal (such as a radio frequency signal), converts signal energy into voltage, thereby activating the RFID tag and triggering a protocol layer broadcast system message in the base station.

[0114] In this way, by setting up a wake-up module or radio frequency identification (RFID) module on the base station side, it can cooperate with the excitation module in the terminal device to trigger the broadcast of system messages, which is not only easy to implement, but also has a low implementation cost.

[0115] Specifically, when the wake-up module or the RFID module in the base station triggers the protocol layer in the base station to broadcast the system message after activation, it can be as follows:

[0116] An interrupt signal is generated by the wake-up module or the RFID module, and the interrupt signal is transmitted to the driver layer in the base station;

[0117] The interrupt signal is converted into a command message by the driver layer and transmitted to the protocol layer in the base station. The command message is used to instruct broadcast system messages.

[0118] The system message is broadcast through the protocol layer.

[0119] In one embodiment, the wake-up module or the RFID module can generate an interrupt signal after activation and transmit the interrupt signal to the driver layer of the base station. The driver layer can then convert the interrupt signal into a command message that the protocol layer can recognize. After receiving the command message, the protocol layer can trigger the broadcast of the system message.

[0120] In this way, the implementation method can ensure that the trigger command is transmitted layer by layer to the protocol layer, thereby ensuring the accurate broadcast of system messages.

[0121] Optionally, after step 101 and before step 102, the method further includes:

[0122] A target command is sent to the base station so that the protocol layer in the base station broadcasts a target system message corresponding to the target command, wherein different commands correspond to different system messages;

[0123] Step 102 includes:

[0124] Receive the target system message broadcast by the protocol layer in the base station.

[0125] In one implementation, the correspondence between commands and system messages can be predefined, and then specific commands can be sent to the base station to trigger the base station to broadcast specific types of system messages, thereby achieving more precise control over system messages.

[0126] Specifically, the terminal device can predefine the correspondence between commands and system messages. For example, it can define that the first command corresponds to a MIB message, the second command corresponds to a SIB1 message, the third command corresponds to an OSI message, and so on. Furthermore, the terminal device can agree on the correspondence between commands and system messages with the base station. That is, the terminal device can send the correspondence to the base station so that when the base station subsequently receives a corresponding command from the terminal device, it can determine the corresponding system message needed by the terminal device based on the correspondence.

[0127] In this embodiment, after the terminal device sends an excitation signal to the base station to activate the wake-up module or the RFID module in the base station, it can further send a target command to the base station according to the type of system message to be obtained, so as to trigger the base station to broadcast the corresponding target system message according to the target command.

[0128] Upon receiving the target command, the base station can determine the target system message corresponding to the target command based on a pre-agreed command-system message correspondence with the terminal device, thereby triggering the protocol layer in the base station to broadcast the target system message, so that the terminal device can receive the target system message.

[0129] Specifically, the base station may also be equipped with a decoding module, which can be a decoding circuit or a main circuit. After the wake-up module or the RFID module is activated, it can further activate the decoding module to decode the received target command, determine the specific command content of the target command, and the decoding module can transmit the decoded target command to the protocol layer in the base station. The protocol layer can then broadcast a target system message corresponding to the target command based on the decoded target command content. More specifically, the decoding module can transmit the decoded target command to the L1 layer (physical layer) of the base station's protocol layer. The L1 layer then converts the content of the target command into a command message recognizable by the L3 layer (RRC layer) of the base station's protocol layer and transmits the command message to the L3 layer. The L3 layer triggers the broadcast of the target system message based on the command message.

[0130] In this way, different system messages can be obtained through different commands, thereby achieving precise control over system messages.

[0131] Optionally, sending the target command to the base station includes:

[0132] A signal at a target frequency is generated and sent to the base station, wherein different frequencies correspond to different commands, and the signal at the target frequency corresponds to the target command;

[0133] Alternatively, the target command corresponding to the target system message may be sent to the base station, wherein the target command is written into the user data area of ​​the RFID module.

[0134] In one specific implementation, the terminal device can send target commands to the base station in different ways. For example, it can use multi-frequency technology or encoding technology, or write commands into the user data area of ​​the RFID tag to send different commands.

[0135] In one implementation, multi-frequency technology can be used to send target commands. Specifically, different frequency signals can be predefined to correspond to different commands, and different commands can correspond to different system messages. Thus, different commands can be represented by signals of different frequencies. Therefore, in implementation, a signal of the corresponding target frequency can be generated according to the required target system message and sent to the base station. After receiving the signal of the target frequency, the base station can put the signal of the target frequency into the decoding module for decoding to obtain the corresponding target command content, and then trigger the broadcast of the target system message corresponding to the target command.

[0136] In another implementation, different encodings can be used to distinguish different commands, such as Dual Tone Multi-Frequency (DTMF) encoding, Pulse Interval Encoding (PIE) encoding, etc. This allows the receiver, such as the base station, to identify different commands sent by the terminal based on the correspondence between different encodings and commands, and thus make different responses, that is, to return the target system message corresponding to the target command to the terminal.

[0137] In another implementation, the target command can be sent by writing commands to the user data area of ​​the RFID tag. Specifically, different system messages corresponding to different commands can be predefined. During implementation, the corresponding target command can be written to the user data area of ​​the RFID module in the base station according to the required target system message. The base station can read the target command from the user data area of ​​the RFID module and pass it to the decoding module for decoding to obtain the corresponding target command content, thereby triggering the broadcast of the target system message corresponding to the target command.

[0138] Thus, in this embodiment, the target command can be sent by transmitting a signal at the target frequency or by writing the target command into the user data area of ​​the RFID module, thereby achieving accurate acquisition of system messages, and this method is easy to implement.

[0139] The following is combined Figures 2 to 4 The specific implementation methods of the embodiments of the present invention are illustrated by examples:

[0140] The embodiments of the present invention can be applied to Figure 2 The network architecture shown is as follows: Figure 2 As shown, the passive wake-up radio or RFID tag is integrated into the base station side, which is the hardware layer of the base station, while the excitation module is integrated into the terminal device side.

[0141] When a terminal device needs to access the network, its L3 protocol layer control excitation module transmits an excitation signal to activate the Passive Wake-up Radio circuit or RFID tag on the base station side. Upon activation, the base station's Passive Wake-up Radio circuit or RFID tag converts the excitation signal energy into voltage and generates an interrupt signal to the driver layer. The driver layer then converts the interrupt signal into a command message and reports it to the L3 protocol layer. The base station's L3 layer triggers a timed, periodic system message broadcast, for example, a 60-second timer. The broadcast stops when the timer expires, until the next trigger command arrives. The terminal device attempts to listen for the system broadcast message over the air interface; if no system message is received within the timeout period, the excitation signal is retransmitted.

[0142] like Figure 3 As shown, the embodiments of the present invention can be applied to scenario one, that is, without distinguishing the system message type, the base station triggers the broadcast of all system messages after being stimulated.

[0143] like Figure 3 As shown, in this scenario, the interaction process between the terminal device and the base station is as follows:

[0144] 1) The excitation signal is triggered by the terminal device;

[0145] 2) When the passive wake-up circuit or RFID tag on the base station side is activated, an interrupt signal is generated to the base station's driver layer.

[0146] 3) The driver layer converts the message into a command message and sends it to the L3 layer. The L3 layer then returns an acknowledgment (ACK) message to the driver layer.

[0147] 4) L3 layer triggers system message broadcast

[0148] 5) Timeout stops broadcast system message

[0149] 6) If the terminal device does not receive a system message within the timeout period, the above process will be repeated.

[0150] like Figure 4 As shown, the embodiments of the present invention can be applied to scenario two, that is, distinguishing system message types and triggering the base station to broadcast the corresponding system message according to the different commands sent by the terminal device.

[0151] like Figure 4 As shown, in this scenario, the interaction process between the terminal device and the base station is as follows:

[0152] 1) The excitation signal is triggered by the terminal device;

[0153] 2) After the passive wake-up circuit or RFID tag on the base station side is activated, the decoding circuit or main circuit is activated;

[0154] 3) The terminal device initiates a system message request and carries a specific command in the request. Specifically, it can request one or more system messages. For example, it can use multi-frequency technology or write commands to the user data area of ​​the RFID tag.

[0155] 4) The decoding circuit or main circuit sends the decoded command to the L1 layer;

[0156] 5) The L1 layer generates a command message for the L3 layer, and the L3 layer returns an ACK message to the L1 layer;

[0157] 6) L3 layer triggers broadcast of specific system messages
