[0024] The embodiments of this disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure. It should be noted that, unless otherwise specified, the embodiments of this disclosure and the features in the embodiments can be combined with each other.

[0025] For ease of understanding, the terminology used in the embodiments of this disclosure will be introduced first.

[0026] 1. Sensing Function

[0027] Sensing technology will become one of the core technologies of future communications. The typical application scenarios of sixth-generation mobile communication systems (6G) and sensing overlap by more than 80%, indicating deep integration between the two. The convergence of sensing networks and communication networks means that while providing communication, the communication network can also provide sensing functions. These sensing functions, as part of the network, thus provide sensing services.

[0028] 2. System Messages

[0029] System messages can be periodically broadcast messages by base stations (downlink) in mobile networks. Regardless of whether it's 5G or previous mobile networks, system messages are crucial information during the connection process between mobile terminals and base stations. In 5G networks, terminals power on, read system messages from the cell they are camping, and perform cell selection and reselection in the Radio Resource Control (RRC) idle state. System messages include basic network access information such as system frame number, system bandwidth, Public Land Mobile Network (PLMN), and cell selection and reselection thresholds.

[0030] From a high-level perspective, 5G (NR) system messages can be divided into the following three categories:

[0031] Basic System Messages (MSI); Other Basic System Messages (RMSI); Other System Messages (OSI).

[0032] 5G (NR) network system messages consist of Master Message Blocks (MIBs) and Other System Message Blocks (SIBs). MIB messages can be sent on the Broadcast Channel (BCH) and Physical Broadcast Channel (PBCH), while other messages are sent through the Downlink Shared Channel (DL_SCH) and Physical Downlink Shared Channel (PDSCH).

[0033] The basic system message block includes MIB and other basic system messages; other basic system messages include SIB1 and other system messages SIBx (X>=2); MIB and SIB1 correspond to the RRC "main information block" and "system information block" respectively, while SIBx (X>=2) are included in the RRC information corresponding to the "system message"; other system messages can be broadcast periodically with the basic system messages or sent by the network according to the terminal's request in dedicated mode. When OSI information is needed without a request, the terminal needs to know whether it exists in the cell and when it is broadcast; when in RRC_IDLE or RRC INACTIVE state, the terminal does not need to notify the base station and directly requests OSI messages; while in RRC CONNECTED state, the terminal requests OSI messages through RRC signaling; other system messages can be broadcast periodically according to the configuration; the network side notifies the connected terminal of the broadcast method of other system messages through RRC signaling.

[0121] A2. Network devices broadcast system messages. In some examples, network devices may broadcast system messages according to a broadcast cycle. Furthermore, to ensure that terminals accurately receive the system messages broadcast in this cycle, in some examples, the network device may send the broadcast cycle information to the terminal. This allows the terminal to receive the system message accurately when the network device broadcasts the message, based on the broadcast cycle information.

[0122] B2. Network devices send system messages to terminals via point-to-point wireless link connections. In some examples, terminals can proactively request system messages from network devices based on actual needs, and network devices can send the system messages to terminals via point-to-point wireless link connections based on the terminal's system message request. For example, network devices can send system messages directly to the terminal in a point-to-point manner through an established RRC connection.

[0123] In some embodiments, the system message may include SIB1, which may include resource scheduling information of a first SIB, and the resource scheduling information may be used to determine the time-frequency domain resources corresponding to the first SIB.

[0124] In some embodiments, the terminal may receive and parse the first SIB based on the resource scheduling information.

[0125] For example, after the terminal powers on, it executes a cell search procedure, decodes the Primary Synchronization Signal (PSS) and Secondary Synchronization Signal (SSS) to obtain the Physical Cell Identifier (PCI); then it scans the MIB message block to obtain the Global Synchronization Channel Number (GSCN) and acquires suitable Synchronization Signals (SS) / Physical Broadcast Channel (PBCH) information blocks; the MIB information is carried on the PBCH channel. After decoding the MIB information block, the terminal obtains the Control Resource Set (COREST); it searches the Physical Downlink Control Channel (PDCCH) to acquire and decode SIB1; SIB1 contains other information scheduling and network access parameters; among them, SIB1 includes the resource scheduling information of the first SIB, so the terminal can determine the time-frequency domain resources corresponding to the first SIB based on the resource scheduling information, and then receive and parse the first SIB based on the time-frequency domain resources.

[0126] In some embodiments, the network device may determine the characteristic information of the first terminal before sending a system message. For example, other terminals or network elements may send a request to the network device to locate the first terminal. This request may carry the characteristic information of the first terminal, and the network device may send a system message based on the request. The first SIB of the system message may include the characteristic information of the first terminal.

[0127] Step S202: The terminal receives a system message sent by the network device. Based on the feature information of the first terminal in the first SIB included in the system message, the terminal determines whether it is the first terminal that needs to be found.

[0128] In some embodiments, if the feature information of the first terminal matches the feature information of the terminal, it can be determined that the terminal is the first terminal to be found; if the feature information of the first terminal does not match the feature information of the terminal, it can be determined that the terminal is not the first terminal to be found.

[0129] For example, if the first terminal is at position A at 10:00, at position B at 10:05, and at position C at 10:10; and terminal n1 is also at position A at 10:00, at position B at 10:05, and at position C at 10:10, then terminal n1 is the first terminal we are looking for; terminal n2 is also at position A at 10:00, at position B at 10:05, but at position D at 10:10, then terminal n2 is not the first terminal we are looking for.

[0130] For example, if the first terminal is at position y on Avenue X at 11:00, moving at a speed of 60 km / h, and moving from north to south along Avenue X, and the object carrying the first terminal is a black sedan; and terminal n3 is also at position y on Avenue X at 11:00, moving at a speed of 60 km / h, and also moving from north to south along Avenue X, and the object carrying terminal n3 is also a black sedan, then terminal n3 is the first terminal we are looking for; terminal n4 is also at position y on Avenue X at 11:00, moving at a speed of 60 km / h, and also moving from north to south along Avenue X, but the object carrying terminal n4 is a white sedan, then terminal n4 is not the first terminal we are looking for.

[0131] In some embodiments, the terminal sends a response message to the network device, which can be used to indicate whether the terminal is the first terminal to be searched. If the terminal can send the response message to the network device regardless of whether it is the first terminal, the response message may include at least one of the following A3 to B3:

[0132] A3. A message that determines whether the terminal is the first terminal, such as a message that determines that the terminal is the first terminal, or a message that determines that the terminal is not the first terminal;

[0133] B3. The terminal's characteristic information, which allows network devices to determine whether it is the first terminal, etc.

[0134] Furthermore, in some embodiments, the response information may include: information indicating that the terminal is not the first terminal, and / or auxiliary information to assist in locating the first terminal, the auxiliary information including clues for locating the first terminal. This auxiliary information can be used to help the network device quickly find the first terminal. For example, the terminal can locate nearby first terminals using its own sensors based on the first terminal's characteristic information, and then send auxiliary information to the network device. This auxiliary information may include the relative position of the first terminal relative to the network device, so that the network device can locate the first terminal based on this relative position and the terminal's location.

[0135] In some embodiments, when a terminal determines that it is the first terminal based on the characteristic information of the first terminal, it sends a response message to the network device to confirm that the terminal is indeed the first terminal being sought. Conversely, when a terminal determines that it is not the first terminal based on the characteristic information of the first terminal, it may not send a response message to the network device.

[0136] In some embodiments, the first terminal may be a sensed object. For example, if the sensing function is part of the network and can provide sensing services, and the sensed object to be found is a terminal or an object carrying that terminal, in many cases, it is necessary to know the identity information of the sensed object so that it can be invoked by other processes, such as initiating a call by invoking the identity information of the sensed object through a process call. In this embodiment, the sensed object can be found through a specific first SIB in the system message. The first SIB includes the characteristic information of the sensed object. The sensed object that receives the system message can determine that the network device is looking for it based on the characteristic information, send a response message to the network device, and thus determine the identity of the sensed object.

[0137] In this embodiment, the network device can locate the first terminal through a specific first SIB in the system message. This first SIB includes the characteristic information of the first terminal. The terminal receiving the system message can then determine whether the network device is searching for it based on this characteristic information, thereby fulfilling more needs.
