[0075] In the conventional technology, the research and implementation of the communication awareness fusion technology mainly consider the awareness effect in a single base station, and when the target to be sensed moves between different base stations, the awareness blind area or poor awareness effect can occur for a period of time due to the change of the base station for sensing.

[0076] Based on the conventional technology, the target awareness method provided in the embodiments of the present application can obtain the second base station on the moving path of the target device according to the moving information of the target device, that is, the base station to which the target device can move, during the sensing of the target device by the first base station, and then the first base station sends an awareness service advance instruction to the second base station, and the second base station performs a preparation operation for sensing the target device according to the awareness service advance instruction, so that the target device can be sensed in time when the target device enters the sensing range of the second base station, which can improve the awareness effect when the base station is changed, and avoid the poor awareness effect for a period of time due to the lack of awareness preparation of the target device by the second base station when the target device switches from the first base station to the second base station.

[0077] It should be noted that the beneficial effects or technical problems solved by the embodiments of the present application are not limited to one, but can also be other implicit or related problems, and the specific problems can be referred to the description of the following embodiments.

[0078] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific examples. The following specific examples can be combined with each other, and the same or similar concepts or processes can not be described again in some examples. The embodiments of the present application will be described below with reference to the drawings.

[0079] In one embodiment, as shown in Figure 2 , a target awareness method is provided, which is applied to the first base station in Figure 1 for example, and includes the following steps:

[0080] Step 201, in the process of awareness of the target device, the first base station acquires at least one second base station according to the moving information of the target device.

[0081] Among them, the second base station is the base station on the moving path of the target device, that is, the base station in the area where the target device may move in the moving process, and the first base station is the base station currently aware of the target device. The target device can be a wireless terminal, which can be a device that provides voice and / or other service data connectivity to a user, or a handheld device with wireless connection function or other processing device connected to a wireless modem. The wireless terminal can communicate with one or more core networks through a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal, for example, it can be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network. The wireless terminal can also be called system, subscriber unit, subscriber station, mobile station, mobile, remote station, remote terminal, access terminal, user terminal, user agent, user device or user equipment, which is not limited here.

[0082] When the first base station is in the process of sensing the target device, when it is sensed that the target device gradually moves from the center of the cell to the edge of the cell in the moving process, the first base station can acquire the moving information of the target device, which can optionally include the direction and distance of the movement of the target device, or the position information of the target device, and can also include the time and speed of the movement of the target device. According to the moving information of the target device, the moving path of the target device is determined, and at least one second base station on the moving path of the target device is acquired.

[0083] In step 202, the first base station sends a sensing service advance instruction to the second base station.

[0084] The sensing service advance instruction is used to instruct the second base station to perform the preparation operation of sensing the target device.

[0085] After the first base station acquires the second base station according to the moving information of the target device, the first base station sends a sensing service advance instruction to the second base station, and the second base station performs the preparation operation of sensing the target device according to the received sensing service advance instruction, that is, the second base station prepares to sense the target device in advance. Optionally, the second base station can generate a corresponding sensing beam according to the moving information of the target device, so that when the target device moves from the first base station to the second base station, the second base station has generated a corresponding sensing beam, and can timely sense the target device.

[0086] Optionally, the first base station can forward through the core network device, or send the sensing service advance instruction to the second base station through the inter-station interface between the first base station and the second base station.

[0087] In the above target sensing method, first, in the process of sensing the target device, at least one second base station on the moving path of the target device is acquired according to the sensed moving information of the target device, and then a sensing service advance instruction for instructing the second base station to perform the preparation operation of sensing the target device is sent to the second base station. In this way, in the process of sensing the target device by the first base station, the second base station on the moving path of the target device, that is, the base station that the target device can move to, is acquired according to the moving information of the target device, and then the first base station sends a sensing service advance instruction to the second base station. The second base station performs the preparation operation of sensing the target device according to the sensing service advance instruction, so that the target device can be sensed in time when it enters the sensing range of the second base station, which can improve the sensing effect during base station replacement and avoid the situation that the sensing effect is poor for a period of time when the target device is switched from the first base station to the second base station due to the lack of sensing preparation of the target device by the second base station.

[0088] In one embodiment, the step of acquiring the at least one second base station according to the perceived movement information of the target device comprises Figure 3 The method can comprise:

[0089] At step 301, the first base station sends trigger information to the core network device.

[0090] The trigger information carries the movement information of the target device, and the trigger information is used to instruct the core network device to determine the at least one second base station according to the movement information of the target device. The first base station can send the trigger information to the core network device if the target device meets a preset condition.

[0091] Optionally, the preset condition can be that the trigger information is sent to the core network device if it is determined according to the movement information that the distance between the target device and the first base station is greater than a preset distance threshold. The preset condition can also be that the first base station sends the trigger information to the core network device if the signal strength of the target device is less than a preset signal strength threshold. The preset condition can also be that the first base station sends the trigger information to the core network device when an indication signal sent by the target device is received. The preset distance threshold can be set according to the perception coverage range of the first base station, and optionally can be set to 50 meters. The movement information of the target device can include the distance between the target device and the first base station, and when the distance between the target device and the first base station is greater than the preset distance threshold, the preset condition is met, at this time the target device moves from the center to the cell edge within the coverage range of the first base station, and the first base station sends the trigger information to the core network device.

[0092] At step 302, the first base station receives base station indication information sent by the core network device based on the trigger information.

[0093] The base station indication information is used to indicate the at least one second base station. The base station indication information can be geographic location information of the at least one second base station. The core network device determines the at least one second base station on the movement path of the target device based on the trigger information sent by the first base station, then acquires the geographic location information of the at least one second base station from an external server, and then sends the location information of the second base station to the first base station. The base station indication information can also be distance information between the first base station and each second base station calculated by the core network device after acquiring the geographic location information of the first base station and the at least one second base station.

[0094] In the above embodiment, when the first base station determines that the target device moves from the cell center to the cell edge, the first base station sends the trigger information to the core network device, the core network device determines the base station indication information, i.e. the at least one second base station, according to the trigger information, and the trigger information includes the movement information of the target device. Since the at least one second base station is determined according to the movement information of the target device, the accuracy of the determination of the second base station can be improved.

[0095] In one embodiment, before the first base station sends the sensing service advance instruction to the second base station, the first base station determines a second base station meeting a condition from at least one second base station according to the movement information of the target device, and the second base station meeting the condition is usually one, i.e., the base station about to sense the target device, and the method specifically comprises: if the sensing result of the first base station on the target device meets a preset condition, the first base station sends the sensing service advance instruction to the second base station.

[0096] Optionally, the sensing result comprises movement information and signal quality of an echo of the target device detected by the first base station, and the sensing result of the first base station on the target device meets a preset condition, wherein the preset condition comprises: if it is determined according to the movement information that the position of the target device between the first base station and the second base station meets a preset position condition, and the signal quality meets a preset quality condition, it is determined that the sensing result meets the preset condition.

[0097] The preset position condition comprises a condition that a ratio of a distance between the target device and the first base station to a distance between the first base station and the second base station is greater than a preset ratio, and / or the preset quality condition comprises a condition that the signal quality is worse than a preset signal quality threshold.

[0098] Optionally, as described above, the base station indication information can be geographic position information of the at least one second base station, or distance information between the first base station and each second base station. Taking the geographic position information of the at least one second base station as an example, the first base station acquires the geographic position information of the first base station and the geographic position information of the second base station sent by the core network device, and then determines the distance between the first base station and the second base station according to the geographic position information of the first base station and the geographic position information of the second base station. The preset ratio is a ratio set according to different scenarios, for example, it can be 1 / 3, i.e., when the ratio of the distance between the target device and the first base station to the distance between the first base station and the second base station is greater than 1 / 3, the preset position condition is met.

[0099] Meanwhile, the preset quality condition can also be included, and the preset quality condition is used to judge the quality of the signal, and when the signal quality deteriorates, i.e., the target device is about to reach the cell edge of the first base station. The signal quality of the preset quality condition can be judged by detecting the signal-to-noise ratio of the echo, and the preset signal quality threshold is a threshold value, which can be set according to different scenarios, and when the value of the signal-to-noise ratio of the detected echo is lower than the preset signal quality threshold, the preset quality condition is met.

[0100] In the above embodiment, the first base station determines a second base station meeting a condition from at least one second base station, and then sends the sensing service advance instruction to the second base station, thereby avoiding sending to multiple second base stations for sensing preparation operation, and causing waste of resources.

[0101] After receiving the sensing service advance instruction sent by the first base station, the second base station performs a preparation operation for sensing the target device. The preparation operation can include, but is not limited to, generating a directional beam for sensing the target device. The second base station senses the target device through the directional beam. The preparation operation can also include determining other parameters for sensing the target device.

[0102] In the above embodiment, the second base station generates a directional beam for sensing the target device according to the sensing service advance instruction sent by the first base station, so that when the target device moves from the first base station to the second base station, the second base station can generate a directional beam or adjust the direction of the existing directional beam in time, so that the sensing effect is not poor for a certain period of time.

[0103] In one embodiment, as shown in Figure 4 , a target sensing method is provided. The method is applied to a core network device in Figure 1 for example, and includes the following steps:

[0104] In step 401, the core network device receives trigger information sent by a first base station.

[0105] The trigger information carries the movement information of a target device sensed by the first base station. After receiving the trigger information sent by the first base station, the core network device obtains the geographical position information of the first base station from an external server.

[0106] In step 402, the core network device determines at least one second base station according to the movement information.

[0107] The second base station is a base station on the movement path of the target device. The target area on the movement path of the target device is determined according to the movement information, and at least one second base station is determined according to the base stations in the target area.

[0108] The movement information of the target device can include the direction and distance of the movement of the target device. The core network device can determine a target area where the target device is about to move according to the direction and distance of the movement of the target device. The core network device stores a topology graph of the base stations, and through the topology graph, the base stations in the target area are determined as the second base stations. The second base stations include at least one, or multiple. Optionally, the multiple second base stations can be further screened, such as screening according to the distance between the first base station and the second base station, or screening according to the services of the multiple second base stations in the target area, and finally determining at least one second base station.

[0109] In step 403, the core network device sends base station indication information to the first base station.

[0110] The base station indication information is used to indicate at least one second base station, and the second base station is used for the first base station to send the sensing service advance instruction to the second base station, wherein the sensing service advance instruction is used to instruct the second base station to perform the preparation operation of sensing the target device.

[0111] After the at least one second base station is determined, the core network device sends the base station indication information to the first base station. The base station indication information can be the geographic position information of the at least one second base station obtained by the core network device from an external server, or the core network device can calculate the distance between the first base station and the at least one second base station by using the obtained geographic position information of the at least one second base station and the geographic position information of the first base station, and then send the distance to the first base station, so that the first base station performs the final screening to determine the second base station.

[0112] Optionally, the movement information includes the position of the target device and the moving direction of the target device, and the step of determining the target area on the moving path of the target device according to the movement information comprises: Figure 5 The method can comprise:

[0113] In step 501, the core network device determines a target sector area with the position of the target device as the center of a sector and the moving direction of the target device as the center line of the sector.

[0114] The target sector area is a sector area on the moving path of the target device determined according to the movement information of the target device. The center of the sector is the position of the target device, the center line of the sector is the moving direction of the target device, and the length of the sector can be set according to the environment, which is 300 meters optionally. The angle of the sector is 120 degrees. A target sector area is determined according to the above parameters.

[0115] In step 502, the core network device takes the target sector area as the target area.

[0116] The target sector area is the area that the target device can reach during the moving process. The target sector area is taken as the target area, and the target area is used to determine the at least one second base station.

[0117] Optionally, after the target area is determined, the at least one second base station is determined according to the base stations in the target area, which comprises: determining the at least one second base station from the base stations in the target area according to the distance between each base station in the target area and the first base station.

[0118] Since the number of base stations in the target area can be large, the core network device selects a preset number of base stations close to the first base station in the target area as the second base station. The preset number can be set according to requirements, and is generally a positive integer greater than 1. Optionally, the position of the target device can be determined according to the movement information of the target device, and a preset number of base stations close to the target device in the target area can also be selected as the second base station.

[0120] In step 601, the second base station receives the awareness service advance instruction sent by the first base station for the target device.

[0121] In step 602, the second base station performs a preparation operation for awareness of the target device according to the awareness service advance instruction.

The preparation operation can include: generating a pointing beam for awareness of the target device according to the movement information of the target device carried in the awareness service advance instruction.

[0123] Optionally, the direction of the pointing beam needs to be determined before the pointing beam is generated, and the determination step of the direction of the pointing beam is as shown in Figure 7 , and includes:

[0124] In step 701, the second base station determines the azimuth information of the target device relative to the second base station according to the movement information.

[0125] The movement information of the target device includes the direction of movement of the target device. The direction of movement of the target device can be represented by the horizontal direction angle between the first base station and the target device. According to the direction of movement of the target device and the horizontal direction angle between the first base station and the second base station, the vertical direction angle between the target device and the second base station can be calculated, so as to obtain the azimuth information of the target device relative to the second base station.

[0126] The specific calculation method can refer to Figure 8 , wherein the direction of movement of the target device, i.e., the horizontal direction angle between the first base station and the target device, is represented by α, the horizontal direction angle between the first base station and the second base station is represented by β, and the distance between the first base station and the target device is represented by d. The length of the target fan-shaped area in the figure is 300 meters, and the preset number is 4, i.e., four base stations closest to the first base station in the target fan-shaped area are selected as the second base station T n , n is 1 to 4. The first base station and each second base station Tn The distance between the target device and the second base station T1 is d n As known from the above, the second base station satisfying the preset condition is determined according to the movement information of the target device in at least one second base station, and the sensing service advance instruction is sent to the second base station. In the figure, the second base station T1 is determined as the second base station satisfying the preset condition through calculation, the second base station T1 receives the sensing service advance instruction, and the direction information of the target device and the second base station T1 is calculated, that is, the vertical direction angle γ between the target device and the second base station T1.

[0127] Optionally, the calculation method of γ is as shown in the following formula:

[0128]

[0129] In step 702, the second base station generates a pointing beam according to the direction information.

[0130] The second base station T1 generates a pointing beam according to the direction of the above direction information, which is used for sensing the target device.

[0139] At step 906, if the sensing result of the target device by the first base station meets the preset condition, the first base station sends the sensing service advance instruction to the second base station. The sensing result includes the movement information and the signal quality of the echo of the target device detected by the first base station. The preset condition includes: if it is determined according to the movement information that the position of the target device between the first base station and the second base station meets the preset position condition, and the signal quality meets the preset quality condition, it is determined that the sensing result meets the preset condition.
