Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, in one embodiment, a device discovery method in a short-distance scene is provided, and the method is applied to a mobile terminal. The device discovery method under the short-distance scene comprises the following steps:
step 103, sending a device discovery request to the server.
The device discovery request carries a scene identifier corresponding to a close-range scene where the mobile terminal is located. The short-distance scene refers to the same physical area where the user is located, and generally refers to a place with an effective range of a sight distance range from several meters to dozens of meters. For example, the close-range scene is: the same office building, the same shopping mall, the same hotel and the like. The scene identification is a unique mark as a close-range scene. In this embodiment, the mobile terminal already knows the scene identifier corresponding to the close-range scene where the mobile terminal is located, and the device discovery request refers to that the user initiates an inquiry request to the server through the mobile terminal, and the server inquires that another mobile terminal exists in the same close-range scene.
And 104, receiving a response device discovery request sent by the server to obtain a device list corresponding to the scene identifier.
In this embodiment, a mapping relationship between the scene identifier and the device list is pre-established in the server, and a specific process of the server responding to the device discovery request is as follows: and inquiring the scene identification sent by the mobile terminal in the mapping relation between the scene identification and the equipment list, and obtaining the equipment list corresponding to the scene identification according to the preset mapping relation. And returns the device list to the mobile terminal.
Step 105, displaying the device list.
After the mobile terminal sends the device discovery request to the server, the device list is displayed on the mobile terminal after a period of time of server response, and the user can clearly know which other mobile terminals exist in the close scene through the device list. The user may select to communicate data with one or more devices in the device list. For example, the user may choose to send a request to add a friend to one of the devices or send a song to the selected device for music sharing.
According to the device discovery method and system in the close-range scene, after the mobile terminal sends the device discovery request in the close-range scene, the device list returned to the mobile terminal by the server is obtained based on the scene identification, and the devices contained in the same close-range scene all correspond to the same scene identification, so that the devices discovered by the mobile terminal are all in the same close-range scene, and the device discovery accuracy is improved.
As shown in fig. 2, in one embodiment, before sending the device discovery request to the server in step 103, the method further comprises the steps of:
step 101, receiving a wireless signal transmitted by a wireless signal transmitter, wherein the wireless signal carries a scene identifier.
The wireless signal transmitter is registered in the server before transmitting the wireless signal, the wireless signal transmitter sends a registration request carrying the scene identifier to the server, and the server stores the scene identifier to complete the registration of the wireless signal transmitter. Wireless signal transmitters include, but are not limited to wifi devices and bluetooth devices. And the wireless signal transmitter in the short-distance scene continuously broadcasts the wireless signal carrying the scene identification outwards. The user carries the mobile terminal to enter the effective transmitting range of the wireless signal transmitter, the wireless signal is received, and the close-range scene where the user is located is further identified through the scene identification in the wireless signal.
And 102, sending the scene identifier and the device identifier corresponding to the mobile terminal to a server, so that the server adds the device identifier to a device list corresponding to the scene identifier.
In this embodiment, the mobile terminal reports the scene identifier of its own location and the device identifier of its own to the server. The server establishes a mapping relation between the scene identification and the device list in advance, wherein the device list is a set for recording mobile terminals contained in the same close-range scene. After receiving the device identifier and the scene identifier sent by the mobile terminal, the server queries a device list corresponding to the scene identifier, and further adds the device identifier to the device list to prepare for device discovery of the user.
In one embodiment, after the step of sending the scene identifier and the device identifier corresponding to the mobile terminal to the server in step 102, the method further includes: and setting the discovered authority parameters of the mobile terminal in the server, so that the server controls whether the equipment identifier corresponding to the mobile terminal in the equipment list is hidden according to the authority parameters.
In order to protect the privacy of the user, if the user does not want the mobile terminal carried by the user at any time to be discovered by other users around, the privacy setting can be performed on the application program of the mobile terminal. Specifically, the permission parameter discovered by the mobile terminal in the server is set by the mobile terminal, and further, the server controls whether the equipment identifier of the mobile terminal is hidden or not according to the permission parameter, so that the hidden mobile terminal is not discovered by other equipment. The permission parameters include, but are not limited to, at least one of: a time range in which the mobile terminal is discovered, a specified scene in which the mobile terminal is discovered, a specified user in which the mobile terminal is discovered, and the like. For example, the user sets the discovered right parameters of the mobile terminal as: the time range of the mobile terminal is found to be 9 to 12 pm, and the server hides the corresponding device identifier of the mobile terminal at other times except the time from 9 to 12 pm.
In one embodiment, before the step of receiving the wireless signal transmitted by the wireless signal transmitter in step 101, the method further comprises: identifying the behavior action of a user on the mobile terminal, and triggering a corresponding equipment scanning instruction according to the behavior action; wireless signal transmitters contained within a scene are scanned according to device scan instructions.
The mobile terminal is provided with an application program, and the mobile terminal scans the wireless signal transmitters existing in the surrounding environment by triggering a button used for scanning the wireless signal transmitters on the application program. In another embodiment, an acceleration sensor in the mobile terminal detects acceleration data generated by behavior actions of a user on the mobile terminal, and if the acceleration data meets a preset condition, a device scanning instruction is triggered to scan a wireless signal transmitter in a scene where the mobile terminal is located. For example, after a user enters a hotel, the user opens an application program and holds a mobile phone to shake, namely, the scanning function of a wireless signal transmitter in the hotel is automatically triggered.
In one embodiment, after the step of displaying the device list, step 105, the method further comprises: and establishing data communication with the equipment in the equipment list through the server.
In this embodiment, in order to adapt data communication to all close-range scenes, data communication is performed between the mobile terminal and the devices in the device list through the server. The server is used as a transfer station for data transmission between the mobile terminal and the equipment, and on one hand, the server forwards the data sent by the mobile terminal to the corresponding equipment, and on the other hand, the server forwards the data sent by other equipment to the mobile terminal.
For example, a wireless signal transmitter of a WIFI or bluetooth device is deployed in a coffee shop, after a user enters the coffee shop, a mobile phone of the user receives a WIFI signal or a bluetooth signal including a scene identifier of the coffee shop, the mobile phone sends the scene identifier and the mobile phone identifier of the coffee shop to a server, the server records that the user has arrived at the coffee shop, and the user can also find mobile phones of other users in the same coffee shop through the mobile phone and perform data communication (file transmission, text chat, and the like) with mobile phones of other users through the server.
In one embodiment, after displaying the device list in step 105, the method further comprises: the data is transmitted to a single device in the device list in a unicast manner or is broadcast to a plurality of devices in the device list in a multicast manner.
In this embodiment, in a short-distance scene supporting data broadcasting, data transmitted between the mobile terminal and the device does not pass through a transfer station of a server, and data communication between the device and the device can be directly performed, so that data delay caused by data transfer through the server is avoided. For example, DUP broadcast data is used in a wireless local area network environment or a bluetooth environment.
In one implementation, after displaying the device list in step 105, the method further comprises: and sending a notice of exiting the scene to the server, so that the server removes the device identifier corresponding to the mobile terminal in the device list according to the notice.
In one embodiment, the step of sending a notification of the exit scenario to the server comprises: and receiving an instruction of exiting the scene triggered by the user through the mobile terminal, and sending a notification of exiting the scene to the server according to the instruction.
In this embodiment, the user may autonomously select whether to exit the scene, and the user triggers an instruction to exit the scene by clicking a software menu button on an application program of the mobile terminal, or the user triggers an instruction to exit the scene by a certain operation action (shake-shake) on the mobile terminal. And generating a notice for exiting the scene according to the instruction, and sending the notice to the server. And finishing the work of exiting the scene of the mobile terminal by the server.
In one embodiment, the step of sending a notification of the exit scenario to the server comprises: and judging whether the wireless signal transmitted by the wireless signal transmitter is received again within a preset time range, and if not, sending a notice of exiting the scene to the server.
The number of the mobile terminals in the short-distance scene is dynamically changed, and in order to accurately record the mobile terminals included in the short-distance scene, the mobile terminals need to actively inform the server when exiting the short-distance scene, so that the server can update the device list in time. In this embodiment, if the mobile terminal does not receive the wireless signal for a preset time, it indicates that the mobile terminal has moved out of the effective range of the wireless signal transmitter in the short-distance scene, the mobile terminal sends a notification of exiting the scene to the server, and the server updates the device list.
In one embodiment, the method further comprises: sending a registration request of the wireless signal transmitter to the server, so that the server registers the mobile terminal as the wireless signal transmitter; and receiving the scene identification returned after the server successfully registers, and transmitting a wireless signal carrying the scene identification to the close-range scene.
In this embodiment, if a wireless signal transmitter is not deployed in a short-distance scene or the wireless signal transmitter cannot work normally, the mobile terminal may also serve as a temporary wireless signal transmitter. Specifically, the user sends a registration request of the wireless signal transmitter to the server through the mobile terminal, and the server completes the work of registering the mobile terminal as the wireless signal transmitter. The mobile terminal transmits a wireless signal carrying the scene identifier outwards by transmitting the wireless signal. Other mobile terminals in the same short-distance scene can also receive the wireless signals transmitted by the temporary wireless signal transmitter, and the purpose of mutual discovery among the devices is realized through the temporary wireless signal transmitter.
For example, in an outdoor commercial activity site, due to limited conditions, a WIFI device or a bluetooth device cannot be deployed, a user a turns on a bluetooth transmission function of a mobile phone of the user a, and changes the mobile phone of the user a into a bluetooth transmitter.
