Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
The concept of the present invention is explained below with reference to the accompanying drawings.
Method for identifying relative position of user equipment
Fig. 1 is a schematic diagram of relative positions of a user equipment and a service device according to an embodiment of the present invention.
First, the original location of the ue is a1, the original location of the service device is B1, and the ue sends a message to notify the service device to rendezvous to a certain location or area, i.e. the dashed line in the figure corresponds to the location a2 of the ue. When the service device receives the information sent by the user device, it will go from location B1 to location B3 to rendezvous with the user device. When the user equipment and the service equipment meet with each other, the user equipment and the service equipment go to the destination according to the information of the user equipment.
Fig. 2 is a flowchart of determining relative positions of a ue and a service device according to an embodiment of the present invention, and fig. 3a and 3b are schematic diagrams of a first relative position and a second relative position of the ue and the service device, respectively.
S21: user equipment sends out service demand information
In this step, the user device will send service demand information to the network or service system through the client based on its own demand. The demand information at least comprises first position information, and the first position information at least comprises current position information and/or designated position information of the user equipment. For example, one or more of a location of the user device, a destination where the user device desires to rendezvous may be included.
Step S22: the service equipment receives the service requirement information
In this step, the plurality of service devices will acquire the service demand information from the user device, and at least one service device will send information that it is desired to provide a service to the server.
Step S23: determining a first service device providing a service
In this step, the server will determine that the user equipment is served by the first service device based on the received at least one piece of information desired to serve.
Preferably, the server will determine the first service device based on the response information of the plurality of service devices and/or the locations of the plurality of service devices. It is understood that the response information from the plurality of service apparatuses includes response times of the plurality of service apparatuses.
Step S24: and respectively acquiring the position information of the user equipment and the first service equipment.
In this step, the user equipment and the first service equipment will upload their location information, respectively, to determine the distance d between the user equipment and the first service equipment.
As can be seen from fig. 3, the starting point a1 of the ue has coordinates of (x)A1，yA1) The coordinate of the end point A2 is (x)A2，yA2) The starting point B1 coordinate of the first service device is (x)B1，yB1) The coordinate of the end point B3 is (x)B3，yB3) Wherein the first service device passes through point B2 (x) in the process of moving from point B1 to point B2B2，yB2)。
When the user equipment and the first service equipment reach points a1 and B2, respectively, in order to determine whether the two will be combined, the distance d between the two needs to be calculated. Since the user equipment and the first service equipment are often in a non-stationary state, a time factor needs to be considered when calculating the distance d.
In this embodiment, the ue uploads its location information periodically, that is, the time interval between two adjacent coordinates of the ue is T1, for example, the location information is uploaded every 5 to 15 seconds after the user sends the service requirement information. Likewise, the first service device also periodically uploads its location information, with a time interval between two adjacent coordinates of T2, such as every 5 to 15 seconds after the first service device has been or preempted. If the time for uploading the position information by the user equipment and the first service equipment is synchronous, only the distance between the two coordinate points needs to be calculated; if the two times for uploading the location information are not synchronized, not only the coordinates of the user equipment but also the location uploaded by the first service equipment in the time period corresponding to the coordinates are determined. In this embodiment, the distance between the user equipment and the first service equipment is calculated every 5 to 15 seconds.
Assuming that the ue and the first service device are both moving, it is first determined whether the coordinate a2 of the ue is on the line segment at the projection point along the connecting line of B3 and B2. If the projected point is not on the line segment, the distance between the ue and the first service device is the connection line between the two coordinates that are latest in time, i.e. the situation shown in fig. 3 a.
Fig. 3B shows the case where the projected point is on a line segment, and the distance d needs to be obtained by calculating the distance from the point a2 to the connecting line between the points B2 and B3. If the point A2 corresponds to the time tA2, the points B2 and B3 correspond to the times tB2 and tB3 respectively, and the sequence of the three times is as follows: tB2, tA2, tB 3.
A may be connected to each of the three points to form a triangle, and three sides of the triangle are a ═ A2B2|, B ═ A2B3|, and c ═ B2B3|, so that the area S of the triangle is:
where p is half the perimeter of the triangle, i.e. p can be expressed as:
thus, S can be expressed as:
thus, the distance from point A2 to segment B2B3 can be expressed as:
as can be seen from the above, when the ue and the first service device merge and move in the same direction, the method shown in fig. 3b can effectively and quickly determine the distance between the ue and the first service device.
Step S25: and judging whether the relative distance is less than or equal to a first threshold value and the duration is greater than or equal to a second threshold value.
When the distance d between the user equipment and the first device determined through the step S24 is less than or equal to the first threshold and the time for maintaining the state is greater than or equal to the second threshold, it may be considered that the user equipment and the service equipment have successfully conferenced (step S26), otherwise, it is considered that the user equipment and the service equipment have not conferenced (step S27).
Preferably, the first threshold is 5 meters and the second threshold is 180 seconds.
It can be understood that the user equipment may also send the service requirement information only when the service is needed, and after sending the service requirement information, the user equipment continuously uploads the location information thereof; if the user equipment does not need service for a long time, it will not upload its location information.
Fig. 4 is a schematic architecture diagram of a ue according to an embodiment of the present invention.
The user equipment 40 includes: a location information generating unit 401 for generating location information of the user equipment; a sending unit 402, communicatively connected to the location information generating unit 401, for sending the location information and/or the service requirement information containing the location information; a receiving unit 403, configured to receive information associated with the determined service device providing the service.
Preferably, the user equipment 40 continues to transmit its location information at least until the user equipment 40 is determined to be in a rendezvous state with the serving equipment.
Preferably, if the user equipment 40 is in the rendezvous state with the serving device, the time period for the user equipment 40 to transmit the location information thereof is less than or equal to the third threshold.
The advantages of using the method of the invention will be explained below in connection with a passenger and a driver as an example.
The passenger sends the taxi taking requirement by using the client (corresponding to the user equipment), then the driver carries out order taking by using the client, and the server determines the driver successfully taking the order based on the time of the order taking by the driver, the distance of the driver or the integral of the driver. After the passenger issues the order, the passenger coordinates are uploaded every 5 to 15 seconds. The server calculates the distance between the driver and the passenger every 5 to 15 seconds, and if the distance between the two persons is always less than or equal to 5 meters, it can be determined that the passenger and the driver are together, i.e., the passenger successfully takes the car.
By adopting the technical scheme of the invention, whether the passenger successfully takes the car can be accurately and quickly judged, so that the market order can be effectively maintained, and the benefit of the passenger is protected. It will be appreciated that the above method may be applied in other applications and need not be limited to only taxi service.
